Strogatz, Zero, and Probability

Well, it's not with me :-( but nonetheless a nice interview with Steven Strogatz from here (turns out he has a special fondness for the number 1/7, and admits to a prior ignorance of the arithmetic operation of "casting out nines"):

Meanwhile, the various dangers of 0 (psssst... DON'T divide by it) are explained in this recent 13-min. Numberphile video:

And lastly, a nice little counterintuitive probability conundrum from Futility Closet involving bridge hands and aces:

(somewhat reminiscent of the more-famous boy-or-girl paradox or even the "boy born on Tuesday problem")
