The best explanation of entropy and thermodynamics I've ever seen
I'll give a second on that, very well done.
Parenthetically to Rrhain: Sears/Zemansky? Didn't the ancient Romans use that text book?
It would seem so. That rang a bell so went to the bookcase and pulled my 1st year Physics text. It is Modern College Physics by Richards, Sears,Wehr, and Zemansky second printing March 1964 (copywrite 1962). God, I'm getting old! The price I paid for it is stamped on the inside cover, can you believe........$15.95.
