Who wants to join a writing group with me so I can get my math papers finished? My available times are Sunday 5:30-6:30 a.m., Monday-Thursday on lunch break unless I have grading or a faculty meeting, and Friday from 1:30 to oh shoot I have to pick up my kid o’clock.

Yep it's "subposting about how multiple choice tests are terrible for exciting anyone about math who wasn't already excited" season.

Lol they burned through almost double the budget of the American Institute of Mathematics's five year award on this. www.nsf.gov/awardsearch/... The more you think about it, the more of an L this is for "AI Solves Math": call me back when you compare with giving humans the same amount of resources.
