Ibn al-Haytham (Alhazen)

Optics + the scientific method

Ibn al-Haytham (Alhazen)

11th-century Arab polymath born in Basra; worked in Cairo.

Bragged he could regulate the Nile's flooding; when the caliph called his bluff, he faked insanity for a decade to avoid execution. Used the house arrest to write the Book of Optics — the first work to insist science needs controlled experiments AND mathematical proof. Modern science quietly starts with him.
