Publisher's Summary

Bill Bryson has been an enormously popular author both for his travel books and for his books on the English language. Now, this beloved comic genius turns his attention to science. Although he doesn't know anything about the subject (at first), he is eager to learn, and takes information that he gets from the world's leading experts and explains it to us in a way that makes it exciting and relevant. Even the most pointy-headed, obscure scientist succumbs to the affable Bryson's good nature, and reveals how he or she figures things out. Showing us how scientists get from observations to ideas and theories is Bryson's aim, and he succeeds brilliantly. It is an adventure of the mind, as exciting as any of Bryson's terrestrial journeys.
