[37][wp37] is prime, and also _sexy_ prime. It has the interesting property of
being the number most likely offered when you ask someone to pick a number
between 1 and 100[^1]. Thirty seven is neat!

Eta Boötes, 37 lightyears away, is now in my [light cone][lightcone]. [NGC
2169][ngc2169] is an open star cluster in Orion that looks remarkably like the
number 37.
