As Kenneth W. Ford shows us in The Quantum World, the laws governing the very small and the very swift defy common sense and stretch our minds to the limit. Drawing on a deep familiarity with the discoveries of the 20th Century. Ford gives an appealing account of quantum physics that will help the serious reader make sense of a science that, for all its successes, remains mysterious. In response to the enthusiastic reception from physics teachers, Ford has also included a new section of Quantum Questions at the back of the book. The author will also publish a separate answer manual to these 300 questions that will be available to educators.
