A big juicy helping of potpourri this week:

**1)**Quantum mechanics now violating the pigeonhole principle? It's oft-said that if you think you 'understand' quantum mechanics, then you don't, because it isn't comprehensible; and now this adds to the confusion:

**2)**Long, interesting post from Tim Gowers… math over my head, but still interesting just for the glimpse it gives of how his mind operates:

**3)**I'll give another plug to these folks, who are trying to make a documentary around the topic of networks and Bacon-ErdÃ¶s numbers:

**4)**Vi Hart explains transcendental numbers, the number line… and darts, as only she can:

...and h/t to Evelyn Lamb for pointing out this

**arXiv**contribution from Vi Hart

**(**and

**Henry Segerman) on the symmetry of quaternions:**

**http://arxiv.org/pdf/1404.6596v1.pdf**

(does Vi have other publications/submissions?)

Evelyn's own take on the work, btw, is here (from May):

**http://tinyurl.com/lrfqd6m****5)**A survey is being conducted to study the philosophical intuitions of mathematicians "

*relating to the objects and methodology of mathematics*." If you are a mathematician and can take time to participate please go here (they'd like as large a sample as possible, so feel free to pass on to others also):

**6)**Another teacher reports their experience flipping the classroom (geometry):

**7)**Not for the first time, the argument that we ought drop calculus from high school curricula to make room for computer programming and statistics courses, is made:

**8)**A little bit of Boolean algebra history:

**9)**"

*Why Do Americans Stink At Math?*" …more math education debate from the

**NY Times:**

Meanwhile, in the Common Core debate, a California teacher pleads with parents to come view her classroom, before making up their minds:

**10)**Cliff Pickover's newest offering, coming out in time for Christmas, looks like a pleaser for readers here, "

**The Mathematics Devotional**":

**11)**In honor of the Martin Gardner centennial this year, interviews with Martin Gardner (accessible online); always good stuff:

In case you missed it, you can also visit the little carnival game of Martin Gardner's I offered at

*this week:*

**12)**There's a film based on Alan Turing's life, "

**The Imitation Game**," on the way, and James Grime (for

*) has it covered:*

**13)**A

**Forbes**writer summarizes Keith Devlin's view of the future of math (good overview!):

**14)**honors Bill Thurston's creative math mind in their latest post:

*MathMunch***http://mathmunch.org/2014/07/23/zippergons-high-fashion-and-really-big-numbers/**

**15)**Of airplane crashes and statistics:

**16)**Finally, great new (90-min.) interview from "

**7th Avenue Project**" with Stanford mathematician Persi Diaconis this week (thanks to Noson Yanofsky for passing it along to me):

(includes talk of Steve Martin, magic, James Randi, Ricky Jay, stealing, and oh yeah, a smidgen of math, but really more magic)

In fact what better way to head into the weekend than by re-visiting Steve Martin as "

*The Great Flydini*," an act it turns out Persi, believe-it-or-not, was partially responsible (or to blame) for:
