Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham (Arabic: ابو علي، الحسن بن الحسن بن الهيثم, Persian: ابن هیثم, Latinized: Alhacen or (deprecated) Alhazen) (965 in Basra - c. 1039 in Cairo) was an Arab 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 (Arabic: البصري), after his birthplace in the city of Basra. He was also nicknamed Ptolemaeus Secundus ("Ptolemy the Second") or simply "The Physicist" in medieval Europe.

Born 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 madness and was placed under house arrest, during and after which he devoted himself to his scientific work until his death.

Did you know that the modern scientific method was first developed by Muslims?
Q. The modern scientific method was first developed in the Muslim world, where significant progress in methodology was made, especially in the works of Ibn al-Haytham (Alhazen) in the 11th century.[4] The most important development of the scientific method was the use of experiments to distinguish between competing scientific theories set within a generally empirical orientation. Ibn al-Haytham (Alhazen) is also known as the "father of optics" for empirically proving that vision occurred because of light rays entering the eye and for using a camera obscura to demonstrate the physical nature of light rays.[5] Ibn al-Haytham has also been described as the "first scientist" for his devlopment of the scientific method.[6] Source: Wikipedia The… [cont.]

A. that's interesting. What's more interesting is why the only science they embrace these days is the chemistry of bombmaking?

Camera Obscura Vs Pinhole Camera?! Please help?
Q. I gotta write a massive report on the history of photography. I have a list of questions i have to answer in the report, in designated chapters. I've already done one chapter on the Camera Obscura, writing about Alhazen and the such. Then i went onto Image capture. however, on my sheet it says 'Who invented the pinhole camera?' That would mean repeating myself from the camera obscura part, right? The Camera Obscura was essentially just an oversized Pinhole. So where would i start without repeating myself? I know that the pinhole was reinvented around 1600 and that David brewster took the first actual photography in 1850. Where do i say how it was invented? In the camera obscura part i mentioned how Robert Boyle and Robert Hooke made the… [cont.]

A. just remember that the Camera Obscura was used for painting while the pinhole camera uses actual chemical plates or photosensitive paper or film

Should Schools be allowed to teach Christian theories?
Q. If everyone wants schools and public places to be secular, sure - but would that include things like Scientific Method, which is a Christian/Islamic theory (R.Bacon/Alhazen), or The Big Bang theory, which is rightfully Catholic (Georges Lemaitre). The question is, if we are want freedom FROM religion, does that include Scienfic Method, and the Big Bang Theory, which had religious origins? Because if not, then Christmas (which had a religious origin: Pagan>Christian>Secular Materialst), no longer truly represents its origins, should be allowed to be celebrated in public places? For those who contend that "The Big Bang did not have religious origins" : Lemaitre himself also described his theory as "the Cosmic Egg exploding at the moment… [cont.]

A. Yes, if those theories have been accepted by the larger secular scientific community. Another interesting topic is "S'hould school teach religious literacy?" Real history has religion woven through and through. Real current events has religion woven through and through. A certain amount of religious literacy needs to be taught to the citizens of a country just so they will know what is going on in the world and more importantly why it is happening. It is ignorance and fear that causes most injustice and wars. I suggest you read the very good book "Religious Literacy: What Every American Needs to Know--And Doesn't" by Stephen Prothero With love in Christ.
