IBN AL-HAYTHAM Known in the West as Alhazen , Alhacen , or Alhazeni , I bn al-Haytham was the first person to test hypotheses with verifiable experiments, developing the scientific method more than 200 years before European scholars learned of itby reading his books. He was also nicknamed Ptolemaeus Secundus (" Ptolem y the Second") . Ibn al-Haytham is regarded as the father of modern optics for his influential Book of Optics ( Kitb al-Manzir ). ( 965 in Basra - c. 1039 in Cairo )
2. Ibn al-Haytham proved that light travels in straight lines using the scientific method by carrying out various experiments with lenses , mirrors , refraction , and reflection in his Book of Optics (1021). Ibn al-Haytham was a pioneer in many areas of science, making significant contributions in varying disciplines. His pioneering work on number theory, analyti c geometry, and the link between algebra and geometry, also had an influence on Ren Descartes's (1596-1650) geometric analysis and Isaa ...more

Anyone who has ever used vision glasses or contact lenses, taken a picture with a camera or watched television has a reason to be thankful to the Father of Optics, Alhazen.Latinized as Alhazen, in full, Ab Al al-asan ibn al-Haytham, born c. 965, Basra, Iraq, died c. 1040, Cairo, Egypt, according to Encyclopedia Britannica, mathematician and astronomer who made significant contributions to the principles of optics and the use of scientific experiments.
David L. Shenkenberg writes in an article titled, Before Newton, there was Alhazen, for Photonix.com:

A millennium ago, an Arab scientist authored more than 100 works on optics, astronomy, mathematics and religious philosophy. Although he was arguably one of the greatest scientists of all time, his name is little known to people living in Western countries today.

If we read all the works of Alhazen, Roger Bacon from 14th century and Sir Isaac Newton side by side, we may realize that a lot of work attributed to Sir Isaac Newton tru ...more

Ab Al al-asan ibn al-asan ibn al-Haytham (965 in Basra c. 1040 in Cairo) was a MuslimMuslimscientist and polymath described in various sources as either Arabic or Persian.Alhazen 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 also wrote insightful commentaries on works by Aristotle, Ptolemy, and the Greek mathematician Euclid.

He is frequently referred to as Ibn al-Haytham, and sometimes as al-Basri after his birthplace in the city of Basra. He was also nicknamed Ptolemaeus Secundus ("Ptolemy the Second")[14] or simply "The Physicist" in medieval Europe.

Born circa 965, in Basra, present-day Iraq, he lived mainly in Cairo, Egypt, dying there at age 74.[14] Over-confident about practical application of his mathematical knowledge, he assumed that he could regulate the floods of the Nile. After being ordered by Al-Hakim bi-Amr Allah, the sixth ...more

HE made significant contributions to the principles of optics, as well as to anatomy, astronomy, engineering, mathematics, medicine, ophthalmology, philosophy, physics, psychology, visual perception, and to science in general with his introduction of the scientific method.

Ibn al-Haytham is regarded as the "father of modern optics" for his influential Book of Optics, which correctly explained and proved the modern intromission theory of vision, and for his experiments on optics, including experiments on lenses, mirrors, refraction, reflection, and the dispersion of light into its constituent colours. He studied binocular vision and the moon illusion, described the finite speed[] and rectilinear propagation of light and and argued that rays of light are streams of corpuscular energy particles[16]travelling in straight lines.] Due to his formulation of a modern quantitative, empirical and experimental approach to physics and science, he is considered the pioneer of the modern scientif ...more
