The closest site of the University of California to San Francisco. Berkeley, California is a small town on the East of the San Francisco Bay.

The second one of the University of California after UC Berkeley.

To get an intuition for it, see the sample computation at: en.wikipedia.org/w/index.php?title=Ackermann_function&oldid=1170238965#TRS,_based_on_2-ary_function where $S(n)=n+1$ in this context. From this, we immediately get the intuition that these functions are recursive somehow.

Ciro Santilli studied there for a few years starting in 2007.

In retrospect, doing electrical engineering (and likey the other engineering degrees) felt like taking a trip to the 60s in the United States, due to both the subject matter, and how old the concrete buildings were!

This does not need to be a bad thing. It is in that era (and earlier) that much of the exciting foundations of the field were set, and there is great value in there is value in tutorials written by early pioneers of the field. Not that they were amazing at excting history lessons as they should be. But the course outline suggested that intent.

But that point of view must also be accompanied by the excitement of the great ongoing advances of technology (and impact they had in the past). And on that, they failed.

One day, one day, we will fix that.

Semi-comical student website to review the toilets of the University of São Paulo. Some of the toilets had a reputation for being terrible.

One is reminded of Crushbridge.

The "Truth and Beauty" motto hugely coincides with Ciro Santilli's ideas.

Truth is easier somewhat as it is more subjective.

Beauty, like all arts, sometimes you achieve, sometimes you don't.

Searcing beauty is a painful thing. You just keep endlessly looking for that one new insight that will blow your mind.

The key missing point would be "usefulness". See also: Section "Art".

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.

Teachers appear to own it, just allowing perpetual non exclusive rights to university: www.admin.cam.ac.uk/univ/so/pdfs/2022/ordinance13.pdf

The courses are highly open, almost everything is given publicly except solutions, many of which are given to teachers only. Well done!
