English theoretical physicist who applied relativity theory to quantum mechanics and predicted the existence of antimatter and the positron (1902-1984)
Source: WordNetIn his 1930 book, Dirac took for granted that measurements could be made, but was very vague about what was actually involved. Willis Lamb
Neither Dirac nor von Neumann discussed his measurements in physical terms. Willis Lamb
There is no God and Dirac is his Prophet. Wolfgang Pauli
The Dirac notation, though originally applied to the propagation of single particles, also applies to describing the propagation of ensembles of coherent, or indistinguishable, photons. F. J. Duarte
Regardless of the prophetic value of Dirac's description [on interference] his was probably the first discussion... including a coherent beam of light. In other words, Dirac wrote the first chapter in laser optics. F. J. Duarte
If I understand Dirac correctly, his meaning is this: there is no God, and Dirac is his Prophet. Wolfgang Pauli
