Bored during Mass at the cathedral in Pisa, the seventeen-year-old Galileo regarded the chandelier swinging overhead--and remarked, to his great surprise, that the lamp took as many beats to complete an arc when hardly moving as when it was swinging widely. Galileo's Pendulum tells the story of what this observation meant, and of its profound consequences for science and technology.

The principle of the pendulum's swing--a property called isochronism--marks a simple yet fundamental system in nature, one that ties the rhythm of time to the very existence of matter in the...

Time, it has been said, is the enemy. In an era of harried lives, time seems increasingly precious as hours and days telescope and our lives often seem to be flitting past. And yet, at other times, the minutes drag on, each tick of the clock excruciatingly drawn out. What explains this seeming paradox?

Based upon a full decade's empirical research, Michael G. Flaherty's new book offers remarkable insights on this most universal human experience. Flaherty surveys hundreds of individuals of all ages in an attempt to ascertain how such phenomena as suffering, violence, danger, boredom,...

This fascinating work begins with a scientific appraisal of time and its relationship with 3D space. It explains in clear, understandable language, the complex theories of such famous men as Newton, Einstein, and Stephen Hawking. Is time infinite, or does it have a beginning and an end? Do Black Holes and White Vortices distort time, or penetrate it? The authors also analyse and evaluate puzzling, well documented reports of time travel and reincarnation, and strange cases of deja vu. Can time travel account for such anachronistic discoveries as a 20th century sparkplug found encased among...

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...

The treatment of time in quantum mechanics is still an important and challenging open question in the foundation of the quantum theory.

This multi-authored book, written as an introductory guide for newcomers to the subject, as well as a useful source of information for the expert, covers many of the open questions. The book describes the problems, and the attempts and achievements in defining, formalizing and measuring different time quantities in quantum theory.
