A trip through silicalite space
Red rocks represent pore walls of a silicalite zeolite and the white "pearl necklace" are hexane molecules. The molecules seem to be moving continously and, hence, deterministically which would suggest that the movie was generated by molecular dynamics snapshots. But perception can be deceiving. In fact, the movie is based on Monte Carlo data where I have chosen number of trial moves and sampling frequency intelligently. That is, the molecules do, on an average, change their positions slightly from frame to frame but in an entirely random manner - not deterministically. The related article can be found [here].
