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.'}
