Al BIRUNI. 1. Al BIRUNI (973-1048) Al-Biruni was a versatile scholar and scientist who had equal facility in physics, metaphysics, mathematics, geography and history. Born in the city of Kheva near 'Ural' in 973 C.E. At an early age, the fame of his scholarship went around and when Sultan Mahmood Ghaznawi conquered his homeland, he took al-Biruni along with him in his journeys to India several times and thus he had the opportunity to travel all over India during a period of 20 years. He recorded observations of his travels through India in his well-known book Kitab al-Hind which gives a graphic account of the historical and social conditions of the sub-continent.

He observed that the Indus valley must be considered as an ancient sea basin filled up with alluvial. Al Beruni was the first scientist who had calculated and given the correct values of latitudes and longitudes of earth at various places. He was the first scientist who established the fact that the speed of light is far greater than the speed of sound. He also determined that the earth rotates along its axis and that is how days and nights are formed.

In order to determined the motion and position of earth, son, moon and various stars, he established with the help of Muslim states several well equipped astronomical observatories. It is amazing that he determined the diameter of earth centuries before the invention of the meteorological satellite. The value of the diameter of earth determined by Al- Biruni is found to be almost same as determined today by the modern meteorological satellite. The difference between the diameter of earth determined by Al- Biruni and that of satellite is of only few meters. It shows the accuracy of the method developed by Al- Biruni. It is a real tragedy that at present we do not know the exact method through which Al-Biruni had determined the diameter of earth.

Abu Ali Al Hussain ibn Abd Allah ibn Sina also known as Ibn Sina or Avicenna was a Persian Muslim astronomer, chemist, Hafiz, logician, mathematician, poet,.

Al Beruni wrote a number of books and treatises. On his return from India, al-Biruni wrote his famous book (Al-Qanun al-Masudi, fi al-Hai'a wa al-Nujum), The book discusses several theories of astronomy, trigonometry, solar, lunar, and planetary motions and relative topics. Al Beruni’s other books include: Kitab-al- Hind (History and Geography of India), Al-Athar al-Baqia (Ancient History and Geography), Kitab al-Saidana (Materia Medica) and Kitab al-Jawahir (Precious Stones) and his book Al-Tafhim-li-Awail Sina'at al-Tanjim (summary of mathematics and astronomy). He has been considered as one of the very greatest scientists of Islam, and, all considered, one of the greatest of all times. In his well-known book Al-Athar al-Baqia, Al Beruni has attempted a connected account of ancient history of nations and the related geographical knowledge. In this book, he has discussed the rotation of the earth and has given correct values of latitudes and longitudes of various places.

He has also made considerable contribution to several aspects of physical and economic geography in this book. His other scientific contributions include the accurate determination of the densities of 18 different stones. He also wrote the Kitab-al-Saidana, which is an extensive materia medica that combines the then existing Arabic knowledge on the subject with the Indian medicine. His book the Kitab-al-Jamahir deals with the properties of various precious stones. He was also an astrologer and is reputed to have astonished people by the accuracy of his predictions. He gave a clear account of numerals, elaborating the principle of position. Al Biruni developed a method for trisection of angle and other problems which cannot be solved with a ruler and a compass alone.

Al-Biruni discussed, centuries before the rest of the world, the question whether the earth rotates around its axis or not. He was the first to undertake experiments related to astronomical phenomena. He ascertained that as compared with the speed of sound the speed of light is immense. He explained the working of natural springs and artesian wells by the hydrostatic principle of communicating vessels. His investigations included description of various monstrosities, including that known as 'Siamese' twins. He observed that flowers have 3,4,5,6, or 18 petals, but never 7 or 9.
