Bernard The Line Gains a Second Dimension

A very basic introduction to the idea of two dimensions.

L.O. I know what two-dimensional means.

This is a quick video I made about a year ago to solve the problem of a few basic misconceptions that were creeping up with some of my pupils. It’s not thorough and I don’t claim it to be 100% mathematically accurate, but it’s hopefully a good, basic introduction.
