The most famous onethe mathematician, seemingly born on the Greek island of Samos, lived between circa 580 and 500 BCE. During a short journey to Egypt, when being a young man of 22, Thales (the reknown Greek philosopher) suggested him to study in Egypt to enlarge his knowledge. On his return to Greece, he prepared himself to travel to Tyre in Lebanon, apparently because of a commercial connection of his father. There, he was initiated for the first time into the Ancient Mysteries of the Phoenicians and studied for about 3 years in the temples of Tyre, Sidon, and Byblos. From there, he navigated to Egypt, the source of the Ancient Mysteries . On the road, he lingered for a while in the gulf of Haifa at a temple on Mount Carmel, Israel (after the destruction of the First Hebrew Temple of Jerusalem). In Egypt, he was initiated and studied for about 22 years. Apparently, he studied for another 13 years in Babylon as well, while he was captured on his way back from Egypt to Greece. In fact, the Ancient Mysteries'

This is the quadratic formula, as it is taught to most of us in school: x -b a a b ac gives the solution to a generic quadratic equation of the form: ax bx c The development, or derivation, of a mathematical idea is usually as logical, deducible and rectilinear as possible. This brings about the common notion that its historical development is similarly as continuous, logical and rectilinear: one mathematician picking up an idea where another mathematician left it. Using the quadratic formula as an example, it will be shown that the historical development of mathematics is not at all rectilinear. Instead, parallel developments, interconnections and confluences can be found, which - to complicate this stuff even further - are also interrelated with social, cultural, political and religious matters. The so-called quadratic formula has been derived in the course of a few millennia to its current form, which is taught to most of us in school. This Entry will strictly concentrate on the historical development of the quadratic formula. Some mathematical background may be of use to fully understand the described development, however the maths used in this Entry will be kept at a necessary minimum.

Dr. Daniel Farhey, Jacob Caspi Lodge, Haifa, Israel In fact, the "Ancient Mysteries' Magi" specialized in "science" as it was perceived in those days, with the considerable influence of their "specialization" in paganism. The sparse knowledge of the Magi and the surrounding society caused the secrecy and mysticism. At this period, special instructors called "Sophists" (scholars) were brought from Sicily. Opposed to the first and original Pythagoreans, the Sophists taught for pay and somehow abandoned the secrecy and mysticism. Hippocrates, a Pythagorean, was the principal combatant against the secrecy and published for the first time a book entitled "Principles". Subsequently, a very famous school was founded in Alexandria, Egypt, under Pythagorean influence. The most famous scholars were Euclid, Ptolemy, Menelaus, and Nicomachus, who revived the original Pythagorean theory. After the year A.D. 415, these theories did not continue to develop in Alexandria and the principal subject for research and study was theology, while the paganism passed away with the art of science. In the year A.D. 529, all the schools in Athens were closed according to an order of the Byzantine emperor Justinian I, thus ending one of the most brilliant periods in the development of mathematics and science. The philosophy and many theories on the Pythagorean way of life, transmitted orally by Pythagoras, were considerably influenced by the way of life of Judaism and the Bible, which was the only source explicitely prescribing the order. King Solomon lived about 400 years before Pythagoras. After the destruction of the First Temple of Jerusalem (586 B.C., before Pythagoras was born), under foreign and hostile rule, Jews gathered in regional schools. The five-pointed star (not six!) refered in Judaism "Solomon's Seal" and by the Greeks "pentagrama", was, in addition to the triangle, one of the symbols of the Pythagoreans. As known, the most ancient source of the pentagrama found by archeologists is Jewish. There is even a presumption that it was the symbol of the Jews before the six-pointed star "Shield of David".

Negotiating the Frontier (unpublished work in progress) Toledo and All That [An earlier version of this chapter was published as "Twelfth-Century Toledo and Strategies of the Literalist Trojan horse", Target 6/1 (1994), 43-66.] In asking this question, I am not really interested in whether there was a 'School of Toledo' in any capital-letter sense of the term, which is a matter for historians of glory. My concern is more literal and lower-case: What relation could there have been between translation and a little actual schooling, in the sense of teaching and learning things Arabic? My working hypothesis is that any translating associated with pedagogical activities must have been in some way related to the church. The principles of the translating might thus be sought in this relation. Further, if there was tension in the relation, the principles might be formulated in terms of a negotiation, hopefully in the form of a much better negotiation than anything the abbot of Cluny was able to achieve. What's in a School?

The first stage of creation consists in the emergence of light from a pure form that is close to God. In the second stage the splendor of closed form illuminates open form so that open form can pour on matter. One part of form is joined inseparably with pure matter, and the other part is joined with dirty matter. In the third stage, the light of sealed form causes the creation of the stars, which on the following day of creation influence the creation of living things.
