Alexander Bogomolny …cutting the knot


No doubt many are familiar with Terry Gross’s “Fresh Air” long-running show on NPR… so long running in fact that whenever someone famous dies, it turns out they are likely to have been interviewed on Fresh Air at some point, and NPR, in tribute, re-runs the episode.

This week my interview with Alexander Bogomolny, done 4+ years ago, abruptly spiked up significantly in weekly traffic, associated with his recent passing.

I’ve always wanted my simple interviews to be ongoing sources of additional information about the math communicators highlighted, but it only just suddenly hit me (not to be too morbid about it) that all these folks will pass on at some point, and the interviews also stand a bit as tributes that readers may draw some reminiscences from. Just a little odd/ironic to realize that these posts may accrue as many or more visits upon the death of an individual as when they were living.
Most of these interviewees will outlive me (at least I’m older than the majority of them), but in some cases at least, I s’pose that like Terry Gross, I may still be around to recall the blog time spent with one or more of these math communicators when they pass. Anyway, be sure to fully appreciate them while they're among us!

I'll end by passing along just one of the countless puzzles that Alexander posted (with 4 solutions as he would often do). It is the same 'lost plane-boarding pass' puzzle that Zoe Griffiths recently employed in the Big Internet Math-Off to win her first round:

Bogomolny's Insights...


One of the most expansive, fun, brimming math websites on the internet is Russian-born Alexander Bogomolny's "CTK Insights" or related "Cut the Knot" site. A recent interview with Alexander here:

http://mathblogging.wordpress.com/2013/02/15/alexander-bogomolny/

He explains where the name of the site comes from, and has interesting things to say about math education in the U.S. as well (some of which reflects thoughts I put forth in my latest, longish MathTango post).

On a side-note, I just recently discovered that Bogomolny also has a nice page (with lots of links) devoted to one of my favorite topics, "self-reference" -- I discovered this while I was researching a classic problematic (self-contradictory) sentence: "Their are three misteaks in this sentence" (...think about it):
