Sequence Man, Neil Sloane

Fascinating new Erica Klarreich piece (interview) in Quanta on Neil Sloane and the OEIS, Online Encyclopedia of Integer Sequences, which is now home to more than a quarter million number sequences contributed by mathematicians the world over:

Turns out that when Neil isn't curating (along with a set of editors) number sequences he's writing guidebooks about rock-climbing in New Jersey! Yet that is one of the less interesting of all the many great tidbits in the article.
[By the way, since my previous post was about math and music, worth noting that all the sequences in the OEIS can (as an option on the site) be put to music and played!]
