Hypsicles hypsicles of alexandria. Born about 190 BC in Alexandria, Egypt Died about 120BC. hypsicles of alexandria wrote a treatise on regular polyhedra. http://www-groups.dcs.st-andrews.ac.uk/history/Mathematicians/Hypsicles.html
Extractions: Version for printing Hypsicles of Alexandria wrote a treatise on regular polyhedra. He is the author of what has been called Book XIV of Euclid 's Elements , a work which deals with inscribing regular solids in a sphere. What little is known of Hypsicles' life is related by him in the preface to the so-called Book XIV. He writes that Basilides of Tyre came to Alexandria and there he discussed mathematics with Hypsicles' father. Hypsicles relates that his father and Basilides studied a treatise by Apollonius on a dodecahedron and an icosahedron in the same sphere and decided that Apollonius 's treatment was not satisfactory. In the so-called Book XIV Hypsicles proves some results due to Apollonius . He had clearly studied Apollonius 's tract on inscribing a dodecahedron and an icosahedron in the same sphere and clearly had, as his father and Basilides before him, found it poorly presented and Hypsicles attempts to improve on Apollonius 's treatment.

Extractions: (ca. 310-230 BC) He was very knowledgeable in all sciences, especially astronomy and mathematics. He discovered an improved sundial, with a concave hemispherical circle. He was the first to formulate the Copernican hypotheses and is sometimes called the Ancient Copernican He countered the nonparallax objection by asserting that the stars to be so far distant that parallax was not measurable. Wrote On the Sizes and Distances of the Sun and Moon . In it he observed that when the moon is half full, the angle between the lines of sight to the sun and the moon is less than a right angle by 1/30 of a quadrant. From this he concluded that the distance from the earth to the sun is more than 18 but less than 20 times the distance from the earth to the moon. (Actual ). Without trigonometry he was aware of and used the fact that He also made other trigonometic estimates without trigonometry. ARCHIMEDES Apollonius of Perga (ca 262 BC - 190 BC) Apollonius was born in Perga in Pamphilia (now Turkey), but was possibly educated in Alexandria where he spent some time teaching. Very little is known of his life. He seems to have felt himself a rival of Archimedes. In any event he worked on similar problems. He was known as the ``great geometer" because of his work on conics.

Extractions: Definition: The evidence we now have for the development of the astrological system comes from relatively few ancient sources. We know - from references to them that have survived - that once there were many more, but these have now been lost.

In contrast, web pages of the opinions based on these original sources are legion...

Notes On The Logarithmic Spiral The socalled book XIV of Euclid s Elements, written by hypsicles of alexandriabetween 200 and 100 BC, contains some results concerning the section. http://www.spirasolaris.ca/rcarchibald.html
Extractions: The first discussions of this spiral occur in letters written by Descartes to Mersenne in 1638, and are based upon the consideration of a curve cutting radii vectores (drawn from a certain fixed point O ), under a constant angle, F Descartes made the very remarkable discovery that if B and C are two points on the curve its length from O to B is to the radius vector OB as the length of the curve from O to C is to OC whence s ap where s is the length measured along the curve from the pole to the point ( p, 01 , and a = sec F This leads to the polar equation (I) p = ke c F where k is a constant and c = cot a . The pole O is an asymptotic point. The pole and any two points on the spiral determine the curve; for the bisector of the angle made by the radii vectores is a mean proportional between radii. If c = 1 the ratio of two radii vectores corresponds to a number, and the angle between them to its logarithm; whence the name of the curve.
