"Not the least unexpected thing about Mathematics and the Unexpected is that a real mathematician should write not just a literate work, but a literary one."—Ian Stewart, New Scientist "In this brief, elegant treatise, assessable to anyone who likes to think, Ivar Ekelund explains some philosophical implications of recent mathematics. He examines randomness, the geometry involved in making predictions, and why general trends are easy to project (it will snow in January) but particulars are practically impossible (it will snow from 2 p.m. to 5 p.m. on the 21st)."—Village Voice

Optimists believe this is the best of all possible worlds. And pessimists fear that might really be the case. But what is the best of all possible worlds? How do we define it? Is it the world that operates the most efficiently? Or the one in which most people are comfortable and content? Questions such as these have preoccupied philosophers and theologians for ages, but there was a time, during the seventeenth and eighteenth centuries, when scientists and mathematicians felt they could provide the answer. This book is their story. Ivar Ekeland here takes the reader on a journey through scientific attempts to envision the best of all possible worlds. He begins with the French physicist Maupertuis, whose least action principle asserted that everything in nature occurs in the way that requires the least possible action. This idea, Ekeland shows, was a pivotal breakthrough in mathematics, because it was the first expression of the concept of optimization, or the creation of systems that are the most efficient or functional. Although the least action principle was later elaborated on and overshadowed by the theories of Leonhard Euler and Gottfried Leibniz, the concept of optimization that emerged from it is an important one that touches virtually every scientific discipline today. Tracing the profound impact of optimization and the unexpected ways in which it has influenced the study of mathematics, biology, economics, and even politics, Ekeland reveals throughout how the idea of optimization has driven some of our greatest intellectual breakthroughs. The result is a dazzling display of erudition—one that will be essential reading for popular-science buffs and historians of science alike.

Ivar Ekeland extends his consideration of the catastrophe theory of the universe begun in his widely acclaimed Mathematics and the Unexpected, by drawing on rich literary sources, particularly the Norse saga of Saint Olaf, and such current topics as chaos theory, information theory, and particle physics. "Ivar Ekeland gained a large and enthusiastic following with Mathematics and the Unexpected, a brilliant and charming exposition of fundamental new discoveries in the theory of dynamical systems. The Broken Dice continues the same theme, and in the same elegant, seemingly effortless style, but focuses more closely on the implications of those discoveries for the rest of human culture. What are chance and probability? How has our thinking about them been changed by the discovery of chaos? What are all of these concepts good for? . . . Ah, but, I mustn't give the game away, any more than I should if I were reviewing a detective novel. And this is just as gripping a tale. . . . Beg, borrow, or preferably buy a copy. . . . I guarantee you won't be disappointed."—Ian Stewart, Science

Alex im Wunderland der Zahlen

Eine Reise durch die aufregende Welt der Mathematik

Erinnern wir uns nicht alle mit Schrecken an die ratlosen Momente vor der Tafel im Matheunterricht? Mit Kurvendiskussionen und Dreisatz dürften jedenfalls nur wenige Spaß und Spannung verbinden... Bis jetzt! Denn nun wagt sich Alex Bellos in den Kaninchenbau der Mathematik: in das Reich von Geometrie und Algebra, von Wahrscheinlichkeitsrechnung, Statistik und logischen Paradoxa. Auf der anderen Seite des Erdballs, am Amazonas, zählen die Mitglieder des Indianerstammes der Munduruku nur bis fünf und halten die Vorstellung, dass dies nicht genügen solle, für reichlich lächerlich. Bei uns in Deutschland dagegen finden jährlich die Meisterschaften der besten Kopfrechner der Welt statt - 2010 wurde in Magdeburg eine elfjährige Inderin zur Nummer eins unter den "Mathleten" gekürt. Die Mathe-Weltmeisterin unter den Tieren ist hingegen die Schimpansin Ai, die Alex Bellos im japanischen Inuyama aufspürt und über deren Rechenkünste er nur staunen kann. Auch wenn er von den bahnbrechenden Überlegungen Euklids erzählt oder erklärt, warum man in Japan seine Visitenkarten keinesfalls zu Dodekaedern falten sollte - Bellos führt uns durch das wahrhaft erstaunliche Reich der Zahlen und bringt uns eine komplexe Wissenschaft spielerisch nahe. Mit seiner Mischung aus spannender Reportage, Wissenschaftsgeschichte und mathematischen Kabinettstückchen erbringt er souverän den Beweis, dass die Gleichung Mathematik = Langeweile eindeutig nicht wahr ist. Quod erat demonstrandum.

Unexpected Links between Egyptian and Babylonian Mathematics

Author: Jöran Friberg

Publisher: World Scientific

ISBN: 9814480401

Category: Science

Page: 308

View: 2660

Mesopotamian mathematics is known from a great number of cuneiform texts, most of them Old Babylonian, some Late Babylonian or pre-Old-Babylonian, and has been intensively studied during the last couple of decades. In contrast to this Egyptian mathematics is known from only a small number of papyrus texts, and the few books and papers that have been written about Egyptian mathematical papyri have mostly reiterated the same old presentations and interpretations of the texts. In this book, it is shown that the methods developed by the author for the close study of mathematical cuneiform texts can also be successfully applied to all kinds of Egyptian mathematical texts, hieratic, demotic, or Greek-Egyptian. At the same time, comparisons of a large number of individual Egyptian mathematical exercises with Babylonian parallels yield many new insights into the nature of Egyptian mathematics and show that Egyptian and Babylonian mathematics display greater similarities than expected. Contents:Two Curious Mathematical Cuneiform Texts from Old Babylonian MariHieratic Mathematical Papyri and Cuneiform Mathematical TextsDemotic Mathematical Papyri and Cuneiform Mathematical TextsGreek-Egyptian Mathematical Documents and Cuneiform Mathematical Texts Readership: Mathematicians, historians of science, egyptologists and assyriologists. Keywords:Babylonian Mathematics;Egyptian Mathematics;Greek Mathematics;Mathematical Cuneiform Texts;Mathematical Papyri;Ancient Mathematics;Early Mathematics;History of Mathematics;Demotic Texts;Hieratic TextsKey Features:Extensive surveys of known Egyptian mathematical textsNew interpretations of particularly difficult Egyptian or Babylonian mathematical exercisesMany detailed diagrams and figures, using computer-aided methods of presentationsInteresting observations of experiments with new ways of representing fractions in demotic and Greek-Egyptian mathematical texts

47 brauchen nur den Nenner n so groß zu wählen, daß das Intervall [0, IJn] kleiner wird als das fragliche Intervall [A, B], dann muß mindestens einer der Brüche m/n innerhalb des Intervalls liegen. Also kann es kein noch so kleines Intervall auf der Achse geben, das von rationalen Punkten frei wäre. Es folgt weiterhin, daß es in jedem Intervall unendlich viele rationale Punkte geben muß; denn wenn es nur eine endliche Anzahl gäbe, so könnte das Intervall zwischen zwei beliebigen benachbarten Punkten keine rationalen Punkte enthalten, was, wie wir eben sahen, unmöglich ist. § 2. Inkommensurable Strecken, irrationale Zahlen und der Grenzwertbegriff 1. Einleitung Vergleicht man zwei Strecken a und b hinsichtlich ihrer Größe, so kann es vor kommen, daß a in b genau r-mal enthalten ist, wobei r eine ganze Zahl darstellt. In diesem Fall können wir das Maß der Strecke b durch das von a ausdrücken, indem wir sagen, daß die Länge von b das r-fache der Länge von a ist.

Locks, Mahabharata And Mathematics : AnExploration Of Unexpected Parallels

A delightful exercise in lateral thinking There could be no three more disparate things than locks, mathematics and the Mahabharata. However, as Locks Mahabharata Mathematics shows, this is as entertaining a combination as any. Given here is a treasure trove of stories drawn from all three subjects. What could be more beguiling than a book that mixes Draupadi, a lock with five keys, and the quirky world of polynomials? Or Jarasandha who could be split apart but whose two halves could never be kept separate - split locks and symmetries? The Mahabharata is known for its stories. Lesser known are the fascinating combinations of locks which Dr Raghu - an avid collector - throws light upon, or the esoteric world of pure mathematics that he conveys for a lay audience. Divided into ten chapters, Locks Mahabharata Mathematics has stories ranging from that of Draupadi, to Yudhishthira's gamble, to Shukrayacharya and Kacha. Keeping them company are chancy locks, interacting keys and binary stars. Profusely illustrated with drawings of locks from his personal collection, this is a neatly original book like few others. Recalling books such as The Mind's I, Fantasies and Reflections on Self and Soul, The Tipping Point, and Godel, Escher, Bach ..., underlying it is a simple principle, one might say: Pure logic is the ruin of the spirit, as Antoine de Saint-Exupery said. These are tales that combine reason with fantasy to elevate the spirit.

Energy and the Unexpected

Author: Keith James Laidler

Publisher: Oxford University Press, USA

ISBN: 9780198525165

Category: Language Arts & Disciplines

Page: 146

View: 7740

Only in the early 19th century did scientists recognize that energy is a distinct physical quantity. Since then, however, it has played a pivotal role in the advancement and the understanding of science and in technology. From the steam engine to the equation e=mc2 and beyond, the concept of energy offers an essential key to our understanding of the Universe. In this entertaining and highly readable book, Professor Laidler explains the concept of energy and its characteristics as theywere discovered over the past two centuries. He describes how energy transformations, as interpreted by the second law of thermodynamics, are not absolute but can only be understood in terms of chance and probability. After looking at energy on a small scale and then at the scale of the Universe itself, he shows how these topics are linked with chaos theory according to which the unexpected is inevitable. Written for the general reader with an interest in science, the development and interrelationship of the concepts of energy, chance and chaos are set in their historical context, and illuminated by accounts of the key scientists involved and of some of their investigations.
