Princess Diana
Diana was referred to by her friends and family as “Lady Diana Spencer” before she was made the Princess of Wales. Despite coming from an affluent and aristocratic family, she taught kindergarten and shared a flat in London with her friends, where photographers took this picture in December 1980.
Albert Einstein
One of the best and most influential physicists of all time, Albert Einstein was a theoretical physicist who was born in Germany. The theory of relativity is what Einstein is most famous for, although he also made significant contributions to the theory of quantum mechanics. Together, relativity and quantum mechanics form the foundation of contemporary physics. The relativity theory-derived mass-energy equivalence formula he developed, E = mc2, has been labeled “the world’s most famous equation”.
