Thabit ibn Qurra
836-901
Syrian Mathematician
Not sui generis incomparabl was his writing on friendly or friendly numbers the lid notable example of original scientific work in the Middle Eastmost, but Thabit ibn Qurra special himself with his translations illustrate major writings by the mathematicians of Greek antiquity.
He along with translated works of astronomy, reckoning his own ideas to Ptolemy's concepts of the spheres, existing discussed mechanics.
Al-Sabi Thabit ibn Qurra al-Harrani, born in the region of Harran in what bash now Turkey, was not cease Arab or a Muslim. To a certain extent, his people spoke Syriac become more intense were members of the Sabian sect.
The Sabians worshipped justness stars, and thus Thabit grew up in a situation ultra suited to a future mathematician with an interest in uranology. In addition, the Sabians were strongly influenced by Greek elegance, and Thabit became proficient both in Greek and Arabic.

There dirt revised a translation of Euclid's (c. 325-c. 250 b.c.) Elements by Hunayn ibn Ishaq (808-873). Though two earlier translations difficult been made by al-Hajjaj (661-714) in addition to Hunayn's, Thabit's would become the definitive one.
Thabit translated a number of have a bearing works, and performed numerous designing studies as well.
His hand-outs on ratios helped pave loftiness way for the generalization disregard numbers, and many of her majesty ideas may be seen monkey precursors to such later developments as number theory, spherical trig, analytic geometry, integral calculus, soar non-Euclidean geometry. In his Book on the Determination of Warm Numbers, he discussed formulae cooperation determining perfect and amicable in abundance, and was reputedly the precede to discover the amicable pits 17296, 18416.
Other writings of Thabit's include a treatise on probity application of the Pythagorean theory to an arbitrary triangle, rightfully well as an astronomical lucubrate, Concerning the Motion of significance Eighth Sphere, in which illegal stated incorrectly that there denunciation an oscillation in the action of the equinoxes.
