Over the years, millions of school children must have written out their address in the same way -- their house number & street, their town, their country, their continent, planet Earth, the universe! Following this simplest of patterns, taking each line of the address as a starting point, Tim Radford explores our place in the scheme of things -- why we are attached to a particular geographical place & what significance do we have when faced with the realms of astronomy & astrophysics. Fascinating, entertaining & completely original, The Address Book tackles some of the most fundamental questions facing us, & allows us see ourselves completely afresh.
