This summer I was a research student and my advisor used fortran (case 1). Two of my professors at my college use fortran (case 2). My friend at BU who is just starting his phd says fortran is huge and I should probably get a grasp on it (case 3). On the opposite side of the spectrum, my computer science friends at college laugh at the fact of fortran... Someone in my lab during my summer research believed in the power of IDL which I mainly used, and python. I mean is fortran really that powerful? I mean people stick to what they know, and continue to use fortran but if im proficient at python and for example people in my lab are all using fortran to solve problems I feel like i could easily solve the problems too using python.
