Famous Scientists of Uzbekistan
 
Abu Ali al - Husain ibn Abdallah ibn Sina
(AvicennaBorn: 980 in Kharmaithen 
(near Bukhara), Central Asia (now Uzbekistan). Died: June 1037 in Hamadan, 
Persia (now Iran). Ibn Sina or Avicenna was the most influential of all Islamic 
philosopher - scientists. He wrote on medicine as well as geometry, astronomy, 
arithmetic and music. Ibn Sina's two most important works are The Book of 
Healing and The Canon of Medicine. The first is a scientific encyclopaedia 
covering logic, natural sciences, psychology, geometry, astronomy, arithmetic and 
music. The second is the most famous single book in the history of medicine. Ibn 
Sina wrote about 450 works, of which around 240 have survived. Of the surviving 
works, 150 are on philosophy while 40 are devoted to medicine, the two fields in 
which he contributed most. He also wrote on psychology, geology, mathematics, 
astronomy, and logic. His most important work as far as mathematics is concerned, 
however, is his immense encyclopaedic work, the Kitab al - Shifa (The Book of 
Healing). One of the four parts of this work is devoted to mathematics and ibn Sina 
includes astronomy and music as branches of mathematics within the 
encyclopaedia. In fact he divided mathematics into four branches, geometry, 
astronomy, arithmetic, and music, and he then subdivided each of these topics. 
Geometry he subdivided into geodesy, statics, kinematics, hydrostatics, and optics; 
astronomy he subdivided into astronomical and geographical tables, and the 
calendar; arithmetic he subdivided into algebra, and Indian addition and 
subtraction; music he subdivided into musical instruments 
Abu Arrayhan Muhammad ibn Ahmad al - Biruni
Born: 15 Sept 973 in Kath, Khwarazm (now Khorezm province, Uzbekistan.) 
Died: 13 Dec 1048 in Ghazna (now Ghazni, Afganistan.) Al - Biruni is one of the 
major figures of Islamic mathematics. He contributed to astronomy, mathematics, 
physics, medicine and history. Abu Rayhan al - Biruni was born in Khwarazm, a 
region adjoining the Aral Sea now known as Karakalpakstan. The two major cities 
in this region were Kath and Jurjaniyya. Al - Biruni was born near Kath and the 
town were he was born is today called Biruni after the great scholar. He lived both 
in Kath and in Jurjaniyya as he grew up and we know that he began studies at a 
very early age under the famous astronomer and mathematician Abu Nasr Mansur. 
The total number of works produced by al - Biruni during his lifetime is 
impressive. It is estimated, that he wrote around 146 works with a total of about 
13,000 folios (a folio contains about the same amount as a printed page from a 
modern book). The range of al - Biruni’s works covers essentially the whole of 
science at his time
.
