Ibn al-Haytham.

Abu Ali Al Hassan Bin Al Hassan Bin Al Haytham (965 AD - 1040 AD) is a Muslim scholar who has made significant contributions to mathematics, optics, physics, astronomy, engineering, ophthalmology, philosophy, visual perception and science in general, using his scientific method. Confirmed by modern science.

Ibn al-Haitham corrected some of the prevailing concepts at the time based on the theories of Aristotle, Ptolemy and Euclid. Ibn al-Haytham proved that light comes from objects to the eye, not the reverse, as was believed at that time. And explained the functions of its members, the first to study the effects and psychological factors of sight. His comparative book also included a fourth-order equation on the reflection of light on spherical mirrors, still known as the "Ibn al-Haytham question".
Ibn al-Haytham is the first founder of the field of science and a pioneer of the scientific method. He is also one of the first experimental physicists who dealt with the results of observations and experiments only in an attempt to explain them mathematically without resorting to other experiments.
Ibn al-Haytham moved to Cairo where he lived most of his life, and there it is mentioned that by his knowledge of mathematics he can regulate the Nile floods. Then, the ruling Fatimid Caliph ordered him to carry out his ideas. However, Ibn al-Haytham was quickly shocked by the impossibility of implementing his ideas, and he changed his mind, and for fear of his life he claimed madness, so he was forced to stay at home. Then, Ibn al-Haytham devoted his life to his scientific work until his death.
