 This contemporary lack of scientific prominence is remarkable given that the Islamic world far exceeded European cultures in the range and quality of its scientific knowledge between approximately the ninth and the fifteenth century, excelling in domains such as mathematics (algebra and geometry, trigonometry in particular), astronomy (seriously considering, but not adopting, heliocentrism), optics, and medicine. These domains of knowledge are commonly referred to as “Arabic science”, to distinguish them from the pursuits of science that arose in the west (Huff 2003). “Arabic science” is an imperfect term, as many of the practitioners were not speakers of Arabic, hence the term “science in the Islamic world” is more accurate. Many scientists in the Islamic world were polymaths, for example, Ibn Sīnā (Avicenna, 980–1037) is commonly regarded as one of the most significant innovators, not only in philosophy, but also in medicine and astronomy. His Canon of Medicine, a medical encyclopedia, was a standard textbook in universities across Europe for many centuries after his death. Al-Fārābī (ca. 872–ca. 950), a political philosopher from Damascus, also investigated music theory, science, and mathematics. Omar Khayyám (1048–1131) achieved lasting fame in disparate domains such as poetry, astronomy, geography, and mineralogy. The Andalusian Ibn Rušd (Averroes, 1126–1198) wrote on medicine, physics, astronomy, psychology, jurisprudence, music, and geography, next to developing a Greek-inspired philosophical theology.
