...When you throw a football across the field to your friend, you are using physics. You make calculations for all the situations that can occur, such as: distance, wind and weight of the ball. The farther away your object is, the harder you have to throw the ball, or the steeper the angle of your throw, as if your object is on top of a hill and you was at the bottom of the hill. This calculation is done in your mind, and it’s called physics. You just don’t call it that because it’s so natural. Physics the branch of science concerned with the nature and properties of matter and energy. The branch of physics that is most relevant to football is mechanics. Watching a football game could be teaching you something other than who threw the...

...Brandon Hergott The Physics of Tackling in American Football The game that America has come to know and love may have more behind it than everyday viewers and fans realize. Physics fuels every aspect of the game of football and is evident in the collisions that take place on every play. Watching a game of football can be a great learning tool to anyone interested in better understanding the laws of physics. Many great examples are provided on every snap. Mass, force, momentum, velocity and torque all play significant roles in the tackling action performed by players and the better you understand these terms the better you can begin to understand the game itself (Gay). Most of what football players and coaches know about tackling is more instinctive than anything. They understand more about the physics of the process more than they realize. Force, mass, acceleration, momentum, torque, velocity, inertia and center of mass are important terms that become relevant when discussing the physics of tackling in football (Gay). Acceleration is the rate of change of velocity in a certain period of time. Force in football can be described as the influence that one player has on another while causing him to accelerate. The amount of substance an object is made up of is the mass. Momentum comes as the result of the product of the mass of a moving object and its velocity. Inertia is the resistance of a moving object to a change in speed or direction, and also the resistance of a stationary...

... GE 253 Physics Albert Einstein’s Contribution to Quantum Mechanics Albert Einstein was one of the greatest minds in world history. Einstein is known as a brilliant physicist who contributed more to the scientific world than any other person. His theories on relativity paved the way for how science currently views time, space, energy, and gravity. Einstein was so advanced in his thinking that his studies and work set the standards for the control of scientific energy and space explorations currently being studied in the field of astrophysics. Albert Einstein's most noted contribution to the world is his theory of relativity. By 1902, Einstein was working on combining time and space, matter and energy. In 1905 when he was only 26 years old, he published a paper on relativity. This paper showed mathematically that the speed of light is constant and not relative to its source or to the viewer. Einstein had actually written an essay when he was only 16 years old on relativity, which became the basis for his published paper. The greatest result of relativistic physics was Einstein's famous relation, E=mc2. In this, he was able to prove that any increase in the energy, E, of a body must lead to a corresponding increase in its mass, m, these increases being related by a factor c2 , where c represents the velocity of light squared. In conclusion, Albert Einstein ranks as one of the greatest people for his contributions towards physics and his part...

...Physics is all around us. It is what causes the lights to buzz with electricity, the car on the streets to go from point A to point B, and our televisions to run so we can watch our favorite shows. According to Webster dictionary, physics is the science of matter and energy and of interactions between the two. In all physics consists of energy, kinetic energy, potential energy, velocity, acceleration, mass, force, and gravity. Without physics many things would not be possible. In fact, when a person is driving their car they are suing momentum (the quantity of motion of a moving object) and acceleration. Over time our general understanding of physics has helped us develop greater technology than society thought possible. For example, many years ago society believed that flight was impossible until two brothers, the Wright brothers, invented the aircraft. Now of course that was with many trial and errors. According to Bernoulli principle an increase of a flow results in a decrease of pressure. When air hits the leading edge the airflow above the wing travels faster than the flow below the wing. So therefore, the pressure below the wing will be higher than the air pressure above the wing. Because of this difference in pressure, lift is created, and pushes the wings upward. Be that as it may, this is not the only physics principle at work One must also apply Newton’s 1st (every body remains in a state of rest or uniform motion unless it is acted upon by an external unbalanced...

...Name Professor Course Date Isaac Newton the Last Magician Biography This is a one hour movie documentary narrated by Helen McCrory trying to give an insight to the life of Isaac newton and how he changed our understanding about how the universe works. The documentary asks question to experts of the history surrounding Isaac newton. In the documentary Isaac newton is brought out as a pessimist as he would enjoy his own company, his life revolved around research and a lot of studying in the laboratory in religious activities like heretical, alchemy and also the study if the hidden. Newton did not believe anything that he read, this was evident when he was the age of twenty one by declining to agree with scientific research which was more than two millennia old and decided to come up with his own through conclusion and to do this he had to perform a number of experiments. We get the notion that he was a skeptic and anything could be questioned of its legitimacy. Newton had a secretive life that came to light two hundred years after his death, this was his passion for cultic behavior where he considered himself a scientific Christ who was sent to save the world from scientific fiction, this is ironic as he was also born on Christmas morning just like Jesus the messiah in the bible. He is called the last magician because after his death there has not been any other iconic person like he was that has made a fraction of the changes in science that he did. His discoveries...

...Kruyper (trained mathematician). While attending his last years of High School in Rotterdam Netherland Edsger Dijkstra knew what he wanted to do in life. He wanted to represent his country at the United Nations. Even though he was still in high school, he formulated a plan to achieve this goal of representing the Netherlands in the United Nations. He decided to get a law degree. After receiving the maximum highest points possible in the following areas: mathematics, chemistry, biology and physics on his final examine. Everyone starting with his loving and supportive parents to his very motivational teachers convinced Edsger that a career in the field of science would be an outstanding career move for him. So, Edsger Dijkstra headed on to the University of Leyden. There at the University of Leyden Edsger Dijkstra decided that he would major in Theoretical Physics. To develop a good, strong and firm foundation in Theoretical Physics Dijkstra began his studies in mathematics and physics. Douwe Wybe Dijkstra being the loving and supportive father that Edsger needed him to be, was always searching for great opportunities to encourage his son in the field of study that he had chosen. Well, as the story has it, Douwe, (Edsger father) was reading a paper and just happened to come a cross an advertisement for a computer programming course that would be held at Cambridge University in England. The computer programming course was three weeks long. The three week course was to start...

...German-born American theoretical physicist, Albert Einstein, often regarded as the father of modern physics, had exceptional intellectual ability and unprecedented insight. Many believed him to be one of the most influential people in both science and mathematics, and quite possibly the most famous scientist of the 20th century (Severance, 1999). As cited by Fingon and Fingon, Einstein was well known for being a brilliant physicist and abstract thinker, applying his creativity and imagination in his scientific thought process (Parker, 2003). He received the 1921 Nobel Prize for his contribution to the study of physics, namely his special (1905) and general (1916) theories of relativity. The name “Einstein” is often thought of as being synonymous with the word genius. Einstein was not always thought of as a genius, however. His unique intellectual abilities as a young boy created challenges for him in his everyday home and school life, but his sense of wonder paired with persistence and determination led him to be the successful prodigy people know him as today. Abraham Maslow’s humanistic approach of self-actualization provides significant explanation for Einstein’s behaviors and achievements throughout his life. Heredity and environment played vital roles in Einstein’s psychological development. Einstein’s parents and teachers observed his early childhood developmental delays and had doubts regarding his intelligence. His parents worried about his intellectual development...

...Albert Einstein is regarded as the father of modern physics. He was born on march 14 1879 Ulm, in the Kingdom of Wurttemberg in the German Empire. In his early life he studied calculus and philosophy and discovered different formulas which basically changed this world. He was basically German born theoretical physicist who developed the general theory of relativity. As a result of this achievement he is regarded as the father of modern physics and the most influential physicist of the 20th century. Albert Einstein in fact changed the scientific world with his achievement when he gave the idea of E=mc2. In this formula that clearly described that the energy and mass (the ability to do work and the stuff to do work with) were absolutely the same thing. When Newton said that time and space are absolute which means that time flowed in a constant manner. Time is independent of location and remain same for everyone. This idea of Newton was remained unchallenged until Einstein came along. He decided to do experimentation with that and then he theorized that time and space were relative, and in this way he proved that Newton was wrong. With his theory of relativity,Einstein tore apart the idea of time as a constant. I would like to mention there that Einstein published more than 300 scientific papers along with this 150 non-scientific works. He was so intelligent that he made the word "Einstein" synonymous with genius. At the end I would like to mention that Albert Einstein, once...

We are just so different that if we did not have the same blood, I would think that we were not sisters. We are the total opposite of each other. We are not just different physically; we are also different in personality. We think differently. We have different types of hobbies. We enjoy different things. In other words, we are just two different types of person that apparently do not have anything in common. My sister name is Aracely. She is younger than me by four years. She is white and tall. She is the kind of person that is always in a bad mood. She gets mad really fast and sometimes for nothing. It is lie she is happy being mad. I don’t know why she is like that; to me she is just weird. My sister is the girl that always wants to be alone. She doesn’t care for going out or making plans for the weekend with her friends. She prefers to be in our room alone without being bothered. I am the opposite from her. I am older than her but I actually look younger than her. Physically I’m morena, and short. I am the kind of person that is always happy and laughing about everything. I do not like to be alone; I am not used to it.

...The Metaphor Revolution PHL/251 The Metaphor Revolution What is a metaphor? “A metaphor is a figure of speech in which a term or phrase is applied to something to which it is not literally applicable in order to suggest a resemblance.” http://dictionary.reference.com/browse/metaphor A brief history of metaphor go “from Aristotle through speech act theories, metaphor had been viewed as a secondary type of language.” (Black, 1955) “Modern European languages have a large number of metaphors which represent the whole of nature. Many of these, such as Mother Nature, the celestial harmony, the great chain of being, and the book of nature, are used in natural science and in literature. Most of these words can be traced back into prehistory where they arose mythologically from the same small set of images. Metaphors have a powerful influence on the framing of scientific hypothesis making, and so these words have guided the history of natural science, for good or ill, for several millennia. Newtonian mechanics, for example was motivated by the idea of celestial harmony, whereas Darwin used the images of the great chain of being and Mother Nature, and James Hutton created modern geology and ecology by mixing the images of nature as the macrocosm, and as a machine.” (Norwick, 2006) Group A critiqued each others metaphors written in Week 2. We started processing each ones metaphors and their significance and came up with the following. Connie reviewed Rachel’s metaphors...

...civilizations such as the Babylonians, Greeks, Chinese, Indians, Iranians and Maya performed methodical observations of the night sky. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars, but professional astronomy is nowadays often considered to be synonymous with astrophysics.[2]During the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, which is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the observational results and observations being used to confirm theoretical results.Amateur astronomers have contributed to many important astronomical discoveries, and astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient...
