Biography and s cientific career Albert Einstein is known all other the world as a brilliant theoretical physicist and the founder of the theory of relativity. He is perhaps the greatest scientist of the 20 th century. Some of his ideas made possible the atomic bomb, as well as television and other great inventions. He was born in 1879 in a small German town. The Einsteins soon moved to Munich, where Albert went to school. Neither his parents, nor his school teachers thought much of his mental abilities. His uncle often joked: ”Not everybody is born to become a professor.” In 1895 Albert failed the entrance examination to a technical college in Zurich. A year later, however, he managed to pass the exam and entered the college. Albert Einstein in 1893 (age 14)

Albert Einstein in 1904 After graduating from the college, Einstein started to work at the Swiss Patene Office in Bern. In 1905 he wrote a shot article in a science magazine. This was his “Special Theory of Relativity”, which gave the world the most famous equation relating mass and energy E=mc ², the basis of atomic energy. In his paper on mass–energy equivalence Einstein produced E = mc ² from his special relativity equations. Einstein's 1905 work on relativity remained controversial for many years, but was accepted by leading physicists, starting with Max Planck. Later, he became a professor in several European universities and in 1914 moved to Berlin as a member of the Prussian Academy of Sciences. After ten years of hard work he created his “General Theory of Relativity ”.

The theory of quanta was either pivotal to, or gave rise to, quantum theory. On the Motion of Small Particles Suspended in a Stationary Liquid, as Required by the Molecular Kinetic Theory of Heat Brownian motion 11 May 18 July Empirical evidence for the atom, substantial support to the novel area of statistical physics. Does the Inertia of a Body Depend Upon Its Energy Content? Matter–energy equivalence 27 Sept 21 Nov Equivalence of matter and energy, E = mc2 (and by implication, the ability of gravity—and matter generally—to "bend" light), the existence of "rest energy", and the basis of nuclear energy (the conversion of matter to energy by humans and in the cosmos).

Einstein's official 1921 portrait after receiving the Nobel Prize in Physics. In 1921 Einstein received the Nobel Prize for Physics. A Jew, and a pacifist, he was attacked by the nazis, and when Hitler came to power in 1933 he decided to settle in the United States. In 1939 Albert Einstein wrote a letter to president Roosevelt, at the request of several prominent physicists, outlining the military potential of nuclear energy and the dangers of a Nazi lead in this field. His letter greatly influenced the decision to build an atomic bomb , though he took no part in the Manhattan Project. After the war he spoke out passionately against nuclear weapons and repression.

Einstein died in 1955. The artificial element einsteinium has been named in his honour.
