Show up when solving the Laplace's equation on spherical coordinates by separation of variables, which leads to the differential equation shown at: en.wikipedia.org/w/index.php?title=Legendre_polynomials&oldid=1018881414#Definition_via_differential_equation.

Diffeomorphic to the 3 sphere.

Appears directly on Schrödinger equation! And in particular in the time-independent Schrödinger equation.

Allows you to connect two adjacent pins of a pin header. Sometimes used as a hardware configuration interface!

Ciro Santilli was contributing to this, when CommonMark left private mode and killed it, thus wasting many hours of Ciro's time.

The Khômiss was a Binet that had 12 undisclosed participants every year.

They intentionally projected the idea of a semi scary and cool secret society/cult/Fascist/Gestapo/non-racist Ku Klux Klan-like organization

Khômiss members would wear a face cover whenever they would go out "on duty", notably to break a student's door with a fire axe when some student had fucked up particularly bad.

The Khômiss had an ambivalent character: while on one hand they would punish students that they felt had fucked up, they were actually semi approved by the school's head.

And conversely, they could also play pranks on the school head, e.g. vandalizing their office with funny objects if they had made some decision that was particularly unpopular to the students. This also likely with tacit approval, and as a way to be a "cool independent organization that also represents the students".

As such, the Khômiss aimed to be a sort of a "conscience" of the cohort, punishing the evil deeds of either side.

They were apparently unfortunately disbanded by the school in 2013 it seems, just after Ciro Santilli left. They took some poor student out by car and left him more than 1km outsie of the school for some reason. But he had a cell phone and walked came back, so doesn't feel that serious. Likely the political correctness of the times just caught up with them.

Bibliography:

Ciro Santilli once talked to a man who had been working on high-frequency trading for the last six years.

He was quite nice.

Ciro asked him in what way did he feel his job contributed to the benefit of society.

He replied that it didn't contribute at all. It was completely useless. More than that, it so completely useless, that it was even pure. A bit like advanced mathematics, but not even providing beauty for anybody outside of the company, since everything is a closely guarded trade secret, unlike mathematics which is normally published for the vanity recognition.

And so, Ciro was enlightened.

A great mind can work in the most useless branches of finance, without the desire to improve the world, nor make it worse. Not to compete, nor be afraid, nor anxious. A sand mandala.

Only being. Being, in the exact fraction of a moment where bid meets ask.

Nirvana.
