Lecture 3 Hippocrates Quadrature of Lunes Greek mathematics The distinguishing feature of Greek mathematics is that it is concerned with logical development, not problem solving. We use the term Greek Mathematics to denote mathematics written in the Greek language between about -600 (Thales) and about 250 (Diophantos). The mathematicians were not necessarily ethnically Greek nor living in the region we now call Greece. In fact the major developments occurred in the Greek colonies now known as Turkey, Egypt and Italy. The Greeks did not have a sophisticated number system. The integers were expressed by concatenating the letters a-k for 19, and l-u for1090 etc. Special letters were invented for larger numbers. Later, Archimedes in the "Sand Reckoner", (in which he calculated the number of grains of sand needed to fill the Universe) developed an exponential system for arbitrarily large numbers. The Greeks used a decimal system for common purposes and a sexigesimal system for scientific purposes, for example astronomy. Concatenations of unit fractions were used for rationals, although later Diophantos developed special symbols for rationals. In Greek mathematics the numbers were 2,3,4,.. The unity 1 was not a number, but the unit in which the numbers were measured. There were no negative numbers or zero. Geometrical quantities such as line segments, angles, areas and volumes were called

Another person did all the work but never stated what the answer was. And the other person didn't understand what I was looking for. All in all, a pretty decent week. Here are some comments from Dale Pearson, who teaches at Highland Park Senior High School: It was surprising to most of my students that the two yellow figures must be equal in area. Only one student suspected that this might be the case before any calculations were made. Most students thought that the triangle was larger. A couple of students thought that the moon-shaped figure was larger. This was not the end of the surprises, however. Many students has difficulty finding any relationships whatsoever among the elements of the figure until they found a orderly way to keep track of their results.

Heath [6] recounts two versions of this story:- One version of the story is that [Hippocrates] was a merchant, but lost all his property through being captured by a pirate vessel. He then came to Athens to persecute the offenders and, during a long stay, attended lectures, finally attaining such proficiency in geometry that he tried to square the circle. Heath also recounts a different version of the story as told by Aristotle:- ... he allowed himself to be defrauded of a large sum by custom-house officers at Byzantium, thereby proving, in Aristotle's opinion, that, though a good geometer, he was stupid and incompetent in the business of ordinary life. The suggestion is that this 'long stay' in Athens was between about 450 BC and 430 BC.

Problem of Antiquity leads to Lunar Discovery by Mike Patterson Squaring the Circle " or " Quadrature of the Circle refers to a geometrical problem of antiquity. The problem was if you were given a circle of known area, could you create a square of the same area using only a compass and straightedge. "One of the earliest Greek mathematicians to attempt to treat the problem of the "quadrature of the circle" in pure geometric form, with the specific restriction that only compass and straightedge should be used, was Hippocrates of Chios (440 B.C.) He was able to show that the area of certain lunes (cresent-shaped figures formed by two intersecting arcs) could be represented exactly by trianglular (and hence rectangular) areas. For example, if AOB is a quadrant of a circle and AB is the diameter of a semicircle lying outside the quadrant, then the lune bounded by the semicircle and the quadrant has the same area as triangle AOB. His success with such special cases led him to suppose that he could eventually draw a polygon and hence a square whose area is exactly that of a circle." (P150 NCTM Yearbook #31) In 1882 Ferdinand Lindemann, modelling his proof after Hermite, proved that pi, also, is a transcendental number. No transcendental number is constructible, therefore Lindemann's result settled the famous problem concerning the possibility of "squaring the circle".

Hippocrates of Chios Introduction: the Area Problem The Babylonians, the Egyptians, and indeed every ancient civilization had knowledge of basic geometric concepts like how to calculate the areas of simple plane figures (triangles, squares, rectangles, parallelograms, trapezoids, and the like) and the volumes of simple solid bodies (parallelopipeds and pyramids). The Greeks however turned geometry into a real science by applying to it the deductive methods they were systematizing through philosophy. For the first time, epistemological questions were being studied about mathematical ideas: how do we know that the results we have discovered are true? Are these ideas interrelated? Dialectical reasoning strove to find the first principles of mathematical knowledge as a foundation for understanding the real world. This created an architecture of logical structure for mathematical ideas based on cause and effect relationships: if a certain theorem was a consequence of another, then the second was given an a priori precedence over the first. It became standard for geometers to communicate in a very spare language, consisting of statements of theorems followed by their proofs followed the next theorem in the logical development, with little in the way of discussion or explanation. It may not have had the same emotive force as the epic poetry of Homer, but it was beautiful in its own abstract way, like music to the listener. Moreover it was seen as uncovering the secrets of the physical universe, since physical objects and phenomena like light and sound behaved according to geometric principles.

34. Hippotext.html hippocrates of chios the quadrature of a lune 1. hippocrates of chios wasa merchant who fell in with a pirate ship and lost all his possessions. http://cerebro.cs.xu.edu/math/math147/02f/hippocrates/hippotext.html

Hippocrates of Chios: the quadrature of a lune From Philoponus Commentary on Aristotle's Physics Hippocrates of Chios was a merchant who fell in with a pirate ship and lost all his possessions. He came to Athens to prosecute the pirates and, staying a long time in Athens by reason of the indictment, consorted with philosophers, and reached such proficiency in geometry that he tried to affect the quadrature of the circle. He did not discover this, but having squared the lune he falsely thought from this that he could square the circle also. For he thought that from the quadrature of the lune the quadrature of the circle could also be calculated. From Simplicius Commentary on Aristotle's Physics Eudemus , however, in his History of Geometry says that Hippocrates did not demonstrate the quadrature of the lune on the side of a square but generally, as one might say. For every lune has an outer circumference equal to a semicircle or greater or less, and if Hippocrates squared the lune having an outer circumference equal to a semicircle and greater and less, the quadrature would appear to be proved generally. I shall set out what Eudemus wrote word for word, adding only for the sake of clearness a few things taken from Euclid's Elements on account of the summary style of Eudemus, who set out his proofs in abridged form in conformity with the ancient practice. He writes thus in the second book of the History of Geometry.

THE GREEK HEROIC AGE History THE HEROIC AGE (Vth century B.C.) One of the most important personalities of this century is Pericles Athens attracted intellectuals from all parts of the Greek world wanting to satisfy their thirst for knowledge. Rather than coming up with necessary solutions to practical problems at that time, the scholars were more interested in developing their own personal intellect. This desire for wisdom lead them to focus their learning on theoretical issues. During this period the three famous (or classical) problems were dealt with and two methods of reasoning were put into use The table below lists the mathematicians who lived during this period and the problems that formed the focus of their study.

G E R Lloyd Pluralism in Greek 'mathematics' Greek mathematike is not synonymous with English 'mathematics'. We should be wary of thinking of well-defined disciplines, such as mathematics and philosophy - and of specialists in them - before Plato (though there are some partial exceptions: Hippocrates of Chios was, so far as we know, mostly engaged in 'mathematike' broadly construed). Figures who cannot be defined exclusively as either 'mathematikos' or 'philosophos' include Philolaus, Archytas, Democritus, Eudoxus, not to speak of 'Thales' and 'Pythagoras' themselves (as tradition represents them). That throws some light on the old dispute between Knorr and Szabo on who 'invented' deductive argument ('philosophers' OR 'mathematicians'). Contributions to the discussion of the three 'traditional' mathematical problems (cf Knorr) come from different quarters and show evidence of attempts to police the borders . In squaring the circle, Aristotle and the commentators aim to discount the work of Antiphon and of Bryson, though they deem Hippocrates of Chios worthy of refutation. There is further input from 'sophists' (another indeterminate category) e.g. Protagoras' claim that the tangent does not touch the circle at a point. That may be classed as a metamathematical issue, but the boundaries between math.s and meta-math.s were/are hard to draw.

PreSocratics (7th - 5th century B.C.) Period marking the begining of science, as well as the development of literature, arts, politics, and philosophy. During these years, the city-states (polis in Greek) flourish. These include the Sparta and Athens. Within this period the Ionian school of natural philosophy was founded by Thales of Miletus . This is considered the first school for speculating about nature in a scientific way, hence signifies the birth of science. The Pythagorean brotherhood is formed by Pythagoras of Samos . This society performed a great deal of progress in mathematics, but also had mystical beliefs. In addition to the Ionian and Pythagorian, other schools of this period include the Eleatic , the Atomists, and the Sophists All philosophers - scientists up to Democritus are considered to be PreSocratics.
