Al Haytham's Theory of Vision

The Greek Philosophers had long debated the nature of vision, without any definitive conclusion.  They were divided, between the belief that it was either a stimulus entering the eye or a visual ray projected from the eye.  This debate however, was finally settled by the great Hasan Ibn Al-Haytham, who developed the first modern theory of vision.  In this episode we explore Al-Haytham's optical work as one of the first great experimentalists who investigated the nature of light and his development of a new theory of perspective.
