People there are gurus of modern Fortran and are very willing to help.

Most other ‘modern fortran’ books assume you have knowledge of older fortran versions.
At the same time I'm looking forward to complimenting it with another go at Silvanus P. Thompson's Calculus Made Easy so I can hopefully get a better understanding of the models described in the fortran book. (Been working through Khan Academy material in the meantime as a prelude...)
I've also got the latest installments in Sammy Harkham's Crickets series and Sam Sharpe & Peach S Goodrich's Viewotron series on deck which I've been saving as a treat. They're both published so infrequently I wanted to save them for some time can sprawl into my reading.
