Scrolling down, I see that Laurence Krauss has a project for Darren:
The ultimate goal of physics, as it is often described, is to have a "theory of everything", in which all the fundamental laws that describe nature can neatly be written down on the front of a T-shirt (even if the T-shirt can only exist in 10 dimensions!).

I'm mucking out the house today. How does it get so much stuff in it?

The naughty stuff fairies cart it in in the middle of the night. If you make a present to them by leaving binbags full of stuff by the edge of the road once a week, you should find the amount of stuff eventually decreases.

(Raak) No, the foxes get it. So the fairies don't get their presents and just keep up the pressure.

[Irouléguy] I thought I'd posted this response immediately after your post, but still... when the physicists fulfil their part of the bargain, I'll do mine.
