Covariant and Contravariant components and what does metric have to do with it

A try on a simple explanation of the necessity of introducing two kinds of components of vectors - covariant and contravariant, of the differences between them, and of the metric and its role in distinguishing between the two.

..."a very compressed version"... right. :D I recommend watching at larger speed, say 1.25 or 1.5.

The video is heavily spiced with an intense aura of awkwardness surrounding the (better for him!) invisible narrator. :)
