The first theory, the emission theorywas supported by such thinkers as Euclid and Ptolemywho believed that sight worked by the eye emitting rays of light. Do you mean this John Dunn? He inserts a discussion of the perception of lunar and solar eclipses based on the assumption that the moon and sun are solid physical bodies.
Experiments with mirrors and the refractive interfaces between air, water, Alhazen ibn al haytham glass cubes, hemispheres, and quarter-spheres provided the foundation for his theories on catoptrics. It is unjustified to be too emphatic about his originality until more is known about his predecessors.
In the discussion of the nature of vision at the beginning of Optics, he argues that light physically affects the eye, citing the pain experienced by looking directly at the Sun and the afterimage experienced by staring at fire and then looking into a weakly illuminated place.
In short you are just desperate to push your POV, while ignoring academic sources that prove you wrong. These events were happening while ibn al-Haytham was a young boy growing up in Basra. These qualifications should be demonstrable to other people. He wrote over a hundred books, more than half of which have been preserved.
However, after personally reconnoitering near the southern border of Egypt, Ibn al-Haytham confessed his inability to engineer such a project. Who was Ibn al-Haytham?
Alhazen's work on optics is credited with contributing a new emphasis on experiment. Warum wir nichts verstehen und trotzdem Grosses schaffen in German 1. The eye physically receives only the rays of light and color, but the mind interprets the patterns produced on the glacial humor as certain forms at certain distances.
A Latin translation of the Kitab al-Manazir was made probably in the late twelfth or early thirteenth century. His methodology of investigation, in particular using experiment to verify theory, shows certain similarities to what later became known as the modern scientific method. Other manuscripts are preserved in the Bodleian Library at Oxford and in the library of Leiden.
Winter, a British historian of science, summing up the importance of Ibn al-Haytham in the history of physics wrote: The Kitab al-Manazir Book of Optics describes several experimental observations that Alhazen made and how he used his results to explain certain optical phenomena using mechanical analogies.
The explanation is based on the idea that light is a movement which admits a variable speed being less in denser bodies Truth is sought for itself [but] the truths, [he warns] are immersed in uncertainties [and the scientific authorities such as Ptolemy, whom he greatly respected are] not immune from error The interactive exhibit offers audiences the chance to step inside the mind and the world of Ibn al-Haytham and experience how we see and learn about the fundamentals of light science.
Kansas Bear says the historians must be specifically of Islamic studies, and uses this reason to delete the sourced material.
One of the mathematical problems which ibn al-Haytham attacked was the problem of squaring the circle. During the Middle Ages his books on cosmology were translated into Latin, Hebrew and other languages.
The two blue lunes together have the same area as the green right triangle. Tim Hidge has also published: Ibn al-Haytham's study of refraction led him to propose that the atmosphere had a finite depth of about 15 km.to measure the angular position of a fixed star, tracking that star from its rising to its zenith.

Hasan Ibn al-Haytham (Latinized Alhazen / ˌ æ l ˈ h ɑː z ən /; full name Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham أبو علي، الحسن بن الحسن بن الهيثم; c. – c. ) was an Arab mathematician, astronomer, and physicist of the Islamic Golden Age.
Al-Hassan Ibn al-Haytham (Latinised as Alhazen), born Basra, died Cairo. Born around a thousand years ago in present day Iraq, Al-Hasan Ibn al-Haytham (known in the West by the Latinised form of his first name, initially “Alhacen” and later “Alhazen”) was a pioneering scientific thinker who made important contributions to the understanding of [ ].
Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham (Arabic: أبو علي، الحسن بن الحسن بن الهيثم ), frequently referred tae as Ibn al-Haytham (Arabic: ابن الهيثم, Laitinised as Alhazen or Alhacen; c. – c. ), wis an Arab polymath an filosofer who made signeeficant contreibutions tae the principles.
Alhazen or Alhacen or ibn al-Haytham (–) was a pioneer of modern optics. Some have also described him as a "pioneer of the modern scientific method " and "first scientist ", but others think this overstates his contribution.
