Born in Basra (Iraq) in 965 and died in Cairo (Egypt) in 1039-1041 (this last date is not known exactly), Ibn Al-Haytham is a great physicist, humanist, one of the greatest engineers that humanity has produced and specialist in optics. He is considered by many historians of science to be the first true scientist in the modern sense of the term. He lived in Iraq before going to Egypt following the request of the Fatimid Sultan Al Hakim to honor his court and compete with the Abbasid dynasty of Baghdad and Umayyads in Cordoba.

He was given every means and was given the task of controlling the floods of the Nile that struck Egypt. After a long period of exploration, he realized that it was impossible to achieve what the Sultan was asking him to do. He prefers then to simulate madness rather than admit the failure of his mission. Interned in his cell, he devoted himself to his research work in several disciplines such as astronomy, geometry, physics and many others. He is the epitome of those Arab scholars who have brilliantly cultivated the local, Greek and Indian heritage. Legend has it that on a sunny day, the guardian of his cell decided to dig a hole to see what Ibn-Haytham was doing, a ray of light entered through this little hole. This was the beginning of the demystification of the fundamental laws of optics and the study of the physiology of the eye.

Before continuing the adventure of his discoveries, let us go back to the ancient optics (Ptolemy's). The current model at the time was based on the idea of ​​a visual ray (hypothetical entity made to see) that came out of the center of the eye in the form of a cone to explore the exterior and material environments.

The genius and great invention of Ibn Al-Haytham is to have reversed the meaning. Except that by inverting the meaning, that is by saying that the light enters the eye, he had to invent something that was not taken into account as a physical object at the time: the light. He had to show that the light entered the eye, passed through an optic nerve and that there was a kind of image transmitted by the back of the lens that went directly to the brain. He understood that things were happening inside the body, thus breaking the ancient thought where vision was seen as an external phenomenon occurring outside the human body (via the visual ray). He later studied the halos of light, the rainbow and explained the deformations of the sun on the horizon by atmospheric refraction.
