London: Harrison & Sons, 1927. 1st Edition. 1927 omputation of the coefficient of spontaneous emission of an atom (Wikipedia). He "supplied a systematic procedure for transferring the characteristic quantum phenomenon of discreteness of physical quantities from the quantum mechanical treatment of particles to a corresponding treatment of field. Employing the quantum mechanical theory of the harmonic oscillator, Dirac gave a theoretical description of how photons appear in the quantization of the electromagnetic radiation field. Later, Dirac's procedure became a model for the quantization of other fields as well" (Stanford website). Item #347
