During many years living in Egypt, ten of which were spent under what we may now call protective custody (house arrest), he composed one of his most celebrated works, the Kitab al-Manazir, whose title is commonly translated into English as Book of Optics but more properly has the broader meaning Book of Vision. He sought experimental proof of his theories and ideas. He was one of the earliest scientists to study the characteristics of light and the mechanism/process of vision. Ibn al-Haytham was born in the year 965 in Basra, and died in about 1040 in Cairo. ” By this he meant it was essential to conduct experiments to test what is written rather than blindly accepting it as true. “If learning the truth is the scientist’s goal… then he must make himself the enemy of all that he reads. Ibn al-Haytham’s work was remarkable for its emphasis on proof and evidence. الحسن بن الهيثم Ibn al-Haytham, pioneering scientist In an area that spread from Spain to China, inspirational men and women, of different faiths and cultures, built upon knowledge of ancient civilisations, making discoveries that had a huge and often underappreciated impact on our world. Ibn al-Haytham was born during a creative period known as the golden age of Muslim civilisation that saw many fascinating advances in science, technology and medicine. Today, many consider him a pivotal figure in the history of optics and the “Father of modern Optics”. Through his Book of Optics (Kitab al-Manazir) and its Latin translation (De Aspectibus), his ideas influenced European scholars including those of the European Renaissance. His methodology of investigation, in particular using experiment to verify theory, shows certain similarities to what later became known as the modern scientific method.
