“Einstein has a feeling for the central order of things. He can detect it in the simplicity of natural laws. We may take it that he felt this simplicity very strongly and directly during his discovery of the theory of relativity. Admittedly, this is a far cry from the contents of religion. I don't believe Einstein is tied to any religious tradition, and I rather think the idea of a personal God is entirely foreign to him.”

“Es gibt keinen Gott und Dirac ist sein Prophet. (There is no God and Dirac is his Prophet.){A remark made during the Fifth Solvay International Conference (October 1927), after a discussion of the religious views of various physicists, at which all the participants laughed, including Dirac, as quoted in Teil und das Ganze (1969), by Werner Heisenberg, p. 119; it is an ironic play on the Muslim statement of faith, the Shahada, often translated: 'There is no god but Allah, and Muhammad is his Prophet.'}”

“Our friend Dirac has a creed; and the main tenet of that creed is: There is no God, and Dirac is his prophet.”

“I do not mind if you think slowly, but I do object when you publish more quickly than you think.”

“It would be most satisfactory if physics and psyche could be seen as complementary aspects of the same reality”

“This isn't right. This isn't even wrong.”

“I heard that in relativity theory, space and time are the same thing. Einstein discovered this when he kept showing up three miles late for his meetings.”
