15 November 2002 Ancient Text Shakes Up the History of Pre-Calculus BY John Sanford Reprinted from The Stanford Report, November 6, 2002 R eviel Netz, an assistant professor of classics, might not have actually shouted "Eureka!" on a visit last year to the Walters Art Museum in Baltimore, but that's what he was thinking. A scholar of Greek mathematics, Netz was hanging out with one of his colleagues and frequent collaborators, Professor Ken Saito of the Osaka Prefecture University in Japan, when they flew together to Baltimore in January 2001 to look at a recently rediscovered codex of Archimedes treatises. "It was basically just tourism," Netz recalled. On a lark they examined a theretofore unread section of The Method of Mechanical Theorems , which is the book's biggest claim to fame; no other copy of the work is known to exist. What they discovered made their jaws drop. A section from The Archimedes Palimpsest, which classics Professor Reviel Netz stumbled on during a visit to the Walters Art Museum in Baltimore. Closer examination showed the Greeks understood the concept of infinity. Missing The Archimedes Palimpsest, as the book is called, is in terrible shape. (A palimpsest is a manuscript that has been written on more than once; in this case, a 13th-century Greek prayer book overlays the 10th-century script of the treatises.) The pages have been battered, gouged, scorched by fire and blotched by fungus. Without the use of computer technology, they would be mostly unreadable.

But when the palimpsest caught the attention of the great Danish philologist Johan Ludvig Heiberg in 1906, the underlying script was much more legible. At that time, the volume was in a library collection in Constantinople - present-day Istanbul - and, until Heiberg went to examine it, nobody seems to have realized its importance; the book contained the ancient Greek mathematician's previously unknown treatise on The Method of Mechanical Theorems.

45. The Classical Greek Problems The greek mathematicians thus needed to find a way to construct this quantity The ancient greek mathematicians also could not find a proof for angle http://www.math.rutgers.edu/courses/436/Honors02/classical.html

The Classical Greek Problems Patricia DiJoseph There were three problems that the ancient Greeks (600BC to 400AD) tried unsuccssfully to solve by Euclidean methods, all of which were proven unsolvable by these means as much as two thousand years later, as a result of progress in algebra, and the idea of analytic geometry in the sense of Descartes. The Greeks wanted to solve these problems using only a Euclidean constructions, or as they themselves called them, "plane" methods. Though they were never able to do so ( as they cannot be done this way, they did find a series of remarkably clever constructions using more powerful techniques, involving so-called "solid" and "mechanical" methods, as well as a technique called "verging". Then, in the 19th century, the impossibility of finding purely Euclidean constructions for these problems was finally proved. The three classical Greek problems were problems of geometry: doubling the cube, angle trisection, and squaring a circle. Duplication of the cube is the problem of determining the length of the sides of a cube whose volume is double that of a given c ube. A cube by definition is a three dimensional shape comprised of a height, width, and depth all of the same magnitude s. To find its volume, one multiplies the length (s) by the width (s) and then by the depth (s): the volume is s(s(s or s3. Diagram not converted, here and below

Greek Mathematicians Pythagoras (500 BC) He developed the first general proof of the Pythagorean theorem. The square of the longest side of the right triangle equals the sum of the squares of the other two sides. He discovered the existence of irrational numbers and created doctrines which inspired the systematic study of mathematics and the numeral aspects of musical harmony. Plato (428-348 BC) One of the world's greatest philosophers, he expanded Greek learning throughout the world in astronomy, mathematics, and metaphysics. He developed the Academy and taught philosophy and different levels of mathematics as well as theoretical astronomy. Euclid (300 BC) Euclid made great Advancements in Geometry. He developed the revolutionary progress in the analysis of two and three- dimensional space. He created the geometry that endures to this day known as Euclidean Geometry. Archimedes (287-212 BC) He determined the areas and volumes of numerous geometric figures and derived equations for them. Eratosthenes (275-194 BC) He pioneered mathematical geography. He caculated the circumference of the earth with astonishing accuracy for his time.

The Attic system, in use from 600 bc to 200 bc , used a stroke for 1 and the initial letters of the words for 5, 10, 100, 1,000, and 10,000—namely, the initials of pente deka hekaton khilioi , and myrioi —to represent the respective numbers. A later system assigned number values to the 24 letters of the Greek alphabet and to 3 other letters that were no longer used. The letters could be combined to form numbers through 999. For higher numbers, a stroke preceding the initial letter (1 through 9) indicated a multiple of 1,000 (1,000 through 9,000). For 10,000 and above, the symbol M indicated that the numeral below should be multiplied by 10,000. See also Numerals b Pythagoras and the Pythagoreans Pythagoras taught the importance of studying numbers in order to understand the world. We know of his achievements only from his disciples, the Pythagoreans, who made important discoveries about number theory and geometry. The Pythagoreans represented whole numbers by using arrangements of dots or pebbles, and classified these numbers according to the shapes produced. (The English word

Username: Password: Sites for teachers Sites for parents Awards Interactive Activities ... Sites for parents Four Problems Of Antiquity Three geometric questions raised by the early Greek mathematicians attained the status of classical problems in Mathematics. These are: Doubling of the cube Construct a cube whose volume is double that of a given one. Angle trisection Trisect an arbitrary angle. Squaring a circle Construct a square whose area equals that of a given circle. Often another problem is attached to the list: Construct a regular heptagon (a polygon with 7 sides.) The problems are legendary not because they did not have solutions, or the solutions they had were unusually hard. No, numerous simple solutions have been found yet by Greek mathematicians. The problem was in that all known solutions violated an important condition for this kind of problems, one condition imposed by the Greek mathematicians themselves: Valid solutions to the construction problems are assumed to consist of a finite number of steps of only two kinds: drawing a straight line with a ruler (or rather a straightedge as no marks are allowed on the ruler) and drawing a circle. You are referred to solutions of problems and as examples of existent solutions. That no solution exists subject to the self-imposed constraints have been proven only in the 19th century.

Chapter 1: Mathematical Preliminaries Table of Contents 1.A Introduction These ancients understood how to figure the area of the polygon, but they were never convinced that the area of the polygon would ever exactly match that of the circle, regardless of how large N grew. This conceptual hurdle was so high that it stood as a barrier for 2,000 years before it was cleared by the great minds of the 17th century who invented the concept of limits which is fundamental to the Calculus (Boyer, 1949) . My teaching experience suggests there are still a great many ancient Greeks in our midst, and they usually show their colors first in Fourier analysis when attempting to make the transition from discretely sampled functions to continuous functions. When geometrical intuition fails, analytical reasoning may come to the rescue. If the location of a point in 3-dimensional space is just a list of three numbers (x,y,z), then to locate a point in 4-dimensional space we only need to extend the list (w,x,y,z) by starting a bit earlier in the alphabet! Similarly, we may get around some conceptual difficulties by replacing geometrical objects and manipulations with analytical equations and computations. For these reasons, the early chapters of these coursenotes will carry a dual presentation of ideas, one geometrical and the other analytical. It is hoped that the redundancy of this approach will help the student achieve a depth of understanding beyond that obtained by either method alone.

Lisa Raphals and celestial distances, including the distance to the ¡§ends of the earth¡¨ and the ¡§height of heaven.¡¨ They incorrectly assumed that the earth was flat, but correctly assumed that the sun was a finite, and measurable, distance from the earth. Their calculations were less accurate than Eratosthenes¡¦, but no less mathematically well reasoned. Similar Triangles in Greek Astronomy During the third century B.C.E., Greek mathematicians and astronomers developed hypotheses and calculations regarding the motion and sizes and distance of the sun, moon and earth. Aristarchus of Samos (310-230 B.C.E.) is best known as the first Greek exponent of a heliocentric theory, a view that his contemporaries rejected because it conflicted with the commonsense view that the earth did not move. In his one surviving work, he used assumptions and the properties of similar triangles to ¡§demonstrate¡¨ ratios between the diameters of the earth, sun and moon and their distances from each other. For example: ¡§The distance of the sun from the earth is greater than 18 times, but less than 20 times the distance of the moon from the earth.¡¨ The Greek text is a list of procedures for naming points and drawing lines and circles between them, with no visual representation. (Modern editions and translations typically add an illustrative diagram.) The Greek text has the look and feel of a proof by deduction from the properties of similar triangles, rather than calculation from actual measurements.

Indic Mathematics: India and the Scientific Revolution Dr. David Gray 1. Math and Ethnocentrism The study of mathematics in the West has long been characterized by a certain ethnocentric bias, a bias which most often manifests not in explicit racism, but in a tendency toward undermining or eliding the real contributions made by non-Western civilizations. The debt owed by the West to other civilizations, and to India in particular, go back to the earliest epoch of the "Western" scientific tradition, the age of the classical Greeks, and continued up until the dawn of the modern era, the renaissance, when Europe was awakening from its dark ages. This awakening was in part made possible by the rediscovery of mathematics and other sciences and technologies through the medium of the Arabs, who transmitted to Europe both their own lost heritage as well as the advanced mathematical traditions formulated in India. George Ghevarughese Joseph, in an important article entitled "Foundations of Eurocentrism in Mathematics," argued that "the standard treatment of the history of non-European mathematics is a product of historiographical bias (conscious or otherwise) in the selection and interpretation of facts, which, as a consequence, results in ignoring, devaluing or distorting contributions arising outside European mathematical traditions." (1987:14) Due to the legacy of colonialism, the exploitation of which was ideologically justified through a doctrine of racial superiority, the contributions of non-European civilizations were often ignored, or, as Joseph argued, even distorted, in that they were often misattributed as European, i.e. Greek, contributions, and when their contributions were so great as to resist such treatment, they were typically devalued, considered inferior or irrelevant to Western mathematical traditions.

Includes information about key people during this time period. http://www-history.mcs.st-and.ac.uk/history/HistTopics/Arabic_mathematics.html

Arabic mathematics : forgotten brilliance? Alphabetical list of History Topics History Topics Index Version for printing Recent research paints a new picture of the debt that we owe to Arabic/Islamic mathematics. Certainly many of the ideas which were previously thought to have been brilliant new conceptions due to European mathematicians of the sixteenth, seventeenth and eighteenth centuries are now known to have been developed by Arabic/Islamic mathematicians around four centuries earlier. In many respects the mathematics studied today is far closer in style to that of the Arabic/Islamic contribution than to that of the Greeks. There is a widely held view that, after a brilliant period for mathematics when the Greeks laid the foundations for modern mathematics, there was a period of stagnation before the Europeans took over where the Greeks left off at the beginning of the sixteenth century. The common perception of the period of 1000 years or so between the ancient Greeks and the European Renaissance is that little happened in the world of mathematics except that some Arabic translations of Greek texts were made which preserved the Greek learning so that it was available to the Europeans at the beginning of the sixteenth century. That such views should be generally held is of no surprise. Many leading historians of mathematics have contributed to the perception by either omitting any mention of Arabic/Islamic mathematics in the historical development of the subject or with statements such as that made by Duhem in [3]:-
