Desmos interaction developer in NYC. Used to be university prof doing neuroscience, far happier in math ed. I enjoy making math games, in Desmos and also p5play. rajeevraizada.github.io
Question for the hive-mind: there are lots of examples of people being bad at estimating conditional probability (base-rate neglect, etc.).
Are there any special circumstances in which people tend to be *good* at estimating it?
I've been trying for ages to make a simple math game that is actually fun. I think this addition-game might achieve that? Please let me know what you think!

Key ingredients: game is made of math, rather than math bolted on. Starts easy,gets harder. #iteachmath
Question for the hive-mind: what are some good math problem-solving AI systems that you can freely explore, e.g. by downloading & running code from Github? Recent Math Olympiad question-answering systems that made headlines are not available, but maybe some less recent ones are?
People sometimes use neuroscience to explain free-will, e.g. @wiringthebrain.bsky.social. However, the question is whether we can justify the claim that normal human adults have more moral responsibility than babies, or the insane, or grizzly bears. But: neurally they're all made of the same stuff
Jumping on the bandwagon of asking GPT4 to generate an image and then make it even more so. Because, hey, it's fun. Also, it's interesting to see the data-mining-driven caricatures that emerge.
Here's one of personal interest to me:
"Make a picture of a math teacher" #iteachmath
Philosophers: you know that sensible-sounding argument that leads to a desirable conclusion? If you look at it really closely, it falls apart.
Scientists: we don’t need to worry about whatever those philosophers are wasting their time on. Here’s a sensible-sounding argument…
🎢🍎♾️ You can program TONES into Desmos now!
This is going to make teaching about sound more fun (but also possibly more annoying)

@wiringthebrain.bsky.social I've started reading your book Free Agents. I'm trying to get a better sense of what counts as agency: a cockroach scuttling from light: no. A person doing something for a reason: yes. Curious about what counts as a reason. Could a chess-playing AI count as having agency?
This is probably not useful for the learning, but one of my most "Really, that works?" moments with Desmos was how easy it made Voronoi diagrams

It turns out that the new Desmos 3D can show vector arrows and has a built-in cross-product operator. The d/dx and d/dy functions successfully compute partial derivatives. Great for plotting surface-normal vectors #iteachmath ♾️ Animated gif: media.giphy.com/media/iqLTC6...desmos.com/3d/4468e57dba
Couple of suggestions and bug-fixes for new Desmos 3D (which is wonderful, and works great overall).
1. "Translucent surfaces" pref should get saved with graphs. Better, if poss: each surface could have its own alpha.
2. Floating help text for sphere() incorrect. See: media.giphy.com/media/v1.Y2l...
Playing more with new Desmos 3D. Here's a ball rolling around a Möbius strip, needing two round trips before returning to its starting point: www.desmos.com/3d/54781b6fef

Suggestion: turn on "translucent surfaces" pref, which doesn't save with graph. ♾️
Playing with the new Desmos 3D beta. I've been wanting to make a Lorentz "butterfly" attractor for a while, so here's one: www.desmos.com/3d/776a7814bd
It stops itself after 500 steps, because the graphics get laggy beyond that. Link to animated gif: media0.giphy.com/media/ND2gIb... #iteachmath ♾️
I'm playing around with making things that could be useful building-blocks for math games, using the javascript library p5play. Here, individual points spontaneously attract and repel each other to form clumps with exactly 10 members. #iteachmath #MTBoS #EDUsky replit.com/@raizada/v12...
Great Q posed by @mpershan.bsky.social: is there an app where you draw a distance vs time graph and it makes the velocity vs time graph? No such app seemed to exist, so I wrote one using p5play: rajeevraizada.github.io/Pos_veloc_gr...
I hope #iteachphysics & #iteachmath folks find it useful! #EDUsky
I'm curious: any NYC-area math edu folks interested in getting together occasionally to chat about making math games, and to bounce ideas off each other? Personally, I like making online math games (Desmos, javascript). But any type of math game would be interesting #iteachmath #EDUsky
