Fortran (Formula Translation) was the first language to demonstrate that high-level code could match hand-written assembly in performance. It remains in active use for climate models, computational fluid dynamics, quantum chemistry codes, and any domain where numerical performance is paramount. Modern Fortran (2018+) supports coarrays, object-orientation, and interoperability with C.
