Extractions: Version for printing Most of what we know of Theaetetus 's life comes from the writing of Plato . It is clear that Plato held Theaetetus in the highest regard and he wrote two dialogues which had Theaetetus as the principal character, one of the dialogues being Theaetetus while the other is the Sophist In Theaetetus a discussion between Socrates , Theaetetus and his teacher Theodorus of Cyrene is recorded. This conversation took place in 399 BC and Theaetetus is described as a youth at the time. This allows us to give a fairly accurate date for Theaetetus's birth (although some have claimed that the Greek word could describe a man of up to 21 years old). Again from Plato we learn that Theaetetus's father, Euphronius of Sunium, was a wealthy man and left a large fortune. However, the money was squandered by the trustees of the will but despite this Theaetetus was generous to all around him. In appearance Theaetetus had a snub nose and protruding eyes but he is described by Plato as having a beautiful mind and he is also described as being the perfect gentleman.

Extractions: During the 4th century B.C., Greek geometry burst its bonds and went on to the tremendous discoveries of the "age of giants." And Greek culture, too, burst from the mainland of Hellas and spread to most of the eastern Mediterranean. Both developments were connected with the romantic figure of Alexander the Great. After Plato's time, teachers and alumni from the Academy had gone on to found schools of their own. In particular, Plato's most famous associate, the great philosopher Aristotle, had set up the Lyceum in Athens, and started the systematic classification of human knowledge. And Aristotle's most renowned pupil was the warrior king Alexander of Macedon, who tried to conquer the world. In thirteen years, Alexander extended his rule over Greece proper, and Ionia, Phoenicia, Egypt, and the vast Persian domains as far as India. Then he died, and his empire broke up. But throughout those far-flung lands, he had founded Greek cities and planted the seeds of Greek civilization-the Greek language, Greek art, and, of course, Greek mathematics. Mathematicians traveled with his armies. And there is even a

The geometry of Babylon (in Mesopotamia) and Egypt was mostly experimentally derived rules used by the engineers of those civilizations. They knew how to compute areas, and even knew the "Pythagorian Theorem" 1000 years before the Greeks (see: Pythagoras's theorem in Babylonian mathematics ). But there is no evidence that they logically deduced geometric facts from basic principles. Nevertheless, they established the framework that inspired Greek geometry.

Extractions: updated 1/8/2005 selected entries from The Oxford Dictionary of Philosophy Simon Blackburn Note: Blackburn s dictionary is a highly recommended reference book for philosophy students. philosophy (Gk., love of knowledge or wisdom) The study of the most general and abstract features of the world and categories with which we think: mind, matter, reason, proof, truth, etc. In philosophy, the concepts with which we approach the world themselves become the topic of enquiry. A philosophy of a discipline such as history, physics, or law seeks not so much so solve historical, physical, or legal questions, as to study the concepts that structure such thinking, and to lay bare their foundations and presuppositions. In this sense philosophy is what happens when a practice becomes self-conscious. . . . Thales of Miletus (flourished 585 BC) One of the Seven Sages of ancient Greece and judged by Aristotle to be the founder of physical science; that is, he was the first Greek to search for the ultimate substance of things, which he identified with water. A polymath, he is supposed to have predicted the solar eclipse of 28 May 585 BC and to have introduced the study of geometry to Greece. He apparently believed in some kind of hylozoism and panpsychism, but claims made in late antiquity about his doctrines and discoveries are regarded as unreliable. Anaximander of Miletus (c. 610-c. 547/6 BC) The first Greek philosopher and astronomer whose thought is known in any detail. Anaximander constructed the first precise geometrical model of the universe, and produced maps of both the earth and the heavens. His intentions included the

Extractions: The Red Cross and other charities also need your help. Okay, so who thinks this should redirect to Euclid ? Can we have a show of hands, please? Actually, I think it might be nice to concentrate on Euclid's life in his article, even though we don't know much about it. I think this story this page manages to talk about it for a few paragraphs before getting to the mathematical details, so it could work. Then we could put the actual maths in this article. What do you think? Oliver P. 00:21 15 Jun 2003 (UTC) I've expanded the material on this page quite a bit. Looking at the material in the entry on "Euclid," most of it seems to be duplicated here. Unless we can find some more significant biographical information (are other sources than MacTutor available?), I agree that the articles should be merged. JPB 06:16 6 Jul 2003 (UTC) Well, this article could go through the books one by one, and summarise what is proven in each one. That would quite nice for this article, but would be a bit overwhelming if put into in the article on Euclid himself, which concentrates more on the overall significance of his work.
