Astrophysicist George Smoot spent decades pursuing the origin of the cosmos, "the holy grail of science," a relentless hunt that led him from the rain forests of Brazil to the frozen wastes of Antarctica. In his search he struggled against time, the elements, and the forces of ignorance and bureaucratic insanity. Finally, after years of research, Smoot and his dedicated team of Berkeley researchers succeeded in proving the unprovable—uncovering, inarguably and for all time, the secrets of the creation of the universe. Wrinkles in Time describes this startling discovery that would usher in a new scientific age—and win Smoot the Nobel Prize in Physics.

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.

From H.G. Wells to Isaac Asimov to Ursula K. Le Guin, time travel has long been a favorite topic and plot device in tales of science fiction and fantasy. But as any true SF fan knows, astounding stories about traversing alternate universes and swimming the tides of time demand plausible science. That’s just what Paul J. Nahin’s guide provides. An engineer, physicist, and published science fiction writer, Nahin is uniquely qualified to explain the ins and outs of how to spin such complex theories as worm holes, singularity, and relativity into scientifically sound fiction. First published in 1997, this fast-paced book discusses the common and not-so-common time-travel devices science fiction writers have used over the years, assesses which would theoretically work and which would not, and provides scientific insight inventive authors can use to find their own way forward or backward in time. From hyperspace and faster-than-light travel to causal loops and the uncertainty principle and beyond, Nahin’s equation-free romp across time will help writers send their characters to the past or future in an entertaining, logical, and scientific way. If you ever wanted to set up the latest and greatest grandfather paradox—or just wanted to know if the time-bending events in the latest pulp you read could ever happen—then this book is for you.

One of TIME’s Ten Best Nonfiction Books of the Decade "Meet the new Stephen Hawking . . . The Order of Time is a dazzling book." --The Sunday Times From the bestselling author of Seven Brief Lessons on Physics, Reality Is Not What It Seems, Helgoland, and Anaximander comes a concise, elegant exploration of time. Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most readers this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it remains. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where at the most fundamental level time disappears. He explains how the theory of quantum gravity attempts to understand and give meaning to the resulting extreme landscape of this timeless world. Weaving together ideas from philosophy, science and literature, he suggests that our perception of the flow of time depends on our perspective, better understood starting from the structure of our brain and emotions than from the physical universe. Already a bestseller in Italy, and written with the poetic vitality that made Seven Brief Lessons on Physics so appealing, The Order of Time offers a profoundly intelligent, culturally rich, novel appreciation of the mysteries of time.

The instant New York Times Bestseller #1 Wall Street Journal Business Bestseller Instant Washington Post Bestseller "Brims with a surprising amount of insight and practical advice." --The Wall Street Journal Daniel H. Pink, the #1 bestselling author of Drive and To Sell Is Human, unlocks the scientific secrets to good timing to help you flourish at work, at school, and at home. Everyone knows that timing is everything. But we don't know much about timing itself. Our lives are a never-ending stream of "when" decisions: when to start a business, schedule a class, get serious about a person. Yet we make those decisions based on intuition and guesswork. Timing, it's often assumed, is an art. In When: The Scientific Secrets of Perfect Timing, Pink shows that timing is really a science. Drawing on a rich trove of research from psychology, biology, and economics, Pink reveals how best to live, work, and succeed. How can we use the hidden patterns of the day to build the ideal schedule? Why do certain breaks dramatically improve student test scores? How can we turn a stumbling beginning into a fresh start? Why should we avoid going to the hospital in the afternoon? Why is singing in time with other people as good for you as exercise? And what is the ideal time to quit a job, switch careers, or get married? In When, Pink distills cutting-edge research and data on timing and synthesizes them into a fascinating, readable narrative packed with irresistible stories and practical takeaways that give readers compelling insights into how we can live richer, more engaged lives.

The book's argument depends, as do most proposals in education, upon cer tain positions in the philosophy of education. I believe that education should be primarily concerned with developing understanding, with initiation into worth while traditions of intellectual achievement, and with developing capacities for clear, analytic and critical thought. These have been the long-accepted goals of liberal education. In a liberal education, students should come to know and appre ciate a variety of disciplines, know them at an appropriate depth, see the interconnectedness of the disciplines, or the modes of thought, and finally have some critical disposition toward what is being learned, to be genuinely open minded about intellectual things. These liberal goals are contrasted with goals such as professional training, job preparation, promotion of self-esteem, social engineering, entertainment, or countless other putative purposes of schooling that are enunciated by politicians, administrators, and educators. The book's argument might be consistent with other views of education especially ones about the training of specialists (sometimes called a professional view of education)-but the argument fits best with a liberal view of education. The liberal hope has always been that if education is done well, then other per sonal and social goods will follow. The development of informed, critical, and moral capacities is the cornerstone for personal and social achievements.
