Albert Einstein

Albert Einstein ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).

​

When Albert was young, his parents thought he was mentally challenged. His grades in school were so poor that a teacher asked his to quit, saying "Einstein you will never amount to anything in life!"

​

Einstein failed the entrance exam to Swiss Polytechnic Institute. His work is also known for its influence on the philosophy of science. He is best known to the general public 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", a pivotal step in the development of quantum theory.
