MATHEMATICIANS from Turkmenistan

Top 2

The following people are considered by Pantheon to be the most legendary Turkmen Mathematicians of all time. This list of famous Turkmen Mathematicians is sorted by HPI (Historical Popularity Index), a metric that aggregates information on a biography’s online popularity.

1. Muhammad ibn Musa al-Khwarizmi (780 - 850)

With an HPI of 86.03, Muhammad ibn Musa al-Khwarizmi is the most famous Turkmen Mathematician.  His biography has been translated into 140 different languages on wikipedia.

Muhammad ibn Musa al-Khwarizmi (Persian: محمد بن موسى خوارزمی; c. 780 – c. 850), or simply al-Khwarizmi, was a Persian polymath who produced vastly influential Arabic-language works in mathematics, astronomy, and geography. Around 820 CE, he was appointed as the astronomer and head of the House of Wisdom in Baghdad, the contemporary capital city of the Abbasid Caliphate. His popularizing treatise on algebra, compiled between 813–833 as Al-Jabr (The Compendious Book on Calculation by Completion and Balancing),: 171  presented the first systematic solution of linear and quadratic equations. One of his achievements in algebra was his demonstration of how to solve quadratic equations by completing the square, for which he provided geometric justifications.: 14  Because al-Khwarizmi was the first person to treat algebra as an independent discipline and introduced the methods of "reduction" and "balancing" (the transposition of subtracted terms to the other side of an equation, that is, the cancellation of like terms on opposite sides of the equation), he has been described as the father or founder of algebra. The English term algebra comes from the short-hand title of his aforementioned treatise (الجبر Al-Jabr, transl. "completion" or "rejoining"). His name gave rise to the English terms algorism and algorithm; the Spanish, Italian, and Portuguese terms algoritmo; and the Spanish term guarismo and Portuguese term algarismo, both meaning 'digit'. In the 12th century, Latin translations of al-Khwarizmi's textbook on Indian arithmetic (Algorithmo de Numero Indorum), which codified the various Indian numerals, introduced the decimal-based positional number system to the Western world. Likewise, Al-Jabr, translated into Latin by the English scholar Robert of Chester in 1145, was used until the 16th century as the principal mathematical textbook of European universities. Al-Khwarizmi revised Geography, the 2nd-century Greek-language treatise by the Roman polymath Claudius Ptolemy, listing the longitudes and latitudes of cities and localities.: 9  He further produced a set of astronomical tables and wrote about calendric works, as well as the astrolabe and the sundial. Al-Khwarizmi made important contributions to trigonometry, producing accurate sine and cosine tables and the first table of tangents.

2. Alī ibn Ahmad al-Nasawī (1010 - 1075)

With an HPI of 50.15, Alī ibn Ahmad al-Nasawī is the 2nd most famous Turkmen Mathematician.  His biography has been translated into 17 different languages.

Alī ibn Aḥmad al-Nasawī (c. 1011 possibly in Khurasan – c. 1075 in Baghdad) was a Persian mathematician from Khurasan, Iran. He flourished under the Buwayhid sultan Majd al-dowleh, who died in 1029-30AD, and under his successor. He wrote a book on arithmetic in Persian, and then Arabic, entitled the "Satisfying (or Convincing) on Hindu Calculation" (al-muqni fi-l-hisab al Hindi). He also wrote on Archimedes's Book of Lemmas and Menelaus's theorem (Kitab al-ishba, or "satiation"), where he made corrections to the Book of Lemmas as translated into Arabic by Thabit ibn Qurra and last revised by Nasir al-Din al-Tusi. Al-Nasawī's arithmetic explains the division of fractions and the extraction of square and cubic roots (square root of 57,342; cubic root of 3, 652, 296) almost in the modern manner. Al-Nasawī replaces sexagesimal by decimal fractions. Al-Nasawī criticises earlier authors, but in many cases incorrectly. His work was not original, and he sometimes writes of matters that he does not understand, e.g. "borrowing" in subtraction. Ragep and Kennedy also give an analysis of a mid-12th-century manuscript in which a summary of Euclid's Elements exists by al-Nasawī.
