Albert Einstein is known all over the world as a brilliant theoretical physicist and the founder of the theory of relativity. He is perhaps the greatest scientist of the 20th century. Some of his ideas made possible the atomic bomb, as well as television and other inventions.
He was born in 1879 in a small German town. The Einstein family 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.
After graduating from the college, Einstein started to work at the Swiss Patent Office in Bern.
In 1905 he wrote a short 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 = me2), the basis of atomic energy.
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'.
