Chad Orzel – författare

‘Entertaining and engrossing’ Sean CarrollPress the snooze button on your alarm once too often and you soon remember the importance of good timekeeping. That need to tell the time connects you to over five thousand years of human history, from the first solstice markers at Newgrange to quartz crystal oscillating in your watch today. Science underpins time: measuring the movement of Sun, Earth and Moon, and unlocking the mysteries of quantum mechanics and relativity theory – the key to ultra-precise atomic clocks.Yet time is also socially decided: the Gregorian calendar we use today came out of fraught politics, while the ancient Maya used sophisticated astronomical observations to produce a calendar system unlike any other. In his quirky and accessible style, Chad Orzel reveals the wondrous physics that makes time something we can set, measure and know.

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.

A Sunday Times Book of the YearFrom the author of the international bestseller How to Teach Quantum Physics to Your DogYour humble alarm clock, digital cameras, the smell of coffee, the glow of a grill, fibre broadband, smoke detectors… all hold secrets about quantum physics.Beginning at sunrise, Chad Orzel reveals the extraordinary science that underpins the simplest activities we all do every day, from making toast to shopping online. It’s all around us, the wonderful weirdness of quantum – you just have to know where to look.

The international bestseller from the author of Breakfast with Einstein‘Elegantly approachable descriptions... with a refreshing emphasis on recent research. Highly satisfying.’ GuardianEmmy is no ordinary dog. When adopted from the shelter by physics professor Chad Orzel, she becomes immediately fascinated by his work. Could she use quantum tunnelling to get through the neighbour’s fence? How about diffracting round a tree to chase squirrels? Or using virtual particles to catch bunnies made of cheese?Taking Emmy’s anarchic behaviour as a starting point, Orzel explains the key theories of quantum physics. From quarks and gluons to Heisenberg’s uncertainty principle, this is a uniquely entertaining way to unlock the secrets of the universe.
