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.

. Source. This image shows well how the diode is only an approximation of the ideal one way device. Notably, there is this non-ideal voltage drop across the device, which can be modelled as constant. It is however an exponential in fact.Diodes Explained by The Engineering Mindset (2020)

- 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".

John Archibald Wheeler Updated 2025-07-16
Richard Feynman's mentor at Princeton University, and notable contributor to his development of quantum electrodynamics.
Worked with Niels Bohr at one point.
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.
John von Neumann Updated 2025-07-16
This is the one Ciro Santilli envies the most, because he has such a great overlap with Ciro's interests, e.g.:
