iceageiscoming:malinchristersson:The difference between an easy model and a complicated one.Heliocentrism and geocentrismThe earliest recorded heliocentric model was proposed by Aristarchus of Stomas (~310-280 BCE), but in medieval Europe the geocentric model as championed by Aristotle and Claudius Ptolemy became popular. Nicolaus Copernicus (1473-1543 CE), Galileo Galilei (1564-1642 CE), and Johannes Kepler (1571-1630 CE) who was technically Tyche Brahe’s assistant (because sometimes you need a sugar daddy to have the funds to be a mathematician) eventually worked to establish heliocentrism in European science. As most people may know based on Galileo’s life, there was a religious motivation to reject the science of heliocentrism that helped make it unpopular. Medieval Islamic astrology, however, had already begun to question geocentrism in the 900s CE and multiple Muslim astronomers (Ibn Yunus, Ibn al-Haytham, Abu ‘Ubayd al-Juzjani, al-Sijzi, and more) wrote about how wrong it was by the 1050s CE.So, why is no one talking about geocentric-stan Nicolo di Genova meeting obviously heliocentric understanding Yusuf al-Kaysani and both of them thinking the other one is absolutely INSANE for believing the astronomic model that they do?? -- source link
