Albert Einstein was a German-born theoretical physicist. He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). He is best known for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"). He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". The latter was pivotal in establishing quantum theory. The original Genius has a new equation — or, simply, a new look! Our best-selling Genius Series print, Albert, has been refreshed! Featuring its popular black and white chalkboard design, this print is now decorated with a few new sketches including Baby Einstein, building blocks, and other illustrations that pay homage to Albert's accomplishments and legacy. Albert also incorporates the famous "I'm a Genius" quote and E=mc2 equation to inspire and influence your little thinker, just like the original version.
