Vector Multiplication and Geometric Algebra
Freya Holmér · Talk · YouTube title: Why can't you multiply vectors?
Why it's here
HN treats it as the best entry point to geometric algebra and an intuitive route to understanding quaternions.
What it covers
Freya Holmer's Dutch Game Day 2023 talk asking why vectors can't be multiplied, building from complex numbers to a single axiom and arriving at geometric algebra, quaternions and multivectors.
