Diffie-Hellman vs ECDH Updated 2025-07-16
ECDH has smaller keys. youtu.be/gAtBM06xwaw?t=634 mentions some interesting downsides:

One notable application: cryptocurrency, see e.g. how Bitcoin works.

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.
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.

The Biggest Ideas in the Universe | 11. Renormalization by Sean Carroll (2020)
Source. Gives a very quick and high level overview of renormalization. It is not enough to satisfy Ciro Santilli as usual for other Sean Carroll videos, but it goes some way.

Heisenberg picture Updated 2025-07-16
Basically the same as matrix mechanics it seems, just a bit more generalized.
