The Electromagnetic Universe 6th Edition

This book is a fairly comprehensive treatise on electromagnetism and gravitation. These two topics are not usually discussed together, but I have found that there is some relation between them.

This is a mathematical treatment, so might be difficult for some. If the reader has had an undergraduate class in electromagnetism (300 level in the American system), the book will be an easy read, even more so, because the derivations are explained in detail. If the reader has had some physics that includes electromagnetism (1st year college or advanced placement in high school), this book could be accessible with a little supplemental reading in vector analysis and differential equations.

The mathematics is not the focus of the book. Each derivation is designed to reveal some physical principle and the math employed is the simplest possible to make the point. The derivations have been selected in such a way as to incrementally expand the scope of electromagnetism starting from a very limited set of postulates.

In this 6th edition there are some critical changes. The biggest change is that the scalar field is not included. I am now convinced that it does not exist. So the book is a little shorter. However, I have also worked out some additional derivations with interesting results.
