Extractions: Timeline related to Greek Astronomy About 600 BC Pherekydes, the teacher of Pythagoras , performed astronomical measurements with a heliotropion device in the island of Syros. (Herodotus describes later that the Greeks learned to use the Gnomon and Polos from the Egyptians and also the division of the day in 12 parts.) About 585 BC Thales of Miletus (636-546) BC predicts a solar eclipse. About 530 BC Pythagoras gives the name cosmos to the universe. About 520 BC Anaximander proposes that the Earth surface is cylindrical About 500 BC Heraclitus of Ephesus says the Universe is 10800 years old. In 1766 Georges Buffon said that the Earth is older than 6000 years (from fossils). About 470 BC Parmenides says that the Earth shape is spherical Harpalus, Astronomer (?-460) BC About 450 BC Anaxagoras of Athens (500-428) BC taught that the moon shines with the light of the Sun (a hot red stone larger than Peloponese) and so was able to explain the eclipses. Oenopides (500-432) BC measured the inclination of the Earth axis with respect to the ecliptic plane to be 24 degrees, defined the Great Year to be about 59 years, the interval with an exact repetition of days in a year and the lunar cycle with the Sun and Moon in the exact same locations in the sky, accounting not just for months but also its inclination. 450-385 BC Philolaus of Croton, in southern Italy, (c. 470 - c. 385) BC was the precursor of Copernicus in moving the earth from the center of the cosmos and making it a planet, but in Philolaus' system it does not orbit the sun but rather the central fire. Some scholars regard the astronomical system as a significant attempt to try to explain the phenomena, but others see it as primarily of mythic and religious significance. Philolaus is the first to incorporate all five planets commonly known in antiquity into an astronomical scheme in the correct order, which indicates that he was aware of the most up-to-date astronomical data.

II - Legend The constellation were named by the royal Greek astrologer Conon of Samos (247 BC) after the hair of Egyptian Queen Berenice. 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
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
Extractions: 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.

Extractions: 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

Extractions: Archimedes was born 287 BC in Syracuse, Sicily. Archimedes was a famous mathematician whose theorems and philosophies became world known. He gained a reputation in his own time which few other mathematicians of this period achieved. He is considered by most historians of mathematics as one of the greatest mathematicians of all time. He discovered pi. Most of the facts about his life come from a biography about the Roman soldier Marcellus written by the Roman biographer Plutarch. He was best known for his discovery of the relation between the surface and volume of a sphere and its circumscribing cylinder, for his formulation of a hydrostatic principle Archimedes' principle and for inventing the Archimedes screw (a device for raising water). Archimedes Principal states: an object immersed in a fluid experiences a buoyant force that is equal in magnitude to the force of gravity on the displaced fluid. He also invented things such as the hydraulic screw - for raising water from a lower to a higher level, catapult, the lever, the compound pulley and the burning mirror. In mechanics Archimedes discovered fundamental theorems concerning the centre of gravity of plane figures and solids.

Extractions: These daring words were made by a man whose genius changed the worlds of science and math forever. Many historians consider Archimedes to be one of the greatest scientists in history and the greatest mathematician of all time. Archimedes' contributions to science and math include the discovery and development of the laws and principles of mechanics, buoyancy, hydrostatics, specific gravity, the lever, and the pulley; in addition, he discovered how to find the measurement of a circle and the volume of a solid. These discoveries and other inventions were the life and love of Archimedes. Archimedes grew up in the Greek city-state of Syracuse on the island of Sicily. His father was an astronomer named Phidias. Archimedes is known to be a relative of Hiero II, who was the king of Syracuse during Archimedes' life. Hiero and Archimedes were very close friends. However, nothing else is known about any other members of Archimedes' family. Archimedes lived in Syracuse for his whole life, except for when he went to school in Alexandria, and at one point it was up to Archimedes' inventions to save Syracuse from being taken by the Romans. Archimedes had a good education as a boy, for the Greeks loved knowledge and sent their sons to schools to become knowledgeable Greek citizens. Some of the subjects that he studied as a boy were poetry, politics, astronomy, mathematics, music, art, and military tactics. When Archimedes was in his teens he sailed to Egypt to study in Alexandria. There he went to a famous school of mathematics that had been founded by Euclid. Archimedes studied astronomy, physics, and mathematics with many other great minds of the time. His teacher was named Conon of Samos. Conon was one of the greatest influences that Archimedes had in his life. He taught Archimedes many things about life and science. Archimedes' studies in Alexandria became the foundation on which he built his career as a scientist and mathematician.

Extractions: 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].

Extractions: 9 April The constellation Coma Berenices refers to a classical story concerning the hair of Berenice, the wife of Ptolemy III of Egypt. While the story is an old one, the constellation is relatively new, being introduced by Tycho Brahe (1546-1601). The stars that form the constellation really aren't that remarkable to look at, only a handful of fourth-magnitude stars, including three Bayer stars . Yet there are several fine binaries, eight Messier objects and the Coma Star cluster, not included in Messier's list.

Extractions: Nearly overhead at around midnight, local daylight time, is the constellation that owes its name to a theft: Coma Berenices or Berenices Hair. Eratosthenes in the 3rd century BC was among the first to make note of this faint group of stars. It is actually a large, loose galactic star cluster some 250 light years away that appears as a faint shimmering patch of light on clear moonless nights. As a cluster, Coma Berenices is by far at its best in a pair of good binoculars. If, on the other hand, you attempt observation of it with a high-powered telescope the impression of a cluster will become totally lost because of the telescopes narrower field of view. The queen wigged out While virtually all of the constellations are named for mythological people, beasts and inanimate objects, Coma Berenices is actually associated with a real person. Berenice II was an Egyptian Queen, the wife of Ptolemy Euergenes (also known as Ptolemy III), the king of Egypt, who reigned around 250 BC.

The Equiangular Spiral Spira Mirabilis Building upon the work of conon of samos, Archimedes of Syracuse wrote adefinitive early work on the subject in 250 BC entitled On Spirals. http://online.redwoods.cc.ca.us/instruct/darnold/CalcProj/Sp98/GabeP/Spiral.htm
Extractions: Gabriel Peterson The Equiangular Spiral: Spira Mirabilis Gabriel Peterson Math 50C: Multivariable Calculus Abstract The purpose of this article is to develop the parametric equation for the plane curve of the equiangular spiral also known as the logarithmic spiral or the logistique from its geometric definition. Through analysis, it was found to be where a is an arbitrary constant and a is a constant angle made between the radial vector to any point on the curve and the tangent line at that point. Introduction Most readers will have had at least some informal introduction to the elegant beauty of the spiral prior to reading this. Certainly, most will have witnessed the sublime geometry of a spiral in the vortex of water rushing down a drain, the tempest of a hurricane, the hypnotic pattern of a magicians spiral, the shape of a snails shell, the inscrutable movement of the arms of a spiral galaxy like our own... The formal mathematical study of spirals as did so many other rich intellectual traditions present today began with the ancient Greeks. Building upon the work of Conon of Samos, Archimedes of Syracuse wrote a definitive early work on the subject in 250 BC entitled On Spirals.
