Wow that was very impressive. I am off to find one of demos you mentioned above.

Comment on Do We Really Understand Quantum Mechanics ? by Knut Holt

Knut Holt — Sat, 21 Jun 2008 19:58:57 +0000

I do not think quantum mechanics give any deeper knowlwdge at all. It is solely a procedure for predicting the possibiity of observational results, nothing else.

Therefore it is nothing to understand beyond this. To get an understanding, something entirely new must be developed.

AT FINITE TEMPERATURE THERE WILL BE FLUCTUATIONS WHICH WILL DRIVE THE SYSTEM TO A LOW ENERGY STATE IN COMPETITION WITH THE INTERACTION.

You’re indeed right. Have corrected the mistake now.

Sorry to be pedantic, but isn’t that the negative of the traceless part of the tensor of inertia?

Comment on Does Position operator generate momentum by nayagam

nayagam — Sun, 10 Feb 2008 17:20:09 +0000

Hi gojib,
The momentum operator does not become ambiguous when the position operator is diagonal !

What happens is that when the position operator is diagonal, the momentum operator becomes non-diagonal which in turn leads to an uncertainty in momentum.
