They seem to think the world is two dimensional*. A reference I just
found this morning may be more to the point: "Fields and Electrodynamics:
A Computer-Compatible Introduction" by Pieter B. Visscher. Chapter 16 is
devoted to this and more. I got this book from a publisher's rep some
time ago. I hadn't really looked at it much before this morning. The book
may be obscure; Amazon shows it as out of print. It was published in 1988
so check you unperused publishers' samples.
