...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 Math Mix


Bits of math from the week:

1)  Braess's Paradox from Brian Hayes and American Scientist:
http://www.americanscientist.org/issues/pub/2015/4/playing-in-traffic

2)  If you haven't already read Jim Henle's "The Proof and the Pudding," this piece by Jim may spur you to do so:
https://theconversation.com/mathematics-spaghetti-alla-carbonara-and-you-42650

3)  Evelyn Lamb on "Cantor's Leaky Tent" (yeah, I'd never heard of it either):
http://blogs.scientificamerican.com/roots-of-unity/a-few-of-my-favorite-spaces-cantor-s-leaky-tent/

4)  You should be listening to Krista Tippett's "On Being" NPR radio show each week, but if not, last week she re-ran an episode with astronomer/author Mario Livio:
http://onbeing.org/program/mario-livio-mysteries-of-an-expanding-universe/244

5)  What would a weekly linkfest be without an entry for Jordan Ellenberg... this time on the wonderful Slate Money Podcast of all places! (which includes Mathbabe, Cathy O'Neil):

6)  Michael Pershan with a post on "recursive" versus "relational" thinking:
http://mathmistakes.org/recursive-and-relational-thinking-and-the-feedback-each-deserves/

7)  If you're into complexity and P vs. NP then this Motherboard piece (on "edit distance") is probably also of interest:

8) 
Keith Devlin was among several guests on the Diane Rehm Show this week discussing digital games and education:

9) 
Ben Orlin striking my funny bone:

10)  And just linking to this as a public service announcement (scam conferences):
https://xianblog.wordpress.com/2015/06/24/whazzat-scam-conferences-inc/

11)  More problems with Common Core, statistics, and specifically, EngageNY:
http://youdothemathkthrucalculus.blogspot.com/2015/06/problems-with-common-core-and-engageny.html

12)  Ok, straying a bit farther afield from mathematics, Scott Aaronson speculates on what quantum computing may tell us about quantum mechanics:
http://www.pbs.org/wgbh/nova/blogs/physics/?p=2204

13)  And on a more mystical note, one ought not miss George Johnson's NY Times' essay on "Humankind's Existentially Lucky Numbers":

Have a great weekend and come back here on Monday when I'll be chatting with Siobhan Roberts (well, chatting via cyberspace that is: Math-Frolic Interview #33). If you don't already know who Siobhan is, I think you'll be seeing her name a lot in coming months.

Potpourri BONUS! (extra NON-mathematical links of interest):

1)  From last week's TEDRadioHour, Sean Carroll attempts to explain "why does time exist at all":
http://www.npr.org/2015/06/19/415003106/why-does-time-exist

2)  More philosophy than math, nice Aeon piece on the nature of causality (if it even exists):
