In Fall 2007, used velociraptors and chem graders as the predator and prey, respectively, in a predator-prey model.
ProfessorLevy taught Math 180 (aka AppliedAnalysis?, more accurately, PDE) in Fall 2008. The last hw assignment was to "creatively summarize the class". AlyssaDray, KwangKetcham, and SarahFletcher interpreted this as "prank ProfessorLevy's office." Thus the AdvectionWhale? was created (in a style reminiscent of the RhinoceRose) and her office was converted into an "ocean of PDE". This made ProfessorLevy very happy - she is a big fan of pranks.
