Lecture notes on "Elasticity" and "Statistical Mechanics"
Submitted by Cai Wei on Fri, 2008-06-06 01:50.The lecture notes of the two courses I taught at Stanford University during the last two quarters, "ME 340 Elasticity" and "ME 334 Introduction to Statistical Mechanics", are available in PDF format online at:
http://micro.stanford.edu/~caiwei/me340/
http://micro.stanford.edu/~caiwei/me334/
Perhaps it could be useful to you.

What is "randomness"?
Submitted by Ajit R. Jadhav on Sat, 2007-04-07 05:43.Does the word "randomness" have antonym? If yes, what is it? Why? What view of randomness does that imply?
The notion of randomness is, of course, basic to both statistical mechanics (or kinetic theory) and quantum mechanics. But these are not the only fields where it is relevant. The notion also appears virtually in any field where probabilities are used. For example, we speak of random loads and vibrations (in structures and machine design), random noise (say, in acoustics), etc. But what does the term "randomness" really mean? Any idea? What would you say? Here, I am here looking for brain storming, so half-baked ideas, side comments, etc. etc. are welcome.

A Fresh Look at a Beautiful Subject
Submitted by Zhigang Suo on Mon, 2006-09-18 19:37.This is a review on Thermal Physics by Charles Kittle and Herbert Kroemer. I posted the review on Amazon on 2 December 2001.
This is by far THE BEST textbook on the subject. As many people say, thermodynamics is a subject that one has to learn at least three times. I can easily understand the very negative review from the undergraduate student at Berkely. The subject itself is hard, and simply is not for everyone, not for the first run at least. I say this from experience. I earned a Ph.D. degree over ten years ago, and took courses on thermodynamics at both undergraduate and graduate levels. I didn't understand the subject at all, and didn't find much use in my thesis work. However, something about the subject has kept me going back to it ever since. I now own about 40 books on the subject, and use the ideas almost daily in my research.
