Ya alguna vez mencioné este tema, comentando otro escrito de Dirac: cuando desarrolló la llamada ecuación de Dirac, que le resultó tan hermosa, que no se tomó el trabajo de ver si, aplicándola, se podía explicar el espectro del átomo de hidrógeno. Podía tomar el camino del desarrollo exacto de las consecuencias de su ecuación. Pero dejó ese trabajo a otros, notablemente a Darwin (creo que era nieto del Darwin más conocido, Charles). Comenta sobre el tema Dirac en una entrevista que le hace T.S.Kuhn en 1963:

DIRAC:
When I first got that equation, of course I was very anxious to know whether it would work for the hydrogen atom, and I just tried it by an approximation method. I thought that if I got it anywhere near right with an approximation method, I would be very happy about that. It needed someone else, namely Darwin (and Gordon), to tackle that equation as an exact equation and see what the exact solutions were; I think I would have been too scared myself to consider it exactly. I would be too scared that il would get unfortunate results which would compel the whole theory to be abandoned.

T. s. KUHN:
That"s fascinating; does this mean that you had yourself not tried to handle exactly before going to an approximation method?

DIRAC:
That is so, yes.

KUHN:
You looked for the approximation method from the start?

DIRAC:
Yes, yes. Of course 1 had the fear that the whole theory was nowhere near right, and if 1 could get it approximately right, well my confidence would already be substantially increased in that way. It"s just that one has a lack of confidence when one introduces something quite new.

Aún el gran Dirac necesitaba ganar confianza antes de encarar todas las consecuencias de su famosa ecuación.

Nos leemos!
