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.Show book

Written in a non-technical style by two archaeologists and experienced writers about the past, the story begins with human origins in Africa some six million years ago and the spread of our remote ancestors across the Old World. Then we return to Africa and describe the emergence of Homo sapiens (modern humans) over 300,000 years ago, then, much later, their permanent settlement of Europe, Eurasia, Asia, and the Americas. From hunters and foragers, we turn to the origins of farming and animal domestication in different parts of the world after about 11,000 years ago and show how these new economies changed human existence dramatically. The narratives chronicle the rise and fall of civilizations, and the devastating effects of long droughts on many of them. The closing chapter poses a question: Why is world prehistory important in the modern world? What does it tell us about ourselves? Providing a simple, but entertaining and stimulating, account of the prehistoric past from human origins to today from a global perspective, World Prehistory: The Basics is the ideal guide to the story of our early human past and its relevance to the modern world.Show book
