Fortran: The Language That Revolutionized Engineering

Fortran: The Language That Revolutionized Engineering

In 1956, a group of scientists and engineers at IBM gathered to create a new programming language that would be specifically used for scientific and engineering calculations. The result of their efforts was FORTRAN, which quickly became the de-facto standard for technical computing.

FORTRAN’s success can be attributed to several factors. First, it was easy to use and understand, with a syntax that was similar to ordinary mathematical notation. Secondly, it was powerful, with built-in capabilities for complex numeric calculations and data manipulation. Finally, it was available on a wide range of computers, making it accessible to a large number of users.

FORTRAN had a major impact on the field of engineering. It enabled engineers to solve complex problems that were previously impossible, leading to advances in fields such as aerodynamical, fluid dynamics, and structural analysis. It also played a crucial role in the development of computer modeling and simulation, which is now an essential tool for engineers in a wide range of fields.

In the 1970s, FORTRAN began to face challenges from newer programming languages such as PL/1 and C. However, it remained popular in engineering and scientific computing for decades, due to its large installed base and extensive library of software.

In the 1990s, there was a resurgence of interest in FORTRAN with the development of new versions of the language that offered support for features like modules, dynamic allocation, and array sections. This revitalized FORTRAN’s popularity and it is still widely used today in high-performance computing and engineering applications.

Today, FORTRAN is still a popular programming language in the field of engineering and scientific computing. It is particularly well-suited for applications that require high-performance numerics, making it a valuable tool for engineers and scientists in a wide range of fields.

Here are some example of how FORTRAN is being used today:

  • Designing new materials and drugs
  • Simulating the behavior of complex systems
  • Analyzing the effects of natural disasters
  • Optimizing the design of cars and airplanes
  • Studying the interactions between atoms and molecules
  • Modeling the Earth’s climate

These are just a few examples of the many ways that FORTRAN is being used to solve complex problem in engineering and science. The language is a powerful tool that is essential for researchers and engineers and this versatility is one reason why FORTRAN remains popular today.# Fortran: The Language That Revolutionized Engineering

  • Formatted I/O: Fortran provides formatted I/O capabilities, allowing for precise control over the formatting of input and output data, essential for generating reports and presenting results.
  • Unformatted I/O: Unformatted I/O enables efficient data transfer between Fortran programs and external files, optimizing performance for large data sets.
  • Direct Access I/O: Direct access I/O allows for direct access to specific parts of a file, facilitating efficient processing of large datasets stored on external storage devices.

5. Compiler Optimization:

  • Optimization Techniques: Fortran compilers employ various optimization techniques to generate efficient machine code, improving the performance of compiled programs.
  • Vectorization: Compilers can automatically vectorize loops, taking advantage of the vector processing capabilities of modern CPUs, resulting in significant performance gains.
  • Parallelization: Fortran supports parallelization techniques, enabling the distribution of computations across multiple processors, accelerating the execution of computationally intensive tasks.


Fortran’s impact on engineering cannot be understated. Its focus on numerical computations, extensive mathematical functions, and robust data structures make it ideally suited for solving complex engineering problems. Its continued relevance in modern engineering practices is a testament to its versatility, adaptability, and enduring legacy. As the field of engineering continues to evolve, Fortran will undoubtedly remain a powerful tool for engineers, enabling them to push the boundaries of innovation and transform industries.

  1. Fortran is archaic. Even Java is outperforming it in every aspect. Maybe it is famous in the past, but time change and rust that iron.

  2. Well, as much as I like Fortran, I must admit, it is not a modern language; it was outdated long ago. But hey! it is good to acknowledge the language’s past glory on revolutionizing engineering before young blood languages such as JavaScript took the show

  3. And people say assembly is the hardest language to learn… FORTRAN took that belief and snorted it like a mountain of c0caine

  4. Fortran taught me to appreciate the simplicity and elegance of programming. Not using semicolons was a bit weird at first, but the flexibility of using line numbers is really something else. Sure, it’s not the most modern language, but it definitely has a special place in my heart. I still use it for some scripting and small projects. If you’re a beginner who wants to get into programming, I recommend starting with a more modern language like Python or Java. But if you’re interested in scientific computing or want to learn about the history of programming, Fortran is a great choice.
