## Part 1

Part 1 in this series shows some introduction to tensor theory and demonstrates it with the Cauchy stress tensor.

## Part 2

Part 2 visualizes the electromagnetic tensor. Part 2A uses it to represent a magnetic field. In Part 2B we extend it to the electric field as well.

### Different meanings of the term 'tensor'

This series talks about the term ‘tensor’ as used in physics and math. In the field of AI the term tensor was borrowed with a simplified meaning. In AI it simply means a multi-dimensional array. So for example the array “double a[4][6]” (4 by 6 matrix of doubles) is called a second-order tensor, but there’s no special relationship to vector spaces, as shown in the video.
