Famous Scientists of Uzbekistan
 
Muhammad Musa Al-KHWARAZMI (Al-Khwārizmī) : born around 783, 
at Khwarezm in Greater Khorasan (modern Xorazm Region, Uzbekistan). He died 
around 
850 
at 
Bagdad. 
He 
was 
a Persian mathematician, astronomer and geographer during 
the Abbasid 
Caliphate, a scholar in the House of Wisdom, Academy of Sciences located 
in Baghdad. 
formerly Latinized as Algoritmi, 
was 
In 
the 
12th 
century, Latin translations 
of his 
work on 
the Indian 
numerals introduced 
the decimal positional number system to the Western world. Al-Khwārizmī’s The 
Compendious Book on Calculation by Completion and Balancing presented the 
first systematic solution of linear and quadratic equations in Arabic. In 
Renaissance Europe, he was considered the original inventor ofalgebra, although it 
is now known that his work is based on older Indian or Greek sources. He 
revised Ptolemy‘s Geography and wrote on astronomy and astrology. 
Some words reflect the importance of al-Khwārizmī’s contributions to 
mathematics. “Algebra” is derived from al-jabr, one of the two operations he used 
to 
solve quadratic 
equations. Algorism and algorithm stem 
from Algoritmi, 
the Latin form of his name. His name is also the origin of (Spanish) guarismo[ and 
of (Portuguese) algarismo, both meaning digit. 
Al-Khwārizmī’s 
contributions 
to mathematics, geography, astronomy, 
and cartography established the basis for innovation in algebra and trigonometry. 
His systematic approach to solving linear and quadratic equations led to algebra, a 
word derived from the title of his 830 book on the subject, “The Compendious 
Book on Calculation by Completion and Balancing”.
