math.stackexchange.com/questions/41706/practical-uses-of-matrix-multiplication/4647422#4647422 highlights deep learning applications.

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

Solving differential equations was apparently Lie's original motivation for developing Lie groups. It is therefore likely one of the most understandable ways to approach it.

It appears that Lie's goal was to understand when can a differential equation have an explicitly written solution, much like Galois theory had done for algebraic equations. Both approaches use symmetry as the key tool.

There aren't any, it's useless:

Archaea are much more closely related to the eukaryotes than bacteria, see e.g. Figure "Coral of life by János Podani (2019)" which shows how archaea diverged from eukarya almost 2 By after LUCA!

It therefore appears that the mitochondrial endosymbiosis happened when a bacteria like cell joined up with an archaea.

Some notable points in which archaea look more like eukaryotes than bacteria:
