Us Nuclear Weapons the Secret History
YA Nuclear weaponry in the U.S. has been a top secret subject since its invention in the 1920s. Hansen here presents an encyclopedic discussion of all of the various nuclear explosives developed, tested, and used by the U. S. Department of Defense. Much of the material was declassified for this book, and Hansen emphasizes his opinion that the secrecy was and is unwarranted. He provides technical details of the physics concepts, as well as political and tactical justification for development of various individual warheads. Students maturing in a nuclear age may wish to be well informed about the sources of their possible destruction; they may also be curious about the scientific principles used to design the weapons. The thorough index and footnotes, as well as appropriate photos, charts, and diagrams make this title a useful one in schools with strong physics curricula .Jim Boyd, Episcopal High School, BellaireCopyright 1988 Reed Business Information, Inc.
