Happy Birthday Neil Sloane and OEIS!

Wonderful Alex Bellos piece in The Guardian today, on Neil Sloane and the OEIS (Online Encyclopedia of Integer Sequences) he founded. Fascinating reading:

I was happy to learn of the Kolakoski sequence which combines a number sequence with self-reference (one of my favorite topics), and of which Bellos writes, "Mathematicians drool over this sequence."
 The OEIS has been around as a go-to resource for mathematicians of all stripes for 50 years now, and today includes some 250,000 number sequences, while still growing, according to the article, at a rate of about 40 new sequences each day! Some sequences can be quite creative of course, and open up interesting, difficult-to-solve questions.
Rutgers' Doron Zeilberger goes so far as to say that the OEIS has made Sloane the world's most influential mathematician!
Lots more in the article, including a video.
