Regular Convex Polytopes A Short Historical Overview, Regular Polytopes And N-di Plato founded a school in Athens "the Academy".

Extractions: For those who are unfamiliar with this topic an outline of major discoveries is given below in chronological order: Phytagoras born about 569 BC in Samos, Ionia Greece, died about 475 BC. Although early findings acknowledged by mathematicians and historians date back before the time of Phytagoras like the Babylonians who were aquainted with the famous Pythagoras's theorem c^2=a^2+b^2 as early as 3750 BC, this was not discoverd until 1962. Some of the first basic geometric theorems are credited to Phytagoras. Phytagoras is often called the first pure mathematician; he founded a school "the semicircle" and many pupils elaborated on his findings and thoughts.

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

Theaetetus theaetetus of athens. The first states (see for example 1) Theaetetus, ofAthens, astronomer, philosopher, disciple of Socrates, taught at Heraclea. http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Theaetetus.html
Extractions: 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: Previous (Alphabetically) Next Welcome page Theaetetus studied with Theodorus of Cyrene and at the Academy with Plato Theaetetus was the first to study the octahedron and the icosahedron. Euclid 's 10th and 13th books are almost certainly a description of Theaetetus's work. This means that it was Theaetetus's work on irrational lengths which is described in the 10th book, thought by many to be the finest work of the Elements. Theaetetus is also thought to be the author of the theory of proportion which appears in Eudoxus 's work.

Extractions: In Euclid 's Elements , Theaetetus is credited with discovering the octahedron and icosahedron. Theaetetus also proved the existence of irrational numbers, a discovery that rendered many Pythagorean proofs as invalid and threw the Greek mathematical community into a crisis. This problem was soon solved by Eudoxus . It is not entirely clear if Eudoxus ' theory of proportions, which allowed him to solve the irrationality crisis actually came from Theaetetus but as we have no evidence to the contrary, Eudoxus has generally been given that credit.

Extractions: Clearly, the art of designing tilings and patterns is very old and well developed. But also the science of tilings and patterns, i.e. the study of their mathematical properties, has its roots in antiquity. One of the earliest known results in mathematics is the enumeration of all regular polyhedra, the five Platonic solids, which were treated mathematically by Theaetetus of Athens and in Euclid's Elements over 2000 years ago. The classification of all 13 semi-regular polyhedra goes back to Archimedes and earlier. A further milestone is Kepler's work (1571-1630) on 2- and 3-dimensional packings and tilings, such as the classification of all Archimedian tilings of the plane. The theory of Delaney symbols, introduced by Andreas Dress (1984, 1987) and inspired by Mathew Delaney (1980), provides a suitable combinatorial framework for formulating, studying and solving classification problems concerning periodic tilings of simply connected manifolds. In this approach, any given d-dimensional periodic tiling is described in terms of its Delaney symbol (D,m), which can also be interpreted as a finite, connected edge- -colored graph with maps defined on its vertices. Based on all this, it seems natural to attempt to develop a computational approach to the theory of tilings, the fundamental idea being to transform problems concerning periodic tilings, symmetric polytopes and symmetry groups into combinatorial problems in terms of Delaney symbols which one then can address and solve using methods of symbolic calculation from combinatorics, algebra and geometry.

Extractions: 1.2 Tiling and Patterns The art of tiling and patterns has been developed over the millennia, with ancient tillings and mosaics found, for example, in ancient Roman mosaics, such as the one on the left . This mosaic displays the classic properties of any tiling, with shapes repeating to from a tightly packed planar surface with no apparent gaps. The drosophila eye can be viewed as a tiling of perfectly hexagonal tiles. To accurately study this one must look at the science of tilings. Tilings can be viewed not simply as works of art, but as mathematically and scientifically intriguing complex field. This field has existed for almost as long as the tilings themselves. Theaetetus of Athens began work into the science of tiling over 2000 years ago. Other famous mathematicians in this field include Archimedes and Kepler. An example of Keplers work is shown to the right. To evaluate the implications on fly eye growth using this science, an assessment of similar tilings, consisting of regular polygons must be carried out. As was known back in Archimedes time, there are only three regular polygons, (angles and side lengths uniform) that will tessellate. These are the triangle, square and regular hexagon. Tilings of these are shown below
