Chad Orzel is a professor, blogger, and author of five popular-audience books about physics. _How to Teach Quantum Physics to Your Dog_ and _How to Teach Relativity to Your Dog_ explain modern physics through imaginary conversations with his German Shepherd, Emmy, and have been translated into more than a dozen languages. _Eureka! Discovering Your Inner Scientist_ explains how we use scientific thinking in pursuit of common hobbies and other activities. _Breakfast With Einstein_ explains how quantum phenomena show up in the course of an ordinary morning routine. And his latest, _A Brief History of Timekeeping_ looks at the science and technology behind the last several thousand years of human efforts to track the passage of time. He has a BA in Physics from Williams College and a Ph.D. in Chemical Physics from the University of Maryland, College Park, where he did his thesis research in the laboratory of William D. Phillips (1997 Nobel laureate in Physics) at the National Institute of Standards and Technology, studying collisions between laser-cooled xenon atoms less than a millionth of a degree above absolute zero. He then spent two years as a post-doc at Yale University in the group of Mark Kasevich, studying quantum effects in a Bose-Einstein Condensate. In 2001 he joined the faculty of Union College in Schenectady, NY, where he is now an Associate Professor in the Department of Physics and Astronomy. He lives in Niskayuna, NY with his wife, Kate Nepveu, their two children, and new dog Charlie the pupper.
