Visualizing quaternions
An experiment with a new type of educational media. Check out this first series of "explorable videos" I developed in partnership with Grant from the YouTube channel 3blue1brown. In this series, Grant explains quaternions, a four-dimensional number system that can be used to describe 3d rotation.
