What profession does Action at a distance and Albert Einstein have in common?
Albert Einstein Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist. Einstein developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). Einstein's work is also known for its influence on the philosophy of science. Einstein is best known by the general public for his mass–energy equivalence formula "E" = "mc" (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 evolution of quantum theory.
Paul Harzer Paul Harzer (1857–1932) was a mathematician and astronomer best known for his papers arguing with Albert Einstein regarding the Sagnac effect and its relationship to Special Relativity. Harzer was Professor of Astronomy at the University of Kiel and Director of its observatory. His published article on the experiment of Franz Harress drew two reply articles from Einstein.
