He believed that scientific theories are free creations of a finely tuned physical intuitions and that the basis on which they are based can t be connected with experiments. He thought that a “good theory” then was one with the least number of postulates. This, in one way, was what made it hard for others to understand his work. Some people did believe in Einstein s work. One of the main people that supported him was a German physicist named Max Planck. Einstein kept his job at the patent office for years after he was discovering these things. In 1911 he moved to a German speaking university at Prague, and in 1912 he returned to the Swiss National Polytechnic in Zurich. Then in 1913 he was appointed director of the Kaiser Wilhelm Institute for physics in Berlin, Germany. Even

before left the patent office in 1907, his work was continuing on his general relativity theory to all coordinate systems. He began to think of this theory with reference points. For an example, people in a moving elevator can t decide whether the force that acts on them is caused by a gravitation or the constant acting on the elevator. Albert Einstein s full general theory of relativity wasn t publish till late in 1916. In this theory the interaction of bodies (stars or solar systems), which had been given to gravitational forces, are explained as the influences of the bodies on space-time. On the basis of the general theory of relativity, Einstein accounted for the variations in the orbital motion of the planets and the predicted the bending of the starlight in the vicinity of

the massive body as the sun. The confirmation of this latter phenomenon during an eclipse of the sun in 1919 became a media event, and Einstein s fame spread worldwide. For the rest of Einstein s life, he devoted a considerable time generalizing his theory even more. His last effort, the unified field theory, which was not extremely entirely successful, was an attempt to understand all physical interactions including electromagnetic interactions and weak and strong interactions. This intern, modified the geometry of space-time between interacting entities. Most of Einstein s colleagues thought that these new efforts were misguided. Between 1915 and 1930 the mainstream of physics was in developing a new conception of the fundamental charter matter, known as quantum theory. This

theory contained the feature of wave-particle duality that Einstein had earlier urged as necessary, as well as the uncertainty principle, which says that the precision in measuring process is limited. Additionally, it contained a novel rejection at a fundamental level, of the notion of strict causality. Einstein, however, would not accepted such notions and remained a critic of these developments until the end of his life. “God,” Einstein once said, “does not play dice with the world.” After 1919, Einstein became internationally renewed. During World War I when Hitler came to power he decided to move to USA. He took a position at the Institute for Advanced Study at Princeton, New Jersey. In 1913 Einstein collaborated with several other physicists in writing a letter to

President Franklin Roosevelt, pointing out the possibility of making an atomic bomb and the likelihood that the German government was embarking on such a course. The letter, which bore only Einstein s signature, help lend urgency to efforts in the U. S. to build the atomic bomb, but Einstein himself played no role in the work and knew nothing about it at the time. After the war, Einstein was active in the cause of international disarmament and world government. Einstein died in Princeton on April 18, 1955.
