Albert Einstein

Albert Einstein is one of the most famous scientists that has ever lived. During his time, he was an international celebrity with great influence. Like Isaac Newton before him, Einstein profoundly changed our understanding of the world with his theories of how the universe is structured. His Theory of Relativity -- which put forth new ways to measure time and space -- affected nearly every field of science. Einstein also made major breakthroughs in the field of quantum mechanics, which deals with sub-atomic particles such as electrons, protons, and neutrons. His work in this area eventually led to the creation and utilization of the first atomic bomb.
