If you’ve wondered what goes on in the minds of physicists, then try Fear of
Physics: A Guide for the Perplexed (Vintage, £7.99, ISBN 0 09 930113 X),
now out in paperback. Lawrence Krauss tells how scientists simplify problems and
make back-of-the-envelope estimates, and he explains why scientific creativity
is, in the words of Richard Feynman, “imagination in a straitjacket”. Often
funny and always human.
