Predating written language and marching on through human history, the desire for ever-better timekeeping has spurred technological innovation and sparked theories that radically reshaped our understanding of the universe and our place in it.
Chad Orzel, a physicist and bestselling author, continues his tradition of demystifying thorny scientific concepts by using the clocks and calendars central to our everyday activities as a jumping-off point to explore the science underlying the ways we keep track of our time. Ancient solstice markers depend on the basic astrophysics of our solar system; mechanical clocks owe their development to Newtonian physics; and the ultra-precise atomic timekeeping that enables GPS hinges on the predictable oddities of quantum mechanics.
Along the way, Orzel visits the delicate negotiations involved in Gregorian calendar reform, the intricate and entirely unique system employed by the Maya, and how the problem of synchronizing clocks at different locations ultimately required us to abandon the idea of time as an absolute and universal quantity. Sharp and engaging, A Brief History of Timekeeping is a story not just about the science of sundials, sandglasses, and mechanical clocks, but also the politics of calendars and time zones, the philosophy of measurement, and the nature of space and time itself.

Your alarm goes off, and you head to the kitchen to make yourself some toast and a cup of coffee. Little do you know, as you savor the aroma of the steam rising from your cup, that your ordinary morning routine depends on some of the weirdest phenomena ever discovered.
The world of quantum physics is generally thought of as hopelessly esoteric. While classical physics gives us the laws governing why a ball rolls downhill, how a plane is able to fly, and so on, its quantum cousin gives us particles that are actually waves, “spooky” action at a distance, and Schrodinger’s unlucky cat. But, believe it or not, even the most mundane of everyday activities is profoundly influenced by the abstract and exotic world of the quantum.
In Breakfast with Einstein, Chad Orzel illuminates the strange phenomena lurking just beneath the surface of our ordinary lives by digging into the surprisingly complicated physics involved in his (and anyone’s) morning routine. Orzel, author of How to Teach Quantum Physics to Your Dog, explores how quantum connects with everyday reality, and offers engaging, layperson-level explanations of the mind-bending ideas central to modern physics.

They say you can’t teach an old dog new tricks. But what about relativity?

Physics professor Chad Orzel and his inquisitive canine companion, Emmy, tackle the concepts of general relativity in this irresistible introduction to Einstein’s physics. Through armchair- and sometimes passenger-seat-conversations with Emmy about the relative speeds of dog and cat motion or the logistics of squirrel-chasing, Orzel translates complex Einsteinian ideas — the slowing of time for a moving observer, the shrinking of moving objects, the effects of gravity on light and time, black holes, the Big Bang, and of course, E=mc2 — into examples simple enough for a dog to understand.
A lively romp through one of the great theories of modern physics, How to Teach Relativity to Your Dog will teach you everything you ever wanted to know about space, time, and anything else you might have slept through in high school physics class.
