Water Margin Updated 2025-07-16
Talks about rebellion of the oppressed (and bandits), and therefore has been controversial throughout the many Chinese dictatorships.
The book is based on real events surrounding 12th century rebel leader Song Jiang during the Song dynasty.
It is also interesting that Mao Zedong was apparently a fan of the novel, although he had to hide that to some extent due to the controversial nature of the material, which could be said to instigate rebellion.
The incredible popularity of the novel can also be seen by the large number of paintings of it found in the Summer Palace.
This is a good novel. It appeals to Ciro Santilli's sensibilities of rebelling against unfairness, and in particular about people who are at the margin of society (at the river margin) doing so. Tax the rich BTW.
It also has always made Ciro quite curious how such novels are not used as a way to inspire people to rebel against the Chinese Communist Party.

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".

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.

Education is broken Updated 2025-07-16
Once Ciro was at a University course practical session, and a graduate was around helping out. Ciro asked if what the graduate did anything specifically related to the course, and they replied they didn't. And they added that:Even though Ciro was already completely disillusioned by then, that still made an impression on him. Something is really wrong with this shit.
One has to put the bread on the table.

David Deutsch on Education interviewed by Aidan McCullen (2019)
Source. Key quote that hits the nail:
So right... the purpose of education is not to teach facts. The purpose of education is to propose ways of thinking, which students themselves must try to apply and decide if it suits them! And use the patterns of thinking that are useful to reach their goals.
Like Noam Chomsky, he proposes education has been a system of indoctrination more than anything else e.g. twitter.com/daviddeutschoxf/status/1406374921748496386:At twitter.com/DavidDeutschOxf/status/1051475227476185089 another good quote by Churchill:
All compulsory education, "tough" or not, "love" or not, in camps or not, and whether it "traumatises" or not, is a violation of human rights.
Headmasters have powers at their disposal with which Prime Ministers have never yet been invested.
Quote selection by Charles Bukowski (2016)
Source. Generally speaking, you're free until you're about 4 years old. Then you go to grammar school and then you start becoming... oriented and shoved into areas. You lose what individualism you have, if you have enough of course, you retain some of it... Then you work the 8 hour job with almost a feeling of goodness, like you're doing something. Then you get married like marriage is a victory, and you have children like children is a victory... Marriage, birth, children. It's something they have to do because there's nothing else to do. There's no glory in it, there's no steam, there's no fire. It's very, very flat... You get caught into the stricture of what you're supposed to be and you have no other choice. You're finally molded and melded into what you're supposed to be. I didn't like this.

I was trying to learn about how some types of quantum computers work, when I came across this pearl:

Superconductivity Updated 2025-07-16
Experiments:
- "An introduction to superconductivity" by Alfred Leitner originally published in 1965, source: www.alfredleitner.com/
- Isotope effect on the critical temperature. hyperphysics.phy-astr.gsu.edu/hbase/Solids/coop.html mentions that:
If electrical conduction in mercury were purely electronic, there should be no dependence upon the nuclear masses. This dependence of the critical temperature for superconductivity upon isotopic mass was the first direct evidence for interaction between the electrons and the lattice. This supported the BCS Theory of lattice coupling of electron pairs.
