Geosentrisme: Perbedaan antara revisi

Dikarenakan dominansi ilmiah sistem Ptolemaik dalam astronomi Islam, para astronom Muslim menerima bulat model geosentrik.{{refn|group=n|"Semua astronom Islam dari Thabit ibn Qurra pada abad ke-9 sampai Ibn al-Shatir pada abad ke-14, dan semua filsuf alamiah dari al-Kindi sampai Averroes dan seterusnya, diketahui telah menerima ... gambaran dunia menurut budaya Yunani yang terdiri dari dua bulatan, di mana salah satunya, bulatan selestial ... secara bulat membungkus yang lain."<ref>{{cite journal |first= A.

The "Maragha Revolution" refers to the Maragha school's revolution against Ptolemaic astronomy. The "Maragha school" was an astronomical tradition beginning in the [[Maragheh observatory|Maragha observatory]] and continuing with astronomers from the [[Umayyad Mosque|Damascus mosque]] and [[Ulugh Beg Observatory|Samarkand observatory]]. Like their [[Al-Andalus|Andalusian]] predecessors, the Maragha astronomers attempted to solve the [[equant]] problem (the circle around whose circumference a planet or the center of an [[epicycle]] was conceived to move uniformly) and produce alternative configurations to the Ptolemaic model without abandoning geocentrism. They were more successful than their Andalusian predecessors in producing non-Ptolemaic configurations which eliminated the equant and eccentrics, were more accurate than the Ptolemaic model in numerically predicting planetary positions, and were in better agreement with empirical observations.<ref name="Saliba1994">{{cite book |last= Saliba |first= George |authorlink= George Saliba |year= 1994 |title= A History of Arabic Astronomy: Planetary Theories During the Golden Age of Islam |url= https://archive.org/details/historyofarabica0000sali |pages= [https://archive.org/details/historyofarabica0000sali/page/233 233]–234, 240 |publisher= [[New York University Press]] |isbn= 0814780237}}</ref> The most important of the Maragha astronomers included [[Mo'ayyeduddin Urdi]] (d. 1266), [[Nasīr al-Dīn al-Tūsī]] (1201–1274), [[Qutb al-Din al-Shirazi]] (1236–1311), [[Ibn al-Shatir]] (1304–1375), [[Ali Qushji]] (c. 1474), [[Al-Birjandi]] (d. 1525), and Shams al-Din al-Khafri (d. 1550).<ref name="Dallal1999">{{cite book |first= Ahmad |last= Dallal |year= 1999 |chapter= Science, Medicine and Technology |title= The Oxford History of Islam |url= https://archive.org/details/oxfordhistoryofi00john |page= [https://archive.org/details/oxfordhistoryofi00john/page/171 171] |editor-first= John |editor-last= Esposito |editor-link= John Esposito |location= New York |publisher= [[Oxford University Press]]}}</ref> [[Ibn al-Shatir]], the Damascene astronomer (1304–1375 AD) working at the [[Umayyad Mosque]], wrote a major book entitled ''Kitab Nihayat al-Sul fi Tashih al-Usul'' (''A Final Inquiry Concerning the Rectification of Planetary Theory'') on a theory which departs largely from the Ptolemaic system known at that time. In his book, "Ibn al-Shatir, an Arab astronomer of the fourteenth century," E. S. Kennedy wrote "what is of most interest, however, is that Ibn al-Shatir's lunar theory, except for trivial differences in parameters, is identical with that of [[Nicolaus Copernicus|Copernicus]] (1473–1543 AD)." The discovery that the models of Ibn al-Shatir are mathematically identical to those of Copernicus suggests the possible transmission of these models to Europe.<ref name="Guessoun2008">{{cite journal |last= Guessoum |first= N. |date=June 2008 |title= Copernicus and Ibn Al-Shatir: Does the Copernican revolution have Islamic roots? |journal= The Observatory |volume= 128 |pages= 231–9}}</ref> At the Maragha and [[Ulugh Beg Observatory|Samarkand observatories]], the [[Earth's rotation]] was discussed by al-Tusi and [[Ali Qushji]] (b. 1403); the arguments and evidence they used resemble those used by Copernicus to support the Earth's motion.<ref name="Ragep2001a">{{Cite journal |last= Ragep |first= F.
