Math-Frolic was distracted by other things this week, so here's some of the mathy things it didn't report on:
1) Intransitive dice provide the basis for a possible Polymath Project:

Oscar Fernandez’s slim “The Calculus of Happiness” is a somewhat quirky popular math entry focusing on using math (very little calculus involved) as an aid to one’s health, wealth, and love life. No doubt some will find the book entertaining and enlightening depending on your interest in these 3 topic areas. And it’s nice to see a book devoted to showing the public how basic math applies "Shecky Riemann"http://www.blogger.com/profile/07065658607024191185noreply@blogger.com0tag:blogger.com,1999:blog-2360342670847209341.post-55462954740486740552017-04-14T08:30:00.000-04:002017-04-14T08:30:05.971-04:00This Friday's Mix

I’d actually enjoy a respite from reading… but popular math books keep showing up! Currently in my reading queue are 3 new volumes, so 3 quick blurbs today on:
“Finding Fibonacci” by Keith Devlin
“Beyond Infinity” by Eugenia Cheng
“The Mathematics Lover’s Companion” by Edward Scheinerman
Regular readers here know I love Keith Devlin’s writing… BUT primarily when he’s "Shecky Riemann"http://www.blogger.com/profile/07065658607024191185noreply@blogger.com0tag:blogger.com,1999:blog-2360342670847209341.post-75822656055638514102017-03-10T08:30:00.000-05:002017-03-10T15:21:25.987-05:00Weekly Wrap-up of Mathy Miscellany
1) A little history... his own history that is... from Keith Devlin:
http://www.huffingtonpost.com/entry/58bb4169e4b0fa65b844b419
…Keith seems to be on a Fibonacci kick. He wrote a volume on the popular Italian medieval mathematician a few years back, and now has a new book out about writing the first book:

"The main message of this series is that there is a lot more to mathematics than formulas and learning by rote -- a lot more than the stringency of proof and the rigor usually associated with mathematics (and held so dear by mathematicians). Mathematics has interpretative sides with endless possibilities, many made manifest by writing in natural language."

"What I hope to convince you of today is that the practice of mathematics cultivates virtues that help people flourish. These virtues serve you well no matter what profession you choose. And the movement towards virtue happens through basic human desires.
