Another New Scientist Article

Found another article:

The Great Brownian Motion Swindle

This is now obsolete, of course - with microscope cameras linked to projectors it's now easy to show the experiment to a whole class.

I think there was one more article, but I can't find it - maybe they rejected it.

Forgot to say that if a password screen comes up on either article just press cancel a few times - it goes away eventually.
