ABU RAIHAN MUHAMMAD AL-BIRUNI (973 - 1048 C.E.)
by
Dr. A. Zahoor
Al-Biruni was an outstanding astronomer, mathematician, physicist, Physician, geographer, geologist and historian. According to Max Meyerhoff, Al-Biruni is perhaps the most prominent figure in the phalanx of those universally learned Muslim scholars who characterize the Golden Age of Islamic Science. His great contributions in so many diverse fields earned him the title "al-Ustadh," the Master or Professor par excellence. Some historians have called the period of his activity as "The Age of Al-Biruni."
Abu Raihan Muhammad Al-Biruni was born in Khwarizm (now Kara-Kalpakskaya in present Uzbekistan) in 973 C.E. He studied Arabic, Islamic Law, and several branches of knowledge. Later, he learnt Greek, Syriac and Sanskrit. His knowledge of several languages helped him in understanding the available work and bring together a fresh and original approach in his work. Al-Biruni was of the view that whatever the subject one should use every available source in its original form, investigate the available work with objective scrutiny, and carry out research through direct observation and experimentation.
He was a contemporary of the famous physician Ibn Sina (Avicenna) and is known to have corresponded with him. Al-Biruni's contributions are so extensive that an index of his written works covers more than sixty pages. His scientific work combined with contributions of Al-Haitham (Al-Hazen) and other Muslim scientists laid down the early foundation of modern science. Al-Biruni died in 1048 C.E. in Ghazna (Afghanistan) after a forty-year illustrious career.
Al-Biruni made original and important contributions to science. He discovered seven different ways of finding the direction of the north and south, and discovered mathematical techniques to determine exactly the beginnings of the season. He also wrote about the sun and its movements and the eclipse. In addition, he invented few astronomical instruments. Many centuries before the rest of the world, Al-Biruni discussed that the earth rotated on its axis and made accurate calculations of latitude and longitude. These observations are contained in his book "Al-Athar Al-Baqia." He wrote a treatise on timekeeping in 1000 C.E.
Al-Biruni was the first to conduct elaborate experiments related to astronomical phenomena. He stated that the speed of light is immense as compared with the speed of sound. He described the Milky Way as a collection of countless fragments of the nature of nebulous stars. Al-Biruni described his observation of the solar eclipse of April 8, 1019 and the lunar eclipse of September 17, 1019. On the solar eclipse which he observed at Lamghan, a valley surrounded by mountains between the towns of Qandahar and Kabul, he wrote: ... at sunrise we saw that approximately one-third of the sun was eclipsed and that the eclipse was waning. He observed the lunar eclipse at Ghazna and gave precise details of the exact altitude of various well-known stars at the moment of first contact. Al-Biruni's book "Al-Tafhim-li-Awail Sina'at al-Tanjim" summarizes work on Mathematics and Astronomy. It was translated by Ramsay Wright in 1934, Luzac.
Al-Biruni contributions in Physics include work on springs and accurate determination of the specific weight of eighteen elements and compounds including many metals and precious stones. His book "Kitab-al-Jamahir" discusses the properties of various precious stones. He was a pioneer in the study of the angles and trigonometry. He worked on shadows and chords of circles and developed a method for trisection of an angle. He elaborated on the principle of position and discussed the Indian numerals.
