The enigma of time has captivated science journalist Dan Falk, who sets off on an intellectual journey In Search of Time. The quest takes him from the ancient observatories of stone-age Ireland and England to the atomic clocks of the U.S. Naval Observatory; from the layers of geological “deep time” in an Arizona canyon to Albert Einstein’s apartment in Switzerland. Along the way he talks to scientists and scholars from California to New York, from Toronto to Oxford. He speaks with anthropologists and historians about our deep desire to track time’s cycles; he talks to psychologists and neuroscientists about the mysteries of memory; he quizzes astronomers about the beginning and end of time. Not to mention our latest theories about time travel — and the paradoxes it seems to entail. We meet great minds from Aristotle to Kant, from Newton to Einstein — and we hear from today’s most profound thinkers: Roger Penrose, Paul Davies, Julian Barbour, David Deutsch, Lee Smolin, and many more.
