Guitar Updated 2025-07-16
The guitar is a highly imperfect instrument if compared to something like a piano, which is much more mathematically elegant.
However, Ciro Santilli just loves this imperfection for some reason, especially in the case of the electric guitar.
Bending, sliding and strumming just feel to good to not have.
And Ciro sucks are doing things in parallel, so the more single threaded approach of the guitar fits his brain/abilities better.
For those reasons, the electric guitar is Ciro's favorite musical instrument.
Piano Updated 2025-07-16
The piano is the most elegant non-electronic instrument. But it requires way too many strings, so expensive and not portable.
Also it allows for no legato or vibrato.
The guitar is kind of the opposite.
After computer sound synthesis however, all of these distinctions become meaningless.

Pop music cannot be good by definition: any art that appeals to the masses (Popular!) has to be a boring watered down version of everything, and therefore boring shit. Just like the movies: high budget movies are shit.
Until maybe one day we can actually get a decent education for everyone.

Modular exponentiation Updated 2025-10-14
Can be calculated efficiently with the Extended Euclidean algorithm.
The beauty of this algorithm is that because exponentiation grows really fast, there is no hope that we can ever learn all the digits of an exponential, as there is simply not enough time or memory for that. Therefore, a natural sub-question is if we can know some part of that number, and knowing the smallest digits is the most natural version of that question.

Electron microscope Updated 2025-07-16
All of them need a vacuum because you can't shoot elecrons through air, as mentioned at Video "50,000,000x Magnification by AlphaPhoenix (2022)".

X-ray crystallography Updated 2025-07-16
One of its main applications is to determine the 3D structure of proteins.
Sometimes you are not able to crystallize the proteins however, and the method cannot be used.
Crystallizing is not simple because:
  • you need a considerable amount of the protein
  • sometimes it only crystallizes if you add some extra small chemical that stabilizes it
Cryogenic electron microscopy can sometimes determine the structures of proteins that failed crystallization.
