Hippias and his quadratrix Hippias of Elis (430 BC) was a sophist who invented the quadratrix curve to trisect an angle. The problem of trisecting a given angle was one of the problems that generated a lot of mathematics during this period, and several mathematicians devised methods for solving this problem. Like many other sophists, Hippias was an itinerant teacher who made his living wowing the locals with his knowledge. Apparently, he did alright, but didn't leave much of a legacy except for the quadratrix. Definition of the curve The curve can be described in a few sentences. Let ABCD denote a square. Over a unit time period, allow the top segment of the square to fall at a uniform speed to the bottom of the square. During the same time, allow the left side of the square to rotate clockwise at a uniform speed to the bottom of the square. At each time, the two segments will intersect in a point P. The totality of all these points P is defined as the quadratrix. Drawing the quadratrix One can imagine how Hippias might have sketched the quadratrix in the sand, but one can hardly image how he would have made an accurate sketch of it.

THE QUADRATRIX Trisecting an angle - Squaring the circle Introduction Three famous geometrical construction problems, originating from ancient Greek mathematics occupied many mathematicians until modern times. These problems are the duplication of the cube: construct (the edge of) a cube whose volume is double the volume of a given cube, angle trisection: construct an angle that equals one third of a given angle, the squaring of a circle: given (the radius of) a circle, construct (the side of) a square whose area equals the area of the circle. In the ancient Greek tradition the only tools that are available for these constructions are a ruler and a compass . During the 19th century the French mathematician Pierre Wantzel proved that under these circumstances the first two of those constructions are impossible and for the squaring of the circle it lasted until 1882 before a proof had been given by Ferdinand von Lindemann If we extend the range of tools the problems can be solved. New tools can be material tools (ex. a "marked ruler", that's a ruler with two marks on it, a "double ruler", that's a ruler with two parallel sides,...), or

Obvious is the most dangerous word in mathematics." (Eric Temple Bell ) PAPPUS (ca 300): An excellent mathematician who lived in Alexandria, Pappus attempted to rekindle interest in the mathematical works of the Greeks. This was not an easy task, since Christians had destroyed much of the ancient Greek documents, but Pappus managed to create his Mathematical Collection which cites or references over thirty different ancient mathematicians. Much of our knowledge of Greek mathematics has been derived from the works of Pappus. His work is often called the requiem of Greek mathematics. Great mathematicians whose works were revived by Pappus include Euclid Archimedes Apollonius Nicomedes , and Dinostratus Why did Herkimer have trouble making a phone call to the zoo?

Les mots mêmes de "mathématiques", "mathématiciens" ou leurs équivalents dans la plupart des langues européennes modernes sont d'origine grecque; ils dérivent du verbe "connaître, apprendre". Avant qu'à l'époque classique il ne prenne un sens plus spécialisé que nous lui attribuons aujourd'hui, le terme grec mathema, signifie "ce qui est enseigné", en fait toute forme de connaissance. The very words " mathematics " and " mathematician ", or their equivalents in most European languages, are derived from the Greek word meaning " to know " or " to learn ", Before the classical era, however, when it took on the specialized meaning that it has today, the Greek word mathema meant " that which is taught ", in other words all branches of knowledge.

BENEDICT M. ASHLEY, O.P.: THE ARTS OF LEARNING AND COMMUNICATION CHAPTER II The Science of Magnitudes THE BEGINNINGS THE GREEKS, SCIENTISTS AND ARTISTS In the last chapter we indicated that, while mathematical calculation was developed in a practical way by the people of Mesopotamia and Egypt, and carried still further by the Hindus and Chinese, it was the Greeks who made it a theoretical study. They transformed it into a true science, rigorously logical in structure, and a model for all other sciences. It was these same scientifically minded Greeks who first arrived at a perfect conception of the fine arts. The art of Mesopotamia was strong and grandiose, but without grace or subtlety. The art of Egypt was subtle and mysterious, but strangely static and without inner thought or feeling. Only in the art of Greece is there achieved a living balance of all the elements of beauty. Their art was classical (from Latin classicus ,meaning "first class"), and became a standard for all later art. Not, indeed, that art of later ages need confine itself to copying the style and subject-matter of Greek art, as some people have thought but that we can learn from Greek literature, sculpture, and architecture a true conception of the elements that go into a work of art and of the harmony with which they should be united. Today we are inclined to think of science and art as unrelated fields. The artist seems to be all imagination and emotion, living in a subjective world of free fancy. The scientist seems to be all facts and abstract theories, living in the objective world of experiment and measurement. Yet the Greeks excelled both in art and science. In order to learn something of this lesson from the Greeks in this chapter we are going to try to get clearer notions of two questions:
