Chad Orzel's treatment of special and general relativity is comprehensive, informative, and amazingly accessible, yet it's funny too. This is, by far, the most entertaining discussion of the subject that I've ever had the pleasure of reading. <p>Frank Close, author of The Infinity Puzzle <br> With Nero, the egocentric cat who believes it is the centre of the universe, and Emmy, the student dog whose questions and misunderstandings would drive any teacher to distraction, and whose interest in relativity is how E=mc DEGREES2 can turn squirrels into energy, Chad Orzel has created a delightful cast of characters to make his introduction to relativity relatively painless. A cleverly crafted and beautifully explained narrative that guides readers carefully into the depths of relativity. Whether you are a hare or a tortoise, or even a dog, you will enjoy this. Louisa Gilder, author of The Age of Entanglement For the price of a book, Orzel delivers the heady, joyful experience of taking a small college class with a brilliant and funny professor who really knows how to teach. A thoroughly winning romp through a rock-solid presentation of a beautiful subject. James Kakalios, Professor of Physics, University of Minnesota, and author of The Physics of Superheroes and The Amazing Story of Quantum Mechanics Move over, Krypto--there's a new superdog in town! Chad Orzel's dog Emmy, having mastered quantum physics, now helps us understand Einstein's theories of relativity in a deep and accessible way. Get this dog a cape! Jennifer Ouellette, author of The Calculus Diaries<br> Everyone's favorite physics-loving canine is back, this time giving us a dog's eye view of Einstein and relativity. Physics professor Chad Orzel leads Emmy (and us) through an engaging tour of light speed, time dilation, and amazing shrinking bunn
