How to avoid unwanted encounters in a crowd
Using some fundamental physical properties of diffusion, I shall explain how to avoid unwanted encounters in a crowded place. The model I will discuss has obvious practical applications, such as minimising one's chances of receiving fliers for dubious Fringe productions. Of course, diffusion is ubiquitous in a wide range of physical, chemical and biological situations, and so this talk will be relevant to anyone who ever has to consider small roundish things jiggling around in a moist warm place. For a preview, see A J Bray and R A Blythe, cond-mat/0205381.
