What is the contribution of al-haitham in the field of physics?

Answer 1

Abu Ali al-Hasan ibn al-Hasan ibn al-Haytham (965 in Basra - c. 1040 in Cairo) was a prominent scientist and polymath from the 'Golden Age' of Muslim civilization. He is commonly referred to as Ibn al-Haytham, and sometimes as al-Basri, after his birthplace in the city of Basra. He is also known by his Latinized name of Alhzen or Alhacen.

Ibn al-Haytham made significant contributions to the principles of optics, as well as to physics, astronomy, mathematics, ophthalmology, philosophy, visual perception, and to the scientific method. He was also nicknamed Ptolemaeus Secundus ("Ptolemy the Second") or simply "The Physicist" in medieval Europe. Ibn al-Haytham wrote insightful commentaries on works by Aristotle, Ptolemy, and the Greek mathematician Euclid.
