Ali Qushiji, not the author of Hayy ibn Yaqdhan, is best known for the development of astronomical physics independent from natural philosophy.
Ala al-Dn Ali ibn Muhammed (1403  16 December 1474), known as Ali Qushji (Ottoman Turkish/Persian language:  , "kuu"  falconer in Turkish; Latin: "Ali Kushgii") was an astronomer, mathematician and physicist originally from Samarkand, who settled in the Ottoman Empire some time before 1472. 
 As a disciple of Ulugh Beg, he is best known for the development of astronomical physics independent from natural philosophy, and for providing empirical evidence for the Earth's rotation in his treatise, "Concerning the Supposed Dependence of Astronomy upon Philosophy". 
Ibn Tufail (c. 1105  1185) (full Arabic name:             "Abu Bakr Muhammad ibn Abd al-Malik ibn Muhammad ibn Tufail al-Qaisi al-Andalusi"; Latinized form: "Abubacer Aben Tofail"; Anglicized form: "Abubekar" or "Abu Jaafar Ebn Tophail") was a Moorish Andalusian Muslim polymath: a writer, novelist, Islamic philosopher, Islamic theologian, physician, astronomer, vizier, and court official. 
 It was partly a response to the philosophical novel "Hayy ibn Yaqdhan" by Andalusi writer Ibn Tufail.
