The Science History Institute has teamed up with online learning platform Roundtable to offer you compelling courses from the history of science. This four-part course features James R. Voelkel, the Institute’s curator of rare books, who will cover the period in astronomy surrounding Copernicus’s proposal that the earth revolves around the sun.

The course is FREE, but registration is required.

Course Overview

The period between 1500 and 1725 is known as the “Scientific Revolution.” During this time, a group of beliefs, approaches, and activities that are recognizable as modern science emerged from something that was not. This course examines a key feature of that revolution, the slow recognition of the true nature of the solar system, that the earth was in motion and one of many planets orbiting the sun, and a transformation in astronomy and physics that made that understanding possible. Each session will be centered on significant and valuable scientific books by Copernicus, Tycho Brahe, Kepler, and Galileo.
