The Heavenly ChallengeDownloadable Audiobook - 2006
Astronomy is perhaps the oldest science. The ancients saw cosmic meanings in the stars, and they organized their lives around lunar and solar cycles (i.e. the month and year). They also observed the solstices, the equinoxes, and of course the four seasons. Over many centuries the "precession of the equinoxes" corrupted Julius Caesar's ancient calendar (the Julian calendar); in 1586 it was replaced with the Gregorian calendar, which features the system of leap years we know today.
