This book was assigned in a class I took on the computer modeling of materials. The text itself was slightly above my understanding; but thats fine, I just was not prepared for it. The problem is that there are many exercises that require the reader to download software from the author's web site, and use it to perform calculations. Many times the software did not work as intended, and so the professor had to spend time correcting the code, or writing his own version. And of course there were the usual problems of installing the code properly, compiling it, and executing it. This idea would have worked much better if the necessary code was put onto a CD-ROM that came packaged with the book. For the software problems I dock one star out of five.

The introduction states that this text is intended for graduate students in physics, chemistry, materials science, or electrical engineering, and who have taken classes in numerical analysis. I think a more appropriate wording is that this text is for someone versed in all of these listed fields. There is extensive use of thermodynamics, symmetry and crystal structure, linear algebra, statistical mechanics, quantum mechanics, etc... This book should not be used as an introductory guide to computational physics or related fields. The necessary prerequisite knowledge is quite extensive.

The intro should specify at least 2 college classes in computer programming as a prerequisite for this book. The programming assignments included at the end of each chapter are quite challenging, and should not be attempted by someone without previous experience in writing mathematical codes. This here lies another problem with the approach taken by this book. Most science and engineering majors will take 1-2 courses in programming as part of their university education, but these classes often emphasize business applications such as reading / writing to a text file, creating and using databases, formatting of screen output, linked lists, etc... These skills are not very useful in writing a code to do computations. For the latter, needed skills include parsing data, recognizing patterns, using built-in functions, importing and using algorithms from online libraries. utilizing large matrices and vectors, etc...

What the author should have done for each computational homework problem is to write out the solution (code) himself, add in the documentation, and then removed the code while leaving the documentation intact. The student can then use the documentation to craft his/her own solution.

For the difficulty of the computing problems, and of the text in general, I dock another star.

Therefore, I rate this book 3 out of 5 stars.

This book by J. M. Thijssen is a rare gem. You note this as you browse the index. Quantum scattering, variational methods for the Schrödinger equation, the Hartree-Fock method, density functional theory, classical and quantum molecular dynamics and Monte Carlo methods and transfer matrix methods. Even a solid chapter on lattice field theory! The book isn't child's play (like most books on computational physics), but a beautifully written text covering both physical and computational issues, superficially but concisely. A neat selection of references guides readers to comprehensive, modern literature. The right balance of tricks and theory puts the readers few steps away from developing their own code. I don't award the fifth star because software engineering and object orientation issues are ignored.

This is a very decent book on computational physics, focusing primarily on condensed matter. It's up there with Allen and Tildesley's "Computer Simulation of Liquids", though with a broader selection of subjects and more suited to physicists.

There are inevitable errors, some of which would take a bit of effort to fix were it not for the error web page the author maintains.

Many problems in condensed matter are tackled, always with a view toward implementing an actual numerical investigation (this may sound like a given, but several other texts seem to shy away from actually using a computer, exploiting some variant of 'computational' in the title as an excuse to write yet another redundant physics text that is only cursorily computational). Often, nice snippets of pseudocode are presented, along with suggestions for numerical control parameters to use and the corresponding numerical results obtained - so one can try things out and check the answer. Indeed, the book is best used if one sets about to write code to solve problems, both in the main text and in the exercises at the chapter ends. As is often the case, however, getting a piece of new code to behave correctly can be a bit of a pain, which becomes easier only with experience.

In a real sense, the text helps bring some physics to life, and one is rewarded, I think, with a clearer understanding, and some powerful tools at one's disposal.

Though it doesn't have any real competitor, there is room for a second edition: along with correcting errors, several subjects could do with a bit more discussion or even extensive treatment, and other things could profitably be included, e.g., a DFT implementation of Car-Parrinello quantum atomic dynamics.

This is a really good book for people starting out on computational modelling like me. I am currently doing a graduate degree in Materials Science and Engineering and this book has proven to be enormously useful.

Ok, ok, my title seems a little aggressive, but trust me, if you are looking for a *computational physics* (C.P.) book, this is not a good choice. I have been lecturing an introductory computational physics course for two years, and, by far, the most adequate books I found (and use) were Giordano & Nakanishi and Landau & Páez ones. Dr. Thijssen's book is highly concentrated on condensed matter physics, and it has *too few* graphics, figures, or illustrations. In my sincere opinion, is by far the worst book on C.P. I have bought, and I do not recommend it, at least for those who want to learn C.P. "from scratch". Ok, ok, it can be considered a "high level" book (maybe adequate for graduate courses), but I think that it lacks the main points on "pure" C.P. The reason for the two stars is because I am a condensed matter physicist, and therefore the book will at least serve as an additional reference on this subject.

I read several computational physics books before but never finished the second chapter. Most books on this subject expect the reader to become an expert after reading them, which is impossible! The authors themselves spent years to achieve their levels so they should have a practical expectation for the readers, especially undergraduates.

I am not saying Thijssen's book is easy. It's far from the truth. I am only saying that Thijssen knows about the reader's difficulty when reading this book and doing its exercises! He not only explains the physics problem but also illustrates the technique to do the computation.

Even though, this book is not for beginners, it's ideal for graduate students on experimental physics (students on theoretical physics need to know beyond this book). Also, it will save the read tons of time if he use Mathematica instead of C or Fortran for programming.

I found this book as thorough as I can think of without losing
the depth.
Probably, this book is not intended for anyone without a
solid physics background. You need to have a solid senior level
or beginning graduate school level physics to fully
appreciate the content. If you are not that prepared, then
read first "An Introduction to Computer Simulation Methods"
by H. Gould and J. Tabochnik.

I think that the price of the book is very reasonable now.
It used to be 50$+ just a year ago. Cetainly, by NOT
including the CD they could keep low the cost of
production.
