I have cold hives too!!

Not as bad as when I was a teenager, but I still get them all over my back if I hang out in a pool.

How transferrable do you think the skills are to other jobs? Eg would it help a couples therapist or an acting teacher in their job?

I taught at UM for four years, and I was not prepared for how wealth-oriented the students and campus culture were, even compared to Cornell. It's a school for the rich who happen to be smart, not the smart who happen to be rich.

Most of the cast are great singers, but then Santino Fontana starts singing and it feels like watching an NBA player in the Sweet 16. He's just at a different level.

Amazing. As someone married to an artist and art educator, I am always on the lookout for that kind of stuff.

My latest pet topic has been the mathematics of color and visual perception...like the existence of impossible colors or how digital color reproduction only works correctly for humans.

There is also the pedagogical issue of whether to teach things like this first as concepts and then as computations, or vice versa.

It would be insane to teach arithmetic as arcane symbolic manipulation and only later relate it to counting, but this is often how we teach advanced math(s).

Well, the dark side of any mathematical theory is how you actually do any computations with it. Multiplication is a lovely idea and "carrying the 1" is how the sausage gets made.

Or, in your case, linear maps are a lovely idea and matrices are how you compute anything.

Mathematics is about finding patterns common to a variety of phenomena and studying those patterns separate from the irrelevant details.

Eg "four" is the pattern shared by "four apples" and "four sheep", and "addition" is a rule such patterns follow, regardless of what is being counted.

Second, it has a kind of silly, hokey vibe that (I think) is meant to be an affectionate throwback to TV detective shows, like Columbo, Murder She Wrote. My guess is that it's supposed to make the murders feel a little less realistic, but it really didn't work for me.

You may like it, many folks do!

I bounced off of it for a few reasons. First, each episode is a "reverse whodunit", where you learn the murderer in the cold open and the rest is about catching them. For me, it completely flipped the vibe from curiosity to anxiety, which was less fun.

I agree with every part of this...he's been one of my favorite directors since Brick.

What's weird about his 100% rate with Knives Out for me is that I thoroughly did not like Poker Face.

"Death sticks" from Star Wars is my favorite example of nerds being unable to come up with believable drug slang.

Not to get too technical here, but the alligator wants to eat the bigger number.

"Oh, I hated/was bad at math in school."

My stock reply: "Whelp, more for me!" ...and then I turn away from them, indicating the conversation is over.
