It's not QUITE that bad..., 12. Dezember 1999
Yes, it is very mathematically demanding. Yes, some of the discussions (particularly towards the ends of chapters) are thoroughly inpenetrable. And yes, each chapter features a few problems of the type "Show that (horrendous expression)=(even worse expression)=(multiline, triple sum of modified Bessel functions expression)." But with a serious effort you'll make it through the first 3/4 of every chapter and >half the problems; the remaining parts are usually specialized topics anyway. The hardest part of studying this text is simply the large amount of time you need to invest; it doesn't read like Griffiths' book. And what did you expect, E&M to be easy? To those of you who truly hate this book (and judging by the reviews, there's a fair number of you), you might try the following substitutes/supplements: 1) Landau's Classical Theory of Fields: covers E&M in vacuo, with special relativity present from the beginning. Worked problems, E&M section is ~200 pages. 2) Mathews and Walker, Mathematical Methods useful for special functions (Jackson's Chap. 3 presentation is somewhat brief). 3) Landau's Electrodynamics of Continuous Media covers E&M in matter. I haven't used this one (yet), but people seem to love it. Again, worked problems. (Of course, find them in the library first!)

Useful only for its continuum mechanics coverage, 3. Dezember 1999
The first half of this text covers the standard graduate mechanics cirriculum, while the second half covers strings, membranes, and other continuum topics. The section on particle mechanics is poorly done: the entire section on Hamilton's method is bad, and the treatment of the HamiltonJacobi method is disastrous (of all the topics to mess up!). The discussions offer no insight into the material being presented; both the small oscillations chapter and the Hamilton mechanics chapter are simply collections of formulae. I also disagree with their approach to Lagrangian dynamics. They, like Goldstein, begin with a tedious discussion of virtual work and D'Alembert's principle. I prefer Landau's approach just introduce the action and get on with it. I don't believe that anything is learned from their method. Much of the book reads as if the authors are just piecing together the relevant sections from other texts, while removing the copied authors' insights. Indeed, they're caught redhanded in chapter 1. Not only are problems 1.17, 1.18 directly from Landau's text, the wording is identical, the problems are divided into the same parts, and just as problem 1.18 directly follows 1.17 in this text, it directly follows the same problem in Landau's book. This book really doesn't do anything in partcle mechanics well. It's examples are trivial (a common problem), and modern methods (see V.I. Arnold's book and a dynamical systems text) are omitted. There's no reason to use this for particle mechanics when Landau's beautiful text is available. And although I've never used it, I'd wager that Landau's continuum mechanics book is better than this text's coverage...

You'll love stat mech after reading this text, 26. November 1999
My first exposure to stat mech was through Callen's book "Thermodynamics and Thermostatistics" in my junior year of college. I hated the book, and decided right then that I never ever wanted to become involved with condensed matter physics. However, I needed to know stat mech for my grad school qualifying exams, and not wanting to go back to Callen, I picked up Reif's book, following a professor's recommendation. What a difference. The clarity of presentation in this book is matched only by Landau's texts. You'll be amazed when doing the problems by just how much interesting physics you can do with just the fundamental relation of thermodynamics and the canonical formalism. Don't be turned off by the length of this book (>600 pages); the reason for this is not overly wordy descriptions (i.e, Griffiths), but simply huge amount of material presented (Griffiths would take over 1000 pages to chat about the same amount of material). Perhaps the best praise I can give this book is that not only did it teach me stat mech, it really sparked my interest in the field of condensed matter physics, enough to contemplate my choosing this as a research topic in grad school.

Do not listen to the negative reviews!, 13. November 1999
This book and its sequel are, quite simply, the best fantasy novels published in the past 20 years. In fact, the only other fantasy stories I enjoy as much as these two are Leiber's Fafhrd and the Grey Mouser tales (these books are better than Jordan's!). The character development is superb  Arya Stark and Tyrion are two of my favorite characters in fiction. Even the minor characters (Bronn, for example) are better developed than characters in many fantasy novels. If you read the reviews on this site for this book and its sequel (A Clash of Kings), you'll find a few people with two major criticisms of these books: 1) too much sex and swearing and 2) negative portrayals of women. Ignore them. They're wrong. This is a realistic novel; this stuff happens in real life. At no point in these books are such incidents graphically described; the reader always hears of them after their occurrence. In fact, I would say Martin is far better at portraying realistic female characters than his contemporaries. He's certainly better at it than Jordan, who's females are all annoying shrews. Arya Stark, for example, is arguably the best character in the book. Don't let the puritans and feminists prevent you from reading a great book! And to those of you who've read the books: my bet's for Lyanna Stark and Rhaegar Targaryen ( it seems so obvious, even before hearing the rumors).

My favorite physics text, 9. November 1999
I truly love this book. The sections that Sakurai wrote could not have been written better. He uses Dirac's notation from the beginning, which provides the reader with a much better understanding of what's going on than the usual wave mechanics intro. There are some weak points, however mostly sections that were added after Sakurai died. The treatment of timeindependent PT in chapter 5 is unnecessarily wordy and complicated. Chapter 6 on multiparticle states is fair to brief. I didn't think that the scattering sections in chapter 7 were very good, but I haven't seen it done well anywhere else either. Everything else, however, is wonderful.

Relaxed introduction to abstract algebra, 9. November 1999
An easy, relaxed introduction to groups and rings. There are lots of problems (most fairly easy, but some were difficult) to hone your skills. The biographical info at the end of each chapter made the book fun to read. It's not, however, a very rigorous book, and I personally didn't like all the info about cryptography. I completely disagree with the previous reviewer on one point it's no good for a mathematical physics class. I don't think it even talks about continuous groups or Lie algebras, and if it does, it talks about them very briefly.
