This Week's Finds at 20

This Week's Finds at 20:

A quiet conversation has been going on about this at the Azimuth thread, but it deserves its own entry. This Week’s Finds recently turned 20.

Jordan Ellenberg had the excellent idea of writing a tribute piece, This Week’s Finds in Number Theory, and encouraged others to do something similar. Valeria de Paiva took up the challenge, with This Week’s Finds in Categorical Logic. And Joachim Kock has just followed up with a wonderful appreciation of This Week’s Finds: String Diagrams, the Number 5, and the Moons of Jupiter.

Update:  Now hilbertthm90 has written This Week’s Finds in Arithmetic Geometry.
