Oh no. They've hidden the insert equation in google docs... I could maybe forgive them if there was a keyboard shortcut.... (yikes, found it for windows: alt-i then y then e)

Whoa, check this youtube channel out. Sara and Sean (Sweeney) are live making a very cool sketch. Miss on the intro music though. Big Sarah and Duck fans would want: Sara and Sean (QUACK).
Graph Time with Sara and Sean is here!
On today's episode we try to recreate the vibe of one of the first graphs that ever inspired Sean in Desmos. Watch us play with math and maybe learn a thing or two about graphing along the way!

tho i see many anti-AI views among mathematicians and math educators, i hope that this growing list of AI uses in maths can be of some interest:

i was certainly surprised to see the GPT use downthread here!

Never saw a graphical description of the difference of squares factorization so I made one. I don't know why.

"Replace your x's with negative x's; if it stays the same then you have even symmetry" sounds like a Taylor Swift song.

I don’t remember what the Wongs had to say but maybe the most important thing to do on the first day of school is to set a vibe (as the kids say). Who is this weird adult that I’ll be struck with for the rest of the year? Is this a place of intellectual safety and hence exploration?

White House (hence NSF) has also defunded PAEMST program. Lovely.
🚨 Major shake-up in NSF funding for K-12 STEM ed:
Caps proposals at $750K max for 3 years. Prior cap used to be $5M up to 5 years for some programs.
Archives several existing programs (DRK-12, AISL, CSforAll, TD, parts of ECR:Core). Combines into broad program with much lower expected # of awards.

Hey Geometry teachers! Check this out making parabolic solar collectors, and then more useful “compound solar collector”. Can you follow along with the geometric construction?
