A collection of over 50 recent color photographs are also included allowing the reader to survey the surviving elements of these mighty defenses. A product of extensive research, this book brings together for the first time rare images and the little known history of the Delaware Bay

Written by a renowned professor of physics, this introductory text is geared toward graduate students taking a year-long course in quantum mechanics in which the third quarter is devoted to relativistic wave equations and field theory. Difficult concepts are introduced gradually, and the theory is applied to physically interesting problems. After an introductory chapter on the formation of quantum mechanics, the treatment advances to examinations of the quantum theory of the free electromagnetic field, the interaction of radiation and matter, second quantization, the interaction of quantized fields, and quantum electrodynamics. Additional topics include the theory of beta decay, particles that interact among themselves, quasi particles in plasmas and metals, and the problem of infinities in quantum electrodynamics. The Appendix contains selected answers to problems that appear throughout the text.

Bermuda has been fortified since it was first occupied by the British in the 17th century, with some 50 forts constructed up to 1945. This new study describes these fortifications in detail and will appeal to the many visitors that come to the islands each year, as well as those interested in Caribbean fortresses.
