Yes it does.
Heisenberg Uncertainty Principle. Ring a Bell?
The uncertainty principle says that there is a limit on the information about position and change in position that you can collect. It does not rule out internal states. For instance, you could generate particles with a certain property which you do not have to measure to know that they have that property.
It is a logical mistake to think that because you can't see it in 2002, you can't ever measure it, or it doesn't exist. When something appears 'random', it is because of (wholly normal) ignorance on our part. Sometimes 'randomness' is used to shut off analytic machinery, much like 'God' (this latter idea is Minsky's).
Oh dear. QM does rule out internal states. I didn't think I would have to explain why I capitalised "Bell", but perhaps it was a bit too subtle. Google "Bell" and "inequalities", and go from there. The uncertainty principle was generally considered to rule out internal states long before Bell, though. Since around 1930, I think. Whether QM/the uncertainty principle is wrong is a different question. -- Peter Fairbrother ps Are you a PFY (or a PFO), or is your name really Variola?
