This is a truly unique book. It is written with wit and style and is a part of folk mathematics.","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":50168268456209,"sku":"GOR003778352","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ GOOD \/ SBYB","offer_id":53395206734097,"sku":"CIN0883855070G","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ GOOD \/ INTERNAL","offer_id":53557306196241,"sku":"GOR005265209","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0883855070.jpg?v=1751108135"},{"product_id":"trisectors-book-underwood-dudley-9780883855140","title":"The Trisectors","description":"Underwood Dudley is well known for his collection of books on mathematical cranks. Here he offers yet another - angle trisectors. It is impossible to trisect angles with straightedge and compass alone, but many people try and think they have succeeded. This book is about angle trisections and the people who attempt them. According to Dudley: 'Hardly any mathematical training is necessary to read this book. There is a little trigonometry here and there, but it may be safely skipped. There are hardly any equations. There are no exercises and there will be no final examination. The worst victim of mathematics anxiety can read this book with profit and dry palms. It is quite suitable to give as a present.'","brand":"WoB","offers":[{"title":"US \/ GOOD \/ SBYB","offer_id":50366788829457,"sku":"CIN0883855143G","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0883855143.jpg?v=1763473313"},{"product_id":"is-mathematics-inevitable-book-underwood-dudley-9780883855669","title":"Is Mathematics Inevitable?","description":"This is a collection of gems from the literature of mathematics that shine as brightly today as when they first appeared in print. They deserve to be seen and admired. The selections include two opposing views on the purpose of mathematics, The Strong Law of Small Numbers, the treatment of calculus in the 1771 Encyclopaedia Britannica, several proofs that the number of legs on a horse is infinite, a deserved refutation of the ridiculous Euler-Diderot anecdote, the real story of pi and the Indiana Legislature, the reason why Theodorus stopped proving that square roots were irrational when he got to the square root of 17, an excerpt from Mathematics Made Difficult; a glimpse into the mind of a calculating prodigy.  There will be something of interest here for almost anyone interested in mathematics. Underwood Dudley is the bestselling author of several MAA books: Mathematical Cranks, Numerology, and the Trisectors.

It is a descendent of number mysticism, the belief the contemplation of numbers can give mystical and non-rational insights into life, the universe and everything. 2500 years ago, Pythagoras originated number mysticism, crediting certain numbers with characteristics, through numerology, is a more recent invention that allots numbers, hence characteristics, to individuals. Underwood Dudley outlines here the history of number mysticism and numerology and gives many examples, including biorhythyms, Bible-numberists, pyramidologists and a plethora of others. His message is that numbers do indeed have power, but over minds not events. This is the only book that exposes this particular human folly, and requires no mathematical background beyond knowledge of numbers.","brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":50486339666193,"sku":"","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":50486340157713,"sku":"GOR011109193","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ WELL_READ \/ SBYB","offer_id":51521090388241,"sku":"CIN0883855240A","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0883855240.jpg?v=1751171561"},{"product_id":"budget-of-trisections-book-underwood-dudley-9780387965680","title":"A Budget of Trisections","description":"It is impossible to trisect angles with straightedge and compass alone, but many people try and think they have succeeded.

Number theory has an impressive history, which this guide investigates. Rather than being a textbook with exercises and solutions, this guide is an exploration of this interesting and exciting field. Its important results are all included, usually with accompanying proofs: the Quadratic Reciprocity Theorem is proved as Gauss did it. The material has been chosen to be maximally broad whilst remaining concise and accessible.","brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":51903022235921,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":51903022465297,"sku":"GOR014454552","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9780883853474.jpg?v=1755076523"},{"product_id":"budget-of-trisections-book-underwood-dudley-9781461264309","title":"A Budget of Trisections","description":"It is impossible to trisect angles with straightedge and compass alone, but many people try and think they have succeeded.

So weisen Numerologen und Zahlenmystiker den Zahlen eine aussergewohnliche Macht uber Ereignisse zu. Ein Pyramidologe zum Beispiel vermisst seine Pyramide und schliet aus den Zahlen, dass die Welt am 20. August 1953 untergeht. Die Borsenkurse schwanken auf und ab, weil die Fibonaccizahlen sie dazu bringen, die Bibel ist voller Siebener und Dreizehner, weil Gott es so gewollt hat, und Biorhythmiker behaupten, die Menschen oszillieren in Zyklen von 23, 28 und 33 Tagen, und folglich sei unser Verhalten von diesen Ziffern bestimmt. Es findet sich kaum ein Bereich, auf den nicht irgendwelche Zahlen angeblich Einfluss haben. Underwood Dudley hat sich ihren Geheimsinn naher angesehen und begleitet in seinem unterhaltsam zu lesendem Buch den Leser auf eine historische Tour durch die Numerologie. Angefangen mit Pythagoras, uber die Neupythagoraer, die Pyramidologen, die biblischen und Shakespeares Zahlen, wird der Bogen bis hin zu modernen Zahlenmystikern gespannt, die eine geheimnisvolle Zahlenfolge etwa auch im UPC-Strichcode zu finden glauben. Dabei lasst Dudley den Leser nicht im Zweifel, wie die Mathematik die Numerologie sieht: Diesen Aberglauben mit den Mitteln der Vernunft zu bekampfen, ist fur sie und den Autor die vordringlichste Aufgabe.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52454902661393,"sku":"NLS9783034850872","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ NEW \/ INGRAM","offer_id":52760648876305,"sku":"NIN9783034850872","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783034850872.jpg?v=1759372604"},{"product_id":"mathematik-zwischen-wahn-und-witz-book-underwood-dudley-9783764351458","title":"Mathematik zwischen Wahn und Witz","description":null,"brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":52663686496529,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ INGRAM","offer_id":52663687282961,"sku":"NLS9783764351458","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783764351458.jpg?v=1762272646"},{"product_id":"elementary-number-theory-book-underwood-dudley-9780716700760","title":"Elementary Number Theory","description":"Ideal for a first course in number theory, this lively, engaging text requires only a familiarity with elementary algebra and the properties of real numbers. Author Underwood Dudley, who has written a series of popular mathematics books, maintains that the best way to learn mathematics is by solving problems. In keeping with this philosophy, the text includes nearly 1,000 exercises and problems some computational and some classical, many original, and some with complete solutions.\u003cbr\u003eThe opening chapters offer sound explanations of the basics of elementary number theory anddevelop the fundamental properties of integers and congruences. Subsequent chapters present proofs of Fermat's and Wilson's theorems, introduce number theoretic functions, and explore the quadratic reciprocity theorem. Three independent sections follow, with examinations of the representation of numbers, diophantine equations, and primes. The text concludes with 260 additional problems, three helpful appendixes, and answers to selected exercises and problems.","brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":52862811111697,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ GOOD \/ SBYB","offer_id":52862811275537,"sku":"CIN071670076XG","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9780716700760.jpg?v=1765204772"}],"url":"https:\/\/www.worldofbooks.com\/en-gb\/collections\/author-books-by-underwood-dudley.oembed","provider":"World of Books ","version":"1.0","type":"link"}
