This topic is driving me crazy. I have read every thread dealing with the OPs question and have not found a satisfactory answer. bcrowell had an interesting point, but needs further expansion. John goes off on a rocket while Jill stays on earth. When John returns, he has aged less due the...

..anyone who used this book to study for the Physics GRE test willing to sell it? I can't find used copies anywhere.

In thinking of the Stern Gerlach experiment, I understand how the magnets can be aligned along the z-axis, and along the y-axis (assuming y-axis is perpendicular to propagation)..but how do you orient the magnets in the x-direction (along the propagation) to measure spin x? Wouldn't that block...

Beck's book is the one to get. He starts with polarization (with detailed experiments that can be done in the lab) as a gentle 2D vector introduction to QM. Most other texts start with spin (which is abstract unless you're familiar with Stern-Gerlach experiment), bore you with the formalism...

Thanks for the feeback! My main purpose is to experiment with entangled photons using a B-BBO crystal.

I'm looking for a good laser for optic experiments. All the professional papers I've read show the use of a 351nm Argon Ion laser. A new 30 mW one of these is about $6,000, but I see used ones pop up on Ebay from time to to time. My question is, is there a difference between this laser used...

DrChinese, thanks, that's exactly what I was looking for !

Does anyone know the full specs for those pump argon lasers used in the quantum eraser experiments? We're can I buy a used one? Also, is there a good place to buy the other equipment (lenses, crystals, etc) needed to perform the experiment? thanks! Lux
