If we're introducing ourselves, hello! I'm Jacob. I was born at an early age, and teach math at a small college in a moderately large United State. I sometimes post games, puzzles, animations, or other tidbits, and I read and often share all the nifty tidbits that others post. I like math! I have written about monoidal categories and other highly-structured categories but I poke my fingers in all the mathematical pies pretty happily. Here's the full version of my profile pic. TTFN.
I made a version of Piet Hein's two-dimensional nim-like game "TacTix" that you can play in your browser. Give it a try and let me know if it needs any fixes!
Need a puzzle? May I recommend my Port-and-Sweep solitaire puzzles? (There are two of the short puzzles on this page that still vex me when I try to solve them). Fun stuff if you enjoy peg solitaire or similar puzzles.
If at some point later today I attempt to mark a block of text using ^KB ^KK, then I am going home and not coming back until after spring break.
