Default Re: Science Saturday: Problems in Quantum Mechanics

Nice overview, guys. Liked the stuff on the GRW theory, and will look at it more. Maybe in the future you can delve some more into Bhomian/hidden variables interpretations. Just a quick note: there seem to be some interesting cases of determinism breaking down in classical mechanics. A bunch of these are discussed at
http://plato.stanford.edu/entries/de...causal/#ClaMec
I'll just quickly quote/mention 2 of them:
"Consider three identical point-particles approaching each other at 120 degree angles and colliding simultaneously. That they bounce back along their approach trajectories is possible; but it is equally possible for them to bounce in other directions (again with 120 degree angles between their paths), so long as momentum conservation is respected."
The other example I'll note is that of a frictionless dome at the apex of which a point particle is placed, and which spontaneously falls to one side while not violating Newton's laws...
