Sorry, if you cool down carbon atoms, they form a solid, not a Bose Einsein condensate. Even if you take atoms that can do that, only paired system are condensed, the individual atoms are not, they are a different quantum system. <snip> >It's more complex than that.

The square root of the probability is simply the wave amplitude, so what you say is that what is waving is the wave. Nothing is "waving", wave is simply an outdated way to represent some properties of the dual vector space of differential forms. In euclidean space that dual space maps on the vector space, so we can build systems working with particle and other using "waves" in the same space. The classical example is the Young's slits experiment. The slits work in the form space and the screen behind in the vector space. Bad vulgarization books write about the dual nature of particles and wave, in fact the system is simply built over two spaces! (a nice trick for a circus clown as Young, by the way he was too a GP). > >I suggest you look at an elementary differential geometry book to > >get some familliarity with these concepts. > >Thanks for the advice but I don't believe I need to do that. I think you need badly that reading :-) A good book to see, with plenty of drawings is the track one of: Gravitation by Missner, Thorn and Wheeler, edited by W.H.Freeman. Yvan Bozzonetti.
