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.

Maybe those are genial. Maybe not. Nostalgia is just too strong to discern. Ciro still goes back to them for rest.

Like cysteine, but with selenium instead of sulfur.

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

TODO original experiment?

Laughlin paper: 1981 Quantized Hall conductivity in two dimensions.

Shows a cool new type of matter: Abelian anyons.

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".
