Al-Hasan Ibn Al-Haytham, also known as Alhazen, was a prominent Arab scientist and mathematician born around 965 CE in Basra, Iraq. He is often referred to as the "father of optics" for his groundbreaking work in the study of light and vision. His most famous book, Book of Optics, laid the foundation for modern optics and introduced concepts such as the camera obscura. In addition to his contributions to optics, Ibn Al-Haytham made significant advancements in the fields of mathematics and physics. He emphasized the importance of experimentation and observation in scientific inquiry, which influenced later scientists during the Renaissance and beyond. His work remains relevant in various scientific disciplines today.
