NOTE: This will be the last ‘Friday potpourri’ or post at MathTango. With the country in seriously deep-doo-doo I'd rather free up some collusion time to work on expunging orange-puppets or others who find 1930s Germany peculiarly appealing (…also, got some reading to catch up on ;).

Wasn’t sure if I would or wouldn’t compile a potpourri this week, but in the end (and with NO collusion, mind you, NONE, noooo collusion whatsoever) here it is:
1) “The biggest skill to learn moving forward…” (h/t Gary Davis):

Just continuing my earlier Round 1, off-the-cuff analysis of the Big Internet Math-Off competition, now that Round 2 is near closing...
Have been quite surprised by several of the outcomes thus far in the contest, either by who won, or by the margin of victory. A recent such surprising match was Edmund Harriss vs. Paul Taylor, with the former choosing to write about the Collatz conjecture "Shecky Riemann"http://www.blogger.com/profile/07065658607024191185noreply@blogger.com0tag:blogger.com,1999:blog-2360342670847209341.post-34335142903384562252018-07-13T08:00:00.000-04:002018-07-13T08:00:11.409-04:00Friday the 13th
hot air, anyone?
Been so busy this week watching Britain and U.S. race to see who can disintegrate first, that I didn’t have much time left over for compiling math bits, but here’s a few:
1) New Alex Bellos puzzle book now available in U.S.:

2) Null and alternative hypotheses:

While the Donald was spit-shining his jackboots this week, I hosed off my Crocs and compiled another potpourri:
1) Interview with philosopher Clark Glymour on probability, causality, science, free will (h/t Sean Carroll):

"Ronald Coase cynically observed that, 'If you torture the data long enough, it will confess.' Standard Deviations is an exploration of dozens of examples of tortuous assertions that, with even a moment's reflection, don't pass the smell test. Sometimes, the unscrupulous deliberately try to mislead us. Other times, the well-intentioned are blissfully unaware of the "Shecky Riemann"http://www.blogger.com/profile/07065658607024191185noreply@blogger.com0tag:blogger.com,1999:blog-2360342670847209341.post-8775704925438336672018-06-08T08:00:00.000-04:002018-06-08T08:00:05.463-04:00Mathy Things You May Have Missed
After pardoning myself for all the things I’ve said, or will in the future say (or think or whisper) about our dysfunctional (to put it kindly) President, I proceeded to compile another weekly math potpourri:
1) Eli Maor on math & music:

2) Fermat primes and almost Fermat primes:

My favorite form of writing (to read) is the essay. Books on single themes, no matter how well-written, invariably lapse into sections or passages that are redundant, plodding, or pedantic. The essay form is brief enough to be rich and scintillating from beginning to end, in the hands of a good craftsman.
All this to say, that even though it’s only June I think I have already found my "Shecky Riemann"http://www.blogger.com/profile/07065658607024191185noreply@blogger.com0tag:blogger.com,1999:blog-2360342670847209341.post-78448118626047568252018-06-01T08:00:00.000-04:002018-06-01T08:00:00.134-04:00New Month, New Potpourri
Just for a change this week I won’t open with any insults whatsoever of our Knuckledragger-and-Chief pseudo-leader… but simply go straight to the latest Friday potpourri:
1) YOU too can take a Harvard “Introduction to Probability” course:

Maybe this week’s viral Laurel/Yanny episode can finally help explain how it is that some people listening to a certain Donald hear a purported President speak, while others more correctly hear a venal Demagogue blathering.
...In any event, a new Friday potpourri:
1) Michael Harris, interesting as always, on the uses and responsibilities of mathematics:

To slightly streamline my own blogging time am making a few changes to the 'Friday Potpourri' that perhaps readers ought be apprised of (way back I originally conceived of the potpourri as a compendium of slightly off-the-beaten-track math bits, and ever since reading/enjoying David Wells’ quirky “Book of Curious and Interesting Mathematics” have thought of attempting more of that):

Friday may be money-laundering day at the White House, but at MathTango it’s math-potpourri day.
(…when I can find time I’ll explain a few changes I’m making to the Friday potpourri):
1) Possibly a good thread for teachers to contemplate:

2) Somewhat related, a few, brief teaching “meta-lessons” from Kalid Azad:

I attended (long enough ago that a 50-year reunion is coming up!) a private secondary school where the phrase “in loco parentis” was oft-discussed.

Am trying something ever-so-slightly different this week and next, for the potpourri (you may well notice no difference), and will explain later, if I decide to make the change permanent.
In any event, with or without any changes, you have assurances from my personal physician Vinnie Boom-Bornstein, that this blog will continue to be “astonishingly excellent,” and he also notes that at a slim "Shecky Riemann"http://www.blogger.com/profile/07065658607024191185noreply@blogger.com0tag:blogger.com,1999:blog-2360342670847209341.post-8473122426648272312018-04-27T08:00:00.000-04:002018-04-27T13:18:19.547-04:00Potpourri Again...

1) 5 book recommendations for philosophy of mathematics:

2) A little math history (of the “when-will-I-ever-use-this” form) about Huygens and Leibniz (h/t Evelyn Lamb):

A book blurb today. Usually I’ve heard/read some buzz about books I receive review copies of in the mail, and then have built-in expectations. Occasionally though a volume shows up I’ve heard nothing about, nor even seen the authors names before. “Weird Math” arrived recently as such a book. The authors, David Darling and Agnijo Banerjee are a science writer and math prodigy pair bringing forth"Shecky Riemann"http://www.blogger.com/profile/07065658607024191185noreply@blogger.com0tag:blogger.com,1999:blog-2360342670847209341.post-50550135686649421512018-04-06T08:00:00.000-04:002018-04-06T08:00:30.609-04:00Soooo Much Winning...
While our Aryan President was busy (in-between rounds of golf) consulting with his ass-kissing, rubber-stamping sycophants, er I mean, staff, I toiled alone authoring another weekly math potpourri:
