372:. The question would seem to me to be whether there would be the political will to provide an article on the Dirac equation that could be handled by bright pre-college types or other people with an interest in physics but without at least a couple years as a physics major or a math major. The unsigned message above is correct, I believe, in asserting that the prominence assumed by 551:
into Planck constant. To do so seems reasonable. However, Aymatth2 has brought up the idea that Dirac's constant, i.e., conceptualizing the quantum character of things in a new way, had some (at a minimum) heuristic effect in regard to the development of the Dirac equation. If that understanding can

I have to go back to the macro world of angular momentum as it applies to diverting the courses of large athletic or angry bodies, so until I get caught up on the mental/spiritual world, or the "zone" of, martial artists I'm afraid I won't be much help. (Fortunately I only have to think about it at

Investigating the history of the thought processes by which Dirac made his equations might well help some students understand the significance of the math in Dirac's work. But just take a look at the Dirac equation article and tell me where 15-20k of popularized physics and historical background

Since you had the insight, you may be able to recover it by looking at what he wrote. The insight that h-bar encodes is that the angular velocity of an electron (in whatever sense an electron can have velocity) is quantized. Angular momentum, spin, etc., all mean something, and what we see on a

article should say what is meant by the "reduced Planck's constant". I am very rusty indeed on this subject, but I seem to remember that Dirac's introduction of the new symbol was a bit more than just an algebraic shorthand - it expressed an intuitive insight. Is that covered in the article on
451:
classical scale may be built on these more fundamental phenomena. The key thing that Dirac did, as I understand it, was to create a model that could produce a particle-appropriate answer if asked one kind of question and a wave-like answer if asked a wavey question.
172: 299:, on further reflection I agree that it would be preferable to delete this article rather than leave it as a pointless redirect. Responding to points above, the article doesn't have any history, it was split off from 51:. There is a consensus that this should be merged somewhere. Planck constant seems ok. Fixing the redirects and editing articles is on the other hand not something that would be discussed at AfD so I am closing this. 414:
I don't know if Dirac himself used the term "Dirac's constant" - probably not. But I have a vague memory of attending a lecture he gave in the late 1960s and getting one of those "Ah-ha" moments when he introduced
