Clock synchronisation is the backbone of applications such as high-accuracy satellite navigation, geolocation, space-based interferometry, and cryptographic communication systems. This title discusses the role of geometrical optics and antenna phase centre approximations in high accuracy work. It explores the clock synchronisation problem.

Follows the author's journey of self - and scientific discovery as he describes the physics that makes time travel possible. This book is a human memoir, and also a story of astonishing achievement.

The 5,000-year struggle to align the heavens with the clock and what happened to the missing ten days.

Full title: 'The Mayan Calendar and the Transformation of Consciousness'.

Presents the basics of astronomy required to understand sundials and describes how to design and build a classical sundial. This book shows the calculations involved in the sundial's construction and gives a comprehensive history of time measurement.

From the distinguished philosopher and historian of science Klaus Mainzer, a very brief history of the way we have come to understand, and not understand, time.

Why do we measure time in the way that we do? At what point did minutes and seconds come into being? This book explores time measurement and the organisation of time into hours, days, months and years using a range of examples, from Ancient Rome and Julius Caesar's Leap Year, to the 1920s' project for a fixed Easter.

With this 13-Moon Diary you can see at a glance what day it is, both according to the 'ordinary' 12-month Gregorian calendar as well as in the 13-Moon Calendar. You can find out its meaning and plan your activities accordingly. You can also learn to calculate your own personal 'Mayan horoscope'.

A work about the meaning of time, what it is, when it has started, how it flows and where to. It examines the consequences of Einstein's theory of relativity and offers suggestions about what research may reveal.

Albert Einstein remarked towards the end of his career that he only went to his office at Princeton 'just to have the privilege of walking home with Kurt Godel'. They had both fled Europe and the clutches of Nazism and found rare solace in each other's company in foreign exile.

Overturning many common perceptions of the past - for example, that clock time and the industrial revolution were intimately related - this unique historical study will engage all readers interested in how 'telling the time' has come to dominate our way of life.

Explores the idea of time travel from the first account in English literature to the theories of physicists such as Kip Thorne and Igor Novikov. This work covers topics such as: the history of time travel in fiction; the fundamental scientific concepts of time, spacetime, and the fourth dimension; and, much more.

Featuring two hundred images, this DVD includes geographic and regional detail, off-shore islands, and panoramic views of Australia from space.

Explores the changing ways in which time has been understood and how this knowledge is embedded in cultural practices. This title examines notions of time that extend from ancient mythology and classical philosophy to the contemporary social world of high-speed computer networks and globalized social relations.

Many philosophers, theologians, physicists and mathematicians have speculated on the nature of time. Recent scientific work is said to explain why time runs forward from past to future. But time still contains many mysteries - black holes, big bangs, asymmetries and relativities, arrows and loops.
