4.0 von 5 Sternen A Very Good Book With Flaws
I have taught from Griffiths' Introduction to Electrodynamics twice now. It is a very good book. The selection of topics is good, and the mathematics is clear. The prose is enjoyable.

3.0 von 5 Sternen mediocre, but better than his quantum mechanics text
We used this text for a junior level year long E&M course at UC Berkeley. Griffiths electrodynamics text, as well as his quantum mechanics text, both suffer from the same problem of being too elementary. Classical electrodynamics is supposed to be the place where undergraduates start to really see some more complex mathematics. However, the only special function...

4.0 von 5 Sternen A Very Good Book With Flaws, 23. Dezember 1999
I have taught from Griffiths' Introduction to Electrodynamics twice now. It is a very good book. The selection of topics is good, and the mathematics is clear. The prose is enjoyable. A few problems follow each section. These problems need the material just covered. The end of the chapter problems can be very challenging. This distribution of problems is very helpful. There are useful references to American Journal of Physics. Time with Griffiths is very well spent.
Here are a few flaws. The first half of the book is much more complete. Perhaps, Griffiths became weary after chapter 7. There are indications. Figures and references are fewer. Surprisingly, the third edition did not correct this imbalance. It is essentially the second edition with some renumbering of sections and problems (making the second edition less valuable as a used book). An even bigger surprise is that in the third edition some examples became problems!
The text is often too brief. If you want the full text of subtle arguments, go to Purcell. Compare, for example, the two discussions of the average field, or the two discussions on multipole expansions.
A more striking difference between Purcell and Griffiths is the special relativity connection. In Purcell it is the heart of the discussion of magnetism. With just the transformation of forces between frames, magnetism appears. In Griffiths it is the last chapter. Griffiths is very formal with superscripts and subscripts unleased in full force.
The book (like Jackson) is often a vehicle to teach mathematical physics. There is very little real life electricity and magnetism in Griffiths, e.g. no bubble jet printers in electrostatics, no magnetic tape in magnetism. We need to look elsewhere for practical matters.

We used this text for a junior level year long E&M course at UC Berkeley. Griffiths electrodynamics text, as well as his quantum mechanics text, both suffer from the same problem of being too elementary. Classical electrodynamics is supposed to be the place where undergraduates start to really see some more complex mathematics. However, the only special function which is used in Griffiths is the Legendre ploynomial. No mention is given to Bessel/Neumann functions and their spherical cousins, Green functions, Fourier transforms, or spherical harmonics. Strangely enough, he uses Green functions in his quantum mechanics text in a place where they aren't even really necessary (the scattering section). When mentioned in the QM text, they aren't even really Green functions, but rather propagators which are distinctly different objects. On top of the rather low mathematical level of the book, there are many topics left out of the last sections on EM waves and radiation. No mention is given to diffraction or interference. Classical scattering of EM waves isn't covered (even though scattering is covered in the QM text in a confusing manner). For some strange reason, he decides to put the Lienard-Wiechert stuff before simple dipole radiation which is ridiculous because point charge radiation is a far more difficult subject than multipole radiation. Quadropole moments (in static potentials and radiation) are only covered superficially in the problems. Incidently, his multipole expansion of radiation only goes to the electric dipole term; the most boring term.
On the good side, although using Green functions for the retarded potentials is more convincing, Griffiths geometric argument is nice. The parallel between the chapters on magnetic and electric fields in matter is very nice. The notation is very clean throughout the text (except for the strange u vector in the Lienard-Wiechert fields). All in all the first seven chapters are good and pretty solid. The last five chapters are pathetic.
In the end, Griffiths text is nice, but it should really be augmented with the Heald and Marion text or (for the brave) the newer Schwinger text (very nice, mathematically rich). Undergraduate preparation with only Griffiths would leave one rather unprepared for Jackson as a graduate student.

5.0 von 5 Sternen Great Book for Junior/Senior Undergrad Course, 22. Februar 2000
Von 
Reviewer (Near Columbus, OH United States) - Alle meine Rezensionen ansehen
I find the author's writing style to be wonderfully entertaining, which is something that is rare in a physics textbook. His examples are useful and his derivations are precise. The book is not overly elementary by any means, as some critics of Griffiths will claim. There is a section in the book using separation of variables and Legendre Polynomials to calculate the electrostatic potential for various configurations, and this section is sufficiently challenging. However, Griffiths does not confuse the student with extravagant narrative nor does he intimidate his readers by introducing a proof and "leaving the rest as an exercise" with little guide as to how it should be done. I have decided that Griffiths is one of the best authors that I have encountered in my undergraduate career, and finding a good author is rare.

5.0 von 5 Sternen This may be the best textbook on any subject ever written., 17. März 1999
Von 
This textbook may well be the best textbook on any subject ever written by anybody. When I took my course at Grinnell College using this book, it was as though there were no need for lecture. The professor even admitted that with a text this good, the subject pretty much teaches itself. I cannot recommend a book more highly than I recommend this book. This language used to convey the information is so well-motivated that the student does not have to work on understanding what is going on.

5.0 von 5 Sternen Do they give noble prizes for literature in physics?, 24. Juli 1999
Von Ein Kunde
If so, Griffiths has got my vote. This text is everything a physics text book should be. Griffiths presents material in a clear fashion like the brilliant teacher he is. And always there is a touch of genuine humor but reverence for the material. There are plenty of examples as well. The only down point is that the problems are too easy, but I guess that's O.K. You don't learn physics by struggling and failing to solve ridiculusly complicated problems.

5.0 von 5 Sternen This is an amazing book, even for non-physicists!, 4. Oktober 1999
Von Ein Kunde
Introduction to Electrodynamics is the most eloquent text I have ever read. Griffiths has an unbelievable knack for explaining the confusing nuances of the math behind the science. As a mechanical engineer I use this book extensively in the study of Fluid Mechanics, as it has the best explanation of Vector Calculus I've seen. Society will be blessed if Dr. Griffiths continues to write.

3.0 von 5 Sternen Well written, but not a good standalone., 5. Dezember 1999
Von Ein Kunde
I used this book as a reference in a yearlong E&M sequence. Although I agree that the book is well written, I also think it has several flaws. First, the topics are presented in a desultory fashion (Special techniques in Chapter 3?). As many others have said, the book needs an answer key. Griffiths mentions that many people advised him against odd numbered solutions - tell them not to read the answers!
I found 'EM Fields' by Wangsness to be much better as a text. I don't think Griffiths has enough math (or detail about electrostatics) in it. Granted, the book is meant as an introduction, but many people think they can read Griffiths and then go right into Jackson. I think many of the people who subsequently whine about Jackson simply haven't had enough of the basics.

2.0 von 5 Sternen More information necessary to make this a better book!, 16. Januar 1999
I am enrolled in the upper division sequence of Electromagnetism as a physics major. I, along with most others in my class agree that the book needs more examples, and at least the odd numbered problems need to be printed in the back of the book. We need to study more examples to learn technique. When we attempt to solve the problem sets, we have no idea whether or not we're getting the right answers. The layout of the book is okay, and the text is written in a "matter of fact" informal style which I find unique and uncommon in textbooks of this type- but I feel I need to buy another textbook to make up for the other shortcomings.

5.0 von 5 Sternen Good presentation of the subject !, 26. Mai 1999
Von Ein Kunde
The best thing about this book is that it's contents are in right sequence ! Quite often the subject matter is jumbled but here the author has started with Calculus giving ample background about the tools we use for QED /ED etc. and has proceeded in similar fashion throughout the book. The prose is explained with rare lucidity but still the level of problems is not that tough as I expected !

5.0 von 5 Sternen Exceptional review of introductary E&M, 3. November 1999
This book is by far in a class of it's own. I had the pleasure of going throught the entire book and loved every page of it. It is clear that Griffiths loves teaching, and his wit and humor throughout the book keeps a light atmosphere. One flaw: not nearly enough on transmition lines and the relativity section could use some work.
