He also made circuitjs, a very useful circuit simulator which I regularly use for prototyping. It lets you modify and probe elements in real time unlike spice simulators, so it is faster to modify a design in it.
I use spice simulators to check the final design since sometimes circuitjs can have instability issues in complex circuits involving stuff like the nonideal op amp.
He also wrote zsh ( https://en.wikipedia.org/wiki/Z_shell ) as a sophomore in 1990, moved onto other things a few years later, and a couple decades later in 2019 it became the MacOS's default shell.
That's wild. I knew he was the circuitjs guy which is impressive on its own, and vaguely knew of the other simulations as well, but writing zsh as an undergrad... Wow
Does anyone know what are Paul Falstad’s project right now?
(I haven’t seen any new. Not sure if perfect things do not need fixes, or some switch to another field, or a burnout, or he has ascended to godhood - out of a few options.)

I cited it as one of the remarkable steps in the history of educational simulations, https://doi.org/10.1117/1.OE.61.8.081809, figure 2 (a broader overview in https://p.migdal.pl/blog/2024/05/science-games-explorable-ex...)
You can fix the ends of the string by pressing space. When both ends are fixed, you can you can drag the beads and release them.
No big deal, but hey I was quite happy with myself back then..

Never heard until now. Looks interesting. Thanks for sharing, but is it available now?
