(CdM) Could you move around a bit, preferably completely at random and as fast as possible. Then we will know your location to a greater degree of accuracy than currently specified.
[Rosie] I don't think that works for molecules of CdM. On the other hand, the speed of a flerdle is highly dependent on slope, being relatively speedy now along a flat, perfectly horizontal surface and very much slower on any inclination or declination, whereas say a rock or a basketball shows very different behaviour.
