...a companion blog to "Math-Frolic," specifically for interviews, book reviews, weekly-linkfests, and longer posts or commentary than usually found at the Math-Frolic site.

"Mathematics, rightly viewed, possesses not only truth, but supreme beauty – a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show." ---Bertrand Russell (1907) Rob Gluck

"I have come to believe, though very reluctantly, that it [mathematics] consists of tautologies. I fear that, to a mind of sufficient intellectual power, the whole of mathematics would appear trivial, as trivial as the statement that a four-legged animal is an animal." ---Bertrand Russell (1957)

Friday Potpourri

Another week's mix of mathy selections:

1)  Evelyn Lamb reviews "Really Big Numbers" by Richard Schwartz (children's book):

2)  You undoubtedly heard this week of Facebook's mass study in emotion-manipulation; be sure you've read Jordan Ellenberg's take:
And several more links re: the Facebook study here:

3)  A little introduction to the quaternions:

4)  Another teacher weighs in on the new volume, "Playing With Math," from Sue VanHattum:

5)  Doing calculus employing masses instead of area:

6)  Statistics as an underpinning of science and society:
But then, this non-confidence-instilling piece on confidence intervals:

7)  I blog-posted this one but it's so much fun I'll re-link to the "Painter's Paradox" of Gabriel's Horn, in case you missed it:

8) Look Ma, no numbers!... a pictorial geomagic square from the ever-inventive Lee Sallows (via Futility Closet):

9) Anyone know if a P vs. NP proof that appeared this week is being taken seriously??? I'm certainly in no position to judge, though just the fact that it concludes that P = NP, and does so in essentially just 3 pages, gives me cause for doubt:

10) And just up from Sol Lederman another new "Inspired By Math" podcast, with Richard Rusczyk and a focus on math competitions:

11)  Lastly, my own take on Alex Bellos' latest book, "The Grapes of Math":

  1. Seriousness is no friend of intelligence. not for everyone, things are difficult, some are so easy to like a game. eg http://en.wikipedia.org/wiki/William_James_Sidis
