Neuro-symbolic AI Updated +Created
An IBM made/pushed term, but that matches Ciro Santilli's general view of how we should move forward AGI.
Ciro's motivation/push for this can be seen e.g. at: Ciro's 2D reinforcement learning games.

No 2x2 examples please. I'm talking about large matrices that would be used in supercomputers.

Terminal multiplexers are CLI desktop environments Updated +Created
If we didn't have GUIs, terminal multiplexers would be our desktop environments. E.g. they handle stuff like:
  • window switching
  • copy pasting across windows
  • screen locking
  • clock on the status bar (same one that holds tabs)
It is a thing of beauty.

One of the most nerve wrecking movies ever made. Until they decide to rescue their colleague from jail, then it just becomes too surreal.
MuseScore Updated +Created
This software feels amazing. You can really start composing very quickly, lots of features, good keyboard shortcuts.
GPL, and there's a backing company that makes money with an online and mobile version of it.
Can export to:
Ubuntu 20.04: sound preview worked, first hat that trailing Contra-like sound artifacts (like spd-say), but then it went away?
Feels like a lot of effort was put into usability, including keyboard shortcuts by default, seems like a powerful and easy to start using software to compose music!
Einstein solid Updated +Created
One important quantum mechanics experiment, which using quantum effects explain the dependency of specific heat capacity on temperature, an effect which is not present in the Dulong-Petit law.
This is the solid-state analogue to the black-body radiation problem. It is also therefore a quantum mechanics-specific phenomenon.
Quadratic form Updated +Created
Multivariate polynomial where each term has degree 2, e.g.:
is a quadratic form because each term has degree 2:
but e.g.:
is not because the term has degree 3.
More generally for any number of variables it can be written as:
There is a 1-to-1 relationship between quadratic forms and symmetric bilinear forms. In matrix representation, this can be written as:
where contains each of the variabes of the form, e.g. for 2 variables:
Strictly speaking, the associated bilinear form would not need to be a symmetric bilinear form, at least for the real numbers or complex numbers which are commutative. E.g.:
But that same matrix could also be written in symmetric form as:
so why not I guess, its simpler/more restricted.
