Facts About Ibn al-Haytham

Ibn al-Haytham was a prolific writer who composed no less than 44 treatises on physics, philosophy, astronomy, mathematics, medicine and other subjects. Many of these works were produced from a modest room in the college-mosque of al-Azhar provided to him by the Fatimid state. One of Ibn al-Haytham’s remarkable achievements was a detailed description of the human eye and the functions of its various parts. He also wrote on the propagation of light and colours, optical illusions and reflections, spherical and parabolic mirrors, shadows and eclipses, the rainbow and the halo. He was one of the earliest scholars to recognise gravity as a force and knew correctly the relations between the motion, space and time of falling bodies. Most of his scientific writings are of a highly mathematical character and based on his own experiments and calculations.

Ibn al-Haytham was a genuine scientist who made new discoveries in the physical universe. His greatest contribution was in the field of optics, for which he is called the “father of optics”. All the current ideas about light, optics and ophthalmology are founded upon his observations and findings. According to the historian of science, George Sarton, Ibn al-Haytham is the greatest Muslim physicist and one of the great opticians of all time. By his emphasis on precise observation and experimentation, he anticipated the empirical approach of European scientists in the modern era.
