Who was Albert Einstein?

Answer 1

Albert Einstein is possibly the most famous scientist who ever lived! He was a theoretical physicist and mathematician, and a genius. One of his better known achievements was the mass-energy equivalence equation: E = mc2. Einstein developed the theory of relativity and he won the Nobel Prize in Physics in 1921 for his work on the photoelectric effect.

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 born on March 14, 1879, in Ulm, Württemberg, Germany. He later renounced his German citizenship, and became a Swiss citizen in 1901. In 1900, Einstein attained a degree in physics at ETH Zürich -- the Swiss Federal Institute of Technology (FIT) in Zurich. He received a doctorate from the University of Zürich in 1905. Einstein married Mileva Marić in 1903 and later divorced her. They had three children (two sons and a daughter). In 1919, he married his cousin Elsa Löwenthal.

Einstein fled Germany in 1933 to escape the Nazis because he was a pacifist and a Jew. He became a US citizen in 1940. Einstein died on April 18, 1955 (aged 76), in Princeton, New Jersey, US.

Answer 2

Albert Einstein was a physicist born in the German Empire in 1879. He was famous for his ideas about relativity and E=mc^2. He also thought that Sir Isaac Newton's ideas of gravity weren't completely correct. Because of this, he received the 1921 Nobel Prize in physics.
