Electron Microscope Grid Adventure

This illustrates use of floating point spatial models to investigate objects on wide ranging size scales.  The specific example involves examination of solar flare tracks in an enstatite lath, collected in the earth's stratosphere by a U2 aircraft in an attempt to capture fragments of interplanetary dust not heated significantly by atmospheric entry.  What number density of tracks do you find in this grain, and what lifetime in near earth-orbit does this suggest as a result?  The use of nanoscale simulators is discussed in more detail in "Microscopic perspectives on informal, introductory and industry challenges" (P. Fraundorf and Jingyue Liu) in Nanoscale science and engineering education (ed. A. Sweeney, Amer. Sci. Publ, NY, 2007).  Related tools may be found here.
