Bill's own fascination with science began with a battered old schoolbook he had when he was about ten or eleven years old in America. It had an illustration that captivated him - a cutaway diagram showing Earth's interior as it would look if you cut into it with a large knife and carefully removed about a quarter of its bulk. And he very clearly remembers thinking: "How do they know that?"
Bill's story-telling skill makes the "How?" and, just as importantly, the "Who?" of scientific discovery entertaining and accessible for all ages. In this exciting edition for younger readers, he covers the wonder and mysteries of time and space, the frequently bizarre and often obsessive scientists and the methods they used, the crackpot theories which held sway for far too long, the extraordinary accidental discoveries which suddenly advanced whole areas of science when the people were actually looking for something else (or in the wrong direction) and the mind-boggling fact that, somehow, the universe exists and, against all odds, life came to be on this wondrous planet we call home.
