I used S in the 80s, it was a Bell Labs language, just like A, B, and finally C. So didn't they get the name wrong? Shouldn't it be T or maybe even U by now?

I don't know who to blame - Broadcomm, Dell, or Microsoft, but Broadcomm chipsets (a.k.a. Dell 139x series) still can't do WPA2-Enterprise in Windows Vista. Intel? No problem.

I think I used Arfken for a two semester grad course. My Ph.D. is in geophysics, but this was a terrific book for any scientist expecting to utilize physics in their work. I don't think Feynman is appropriate. I can't believe that a Ph.D. student in math (a) has never taken a physics course, and (b) has not taken PDE and is already in 3rd year of program. In all Ph.D. programs that I'm familiar with, by 3rd year you're only taking courses that directly pertain to your specialty.
