Home Ancient Greek Scientists AGRICULTURALISTS ARCHITECTS ... PHYSICISTS GEOGRAPHER CONON OF SAMOS (fl. 3rd century BC) Life Conon lived mostly in Alexandria, where he was court astronomer to Ptolemy III Euergetes. He succeeded Euclid at the Alexandrian School. Although he is chiefly known as an astronomer and astro-meteorologist, he also worked on many mathematical problems with Archimedes, who had been a student of his. He is cited by Apollonius of Perga and Pappus. He discovered the Spiral of Archimedes, a curve that was used extensively by Archimedes in some of his mathematical investigations. Conon discovered the constellation which he called Coma Berenices ("Berenice's Hair"), thus immortalising Ptolemy's wife, Queen Berenice, and her luxuriant tresses. Callimachus wrote a poem under this title, which was translated into Latin by Catullus. Work Conon's principal writings are: "On astronomy": 7 books. Dedicated to Ptolemy III Euergetes. Contained among other matters some of his own observations on eclipses. Hipparchus based his work on these books. Lost. "Parapegma": Calendar of meteorological forecasts and of the risings and settings of the stars. Based on observations made in Italy and Sicily at the time of Ptolemy. (It was then that he made the acquaintance of Archimedes.) Lost.

In ancient times, Samos, although small, played a really significant role in culture and politics not only for the region of Ionia, but for the entire ancient Greece. From the evidence that has been found, derives that human beings have lived on Samos since the 3rd millenium BC, if not earlier. Its favourable position at the sea crossroad that link central Greece with East played a significant role for its development. Several megatheriums and other rare species of the prehistorical era lived on this island. Bones that found the previous century decorate the show -cases of the paleontological museums of USA and Europe. Some of these paleontological findings are in the museum of Mytilinion of Samos. Bones from the Paleontological Museum of Mytilinion Samos Traces of the human race have been found at the Hill of Castro from the late Neolithic era (fourth millennium B.C.). The first inhabitants belong to the Pelasgic tribes that spread the worship of Hera. According to mythology, Hera was born at the banks of the rive Imvras and was considered as the protector of Samos. Thus, her sacred bird, the peacock, often appeared on currency and escutcheons of the hegemony of Samos later.

11. History Of Alexandria: The Ptolemaic Legacy In the Mouseion, the first studies of conic sections (Ellipse, Parabola, andHyperbola) were carried out by conon of samos and Appolonius of Perga. http://ce.eng.usf.edu/pharos/Alexandria/History/legacy.html

The Ptolemaic Legacy The Mouseion / Library When Ptolemy Soter assumed power, he asked Demitrius Phalerus , a follower of Aristotle , to found a library system at Alexandria that would rival that of Athens. The Alexandrian Mouseion , however, far superseded its Greek prototype to become an intellectual and scientific institution; a university system rather than a bibliotheca. It was here, in the third century BC, that Archimedes invented the pump still in use today and known as Archimedes' screw , and, in the second century BC, that Hypsicles first divided the circle of the zodiac into 360 degrees. Ancient historians claim that the library's 500,000 book collection was so comprehensive that no manuscript was available in any library worldwide that was not available in Alexandria. Mathematics Have you ever heard of Euclidean Geometry? Did you know that Euclid lived, developed his theories, and wrote Elements at the Alexandria Mouseion during the reign of Ptolemy II Philadelphus? In his Elements , Euclid provided a comprehensive analysis of geometry, proportions, and theory of numbers. His other notable contribution

12. Archimedes, Of Syracuse It is probably here that he met conon of samos, who he remained in correspondencewith as a personal as well as professional friend. http://www.nahste.ac.uk/isaar/GB_0237_NAHSTE_P1090.html

Archimedes, of Syracuse Biographical Information Occupation, Sphere of Activity Archimedes of Syracuse ( c287-212 BC ) was a mathematician and inventor. His father was Pheidias, an astronomer, of which we know nothing. While he is famous now, as he was then, largely because of his inventions, it is reported that he despised invention as being less "pure" than geometry, and he never wrote about his creations. Little is known about his life, though he is described by some as having been a relative - by others as a close friend - of Hiero (or Hieron) II, King of Syracuse, who employed him as a tutor to his son. He almost certainly spent a part of his life studying in Alexandria - where he is thought to have played an important role in the development of Euclidian mathematics. It is probably here that he met Conon of Samos, who he remained in correspondence with as a personal as well as professional friend. He wrote a number of books, ten of which have survived largely intact. These deal mostly with geometrical problems - particularly centres of gravity of solids, studies of spheres and conical sections, spirals and other mathematical matters. Among his propositions, particularly interestingly, are an approximation of 'pi' - which he reached after circumscribing and inscribing a circle with two 96-sided polygons, an explanation of the law of levers, a foundation for theoretical mechanics, a means of accurately approximating square roots of large numbers, a precursor to Newton and Leibniz's calculus and a proposed system of numbering for large figures which went high enough - 8x10^16 in modern notation - to count to a higher number than the number of grains of sand that would fill the universe - or so Archimedes believed.

13. Apollonius Of Perga | 262-190 BC | Greek Mathematician He credited conon of samos (c280c220 BC), a collaborator of Archimedes of Syracuse(c287-212 BC), and Euclid of Alexandria (c325-c265 BC) with the original http://www.nahste.ac.uk/isaar/GB_0237_NAHSTE_P1095.html

Biographical Information Occupation, Sphere of Activity Apollonius of Perga ( c262-c190 BC ) - whose life story remains a mystery as it is not even certain he was born in Perga, and his life dates are rough estimates - is remembered for his only major work still extant, Conics , an 8-book work (of which the first 7 survive) which summarises the knowledge of the time on the subject, and goes on to introduce numerous major new ideas. The terms "ellipse", "parabola" and "hyperbola" to describe conical sections, were coined in this work, and new definitions of the shapes were found. Until then, they had been defined as sections, perpendicular to the base, of different types of cone. Apollonius redefined them all as sections, at different angles, of the same cone. He credited Conon of Samos ( c280-c220 BC ), a collaborator of Archimedes of Syracuse ( c287-212 BC ), and Euclid of Alexandria ( c325-c265 BC ) with the original work on conical sections that inspired this work. Of his other books, all, with the exception of

She was the wife of Ptolemy III and the daughter of Magas of Cyrene. When King Ptolemy III went to war against Seleucos, the king of Syria, Berenice promised her hair to Aphrodite, the Greek goddess of love and beauty, if her husband returned safely and victorious. After the king's return, Berenice, condemned by her wish, cut her hair though loss was hard. The next day, when the king went to have a look at his wife's hair, he was furious to find that the hair had be stolen. But at nightfall, Conon of Samos showed the king the new constellation in the sky. The astrologers said that the goddess Aphrodite had placed her tresses among the stars and King Ptolemy III was satisfied. III - Stars and object in Coma Berenice

Fried, as a companion volume to our edition of Conics Books I-III. Conics IV deals with the way pairs of conic sections can intersect or touch each other. In his Introduction to the translation, Fried shows that this book has been misappraised by scholars too much inclined to see Apollonius's work merely as a precursor to the analytic geometry of the seventeenth century. He writes, "Playfulness is one of the real delights of Book IV. One can see in this playfulness the artful way Apollonius contends with the main challenge of the book-the problem of how the opposite sections, specifically, meet other sections of a cone and other opposite sections- how he gives this problem both foundation and context." 7 x 10", 104 pages.

Coma Berenices Berenices Hair Greek Alphabet The main star in Coma Berenice Star R A Decl 1950 Lat Mag Sp gamma beta Diadem alpha Myth and history: Coma Berenice, Berenice's Hair, is a constellation that consists of a multitude of stars, several clusters, nebulae and galaxies. The best known and most famous galaxy is M88. The naked eye can really see a wealth of glitter in the area of Coma Berenices, but a small telescope reveals an even more glorious display of astral abundance. [NPS p.150]. Coma Berenice seems to have been first alluded to by Eratosthenes as Arladne's Hair in his description of Ariadne's Crown. It was not known until about 243 BC, in the reign of the 3rd (Euergetes), the brother and husband of Berenice, whose amber hair we now see in the sky figure. It was the happy invention of this constellation by Conon of Samos, the royal astrologer, that consoled the royal pair after the theft of the tresses from the temple of Arsinoe Aphrodite at Zephyrium. For nearly the next 2000 years its right to a place among the constellations was unsettled, some referred to it as the stars behind the Lion's tail, or connected with Virgo, or an asterism in itself. Tycho, in 1602, set the question at rest by cataloguing it separately, adopting the early title as we have now. Some versions of the story turned the lady's hair into a hair-star or comet. [SLM p.168]. Aratos referred to it as 'Victory Bearing' and said 'the consecrated spoils of Berenice's yellow head, which the divine Venus placed, a new constellation, among the ancient ones, preceding the slow Bootes'. Hyginus and Ptolemy referred it as a cloudy condensation, it was called Al Utha (Arab?), literally 'a Mixture'. It was also called by the Greek words Tricas, Tericas and Triquetras which means 'tresses'. [SLM].
