Albert Einstein is considered one of the greatest and most popular scientists of all time. Three papers he published in 1905 were pivotal in the development of physics and, to a large degree, Western thought. These papers discussed the quantum nature of light, provided a description of molecular motion, and introduced the special theory of relativity. Einstein was famous for continually reexamining traditional scientific assumptions and coming to straightforward, elegant conclusions no one else had reached. He is less famous for his social involvement, although he was a staunch supporter of both pacifism and Zionism. Here, Einstein discusses Gandhi and commends nonviolence.
