Ibn al-Haitham.
The ancient Greeks thought our eyes emitted rays, like a laser, which enabled us to see.
The first person to realise that light enters the eye, rather than leaving it, was the 10th-century Muslim mathematician, astronomer and physicist Ibn al-Haitham.
He invented the first pin-hole camera after noticing the way light came through a hole in window shutters. The smaller the hole, the better the picture, he worked out, and set up the first Camera Obscura (from the Arab word qamara for a dark or private room).
He is also credited with being the first man to shift physics from a philosophical activity to an experimental one. |
