We've discussed it, and the fruit flies and I have agreed to just live together and split the mortgage 50:50.

Two tropes in recipe videos that I abhor:

Feeding the dog some of your food (gross)

Squishing a sandwich or burger to make the juice / cheese ooze all over the place (also gross)

(Also not a fan scraping the knife across a piece of allegedly crispy food but whatever)

Oh man these are both good suggestions @k8nowak.bsky.social and @triangleman.bsky.social.

I'm ashamed to say it, but I got in a long argument with chatgpt about the area between the polar curves r=2 and r=2sin(theta).

We have agreed to disagree.

Ooooooh I would LOVE that! I had toyed with the idea of making Calc Warm ups my summer project so this would save me a ton of time that I could spend destroying my backyard instead !

I do feel like Desmos Activity Builder might be a weekly (or nearly so) staple along with regular online homework.

I'm teaching an *asynchronous* online Calc class in the Spring Semester. This is the first time I've taught in this manner. Any resources/blogs/videos/books/models or just plain ol' suggestions are very VERY welcome. #edusky #mathsky #iteachmath

Three venn diagrams
1) two circles overlapping 
2) circle (pck) within a larger circle (ck)
3) same circle 
4) question mark

Three venn diagrams 1) two circles overlapping 2) circle (pck) within a larger circle (ck) 3) same circle 4) question mark

Gonna engage some first year grad students in a conversation about content knowledge (CK) and pedagogical content knowledge (PCK).

Which Venn diagram do you think best represents our current understanding of the interaction between the two? Or what would your venn look like?
