Something is useful if it either:

This was the first large part of the genome that was sequenced, in 1981: Cambridge Reference Sequence. Presumably they picked it because it is short and does not undergo crossover.

About 16.6 kbp:

TODO: many places say "exactly" 16,569, it seems that variable number tandem repeat are either rare or don't occur!

One of the things Ciro Santilli most deeply despises.

Real luxury is to understand quantum field theory and number theory.

Clothing/jewelry/car luxury is at worst a way to show off. And at best a replacement for nature/the countryside. People living in big cities have lost nature, and to some, looking at luxury goods (or watching television) serves as a (unsatisfactory) replacement.

Ciro Santilli took courses once upon a time, maybe that has influenced his passion? Ciro Santilli's musical education.

See: math.stackexchange.com/questions/579453/real-world-application-of-fourier-series/3729366#3729366 from heat equation solution with Fourier series.

Separation of variables of certain equations like the heat equation and wave equation are solved immediately by calculating the Fourier series of initial conditions!

Other basis besides the Fourier series show up for other equations, e.g.:

TEM: sample has to be very thin, you get a 2D image. Higher resolution possible.

SEM: sample does not need to be ultra thin, you get a 3D image. Lower resolution possible.

Like cysteine, but with selenium instead of sulfur.

The weird one, not directly coded in the genetic code.

Receptor in SARS-CoV-2 cell entry.

Ah, the jewel of computational physics.

Also known as an ab initio method: no experimental measurement is taken as input, QED is all you need.

But since QED is thought to fully describe all relevant aspects molecules, it could be called "the" ab initio method.

For one, if we were able to predict protein molecule interactions, our understanding of molecular biology technologies would be solved.

No more ultra expensive and complicated X-ray crystallography or cryogenic electron microscopy.

And the fact that quantum computers are one of the most promising advances to this field, is also very very exciting: Section "Quantum algorithm".
