Week #25 of America’s Trumpian nightmare, but at least there's some wonderful math to distract us (including some more pieces I noted over at Math-Frolic yesterday):
1) Another ‘math-is-beautiful’ article, starting off with Maryam Mirzakhani (h/t Keith Devlin):

2) Neurons use linear algebra to recognize faces:

Week #23 of the hijacking of America…
…sorry, a short potpourri this week, as I’ve had too much summer busy-ness this week, while also remaining glued to the Yingying Zhang case in Illinois, where the accused has now been imprisoned, not in Champaign-Urbana, but in my own original hometown of Decatur!
1) Plenty more math to read in latest “Math Teachers At Play” blog:

Seeing Masterpieces In MathematicsMath-Frolic Interview #42
“I fear that too many people’s mathematics education is devoid of joy. Imagine if children’s reading education focused primarily on spelling and punctuation, but not on delights such as Harry Potter or creating stories of one’s own; that approach would hardly instill students with a love of literature.”
-- Ed Scheinerman

Newly showing up in bookstores, “Unsolved” by Craig Bauer will likely appeal to a wide audience — didn’t ALL of us math-lovers at some time play with cryptograms as a kid… and many carried that interest into adulthood. And even many others, without a direct interest in math, carry a fascination with the mystery, game-playing, and intrigue of ciphers.

“A fascinating insight into the thought processes of someone with little interest in fame, who has mostly stayed under the radar, but who has followed his inquisitive mind wherever it has led him, and reaped the resulting rewards. There is nothing more important than knowing how to think clearly. Read this book and learn from a master.” — Paul Wilmott

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.

“Finding Fibonacci” by Keith Devlin
“Beyond Infinity” by Eugenia Cheng
“The Mathematics Lover’s Companion” by Edward Scheinerman
