I want to know the answer to the following question:
What book did Ibn al-Haytham write?
All the background I'm provided with is that "This led to an early scientific method being developed in the Muslim world, where significant progress in methodology was made, beginning with the experiments of Ibn al-Haytham (Alhazen) on optics from c. 1000, in his Book of Optics.". Is that enough to answer the question?
