In this book the author looks at the continuing debate about the meaning of quantum theory. The historical development of the theory is traced from the turn of the century through to the 1930's, and the famous debate between Niels Bohr and Albert Einstein. The book examines in detail the arguments that quantum theory is incomplete, as made by Einstein, Boris Podolsky, and Nathan Rosen; the development of Bell's theorem; and crucial experimental tests performed in
the early 1980's. Alternative interpretations - pilot waves, quantum gravity, consciousness, many worlds, and God - are described in the closing chapter. This book is aimed at
graduate and senior undergraduate students of physics and chemistry taking quantum chemistry or quantum theory courses, and other scientists interested in the subject.
`I can recommend it warmly. Baggott has a practised, informal, attractive style taht renders the potentially turgid digestible . . . , he gives a lucid, thoughtful, and helpful account of one of this century's great conundrums.' The Times Higher Education Supplement
'Baggott is a chemist; he combines scepticism with an honest and painstaking effort to understand the message coming from the Copenhagen priesthood, the physicists Irwin Schrödinger, Niels Bohr and their colleagues. He tries, with refreshing modesty, to pass on the results of his labours ... Baggott has an entertaining style, with clever use of analogies and diagrams - and, above all, its realist honesty that shines like a beacon through the fog of
contemporary mystical specualtions.'
Trevor Marshall and Max Wallis, New Scientist
'The book is clearly written and should be of interest to all scientists and mathematicians.'

'this reasonably priced and well produced book forms a valuable bridge from basic undergraduate knowledge to the real stuff'

'Baggott's strength lies precisely in his appreciation of the problem of making real measurements on microscopic quantum systems using macroscopic devices. Baggott has an entertaining style, with clever use of analogies and diagrams - and, above all, its realist honesty that shines like a beacon through the fog of contemporary mystical speculations. The final sentence is particularly worth noting: "If you find the theory difficult to understand, this is the
theory's fault - not yours."'
