Libro del mes: Como Mentir com a Estatística

StatiLibro del mes de abril es Cómo mentir con estadísticas de Darrell Huff.

Lo que estas páginas, escritas con ingenio y humor, nos ofrecen es, en realidad, un curso de sentido común para aprender a descubrir los ardides con los que cada día pretenden engañarnos, manipulando cifras y gráficas, los medios de comunicación, los políticos, la publicidad… Lo que aquí se nos cuenta resulta divertido; pero es bueno tomarlo en serio, porque, como nos dice el autor, “los desaprensivos ya conocen estos trucos; los hombres honrados deben aprenderlos en defensa propia”. –> link

How To Lie With Statistics

StatiApril’s Book of the Month is How To Lie With Statistics by Darrell Huff. Norton reissued this 1954 book in 1993, and this edition is available on Kindle. There is a 1991 Penguin edition and it has been translated into many languages.

This book may be over 60 years old, (and therefore the examples are dated), and statistics has certainly moved on since it was first published, but the volume remains a best-seller and is a humorously illustrated light introduction to many key ideas in statistics. It informs us about statistics through showing how statistical analyses can be used to fool and create misunderstanding.

For other translations look here: Indonesian, Thai, Czech, Turkish, Greek

The Exact Sciences in Antiquity

exactSciencesMarch’s Book of the Month is: The Exact Sciences in Antiquity by Otto Neugebauer. Second edition published in 1957 by Brown University Press, now republished by Dover in 1969.

Commentary adapted from the Amazon website, see this link for further information: Based on a series of lectures to non-experts 1949, this is the standard non-technical coverage of Egyptian and Babylonian mathematics and astronomy. It reveals that the Babylonian strength in algebraic and numerical work is comparable to the mathematics of the early Renaissance in Europe. In the realm of astronomy, it describes a sophistication which is interpreted less as the result of millennia of observations (as used to be the interpretation) than as a competent mathematical system. An Appendix discusses certain aspects of Greek astronomy and the indebtedness of the Copernican system to Ptolemaic and Islamic methods.

CultureMATH est un site dédié à la formation des professeurs de mathématiques du secondaire. Les articles publiés présentent des notions mathématiques du programme scolaire dans l’objectif de les revisiter, de les présenter d’une manière plus approfondie. D’autres ressources sont diposnibles : des expériences pédagogiques, des exemples de résolution de problèmes (afin de présenter la diversité des procédures), et les questions du jeudi (énigmes).

CultureMATH

culturMATHMarch’s Site of the Month is: CultureMATH

CultureMATH is a French language website dedicated to secondary mathematics teacher education. Published articles present mathematical ideas at several levels. The topics are often related to the curriculum, to present them more deeply. Other resources are also available: some pedagogical experiences, examples of problem solving (in order to present the diversity of procedures), and a series of puzzles.

Mathematical Etudes

01_301_2February’s Site of the Month: Mathematical Etudes

This is a Russian site, but has an English and a French version, use “en” or “fr” at the end of the URL.

The site contains several 3D animated films that illustrate theorems or ideas in mathematics, and much more. For example, in the Apps for iPhones there are 90 cryptarithms which are available in English, French, German, Italian, Russian, and Spanish.

The Story of a Number

storyofanumberFebruary’s Book of the Month is: The Story of a Number by Eli Manor. First published in 1993 and available in paperback in the Princeton Science Library.

From the “Goodreads” website. See here for more details.
“…. Geared to the reader with only a modest background in mathematics, the book describes the story of e from a human as well as a mathematical perspective. In a sense, it is the story of an entire period in the history of mathematics, from the early seventeenth to the late nineteenth century, with the invention of calculus at its center. Many of the players who took part in this story are here brought to life. …. The unifying theme throughout the book is the idea that a single number can tie together so many different aspects of mathematics …. The book ends with an account of the discovery of transcendental numbers ….”

The Largest Known Primes

BigPrimeBigJanuary’s Site of the Month: The Largest Known Primes – A Summary

In January a new largest prime was found – with over 22 million digits. Cooper, Woltman, Kurowski and Blosser used GIMPS (Great Internet Mersenne Prime Search) which is software that, since 1996, has generated many new primes.
This web page describes these, and other, types of large primes, links to further information, and discusses Euclid’s proof of the infinitude of primes

Handel in der Stadt

Die Autoren des Originaltextes sind Alberto A. Pintoa (Universität Porto, cLIAAD-INESC Porto LA) und Telmo Parreira (Universität Minho, cLIAAD-INESC Porto LA).

Warst du je frustriert von dem Mangel an Auswahl, wenn du etwas kaufen gehst? Warum neigen die Produzenten dazu ihre Produkte so ähnlich wie möglich zueinander zu gestalten? Wenn wir modellieren wie Käufer in einer Stadt entscheiden, in welchem Geschäft sie ihre Einkäufe tätigen, führt uns die resultierende Mathematik zum Gesetz von Hotelling. Dieses besagt, dass die Gestaltung eines Produkts ähnlich zum Konkurrenten tatsächlich eine rationale Entscheidung ist. Wir werden ebenso in die Mathematik der Spieltheorie und des Nash-Gleichgewichts geführt.

الرياضيات للملايين

Lancelot Hogbenالكتاب المتميّز لشهر يناير 2016 : “الرياضيات للملايين: كيفية السيطرة على سحر الأعداد”
Mathematics for the Million

المؤلف : لنسلوت هوگبن Lancelot Hogben
الطبعة الأولى 1936، ثم أعيد طبعه عدة مرات.
من المقدمة: “إن الطريقة المعتادة لتأليف كتاب حول الرياضيات هي إظهار كيف تَتْبع كلُّ خطوة -بصفة منطقية- خطوةً أخرى وردت قبلها دون إعلامك باستعمالها وكيفيته مستقبلا. وُضع هذا الكتاب ليبيّن لك كيف تَتْبع كلُّ خطوة –تاريخيا- خطوةً جاءت قبلها مشيرا إلى استخداماتها سواء بالنسبة لك إذا ما أخذت بها أو لغيرك. الطريقة الأولى تُنفّر الكثير من الناس الأذكياء والأحياء اجتماعيا لأن الأذكياء يحْذَرون من المنطق المحض، والناس الأحياء اجتماعيا يعتبرون الدماغ البشري كأداة للنشاط الاجتماعي”

الفصول :
الرياضيات في العصور الغابرة
القواعد اللغوية للحجم والترتيب والشكل
إقليدس كنقطة انطلاق
المعارف بالعدد في العصور القديمة
بروز وانحطاط الثقافة الإسكندرانية
فجر لا شيء
رياضيات البحّار
هندسة الحركة
اللوغاريتمات والبحث في السلاسل
حساب التفاضل والتكامل عند نيوتن Newton وليببنيتز Leibnitz
جبر رقعة الشطرنج
جبر الاختيار والحظ
