Fortran is one of the oldest and most powerful programming languages, specifically designed for numerical, scientific, and engineering computations. While modern alternatives such as Python and C++ are also popular in these domains, Fortran continues to be a preferred language for high-performance computing (HPC) tasks. Its efficiency, ease of use for mathematical computations, and optimization capabilities make it a key player in many scientific fields.
Learning Fortran can be quite beneficial, especially if you’re involved in domains like simulation, computational fluid dynamics (CFD), or scientific computing. This post outlines various resources that can help you master Fortran programming, ranging from books and online tutorials to advanced topics like parallel computing.
