Albert Einstein 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the general theory of relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics and the most influential physicist of the 20th century. While 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 within physics.
Einstein published more than 300 scientific papers along with over 150 non-scientific works
This later became known as Einstein's special theory of relativity.
Einstein was greatest man for science. And he was very kind.
