The theory of relativity is accepted amongst society by the technology we use in everyday life. Relativity is backed up by numerous ways. Devices such as GPSs and radars, mathematical equations, and common perceptions of how we see things as "moving" or "standing still." Today, a large part of the population uses Einstein's work without even acknowledging it. Einstein's theory itself "literally and figuratively revolutionized our world." (Arya). In 1905, Albert Einstein proposed the priniple of relativity, which stated that any object at a constant motion was undetectable. This was the further study of the 19th century's law of electricity and magnetism, which meant that light was a phenomenon, or an electromagnetic wave that could distiguish between frames of motion. But this was hard to study, since scientists didn't have cold turkey facts. Were the effects really there? Once this frame of reference was tested over and over, failing every time, the theory of relativity was developed. And in this priniple, frames of reference were used, such as when they were moving or accelerating. In the early stages of the theory of general relativity, motions in a circle were described to have centripetal force. "That is a force towards the center of rotation, of magnitude where R is the radius of the circle of rotation and V is the velocity of motion around it." (Stern).

Fcentripetal = mV 2/R

In another piece of Einstein's puzzle, there exists a different kind of force, but is used in the same type of example. Centrifugal force, which is found in the rotating frames of references, helps move the theory of relativity along.

The Cetrifugal forces help keep passengers inside the car.

Relativity itself is used in everyday lives. Common devices such as GPSs and radar use the "frame of motion" in order to find other objects. In the theory of relativity, the basic principle that objects are attracted to one another is used, and every one of those objects is in reference to something else. GPSs, for example, give the driver landmarks and signals in reference to other objects in order to give proper directions.

The theory of relativity, among other conclusions, provided many mathematical eqations for our world today. We use these equations to help gather the information needed to form the simple frames of references. We can now find numbers of energy, momentum, gammas, and the speed of light is even a number. Energy, or E=mc^2, is defined with the "m" (mass) sitting at rest. Momentum, or p=mv, is dealing with the mass in motion. And gammas have in the equation a "c" which is the speed of light and "v" the "object in question" (SLAC 1). All of these equations are finding objects in motion or at rest, but either way one puts it, those objects are in reference to other things. //v// is the speed of the object in question ||

Common perceptions play a big part in life, but are not looked at as "in accordance to Einstein's theory of general relativity." People in cars, objects in falling motions, and people and objects in passing are all examples of their own frame of reference to each other. Such as a train moving past a train station. To bystanders resting at the station, the train is moving. But in the perception of passengers aboard the train, the bystanders are moving. It's a simple frame of reference concept that is of the object's own position. Neither party is right or wrong when saying "the people are moving" or "the train is moving." To the passengers, others on the train might not be moving, but then agian they may be, being aboard a "moving" train. Then the bystanders, who are in their eyes resting, but to the train's boarders moving. Frame of reference in the space time continum is all around us.

In conclusion, Einstein's theory of relativity is accepted amongst this world because of the technology we possess, the equations we use, and the perceptions that we all share. It's easy to say that all scientist agree, when in reality that isn't true. But most scientists and researchers believe that the theory of relativity is an arguement worth pursuing and testing numerous times because the basics of it simply make sense. The space time continum in which we exist is hard enough to grasp, but with the right words and tests, we can figure out exactly what Einstein was trying to tell us.

BIBLIOGRAPHIES AND ANNOTATIONS Arya, Atam, Arthur Beiser, Ronald Gautreau, and William Savin. "Einstein's Speical Relativity for the Layman." __Modern Physics__. 27 Jan. 2009 http://74.125.47.132/search?q=cache:Xvq4NNITVhgJ:photo.kathimerini.gr/xtra/files/Meletes/doc/Mel2209063.doc+EINSTEIN%E2%80%99S+SPECIAL+RELATIVITY+FOR+THE+LAYMAN&hl=en&ct=clnk&cd=1&gl=us>. This cite was very useful because is gave pieces of Einstein's theory little by little. Arya, along with the other authors, fully backed the theory up, and aided the reader with helpful examples and equations. This cite was extremely up to date with facts and information on the theory of general relativity, and was a valid and reliable source.

Raiter, Brian. "Short Words to Explain Relativity." __Welcome to Muppetlabs__. 27 Jan. 2009 http://www.muppetlabs.com/~breadbox/txt/al.html>. This cite is a valid source for anyone trying to find a little information about the theory of relativity. Although it uses four-lettered-words or less, that makes it rather easy for a common person (with no knowledge on this topic) to understand the broad subject of Einstein's work. Raiter found it necessary to explain relativity in such a manner because he felt that would make it easier for everyone.

Stern, Dr. David. "The Theory of Relativity." __Educational Web Sites on Astronomy,__. 20 Feb. 2008. 27 Jan. 2009 http://www-istp.gsfc.nasa.gov/stargaze/Srelativ.htm>. This website was very very helpful by use of everyday examples. It was up to date with it's equations and facts, and had many parts to the website, which helped the reader get a better understanding of the many parts of the broad topic. It was quite credible, and by having the many examples of everyday lives, such as rollercoasters, it made the reader understand the physics in an easier way.

"Theory: Special Relativity (SLAC VVC)." __SLAC Public Website Server__. 31 Oct. 2008. 26 Jan. 2009 http://www2.slac.stanford.edu/vvc/theory/relativity.html>. This cite is very credible, and useful when trying to find the basics and depths of Einstein's work. It has information for readers just starting to learn about relativity, but it also uses equations and references for readers on a higher level of knowledge. By having both, I found that it was a very useful website. It also infcluded the steps one will have to take in order to gain the information. Each equation builds on one another, and the website did just that, which is a great learning tactic.

Weisstein, Eric. "Speical Relativity." __Science World__. 27 Jan. 2009 [|http://scienceworld.wolfram]>. This website was very informative with no opinions or bias to be found. Many examples of equations were given, to explain the theory to readers. It was highly up to date and factual. Also, many other links and sources can be found on this site, leading to other credible sources that the author used to find his results. I also found this useful when I was first trying to gather information about the theory of general and special relativity.
