3Blue1Brown

3Blue1Brown's third deep learning chapter gives a visual, intuitive account of backpropagation and what happens to a neural network as it learns. A follow-up video covers the underlying calculus.
Recommended as the most accessible introduction to backprop for people who struggle with the pure math.
