Short Summary
Alhazen, also known as Ibn al-Haytham, was a pioneering Arab scientist born in the 10th century, renowned for his groundbreaking work in optics, mathematics, and astronomy. His most significant contribution was the development of the scientific method, which laid the groundwork for modern experimental science. Alhazen's extensive research on light and vision revolutionized the understanding of optics, earning him the title of "Father of Optics." His influential book, "Kitab al-Manazir" or "The Book of Optics," profoundly impacted both the Islamic Golden Age and the later European Renaissance.
Early Life & Education
Born in 965 in Basra, in present-day Iraq, Alhazen spent his early years in a region known for its rich intellectual and cultural environment. His full name was Abu Ali al-Hasan ibn al-Hasan ibn al-Haytham. He received a comprehensive education in various subjects, including mathematics and philosophy, which were integral to the Islamic educational curriculum of the time. His early life in Basra was marked by exposure to diverse scholarly works, which ignited his passion for scientific inquiry. As a young man, Alhazen moved to Cairo, where he continued his studies and began his illustrious career.
Career Highlights
Alhazen's career was characterized by significant contributions to the fields of optics, mathematics, and astronomy. His tenure in Cairo saw the development of his most famous work, "The Book of Optics," in which he meticulously described the behavior of light and the principles of vision. He challenged the prevailing theories of the time, proposing that vision occurs when light reflects off an object and enters the eye. His work extended to the study of lenses, mirrors, and refraction, significantly advancing the understanding of optical science. Alhazen's methodical approach to experimentation and observation set a new standard for scientific research.
