Atzema: "[HM] Apollonius' Conics" On August 31, 1999, Eisso Atzema asked, about Apollonius: It does not seems to be a tradition, since contrarily to Heath (as quoted by Eisso), Paul Ver Eecke writes (in "Les Coniques d'Apollonius de Perge", p. XVIII-XIX, my poor translation, "off the bat"): The fourth book contains fifty-seven propositions. The first twenty-three, demonstrated by the method of reductio ab absurdo, are not else, in fact, than the reciprocal of third book's propositions XXX to XL, and we shall mention only the IXth, which gives a means to draw from one point two tangents to a conic. The thirty-four other propositions all concern the exact number of encountings between the conic sections and the circle's circumference. These last propositions were not new; indeed Apollonius tells them had been already exposed by Conon of Samos: that their demonstrations had been criticised by the geometer Nicoteles, and that Nicoteles himself

Maybe in reply to: Phill Schultz: "[HM] Earliest priority dispute?" John W. Dawson, jr. wrote: In the prefatory letter to Book I of the CONICA, Apollonius says that "The third book contains many incredible theorems of use for the construction of solid loci and for limits of possibility (tous diorismous) of which the greatest part and the most beautiful are new (xsena). And when we had grasped these, we knew that the three-line and four-line locus had not been constructed by Euclid, but only a chance part of it and that not felicitously. For it was not possible for this construction to be completed without the additional things found by us." About this, Pappus says "[Apollonius] was able to add the missing part to the locus because he had Euclid's writings on the locus already before him in his mind, and he had studied for a long time in Alexandria

The Library of Alexandria by Ti. Dionysius Draco The Founding of the Museum and the Library The Museum was founded by Demetrius Phalerus, under the patronage of Ptolemy I, Ptolemy Soter. The establishment of the Library was handed down to Ptolemy II, Ptolemy Philadelphus, in 283 B.C., and it was during his reign that the monarch began the practice of attracting scholars, housing and funding them in the Museum, and collecting the vast Library. The idea of a formal institution for scholars of all kinds, complete with a library, was a new one, and the Museum was modelled on the Lyceum of Aristotle in Athens; Demetrius himself, an exiled tyrant of Athens, was one of Aristotle's followers. A second "daughter" library, the Serapeion, was soon established in the temple of Serapis, a popular god invented by the Ptolemies as a synthesis of Zeus, Pluto, Osiris, and the Apis bull. This library, found in the Rhakotis or Egyptian sector, was open to all, not just to royally pensioned scholars, and had copies of many of the Museum's scrolls. The Function of the Museum and the Library The Museum was a shrine built for the glorification of the Muses, and from the outset contained lecture halls, laboratories, observatories, living quarters, colonnades for ambulatory discussions, a dining hall, a garden, a zoo, the shrine itself, and, presumably, the Library, which most archaeologists and scholars conclude was housed within the shrine and not in a separate building. An estimated 30-50 scholars were probably permanently housed there, probably fed and funded first by the royal family, and later, according to an early Roman papyrus, by public money. The administrator of the Museum was a priest, appointed by the Pharaoh and was ,together with a separate Librarian, responsible for the whole collection.

Mathematician Report Index Below is a list of mathematicians. You may choose from this list or report on a mathematician not listed here. In either case, you must discuss with me the mathematician you have chosen prior to starting your report. No two students may write a report on the same mathematician. I would advise you to go to the library before choosing your topic as there might not be much information on the mathematician you have chosen. Also, you should determine the topic early in the term so that you can "lock-in" your report topic!! The report must include: 1. The name of the mathematician. 2. The years the mathematician was alive. 3. A biography. 4. The mathematician's major contribution(s) to mathematics and an explanation of the importance. 5. A historical perspective during the time the mathematician was alive. Some suggestions on the historical perspective might be: (a) Any wars etc. (b) Scientific breakthroughs of the time (c) Major discoveries of the time (d) How did this mathematician change history etc.

Slip into a Coma If you find yourself this week enjoying spring's planetary alignment in the early evening's western skies, I have a suggestion: While you're at it, slip into a coma. One of the least appreciated constellations but one of great interest to astronomers is Coma Berenices, located next to well-known Leo the Lion. About nine o'clock tonight face south and look almost directly up. You'll see something that looks like a backwards question mark. That is the head and mane of a regal Leo the Lion stalking bright Jupiter as it leads him into the horizon. A little to the east (left) of Leo's head is the rest of the lion's body which includes the very bright Denebola. Denebola marks the Lion's loin - his hindquarters. If the night is clear and moonless you'll see a dim cluster of stars almost as far up and to the left of Denebola as Leo's head is up and to the right. This is the Coma Berenices Star Cluster, which when seen through a binoculars consists of thirty to forty faint stars. But how did it get there? That depends on whose story you believe.

Our Founder B Y H. T. C ROFT A RCHIMEDES of Syracuse was the son of Pheidias the astronomer, and on intimate terms with, if not related to, King Hieron and his son Gelon. He spent some of his life in Alexandria, and was friendly with Conon of Samos and Eratosthenes; then returned to Syracuse for a life devoted to mathematical research. He perished in 212 B C . (at age 75, according to Tzetzes) in the sack of Syracuse. Stories of other details of his life, culled from many sources, are somewhat dubious. No authenticated picture remains, in spite of three (totally different) purported portraitures in classical works of the last century. The only contemporary biography is not extant. Tales of his preoccupied abstraction - drawing diagrams in ashes, or in oil when anointing himself, and forgetfulness of food - remind us irresistibly of Newton's going out in a fit of absentmindedness without his trousers. He died as he had lived, deep in mathematical contemplation. Several authors give variously garbled accounts, the most picturesque being that, though Marcellus the Roman commander wished him to be spared, a common soldier, enraged by the great man's request to "Stand away, fellow, from my diagram," dispatched him. As he had asked, his discovery of the surfaces of the sphere and cylinder was depicted on his tombstone, which was later found in a dilapidated state and restored by Cicero when quaestor in Sicily. When Hieron asked for a practical demonstration of a great weight moved by a small force, in connection with his famous utterance "
