Albert Einstein - Biography

Albert Einstein was born in Germany in 1879. He enjoyed classical music and played the violin. One story Einstein liked to tell about his childhood was of a wonder he saw when he was four or five years old: a magnetic compass. The needle's invariable northward swing, guided by an invisible force, profoundly impressed the child. The compass convinced him that there had to be "something behind things, something deeply hidden."
Even as a small boy Albert Einstein was self-sufficient and thoughtful. According to family legend he was a slow talker, pausing to consider what he would say. His sister remembered the concentration and perseverance with which he would build houses of cards.
Albert Einstein's first job was that of patent clerk.
The Atomic Bomb
Please don't build one at home. On August 2nd 1939, just before the beginning of World War II, Einstein wrote to then President Franklin D. Roosevelt. Einstein and several other scientists told Roosevelt of efforts in Nazi Germany to purify U-235 with which might in turn be used to build an atomic bomb. It was shortly thereafter that the United States Government began the serious undertaking known only then as the Manhattan Project. Simply put, the Manhattan Project was committed to expedient research and production that would produce a viable atomic bomb. [The Letter]

Albert Einstein in Princeton
"Albert Einstein (1879 - 1955) first gained worldwide prominence in 1919, when British astronomers verified predictions of Einstein's general theory of relativity through measurements taken during a total eclipse. Einstein's theories expanded upon, and in some cases refuted, universal laws formulated by Newton in the late seventeenth century."lbert Einstein was asked to pose so many times that he said if he hadn't been a physicist, he could have made a living as a model.

Inventor and innovations surrounding nuclear physics.
E = MC2
Albert Einstein developed a theory about the relationship of mass and energy. The formula, E=mc[2], is probably the most famous outcome from Einstein's special theory of relativity. The formula says energy (E) equals mass (m) times the speed of light (c) squared. In essence, it means mass is just one form of energy. Since the speed of light squared is an enormous number (186,000 miles per second)[2], a small amount of mass can be converted to a phenomenal amount of energy. Or, if there's a lot of energy available, some energy can be converted to mass and a new particle can be created. Nuclear reactors, for instance, work because nuclear reactions convert small amounts of mass into large amounts of energy.
