Einstein's Thoeory of Relativity
Albert Einstein was the child of an immigrant, a Jew and very poor. But, as the story goes, some said that Einstein became rich in a matter of one night, all because of a solar eclipse (Lightman). Later on, his theory of relativity would explain the mystery of space and time taht are still relevant to us today. Einstein first came up with the idea for his theory during the early 20th centuries. He began doing his research based on the classical mechanics of Newton's Law and came to the conclusion that "space and time can be visualized as coordinate systems, or 'reference point,' relative to the observer" ("Introduction"). He finally published his theory in 1905 and was not made public until 1915. Einstein's theory of relativity has had an impact on more than just the field of science. Throughout our day-to-day life, Einstein's theory is present everywhere. Einstein is the one that found the theory of relativity. Source: http://lynx.uio.no/jon/gif/famous/einstein-tongue.jpg 

Einstein's principle is broken down into two main parts: the theory of general relativity and the special theory of relativity. Although the two can be different, the principles that apply to both of them are the same... It doesn't matter where you are. (Principle of translational invariance in space) It doesn't matter when you are. (Principle of translational invariance in time) It doesn't matter how you are oriented. (Principle of rotational invariance) In a simple sense, the two basically fits into the same pattern: All things being the same, “it doesn't matter how fast you're going if you're moving with fixed speed along a straight line (Mermin). Einstein also states that “the law of physics and science are the same for every person, regardless of their speed (Arora). His other famous discovery is the equation //E=MC2,// which works on everything. Source: //http://www.romanoff.com/store/media/einstein-albert.jpg//

Example 1:
Einstein published the theory called general relativity that proposed gravity and motion can affect the intervals of time in space. This theory explain why "a car accelrating frowards feels just lie sideways gravity puching you back against your seat" (Lightman). Or why as an elevator accelerating upward flet like gravity is pushing you into the floor. "The key idea of general relativity," said author Lightman, "is that gravity pulling in one direction is completely equivalent to an acceleration in the opposite direction."

Example 2:
The theory's application to nuclear energy producted lead to the synchronization of GPS, which has a large affect on our day-to-day life more than we care to admit. "Nuclear energy has helped alleviate a portion of our reliance on non-renewable resources for our energy needs... we will be continually drawn towards the promises nuclear energy has already fulfilled for other parts of the world that have more readily accepted it as a mojor energy supplier" (Arora).

Example 3:
His theory of how gravity an motion relate together explain why things, not only on earth but space, works. It also explain why object closer to the sun move more slowly. "A lesser trivial example is provided by the Doppler Effect. If a yellow light moves away from you at an enormous speed, the color you see changes from yellow to red" and if it moves towards you, it changes from yellow to blue (Mermin). In essence the color of the object in a frame of reference can change depend on whether it is moving or at rest and the direction it is moving in. What the relativity principle states is that "if a light is seen to be yellow," it is stationary. And if it moves in a uniform velocity, it is seen as yellow by someone who id moving in the same veloctiy" (Mermin).

Conclusion:
Einstein's discovery of the theory of relativity has brought many answers to the mechanics of our everday lives. With his help, we know know why light travels in the speed it is in, and even how the Big Bang theory came to be. Alexander Friedmann, who used Einstein's equation of general relativity, found that earth, in the beginning, was in a "state of extremely high density and temperature and then expand in time, thinning out an cooling as it did so." By doing so, Friedmann was able to predict that the earth is approximately 10 billion years old (Lightman). A very big accomplishment at the time. The theory of relativity has made a significant impact in our time. It has help scientist under the motion of space and extend the knowledge we have about the Doppler effect. It has also explain the way gravity works, and how we as human begins has been affect by it. Lastly, we would never have developed the GPS, or even any other nuclear devises, without the help of Einstein's numerous theory. And even so, those three are just a small fraction of what Einstein did. He was once a great annovator in his time, and now, a ledgend in ours.

It gave a brief overview of the theory and the affect it has on our universe. It does not include alot of details or in-depth stuff, but is veryy reliable and easy to understend.

Princeton University Press. 27 Jan. 2009. . It gave an overview on Eistein's theory of relativity. It is a very good site to use becasue it talks about some of the infulences that the theory has made on us. It provides only a small chapter of the book, but is very useful. Mostly it is focused on Einstein's theory and not on him.

This site is very good if one want looking to see what and how Einstein's theory has changed us and how it is use in our everyday lives. It includes everyday examples and a explaination of it. It does not include a whole lot of information on the theory itself, but does give a small description of it.

It could be difficuly to understand sometime but is very reliable. The informations are more complex and involve various equations. This site is mostly about the theory of special relativity.

It divides the information into sections and is very carefully presented. It talks about Einstein in detail, follow by his theories. It also relates the finding that result from his theory. The site has many section, and all of them contains numerous informations.
