BooknewsProvides researchers with a logically organized, notationally unified and usefully detailed account of essentially all that is presently known (much of it quite recently learned) about the Klein-Gordon and Dirac equations and their classical counterparts - equations which describe the motion of charged particles in the presence of various externally impressed electromagnetic field configurations. Two long appendices treat some related non-relativistic topics. Expensive, but an invaluable treasure. (NW) Annotation c. Book News, Inc., Portland, OR (booknews.com)
