I collected these, so you wouldn't have to ;-):

**1)**"

*Reflections on Paul Erdös*" from AMS in this his centenary year:

**http://www.ams.org/notices/201502/rnoti-p121.pdf**

**2)**A film made based on the Twin Prime conjecture work of Subway sandwich maker, and mathematician ;-) Yitang Zhang:

also, another wonderful popular press piece (from the

**New Yorker**) on the 59-year-old, sudden-celebrity Dr. Zhang and his work here:

**3)**Still another commentary on the roiling that has followed Mochizuki's claimed ABC conjecture proof:

...and Mark Chu-Carroll attempts to explain the ABC conjecture to the rest of us... before concluding that "

*...mathematicians are crazy people!*" ;-):

**4)**Here's some fun with "deflategate," if you followed the sports story of the New England Patriots' deflated balls ;-):

**5)**Need an introductory post on Cantor and infinity for some young person? Nice, longish one here (gets heavier as it goes along), including several videos:

**6)**A really fun read, newly-posted at

**AMS blogs**, from Evelyn Lamb, on some different aspects of 'sucking at math' (with links to A.K. Whitney's writings on "

*Mathochism*" over at

**Medium**that I need to further check out):

**7)**A couple of tweeted lines this week from Steven Strogatz (who is doing one flipped classroom this term) that just seem worth repeating:

"

*"*

**The students are so alive and engaged in my flipped class (nonlinear dynamics & chaos).**"

*"*

**My other class this term is not flipped. Feels flat, almost inhumane...****8)**And an article on math educator Jo Boaler here:

http://news.stanford.edu/news/2015/january/math-learning-boaler-012915.html

**9)**The increasing tension between U.S. mathematicians and the NSA gets some new coverage from

**Science**Magazine:

**http://www.sciencemag.org/content/347/6221/495.full.pdf**

**10)**Meanwhile, for your funnybone,

**SolveMyMaths**posted some Dave Gorman comedy about perfect, friendly, and sociable numbers:

**11)**As always,

...NEW feature! (potpourri bonus): Last week's grab-bag ended with a side-note, recommending David Pogue's new "

**Pogue's Basics**" book. I may now try to incorporate a "

**potpourri BONUS**" each week, pointing to 1 or 2

**-math links I simply found especially interesting during the week. Here are this week's selections:**

__non__**a)**One of the most jaw-dropping science stories I've heard (out of

*SO MANY*from

**NPR**), about blindness, echolocation, expectations (the story of Daniel Kish)... an hour-long episode; if you haven't heard it try to make time for it and see if you find it as flabbergasting as I did:

http://www.npr.org/programs/invisibilia/378577902/how-to-become-batman

**b)**...I could probably fill these "bonuses" with just

**NPR**programs!! Anyway, the 2nd selection is the first (21-min.) segment from last week's "

*" -- perhaps the most phenomenal (almost bizarre) story I've ever heard of a misogynist internet troll experiencing a change-of-heart:*
