The adventure spans the world from Stonehenge to astronomically aligned pyramids at Giza, from Mayan observatories at Chichen Itza to the atomic clock in Washington, the world's official timekeeper since the 1960s. We visit cultures from Vedic India and Cleopatra's Egypt to Byzantium and the Elizabethan court; and meet an impressive cast of historic personages from Julius Caesar to Omar Khayyam, and giants of science from Galileo and Copernicus to Stephen Hawking. Our present calendar system predates the invention of the telescope, the mechanical clock, and the concept ol zero and its development is one of the great untold stories of science and history.

How did Pope Gregory set right a calendar which was in error by at least ten lull days? What did time mean to a farmer on the Rhine in 800 A.D.? What was daily life like in the Middle Ages, when the general population reckoned births and marriages by seasons, wars, kings'' reigns, and saints' days? In short, how did the world

Using the designing and building of the Clock of the Long Now as a framework, this is a book about the practical use of long time perspective: how to get it, how to use it, how to keep it in and out of sight. Here are the central questions it inspires: How do we make long-term thinking automatic and common instead of difficult and rare? Discipline in thought allows freedom. One needs the space and reliability to predict continuity to have the confidence not to be afraid of revolutions Taking the time to think of the future is more essential now than ever, as culture accelerates beyond its ability to be measured Probable things are vastly outnumbered by countless near-impossible eventualities. Reality is statistically forced to be extraordinary; fiction is not allowed this freedom This is a potent book that combines the chronicling of fantastic technology with equally visionary philosophical inquiry.

J.W. Dunne (1866-1949) was an accomplished English aeronautical engineer and a designer of Britian's early military aircraft. His An Experiment with Time, first published in 1927, sparked a great deal of scientific interest in--and controversy about--his new model of multidimensional time.

A series of strange, troubling precognitive dreams (including a vision of the then future catastrophic eruption of Mt. Pelee on the island of Martininque in 1902) led Dunne to re-evaluate the meaning and significance of dreams. Could dreams be a blend of memories of past and future events? What was most upsetting about his dreams was that they contradicted the accepted model of time as a series of events flowing only one way: into the future. What if time wasn't like that at all?

All of this prompted Dunne to think about time in an entirely new way. To do this, Dunne made, as he put it, an extremely cautious investigation in a rather novel direction. He wanted to outline a provable way of accounting for multiple dimensions and precognition, that is, seeing events before they happen. The result was a challenging scientific theory of the Infinite Regress, in which time, consciousness, and the universe are seen as serial, existing in four dimensions.

Astonishingly, Dunne's proposed model of time accounts for many of life's mysteries: the nature and purpose of dreams, how prophecy works, the immortality of the soul, and the existence of the all-seeing general observer, the Witness behind consciousness (what is now commonly called the Higher Self).

Here in print again is the book English playwright and novelist J.B. Priestley called one of the most fascinating, most curious, and perhaps the most important books of this age.

From the bestselling, National Book Award-nominated author of Genius and Chaos, a bracing new work about the accelerating pace of change in today's world.

An expert explores the riddle of subjective time, from why time speeds up as we grow older to the connection between time and consciousness.

We have widely varying perceptions of time. Children have trouble waiting for anything. ("Are we there yet?") Boredom is often connected to our sense of time passing (or not passing). As people grow older, time seems to speed up, the years flitting by without a pause. How does our sense of time come about? In Felt Time, Marc Wittmann explores the riddle of subjective time, explaining our perception of time--whether moment by moment, or in terms of life as a whole. Drawing on the latest insights from psychology and neuroscience, Wittmann offers a new answer to the question of how we experience time.

Wittmann explains, among other things, how we choose between savoring the moment and deferring gratification; why impulsive people are bored easily, and why their boredom is often a matter of time; whether each person possesses a personal speed, a particular brain rhythm distinguishing quick people from slow people; and why the feeling of duration can serve as an "error signal," letting us know when it is taking too long for dinner to be ready or for the bus to come. He considers the practice of mindfulness, and whether it can reduce the speed of life and help us gain more time, and he describes how, as we grow older, subjective time accelerates as routine increases; a fulfilled and varied life is a long life. Evidence shows that bodily processes--especially the heartbeat--underlie our feeling of time and act as an internal clock for our sense of time. And Wittmann points to recent research that connects time to consciousness; ongoing studies of time consciousness, he tells us, will help us to understand the conscious self.

Ishmael Reed has created a sharp, wildly funny slave's-eye view of the Civil War.

For centuries, scientists have strived to predict the future. But to what extent have they succeeded? Can past events-Hurricane Katrina, the Internet stock bubble, the SARS outbreak-help us understand what will happen next? Will scientists ever really be able to forecast catastrophes, or will we always be at the mercy of Mother Nature, waiting for the next storm, epidemic, or economic crash to thunder through our lives? In The Future of Everything, David Orrell looks back at the history of forecasting, from the time of the oracle at Delphi to the rise of astrology to the advent of the TV weather report, showing us how scientists (and some charlatans) predicted the future. How can today's scientists claim to anticipate future weather events when even thee-day forecasts prove a serious challenge? How can we predict and control epidemics? Can we accurately foresee our financial future? Or will we only find out about tomorrow when tomorrow arrives?

Clocks became common in late medieval Europe and the measurement of time began to rule everyday life. God's Clockmaker is a biography of England's greatest medieval scientist, a man who solved major practical and theoretical problems to build an extraordinary and pioneering astronomical and astrological clock. Richard of Wallingford (1292-1336), the son of a blacksmith, was a brilliant mathematician with a genius for the practical solution of technical problems. Trained at Oxford, he became a monk and then abbot of the great abbey of St Albans, where he built his clock. Although as abbot he held great power, he was also a tragic figure, becoming a leper. His achievement, nevertheless, is a striking example of the sophistication of medieval science, based on knowledge handed down from the Greeks via the Arabs.

Why do we measure time in the way that we do? Why is a week seven days long? At what point did minutes and seconds come into being? Why are some calendars lunar and some solar?
The organization of time into hours, days, months, and years seems immutable and universal, but is actually far more artificial than most people realize. For example, the French Revolution resulted in a restructuring of the French calendar, and the Soviet Union experimented with five and then six-day weeks.
Leofranc Holford-Strevens brings us this fascinating study of time using a range of examples from Ancient Rome and Julius Caesar's imposition of the Leap Year to the 1920's project for a fixed Easter. Those interested in time, history, and the development of the calendar will enjoy this absorbing exploration of an aspect of our lives that we all take for granted.
