Encyclopedia > Pappus of Alexandria

Pappus of Alexandria is one of the most important mathematicians of ancient Greek time, known for his work Synagoge or Collection (c. 340). Events Constantine II attacks his brother Constans near Aquileia, aiming for sole control of the western half of the Roman Empire. ...


He was born at Alexandria in Egypt. Although very little is known about his life, the written records suggest he was a teacher. Antiquity and modernity stand cheek-by-jowl in Egypts chief Mediterranean seaport For other uses, see Alexandria (disambiguation). ...


Synagoge, his best-known work, is a compendium of mathematics of which eight volumes survive. It covers a wide range of topics, including geometry, recreational mathematics, doubling the cube, polygons and polyhedra. Geometry (from the Greek words Geo = earth and metro = measure) is the branch of mathematics first popularized in ancient Greek culture by Thales (circa 624-547 BC) dealing with spatial relationships. ... Recreational mathematics includes many mathematical games, and can be extended to cover such areas as logic and other puzzles of deductive reasoning. ... Doubling the cube is one of the three most famous geometric problems unsolvable by straightedge and compass alone. ... Look up Polygon in Wiktionary, the free dictionary For other use please see Polygon (disambiguation) A polygon (literally many angle, see Wiktionary for the etymology) is a closed planar path composed of a finite number of sequential line segments. ... In mathematics, there are three related meanings of the term polyhedron: in the traditional meaning it is a 3-dimensional polytope, and in a newer meaning that exists alongside the older one it is a bounded or unbounded generalization of a polytope of any dimension. ...


In geometry, there are several theorems that are known by the generic name Pappus's Theorem, attributing them to Pappus of Alexandria. They include: Geometry (from the Greek words Geo = earth and metro = measure) is the branch of mathematics first popularized in ancient Greek culture by Thales (circa 624-547 BC) dealing with spatial relationships. ...

Pappuss centroid theorem consists of two related theorems dealing with the surface areas and volumes of surfaces and solids of revolution. ... WTF!?!? WTF!?!? WTF!?!? WTF!?!? WTF!?!? WTF!?!? WTF!?!? Pappuss hexagon theorem (attributed to Pappus of Alexandria) states that given one set of collinear points A, B, C, and another set of collinear points a, b, c, then the intersection points x, y, z of line pairs Ab and aB, Ac...

The American Thinker (2853 words)
Upon the death of Aristotle, the world was left with a number of “exoteric” writings, that is, published works, now lost, chiefly dialogues in Platonic form and perhaps content, and with his surviving followers, whose lectures on Aristotelian philosophy became the “esoteric” writings we now have, that is, writings unpublished in the lifetime of Aristotle.
Over the centuries, a series of editors attempted to establish a genuine canon of Aristotle, the center of their efforts shifted to Rome, the exoteric writings were lost, and the Aristotle we have today gradually emerged, which is based on Greek texts, not Arabic.
When Islam conquered most of the Christian lands of Asia and the Middle East and all of them on the north coast of Africa, including Egypt and with it Alexandria, part of the spoils of victory were small centers of Hellenistic scholarship, often Nestorian Christian, that continued for a while translating Greek philosophy into Syriac.
