Vector fields

A drawing my fields lecturer drew as an example of a vector field.

Played a rather ridiculous game of Irish Snap with some of my coursemates between our lectures this morning. Some of them had added several rules while playing it yesterday, and refused to tell the rest of us the rules before we started the game, so as you can imagine it got pretty confusing. My theory is that we're actually unconsciously craving the utter confusion that resulted from last semester's maths lectures, and so we're trying to replicate it.
