Ibn al Haytham - Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham, Born in Basra Iraq in 965. Known in the West as Alhazen, Alhacen, or Alhazeni, he was the first person to test hypotheses with verifiable experiments, developing the scientific method more than 200 years before European scholars learned of it.He made significant contributions to the principles of optics, as well as to anatomy, astronomy, engineering, mathematics, medicine, ophthalmology, philosophy, physics, psychology, visual perception, and to science in general with his early application of the scientific method.
In his massive study of light and vision, Kitâb al-Manâzir (Book of Optics ), Ibn al-Haytham submitted every hypothesis to a physical test or mathematical proof. To test his hypothesis that "lights and colors do not blend in the air," for example, Ibn al-Haytham devised the world's first camera obscura, observed what happened when light rays intersected at its aperture, and recorded the results. Throughout his investigations, Ibn al-Haytham followed all the steps of the scientific method.
Richard Powers nominated Ibn al-Haytham's scientific method and scientific skepticism as the most influential idea of the second millennium.
Recipient of the Nobel Prize in Physics Abdus Salam considered Ibn-al-Haytham "one of the greatest physicists of all time".
George Sarton, the father of the history of science, wrote that "Ibn Haytham's writings reveal his fine development of the experimental faculty" and considered him "not only the greatest Muslim physicist, but by all means the greatest of mediaeval times".
Robert S. Elliot considers Ibn al-Haytham to be "one of the ablest students of optics of all times".
The author Bradley Steffens considers him to be the "first scientist".
and Professor Jim Al-Khalili also considers him the "world's first true scientist".
