Known for developing theories based on experimentation and data collection rather than abstract thought, Alhazen stressed the need to test results - especially those considered canon, as he wrote in his Doubts Against Ptolemy: "A person who studies scientific books with a view of knowing the real facts ought to turn himself into an opponent of everything he studies; he should thoroughly assess its main as well as its margin parts, and oppose it from every point of view and all its aspects. Alhazen made significant improvements in optics, physical science, and the scientific method. His most influential work is titled Kitāb al-Manāẓir (Arabic: كتاب المناظر, "Book of Optics"), written during 1011–1021, which survived in a Latin edition. Alhazen or Abu Ali al-Hasan ibn al-Hasan ibn al-Haytham was an Arab polymath born in the tenth century AD.

Ḥasan Ibn al-Haytham was an Arab mathematician, astronomer, and physicist of the Islamic Golden Age.
