New Scientist 9 Feb 2002: p 51 On Brownian movement: .......Contrary to what many textboods state, Brown actually observed the motion of much smaller particles inside fluid filled voids within the pollen grains. This no doubt sounds like tiresome nit-picking.but as Einstein's analysis of Brownian movement shows, the effect is far smaller for relatively huge pollen grains than it is for the particles inside them.
Confusing the two has in the past led to accusations that Brown could not possibly have seen the effect which bears his name. It would be a shame to rob someone of his claim to fame simply because the textbooks can't be arsed to get the facts straight. Robert Matthews, Oxford
