History of Science: Antiquity to 1700

Copernicus and Calendrical Reform (1x26)

:

The Scientific Revolution is considered to commence with the 1543 publication of Copernicus's On the Revolutions of the Heavenly Orbs, which promoted a Sun-centered rather than Earth-centered cosmos. This lecture looks at the content and reception of Copernicus's ideas, its effects on astronomy and physics, and at a related development, the reform of the calendar under Pope Gregory XIII.
