3Blue1Brown

Summary: A mathematics YouTube channel by Grant Sanderson, known for visually-driven explanations of linear algebra, calculus, neural networks, and other topics.

Overview

3Blue1Brown produces animated video lessons that prioritise geometric intuition over symbol-pushing. The channel’s signature tool is Manim, an open-source Python animation engine Sanderson built for the series.
