@tomeclarke @cm_richards FYI: We credit Copernicus for getting the heliocentric view of the work right, but his orbits were all wrong -- they were circles and not ellipses, giving bad answers. The basic idea was good, but needed further modification. Something common in science. https://t.co/8T8jDm2hA9 — PolitiTweet.org
