The Science of Radio by Paul J. Nahin (AIP Press, distributed by Oxford
University Press, £10, ISBN 1 56396 347 7) takes a top-down look at the
superheterodyne AM radio receiver as a sociological and technological
development. It describes the advances that made radio possible and links these
with mathematical and physical theory. Students and teachers should find this
novel approach to radio theory stimulating and helpful.
