Nasir Ad-Din Tusi

Top

Tusi Nasir ad-Din (b. Feb. 18, 1201, Tus, Khorasan--d. June 26, 1274, Baghdad), outstanding Persian philosopher, scientist, and mathematician.

Tusi became astrologer to the governor Nasir ad-Din 'Abd ar-Rahim. He made significant contributions to mathematics and astronomy; his Zij-i Ilkhani is a splendidly accurate table of planetary movements. His most famous and popular work is the Akhlaq Nasiri, resting upon the 11th-century Tahdhib al-akhlaq of Ibn Miskawayh, which he drafted while a prisoner of the Assassins and later revised for his Mongol master. This work has been translated into English. He made important contributions to many branches of Islamic learning and wrote in excellent philosophical prose.

Abu Ar-Rayhan Mohammad ibn Ahmad Al-Biruni 

Top

Al-Biruni,  in full ABU AR-RAYHAN MUHAMMAD IBN AHMAD AL-BIRUNI (b. September 973, Khwarezm, Khorasan--d. Dec. 13, 1048, Ghazna, Ghaznavid Afghanistan [now Ghazni, Afg.]), Persian scholar and scientist, one of the most learned men of his age and an outstanding intellectual figure.

Possessing a profound and original mind of encyclopaedic scope, al-Biruni was conversant with
Turkish, Persian, Sanskrit, Hebrew, and Syriac in addition to the Arabic in which he wrote. He
applied his talents in many fields of knowledge, excelling particularly in astronomy, mathematics,
chronology, physics, medicine, and history. He corresponded with the great philosopher Ibn Sina
(Avicenna). Some time after 1017 he went to India and made a comprehensive study of its culture.
Later he settled at Ghazna in Afghanistan.

Al-Biruni's most famous works are Athar al-baqiyah (Chronology of Ancient Nations); at-Tafhim ("Elements of Astrology"); al-Qanun al-Mas'udi ("The Mas'udi Canon"), a major work on astronomy, which he dedicated to Sultan Mas'ud of Ghazna; Ta'rikh al-Hind ("A History of
India"); and Kitab as-Saydalah, a treatise on drugs used in medicine. In his works on astronomy,
he discussed with approval the theory of the Earth's rotation on its axis and made accurate
calculations of latitude and longitude. In those on physics, he explained natural springs by the laws of hydrostatics and determined with remarkable accuracy the specific weight of 18 precious stones
and metals. In his works on geography, he advanced the daring view that the valley of the Indus had once been a sea basin. 

Omar Khayyam

Top

Omar Khayyam,  Arabic in full GHIYATH AD-DIN ABU AL-FATH 'UMAR IBN IBRAHIM
AL-KHAIYAMI AN-NISHABURI, Persian ABU OL-FATH 'OMAR EBN EBRAHIM
OL-KHAYYAMI (b. May 18, 1048, Nishapur, Iran--d. Dec. 4, 1131, Nishapur), Persian poet,
mathematician, and astronomer, renowned in his own country and time for his scientific
achievements but known to English-speaking readers for his roba'iyat ("quatrains") in the
version The Rubayat of Omar Khayyلm, published in 1859 by Edward FitzGerald (q.v.).

He later lived in Samarkand and Esfahan, and his brilliant work there continued many of the main lines of development in 19th-century mathematics. Not only did he discover a general method of extracting roots of arbitrary high degree, but his Algebra contains the first complete treatment of the solution of cubic equations. Omar did this by means of conic sections, but he declared his hope that his successors would succeed where he had failed in finding an algebraic formula for the roots.

Omar was also a part of an Islamic tradition, which included Thabit and Alhazen, of investigating
Euclid's parallel postulate. To this tradition Omar contributed the idea of a quadrilateral with
two congruent sides perpendicular to the base. The parallel postulate would be proved, Omar
recognized, if he could show that the remaining two angles were right angles. In this he failed, but his question about the quadrilateral became the standard way of discussing the parallel postulate.

That postulate, however, was only one of the questions on the foundations of mathematics that
interested Islamic scientists. Another was the definition of ratios. In fact, Omar argued that ratios should be regarded as "ideal numbers," and so he conceived of a much broader system of numbers than that used since Greek antiquity, that of the positive real numbers.

His name Khayyam ("Tentmaker") may have been derived from his father's trade. He received a
good education in the sciences and philosophy in his native Neyshabur (Nishapur) and in Balkh and
then went to Samarkand, where he completed an important treatise on algebra. He made such a
name for himself that he was invited by the Seljuq sultan Malik-Shah to undertake the astronomical observations necessary for the reform of the calendar. He was also commissioned to build an observatory in the city of Esfahan in collaboration with other astronomers. After the death of his patron in 1092, Omar went on a pilgrimage to Mecca. Returning to Neyshabur he taught and served the court from time to time by predicting events to come. Philosophy, jurisprudence, history,
mathematics, medicine, and astronomy are among the subjects mastered by this brilliant man.
Unfortunately, few of his prose writings survive; these include a few brief tracts on metaphysics and
a treatise on Euclid.

Abu Al-Qasim Khalaf ibn Abbas Az-Zahrawi (Albucasis)

Top

Abu al-Qasim, also spelled ABUL KASIM, in full ABU AL-QASIM KHALAF IBN 'ABBAS
AZ-ZAHRAWI, Latin ALBUCASIS (b. c. 936, near Cَrdoba [Spain]--d. c. 1013), Islam's
greatest medieval surgeon, whose comprehensive medical text, combining Middle Eastern and
Greco-Roman classical teachings, shaped European surgical procedures until the Renaissance.

Abu al-Qasim was court physician to the Spanish caliph 'Abd ar-Rahman III an-Nasir and wrote
At-Tasrif liman 'ajaz'an at-Ta`alif, or At-Tasrif ("The Method"), a medical work in 30 parts.
 The last chapter, with its drawings of more than 200 instruments, constitutes the first illustrated, independent work on surgery.

Although At-Tasrif was largely ignored by physicians of the eastern Caliphate, the surgical treatise
had tremendous influence in Christian Europe. Translated into Latin in the 12th century by the
scholar Gerard of Cremona, it stood for nearly 500 years as the leading textbook on surgery
in Europe, preferred for its concise lucidity even to the works of the classic Greek medical authority
Galen.

Ibn al-'Awwam

Top

An agriculturist who wrote the Arabic treatise on agriculture, Kitab al-fila- hah, the outstanding medieval work on the subject. The Spanish translation, published in the early 1800s, consists of 35 chapters dealing with agronomy, cattle and poultry raising, and beekeeping. It deals with 585 plants; explains the cultivation of more than 50 fruit trees; and includes many valuable observations on soils, manures, plant grafting, and plant diseases.
