Probably the first time that big wrecker was called to recover a motorcycle.

even google AI can't decipher that one for me

I think that is overstating, see, e.g. $$\frac \pi 4 = \sum_{k=0}^\infty \frac {(-1)^k} {2k+1}$$ Oops, it seems @jedishrfu beat me to this idea

Fascinating video. At first I thought "47 minutes, no way I'm watching that." Glad I did.

@berkeman you beat me to it. An operational definition of "a wave" is, "a phenomenon consistent with the wave equation."

My suggestion is to do it Chet's way first. Before diving into a CFD. The more you understand the physics, the better your CFD model will be. I've seen spectacularly bad (though colorful) results.

What do you have in mind for 'simulation software?'

I think it's Babylonian or Mayan counting.

No doubt, the tactical screwdriver bits are "machined from billet"

Off hand I would suspect that the vast majority of teachers (and students) don't really know how to teach (and learn) "using computers." I could be wrong about that: I'm so out of date that Jimmy Carter was president during my most recent classroom activity. Teachers have been lecturing...

Best part of the sandwich?

In other words, one-on-one dialog between student and teacher. The student beer bar in Williamstown is called "The Log" Regarding books vs. screens, my feeling is "books" are better. But that might be because that's how I learned. I think they said similar about whiteboards: "Chalk on a...

I never would have guessed that 'communication towers' were that tall.
