The theory of relativity is based around the principle of physics. Albert Einstein conceived the idea with the help from a few other physicists. The theory is split into two main ideas, the special theory and the general theory. The theories combined led to Isaac Newton's theory of gravitation. The special and general theory, and Albert Einstein, effected science and the way we live our lives today. In 1905, Einstein published the special theory and in 1915, his general theory. His accomplishments could possible make him the most influential man of modern history. One word to describe the way he thought would be "genius." Einstein created new branches of study in physics and astronomy, but nothing compares to how he impacted our daily lives. This is proven by the Global Positioning System (GPS) satellites surrounding the earth. Even modern physicists today are more aware of aspects of the universe. Einstein shot down Newton's idea that every object attracts every other object in direct proportion to its mass. Einstein said that the world line of every object is a short distance between two points in a continuum. This made Einstein's general theory of relativity a seperate theory about a differentn topic-the effects of gravity. The general theory was created to explain conflicts between the laws of relativtiy and the law of gravity. He came up with a solution, equivalence. Einstein's theories of relativity have affected our daily lives in such basic ways. Such as how we heat our homes, reach our destinations, and measure our days. It also has an effect on philosophers, polititans, and activists. Relativity was a leading cause in post modernism and philosophic relativism. In pre-relativiy, philopsohers such as Aristotle, argued the way of approaching aspects of life. Knowledge is power and that is what made Einstein, a child of immagrants, Jewish and poor, a success. Another achievement was opening a new viewpoint to diversity, which the world was not yet exposed too. Einstein was a brillant physicist and a man who changed the world in ways we couldn't imagine. His work on relativity not only impacted science but our society as well. He will never be forgotten and either will his work. With the help of Einstein and other physicist, our lives can be made easy and understandable. Einstein help us explain many of the underlying mysteries of our time.

Einstein's idea about special relativity includes electricty and magnetism. In conclusion, time dialation, length contraction and E=mc squared have changed our outlook on time and space, matter and energy. The site has different modules used to give an overview on the theory of relativity. With video clips and other animations, anyone interested in his theory would love to encounter this site. Every aspect of relativity is listed with unbias information that is backed with multiple other links. If you want to learn more check out the root site, which is an australian university that specializes in physics.

Albert Einstein wrote this book in 1920 with the help of a theoretical physicist, L. Boltzmann, who simply added valuable additions. It was written to give an exact insight on the theory of relativity. Einstein's main ideas are shown in the most simple and intelligible form that are listed in the order they originated from. His work is categorized in three parts, with the third being extra considerations on the world as a whole. The information is backed with an index to all of the English references used. If anything wasn't covered the index is a good tool to use to find additional information on the theory of relativity. Works Cited Lawson, Robert. "Einstein, Albert. 1920.
