Hypatia of Alexandria was the first woman to become famous for her studies in mathematics, philosophy, and science. Unfortunately, none of her work has survived. Her life's history is known only through documents and letters from the time in which she lived. Letters from one of Hypatia's students tell us much about her talent. Hypatia was born in Alexandria, Egypt in about A.D. 370 . At the time, Alexandria was an important place of learning. Nothing is really known about Hypatia's mother. Her father was a famous philosopher, or thinker, named Theon of Alexandria. Theon taught at the Museum in Alexandria. The Museum was somewhat like a college. Historians believe that Hypatia learned mathematics and science from her father. She also learned other things from him. In the morning she exercised according to the routine her father designed for her. In the afternoon he taught her how to use words to influence people. Together, father and daughter wrote books on the ideas of other important mathematicians and astronomers . The books helped make the ideas easier to understand. They also allowed people who lived years later to keep studying the teachings of these thinkers. Alexandria, Egypt

43. Euclid Of Alexandria One of the more important editions was by theon of alexandria in 4th century AD,in which he admits to adding the second part of VI. 33. http://www.math.sfu.ca/histmath/Europe/Euclid300BC/EUCLIDMAIN.HTML

Euclid of Alexandria c. 300 B.C.E. "Ptolemy once asked Euclid whether there was any shorter way to a knowledge of geometry than by a study of the Elements, whereupon Euclid answered that there was no royal road to geometry." Proclus Diadochus Euclid of Alexandria, author of the most successful mathematics textbook ever written and with the exception of Autolycusí Sphere , is author of the oldest Greek mathematical treatise extant. More than half of Euclidís works have been completely lost, others surviving the ages only through translations and interpretations. Little is known about his life, yet his name and writings have managed to continue being a major influence on geometry for two millennia. Much of what is believed to be known about Euclid comes from Proclusí Eudemian Summary . Proclus states that he was a contemporary of King Ptolemy I Soter. (305 - 285 B.C.E.) Some students of his work have asserted that he was in fact, a disciple of the Platonic school and had studied with students of Plato , possibly in Athens at the Academy. Euclid was older than Archimedes (287 - 212 B.C.E.) and Eratosthenes and younger than

Hypatia A great scientist, learned in mathematics, astronomy, and philosophy. A woman who should be the role model of modern "feminists," or anyone male or female who admires those qualities which separate humanity from the brute beasts and give meaning and dignity to our lives. Instead, we see so many of America's young women playing the role of hem kissers to the likes of such culture-annihilating trash as Betty Friedan, Bela Abzug, Gloria Steinhan, and Hillary Clinton. What a shame! An exceptional Ellinitha When women in the rest of the world were thought to be of lesser value than the family cow, Greece was producing prominent women in fields of endeavor strictly monopolized by men in other lands a situation that is an almost international phenomenon even today One of these exceptional women was a scholar and scientist who excelled as a mathematician, astronomer, and philosopher. Her name was Hypatia, and she was born circa 355 A.D. in the Greek city of Alexandria, in today's Egypt. She was the daughter of the mathematician and philosopher Theon of Alexandria, who as

47. PAPPUS OF ALEXANDRIA - LoveToKnow Article On PAPPUS OF ALEXANDRIA Suidas states that he was of the same age as theon of alexandria, who wrotecommentaries on Ptolemys great work, the Syntaxis mathematica, and flourished in http://18.1911encyclopedia.org/P/PA/PAPPUS_OF_ALEXANDRIA.htm

PAPPUS OF ALEXANDRIA PAPPUS OF ALEXANDRIA We can only conjecture that the lost book i., as well as book ii., was concerned with arithmetic, book iii. being clearly introduced as beginning a new subject. The whole of book ii. (the former part of which is lost, the existing fragment beginning in the middle of the 14th proposition) related to a system of multiplication due to Apollonius of Perga. On this subject see Nesselmann, Algebra der Griechen (Berlin, 1842), pp. 125134; and M. Cantor, Gesch. d. Math. i.~ 331. In book v., after an interesting preface concerning regular polygons, and containing remarks upon the hexagonal form of the cells of honeycombs, Pappus addresses himself to the comparison of the areas of different plane figures which have all the same perimeter (following Zenodoruss treatise on this subject), and of the volumes of different solid figures which have all the same superficial area, and, lastly, a comparison of the five regular solids of Plato. Incidentally Pappus describes the thirteen other polyhedra bounded by equilateral and equiangular but not similar polygons, discovered by Archimedes, and finds, by a method recalling that of Archimedes, the surface and volume of a sphere. According to the preface, book vi. is intended to resolve difficulties occurring in the so-called ~iucpi3c ?wrpoPo/Ao(lpsvol. It accordingly comments on the Sphaerica of Theodosius, the Moving Sphere of Autolycus, Theodosiuss book on Day and Night, the treatise of Aristarchus On the Size and Distances of the Sun and Moon, and Euclids Optics and Phaenomena.

Hypatia and Mathematics Hypatia of Alexandria is well known for her mathematics, as she is the first known woman to be significantly involved in the field. It is not known whether Hypatia wrote her own books or text on the subject of math, but it is known that she made commentaries. Four works attributed to her are Apollonius's Conics , Diophantus's Arithmetica , Ptolemy's Almagest , and Euclid's Elements . She reportedly worked on these commentaries with her father, Theon of Alexandria, a well-known mathematician and philosopher. Appollonius of Perga is well known for his contributions to the ideas of conics. Conics, in mathematics, is the concept of the slicing of a cone at certain places to produce closed or open curves. Closed curves are the circle and the ellipse;t open curves are the parabola and hyperbola. Apollonius is noted for giving the ellipse, parabola, and hyperbola their names in his work, Conics Conics survives in four books in Greek, three books in Arabic, and one book is lost. Although Hypatia is not noted as a commentator of Conics , some believe to see "traces of Hypatia’s hand" in the work. Further evidence of her involvement in the text is found in the

Hypatia , the daughter of Theon of Alexandria, was born in about 370 AD. she is the earliest woman scientist whose works have been documented. As a young woman, she traveled to Athens and Italy. Upon her return to Alexandria, she became a philosopher and mathematician. She was appointed to expound the doctrines of Plato and Aristotle and was a noted lecturer on the subjects of mathematics, astronomy, philosophy, and mechanics. Most of her writings dealt with mathematics, especially algebra. Her most noted work, called Arithmetica, was a commentary on the writings of Diophantus. Hypatia also wrote an explanation of the geometry works of Apollonius of Perga, which was titled, On the Conics of Apollonius. Later in her career she worked with Theon and coauthored a work on Euclid's geometry which is titled Elements. In addition to her mathematical works, Hypatia also developed an apparatus for distilling water, an instrument for measuring the level of water, a plane astrolabe (for measuring the positions of the stars, planets, and sun) and a graduated brass hydrometer for determining the specific gravity of a liquid. Hypatia's philosophical beliefs were in conflict with the views of the Christian rulers of the city of Alexandria. When Cyril, a fanatical Christian, became Partiarch of Alexadria in 412 AD he began a persecution of scholars in the city. In 415 AD Hypatia was arrested, tortured and killed in the church called Caesarium. References Alic, M. (1986).

Hypatia's work on Ptolemy's Almagest References Theon of Alexandria's commentary on the third (book) of the Mathematical syntaxis of Ptolemy, "the edition having been prepared [paranagnostheisa] by the philosopher, my daughter Hypatia." From The Primary Souces for the Life and Work of Hypatia of Alexandria, by Michael A.B. Deakin Theon was Hypatia's father and he devoted much of his professional life to the production of student editions or "commentaries" on earlier mathematical classics, notably the works of Euclid and Ptolemy. The translation of the brief sentence at the start of Book III of his Commentary on Ptolemy's major work is the subject of much debate. It is seen by some (Rome, Heath, Knorr) as attributing authorship of the material to Hypatia and most likely indicating that a computational advance (an improved technique for long division) was devised by Hypatia.

Revisions Worksheet Hypatia of Alexandria (355 or 370 - 415) philosopher, astronomer and mathematician I chose this historical figure for three reasons. Obviously my main intent was to locate women in the ancient world who left their mark on the Western Intellectual Tradition despite their sex; but then as I got into her story, I discovered that she had been brutally murdered by fanatical monks because she was a “pagan” (i.e., a non-christian) and a scientist, and as such a threat to the church. Hypatia [hi-pay'-she-ah] of Alexandria is certainly not a household name in your world; but in Egypt, the center of Greek culture in the Fifth Century, she was a phenomenon of note. Hypatia's father, Theon of Alexandria, was a teacher of mathematics with the Museum of Alexandria in Egypt. A center of Greek intellectual and cultural life, the Museum included many independent schools and the great library of Alexandria. Hypatia studied with her father, and with many others including Plutarch the Younger. She herself taught at the Neoplatonist school of philosophy. She became the salaried director of this school in 400. She probably wrote on mathematics, astronomy and philosophy, including about the motions of the planets, about number theory and about conic sections. She corresponded with and hosted scholars from others cities. Synesius, Bishop of Ptolemais, was one of her correspondents and he visited her frequently. Hypatia was a popular lecturer, drawing students from many parts of the empire.

Bibliography Introduction This web page provides a set of JavaScript calendar and ephemeris modules for calculating geocentric luni-solar and planetary positions for an arbitrary calendar date and time according to the kinematical models of the Sun, the Moon and the planets described in the Almagest (also known as the Mathematike Syntaxis ) of Claudius Ptolemy ( c . 150 AD). The mean motions of the Sun, the Moon and the planets adopted in these modules correspond exactly with Ptolemy’s mean motion tables and the corrections for their eccentric and epicyclic motions are accurately modelled according to the luni-solar and planetary models discussed by Ptolemy in his Almagest As Ptolemy s tables were probably used most often for astrological rather than for astronomical computations, a table displaying the astrological aspects between the luminaries (and the lunar ascending node) with some other astrological quantities is also provided. At present, latitudes are given only for the Sun (this is always zero) and the Moon. In the near future, latitudes and distances will also be supplied for the other luminaries.

Ptolemy's Astronomical Works (other than the Almagest Canobic Inscription The text known as the Canobic Inscription is a transcription made in late antiquity of a lost public inscription that Ptolemy erected in A.D. 149/150 at Canopus in Egypt. The inscription records the numerical parameters of Ptolemy's models for the motions of the sun, moon, and planets. Most of the data in the Canobic Inscription agree with the Almagest , but there are a few significant differences which are now recognized as proving that the Almagest was completed later than the inscription.
