A Mathematical Interlude...

I have composed a quick test that can be used, to determine whether you been studying maths with the O.U , for too long:

1.  Read the following joke.  If you laugh, then you have done too much studying.  I recommend that you take 6 weeks off.

Joke:

Q:   What's a rectangular bear?
A:    A polar bear after a coordinate transform!


That is all.
