The present paper has identified thatDoomsayers predict that since with the technology we possess we can destroy the planet, we eventually will. The self-sufficiency of technological leads to the oft-quoted inference that technological events that cause change are usually irreversible. To support this contention, a lot of intellectuals who hold or expound theories usually quote similar inventions isolated in different geographic regions. Technological determinism is basically associated or compared with the general aspect of inexorableness or predictability, and is also referred to as the the technological imperative. The overriding principle of the technology is that when a specific technology poses a difficult challenge, which is doable, then this specific action must be done because it is a challenge, but technically possible (moral imperative) and must (as an operational requirement) it will eventually be undertaken, even if just for the sheer challenge of doing what is difficult but practically possible (Hasan Ozbekhan 1968). Due to the accelerated progression of technology, Donald Cardwell makes us remember that technological modernization and improvement is not created out of nothingness, but results from the victorious and dominant communication and contact that ushers in social changes, development in science and political acumen. In a comprehensive review of the tools and machines that humans have made and used throughout history, Cardwell not only emphasizes the motorized, perfunctory procedures, but also explores the fundamental, general tendencies, movement, or direction that have resulted in periods of great and even revolutionary changes and upheavals. Specifically, he pins points the eighteenth century as the cut-off point in the contemporary history of technology, describing how the progression in physics and chemistry accelerated and provided the inducement for the mechanical ideas and methods for the Industrial Revolution. Starting with the steam engine to the invention of electricity to nuclear-powered energy that drives today’s world of electronics and computers. Technology in eighteenth-century Britain was vastly different from what we see today, and their workings were also in a very different context. The eighteenth century was the period which gave birth to civil engineering an individual and diverse discipline. Most of the famous people who we would refer to as engineers today, such as James Watt, John Smeaton, Willian Jessop regarded themselves as scientific philosophers, who were trained in and adhered to the Newtonian educational institutional convention that was considered the prevailing archetype for both mechanics and the study of motion and change-producing forces. The Philosophy of technology shows the ways and means to understand the technology that could shape public policies. It also goes a long way to arrive at a concept or generalization as a result of things seen, experienced, or believed and addresses the inception of new fields of information and to follow a line of investigation.
A clear understanding of the scientific principles involved with blood must be emphasized. Depending on the injury, when the blood leaves the body it conforms to the general laws of physics. The analyst must be careful when analyzing the blood shedding events like this will enable them to understand clearly blood flow. The physical properties of blood when in fluid form, have several properties that resemble water characteristics. Both blood and water are affected by physical forces. The internal friction that is present in most fluids is referred to as viscosity. As fluids flow past each other, the layers that are present among them are responsible for the generation of these frictional forces. Also, both cohesion and surface tension forces cause blood drops to maintain their spherical shape once they drop from their point of origin. Cohesion force attracts molecules together while surface tension refers to a force created by the molecules of a fluid when they attain the lowest most stable energy configuration value possible. This value is attained by minimizing the areas that can lead to exposure of the fluid.Impact Spatter usually results from a forceful impact between an object and wet blood. This impact causes the blood to disintegrate into smaller droplets. When the impact is greater, the droplets produced will be much smaller (James, Kish, Sutton 2005). This is due to a drop in the density of blood that decreases as the movement of the blood drops become further from the blood source. A critical analysis of impact splatter enhances the conclusions on the location of the individual.
As we progressed from manual labor to large industries capable of mass production of goods, veterinarians solidified their role in society. First, as critical medical and veterinary contributors to maintaining health, providing animal care, and preventing diseases in the meat production sector. And, second, as the luxuries and leisure time drastically increased thanks to the industrial revolution, veterinarians were charged in taking care of more pets than ever before in human history.The Role of Veterinarians in Society Essay explores the veterinary history and modern veterinary positioning in society.Exceptional Individuals as Drivers of Veterinary ProgressIt is no surprise then, that in the 1800s, a famous French chemist and biologist, Louis Pasteur, undertook an important medical and veterinary task – figuring out what rabies is and how to treat it. Contrary to popular opinion, rabies is not just manifested as the word would imply – becoming rabid. Instead, it can take two forms. The more sedated form is where an animal is foaming at the mouth, with hanging jaw and paralyzed demeanor. And the more serious form of animal rabies in which an animal is extremely aggressive toward any living animal, and even inanimate objects.Pasteur soon deduced that animal rabies is transmitted via saliva, so an infected animal can easily infect others by a bite that penetrates the skin of the animal. In order to erect a defense against the rabies culprits contained in the saliva, Pasteur began to extract them from the saliva, and weaken them, by drying up the samples. Eventually, Pasteur developed a world’s first rabies vaccine. A remarkable feat for one who, by today’s standards, would be considered as a mere veterinarian dabbling in microbiology and animal research out of sheer necessity and intellectual fortitude.Pasteur’s invaluable contributions to medicine showcase that veterinarians and medical practitioners followed the same path to progress. One that leads to an ever-greater understanding of microbiology and surgical techniques, which would first be tested on animals. These are the two pillars of veterinary craft that had a critical effect on how our societies developed.Even before there was a name to label microscopic organisms, veterinarians proved critical in keeping animals healthy. This directly translated to keeping humans healthy, as animal meat and other byproducts were the mainstays of human consumption throughout history. However, not until the invention of anesthetics in the mid-nineteenth century did we see huge leaps in treating both animals and humans.We could safely say that anesthetics jumpstarted both veterinary field and medicine. They allowed for surgeries on living animals to take place, which would have otherwise resulted in torturous animal deaths. This sped up consistently competent care of animals, ultimately resulting in the formalization of food quality standards. At the end of the 19th century, veterinarians were confident enough in their knowledge to control the state of the entire food supply. By testing the animal food itself and controlling diseases that may infect livestock, it is no understatement to claim that veterinarians have saved millions of human lives. In 1930, veterinarians were pivotal in establishing the Bureau of Animal Industry to further the goal of animal care and health. This important institution implemented a wide range of veterinary standards to ensure the wellbeing of livestock: their feed quality, animal disease testing, and animal breeding policies. In turn, such formalization of veterinary standards increased the longevity of humans.Modern VeterinariansAlthough dogs were human companions for thousands of years, they were mostly treated as working animals. Arising pet culture – owning dogs, cats, parrots, hamsters, and other animals for the sake of companionship – emerged after the industrial revolution. As societies began to enjoy more abundance due to mass production of commodities and food, so did pet culture and leisure become prevalent.This created two kinds of modern veterinarians – for companion animal and mixed animal veterinarians. The first one speaks for itself, while the latter type takes care of livestock, such as pigs, cattle, sheep, chickens, horses, turkeys, etc. Additionally, you can find them employed at zoos and governmental veterinary institutions in charge of animal food control.Outside of such large organizations related to food control, modern veterinarians can mostly be found in their own private practices, or as a part of a network of veterinary clinics. They serve an important function of vaccinating pets, diagnosing them for health problems, and treating them for either infectious diseases or injuries that require surgeries. Although this is the baseline of veterinarian duties, their influence extends much further, as they advise pet owners on how to properly feed and groom them, as well as rectifying any unwelcoming behavior.Mixed animal veterinarians lead a much more intense veterinary life, as they are called from one farm or a ranch to another, from one emergency to another. As you would see a medical doctor, veterinarians carry with them diagnostic medical equipment such as a stethoscope, and surgical instruments for emergencies.However, not all veterinarians venture into the field. Some opt for public health and research. By investigating what needs to be improved in animal care, these veterinarians have a more significant and broader impact on society. By now, we all know how easy a virus can spread from animal to human, and vice versa. From swine and bird flu to the latest COVID-19 virus, medical research into protecting us from these diseases has never been more important. In addition to safeguarding us against infectious diseases, research veterinarians contribute closely with medical doctors for product testing, drug testing, and developing new experimental surgeries. In particular, for the developing field of biotechnology. In short, everything that is considered to be used on humans is first tested on animals, which is the domain of research veterinarians.Public health veterinarians work on the frontline of food safety. As animal food inspectors, they make sure that all organizations involved in the production and delivery of eggs, meat, poultry, milk, and plants, are upholding rigorous standards of control. Veterinarian work also involves paying visits to farms and ranches to advise and check on diseases. Furthermore, public health veterinarians scrutinize the meat processing plants to ensure they follow the guidelines on sanitation, humane killing, and food quality control.Public health veterinarians are usually employees of DOA – Department of Agriculture, while FDA – Food and Drug Administration – employs them as a part of their effort to conduct quality control on all food trade with the world’s nations.How does one get a veterinarian degree?Both humans and animals are complex biological systems that require years of extensive training and learning to competently understand what makes them tick and what makes them ill. While medical doctors enjoy greater social prestige, both medical doctors and veterinarians undergo an equally grueling education that requires cognitive excellence and passionate dedication. To make the transition to a veterinarian as smooth as possible, it would be prudent to start participating as a volunteer at animal shelters, or more formalized programs in high school, like the 4-H program. As far as the veterinary curriculum goes, mastering hard sciences is a necessity. biology, chemistry, mathematics, and physics. Everything else, like composition or communication, is just an extra benefit that would boost your employment chances on the veterinary market. In essence, to join veterinarians, one has to possess a practical, inquisitive, and scientific mind. One that can absorb the STEM curriculum through both high school and college.Currently, the United States holds 30 accredited veterinary universities. Given the hundreds of millions of people living in North America, this makes for intense competition, with only one out of three applicants accepted to become a veterinarian. As is the case with medical doctors, after successfully completing the veterinary program, one can further specialize in surgery, internal medicine, or preventive medicine. Unfortunately, veterinary education is quite costly and long. It takes. eight years of schooling – college plus veterinary college – on top of an average $20,000 per year tuition. Needless to say, many animals have unique physiognomies which greatly extends the time it takes to master the veterinary field.Lastly, animal lovers should seriously consider if a medical veterinary profession is for them for one simple reason – inevitable deaths. Not only those that are inevitable by the due course of nature or illness but often enough a veterinarian has to put down animals that are too sick to have an acceptable quality of life.Employment Prospects for VeterinariansIn terms of income, veterinarians are comparable to computer programmers and web developers, with some specializations yielding more profit than others. Both companion and mixed veterinary college graduates have an average salary within the range of $62,000 – $65,000. This increases with seniority when 5 years of veterinary experience goes up to about $79,000. Understandably, veterinarians not working in the field, like public health and research veterinarians, can expect a much lower income at about $53,000 annually. However, this will too grow with experience and accomplishments, with a salary increase to about $86,000 over five years. On a federal level, veterinarians can expect a similar wage range, according to the U.S. Bureau of Labor Statistics.Although vegetarianism is a growing trend for supposed health benefits, it doesn’t seem to stop the demand for more veterinarians. From 2008 to 2018, the veterinary field has grown by 33%. We can attribute this to a relatively low number of accredited veterinary institutions, which altogether output about 2,500 veterinary graduates per year. Even if meat consumption goes down in the future, the populations steadily increase, not followed by more veterinary colleges. All fields of medical veterinary practice enjoy steady growth, with the companion animal arena being the most competitive. This might change given the unprecedented economic crisis caused by the COVID-19 pandemic. However, veterinarians can count on stable employment in numerous government institutions concerned with maintaining health standards. The first among them is Homeland Security as the largest single employer of veterinarians. Suffice to say, there will always be a need for trained professionals in food inspection, health, and safety.In short, a medical veterinarian degree (DVM) is very versatile. It makes it possible to open your own medical veterinary clinic or veterinarian work within a wide variety of institutions and organizations. On another note, those who would like to become private veterinarians should keep in mind that such income is largely aligned with the economy. If the economy suffers, so does your veterinary income as care for animals is still viewed as a luxury for most people, instead of a necessity.Final WordAs one of the cogs of modern civilization in charge of animal care, it is difficult to imagine how the health of a civilization could be maintained without veterinarians. Although there are not many of them, as the American Veterinary Medical Association only holds about 91,000 members, their jobs are critical for taking care of dozens of millions of animals. Some of them opt for veterinarian work with animals directly, while others are ensuring that our food supply remains as safe as possible. The veterinary profession might be rewarding and important on a societal scale, but it is difficult and costly to obtain. It requires years of dedicated study that must start during high school and focus on hard sciences – a curriculum that is the most challenging for most people. Therefore, only those who are without doubts and have a special inkling to care for animals should embark on the path of becoming a veterinarian.Veterinarians have to be obstetricians, surgeons, and anesthesiologists all in one medical person, as situations arise. This is quite different from being a human medical doctor who specializes in one thing only. However, veterinarians are also flexible. If they succumb to a veterinarian burnout due to seeing too many animals suffer and performing too many euthanasia cases, veterinarians can always switch to a type of veterinary work that is much less involved. Veterinarians can find such work as administrators within government agencies, as food inspectors for large corporations and ranches, or as researchers.With that said, the path to acquiring that degree of flexibility must come through some measure of grueling veterinary work in order to become an experienced veterinarian. Similar to medical practice for humans, this involves long operating hours, in addition to availability for emergency calls.Resources UsedAmerican Veterinary Medical Association – Care for Animals, Veterinarians Protecting the Health of Animals and SocietyVeterinary History Society – Veterinary History.The Journal of The Veterinary History Society, (1973):25United States Bureau of Labor Statistics – VeterinariansUnited States Department of Agriculture – Food Safety and Inspection ServiceOccupational Outlook Handbook, 2010-2011 Edition.
u09d1 The first thing to spring up in my mind complements the wisdom of ancient Greeks in that all is in a of flux, nothing is the same. The thing is that looking at the all-sky map, it is apparent that without movement there is no growth and development. High speed gives way to either heating or freezing of the celestial bodies. Thus blue-shifted and the red-shifted vague specters reflect the reality of really high speed at which the Local Group moves in a constant manner. This flow is never ending and provides us with a deeper understanding of the state of affairs in the galaxies throughout the universe. Moreover, the all-sky map describes logic of the spectral analysis seen in physical peculiarity of light division. Thus, the main reaction on this map is that the orbital movement of the whole groups of celestial bodies gathered in galaxies is not limited to some definite magnitude. However, the heliocentric model of the universe is well determined on the example of the map. Thus, I can make up an inference that the hottest and the coldest parts of the all-sky map are counter-related, and it gives a specific impulse for the galaxies to move as described in the creation of tornadoes on Earth. Along with the rules evident in the heliocentric model, the opposition between cold and hot layers of the Local Group makes it possible that the universe is constantly renovating and the movement between red-shifted and blue-shifted galaxies is mutually relevant. u09d2 Albert Einstein once said the following statement: The most incomprehensible thing about the universe is that it is comprehensible (Einstein, 2007). It sounds really as a whole mess. However, I’d like to state that if Einstein came up with this characterization of the universe, then there were particular reasons. First of all, the cosmos is little learnt, and gives grounds to state that the mankind is not ready to realize the scope of the processes within the universe. On the other hand, the universe cannot comply with the general rules of Physics and Astronomy, in particular. It is a fundamental rule for everything spinning around in it. Hence, Einstein is straight-forward in identifying the comprehensive character of the universe per se. It is especially justified on the example of the solar system. Consisting of 8 planets (with no mention of Pluto), the solar system complies with different physical and astronomic phenomena overt within it. To say more, it is the matter of great accuracy in calculations and personal observation by the scientists all over the world that make the comprehensiveness of the universe come true once. It is meant that the truth is somewhere beyond our current understanding. It is not revealed today, but it does not mean that the magnificence of the universe will stay unknown to the humanity. The question is that in the great amount of different processes evident in the space scientific circles should first agree that in the complexity of the universe there are particular answers. u09d3 Finally, I think that the Big Bang theory is too convincing in terms of the cosmological approach on the universe creation. The idea is that it complements the heliocentric idea of the universe and isotropic structure of it in a broader way. Thus, with exact calculations when the universe creation started there is an assumption of how redshifts and blueshifts are likely to spread over the galaxies since that very moment. It makes scientist suppose that the Big Bang was in part inevitable and in part spontaneous, as it could or could not appear from nothing at all as it contradicts causative-consecutive line of events preceding or following it. The strengths of the theory are in its partial explanation of how things are kept in the universe and why there is a constant division of galaxies. It also contemplates with the division of energy coming from the stellar bang and stellar wind as well (Bennett, Donahue, Schneider, Voit, 2009). It also explains the flow of radiation and its impact on the creation of different celestial bodies throughout the cosmos. However, the theory does not explain reason why the initial impulse for the big bang itself appeared. Nevertheless, it distinctively describes galactic evolution of matter. As for me, I think that the Big Bang definitely happened and caused the creation of galaxies. It is both too complicated and too easy to understand. Moreover it goes hand in hand with the fundamental prescription regarding the structure of the universe. This is why the Big Bang theory has rather more arguments for the explanation of the universe per se than some opposite mismatches. Reference Bennett, J. O., Donahue, M., Schneider, N. O., Voit, M.

Divorce Effects on a Child Modern family values and pre modern family values contrast distinctively. Settlement of family dispute between a wife and a husband may fail leading to divorce. When a family breaks up children face many difficulties because their family is the most valuable thing that they have in the world (Shapiro &. Lambert). While imagining like a child, family is everything that a child has, security, social needs, psychological needs among other needs come from the family. This essay intends to show various effects that a child faces in an event of parent divorce.
Divorce may lead to anxiety, lack of trust, and emotional imbalance in children at adolescent stage (Hansch). Parental attachment during early stages of human life is very important because children tend to learn from their environment. Psychosocial theories argue that parental attachment during early developmental stages influence trust that a child develops in his or her late life stages. Evidently, a divorced family does not have time left for childcare because one of the parents is already missing. Social theorists have observed that effects of anxiety caused by divorce at early stages in a child’s life usually reoccur at adolescent stage.
Divorce influences the attention a child would get from his or her parents. Many divorces cases usually tear mental ability of a child because divorce forces a child to make a choice yet they are still young and inexperienced about events in life (Shapiro &. Lambert). Studies have indicated that many children of divorced parents had difficulties in choosing whose side they should take during their parental split cases. Researcher argue that divorce traumatizes children whose families were stable than children in dysfunctional families. Children lose confidence in relationship leading to marriage because they encounter different scenes with girlfriends or boyfriends of the parents. This on-and-off attitude makes children to develop a feeling that no attachment is secure. Social theorists have observed that emotions which children develop after their parental split has an effect in the later life.
Divorce can lead to financial constraints to a child, which might lead to termination of his or her educational life. Studies have indicated that some parents who split are unable to meet their expenses and the expenses of their children (Shapiro &. Lambert). This affect education and other essential things that a child was getting before break up. However, government has instituted policies which at protecting a child at the event of divorce. Some of the measures include forced parental financial upkeep. Studies have shown that children who lack support because of divorce conceive negative attitude towards relationships.
A child of a divorced parent may fail to acquire the right discipline required at childhood. Studies indicate that many children brought up in single family have inadequate discipline when compared to children with both parents. Psychologists believe that parental role is very important in building a child’s discipline at tender ages (Hansch). Learning theory argues that the method of discipline employed by a parent would influence the way a child would think. Since a child of a divorced parent has limited time with both parents, it is probable this child would not have the right instruction about life issues. In conclusion, divorce creates a psychological torture, physical challenges, and biological effects to the child. Many children will have to take some time to come into terms with their new conditions.

ment of Purpose. My fascination with all things mechanical s way back to my early childhood, when I badgered my parents with my favorite question: ‘How does this thing work?’ This continues to be my favorite question even now! The TAMIYA minicar I received on my fifth or sixth birthday was my greatest gift ever. As I dismantled the car, and then put it together again, with my father’s help, I discovered the joy of assembling a working model. Believe me, there can be no greater sense of satisfaction than that of actually building unity and generating movement from several disparate parts!
What started out as an absorbing past time metamorphosed into the ruling passion of my life. By the end of Middle School, I went on to make a score of different models of cars, including those with their own mini motors. I gravitated towards Physics as my favorite subject, complemented by my deep enjoyment of Mathematics, particularly Calculus. I did some independent study of Topology, and was amazed at the difference it made to my perception of objects. Based on my love of Physics and Mathematics, and my abiding interest in ‘How things work,’ the choice of Mechanical Engineering as my major in college was just a very natural progression.
Coming from a family which deeply respects the value of education and entrepreneurship (my father graduated from the reputed Korea University and my mother operates a sushi bar), the other dominant trait in my personality is my determination to make a difference to my world. My favorite past time is watching Science documentary programs on television. I consider Science to be humanity’s greatest benefactor. Scientific inventions are the bedrock of life and civilization. I intend to be in the vanguard of scientific innovation. I believe in my capacity to make a tangible contribution to improving the living conditions of my society: that is my idea of a truly intelligent Mechanical Engineer. I want to become a Mechanical Engineer who applies his skills to develop applications which make a tremendous difference to the everyday life of every strata of society.
It is my firm belief that only a rock-solid educational foundation can help me achieve my goal. I am keenly aware that the acquisition of genuine mechanical skills requires both the understanding of theory and its practical application. This is possible only in an environment which encourages hands-on-learning and innovation in the classroom. I believe that the Mechanical Engineering .Department at the University of Michigan Ann Arbor, will best meet this requirement. I aim to go on to pursue a Doctorate in Mechanical Engineering. Of course, learning is an ongoing process, which never ends, and I will always remain open to any opportunity to enhance my knowledge and my engineering skills.
I confess that I am a bit of a nerd. I am perfectly content to tinker with machines and do a spot of study even over the weekend! While this has given me formidable analytical skills, boundless patience, a ‘never give up’ attitude towards stumbling blocks, and a striving for perfection, it has also made me something of a lone wolf. However, I love meeting people of different backgrounds and exchanging views. I believe that the stimulating academic and social environment at Ann Arbor will help me strike a balance between my passion for machines and my love of personal interaction. At the same time, I am confident that my ethnicity, and mechanical know-how, will enable me to contribute to the diversity of campus life.
I am absolutely positive that graduating in Mechanical Engineering from the University of Michigan at Ann Arbor will help me realize my all my latent potential and build the foundation for my life’s mission as an engineer who will change the world.
Generally, I am intensely interested in mechanical engineering, particularly in the field of machine design. The fact that I enjoy learning Mathematics and Physics, gives me the interest and eagerness of applying the principles that I have learned in class. For instance, through the calculation of inertia and the friction available between an object being pulled on a table by determining its weight and the force applied, is an aspect of Physics. Equally important, through the use of Mathematics, one can determine what will happen when a heavier object is used, or when a greater force is inserted and vice versa. As such, I am particularly interested in the practical application of science. This is because, through science and engineering, I can be able to develop a logical approach to determinations of various mechanical problems. Moreover, engineering provides me with the opportunity to apply various theories and techniques that can be used to tackle and provide solutions to mechanical problems.
Moreover, the fact that I am always excessively fascinated with the functioning of machines has also made develop the interest of practicing mechanical engineering. In fact, during my younger years, I usually dismantled my toys with the aim of learning how the machines functioned and integrated. Quite surprisingly, I found out that changing various aspects of the machines such as motor transmission would alter or lead to a modification of how the toy operated. As I grew up, this interest developed even further and I thus started working on relatively bigger machines such as my mountain bike and my father’s old broken motorcycle. I was intrigued by the complexity of the integration and functioning of several parts of the machinery. This made me develop an understanding of how machines work in terms of converting electrical, kinetic, or manpower into movement. My choice to major in Mechanical Engineering was therefore facilitated by my liking of Maths and Physics as well as an intense curiosity of knowing how the machines integrated and functioned.
Music is utilized as a tool for expressing an idea feeling or discontent in the society thus it is classified as very sacred and unequalled property in humanity. The understanding of the properties of musical instruments allows artists as musicians to express their ideas in depth and with clarity that would have probably been unattainable previously. The changes and discoveries that occur with regards to certain behavior of a musical instrument reflect the changes of the purposes of a given set of people or society. This explains that the use that we might be having for drums today might be totally different from the role they played in ancient times.
In the world, the drum is one of the most misunderstood instruments yet it is one of the first instruments to be utilized years ago. Most of the current civilization uses the drums for different purposes than it was in the ancient ages in African and Islamic cultures. Such groups used drums for various reasons. It was mostly used in signaling since it was simple to make despite the fact that it was also loud. The drum has been used in different religious and cultural ceremonies as well as wars to signal impending troubles.
In Africa, for instance, there are different drums that are used for different purposes and are played simultaneously to give a rhythm to the audience. The most recognizable set of drums is the tom that originated from Africa. The ancient toms were made of hollow-out trees trunks and skins of animals. The patterns and beats of the time still exist to date. In around 2000 BC, the Greeks came to Africa and took with them the tom back to their land. Nonetheless, the Greeks did not have much use of the drums unlike the Romans who used it in their armies and in their orchestras. They however neglected the patterns and rhythms that the Africans had developed but after their fall and invasion of the Moor, the rhythm was reinstated.
The Moor used a different type of membrane for the drums. Unlike with the Africans who used animal skins, the Moor used the animal intestines. This made the drums make more distinct sounds unlike those of prior times, which formed the basis for the genesis of the physics of drums in the period of the middle Ages. In the current age, however, we use metal strings instead of the animal intestines alongside other designs. The evolution of the modern drum of bass originated from different parts in the world. For instance, the Indians used the bass drums and it was taken to Europe through the Turkish trade routes. It then became a main instrument in the European culture due its large sound and application in daily routines. The Europeans then went into North America to set up colonies and used the drums in numerous situations. The incoming of the slaves from Africa led to the incorporation of the missing patterns and rhythm.
I like the drum due to it bass effect and makes the sound have a masculine effect. I suppose I also like the base since when I grew up, most of the music I used to listen to would be rated highly or lowly depending on the quality of the base and beats it had which resonates well with the beats of the drum. Also, most of the music equipment such as the radios and surround system emphasize on the base thus it must have contributed to associating the bass with quality.
The students manage their schedules of schoolwork, employment, extra activities, and personal lives, they must learn about time planning, goal setting, and effective work strategies. A number of professionals at employment and student service offices are often available to help students learn about the most effective time-management and study strategies. As students continue through their education, they must learn to cope with both academic successes and challenges (Lindsay Paterson, 2005). They must deal with individuals, who they may not get along with, and they must learn to cope with subjects and classes, which seem difficult and they do not like. Facing these challenges in a university or college prepares the student for coping with challenges outside of school. In England, within the higher education system, the professional training is in direct in areas such as physics, computer science, medicine, engineering and other technical fields, some of them carried out in institutions of higher level.
The system provides for the operation of English universities organized under the departmental system and institutions organized on the basis of schools. From an academic point of view, universities operate no more than 6000 to 8000 students in total, whose growth is gradual, allowing maintain a student/teacher for not more than 1/10 or 1/12. The dedication of teachers and students is full time and is based on a very narrow coexistence, both academic and social, as well as an ongoing process of sharing experiences, advice and council (Galvin, 1996). All students are sponsored, by paying the university a lump sum of 390 pounds annually. It included accommodation, food, buying books and incidentals.
Moreover, government finance to all universities by about more than 75% of its total budget.
Running Head: QUANTUM CRYPTOGRAPHY QUANTUM CRYPTOGRAPHY By Quantum Cryptography
Quantum cryptography’s main strength is its predominantly good way of generating long, arbitrary codes (Cobourne and Cid, 2011, p. 5). A second strength of quantum code allocation is that one can use a more or less short input to produce ideally secure and arbitrary codes. This feature allows two users to share a secure code and validate the original quantum dialogue. Applying part of the product of this QKD term to validate an upcoming QKD term shows that the approaching session is also ideally secure. As a result, one can run QKD terms nearly continuously without losing security while expanding the first, short code. Both properties form a third strength of quantum cryptography in terms of security. This strong point occurs from every new QKD term code being free of all formerly used codes as this independence lowers the number of methods a criminal can infiltrate the system (Cobourne and Cid, 2011, p. 5).
A fourth strength is the future proofing of security offered by QKD. Even when a malefactor breaks through a cryptographic system at any indefinite period in the future, former messages conveyed through it stay secure (Cobourne and Cid, 2011, p. 5). Mathematics has demonstrated the absolute security of QKD networks. Even when dealing with a rival that has endless supplies of time and energy, security of QKD networks are unbreakable.
One weakness of quantum cryptography is that quantum mediums are only functional over limited space (Rothke, 2007, p. 1055). This is a technical weakness as it occurs when one evaluates the realities of QKD application. Today, quantum mediums cannot convey data quick enough to offer sufficient levels of service, which forms a second technical weakness. Thirdly, quantum optic gear is susceptible to attacks. Quantum cryptography requires costly setups for upholding quantum processing, which serves as a weakness for mathematics, computer, and physics researchers who cannot afford such infrastructure (Cobourne and Cid, 2011, p. 6).
Another weakness is the possibility of quantum cryptography “killing” mathematical progressions at any period in the future irrespective of quantum computing advancements (Rothke, 2007, p. 1055). Commercially, the promise of ideal security may not be a significant enough imperative for businesses to permit the cost of customized gear and infrastructure (Nano 2014). Since conventional cryptography offers more than sufficient security, businesses will consider the uncertain advantages of quantum cryptography an unworthy risk and weakness (Lydersen et al., 2010, p. 686).
Quantum cryptography is hackable when the QKD is built incorrectly. Hacking is possible by distorting a message once the hacker acquires the user’s secret code. Distorting a message needs the hacker to determine the factors of a figure that is the product of two extremely big prime numbers (Nano 2014). Normally, quantum cryptography makes these prime numbers ineffably big that the processing abilities of today’s computers would require more than the universe’s lifespan to crack it. However, weak codes are products hackers can use to factor these prime numbers with much less effort than normal computing power. In addition, a hacker can use an intense pulse to blind a sensor, making it incapable of seeing the photons that store the secret code (Lydersen et al., 2010, p. 686).

January, A person who influenced me: I come from a family of highly educated people. Education, to me is a family norm. I always knew I was supposed to be good at studies so that I could keep my family’s name high. Besides, being a Korean, I always assumed the responsibility to maintain the scientific pride of my family. My father wanted me to be a doctor, and so I followed him. I thought I would become a Doctor, though the profession never actually attracted me. Any way, I wanted to contribute to the field of science and technology using my craze for science and huge aptitude and liking for it. To me, scientists are the people who really make a difference in the world. Their effort gives rise to products that the whole world makes use of and benefits from. Even if a scientist does not manage to develop a product in his life time, he leaves sufficient information for others so that they may follow him in the same footsteps and ultimately reach the goal that the deceased ever dreamt of.
Benjamin W. Lee who has been a great Korean-American physicist is a source of influence for me. Coincidently, he was related to me. He died away a couple of years ago. In the period that urgently preceded his death, he had been working upon renormalization theory. Unfortunately, he could not achieve the goal he wanted to as his life ended before he could do that. Being related to him and accoutered with good scientific comprehension skills, I felt it as my responsibility to take my uncle’s mission further and complete the rest of his work. So I took it as a task. Benjamin was both my friend and tutor in scientific discussions. If there is one way I can show my respect towards him, that is by accomplishing his mission.
If I am a physicist today, Benjamin W. Lee is the most dominant reason for that. He was a physical model and realization of my dream personality. I always wanted to be like him. Many of my cousins and brothers used to talk to him generally. I remember that my discussions with Benjamin were always science oriented. I knew how he started over with the renormalization theory, and what steps he had taken in its way thus far. Although I saw it as my duty to carry forward his work, I was not mature enough to do that by the time he died as I was studying. I had to build my academic career first. So I resolved to take higher education in America in Elementary Particle Physics. Since my childhood, I always found interest in Nuclear Physics. It was fundamentally because of Benjamin, that I decided to take Elementary Particle Physics as my major subject given it was Benjamin’s area of interest.
My parents encouraged me to go abroad for higher studies because they knew that I was following Benjamin and was determined to be a good physicist. My father appreciated that I had consented to study practical physics contrary to the theoretical mood, that most of us normally go for.
Besides showing that the Sun did not revolve around the Earth, as the Bible suggests, and his many inventions, Galileos most famous contribution to science was in greatly improving the telescope. Galileo courageously led the way in the battle of science over superstition at a time when superstition was accepted as science.
Educated as a mathematician, Galileo had wished to pursue a life within the Church but his parents insisted he attend the University to study medicine. While at the Universities of Padua and Pisa, mathematics became his passion and would go on to teach the subject before leaving to study privately. Until the time of Galileo, Nicholas Copernicus (1473 .– 1543) and Johannes Kepler (1571 .– 1630) among others physics theories discovered by Aristotle (384–322 BC) were still considered fundamentally correct. While still a professor, Galileo challenged these theories, one of which led to the dual ball dropping from a leaning tower located in his hometown. According to Aristotle, heavier objects fall at a greater rate than lighter objects. Galileo disproved this theory. "The reason for one object falling faster than the other had to do with the friction each encounters while moving through the air- two objects of different weight actually fall at the same rate in a vacuum." ("Galileo Drops," 2014)
Perhaps even more famous than the leaning tower story is Galileos argument against Aristotle’s theory that the Sun revolved around the Earth, that it was a geocentric universe. The prevailing theory fit well into the Church’s teachings but it had no intention of allowing a new theory, one that made sense and was presented by a credible, respected and well-known scholar, to become public knowledge. Galileo confirmed Copernicus heliocentric theory that the Earth and other planets do what they actually do, revolve around the Sun. .
No: When newton said that for every action there is an equal opposite reaction, he was probably talking in purely scientific terms, however he defined more than physics. In nature and life this is often embodied in incidences of cause effect where ones actions eventually have consequences in the short or long term. All things, even those might appear to be the most mundane of occurrences in day to day life are subject to this phenomenal, for instance, someone who is drunk and decides to drive home anyway instead of taking a cab. The odds are, he will not have a crash, at least not on that day but by deciding to take that action, he has put himself at risk and he may cause an accident.
Nonetheless, if he does not have an accident on that day, he may become more likely to repeat the action making it more likely that he still have an accident some other time. Moreover, if he drives home and realized the risk he took, might not have been worth it, he could make a conscious decision not to drive in that condition again. In case of either way, every development will stem from his initial action of driving drunk whether it is an accident in posterity or future caution, as it is not always obvious since the actions of one person may translate in a negative effect on other people.
Ultimately, drinking and driving are a fatal combination and as long as one does both of these things, they are jeopardizing their health and life. This is because even though they may survive one or two incidence, there is a good chance that they will end up in an accident that will leave them injured or dead at some point in the future.

Although he wrote a book detailing his theories of the natural world, he delayed its publication following Galileo’s confrontation with the church and instead published The Discourse on Method four years later (Uzgalis 1997). In developing these and other ideas, Descartes eventually wrote several books regarding the nature of existence and knowledge, providing us with plenty of material to study and having a tremendous influence on those who have come after him. Remembered today primarily as the father of modern philosophy, Descartes introduced a shift in thinking from the empiricist school of thought in which people believed all knowledge ultimately comes to us through our senses to the rationalist school of thought in which it was believed that human reason was the source for all human knowledge. “He developed a dualistic system in which he distinguished radically between mind, the essence of which is thinking, and matter, the essence of which is an extension in three dimensions. Descartes’ metaphysical system is intuitionist, derived by reason from innate ideas, but his physics and physiology, based on sensory knowledge, are mechanistic and empiricist” (Watson 2002). To understand how and why Descartes came to be identified as the turning point in modern philosophical thinking, it is necessary to understand how his thinking differed from the philosophers who preceded him as well as how this type of thinking contributed to his fundamental shift from traditional thought.
Descartes was known as a mathematician before he ever became known as a philosopher. Although reports indicate he worked as a soldier in his younger years, “It is not known what his duties were exactly, though Baillet suggests that he would have very likely been drawn to what would now be called the Corps of Engineers. This division would have engaged in applied mathematics, designing a variety of .structures and machines aimed at protecting and assisting soldiers in battle” (Smith 2003). . .
1250 It was such a scary scene and the school administration had to call and inform my mother. To everyone’s surprise, my mother nonchalantly said, “It is no big deal, just hold the pressure.” Ironically, this incident spurred me to greater success in swimming. In this regard, I broke the existing backstroke swimming record that had been in existence for 16 years. Whenever I am engaged in the backstroke swimming, my mind ponders on the best ways I would use the elements of physics to improve on the sport. I am quite fascinated by physics factors that come to play when swimming. In this regard, when a person is in water, the body is similar to a seesaw. Therefore, one must find the perfect technique of balancing the body against the forces of buoyancy and gravity. Incidentally, understanding the suitable principles of marine engineering, physics and biomechanics is a pertinent feature for correct swimming and also coaching. In this regard, it is my desire to utilize the knowledge gained in engineering physics to better my future exploits as a professional swimmer.
82000 Wiener Brownian Motion can be applied in finance and physics via modeling random behavior, which exists over time. Louis Bachelier established this model in 1900 with an aim of understanding modeling fluctuations of prices in the financial markets. Still, Albert Einstein gave his contribution towards this arithmetical model, which was first established by Robert Brown in 1827. Through this model, econometricians can access past relationships and various variables such as consumer spending, tax rates, employment, household income, and interest rates. At this point, economists predict how such variable affect the future course of economic development. This assists to explain proportional growth which is attributed by economic development. It is worth noting that, economic development enhance better living, creates job opportunities, and better chances for investment. This book is useful as it lays a strong foundation for learners to comprehend economic facts that affect the market. Therefore, students can use this book to understand in depth about what attributes to economic development. The significance of reading this book is that it has great insights on the following. The concluding remarks are based on graphs analogous, which are explained in the fractal context. In explaining, the author presents graphs as that indicated in figure E1-5 that illustrate the multifractal aspect of fractal context. As intended, the author reveals the deep link between the fractal approach and finance. Therefore, from this article, readers can comprehend the following. The author describes ways of applying Ratio analysis in various markets. In his research, he found out that non-periodic cycles and fractal structure outlay evidence of the fact that the capital markets being nonlinear systems. Basically, they are two fundamental aspects of financial ratio analysis. It can be used to judge how the firm progress such as liquidity status or increasing revenues: For instance, it can be effective in making the relative performance comparisons such as the firm’s productivity .with that of the competitors.
The Nano technology is fast developing in cancer treatment. It is difficult to kill the cancer cells in the body because they are surrounded by normal functioning cells which shouldn’t be harmed. Silicon Nanobombs were made to fight this war on cancer. They have successfully been used against killing breast cancer cells as well as tumors. A type of Nanobomb, called the porous silicon Nanobomb, has also been used to kill cancer cells without killing normal cells. They are generated by an NIR light (Wake Forest Baptist Medical Center).
Nanoparticles are very specific in nature, sort of like enzymes. However, they release enzymes, proteins and sometimes antibodies to fight against their specificity. They also require different conditions of reactions which usually consist of low temperature and maybe high pressure. The best part about Nano treatment in cancer is that even though your cancer cells are being killed without any other being harmed, there are no toxic effects left in your body. It is very different from chemotherapy although it might be similar to radiation (American Institute of Physics).
Nanotubes are also part of the Nano family but are different from Silicon Nanobombs. Nanotubes are cylindrical in shape and larger than Nanobombs. They are extremely strong, one of the strongest forms of carbon structures present. However, as Nanobombs are used in treating cancer, they do not cause toxicity in the person afflicted with cancer. Nanotubes are somewhat different.
Their nature is not to kill cancer cells at all but it is used in treating breast cancer. How? Well, lasers make the Nanotubes fit for acting upon the cells to zap them up and destroy them so that the process of metastasis is unable to take place and the cancer does not spread elsewhere in the body. The heat from the laser is also at a
Then became a valuable invention that made internet accessible and more convenient to its users- this was the ‘Web’. It was in invented in 1989 by a graduate of Oxford University, England. his name was Tim-Berners Lee. He was responsible for writing the first web client and server in 1990 at CERN (which is the European Particle Physics Laboratory). His vision was to design an internet-based hypermedia system that would facilitate the uploading of information from all corners of the globe so that everyone can benefit from that knowledge . The later developments in the web witnessed the evolution of ‘Semantic Web’. It was still derived from the vision of Tim-Berners Lee of making information global and universal for its users.
Semantic Web extends the meaning (semantic) of information by enabling the web to comprehend the demands of the user and computers so that they can utilize the web for information . Semantic Web is based on a set of design principles and the concept of providing useful results to the user . Web offered services and information that could be comprehended by humans only, but semantic web is able to produce information in a manner that can be understood by computers also . Some of the main technologies of Semantic Web are:
Resource Description Framework (RFD) was initially implemented as a metadata data model. With the passage of the years, it has evolved into a mode of conceptual description and a mechanism to provide more meaning to information on the web , . Ontology can be described as the method of representing information in a formal and structured manner by the help of a set of concepts and their respective relationships. Web Ontology Language (OWL) is described as the set of information modeling languages that can be used to produce ontologies , , . Ontologies play an important role to cope with the structural differences
The dynamic systems view is an approach used in the study of development, which grows from the understanding of complex and nonlinear system in mathematics and physics (Thelen and Smith 258). The system is new, has been applied only in recent times to replace a traditional system, and is categorized into two entities, which are theories of development and general systems theories. As such dynamic stems view presents the concept that development can only be comprehended as the numerous, joint and uninterrupted interaction of all levels of a developing system. It also states that development can only be implicit as processes that unfold over numerous timescales ranging from short periods to extended ones.
Motor skills develop over extended periods, where they start from a very young age with the first movement of the neck and arms. Fine motor skills, on the other hand, involve how one uses his or her fingers and hands, as well as arms in cases of grasping, manipulating objects and reaching and this too develops from infancy and only improves towards middle childhood and adulthood. At 0 to 4 months, arms and hands are moved together covering for gross motor skills rather than fine motor skills, where children attempt to bat at objects or other forms of visual stimuli (“Fine Motor Development 0 to 6 Years” 1). From 4 months onwards, the child develops increased control over their gross motor skills, which contributes towards enhanced fine motor skills following voluntary movement such as squeezing objects and holding them in closed fists. The entire period covered for the development of motor skills, which is both fine and gross begins from childhood/ infancy until one is around 6 years old for most motor skills to develop, but not to get to perfection.
Sensation and perception are two closely related aspects of human development, both with profound differences to set them apart from each other. As such, sensation can be referred to as the method of sensing the environment in which we live through the five senses. (“Sensation and Perception”). After all information about the environment is collected, it is sent to the brain for it to interpret the different sensations, which is called perception. As such, perception remains dependent on sensation and the brain for it to come into existence and play. One such way in which perception is dependent on sensation is in the application of sound, where one person speaks and another understands. In this case, the speaker produces sound waves to communicate an idea to another individual, who uses his or her ears to collect the information the process that we shall sensation. The data is then sent to the brain for interpretation after recognition, which is perception. In this case, perception is the deciphering of the sound to bring out the message and understand the meaning.
In conclusion, the development of a child takes place through numerous processes, especially for motor skills that emerge to be dependent on each other. This is then followed by sensations and perception, which are dependent on each other. or rather, perception is built around sensation.

The curriculum can be seen as "the course of schooling" (Kirk et al. 1996). On the other hand, the Oxford Dictionary (2005) defines curriculum as the "subjects included in a course of study.” This purports the idea that every discipline needs a defined means of in-depth study and, therefore, physical education curriculum is essential as a right approach to the sports program. A methodical, scientific study approach will help in removing the anomalies like injuries and other mishaps. The right education leads to establishing good health and the right sports programs for students will be instrumental for future generations as the core for improved health and fitness.
Mechanics is a branch of physics that relates to the description of motion and how forces create motion, as well as other physical laws, which are essential for movements. Within mechanics are two sub-fields of studies: statics, which is the study of systems that are in a state of constant motion either at rest or at motion. and dynamics, which is the study of systems in motion in which acceleration is present, which may involve kinematics. In addition, the correlation between physics and sport biomechanics is a concept of work through mechanical energy for the creation of motion. Physics, through physical education, takes part in the educational system as a planned, sequential K-12 curriculum that provides cognitive content and learning experiences in a variety of activity areas. These include basic movement skills. physical fitness. rhythm and dance. games. team, dual, and individual sports. tumbling and gymnastics. Besides a variety of planned physical activities, each student needs to be trained with optimum physical, mental, emotional, and social development and should promote activities and sports that all students not only enjoy but can also pursue throughout their lives (Stilwell, 2005).
Biomechanics takes part in kinesiology for a precise description and a qualitative analysis of human movement, as well as the study of the causes of human movement, which is relevant .in professional practice for many kinesiology professionals, physical educators teaching movement techniques to students and the athletic trainer or physical therapist treating an injury (Starkey 2005). .
As a child I used to stand for hours at a construction site watching in awe as the workers worked in perfect harmony. There was nothing that gave me more joy than seeing a structure grow where none existed before. I therefore knew from an early age that I would like to be part of creating new structures. When I grew up a little and learnt more about different careers, I decided that I would be a civil engineer.
Throughout my years in school, physics and mathematics have been my most favorite subjects and my grades in both have always been impressive. I have consistently topped my class in both for many years of my schooling. It was a trend that had continued my elementary school to high school.
With time, I got to travel more and see more buildings, canals, bridges and other structures built in various designs that increased my yearning to enter into a career leading to construction. After I got access to the internet, I did comprehensive research on civil engineering and became quite knowledgeable in many topics in the subject. After I finished high school, I applied to join the (NAME COLLEGE). At first I was afraid due to notion that had been propagated into us that the course was difficult. I worked quite hard in my studies since it was a course I had passion in and I had had a good background in since I had been good in mathematics and physics. I realized that for anybody interested in civil engineering, it is not as difficult as we had been made to believe. On the contrary, I found the subjects simple, practical and enjoyable.
Over the years I have had a chance to study civil engineering, I have had the opportunity to attend various consultative for a for civil engineers in which I have had the chance to interact with civil engineers and exchange ideas on further developing construction skills. These for a have left me more knowledgeable and have triggered critical thinking in me
Chromatic Aberration in a Lens
In the study of lens, we always consider that the image obtained is perfect size, contour and color. However, in reality it is not so because when considering rays in reality we need to consider both paraxial as well as marginal rays owing to which a image can never be perfect. This difference between an image formed by a lens and the object in terms of shape, size, color etc. is known as aberration. Now aberration is of two types-monochromatic aberration and chromatic aberration. To understand the latter we need to concentrate on a prism first. A prism splits white light into its seven constituent colors. While violet light suffers maximum deviation and deviates towards the base of the prism while red color suffers the minimum deviation. The refracting angle of a prism is greatest at its center and reduces towards the sides. When white light is incident on the prism, each light is deviated at a different angle and thus they focus at different points on the principal axis. This results in the formation of a blurred and colored image. This defect in image formation is termed as chromatic aberration. Now, a lens is considered to be made up of a number of prisms and hence this prismatic phenomenon of chromatic aberration when shown by the lens is known as chromatic aberration in a lens.
Consider a convex lens on which a beam of white light is incident. Dispersion takes place and the white light is split up into its constituent colors and each of the colors is focused at different positions on the axis. This gives a blurry image. A concave lens also shows a similar phenomenon and forms an unclear image. Chromatic aberration in a lens is again of two types-longitudinal and lateral. Longitudinal aberration is the difference between the focal lengths of violet and red color. Lateral chromatic aberration is the difference in the magnification of the image formed by the red and violet light rays.

Infrared radiations and Ultraviolet rays
The electromagnetic spectrum consists of different types of electromagnetic waves all arranged according to their frequencies or wavelengths. Infrared radiation and ultraviolet radiations belong to the electromagnetic spectrum. Ultraviolet rays are emitted by the atoms during their transitions from one state to another. Infrared radiations are produced by atoms during state transitions and also by molecules during rotational transitions. Due to difference in atomic transitional energies, both infrared radiations and UV rays have different photon energies. The photon energy of UV rays is between 3 eV – 124 eV (electron Volt) while the photon energy of infrared radiations lies between 1.24 meV- 1.7 eV The wavelength of Ultraviolet rays is shorter than that of visible light and ranges between 10 nm – 400 nm while the wavelength of infrared rays is longer than that of visible light and ranges between 750 nm – 1 mm. However only their velocities in air are same and are equal to that of visible light in air.
Both of these rays are utilized for different purposes. UV rays are utilized for studying photoelectric effect and analyze their interaction with living cells. In laboratories, these rays are used to eliminate all forms of microorganisms. UV lamps are also used cautiously for treating skin diseases such as psoriasis and vitiligo. In fact the production of vitamin D in our body depends on exposure to this ray. UV rays finds use in the forensic studies as well and helps to analyze or detect body fluids.
Infrared radiations too have a wide number of uses. They are used for hyperspectral imaging, short range communication and study the structure of molecules though IR spectroscopy. They are also use in climatology studies to analyze and understand global warming phenomenon.

While I did not succeed in repairing the watch that marked the inception of a desire that would later land me at the university studying electrical engineering. The career is as interesting as it is challenging.
Dedication is a personality trait that best describes my personality. I set priorities and order my life based on the same. I developed my interest in electronics by overcoming the numerous challenges i faced in the course. I for example honed my skills in mathematics and physics two of the most vital subjects that influenced my suitability to pursue the course at the university. I did not like the two subjects from early in life. However, I dedicated my efforts in improving my grades with every exam. Eventually, I succeeded in the two subjects. My ability to develop interests in the two subjects typify he dedication and the effort I always invest in achieving my set objectives in life. I concentrate and remain faithful to my priorities until I achieve my set goals.
I work best in a team. Teamwork is vital in enhancing productivity. I learnt the value of teams in my primary education when I developed interest in football. Teamwork would enhance the success of my team. Professionally, teamwork is vital since it pools various abilities and skills thereby improving the quality of the work. Additionally, one is likely to learn from colleagues. I therefore have effective interpersonal skills and communication skills capable of facilitating my interactions with others in the team. My diplomatic approach to issues and conflicts is always instrumental in resolving any conflict that may arise in teams. This enhances the efficiency of my teams.
Additionally, I have good leadership qualities and have served in various leadership positions. I served as a prefect in high school. Furthermore, I was the captain of the football team in the school. The two leadership positions helped hone my leadership qualities. I am
Running Head: DECISION MAKING CONCEPTS Decision making concepts – U.S. Army Corps of Engineers Decision making is defined as the process of selecting and identifying the alternatives based on the predilection and ideals of the decision maker. Proper decision making implies that there are a set of alternatives that may be selected not only by identifying but also by choosing the best among them that fits with the “goals, objectives, desires and values” (Fulop, n.d., p. 1) of the organization. Decision making process involves agreement between the decision maker and stakeholders regarding definition of the problem, requirements and identification of the alternatives based on the goals and objectives of the organization. The study deals in focusing on the decision making concept with reference to U.S. Army Corps of Engineers.
Frame is defined as “the structural core of the paradigmatic mental model that brings to a problem” (Johnson &. Russo, 1994, p. 290). In simple terms decision making frames creates its own ideas and focuses on the environment. By ideas it is meant that the environmental issues should be considered that are affected by the decision (Johnson &. Russo, 1994, p. 290). U.S. Army Corps of Engineers considers environmental sustainability as their key principle. The Corp team diligently works to strengthen the security of the nation by developing and preserving the infrastructure of America and offering military facilities (About us, n.d.).
Any type of decision making is backed by reasoning. A bad decision comes from distortion and biases, which creates a series of mental flaws and obstructs the sense of reasoning. So before coming to any decision reasoning should be done properly (The Hidden Traps in Decision Making, n.d.). Behind any decision taken by the organization, the main reason is to “strengthen the security system, energize the economy and reduce the risks from disasters” (Mission &. Vision, n.d.). For this reason a group of trained individual is continuously working to provide innovative and sustainable solutions (Mission &. Vision, n.d.).
Declarative knowledge in decision making gives importance to the ordering of attributes and relative desirability of various levels within the attributes that are required to implement the strategy. Thus the experience and expertise of a decision maker is bound to be affected by the declarative and procedural memory in following a plan (Goldstain &. Weber, 1995, p.116). U.S. Army Corps of Engineers always transform the ways they do their business based on the Campaign Plan. A set of experienced, trained and certified workers, work as per the designed thoughts and actions lead by the Campaign Plan (USACE Campaign Plan Overview, n.d.).
Normative theory of decision making is based on various facets that include “idealizing, rational, super intelligent people” (Bell, Raiffa &. Tversky, 1988, p.16) who should think and act differently. The organization has a team of qualified, trained and certified professional who are expertise in dealing with projects that may aim towards different goals in different situations. For instance they are improving the waterways to energize the economy and at the same time they are devising infrastructure that would reduce damage and risk from natural disasters like hurricane.
For decision making the idea of conditional independence is quite significant because of its relationship in confounding and the estimation of causal effect (Kattan, 2009, p.16). U.S. Army Corps of Engineers closely tries to frame the main causes behind a particular situation before designing any action plan.
Interrogative logic accounts for probable answers as they appear in both pragmatic and inductive decision making (Kolak &. Symons, 2005, p. 61). The decision makers of U.S. Army Corps of Engineers are also delivering their duties based on both economic and epistemic perspective.
Any type of decision making has four common biases: “availability, representativeness, anchor and adjustment and overconfidence” (Cook, Noyes &. Masakowski, 2007, p. 46).Few years back U.S. Army Corps of Engineers was in news since some of their white workers were regularly using racist jokes in presence of black co workers which was affecting their progress in work (Army Corps Of Engineers Strikes Accord In Bias Case, 1997). The various models of decision making are discussed and it is clear that U.S. Army Corps of Engineers is working hard with a set of dedicated employees to bring about progress in America both in economic and environmental terms.

After attending classes at the university, I was given an opportunity of observing and practicing in the CT scan department at Sir Charles Gardian Hospital.
After two years of working in general radiography, I was given on job training for 3 months in order to officially join the CT department. It is a well-known fact that the CT equipment produces radiation doses that are higher than those of conventional x-ray types of equipment. Since the CT scan operator directly controls technical factors such as x-ray tube voltage, the tube current, and rotation time, which directly affect the radiation dose, the scan operator plays an important role in the whole process.
Despite these facts, most CT technologists are provided on job training just to operate the CT equipment. I believe that the primary responsibility of any radiology technologist is to obtain the best image quality while delivering the smallest radiation dose possible. In fact, my knowledge in some aspects such as the principle of Automatic Exposure Control (AEC), the effect of scan collimation in CT scan, and patient centering was very superficial. Therefore, I realized that I really needed a proper training course to study these factors in detail, especially those related to radiation dose reduction.
Although the classes were able to provide me with information on different ways of radiation dose reduction during CT procedures, all these were summarised and delivered to us within a short period of time. I feel that the CT modules should focus more on patient assessment, radiation physics, radiation protection, examination protocols, and other issues that promote safe, quality patient care.
It is a fact that rapid advances are being made every day in diagnostic radiology and CT technology in particular. It is really a challenge, therefore, for CT technologists to cope up .and update themselves with newer advances. . .
The importance of the proper way in which to write a research paper It is very important to think about the research approach before starting the research process, as the approach affects how research questions are formulated, and how data collection takes place. The conclusion may or may not be different.
Generally, there are four categories of research approaches: logical theoretical research, quantitative or experimental research, qualitative or observational research, and participatory action research. Let’s take an example. If we have to evaluate whether a variable relates to a given situation, we conduct the qualitative research, which is base on observation. Experiments and surveys are conducted, with the use of interviews and questionnaires, to seek answers to the research questions and come to conclusion. For example, in the research with research question: how coffee intake affects sleep, the researcher will follow the qualitative approach, going to participants of the study, and conducting interviews, questionnaires, and surveys, to know how caffeine intake is related to sleep. He will not use the quantitative approach, which is best used for hard scientific evaluations, like those in physics, and is based on empirical data that can be used for statistical analysis. Hence, when the aim is to gather general information about a subject matter, like why something happens or what people think about it, qualitative research is used. but, when the researcher has to go for numerical evidence, he uses quantitative approach. The research question also gets modified with each kind of study.
The comparison of above mentioned approaches illustrates that it is very important for the researcher to think about the research approach before starting the research, as every approach undergoes entirely different steps. Research questions get modified, even if conclusions remain the same.
Both at the micro and macroscopic the effects of this force are observable as these photons have zero rest mass that allows interactions at long distances (Newton, 1949). Photons can be best explained through quantum mechanism and they have wave particle duality that means they exhibit properties of particles and waves both. Like for instance a photon can be refracted by the lens and can display wave interference with itself and also perform as particle while its position is measured.
Max Planck, In the year 1900 working on the black-body-radiation suggested that energy can only be released in packets in the electromagnetic waves. In 1901 he named these particles energy particles. The quanta was used meaning particles. Later Albert Einstein in 1905 suggested the electromagnetic waves can exist in discrete-wave-packets called light quantum. The word photon was derived from a Greek word for beam. Photon was the term coined by Gilbert Lewis, in 1926 via the light concept in discrete particles form photon had been present around for ages and had been formalized in Newton’s science of optics’ construction. In Physics photon is denoted by a sign γ derived from the gamma rays whereas in Chemistry it is denoted by hv.
The photon is an elementary particle which has no mass. It is impossible that a photon decays on its own although its energy can be created or transferred through interaction with the other particles. They are electrically neutral and rare particles that are similar to their antiphoton and antiparticle. Photons are the spin 1 particles with spin axis which is parallel to travelling direction. This feature allows the polarization of light.
Light has properties of particle and wave both. When the light is taken to be as a flow of particles then these particles are known as photons (Bialynicki- Birula, 1994). Each photon carries a distinct energy packet. The beam intensity is dependent upon the photon
The prison system that the country uses today and in the 20th century is the same. In the 20th century, prisons experienced major reforms in terms of structure and staffing. However, one major aspect that the system did not accommodate was the technological characteristic. Technology in major institutions is one very important characteristic as in the 21st century. most of the education relayed to students is through technology. For example, calculators have come in as a great deal to serve contemporary students with faster ways of calculating in fields such as chemistry, physics, and mathematics. If these people had gained the knowledge, they would not go back to society to commit the crimes but would rather make something worth.
The economic condition in the outside world is one other factor linked to the high amount of repeat offenders in the prisons. In contemporary times, the rates of recession have been steadily on the rise and thus making people engage in activities that will serve to help them gain a meal for the day. The economic factors extend so far such as even professionals such as doctors engage in activities that do not fit their job description. An example of this is a doctor who may go way out of his career path to sell prescription drugs to addicts in an effort to make the extra cash.
According to Malthouse who is a well-known author on the issue, these conditions affect the professionalism of people and when they stray to carry out activities that do not suit them, the resulting factor is the lack of essence to the career that a person has (Malthouse and Roffey-Barentson, 2010). With the lack of essence, it is common to find the person forfeiting his job and concentrating on the illegal side job as a whole. Through this, the person may lose certain concepts taught in the professional school attended due to lack of practice .and this would eventually render a former professional a criminal.
Observations" NEWTON Newton’s Second Law – Conducting an Experiment Newton’s Second Law involves force and mass as being the main variables that impact how an object obeys gravity and falls. Therefore, when a heavy rock and a feather are dropped at the surface of the earth, they are going to drop at different speeds. The feather is going to flutter and float gently in the friction of the air, and stay in the air longer than the rock, even if they are the same size. The feather has less inertia than the rock, so it does not want to drop straight down. The rock also falls faster, because they have different masses: the rock has more mass than the feather, and therefore it falls more quickly when it is within the earth’s atmosphere. The force of gravity is greater on objects that have a heavier total mass.
2. When a rock and a feather are dropped on the moon, they are going to float in the air rather than falling, for a much longer time. There is no friction from the air to influence the feather, on the moon. “The weight of an object is different on the earth and on the moon since the strength of the gravitational field is different” (Newton, 2009). The hammer still has greater mass, so it will still hit the ground on the moon, faster than the feather.
3. The rock falls faster and accelerates faster than the cotton ball, because there is not as much air resistance on it.
4. The containers fall at the same rate, apparently. I dropped them from about five feet: a drop of several stories may have been different. When the objects are in the containers, the air resistance is equalized.
Newton’s Third Law – Research and Predictions
1. In terms of the logic of the horse, when the horse pulls, it puts force on the earth. It contacts the earth with its hooves, and pushes against the earth. At the same time, the earth exerts force itself. Meanwhile, the horse is exerting force on the wagon. It is a system of pushing and pulling, in which various forces have an impact on each other. The logic of the horse is that it will cause the wagon to accelerate, because of the force of the horse.
2. This may seem to make sense, but what the horse is stating incorrectly is the relative importance of its force on the wagon. The wagon and the horse are separate, so they have different levels of force acting on them, independently. The forces at work on the horse, are not the same as those at work on the wagon. The relation between the horse and the wagon is incorrect.
3. The force between the cart’s wheels and the road is another force that can be added to the picture. From this perspective, the force exerted by the horse on the ground, has an effect on how the wagon moves. This then questions the fallacy of the non-relationship or separation of horse and wagon, into distinct entities which interact with each other physically.
4. It is a common idiom that people should pull themselves up by their bootstraps, which means that they should be independent and self-sufficiently resilient. However, it is impossible. “If they arise from the two masses themselves, they must be equal in magnitude but opposite in direction so that no net force arises from purely internal forces” (Newton, 2009). Pulling oneself up by one’s bootstraps involves only internal forces.

The Merriam- Webster Dictionary (2003) defines morality and morals as the relation of principles of right and wrong behavior. It denotes the ability to choose between good and bad deeds. The aptitude to choose righteousness becomes the greatest virtue. For instance, the action of an individual to apply adequate value to human life versus value in material possessions, the worth of a life is more than that of a vehicle. What is the greatest virtue, saving the life of a child or taking the life of an elderly person due to pain? Should lying be punished when its outcome serves the greater good? This archival thesis will be devoted to the study of morality with the central framework of the Theory of Moral Development by Kohlberg (1984). The objective is to provide a foundation for the following questions: How can one make a person more moral? Does knowledge of right and wrong lead to more consistent moral behavior execution? What can moral education offer the framework of society?
In order, to fully understand all of the implications of Kohlberg’s theory it is essential to evaluate the predecessors and the person of Kohlberg. There will be a chronological description of theories influential to Kohlberg’s research. Piaget’s theory of cognitive development and moral development will be analyzed. Although, his research devoted most of its energies to children it has provided an invaluable foundation for unveiling the development of morality that laid the ground for Kohlberg’s Theory of Moral Development.
The developmental-structural approach was first taken by the Swiss psychologist Jean Piaget (1896-1980). He was a Swiss psychologist who developed a theory of child development known as genetic epistemology. This theory has had a wide impact, not only on psychology and education but also on fields as diverse as .linguistics and physics.
The aim of using Matlab is to obtain precise and accurate results and to save time. According to Chapman (368), Matlab assists us to perform engineering and scientific calculations that were involved in the experiments because it is capable of solving any technical problem.
To obtain the movement of the platform with minimum shake we put some codes in Matlab and filtered that by some other codes. After obtaining the tilt angle in week one, we attempted three-dimension positioning by using a two-axis accelerometer mounted at the right angles and a three-axis accelerometer. The Matlab code used in week one was2-d-vector.m which meant that you were to have a two-dimensional plot. In the second week, we used the Matlab code w1-3d-vector which meant that you were shown the Graphical demonstration of eigenvalues and singular values of three-dimension and w2-3d-vector which represented the Characteristic polynomial, eigenvalues, eigenvectors of the three-dimension vector

The pursuit has led to the physicists forming several pyramid ideas. In the book, Carroll (2012) gives the history in relation to the formation of the Higgs boson. The story begins 2, 500 years ago with the Greets and ends with an atom smasher that led to Higgs discovery. The atom smasher weighs 12, 500 ton and is the tool used in the discovery of the Higgs boson.
Human curiosity is the fundamental thing when it comes to invention and innovation. Since the ancient Greek’s time, humans have been curious to understand the basic principles that govern the Universe functions. The desire to understand the world is the basis of particle physics. If not the desire, it would not be important since it does not affect our day to day lives. 1970s is the period under which the characterized by a distinct experimental result that was deemed impossible before. The innovation that was experienced among the machines had improved greatly during this period. 1970s is the period that the Standard Model (Carroll, 2012) which was a pillar stone on the Higgs boson discovery. The model helped in the description of the elementary particles like the gluons, quarks and neutrinos.
Carroll (2012) describes matter to be made of small particles that are known as atoms. Atoms are not divisible and consist of nucleuses that are made of neurons and protons. The neurons and protons are indivisible and orbited by a number of electrons. The neurons and protons are made of smaller particles that are called quarks. Quarks and electrons are referred to as elementary particles. The atomic nucleus neurons and protons are made of ‘up’ and ‘down’ quarks. Every single piece of matter is therefore made up of up quarks, down quarks and electrons. Matter particles are of twelve distinct kinds broadly divided into six quarks and six leptons. The six quarks interact closely and are confined in larger groups like neutrons and protons. The six
July Re: Cursory Internet Research PERSONAL INFORMATION Jon Stewart was born in Lawrenceville on November, 1962, in the city of New Jersey. The boy was a natural born aggressive comedian, so that by 1989 he was already on the theater scenes hosting comedies with a grand launch of an MTV talk show, The Jon Stewart Show (Jon Stewart – Wikipedia, the free encyclopedia 2012). Thereafter, he has appeared on several TV shows and programs becoming the anchor of the Daily show in 1999. The highly progressive man is, hence, on demand as a feature artist and film actor. His progressive path can, therefore, be traced from comedy to becoming a television host of the central comedy (Scherer 11).
Jon’s mother was an education consultant and a teacher. his father was a professor of physics at the college of New Jersey who now handles online courses at the Edison State College. Stewart’s parents are today separated and the actor considers him a subject of anti-Semitic bullying when he was a child. He farther goes on to describe himself as a Eugene of debs while in high school (Scherer 33).
The fame as exhibited by the actor and TV host comes in handy with a variety of implications ranging from threats to content that are directed towards defaming the character of the actor. This is further supported due to the development of the modern networking sites, which are likely to fuel the propaganda as they are propagated. The following sites: http://www.thedailyshow.com/. http://www.facebook.com/thedailyshow. http://twitter.com/thedailyshow. http://www.rallytorestoresanity.com/, represent a positive replica of the artist since they have not presented any negative, threatening or inappropriate content about the celebrity’s acts (The Daily Show with Jon Stewart – Political Comedy – Fake News | Comedy Central 2012). Instead, the film actor has proved to be on demand, having handled several awards shows and received all positive accolades.
He hosted two consecutive Grammy Award shows both for 2001 and 2002. further, he hosted the 2006 Academy Awards ceremony. All the comments about the hosts’ up to date are so positive of the actor and comedian. Among the films he has received praises for after appearing as one of the leading actors include the Box office bomb Death to Smoochy together with Robin Williams and Edward Norton (Scherer 126).
Both print and hard media have furthered praises on the comedian and actor Jon Stewart. From the articles we have gone through, we have not found any with threatening or inappropriate information directed towards Jon Stewart (The Daily Show Fan Club | Fansite with photos, videos, and more 2012). Besides being a talented actor, Stewart has been published as a writer in several magazines among which we have The New Yorker and Esquire. So far, the author has completed two books: Naked Pictures of Famous People and A Citizens Guide to Democracy Inaction, which was the best selling at the time (The Daily Show (TheDailyShow) on Twitter 2012).
Recently Stewart’s mocks claim that it is too early to talk about Gun Control. The actor cum comedian has though taken it head on with the media on such claims most so after the movie theater in the Colorado was released (Rally to Restore Sanity 2012). He reacted by opposing the claims arguing that it was exactly the right time to talk about the issues. This reactions received massive support though there came a few opposing forces.
According to the cursory research conducted, there were not any controversies as to the actor’s upcoming travel plans. In addition, there were not any references concerning this (Rally to Restore Sanity 2012).

We used excel tables, bar graphs and smooth line graphs to analyses the data obtained from the laboratory. We found out that during half life time interval the coins will decay to half its initial number just as it will occur with real nuclei decay. Also, that the decay process is an exponential function curve. To decay to zero, we need approximately three times the half-life of the coins. The throwing of the pennies proved to a good model for the nuclei decay process as shown by the normal distribution frequency curves
Radioactivity is the natural, spontaneous process in which a nucleus of an unstable atom loses energy by emitting particles such as gamma, beta or alpha particles. Past studies (Martin 2006. Pg 15) have shown that these radioactive nucleus though are randomly emitting particle, the time it takes for a particular radioactive element to reduce to half its original amount is always a constant. In this project, we set out to perform a radioactive decay process and find half-life by using the flipping of pennies. We set to investigate if half of the coins decays at each flip and also investigate the relationship between the accumulated coins decayed and the coins left curves. If we assume that the coins were being flipped at equal interval of time (half-life) we wanted also to investigate if the number of coins that decay each time is half the original number. With these objectives, we set the following hypothesis. that tossing a coin is a good model for radioactive half-life (Cook 2010, Pg. 46). Approximately 50% of the coins should decay at each throw and that it should take approximately three shakes to get to zero coins left. In the second set up hypothe\sis were that. four coins should decay most often on the first throw. Our prediction of the percentage decay first throws calculation is 50%. The distribution of the number of coins that decay on the first throw should be bell shaped (Cook 2010, Pg.
The Moral Life of Babies The thesis ment of this article is, Although the growing body of evidence suggests that humans do have a rudimentary moral sense from the very start of life, babies and young children do not lack a sense of right and wrong.nbsp.Instead, their sense of right and wrong they naturally possess diverges in important ways from what we adults would want it to be (Bloom Web).
Bloom has an articulate label of naïve physics. He deduces that the truths of physics are universal in that objects obey the same physical laws everywhere. He equally had a well-defined label on naive psychology. He noted that the truths of psychology are universal in thatnbsp.people everywhere have minds, goals, desires, and beliefs.nbsp.In light of this, he defined a baby’s naïve psychology by exploring what babies know about the minds of others using the looking-time methods. He equally reckons a sympathetic parent’s acceptance to the popular claim that babies are wonderful learners. However, developmental psychologists negate this popular claim by noting that the ignorance of human babies extends well into childhood (Bloom Web).
Bloom’s Support towards His Thesis about Naive Morality
Bloom relates with other psychologists that the ignorance of human babies extends well into childhood and adopts the convectional view that young humans take a surprisingly long time to learn basic facts about the physical world and about people than they do to learn about morality. There are various studies, using the looking-methods to explore what babies know about the minds of others. In a study by his wife, Karen, he found that babies could do rudimentary math with objects. In this study, babies expect the same number of items like adults and are thus surprised if the contrary happens against their expectations. In another study, babies proved to have an actual understanding of mental life where they grasp how people think and why they act as they do. Indeed, though babies expect inanimate objects to move as the result of push-pull interactions, they expect people to move rationally in accordance with their beliefs and desires. Other studies show the existence of behavior in toddlers that is altruistic in an even stronger sense where they give up their time and energy to help a stranger accomplish a difficult task. In a study investigating what babies, think about two particular kinds of action involving helping and hindering, a three-dimensional display in which real geometrical objects, manipulated like puppets, acted out the helping/hindering situations was in application. The study found out that found that six and 10-month-old infants overwhelmingly preferred the helpful individual to the hindering individual.
Characteristics of Adult Morality According To Bloom
Bloom realizes that the idea that good acts should meet with a positive response and bad acts with a negative response is one of the major aspects of adult morality. Indeed, the notion of fairness is universal. In addition, their is value on loyalty and kindness, a distinction between acts of cruelty and innocent mistakes, and a category of people as nasty or nice in the definition of adult morality(Bloom Web). Moreover,nbsp.compassionate feelings and impulses, notions of praise and blame, notions of equality, generality, universality, and freedom for all characterize adult morality.
The article was particularly interesting to me. Specifically, I find it interesting that despite their overall preference for good actors over bad, then, babies have interest to bad actors when those actors are punishing bad behavior. Their attitude towards bad actors mirrors adult actions whereby we are well aware of the bad people in the society.
I find it problematic that the research establishes no plausible relation between adult moralities to our reproductive success. The article did not address the issue of possibilities of genetic influence on children behavior especially in morality. The big question worth asking is what would happen to morality of babies if they were left in an isolated state. Would they develop different morals or would the morals be a reflection of the general society?

Q2.1. a) A physical quantity can be expressed as a product of fundamental quantities (Mass, Length, Time etc) raised by certain exponent and this expression is termed as ‘Dimension’ of that physical quantity.
where g is the gravitational acceleration, β is the coefficient of thermal expansion, DT is the temperature difference between hot wall and the surrounding, L is the characteristic length, and u is the characteristic velocity.
Q 4.2. a) Let us assume that the laminar diffusion flame height (Lf) is directly proportional to volumetric fuel flow rate (Q.) raised to the power ‘a’ and diffusion coefficient (D) raised to power
Stress is a result of physical and emotional nervousness and anxiety that a person suffers due to pressures from people living in his surrounding or events happening in his life. We say that we are stressed out when we feel that things are becoming too much uncontrollable, we become overworked with finding solutions and start wondering if we can at all deal with the strain imposed upon us. According to Richard Lazarus (1999), psychological stress was in fact first adopted from the comparisons made in physics and engineering as Robert Hooke discussed how an external force creates strain when it is applied on a structure. Over time, this particular use of stress was applied to models of psychological stress in which the stressor becomes the external force while the stress response becomes the reaction of one’s body to the stressor. As proposed by Lazarus and Folkman (1984), psychological stress is a relationship that exists between an individual and his environment that is considered as a threatening force to his well-being. A complex interaction exists among the events that are happening in the environment, how an individual perceives such events, and the means that he has to deal with in determining the level of stress that he is experiencing. Individual differences influence response to various environmental stressors.
Stress at work is the stress experienced during one’s job or at the workplace. The stress that a person experiences otherwise gets added to the stress that waits for him at the workplace. Segal et al (2008) assert that while some stress is a normal part of life, excessive stress interferes with your productivity and reduces your physical and emotional health, so it’s important to find ways to keep it under control.nbsp.
Political science is the study of behaviour of people in regard to governance, organization and power play. As such it not only studies the public actions of political activists, but also studies the making and functioning of political institutions, structures, laws and constructs of politics. Since political science deals with observation and deductions of theories and facts from actual situations, it can be classified as a science. An empirical theory of politics, then, is an explanation of why people behave the way they do politically (The Powermutt* Project). Ancient philosophers like Aristotle, Plato, and Socrates in Greece and Chanakya in India studied politics on basis of observed phenomenon. In the medieval times, Machiavelli, of the Italian Resistance movement was among the first to study politics in a systematic way. Later, with the advent of various democratic movements, and intellectual resurgence in Europe philosophers like Hume, Hobbes, Roussseau, Marx, Locke and Voltaire made vigorous studies in political science
In the present times, political science is being studied both as a normative and behavioral science and is generally categorized as social science. Though research methods like statistics, stating and testing of hypothesis, drawing of inferences and supporting a political theory with observable facts, and making political analysis thereof, is commonly practiced, yet, political science is not considered an exact science like physics, chemistry, and mathematics. This is because, although, some postulates can be proved true but they are not as fixed, rigid and universally true as the Laws of Motion, Laws of Thermodynamics, Quantum Theory, etc. Political science lacks the exactness and precision with which exact or natural sciences are studied. Thus theories, concepts and their causes differ in political science unlike those of exact sciences. For example, the causes of Republicans
ne has the ability to choose from the multiple patterns of lives with the chance of being embedded in one of the possible past-future pairs (Santas 39). The possibility of breaking out of limitations of only being able to exist in the present has led to many depictions of possible situations where human beings are able to freely move through the past present and future. Obsession with changing the past has not been limited to popular culture but has also featured in academic field such as physics and philosophy. This essay argues against the notion presented by some physicists and philosophers that one can travel back into the past to change based on the inconsistencies of time travelling.
In this kind of fantasies, many tend to perceive an instrument such as special machine that will facilitate the backward time travel, think of a special machine which will enable man disappear from one place and time and reappear at a past time in a different or same place. There is a philosophical line of thought based on the existence of what is called a closed timelike curves (CTCs) discovered by philosophers and physicists working on time travel. CTCs are curves in space and time which provide possible paths of bodies to move through various universes. The model containing CTCs was discovered by Kurt GGdel in the 1940s and was believed to be models of the Einstein field equations (Seaman and Ssler 141).
Based on model, Godel makes a theoretical assumption that it is possible for one to travel and come back at the exact time and place by making a round trip on a rocket ship in a suitably wide curve. This means that the object will get back to its past to the exact moment when it commenced the journey. The argument presented by Godel is based on the belief by some philosophers and physicists that the past, present and future equally real. These views on past, present and future represent the ideas of externalists group of theorists who argue that there was no
This essay will not deeply address the issues as the main project will follow that will handle the topic adequately.
The acronym STEM refers to Science, Technology, Engineering and Mathematics. It is a newly introduced curriculum which advocates for the teaching of science, technology, engineering and mathematics through integration. Meaning, it is a new approach which adopts an applied and interdisciplinary strategy while teaching these subjects without necessarily teaching them in isolation. By blending Chemistry, physics, In formation Technology, computer, engineering, mathematical science, geosciences, astronomy, life science and social sciences, the curriculum will be encouraging students to learn about practical problem solving skills which are of course essential in their day to day experiences.
STEM was established in the United States with the aim of solving the problems created in education and offering of science subjects. The project is aimed at making the STEM related fields more relevant to the students. This is aimed in turn at ensuring that the students become more creative in the future and come up with new projects that can help the country scientifically. The problems in security are a major concern in many countries and it was also one of the highlighted problems that are to be addressed by the STEM project once it goes underway. This essay will look deeply into the idea and point out the strengths it has depicted and the limitations including the remedies that can be implemented to make it a more effective method of bridging the scientific and technological gap that is created in science subjects.
However, in order to achieve its objectives, STEM program will have to be introduced to the learners as early as possible. As a matter of fact, it will be shift from the common tradition in which the STEM subjects are taught differently in schools. As a new system aiming at reaching the greatest possible
Enzo Ferrari the legend behind the name Ferrari had a passion for car racing which motivated him to come out with the brand name which is today a household name in the field of F1 races. It was in 1945 that the work started on designing and building the very first Ferrari, a project which was being prepared around 12-cylinder2 – a first in the history which went on to provide a direction to the car in general and car racing in particular. Ferrari was the first car to use 1.5 litre unit in a V12 configuration. Since then the company has not looked back.
Ferrari, the car was the brain child of its founder Enzo Ferrari. The journey begins with the foundation of Scuderia, sort of a club, on 16th November 1929, exclusively for participating in motor-racing competitions. Enzo Ferrari an integral part of Alpha Romeo for many decades, parted ways in 1929. When Ferrari left the club, he was not allowed to have his name on any of the cars or clubs for the next four years. But his resolve and patience saw him through in his ventures and he started with an 8-cylinder, 1500 cc sports spider, named as 815. It was only in 1946 that the name Ferrari comes into being for cars. The company has not looked back since then. Thereafter came its association with Michael Schumacher in 1996, which further helped in establishing the brand equity called ‘Ferrari’. The F1 racing is now an integral part of Ferrari. In fact F1 racing has now become a big industry in itself. Such developments have started driving other car manufacturers as well into the race and serious manufacturers like BMW have also started experimenting with the sporty driving. Though it may sound boring to people watching the racing on the tracks, its television clippings have started commanding huge premium. This potential was foreseen by Mr. Ecclestone of ‘Formula One Administration’, who produces the electronic feed being watched by over 40 billion viewers (The
Blood spatter analysis was sensationalized during the O.J. Simpson trial.
Bloodstain pattern analysis, hereinafter referred to as (BPA), began in the late nineteenth century. However, while it has been studied for such a long time, the science and exact art of bloodstain pattern analysis has only recently become a staple in crime scene analysis. The first known study of blood spatters occurred at the Institute for Forensic Medicine in Poland, by Dr. Eduard Piotrowski. His studies resulted in the publication of his book Concerning the Origin, Shape, Direction and Distribution of the Bloodstains Following Head Wounds Caused by Blows. The study of BPA is a combination of physics, biology and math. The investigation can take place at the scene of the crime or through the pictures that crime scene investigators take at the scene of a crime.
The first time that blood spatter became highly sensationalized was 1955 in a case called Ohio v. Samuel Sheppard. Since 1955 when Dr. Paul Kirk first presented a bloodstain evidence affidavit in State of Ohio v. Samuel Sheppard, expert testimony on bloodstain interpretation has gained wide acceptance in U.S. courts (James, 1998). At trial, an affidavit purported to be an expert opinion was submitted by Dr. Paul Kirk. This 1955 case landmarked one of the earliest instances of our legal system recognizing the importance of blood spatter analysis in investigating the scene of a murder. The testimony offered outlined the position of the murderer or suspect and that of the victim. Ultimately, despite strong objections, the testimony demonstrated that the victim was assailed by the defendant’s left hand.
The initial step in the examination of blood at any crime scene is to be fully aware of how bloodstains are characterized. (Department, 1998). There can be no characterization without answering three crucial
