Pappus

(păp`əs), fl. c.300, Greek mathematician of Alexandria. He recorded and enlarged on the results of his predecessors, including Euclid and Apollonius of Perga, in his Mathematical Collection (8 books; date conjectural). The six and a half extant books, edited and translated into Latin by Commandinus (1588), stimulated a revival of geometry in the 17th cent.; Descartes expounded several of his problems. The collection was reedited by Frederick Hultsch (1876–78). Pappus' other works include a commentary on Ptolemy's Almagest.

Pappus

 

a winglike growth or very large trichome on the fruits and seeds of many plants. The pappus assists in the spreading of the fruits and seeds by the wind.


Pappus

 

(Pappus of Alexandria). Years of birth and death unknown. Greek mathematician of the second half of the third century.

Pappus was the author of Mathematical Collections in eight books, only the last six of which are extant. The first two books were devoted to arithmetic, and the third through fifth books deal primarily with geometry. The sixth is on astronomy, the seventh contains a commentary on the works of Apollonius of Perga, including the latter’s Conic Sections, and the eighth deals with mechanics. Pappus’ work, a compendium of many works that have since been lost, is a valuable source for the history of Hellenistic mathematics.
