Friday Potpourri

 A smallish bowl of math ghoulash from this week:

1)  Ed Frenkel's recent public talk at Oxford (GOOD stuff):

2)  The Fourier Transform (from The Guardian):

3)  Another interesting (in a nerve-wracking way) puzzle from Presh Talwalkar (Zeckhauser’s Paradox):   http://ow.ly/z7Jx2

4)  John Allen Paulos talks attraction, statistics, and Bayes Theorem in the NY Times:

5)  Vi Hart, being her cool self again (when she's not doing microwave countdowns!), takes a look at reverse Cantor diagonalization -- now if she could just add a 1/2 speed button to her vids ;-):

6) Mike Lawler and the boys teach some combinatorics:

7) These two links just showing up in my Twitter feed (h/t to Alex Bogomolny and Gary Davis) on Bill Gates and Common Core (good reads):

8)  And it was a hugely oddball week over at Math-Frolic with talk of Richard Feynman, Sally Ride, Comcast, but little math. Maybe back-to-normal next week...


--- It feels impossible to even put up a blog post today, without acknowledging the horrific news of yesterday, a very dark day. Sympathies (...despite what little potency they have) to any/all directly affected by the tragedies... NOT proud to be part of the human race today. 
A peaceful, contemplative weekend to all... somehow.

ADDENDUM: now have to add this ;-) just appearing in my Twitter feed (h/t Sam Knight):
