Lead

Insofar as Alhazen used the Aristotelician intromission realist theory of sight, I wonder how one could claim that his optics "correctly explained the process of sight for the first time." Maybe another formulation would be better (except if you believe that the image projected by an object is than transmitted to the eye and then to the brain without any translation or coding...

Many problems

There is much in this article that seems overly favourable to Ibn al-Haytham.

For example, Ibn al-Haytham was the first to discover that the celestial spheres do not consist of solid matter is nonsense. The celestial spheres don't exist; they are part of a long-discarded theory. ...and he also discovered that the heavens are less dense than the air. Well no, he didn't. He asserted it. And since the heavens are essentially a vacuum, he was wrong about that too. Notice how the astronomy section contradicts the scientific-method section.

he developed a method for determining the general formula for the sum of any integral powers, which was fundamental to the development of infinitesimal and integral calculus does not sound at all believable.

He speculated on electromagnetic aspects of light Are we really supposed to believe that?

This is Nikola Tesla all over again...

The article is also repetitive and seems to have suffered from cut-n-paste: His book Kitab al-Manazir (Book of Optics) was translated... - oh dear, someone has forgotten we are in the BoO article!

What you believe is not important. Go ahead and read the all 6 chapters of his book and show that he in fact has not done these things. Or demand that these claims are backed with references that could be reached. —Preceding unsigned comment added by 171.65.95.195 (talk) 23:05, 17 February 2009 (UTC)[reply]

Wouldn't he also be called Persian rather than Iraqi, or at least something like "Persian (present-day Iraq)" ? —Preceding unsigned comment added by 68.97.122.105 (talk) 06:35, 26 August 2008 (UTC)[reply]

The entire article is written as a love letter to Ibn al-Haytham. The entire article need a serious rewrite, because as it stands it is a blight on Wikipedia. This specific page was used as an example of the poor scholarship of Wikipedia by one of my son's teachers, and he was very correct. Supertheman (talk) 05:08, 13 May 2009 (UTC)[reply]

Tags

I hung the tags on the article as most of it is about the author and his other works not the book. I plan on "hacking" out everthing not about the book its selfJ8079s (talk) 21:15, 11 July 2009 (UTC)[reply]

Composition Date

Composition date listed here appears to be wrong. A.I. Sabra (arguably the foremost scholar of this period) places its composition "at any rate, after AD 1028." See Sabra, A.I. 2003. "Ibn al-Haytham's Revolutionary Project in Optics: The Achievement and the Obstacle." In The Enterprise of Science in Islam: New Perpesctives, The MIT Press. Quote from page 90.
