The Mathematician’s Weapon | An Introduction to Category Theory, Abstraction and Algebra | #SoME3

A gentle introduction to the study of Category Theory and Abstract Algebra, done from the ground-up by exploring the mathematical weapon of abstraction. This video aims to give an overview of the fundamental tool at the forefront of pure mathematical research: abstraction. By seeing this tool in various contexts, and how it allows us to encounter Category Theory in a natural and intuitive manner, we’ll see how beautiful the abstract can really be.
