What is time? When did we first use it? Does it always work? How do animals tell time? A fun and fascinating look at time from the first calendars and clocks to the digital watches and precise time-keeping methods of today.

Sam Faulkner travels back in time to medieval Scotland, ancient Egypt, and Renaissance Bruges in search of his missing father.

One of Smithsonian Magazine's Ten Best History Books of 2021 A captivating, surprising history of timekeeping and how it has shaped our world. For thousands of years, people of all cultures have made and used clocks, from the city sundials of ancient Rome to the medieval water clocks of imperial China, hourglasses fomenting revolution in the Middle Ages, the Stock Exchange clock of Amsterdam in 1611, Enlightenment observatories in India, and the high-precision clocks circling the Earth on a fleet of GPS satellites that have been launched since 1978. Clocks have helped us navigate the world and build empires, and have even taken us to the brink of destruction. Elites have used them to wield power, make money, govern citizens, and control lives—and sometimes the people have used them to fight back. Through the stories of twelve clocks, About Time brings pivotal moments from the past vividly to life. Historian and lifelong clock enthusiast David Rooney takes us from the unveiling of al-Jazari’s castle clock in 1206, in present-day Turkey; to the Cape of Good Hope observatory at the southern tip of Africa, where nineteenth-century British government astronomers moved the gears of empire with a time ball and a gun; to the burial of a plutonium clock now sealed beneath a public park in Osaka, where it will keep time for 5,000 years. Rooney shows, through these artifacts, how time has been imagined, politicized, and weaponized over the centuries—and how it might bring peace. Ultimately, he writes, the technical history of horology is only the start of the story. A history of clocks is a history of civilization.

Using a series of games, puzzles and activities, this book helps children learn how to tell time, both traditional and digital time-keeping, and understand the passing of time. Included is a fold-out clockface with movable hands and information on how people told the time long ago.

T is for a Time Alphabet uses poetry and expository text to explore the concept of time, from explaining basic units of measurement to showcasing important scientific achievements. Topics include famous inventors (Albert Einstein and John Harrison) and important structures and landmarks (Kulkulkan Pyramid and Big Ben). Budding scientists will discover what world-famous stone structure is believed to be an early calendar, follow the voyages of explorer Ferdinand Magellan to better understand the International Date Line, and learn to tell time using the Zulu time system.

Explains how to tell time and discusses such aspects of time as day and night, days of the week, and months of the year. Includes a fold-out clock face for practice.

You don’t have to be a victim of time any longer. No matter how much we try to plan ahead and organize our to-do lists, everyone seems to face the same universal struggle: there’s never enough time. But what if time, that supposedly linear, inevitable phenomenon, isn’t what you think it is? What if you could actually have all the time in the world—and more? With her groundbreaking book, All the Time in the World, researcher Lisa Broderick reveals the new science of time so you can master it for yourself. Drawing from physics, quantum law, and psychological theory, Broderick will help you shift your fixed constructs around time into something more fluid and malleable. Then, with dozens of step-by-step practices, you’ll learn to put theory into action and become the master of your own experience of time. Highlights include: • Learn powerful, science-based practices for stretching and bending time to meet your personal needs • Understand the quantum laws that govern our experience of time • Explore the moments you’ve already felt time “slowing down”—and learn to consciously create this experience on demand • Why time is not the unchanging linear property of human experience we believe it to be • Flow states and getting in the zone—how to alter your perceptions, increase focus, and accomplish your goals • Healing the past by “time traveling” through your perceptions • How “experiencing your life in advance” can help you manifest the future outcomes • Discover why upgrading your relationship with time is the secret to creating the reality you desire and living without limitations “Our ability to influence our experience of time is the key to doing what we are here to do,” writes Broderick. “As you liberate yourself from the illusion of time as we know it, you will become a confident creator of your own reality. You have all the time in the world.”
