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?
Digital signature Updated 2025-07-16
One notable application: cryptocurrency, see e.g. how Bitcoin works.

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.

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?????????
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.
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.
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
