On 2nd of the Islamic month of Rajab in 440 AH, the prominent Iranian Islamic scientist, Abu Rayhan Mohammad ibn Ahmad al-Berouni, passed away in the city of Ghazni, in present day Afghanistan at the age of 77. He was a multisided genius and wrote prolifically on history, geography, mathematics, astronomy, mineralogy, and various other topics. He wrote over 180 books. His work on geometry, arithmetic, trigonometry, and algebra, is titled "at-Tafhim" in which he has calculated the weight of objects.
He was born in Khwarezm, a region adjoining the Aral Sea and presently in Uzbekistan. Beiruni, who was a follower of the Prophet’s Ahl al-Bayt, has written about the spherical shape of the Earth and its revolving on its axis as it orbits round the Sun, several centuries before Europeans were to discover these facts. He was conversant in Arabic, Persian, Greek and Sanskrit, and after visiting India and spending several months in the company of its sages, he wrote the valuable book, “Tahqiq ma lil-Hind”.
The books written by him include “Kitab Sina‘at at-Tanjim” (The Book of Elements of the Art of Astronomy, and “Aasaar al-Baqiyah an-il-Qoroun al-Khaliya” (The Remaining Signs of Past Centuries), which is a comparative study of calendars of different cultures and civilizations, interlaced with mathematical, astronomical, and historical information. He also wrote the “Qanoun al-Mas'oudi”, an extensive encyclopedia on astronomy, geography, and engineering.
