How to Teach Relativity to Your Dog

In this title, the bestselling author of "How to Teach Quantum Physics to Your Dog" tackles Einsten's most famous theory - with the help of his faithful Alsatian, Emmy! In this highly anticipated follow-up book, popular physicist Chad Orzel explains relativity theory in a decidedly unscientific fashion - through a series of conversations with his dog, Emmy. It goes something like this: Emmy, the curious scamp that she is, typically pursues some half-understood aspect of science or maths as a means to catching bunnies or squirrels. You know, as dogs do. When she fails - or sometimes, even before she does - Orzel gently explains the flaws in her plan, followed by a more detailed explanation of the real physics for interested humans. Emmy, in true puppy fashion, provides some occasional (and always helpful) interjections, asking for clarification or commenting on the explanation offered. Readers can expect to learn such concepts as how length contraction causes fast-moving objects to shrink and how relativity causes moving clocks to run slow, along with some of the cosmological consequences of general relativity and what it can tell us about where the universe came from and how it will end. From relative motion and time dilation, to the unification of forces and extra dimensions, Orzel will have even the biggest physics-phobe hooked.
