Why does the page change part-way through from giving quotee after quote to vice-versa? I haven't seen this on any other page, and it confused me rather a lot when I first read it.Olaf Davis 21:09, 28 September 2006 (UTC)

It was because most of the later part of the page was simply copied from an other site, with some changes made to it for here. I've cleaned it all up, so it's consistent throughout. —LrdChaos (talk) 21:34, 28 September 2006 (UTC)

The quote that starts with "The very nature of the quantum theory ..." is from an article in Nature: N. Bohr. The quantum postulate and the recent development of atomic theory. Nature, 121:580–590, 1928. Its on the first page in the right column. Andreas Skielboe 13:53, 15 June 2008 (UTC)

  • The more you see how strangely Nature behaves, the harder it is to make a model that explains how even the simplest phenomena actually work. So theoretical physics has given up on that.
  • God does not play dice with the cosmos.
    • Albert Einstein (several variants exist)(jedenfals bin ich davon überzeugt dass Gott nicht würfelt)
  • Do not presume to tell God what to do.
    • Niels Bohr, In response to Albert Einstein's quote.
  • If that turns out to be true, I'll quit physics.
    • Max von Laue, Nobel Laureate 1914
    • Talking about de Broglie's thesis on electrons having wave properties.
  • Anyone wanting to discuss a quantum mechanical problem had better understand and learn to apply quantum mechanics to that problem.
  • To the electron: may it never be of any use to anybody!
  • Anyone who is not shocked by quantum theory has not understood a single word.
  • The very nature of the quantum theory ... forces us to regard the space-time coordination and the claim of causality, the union of which characterizes the classical theories, as complementary but exclusive features of the description, symbolizing the idealization of observation and description, respectively.
  • There is no quantum world. There is only an abstract physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature.
  • Very interesting theory - it makes no sense at all.
  • I myself only came to believe in the uncertainty relations after many pangs of conscience…
  • Had I known that we were not going to get rid of this damned quantum jumping, I never would have involved myself in this business!
  • One does not get an answer to the question, 'What is the state after collision?' but only to the question, 'How probable is a given effect of the collision?' From the standpoint of our quantum mechanics, there is no quantity which causally fixes the effect of a collision in an individual event. Should we hope to discover such properties later ... and determine [them] in individual events? ... I myself am inclined to renounce determinism in the atomic world, but that is a philosophical question for which physical arguments alone do not set standards.
  • A philosopher once said, 'It is necessary for the very existence of science that the same conditions always produce the same results.' Well, they don't!
  • Marvelous, what ideas the young people have these days. But I don't believe a word of it.
  • Quantum mechanics is very impressive. But an inner voice tells me that it is not yet the real thing. The theory produces a good deal but hardly brings us closer to the secret of the Old One. I am at all events convinced that He does not play dice.
  • It seems hard to look in God's cards. But I cannot for a moment believe that He plays dice and makes use of 'telepathic' means (as the current quantum theory alleges He does).
  • What nature demands from us is not a quantum theory or a wave theory; rather, nature demands from us a synthesis of these two views which thus far has exceeded the mental powers of physicists.
  • However I cannot seriously believe in it because the theory is incompatible with the principle that physics is to represent reality in space and time, without spookish long-distance effects.
  • Useful as it is under everyday circumstances to say that the world exists “out there” independent of us, that view can no longer be upheld.
