Contributions of Abu al-Haytham

Why is Abu al-Haytham considered to be a titan among mathematicians even today?

          Abu al-Haythamm, a famous mathematician, astronomer and philosopher, made significant contributions to the principles of optics, astronomy, mathematics and meteorology. He seems to have written around 92 works of which, remarkably, over 55 have survived.
          The main topics on which he wrote were optics, including a theory of light and a theory of vision, astronomy, and mathematics, including geometry and numbers. His most important work is Kitab al-Manazir which contains the correct model of vision, and has a complete formulation of the laws of reflection as well as a detailed investigation of refraction.
           The book combines experiments with mathematical reasoning. In the field of mathematics, Abu al-Haytham worked on Euclid's theorems. He replaced some indirect proofs with direct proofs.
