Born in Basra in 965, Ibn al-Haytham first studied theology, trying unsuccessfully to resolve the differences between the Shi'ah and Sunnah sects. Ibn al-Haytham then turned his attention to the works of the ancient Greek philosophers and mathematicians, including Euclid and Archimedes. He completed the fragmentary Conics by Apollonius of Perga. Ibn al-Haytham was the first person to apply algebra to geometry, founding the branch of mathematics known as analytic geometry.
A devout Muslim, Ibn al-Haitham believed that human beings are flawed and only God is perfect. To discover the truth about nature, Ibn a-Haitham reasoned, one had to eliminate human opinion and allow the universe to speak for itself through physical experiments. "The seeker after truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them," the first scientist wrote, "but rather the one who suspects his faith in them and questions what he gathers from them, the one who submits to argument and demonstration."
