Alhazen (Ibn al-Haytham) – The Father of Optics

In this episode of Science Giants, we travel to 11th-century Cairo to encounter Alhazen, the scholar who transformed how we see light and vision. Through painstaking experiments, he proved that sight comes from rays entering the eye, not beams cast from it. His Book of Optics set the stage for the scientific method itself, combining theory with observation and testing. Alhazen’s legacy runs through the work of later giants from Kepler to Newton, making him one of the great bridges between ancient science and modern inquiry.
