Metamagical Themas

matemagicalMay’s Book of the Month is Metamagical Themas by Douglas Hofstadter. First published in 1985 by Basic Books, available in hardback and paperback. Also available in French under the title Ma Thémagie (InterEditions, 1988).

Our second ever Book of the Month was Martin Gardner’s Mathematical Puzzles and Diversions — that author’s collected columns from Scientific American. Hofstadter followed Gardner writing this column, and the current month’s book is also a collection of those columns. Hofstadter also wrote Gödel, Escher, Bach which is another featured Book of the Month.

TEDEd Lessons Worth Sharing

TEDEd2April’s Site of the Month is: TEDEd Lessons Worth Sharing

TEDEd Lessons are short (~4mins) video clips, and the ones on mathematics include several riddles, plus unusual uses of mathematics. There are also some conventional clips such as “The Secrets of Pascals Triangle” (which does acknowledge prior appearances in other cultures) and “The Complex Geometry of Islamic Design”. If you have an idea for a mathematical TEDEd Lesson then you can get assistance making the animated video.

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.

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.

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

Mathematics for the Million

Lancelot HogbenJanuary’s Book of the Month is Mathematics for the Million: How to Master the Magic of Numbers by Lancelot Hogben. First published in 1936 and reprinted many times.

From the Prologue: “The customary way of writing a book about mathematics is show how each step follows logically from the one before without telling you what use there will be in taking it. This book is written to show you how each step follows historically from the step before and what use it will be to you or someone else if it is taken. The first method repels many people who are intelligent and socially alive, because intelligent people are suspicious of mere logic, and people who are socially alive regard the human brain as an instrument for social activity”

Historical Topics for the Mathematics Classroom

MathClassroomDecember’s Book of the Month is Historical Topics for the Mathematics Classroom by J.K. Baumgart, D.E. Deal, B.R. Vogeli, A.E. Hallerberg, eds., published by the National Council of Teachers of Mathematics.

This book has a summary of the history of each major branch of mathematics (Number, Computation, Algebra, Geometry, Trigonometry and Calculus) followed by brief essays on specific topics of significance within each branch. The last two chapters of the book give a brief, integrated view of the direction of mathematics development over the last century.
Originally published in 1969, and updated in 1989, the book continues to offer high school and university teachers an excellent tool for their own development.
(Adapted from a review by Tim Keenan).
