For some reason, Ciro Santilli is mildly obsessed with understanding and visualizing the real projective plane.
To see why this is called a plane, move he center of the sphere to , and project each line passing on the center of the sphere on the x-y plane. This works for all points of the sphere, except those at the equator . Those are the points at infinity. Note that there is one such point at infinity for each direction in the x-y plane.

with extra structure added to make it into a metric space.
The Royal Society's Nobel Prize.
royalsociety.org/grants-schemes-awards/awards/copley-medal/ says it is now open to international citizens, but having a quick look at the 2010 awards still suggests that it is very British centric, or at least anglophone centric, much like the society fellowship itself. That's likely the reason why the Nobel prize won, being much more international from the start.
More like a "lifetime achievement" though, rather than the Nobel Prize, which tends to be for more specific achievements.
The best popular Brazilian music (MPB) of all time by
Ciro Santilli 35 Updated 2025-03-28 +Created 1970-01-01
It is such a huge shame that you have to understand Portuguese to appreciate those songs... this is yet another great evil outcome of having more than one natural language is bad for the world.
The good songs stopped before of just after Ciro Santilli was born, they were originally heard by his parent's generation. Those young new kids are boring.
The place to start is definitely the Holy Trinity of popular Brazilian music:
- Caetano Veloso is arguably Ciro Santilli's favorite MPB artist, he has just too many amazing songs, best ones at: Section "The best Caetano Veloso songs"
- Chico Buarque. Ciro's second favorite.
- Gilberto Gil. Perhaps Ciro likes him third because he is the most lighthearted one, although not always: Section "The best Gilberto Gil songs"
Non trinity songs and artists:
Video 1. Preciso Me Encontrar by Cartola. Source. Present in the 1976 eponymous album though it is likely from much earlier.Video 2. Asa Branca by Luiz Gonzaga. Source. Translation: "White wing". Written in 1947Video 3. O vento by Dorival Caymmi (1949)Source. Translation: "The wind".Video 4. Panis et Circenses from the Tropicália: ou Panis et Circencis (). Source. Translation: "Bread and circuses", a famous Latin phrase. Composed by Gilberto Gil and Caetano Veloso and performed by Os MutantesVideo 5. Mistério do Planeta from the Acabou Chorare album by Novos Baianos (1972)Source. Translation: "The mystery of the planet".Video 6. "Senhor Cidadão" from the Se O Caso É Chorar album by Tom Zé (1972)Source. Translation: "Mr. Citizen". This is likely reference to Military dictatorship in Brazil-lingo. This is an anti-Military dictatorship in Brazil song, appears to reuse terms used by the dictatorship propaganda in the song.Video 7. Marimbondo from the "Pirão de Peixe com Pimenta (1977)" album by Sá & Guarabyra (1977)Source.The title is the name of a type of wasp found in Brazil: synoeca cyanea.Video 8. Romaria by Renato Teixeira. Source."Romaria" is the name of a type of Catholic peregrination.Video 9. Metamorfose ambulante by Raul Seixas (1973)Source. Translation: "Itinerant metamorphosis". From the album Krig-ha, Bandolo!Video 10. Ouro de tolo by Raul Seixas (1973)Source. Translation: "Fool's gold". This dude should be a scientist. But well, he went for mystic/artist. Close enough.Video 11. Gita by Raul Seixas (1974)Source. "Gita" must be a reference to the Bhagavad Gita. From the album: Gita.Video 12. Maluco beleza by Raul Seixas (1977)Source. From the album O Dia em que a Terra ParouVideo 13. A telicidade by Tom Jobim (1958)Source. Translation: "Happiness". Composed for the Black Orpheus (1958) film. "Tristeza não tem fim, felicidade sim" (Sadness never ends, but happiness does). The movie itself is OK. Appeals to Ciro's Buddhist sensibilities.Video 14. Chega de saudade by Tom Jobim. Source. Translation: "Enough longing".Video 15. Jorge da Capadócia by Jorge Ben Jor (1975)Source. From the Solta o Pavão (1975) album. The Caetano interpretation is better however, poor Jorge.- Jair Rodrigues
Video 16. Disparada by Jair Rodrigues (1968)Source. This song is simply amazing. Not exactly MPB, a bit more towards country, but close enough. This was as the track of some soap opera.Video 17. Deixa Isso Pra Lá by Jair Rodrigues (1964)Source. Fantastic early example of early rap music!!! This is regocnized example at: www.youtube.com/watch?v=jfnDEuuPq4Q which builds upon the 1964 song. Amazing. An amazing live performance at: www.youtube.com/watch?v=O3E1uHdrJws, only not using that as the default link as it is not from the official channel. - Vinicius de Moraes. Many of his lyrics are poetry. Notably, he has some "children" songs that you think about as an adult and go "oh fuck". For some reason, Ciro can't help but think that he looks like a pedophile, but he doesn't have any scandals apparently, poor dude. He was a drunkard for sure though.
Video 19. Tarde em Itapuã by Vinicius de Moraes (1971)Source.www.dicionariotupiguarani.com.br/dicionario/itapua/ gives the meaning of "Itapuã". It originates from the Tupi Guarani language, and is the name of a beach in Salvador (Praia de Itapuã), to which the song presumably refers: Video 20. Aquarela by Toquinho (1983)Source. This is a mega childhood hit, and it never gets old. Amazing. One of the most brutal memento moris ever?Video 21. Xô Saudade by Alceu Valença. Source. From the 1980 album "Coração Bobo"Video 22. Carcará by João Do Vale (1981)Source.From the eponymous album.Video 23. Carcará by Maria Bethânia (1981)Source. This very good interpretation likely did much to popularize the song.Video 26. Tudo o que você podia ser from the Clube da Esquina album by Milton Nascimento (1972)Source.Translation: "All that you could be".Anti-Military dictatorship in Brazil song, using the common "you means the dictatorship" technique.Video 27. Caçador De Mim from the eponymous album by Milton Nascimento (1981)Source.
Died of cancer at age 53. Ciro Santilli just can't help but speculate that it is linked to radioactivity exposure.
Extremely precocious, borderline child prodigy, he was reading Dirac at 13-14 from the library.
He started working at night and sleeping during the moring/early afternoon while he was at university.
He was the type of guy that was so good that he didn't really have to follow the university rules very much. He would get into trouble for not following some stupid requirement, but he was so good that they would just let him get away with it.
Besides quantum electrodynamics, Julian worked on radar at the Rad Lab during World War II, unlike most other top physicists who went to Los Alamos Laboratory to work on the atomic bomb, and he made important contributions there on calculating the best shape of the parts and so on.
He was known for being very formal mathematically and sometimes hard to understand, in stark contrast to Feynman which was much more lose and understandable, especially after Freeman Dyson translated him to the masses.
However, QED and the men who made it: Dyson, Feynman, Schwinger, and Tomonaga by Silvan Schweber (1994) does emphacise that he was actually also very practical in the sense that he always aimed to obtain definite numbers out of his calculations, and that was not only the case for the Lamb shift.
physicist with lots of focus on politically incorrect/Right wing stuff:
- motls.blogspot.com/ his blog
- physics.stackexchange.com/users/1236/lubo%c5%a1-motl he has lots of contributions to Physics Stack Exchange
- settheory.net/crackpot-physics: some comments about him from settheory.net
One of the leading figures of the early development of quantum electrodynamics.
