First, some New Years resolutions (you know, just in case, stating them publicly makes sticking to them any more likely ;):
1) More exercise and fiber, less sugar, sodium, & carbs
2) More pickleball, birding, hiking, music, flossing (just kidding)
3) #Resist, resist, resist

Good-bye (riddance) to 2016, but not before pointing to a few more math reads:

Math just keeps coming:
1) Jim Propp’s latest monthly offering is on David Kelly’s “Hampshire College Summer Studies in Mathematics” program. If, like me, you’ve never heard of it (and perhaps even moreso if you have) fascinating stuff, with lots of good links:

2) Sort of a cool (unexpected?) factoid that Colin Wright tweeted out this week:
“Except in exactly one case, the digit sum of the product of twin primes is always 8.”
[The exception, btw, is 3 and 5.]

With holiday shopping underway I should probably go ahead and post an end-of-year book wrap-up. Once again there were a great many popular math volumes put out in 2016, but I read fewer, and was enamored of fewer, than in prior years, so this is a bit more of a mish-mash than previous year-end posts.

What a week!... Some folks warned months ago that Donald Trump would be elected President WHEN the Chicago Cubs won a World Series (meaning, at the time, when Hell froze over!). Anyway, a quick request if anyone cares to take me up on it:
There's been a lot of discussion/criticism of prior polling since the election outcome... often proclaiming the polls surprisingly inaccurate.

Jim Propp will probably do a post on self-referential sentences in the middle of this month. His take should be intriguing (and he's posted self-referential "aptitude" tests before)… Doug Hofstadter and Noam Chomsky are among those who think recursion/self-reference are defining attributes of human thinking and brain operation. Interesting that even discussing 'self-reference' is itself, "Shecky Riemann"http://www.blogger.com/profile/07065658607024191185noreply@blogger.com0tag:blogger.com,1999:blog-2360342670847209341.post-25780857437389442132016-11-04T08:30:00.000-04:002016-11-04T08:30:04.380-04:00Some Remnants From the Week

1) This week The Aperiodical tweeted out that, "A little birdy tells us that Mochizuki's abc conjecture proof will be accepted into a journal "in the next few months". Hope it's not in The Journal of Irreproducible Results ;-)
Seriously, how does a journal even have room for such a proof, or do I assume they print summary and commentary, and give a digital link to the actual paper proof?
