About this audiobook

A biography of Ibn al-Haytham that follows optics, geometry, astronomy, experiment, doubt, and textual transmission from Basra and Cairo to later Arabic and Latin readers.

Why it's worth a listen

It explains a genuine transformation in optics while resisting the easy label inventor of the scientific method and the dramatic certainty of late Nile stories.

A question to keep

How did Ibn al-Haytham make vision a problem of light, geometry, anatomy, and controlled testing rather than a story about rays leaving the eye?
