Comment : This is an article which appeared on AJP quite sometime ago. I think it does a good job of talking about various weird things which crop up in quantum theory. It’s quite loooong, but I guess depending on what your background and interests are, you can safely skip a lot of it.
So, tell me what do you think of this article. You can post any interesting link related to this subject in the comments below. By the way, for those who are not familiar to blogs, you can click the link below with “comments” written on it and leave your comments there.
And well, if you worry so much about your privacy that you don’t want to leave your name here (Horrors !) , then comment with name as anonymous , but do leave a valid e-mail(Say the iitk email) so that we among ourselves can figure out who is commenting. The email ID will not appear here – to see the email ids of the commenters one has to login using username+Passwd. We will soon try to come up with an About page How to post in this blog page with all such info.
And again, Comments please !

Also have a look at an article by Roland Omnes – Consistent Interpretations of Quantum Mechanics.

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.
