Science is great and all, but sometimes it can get a little dense. There's nothing that can ruin the enjoyment of the wonder of the universe by coming up against an impenetrable wall of jargon or, worse, maths. Don't despair though, because so long as all you want to do is grasp the concept, there are plenty of way to explain some of the most complex scientific concepts out there. Now, obviously, all analogies by their very nature have flaws and inaccuracies, that's why they're analogies. You could argue that trying to explain the majority of scientific concepts requires the use of analogies if you want to avoid conversing in pure maths. These are also a great way of explaining these concepts to your dad/granny/friends at the pub and making yourself sound super-smart in the process (and, as we know, chicks dig guys/girls that can explain quantum mechanics using everyday items and a bit of cunning).
