time a hundred percent of my work was computational so I did direct numerical simulations of turbulent three three dimensional turbulent flow and the particle movement within that flow now interestingly enough I don't know if many of you know this but the Fortran originally you had to start in the seventh column right so space space space space space space and then you would start your statement and things like line numbers and whatnot could go in the first six but that was a throwback to the old punch card days and
