On his travels through time and space, he encounters a splendid collection of astonishingly eccentric, competitive, obsessive and foolish scientists, like the painfully shy Henry Cavendish who worked out many conundrums like how much the Earth weighed, but never bothered to tell More...anybody about many of his findings. In the company of such extraordinary people, Bill Bryson takes us with him on the ultimate eye-opening journey, and reveals the world in a way most of us have never seen it before.
