Lotsa leftovers that didn't make it into

*this week (probably be even more today, but this list is already long enough):*

**Math-Frolic****1)**A "near-miss" in mathematics (a constructed polyhedron that doesn't exist; h/t Patrick Honner):

http://isohedral.ca/a-new-near-miss/

**2)**Andrew Gelman, pessimistically,

*on the*

*'too big to fail*' problem of journal retractions:

http://andrewgelman.com/2016/02/22/its-too-hard-to-publish-criticisms-and-obtain-data-for-replication/

Near the end he writes:"

*So unfortunately I don’t think it’s possible. Reform would be great, post-publication review is great, but I think we just have to give up on retraction. The system is just too big to fail.*" And he compares previously published work as "

*potentially a junk bond supported by toxic loans and you shouldn’t rely on it*."

**3)**This week,

**Quanta Magazine**(in a tweet) passed along a link to these animated math videos:

**4)**Maria Popova (of "

*") paying tribute to mathematics this week:*

**Brainpickings**https://www.brainpickings.org/2016/02/22/james-joseph-sylvester-mathematics-address/

**5)**Dave Finkel

**TEDTalk**video (recommended by James Tanton) on math education:

**6)**Probability and coincidences in the popular press (interesting

**Atlantic**piece):

http://www.theatlantic.com/science/archive/2016/02/the-true-meaning-of-coincidences/463164/

**7)**Andrew Gelman again, this time looking at some statistics in the press being mangled (I'm shocked, SHOCKED I tell you!) re: Valentine's Day spending:

**8)**A little update on Zipf's Law:

**9)**Solving the Kadison-Singer problem by bridging disciplines:

http://www.wnyc.org/story/how-outsiders-cracked-50-year-math-mystery/

**10)**Bertrand's Paradox has been written about many times; what I found intriguing in this post though is the very last "

*Final remark*," almost off-handedly mentioning that the author was working on yet another possible solution to the 3 that are usually given:

**11)**h/t to Cathy O'Neil for highlighting this interesting-looking new book of math essays:

**You say you've mastered Rubik's Cube... well, take it a notch up with Sudoku Cube (h/t Cliff Pickover):**

**13)**https://en.wikipedia.org/wiki/Sudoku_Cube

**Samuel Hansen's "Relatively Prime" podcast is seeking funding for a 3rd successful season of mathematical stories (just couple of wks. left on**

**14)***Kickstarter*campaign):

(check it out!)

**Perhaps quantum computing can wait... an NP-complete problem solved using biology!:**

**15)**http://arstechnica.com/science/2016/02/np-complete-problem-solved-with-biological-motors/

**I'll finish out, venturing over to physics again, with Brian Greene explaining gravitational waves to Stephen Colbert (quite good actually):**
