Giants of Science/gigantes de Ci

Albert Einstein was one of the most famous scientists in the world. He once said that his mind was his laboratory and he was, in fact, able to work through processes in his head that others had to work out on paper. In his theory of relativity, he explained the relationship between space and time. His study of mass and energy ultimately led to the atomic bomb. His work with photoelectric effect eventually led to the development of television, the laser, and photocells in security systems.
