*The Quantum Universe*. 1987, with Patrick Walters1996, with Richard P. Feynman, Robin W. Allen*Feynman Lectures on Computation*.*Feynman and Computation*. 2002

For so long the province of mathematicians and physicists alone, the beauty and significance of quantum mechanics has remained hidden to the nonspecialist. Yet its impact on technology has been enormous. The modern electronics industry with the silicon chip that has revolutionised so many aspects of modern life owes its existence to an understanding of the quantum nature of semiconductors. Likewise, the myriad of applications of lasers arise from an observation by Albert Einstein on the interaction of light quanta with atoms. Phenomena as wide-ranging as superconductivity and neutron stars can be explained by the same basic principles of quantum mechanics.

The challenging ideas of the originators of quantum mechanics, Prince Louis de Broglie, Erwin Schrödinger and Werner Heisenberg, were originally used to solve the problems of atomic physics, but have proved equally successful in predicting the properties of the tiny nucleus at the heart of the atom. Quantum mechanics has given us great insight into the nature of the universe, promising an unlimited supply of energy from nuclear power and unlocking the awesome capability for self-destruction through nuclear weapons.

The text explains exactly what quantum mechanics is in a simple non-mathematical way,
and is complemented throughout by many superb colour and black-and-white photographs
illustrating the varied facets of quantum phenomena.
There is a liberal supply of amusing and interesting anecdotes
about the physicists who have contributed so much to our present understanding of quantum mechanics.
*The Quantum Universe* will provide a fascinating and accessible introduction
to one of the most important scientific disciplines of the twentieth century.
Final-year students at school, general readers with an interest in science,
and undergraduates in science subjects will all be able to enjoy and benefit from this novel exposition.

Most people who write books about computation starting at the level
of assembly language would then work *up* from there; Feynman works
*down*, covering lots of the fascinating nitty-gritty stuff that he,
as a physicist, is interested in. So there is lots of material here that
is rarely found in computing texts, and certainly even more rarely found
in as accessible a form as this. And the lectures that are right down in
the physics -- on thermodynamically reversible computation and quantum
computing -- are some of today's hot topics: Feynman, as usual, was way
ahead of his time.

This is a write-up of a series of lectures Feynman gave at CalTech in
the mid 1980s, transcribed from tape recordings. So the chapters capture
the flavour of the great man's lecturing style, and the informality of the
spoken word. But although I am a great admirer of Feynman's, I don't think
the change of medium works too well in this case. I'd love to *hear*
these lectures, but when *reading*, I would prefer a deeper and more
polished form.
