Happy birthday, Albert Einstein!
One of history's most celebrated thinkers would have turned 134 today.
His numerous contributions to physics include the special and general theories of relativity, mass-energy equivalence, the theory of photons, and many other topics. He received the 1921 Nobel Prize in Physics for his contributions.
Einstein was born in Ulm, Germany, on March 14, 1879, and died on April 18, 1955 in Princeton, New Jersey, where his brain was removed for study and considered lost for many years. Researchers later recovered images and specimens of Einstein's brain, which are housed in museums around the world and have been studied for clues to Einstein's genius.
