I contacted Beth. AJP doesn't have paper records from 1998, and double blind review process prevents identifying reviewers. My LinkedIn post made its way to the 2nd author faculty advisor of student who plagiarized my work. He emailed me to apologize. Still don't know how they got those plots.

That's the only explanation I can think of. Back in 1998, there was no electronic submission. I mailed 4 paper copies to editor, who kept one and sent 3 out for review. I'm guessing one of the reviewers kept a copy? Was this author a reviewer? (unlikely), but perhaps saw a copy the reviewer had?

Agreed. I also really prefer white for ambient. I wonder if BuVe is available as a color map option in the current version of Mathematica?
I have tried a Pink-White-Green colormap that also seems to work for most color-blind cases:

I need to spend more time here on your 🦋 pages looking through your new animations. These look really useful. I really hope you are able to gather your all amazing animations together on a website someday.

yes. I've started using a similar "cividis" color map for many of my animations for similar color-blind accessibility reasons -- but haven't had time to go back and re-create all of my animations that use RWB yet.

Those are awesome! I did the same thing (showing the oscillation paths and elliptical motion) for a couple of "particles" in the animations I created for my website in 2014:

I really like the RWB coloring addition to the "Sparrowgram" particle motion on yours.

Yessir.

Thanks! I learned that technique from Tom Rossing in 1990 while I was working on my MS with him.

Except that this thesis explored computer models of hollow aluminum bats that were rigidly clamped at the handle which is completely wrong. So the results of her models are pretty much useless for predicting handle vibration in actual bats or sweet spot location.

How can a person with “zero education” ever learn to ask the right questions? Education in the relevant field is what helps you know the right questions to ask.

Don’t know. I’m a non-tenure track teaching faculty so I don’t have overhead return.
Turns out the architect firm demanded the doors be replace and the contracted supplied is eating the cost. Still seems like an awful waste to me. Doors are going to be discarded to trash.

Where did you get that amazing birdfeeder pole?

Thank you for letting me know you find them useful!

It is a great app! I use it with my undergrad acoustics course - mostly because it looks and behaves the same on both iOS and Android devices. There are some things I wish it did better, but overall I have gotten a fair amount of use out of it. Simple and functional is good.
