Historical Eclipses & Earth's Rotation

Klappentext
A scientist who has studied eclipses for many years tells their story and explains their importance today.


Zusammenfassung
Eclipses of the Sun and Moon have attracted attention since the dawn of history. Long ago, chroniclers from Europe, Babylonia, China and the Arab lands penned graphic descriptions of them. Today, not only are these observations of historical interest; they have much to tell us about changes in the length of the day in the past due to tides and other causes.
