In his book "The Philosophy of Light," the polymath Ibn al-Haytham commemorates his scientific revolution, which changed humanity's concept of vision and optics. Until the tenth century AD, it was widely believed that the eye emitted rays that fell on objects for vision. Ibn al-Haytham, with his experimental evidence and physical proofs, overturned this notion, proving that light travels from objects to the eye, thus establishing the modern science of optical physics. Ibn al-Haytham was not just a physicist; he was also a brilliant mathematician, physician, and engineer ahead of his time. He was interested in algebra, geometry, and ophthalmology, and he developed pioneering ideas for harnessing the waters of the Nile by constructing reservoirs to regulate irrigation. This work combines in-depth scientific research with the precision of experimental methodology, reflecting Ibn al-Haytham's genius as one of the icons of Arab-Islamic civilization who illuminated the path for modern science.
