ABU ALI HASAN IBN AL-HAITHAM (ALHAZEN) (965 - 1040 AD) Al-Haitham, known in the West as Alhazen, is considered as the father of modern optics. Alhazen or Abu Ali al-Hasan ibn al-Hasan ibn al-Haytham was an Arab polymath born in the tenth century AD. All modern cameras​—and indeed the eye itself—​use the same physical principles as the camera obscura. . But Alhazen's creation of the scientific method is his most far-reaching achievement. Abu Ali al-Hasan ibn al-Haytham (Basra, 965 – Caïro, ±1040) was een Arabisch astronoom en wiskundige.In Europa was hij bekend als Alhazen, de Latijnse verbastering van Al-Hasan.. Leven.

His first method, the canonical method, involved Wilson's theorem, while his second method involved a version of the Chinese remainder theorem. His work with lenses led to the development and production of early eyeglasses, microscopes, and telescopes. Alhazen’s writings on the properties of lenses thus laid essential groundwork for European eyeglass makers who, by holding lenses one in front of another, invented the telescope and the microscope. Alhazen, by the name Ibn al-Haytham, is featured on the obverse of the Iraqi 10,000-dinar banknote issued in 2003, and on 10-dinar notes from 1982. Alhazen solved problems involving congruences using what is now called Wilson's theorem. We hebben dus veel aan hem te danken. ^ par. Archimedes had used this technique brilliantly to find the volume of a sphere.. Alhazen applied the method of exhaustion to the paraboloid and found he needed the formula for the sum of fourth powers to calculate the answer. An outstanding aspect of Alhazen’s work was his meticulous and systematic research into natural phenomena. His approach was most unusual for his day. TERMS OF USE The result? The scientific method is the foundation upon which researchers build. Fearing punishment from this notoriously unstable ruler, Alhazen pretended to be insane until the caliph died some 11 years later, in 1021.

According to author Jim Al-Khalili, Alhazen’s greatness is “not so much a consequence of any single revolutionary discovery . In his Opuscula, Alhazen considers the solution of a system of congruences, and gives two general methods of solution. *. Science and Reason, use them to guide your life. AWAKE! Alhazen's advice can be seen in action today around the world, from middle school science fairs to the Large Hadron Collider. He was one of the first investigators to test theories by experimentation, and he was not afraid to question accepted wisdom if the evidence did not back it up. He also studied visual  perception and the anatomy and mechanics of the eye. Observe. The man who laid the groundwork for it, however, is all but forgotten in the West.

His influence on physical sciences in general, and on optics in particular, has been held in high esteem and, in fact, ushered in a new era in optical research, both in theory and practice. However, of all of these, it is undoubtedly Ibn al-Haytham (965 – 1040 A.D,) often called Alhazan, who developed the scientific method most significantly. Rather, it is the way he taught us how to ‘do’ science.” His Book of Optics is described as “a real science textbook,” complete with precise descriptions of experiments, apparatuses, measurements taken, and results obtained. Later scientists buildt upon Alhazen's work. 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. In the meantime, Alhazen had plenty of leisure time to pursue other interests while confined for his feigned mental illness.
