Quantum Physics United with non quantum Physics

[evanallmighty]

Could it be that there is no way to unite quantum physics and (non quantum) physics, could that be why there has been so many problems and controversy over string theory?

This would just help me understand string theory more and possibly help out my "pet theory"

Er.. what makes you think there's no way to "unite" them? Have you ever even studied QM formally? Look at the quantum SHO, and solve it for very high quantum number "n". Doesn't that begin to approach the classical limit as far as where the particle is predicted to be?

Furthermore, it appears as if you've never heard of decoherence before, or visited our "Recent Noteworthy Paper", where several papers have been highlighted that showed how classical scenarios can be obtained out of quantum mechanical starting points.

"Pet theory" is awfully full of holes when one is ignorant of the subject matter.

Zz.

Then you are left with a murky problem as you start getting down to small sizes of when you need to use quantum mechanics. There is a whole pile of things in nanotechnology that require both calculations at different points.

This means both theories are wrong or they break down at this level there is no specific size we switch from one to the other.

In 2007 scientists entangled atoms 1m apart.
Last record I saw had 14 calcium atoms this year
We have recorded quantum effects in a molecule of 400 atoms April this year that's about the size of an insulin molecule (http://www.sciencedaily.com/releases/2011/04/110405151213.htm)

Thats all starting to get quite large ... so what's your random cutoff distance and why?

thanks ZapperZ and Uglybb, I am just wondering more on string theory, as I have not really studied it closely.
