Person: AlMahani, Abu Abd Allah Muhammad ibn Isa
AlMahani was an Islamic mathematician who tried to solve some of Archimedes' problems on cutting up spheres.
Mathematical Profile (Excerpt):
 We do know a little about alMahani's work in astronomy from Ibn Yunus's astronomical handbook alZij alHakimi alkabir.
 In this work Ibn Yunus quotes from writings by alMahani, which have since been lost, which describe observations which alMahani made between the years 853 and 866.
 At least we have accurate dating of alMahani's life from this source.
 It gives a full account of the Arabic literature which was available in the 10th century and in particular mentions alMahani, not for his work in astronomy, but rather for his work in geometry and arithmetic.
 However the work which alMahani did in mathematics may well have been motivated by various problems of an astronomical nature.
 We know that some of alMahani's work in algebra was motivated by trying to solve problems due to Archimedes.
 It was Omar Khayyam, giving an important historical description of algebra, who puts alMahani's work into context.
 It would be too easy to say that since alMahani has proposed a method of solution which he could not carry through then his work was of little value.
 However, this, as Omar Khayyam is well aware, is not so at all and the fact that alMahani conceived the idea of reducing problems such as duplicating the cube to problems in algebra was an important step forward.
 A number of works by alMahani have survived, in particular commentaries which he wrote on parts of Euclid's Elements.
Born about 820, Mahan, Kerman, Persia (now Iran). Died 880, Baghdad, Iraq.
