    1. Since we have much faster CPUs now, numerical calculations are done in Python which is much slower than Fortran. So numerical calculations basically take the same amount of time as they did 20 years ago.

      Python vs Fortran ;)

    1. One explanation often given is the huge amount of scien-tific legacy code in the world—after all, differential equa-tions remain the same over time and so do their solvers, sothere’s no reason to rewrite such code. But a great deal ofnew code is written in Fortran95 as well. One of us recentlyserved on a review panel for granting computer time tohigh-impact scientific computing applications that effec-tively use thousands of processors, and every single one ofthe applications he reviewed was written in Fortran. At lastyear’s conference on computational physics in South Korea(CCP2006), most of the plenary speakers who talked aboutcodes used Fortran. Perhaps scientists prefer Fortran be-cause they’re productive when using it
