Classical field theory reviewed by a master., Dec 19 2001
By A Customer
This review is from: Classical Field Theory: Electromagnetism and Gravitation (Hardcover)
Francis Low is an outstanding theoretical physicist who also happens to have an interest in education. He wrote marvellous lectures on quantum scattering, where the misteries of the so-called Sommerfeld radiation condition were clarified (and derived!) by using wave-packets. His name in science was made mainly by the epoch-making paper, with Gell-Mann, which introduced the now ubiquitous renormalization group. It is noble of him to dedicate some of his time to write his vision of electrodynamics and gravitation, as examples of classical field theory. This is an advanced book, meant to deepen and unify concepts. But Francis Low would'nt stop at that. You'll find fresh views almost at every page, mainly on the electrodynamics part, his turf. Some criticism has been made, by Robert Wald, for instance, about his treatment of gravitation, which is more or less alla Feynman, or alla Schwinger: geometry is discovered. It is not the starting point, like in Einstein. This is also welcome: it puts your mind to work along different tracks. All in all, a great reading.

Too Abstract and Too Abstruse, Mar 6 2009
By Ronald W. Satz - Published on Amazon.com
This review is from: Classical Field Theory: Electromagnetism and Gravitation (Hardcover)
I enjoy collecting and reading field theory books. Prof. Low's book is very handsome on the outside, and the chapters appear to be enticing on first sight: Electrostatics, Steady Currents and Magnetostatics, Time-Dependent Fields and Currents, Radiation by Prescribed Sources, Scattering, Invariance and Special Relativity, Lagrangian Field Theory, and Gravity. But, with the exception of very, very gifted physics Ph.D. students and authors who've written on this subject, almost everyone will find the book way too difficult to comprehend. Most of the integrals do not specify limits or coordinate systems, and most of the tensor equations don't specify the indices--Prof. Low assumes that the reader can simply figure them out! There are no solved problems, no applications, and the exercises are--for the most part--mini-research projects! Prof. Low says in the Preface that his book is a textbook rather than a treatise, but it sure reads like a treatise. Most students and graduates would be better off studying the Schaum's Outline 2000 Solved Problems in Electromagnetics.

If you already own Jackson, Griffiths, and Barut, don't bother, Jun 1 2006
By twan - Published on Amazon.com
This review is from: Classical Field Theory: Electromagnetism and Gravitation (Hardcover)
Difficult to understand, very few examples, and the problems aren't very good at telling you what they are asking for. Maybe good if you already have a decent understanding of E&M, but this is not an appropriate text for a first graduate level class. Use Jackson for most stuff, fill in the gaps of what you missed as an undergraduate with Griffiths, and use Barut for the field theory stuff.
