How to rotate in higher dimensions? Complex dimensions? | Lie groups, algebras, brackets #2

Part 3:    • What is Lie theory? Here is the big pictur...   Around 11:50, can't imagine that this error got in - it should have been SU(n) = {U in U(n), det U = 1}. Orthogonal and unitary groups. Rotational symmetries, real and complex, are particularly useful in the field of Lie theory, because their (complexified) Lie algebras, together with that of the symplectic group Sp(n), are the only infinite families of simple Lie algebras. This video is to familiarise with the SO(n), SU(n) notations, and provides further motivation to study Lie theory.

If you are wondering how I made all these videos, even though it is stylistically similar to 3Blue1Brown, I don't use his animation engine Manim, but I use PowerPoint, GeoGebra, and (sometimes) Mathematica to produce the videos.
