Sigo leyendo a Arnold Sommerfeld (1868-1951). Esta vez su "Wave-Mechanics" que mencioné en Arnold Sommerfeld sobre Atomos y Espectro como continuación de su clásico "Atom Structure and Line Spectra". Esa continuación sólo apareció con las nuevas ediciones: la primera fue publicada en 1919 donde todavía no se había desarrollado la mecánica cuántica. Es interesante leer:

I have called this volume a "wave-mechanical" supplement, becauSe for practical manipulation Schrödinger's methods are obviously superior to the specifics,lly U quantum-mechanical" methods.. On the other hand, however, I have left no doubt :hat the general ideas that have led Heisenberg to, enunciate quantum-mecbanics . are also indispensable for the elaboration of wave-mechanics. The original standpoint of Schrödinger, that transitions are to occur only between co-existing states, is clearly too narrow and does not accurately fit the facts. I have therefore taken over into wave-mechanics the equal treatment of states and transitions, -as is done by Heisenberg from the very beginning, - in particular in deriving the frequency-condition and the rules of polarisation and, intensity in section 5, chapter I. This, of course, denotes that I am renouncing the more definite wave-kinematic objective, set up by Schrödinger and de Broglie, and am sacrificing pictorial representatiqn to formalism. In wave-mechanics the electron still remains a point-charge ultimately, and the light- quantum a point-like centre of energy. But the dualism between the light-quantum and the light-wave extends into the corpuscular region; beside the electron-corpuscle we have the electron-wave with all the accumulative experimental evidence to confirm it.

Digo, interesante que haya preferido a la descripción de Schrödinger pero reconociendo las limitaciones que tiene (muy asociada a electrones ligados) con respecto a la de Heisenberg. Habría que esperar a Dirac para ver la equivalencia de ambos desarrollos.

Nos leemos!
