He was voiced by Alfred Molina in the episode. Given a light source and a spherical ball of certain refractive index, the closest point on the spherical ball where the light is refracted to the eye of the observer can be obtained by solving a tenth degree equation.
Alhazen's intromission theory followed al-Kindi and broke with Aristotle in asserting that "from each point of every colored body, illuminated by any light, issue light haxn color along every straight line that can be drawn from that point".
