For which there seems to be zero repercussions for ICE. The only case I’m aware of is the one where the agent threw a distraught woman to the floor. He was put on desk duty for a few days and is now back working on the street. ICE has no incentive to stop lying and brutalizing.

I'm ok with an informal proof of l'Hopital's 0/0 based on local-linear properties. (Zoom in, num and denom look like lines, so the ratio is the ratio of the slopes, i.e., the derivatives.) I think whenever possible an informal justification should be given, when we need something b4 we can prove it.

Great! You might modify the code so that the *volumes* (rather than the radii) are proportional to the masses. That is, the "balls" are made of some material with uniform density.

Equangular, equilateral (one does not imply the other, in general!).
Has zero/one/two pairs of parallel sides
All vertices can lie on a circle (e.g., cyclic quadrilateral). All triangles are cyclic.
All angles acute. All angles obtuse. Contains both obtuse and acute angles.
Regular.
Good luck!

I open to seeing potential applications of AI in the math classroom, and what the existance of AI might mean for what we teach and how we teach it.

That said, I've yet to see any evidence to support "AI...reshaping and transforming traditional teaching methods at a breakneck pace."

We live in a world where there are so many stories about unmarked ICE officers taking away people by mistake that it's hard to keep them all straight. That's a statement in and of itself.

When the National Guard Comes to Town

I re-listened to the pod, and it sounds very much like this case. I'd put money on it being the same person. It's the September 8 episode of The Daily from NYT, about 23 minutes into the episode. www.nytimes.com/2025/09/08/p...

* When the government has a stake in the information, don't trust what officials say, particularly high-level partisan ones in the present administration.

Great exercise!

Have you assessed whether all the reported distances are computed "as the bird flies" (i.e. great circle) regardless of roads, vs looking at distances found if one were to actually build a GPS path?

For combinatorics & probability probs my method is:

Step 1 - Find a method to get an answer that you feel confident abt.

Step 2: look for other, maybe more efficient or elegant solns and check against step 1.

Step 3: If not match, dig deep to figure out which is wrong and why!

Did not mean to cause such distress. I have a hair-trigger for falsehoods online from either side. It appears that you and I are in agreement about many/most things (incl. Kirk and the right of "big gay homos" to live free), so it was not my intent to have such an effect on you.

Be well.

Interestingly, that set of 4 values appears in the window (I checked) but not on the website. It says "A place to grow, play, and learn through hands-on, inquiry-based science."

Maybe they contracted out the window design.

DJT: "I could stand in the middle of Fifth Avenue and shoot somebody, and I wouldn't lose any voters, OK? It's, like, incredible."

If he did:

Hegseth would say the victim was a narcotrafficker and would praise Trump for his β€œlethality”.
