Book Description
"If you lie awake worrying about the overnight transition from December 31, 1 b.c., to January 1, a.d. 1 (there is no year zero), then you will enjoy Duncan Steel's Marking Time."--American Scientist "No book could serve as a better guide to the cumulative invention that defines the imaginary threshold to the new millennium."--Booklist A Fascinating March through History and the Evolution of the Modern-Day Calendar . . . In this vivid, fast-moving narrative, you'll discover the surprising story of how our modern calendar came about and how it has changed dramatically through the years. Acclaimed author Duncan Steel explores each major step in creating the current calendar along with the many different systems for defining the number of days in a week, the length of a month, and the number of days in a year. From the definition of the lunar month by Meton of Athens in 432 b.c. to the roles played by Julius Caesar, William the Conqueror, and Isaac Newton to present-day proposals to reform our calendar, this entertaining read also presents "timely" tidbits that will take you across the full span of recorded history. Find out how and why comets have been used as clocks, why there is no year zero between 1 b.c. and a.d. 1, and why for centuries Britain and its colonies rang in the New Year on March 25th. Marking Time will leave you with a sense of awe at the haphazard nature of our calendar's development. Once you've read this eye-opening book, you'll never look at the calendar the same way again.

Book Description
Telling time becomes clear and easy for young readers in this bright and lively introduction to measurements of time. From seconds to minutes, hours to days, exploring what time is and discovering why we need to tell time, helps young readers understand more than 'the big hand is on the one and the little hand is on the two'. Megan Halsey’s playful illustrations depict imaginative digital and analog clocks that range in design. With the help of a whole lot of clocks, a dash of humor, and a few familiar circumstances, learning to tell time is a lot of fun. It's about time.

Book Description
The uses of time in astronomy - from pointing telescopes, coordinating and processing observations, predicting ephemerides, cultures, religious practices, history, businesses, determining Earth orientation, analyzing time-series data and in many other ways - represent a broad sample of how time is used throughout human society and in space. Time and its reciprocal, frequency, is the most accurately measurable quantity and often an important path to the frontiers of science. But the future of timekeeping is changing with the development of optical frequency standards and the resulting challenges of distributing time at ever higher precision, with the possibility of timescales based on pulsars, and with the inclusion of higher-order relativistic effects. The definition of the second will likely be changed before the end of this decade, and its realization will increase in accuracy; the definition of the day is no longer obvious. The variability of the Earth's rotation presents challenges of understanding and prediction. In this symposium speakers took a closer look at time in astronomy, other sciences, cultures, and business as a defining element of modern civilization. The symposium aimed to set the stage for future timekeeping standards, infrastructure, and engineering best practices for astronomers and the broader society. At the same time the program was cognizant of the rich history from Harrison's chronometer to today's atomic clocks and pulsar observations. The theoreticians and engineers of time were brought together with the educators and historians of science, enriching the understanding of time among both experts and the public.

Book Description
Perpetual calendars are a fascinating way to look at time, and can be defined in a variety of ways. In a comprehensive how-to manual, James Saltvold shares valuable insight on how to use his unique concepts to make practical perpetual calendars for everyday home and office use. These calendars, which save resources and look like a conventional calendar, can be set to display any month for any year within their range. They are set by simply moving a slider, and typically have a range of 50 to 100 years. Saltvold uses skills he acquired during an engineering career to present design ideas and concepts for calendars that are easy to produce and use. After providing a brief description of the four types or categories that his calendars fi t into, Saltvold leads readers on an informative journey, enhanced by figures and tables. He explains how to bring calendar prototypes into mass production, describes products that can be made from the four types of perpetual calendars, details which products might be attractive to various markets and manufacturers, and shares a brief history of his own work in developing concepts and researching patents. Additional sections include material on where to search for more information on perpetual calendars, as well as references with comments. Practical Perpetual Calendars includes designs for desk calendars, wall calendars, pocket calendars, photo holders, and other applications. The calendars shown on the front cover are described on the following pages: wall calendar (p. 129), clock (p. 77), pocket calendar (p. 68), full-year calendar (p. 157), 7-column desk calendar (p. 145), and 13-column desk calendar (p. 120).

Book Description
"I well recall a conversation with an executive I hoped to interview about her astonishing productivity. I began our call with an assurance that I would not take much of her time. She laughed. 'Oh, I have all the time in the world,' she said." Most of us feel constantly behind, unsure how to escape feeling oppressed by busyness. Laura Vanderkam, unlike other time-management gurus, believes that in order to get more done, we must first feel like we have all the time in the world. Think about it: why haven't you trained for that 5K or read War and Peace? Probably because you feel beaten down by all the time you don't seem to have. In this book, Vanderkam reveals the seven counterintuitive principles the most time-free people have adopted. She teaches mindset shifts to help you feel calm on the busiest days and tools to help you get more done without feeling overwhelmed. You'll meet people such as... ♦ An elementary school principal who figured out how to spend more time mentoring teachers, and less time supervising the cafeteria ♦ An executive who builds lots of meeting-free space into his calendar, despite managing teams across multiple continents ♦ A CEO who does focused work in a Waffle House early in the morning, so he can keep an open door and a relaxed mindset all day ♦ An artist who overcame a creative block, and reached new heights of productivity, by being more gentle with herself, rather than more demanding The strategies in this book can help if your life feels out of control, but they can also help if you want to take your career, your relationships, and your personal happiness to the next level. Vanderkam has packed this book with insights from busy yet relaxed professionals, including "time makeovers" of people who are learning how to use these tools. Off the Clock can inspire the rest of us to create lives that are not only productive, but enjoyable in the moment.
