Who do you know, after all?

What on earth is this? Some simple computer science made it into the world's most famous journal (5,5). [Yes, its a small world after all. Rae Min's post correctly identified this as the small world phenomenon. David Coles followed up with a reference to the original 3-page article in Nature (read it here) and a more authoritative (?) source (ABC's Dr Karl). We'll look at such structures more closely in lectures this week.]
