Jim Al-Khalili鈥檚 Black Holes, Worm Holes and Time Machines is
another of the many books about the wonders of the Universe and what we know
about them. But with a difference, though. Enthusiasm to make everything
understandable to the most untutored comes from every page. It鈥檚 successful,
it鈥檚 humorous and it鈥檚 up to date. A great crib for furtive, refreshing use.
