  • Astronomy in Medieval Islam
    • Greek Astronomy
      • Ptolemy's work offered Islam knowledge to help their society grow
        • geometry allowed them to predict the movements of the sun, moon, and stars. This was used to have an accurate lunar calendar and determine timings of their prayers
          • astronomers were able to sort out the problems with Ptolemy's work
            • Ptolemy had observed solar eccentricity and solar apogee from 4 points but this was inaccurate. The islamic astronomers found it was easier to be more accurate when using two points and corrected Ptolemy's issues
      • If it were not for Arabic translations most of the work from the greeks would have been lost
        • They also commented on the texts and added their own thoughts and ideas
          • Learning from mistakes of the past they were able to make their own work
        • They also made corrections of the work and because the amount of time had passed they had more knowldge and were able to make things more accurate
          • It also made people question ptolmemy's work and the greek astronomy legacy
            • Idea
            • Idea
      • Islamic scientists found the greek astronomy was filled with cosmological absudities
        • They thought of themselves as the reformers of that astronomy and creators of an alternative without contradictions
          • It took Islamic astronomers generations to figure out what the problems were and then generations after to solve them. This would lead to a new theory of astronomy that would benefit Copernicus' idea
    • al-Din al-Urdi
      • The theorem now called Urdi lemma, could reproduce the apparent motions of the planets with a deferent that moved uniformly in place around an axis that passed through its center
        • Later on, Copernicus uses this to account for planetary motions in his heliocentric cosmology
    • Ibn al-Shatir wrote an archaic manuscript on astronomy in 14th century Umayyad
      • It anticipated some ideas of copernicus more than 100 years before he was born
        • There was a connection between the two. Copernicus got some information from medieval Islam
        • Idea
      • Ibn al-Shatir questioned the nature of Aristotle's ether
        • He said: If everything in the heavens was made of ether how was it that the starts emitted light and the carry spheres did not? To answer this question he said: that could not be as simple as people had said it was.
          • The composition of ether was more complex than people thought.
          • by including epicycles into this theory, he managed to construct geocentic models that were consistent with this new vision of Aristotelian cosmology
