Zen Updated 2025-07-16
Perhaps the appeal of Zen is that it stepped away from Mahayana's "God and entities", and went a bit back towards the Buddhist psychology-like/self improvement grassroots?

Very interesting story! A predecessor to microwave transmission for trading.

How The First Ever Telecoms Scam Worked by Tom Scott (2018)
Source. Amazing how they used control signals to hide the information from officials on either side.

Functional programming Updated 2025-07-16
Even if we cannot do everything in functional, we should at least strive to clearly extract functional substes in what we do.

This is a good project. Limited scope to 2D card-like games, but very good within that scope.
Ciro Santilli used it for the 2D version of his Ciro's 2D reinforcement learning games.
Used to identify organic compounds.
Seems to be based on the effects that electrons around the nuclei (shielding electrons) have on the outcome of NMR.
So it is a bit unlike MRI where you are interested in the position of certain nuclei in space (of course, these being atoms, you can't see their positions in space).

What's Nuclear Magnetic Resonance by Bruker Corporation (2020)
Source. Good 3D animations showing the structure of the NMR machine. We understand that it is very bulky largely due to the cryogenic system. It then talks a bit about organic compound identification by talking about ethanol, i.e. this is NMR spectroscopy, but it is a bit too much to follow closely. Basically the electron configuration alters the nuclear response somehow, and allows identifying functional groups.
Nu (letter) Updated 2025-07-16
Why would physicists use a letter such that:
  • the upper case version looks exactly like an upper case N. At least that is the correct pronunciation/name/historical successor of .
  • the lower case version looks exactly like a lower case V
Why? Why?????????
Physics from Symmetry by Jakob Schwichtenberg (2015) page 66 shows one in terms of 4x4 complex matrices.
More importantly though, are the representations of the Lie algebra of the Lorentz group, which are generally also just also called "Representation of the Lorentz group" since you can reach the representation from the algebra via the exponential map.
clang Updated 2025-07-16
LLVM front-end for C and related language like C++ etc.
Coulomb gauge Updated 2025-07-16
Alternative to the Lorentz gauge, but less used in general as it is not as nice for relativity invariance.
Lorentz boost Updated 2025-07-16
Two observers travel at fixed speed relative to each other. They synchronize origins at x=0 and t=0, and their spacial axes are perfectly aligned. This is a subset of the Lorentz group. TODO confirm it does not form a subgroup however.
Ciro Santilli hates it when an expert does this!!!
If you estimate that the audience won't know the name of the concept, that's fine, do explain it as well.
But you must also give the name!!!
This also manifests itself when news outlets omit foreign names from headlines, notably Chinese, but likely happens to all non-european languages too.
LLVM Intermediate Representation Updated 2025-07-16
Very hot stuff! It's like ISA-portable assembly, but with types! In particular it also it deals with calling conventions for us (since it is ISA-portable). TODO: isn't that exactly what C does? :-) LLVM IR vs C
