FORTRAN remains a relevant programming language for chemical engineers, despite perceptions of it being outdated. It is still utilized in various scientific and engineering applications, particularly because many foundational math and engineering software packages were originally developed in FORTRAN. While some argue that knowing BASIC is sufficient, others suggest that familiarity with FORTRAN can be beneficial, especially for understanding legacy systems and interfacing with modern languages like C++. The language's continued use in specific research areas, such as particle physics, highlights its ongoing significance in certain fields. Overall, while newer languages are gaining popularity, a basic understanding of FORTRAN can still be advantageous for chemical engineers.
