While in Brazil, Ciro Santilli used to walk through the outskirts of a small favela to get to university every day, the Favela de São Remo.
See the street view for: R. Catumbi - Vila Butantã Vila Butantã, São Paulo - State of São Paulo, Brazil, e.g. with this link.
To the left, the outer walls of a large police station, with concertina wire on top and all.
To the right, dudes selling drugs on the entry of a small corridor street, presumably to which they could easily escape to in case of need.
The cops could have identified the dealers with binoculars if they actually wanted to!!!
The drug sellers did keep the peace in their business area, and Ciro never got robbed, and would come back from university parties on foot late through the favela.
But Ciro's friends did say that things got much worse after Ciro left, for example a flash kidnapping was reported in 2015.
Wikipedia says that this favela started in the 60s and 70s as settlements of the builders of the University, and that many of the people there still work for the University.
This is consistent with the terribly old buildings Ciro saw when he was at university. They even had the building skills to build their own homes.
The state just has to either legalize those people, or give them houses somewhere else nearby. A world class University is the most important thing a poor country can have, and its image cannot be jeopardized like that.
The existence of that favela, right next to one of the most important universities in Latin America, puts Brazil's surreal social inequality into perspective. Especially considering that before extremely heavy university entry quotas were added, basically all students of the university (or at least of the courses that lead to high paying jobs) had attended private schools, and therefore were not of the poorer classes (see passage about 10 out 500 passage from Section "Free gifted education").
The janitors of the apartment block Ciro lived all lived in the favela. Yes, in poor countries lives are worth nothing, and some poorer people work by watching the entrance of buildings of less poor people 24/7 to guard it from other even more desperate poor people who might want to rob the not so poor inhabitants. They also do janitor jobs like cleaning common areas in parallel.
They were incredibly nice hard-working people, and Ciro spoke often with them. If only given the opportunity, those people could be amazing engineers or scientists obviously. Ciro was also glad to be their friends, and sat down with them quite a few times for several minutes after coming back from University parties, partly because he felt bad about them having to work at that time, but also partly because he just liked them. And they were always up to date on who had come back with a girl to the apartment or not. Ciro imagines that if it had been him, it would have been a perfect bragging opportunity ;)
They had "nothing" but were still happy. This is true wisdom, and a good reminder that all our non-transhumanist technical goals are nothing.
We must destroy social inequality.
There are only boring exampes of taking an uncomputable language and converting it into a number?
Besides the angular momentum in each direction, we also have the total angular momentum:
Then you have to understand what each one of those does to the each atomic orbital:
- total angular momentum: determined by the azimuthal quantum number
- angular momentum in one direction ( by convention): determined by the magnetic quantum number
There is an uncertainty principle between the x, y and z angular momentums, we can only measure one of them with certainty at a time. Video 1. "Quantum Mechanics 7a - Angular Momentum I by ViaScience (2013)" justifies this intuitively by mentioning that this is analogous to precession: if you try to measure electrons e.g. with the Zeeman effect the precess on the other directions which you end up modifing.
TODO experiment. Likely Zeeman effect.

Once upon a time in the west (1968) by Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01
Has the best opening scene of all time.
Top quotes:
- 3 evil guys: looks like we're short one horse. The good guy, shaking his head: you brought two too many.
- "So, you found out you're not a businessman after all." dialogue, see: www.imdb.com/title/tt0064116/characters/nm0000314
Respect, big respect to those people.

Rich people who create charitable prizes are often crooked by Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01
A friend of mine who's a rich man - he invented some kind of simple digital switch - tells me about these people who contribute money to make prizes or give lectures: "You always look at them carefully to find out what crookery they're trying to absolve their conscience of."
TODO who was he talking about? Robert Noyce or Gordon Moore feel likely candidates:
But do you know what, Cirism is totally fine with taking indulgences to absolve someone from their past sins, so long as they have repented. Everyone deserves a second chance.

Initially a phenomenological guess to explain the periodic table. Later it was apparently proven properly with the spin-statistics theorem, physics.stackexchange.com/questions/360140/theoretical-proof-of-paulis-exclusion-principle.
And it was understood more and more that basically this is what prevents solids from collapsing into a single nucleus, not electrical repulsion: electron degeneracy pressure!
