Korte beschrijving: The Calendar and its History:
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 skilful 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.
Allsky-camera
Met een allsky-camera (voorzien van een fish-eye lens) wordt de volledige hemel boven de sterrenwacht voortdurend in de gaten gehouden. Dit levert vaak mooie en spectaculaire beelden.
