...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)

A Helping of Friday Potpourri

A compendium of mathy links you might want to check out over the weekend, if you've missed….

1) A "fiendish" set of brain teasers here:


2) If you missed this CBS News clip on math teacher Jim O'Connor, well, stop whatever you're doing and watch it (…and have a kleenex ready):

3) A creative approach to trigonometry here (from the BetterExplained site):


4) Interestingly, just weeks after a Kazakh mathematician claimed a proof (still being studied) of Navier-Stokes equations, none-other than Terry Tao has offered a new approach to the problem:


5) I won't pretend to understand all this digital currency stuff… but that doesn't stop me from finding it fascinating... enter "Riecoin": http://tinyurl.com/kgjg7q4

6) just some fractal fun, Sierpinski style: http://beautyandthemaths.tumblr.com/post/77265096812

...as always, a lot of math education ideas bouncing around the mathosphere, including:

7) another Top 10 issues in math education, this time from Brie Finegold:

8) more on the troubles in math education here, via Slate:  http://tinyurl.com/kfbkedf

9) Meanwhile, Arizona is dumping Common Core; read all about it in these 2 places:

http://www.goodmath.org/blog/?p=2882  (from Mark Chu-Carroll)

http://tinyurl.com/kky7z46  (AZ. newspaper)

10) And Alex Bellos gets schooled on current math education in Britain in this 1/2 hr. podcast:
http://www.bbc.co.uk/programmes/b03szv89 , and I already linked (over at Math-Frolic) to this Conrad Wolfram piece on reforming British math education: http://tinyurl.com/kyp8yto

11) Lastly, not math, but still an interesting post, on who gets hired by Google... where "expertise," even a college degree, is not so important, but here's what is:  http://tinyurl.com/lxny6g9

-- Sunday, or Monday at latest, I should have another interview up here with another cyber math enthusiast, meanwhile enjoy some of the above links… and, your weekend! (and let me know ASAP of any broken links)
