Everyone talks to their pets; Chad Orzel tells his about relativity.

2022 NATIONAL INDIE EXCELLENCE AWARDS WINNER — HISTORY: GENERAL ". . . inherently interesting, unique, and highly recommended addition to personal, professional, community, college, and academic library Physics of Time & Scientific Measurement history collections, and supplemental curriculum studies lists.” —Midwest Book Review "A wonderful look into understanding and recording time, Orzel’s latest is appropriate for all readers who are curious about those ticks and tocks that mark nearly every aspect of our lives." —Booklist “A thorough, enjoyable exploration of the history and science behind measuring time.” —Foreword Reviews It’s all a matter of time—literally. From the movements of the spheres to the slipperiness of relativity, the story of science unfolds through the fascinating history of humanity’s efforts to keep time. Our modern lives are ruled by clocks and watches, smartphone apps and calendar programs. While our gadgets may be new, however, the drive to measure and master time is anything but—and in A Brief History of Timekeeping, Chad Orzel traces the path from Stonehenge to your smartphone. 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. Orzel, a physicist and the bestselling author of Breakfast with Einstein and How to Teach Quantum Physics to Your Dog 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 (which still work perfectly 5,000 years later) 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. For those interested in science, technology, or history, or anyone who’s ever wondered about the instruments that divide our days into moments: the time you spend reading this book may fly, and it is certain to be well spent.

When it comes to science, too often people say "I just don't have the brains for it"--and leave it at that. Why is science so intimidating, and why do people let themselves feel this way? What makes one person a scientist and another disinclined even to learn how to read graphs? The idea that scientists are people who wear lab coats and are somehow smarter than the rest of us is a common, yet dangerous, misconception that puts science on an intimidating pedestal. How did science become so divorced from everyday experience? In Eureka, science popularizer Chad Orzel argues that even the people who are most forthright about hating science are doing science, often without even knowing it. Orzel shows that science is central to the human experience: every human can think like a scientist, and regularly does so in the course of everyday activities. The common misconception is that science is a body of (boring, abstract, often mathematical) facts. In truth, science is a process: Looking at the world, Thinking about what makes it work, Testing your mental model by comparing it to reality, and Telling others about your results--all things that people do daily. By revealing the connection between the everyday activities that people do--solving crossword puzzles, playing sports, or even watching mystery shows on television--and the processes used to make great scientific discoveries, Eureka shows that this process is one everybody uses regularly, and something that anyone can do.

A Sunday Times Book of the Year From the author of the international bestseller How to Teach Quantum Physics to Your Dog Your 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.

This reissued version of the classic text Basic Physics will help teachers at both the high-school and college levels gain new insights into, and deeper understanding of, many topics in both classical and modern physics that are commonly taught in introductory physics courses. All of the original book is included with new content added. Short sections of the previous book (174 in number) are labeled 'Features.' These Features are highlighted in the book, set forth in a separate Table of Contents, and separately indexed.Many teachers will value this book as a personal reference during a teaching year as various topics are addressed. Ford's discussions of the history and meaning of topics from Newton's mechanics to Feynman's diagrams, although written first in 1968, have beautifully withstood the test of time and are fully relevant to 21st-century physics teaching.

In this cleverly conceived book, physicist Robert Gilmore makes accessible some complex concepts in quantum mechanics by sending Alice to Quantumland-a whole new Wonderland, smaller than an atom, where each attraction demonstrates a different aspect of quantum theory. Alice unusual encounters, enhanced by illustrations by Gilmore himself, make the Uncertainty Principle, wave functions, the Pauli Principle, and other elusive concepts easier to grasp.

Monty is a dog, not a financial genius, but economics still shapes his everyday life. Over the course of seventeen walks, Dr Rebecca Campbell chews over economic concepts and investigates how they apply to our lives – people and mutts alike. There are no graphs, no charts (Monty can’t read them) and definitely no calculus! How to Teach Economics to Your Dog tackles the knotty question of what economics actually is. Is it a mathematical science like physics? Or a moral and philosophical investigation of how societies should manage scarce resources? Along the way we meet some of the great thinkers from Adam Smith to Thomas Piketty, and ponder questions such as: What on earth does quantitative easing mean? And why are some countries so much richer than others?
