The ABC of Relativity is Bertrand Russell's most
brilliant work of scientific popularisation. With
marvellous lucidity he steers the reader who has no
knowledge of maths or physics through the subtleties
of Einstein's thinking; in easily assimilable steps he
explains the theories of special and general relativity
and describes their practical application (among much
else to discoveries about gravitation and the invention
of the hydrogen bomb).
'Einstein', wrote Russell, 'revolutionised our
conception of the physical world, but the innumerable
popular accounts of his theory generally cease to be
intelligible at the point where they begin to say
something important.'
The basic principles of relativity have not changed
since Russell first published his lucid guide for the
general reader. This new edition takes account of the
extension of our knowledge about the theory and its
applications.
