Who was Albert Einstein and what did he do?

His contributions amounted to a radical change in world view. Before Einstein, certain things were simply assumed to be true. Among them were the "laws" gravity and falling bodies as they had been outlined by Isaac Newton. Also, it was generally believed that 'time' itself was a physical constant: Everyone and everything would experience the passage of time the same way as everyone and everything else. His theory of special relativity predicted that this was not true, and was later validated by experiments with atomic clocks.

Einstein's work shows that while Newton's equations work for moving objects that are part of our observed world, including the planets, the concepts of velocity, gravity and time work much differently when you are dealing with the speed of light. Mass and time change in amazing ways when objects approach the speed of light.

Albert Einstein was a German inventor and mathematic who invented the formula E=mc2.

He was a genius, physicist and a mathematician back in the time of WWII. He fled from Germany to escape the Nazis because he was a pacifist and a Jew. He has also won a few Nobel Prizes. He is dead now but most of the things we know about light and the theory of relativity came form him.

He was a German-born theoretical physicist. He is best known for his theory of relativity and specifically the mass-energy equivalence. He has received a Nobel Prize.
