Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham (, Persian: Alhazen) (965 in Basra – c. 1040 in Cairo) was a PersianArab scientist and polymath He made significant contributions to the principles of optics, as well as to physics, anatomy, astronomy, engineering, mathematics, medicine, ophthalmology, philosophy, psychology, visual perception, and to science in general with his early application of the scientific method. He is sometimes called al-Basri , after his birthplace in the city of Basra. He was also nicknamed Ptolemaeus Secundus ("Ptolemy the Second" or simply "The Physicist in medieval Europe. Alhazen wrote insightful commentaries on works by Aristotle, Ptolemy, and the Greek mathematician EuclidBorn circa 965, in Basra, Iraq and part of Buyid Persia at that time] he lived mainly in Cairo, Egypt, dying there at age 76] 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 ruler of the Fatimid caliphate, to carry out this operation, he quickly perceived the impossibility of what he was attempting to do, and retired from engineering. Fearing for his life, he feigned madnesswas placed under house arrest, during and after which he devoted himself to his scientific work until his death.
ABOUT ROGER BACOM:
In the 13th century, Robert Grosseteste and Roger Bacon commented on the pinhole camera. Between 1000 and 1600, men such as Ibn al-Haytham, Gemma Frisius, and Giambattista della Porta wrote on the pinhole camera, explaining why the images are upside down. Pinhole devices provide safety for the eyes when viewing solar eclipses because the event is observed indirectly, the diminished intensity of the pinhole image being harmless compared with the full glare of the Sun itself.
