You gotta admit, the shade thrown by the photographer and editors of Bill Buckner's 1990 Upper Deck card is epic.

My two Denison summer research students presented their research yesterday. Lots of good stuff on Bench Mark Butte in Oregon and the composition of quartz in Ohio sandstones (note: one student is in Rome, so her poster was there but not her!)

Big earthquake in Colombia today. M7.4, relatively deep it seems (100 km) and to the west of the big cities. Still, likely damaging.

Thank you, Mr. Scalzi, for some required reading to give to my students this fall. I am going with a hard AI ban (with a signed no AI contract). I think this paragraph from Scalzi's piece nails the pedagogical logic behind such a ban.
Just like being good at Guitar Hero does not make one a guitar player, being able to prompt doesn’t easily make one a creator. At best, it tells what is essentially a statistical engine what you want it to output based on the vast database of other people’s work that it is drawing from. Nothing it cobbles together gives you the experience of creation; the only benefit of that crank of the “AI” flywheel is to the company that owns the “AI.” The image or music or video or text is not from you, it’s just something you asked for. You’re not the creator. You are, perhaps, the creator’s manager.
