I think Feynman said that all of quantum mechanics is contained in the 
double-slit experiment.  The following page seems to explain it in good 
detail, though I suspect the electron experiment is a simulated 
experiment of the sort Feynman would not have approved.  Also it does 
not discuss the issue of local variable theories:

leSlit.html

The following page goes into the key issues a bit more:

http://www.thekeyboard.org.uk/Quantum%20mechanics.htm

Those are two of the first pages I found in Google - I don't know 
whether they are the best pages or not, but at a glance they don't seem 
too bad and they go into a lot of detail.  You may find more.  

But anyway, understand the double-slit experiment, or at least know 
what happens, and you'll know something about QM.
