Einstein is most well-known for his theory of relativity (e=mc²), but did you know these lesser-known facts about everyone's favorite crazy-haired physicist?

Albert Einstein is one of the most well-known physicists throughout history. Among other things, he is also known for formulating the world-famous equation E=mc², the equation that relates that energy and mass as not separate, but rather a single entity. This equation opened doors to numerous scientific advances.

Albert Einstein's birthdate was less than a week ago, on March 14, in the year 1879. Happy belated birthday, Albert!
