Buffon is the launch point of a favorite book about one of my favorite fields, D. A. Klain, G.-C. Rota, *Introduction to Geometric Probability*, Cambridge, 1997. There is also Waymire’s introduction and extension to “Brownian noodles” in *AMM*. Ideas on extensions abound, e.g., what if the walks aren’t Brownian but Levy flights or something? And, with adequate time, I’d ask questions like suppose one did semi-structured explorations of a posterior probability surface, where the local explorations were effectively such walks, but these informed bigger steps across the surface? These might include the Wang-Landau which you, Professor Robert, kindly introduced to me.
My present interests are modest. In retirement, I’ve become an amateur bryologist with a strong quantitative inclination, resurrecting some training in Botany in college. I’m interested in estimating rates of growths of moss patches, using a adaptation of a technique from forestry, *line intersect sampling*. To close the circle, that’s based upon Buffon’s needle, as by De Vries, 1986 (*Sampling Theory for Forest Inventory*. Springer Verlag).
