Squaring the Circle a Case Study in the History of Mathematics the Problem
Squaring the Circle A Case Study in the History of Mathematics The Problem Using only a compass and straightedge, construct for any given circle, a square with the same area as the circle. The general problem of constructing a square with the same area as a given figure is known as the Quadrature of that figure. So, we seek a quadrature of the circle. The Answer It has been known since 1822 that the quadrature of a circle with straightedge and compass is impossible. Notes: First of all we are not saying that a square of equal area does not exist. If the circle has area A, then a square with side √A clearly has the same area. Secondly, we are not saying that a quadrature of a circle is impossible, since it is possible, but not under the restriction of using only a straightedge and compass. Precursors It has been written, in many places, that the quadrature problem appears in one of the earliest extant mathematical sources, the Rhind Papyrus (~ 1650 B.C.). This is not really an accurate statement. If one means by the “quadrature of the circle” simply a quadrature by any means, then one is just asking for the determination of the area of a circle. This problem does appear in the Rhind Papyrus, but I consider it as just a precursor to the construction problem we are examining. The Rhind Papyrus The papyrus was found in Thebes (Luxor) in the ruins of a small building near the Ramesseum.1 It was purchased in 1858 in Egypt by the Scottish Egyptologist A. -

Number Theory
“mcs-ftl” — 2010/9/8 — 0:40 — page 81 — #87 4 Number Theory Number theory is the study of the integers. Why anyone would want to study the integers is not immediately obvious. First of all, what’s to know? There’s 0, there’s 1, 2, 3, and so on, and, oh yeah, -1, -2, . Which one don’t you understand? Sec- ond, what practical value is there in it? The mathematician G. H. Hardy expressed pleasure in its impracticality when he wrote: [Number theorists] may be justified in rejoicing that there is one sci- ence, at any rate, and that their own, whose very remoteness from or- dinary human activities should keep it gentle and clean. Hardy was specially concerned that number theory not be used in warfare; he was a pacifist. You may applaud his sentiments, but he got it wrong: Number Theory underlies modern cryptography, which is what makes secure online communication possible. Secure communication is of course crucial in war—which may leave poor Hardy spinning in his grave. It’s also central to online commerce. Every time you buy a book from Amazon, check your grades on WebSIS, or use a PayPal account, you are relying on number theoretic algorithms. Number theory also provides an excellent environment for us to practice and apply the proof techniques that we developed in Chapters 2 and 3. Since we’ll be focusing on properties of the integers, we’ll adopt the default convention in this chapter that variables range over the set of integers, Z. 4.1 Divisibility The nature of number theory emerges as soon as we consider the divides relation a divides b iff ak b for some k: D The notation, a b, is an abbreviation for “a divides b.” If a b, then we also j j say that b is a multiple of a. -
Citations in Classics and Ancient History
Citations in Classics and Ancient History The most common style in use in the field of Classical Studies is the author-date style, also known as Chicago 2, but MLA is also quite common and perfectly acceptable. Quick guides for each of MLA and Chicago 2 are readily available as PDF downloads. The Chicago Manual of Style Online offers a guide on their web-page: http://www.chicagomanualofstyle.org/tools_citationguide.html The Modern Language Association (MLA) does not, but many educational institutions post an MLA guide for free access. While a specific citation style should be followed carefully, none take into account the specific practices of Classical Studies. They are all (Chicago, MLA and others) perfectly suitable for citing most resources, but should not be followed for citing ancient Greek and Latin primary source material, including primary sources in translation. Citing Primary Sources: Every ancient text has its own unique system for locating content by numbers. For example, Homer's Iliad is divided into 24 Books (what we might now call chapters) and the lines of each Book are numbered from line 1. Herodotus' Histories is divided into nine Books and each of these Books is divided into Chapters and each chapter into line numbers. The purpose of such a system is that the Iliad, or any primary source, can be cited in any language and from any publication and always refer to the same passage. That is why we do not cite Herodotus page 66. Page 66 in what publication, in what edition? Very early in your textbook, Apodexis Historia, a passage from Herodotus is reproduced. -
FROM HARMONIC ANALYSIS to ARITHMETIC COMBINATORICS: a BRIEF SURVEY the Purpose of This Note Is to Showcase a Certain Line Of
FROM HARMONIC ANALYSIS TO ARITHMETIC COMBINATORICS: A BRIEF SURVEY IZABELLA ÃLABA The purpose of this note is to showcase a certain line of research that connects harmonic analysis, speci¯cally restriction theory, to other areas of mathematics such as PDE, geometric measure theory, combinatorics, and number theory. There are many excellent in-depth presentations of the vari- ous areas of research that we will discuss; see e.g., the references below. The emphasis here will be on highlighting the connections between these areas. Our starting point will be restriction theory in harmonic analysis on Eu- clidean spaces. The main theme of restriction theory, in this context, is the connection between the decay at in¯nity of the Fourier transforms of singu- lar measures and the geometric properties of their support, including (but not necessarily limited to) curvature and dimensionality. For example, the Fourier transform of a measure supported on a hypersurface in Rd need not, in general, belong to any Lp with p < 1, but there are positive results if the hypersurface in question is curved. A classic example is the restriction theory for the sphere, where a conjecture due to E. M. Stein asserts that the Fourier transform maps L1(Sd¡1) to Lq(Rd) for all q > 2d=(d¡1). This has been proved in dimension 2 (Fe®erman-Stein, 1970), but remains open oth- erwise, despite the impressive and often groundbreaking work of Bourgain, Wol®, Tao, Christ, and others. We recommend [8] for a thorough survey of restriction theory for the sphere and other curved hypersurfaces. Restriction-type estimates have been immensely useful in PDE theory; in fact, much of the interest in the subject stems from PDE applications. -
The Number-System of Algebra : Treated Theoretically and Historically
- ; THE NUMBER-SYSTEM OF ALGEBRA TKEATED THEORETICALLY AND HISTORICALLY BY HENRY B. FINE, PH.D. PROFESSOR OF MATHEMATICS IN PRINCETON UNIVERSITY SECOND EDITION, WITH CORRECTIONS BOSTON, U.S.A. D. C. HEATH & CO., PUBLISHERS 1907 COPYRIGHT, 1890, BY HENRY B. FINE. 66 f 6 T PREFACE. THE theoretical part of this little book is an elementary of exposition the nature of the number concept, of the posi- tive integer, and of the four artificial forms of number which, with the positive integer, constitute the "number- " system of algebra, viz. the negative, the fraction, the irra- tional, and the imaginary. The discussion of the artificial numbers follows, in general, the same lines as my pam- phlet : On the Forms of Number arising in Common Algebra, but it is much more exhaustive and thorough- going. The point of view is the one first suggested by Peacock and Gregory, and accepted by mathematicians gen- erally since the discovery of quaternions and the Ausdeh- nungslehre of Grassmann, that algebra is completely defined formally by the laws of combination to which its funda- mental operations are subject; that, speaking generally, these laws alone define the operations, and the operations the various artificial numbers, as their formal or symbolic results. This doctrine was fully developed for the neg the fraction, and the imaginary by Hankel, in his Complexe Zahlensystemen, in 1867, and made complete by Cantor's beautiful theory of the irrational in 1871, but it has not as yet received adequate treatment in English. this kind is Any large degree of originality in work of from a naturally out of the question. -

Ancient Rhetoric and Greek Mathematics: a Response to a Modern Historiographical Dilemma
Science in Context 16(3), 391–412 (2003). Copyright © Cambridge University Press DOI: 10.1017/S0269889703000863 Printed in the United Kingdom Ancient Rhetoric and Greek Mathematics: A Response to a Modern Historiographical Dilemma Alain Bernard Dibner Institute, Boston To the memory of three days in the Negev Argument In this article, I compare Sabetai Unguru’s and Wilbur Knorr’s views on the historiography of ancient Greek mathematics. Although they share the same concern for avoiding anach- ronisms, they take very different stands on the role mathematical readings should have in the interpretation of ancient mathematics. While Unguru refuses any intrusion of mathematical practice into history, Knorr believes this practice to be a key tool for understanding the ancient tradition of geometry. Thus modern historians have to find their way between these opposing views while avoiding an unsatisfactory compromise. One approach to this, I propose, is to take ancient rhetoric into account. I illustrate this proposal by showing how rhetorical categories can help us to analyze mathematical texts. I finally show that such an approach accommodates Knorr’s concern about ancient mathematical practice as well as the standards for modern historical research set by Unguru 25 years ago. Introduction The title of the present paper indicates that this work concerns the relationship between ancient rhetoric and ancient Greek mathematics. Such a title obviously raises a simple question: Is there such a relationship? The usual appreciation of ancient science and philosophy is at odds with such an idea. This appreciation is rooted in the pregnant categorization that ranks rhetoric and science at very different levels. -
Diophantus of Alexandria
Diophantus of Alexandria Diophantus of Alexandria played a major role in the development of algebra and was a considerable influence on later number theorists. Diophantine analysis, which is closely related to algebraic geometry, has experienced a resurgence of interest in the past half century. Diophantus worked before the introduction of modern algebraic notation, but he moved from rhetorical algebra to syncopated algebra, where abbreviations are used. Prior to Diophantus’ time the steps in solving a problem were written in words and complete sentences, like a piece of prose, or a philosophical argument. Diophantus employed a symbol to represent the unknown quantity in his equations, but as he had only one symbol he could not use more than one unknown at a time. His work, while not a system of symbols, was nevertheless an important step in the right direction. François Viète, influenced by Napier, Descartes and John Wallis, introduced symbolic algebra into Europe in the 16th century when he used letters to represent both constants and variables. Claims that Diophantus lived from about 200 to 284 and spent time at Alexandria are based on detective work in finding clues to the times he flourished in his and others’ writings. Theon of Alexandria quoted Diophantus in 365 and his work was the subject of a commentary written by Theon’s daughter Hypatia at the beginning of the 5th century, which unfortunately is lost. The most details concerning Diophantus’ life are found in the Greek Anthology, compiled by Metrodorus around 500. Diophantus is often referred to as the “father of algebra,” but this is stretching things as many of his methods for solving linear and quadratic equations can be traced back to the Babylonians. -

Handwriting recognition has attracted many script in [3]. In [6], SVM approach is used to recognize researchers across the world since many years. Recognition of strokes in Telugu script. The set of strokes are segmented into online handwritten Devanagari numerals is a goal of many subsets based on the relative position of the stroke in a research efforts in the pattern recognition field The main goal of character. An SVM based classifier is built for recognition of the work is the recognition of online hand written Devanagari strokes in each subset. A rule based approach is used to numerals using support vector machine. In the data collection recognize a character from the sequence of stroke classes phase, co-ordinate points of the input handwritten numeral are given by the stroke classifier. -
Calculation and Controversy
calculation and controversy The young Newton owed his greatest intellectual debt to the French mathematician and natural philosopher, René Descartes. He was influ- enced by both English and Continental commentators on Descartes’ work. Problems derived from the writings of the Oxford mathematician, John Wallis, also featured strongly in Newton’s development as a mathe- matician capable of handling infinite series and the complexities of calcula- tions involving curved lines. The ‘Waste Book’ that Newton used for much of his mathematical working in the 1660s demonstrates how quickly his talents surpassed those of most of his contemporaries. Nevertheless, the evolution of Newton’s thought was only possible through consideration of what his immediate predecessors had already achieved. Once Newton had become a public figure, however, he became increasingly concerned to ensure proper recognition for his own ideas. In the quarrels that resulted with mathematicians like Gottfried Wilhelm Leibniz (1646–1716) or Johann Bernoulli (1667–1748), Newton supervised his disciples in the reconstruction of the historical record of his discoveries. One of those followers was William Jones, tutor to the future Earl of Macclesfield, who acquired or copied many letters and papers relating to Newton’s early career. These formed the heart of the Macclesfield Collection, which has recently been purchased by Cambridge University Library. 31 rené descartes, Geometria ed. and trans. frans van schooten 2 parts (Amsterdam, 1659–61) 4o: -2 4, a-3t4, g-3g4; π2, -2 4, a-f4 Trinity* * College, Cambridge,* shelfmark* nq 16/203 Newton acquired this book ‘a little before Christmas’ 1664, having read an earlier edition of Descartes’ Geometry by van Schooten earlier in the year.
