Style tips and a question edit

And a couple of suggestions and remarks. First is that one should write ==See also== instead of ==See Also==, that's the house rule. :) Second is that one should use an edit summary when contributing. Small thing, but helpful. :)

Thank you for the new picture at continuous spectrum. And I have a question. Does the spectrum of light indeed have anything to do with the spectrum of an operator? Or with the spectrum of a hydrogen atom? If so, it would be nice to clarify that in the article on continuous spectrum. I am a mathematician, and I can't tell these things. Thanks, and you can reply here, I will keep your talk page on my watchlist. Oleg Alexandrov (talk) 23:09, 27 January 2006 (UTC)Reply
