Wave equation solver Updated 2025-07-16
This section talks about solvers/simulators dedicated solving the wave equation. Of course, any serious solver will likely be able to solve a wider range of PDE, so this section contains mostly fun toys. For more serious stuff see: Section "PDE solver".
JavaScript toy solvers:
- jtiscione.github.io/webassembly-wave/index.html circular domain, create waves with mouse click
- dionyziz.com/graphics/wave-experiment/ with useless 3D WebGL visualization :-), waves with mouse click. Solving itself done on CPU, not GPU.
Wave function collapse Updated 2025-07-16
The idea the the wave function of a small observed system collapses "obviously" cannot be the full physical truth, only a very useful approximation of reality.
Because then are are hard pressed to determine the boundary between what collapses and what doesn't, and there isn't such a boundary, as everything is interacting, including the observer.
The many-worlds interpretation is an elegant explanation for this. Though it does feel a bit sad and superfluous.
Wayback Machine rate limit Updated 2025-07-16
archive.org/details/toomanyrequests_20191110 says 15 archives / minute, but apparently aslo 15 retrievals per minutes on Wikipedia, after which 5 min blacklist. After that, you start getting some 429s, and after that, server refuses to connect at al.
CDX: no limits apparently, they might just throttle you? Made 10k requets on bash loop and was going fine. But not that if you get blacklisted by create/fetch requests blacklist, server fails to connect here as well.

- protection against accidental battery inversion
- rectifiers, notably mentions a diode bridge

Ciro's Edict #7 Not work Updated 2025-07-16
I was trying to learn about how some types of quantum computers work, when I came across this pearl:
en.wikipedia.org/wiki/Wolfgang_Paul#Scientific_results Wolfgang Paul, 1989 Nobel Prize in Physics winner, referred to Wolfgang Pauli, 1945 winner, as his "imaginary part".

Web of Stories interview (1996): www.youtube.com/playlist?list=PLVV0r6CmEsFzVlqiUh95Q881umWUPjQbB. He's a bit slow, you wonder if he's going to continute or not! One wonders if it is because of age, or he's always been like that.
There are unlisted articles, also show them or only show them.
