Opis

This fascinating book draws together a wealth of diverse material on the much-trusted (and rarely disputed) phenomenon we know as the calendar. From the fundamentals of astronomy to the world's ancient time-keeping schemes, to the development of the modern-day calendar, to the precise calculation of when specific dates occur (as in how one arrives at the date for Easter Sunday), this is a skillful yet approachable discussion of the calendar from both the historical and contemporary perspectives. Readers will even learn how to perform experiments and calculations for themselves by using such basic techniques as stargazing and simple mathematics.

Recenzje

This is a work of enthusuastic research.....Ricahrds makes even the most arcane complications arrising from the accident of the Earth's spin and orbit seem fascinating

O autorze

E. G. (Edward Graham) Richards was formerly a Senior Lecturer in the Department of Biophysics at King's College, University of London. His interest in the calendar was sparked when he wrote and published computer programmes for converting dates from one calendar to another. An historical note on the various calendars included in the exercise was intended to accompany the programmes but as the author's appetite for knowledge about the calendars grew, so did the note. It eventually became, after many years of research, this book. Dr Richards and his wife live in London.
