How do we measure time? As the Millennium approaches great significance will be placed on the symbolism of midnight on 31 December Greenwich Mean Time. But what is the history of time and how do we measure it? This Gem, building on the exhibition at the Greenwich Observatory, tells the story of time, tracking the variety of different ways that have been used to measure time from Egyptian water clocks and speculation about the significance of prehistoric sites through the calendar changes to the international standard definition of time based upon the vibration of a caesium atom. Heavily illustrated both with diagrams and artifacts, the history of time is brought alive. It is the first of a continuing series of Gems on issues in popular science.

paperback. Etat : Very Good. Most of our very good books have only minor imperfections such as shelf wear consistent with a new book that's sat on a bookshop shelf for a year or two. Occasionally we may miss other minor imperfections as we have to grade books at speed. Our books are dispatched from a Yorkshire former cotton mill. We list via barcode/ISBN so please note that the images are stock images and may not be the exact copy you receive, furthermore the details about edition and year might not be accurate as many publishers reuse the same ISBN for multiple editions and as we simply scan a barcode or enter an ISBN we do not check the validity of the edition data when listing. If you're looking for an exact edition please don't order (at least not without checking with us first, although we don't always have time to check). We aim to dispatch prompty, the service used will depend on order value and book size. We can ship to most countries, see our shipping policies. Payment is via Abe only.
