       I'm a math person who would like to better understand and appreciate physics. Anyone have any good book recommendations? I'm not looking for a textbook, but I would read a great one!#math #physics

       What should I teach to my geometry students tomorrow? I will abide by the results of this poll.

       I gave my geometry students some ChatGPT-generated "proofs" this week to review. There were several examples, each designed to illustrate a different point. One was a "proof" that the diagonals of a rectangle are congruent, which contained several errors. I was proud that several students immediately identified how dangerous it was: "It sounds like it is correct, until you look more closely at it."#Math #MathEd

       Logged into Twitter to look around, as I occasionally do. I was met with:• Humblebrag moralizing from people who don't understand the morals they are bragging about possessing• Several posts intentionally designed to elicit a negative reaction from me• A few thoughtful posts with no engagement whatsoever• Four people complaining about Twitter and/or social media• Two people I miss hearing from

       @futurebird Curriculum / textbook changes are good for lots of interested parties: They make executives look decisive, they make administrators look busy, they make publishers lots and lots of money. But they make very little difference.
