  • Einstein, Albert (2003). "Physics and Reality" (PDF). Daedalus. 132 (4): 24. doi:10.1162/001152603771338742. S2CID 57559543. Archived from the original (PDF) on 2012-04-15. The question is first: How can one assign a discrete succession of energy values Hσ to a system specified in the sense of classical mechanics (the energy function is a given function of the coordinates qr and the corresponding momenta pr)? The Planck constant h relates the frequency Hσ/h to the energy values Hσ. It is therefore sufficient to give to the system a succession of discrete frequency values.
