Albert Einstein's celebrated remark that 'God does not play dice' was
his response to a set of new scientific ideas now known as quantum
physics. These theories threatened the ordered determinism of the
Newtonian universe, presenting the radical challenge of an unstable
world disturbed by our very attempts to measure or observe it. One of
the prime fascinations of quantum physics is precisely the great
conceptual leap it requires us to make from our conventional ways of
thinking about the physical world. It introduces instead the alarming
possibilities that the observer's mind is the only reality, or that
there may be parallel universes. Alternatively, its very contradictions
may suggest that despite its manifest successes, quantum physics still
leaves us in need of a further revolution in thought and the final
complete theory of the physical universe. Alastair Rae's introductory
exploration has been hailed as 'a masterpiece of clarity', and offers an
engaging guide to the theories on offer.
