Fortran 77 for Engineers and Scientists is a half century old programming language used throughout the world for solving problems in science and engineering.
This book has the sweetest cover of any FORTRAN book I've ever seen. This is a great FORTRAN 77 resource complete with program composition diagrams and full example programs that are pertinant within the sciences. I always liked FORTRAN 77 more than FORTRAN 90, this book goes much further into the numerical applications of programing than the FORTRAN book I learnt from. Totally awesome!
