Practical Strategies for Learning to Code in Science and Engineering
Written on
Chapter 1: Introduction to Coding in STEM
Learning to code can be a challenging yet rewarding endeavor, particularly for those in science and engineering. The journey involves identifying suitable resources, collaborating with the right peers, and discovering what inspires you.
Many programming languages exist, each offering unique ways to develop applications. The logic behind coding may not align with our usual thought processes, which can make it daunting, especially if you're learning independently. However, finding a method that suits you can simplify the process. In disciplines like physics or chemical engineering, coding is often an essential skill.
Why Learn to Code?
My coding journey began nearly two decades ago during my undergraduate studies. One of my physics courses required me to self-learn Fortran using an exemplary handbook before completing coursework. This self-directed learning was well-structured and enjoyable, although I never anticipated its future relevance.
Today, the landscape has shifted, with physics students increasingly taught Python— a versatile language that offers numerous specialized packages. For instance, the Astropy package facilitates conversions between various astronomical coordinate systems, allowing students to focus on astrophysics without getting bogged down by coding challenges. Many online resources are available for learning Python, making it accessible even outside a physics degree. The hands-on experiments in physics provide practical applications for programming, enhancing the learning experience.
Section 1.1: The Role of MATLAB and Python
MATLAB, similar to Python, is a powerful programming environment that can manipulate data and control devices, such as robotic arms. Tools like CFTool can simplify data analysis, yet understanding the underlying physics is vital for interpreting results. While coding can automate processes, true insight comes from a solid grasp of your field.
In scenarios involving vast data sets, coding becomes indispensable. For example, particle physics experiments can generate billions of data points, but coding allows for efficient filtering and analysis. By using conditional statements in your code, you can quickly focus on relevant data without manual sifting.

Section 1.2: Coding and Problem Solving
Transitioning from physics to computational chemistry involved creating molecular models. I utilized code to determine if atomic bonds were within acceptable limits. Coding can also handle repetitive tasks through loops, significantly reducing time spent on complex calculations.
Learning to code also involves mastering the debugging process, often leading to those 'aha!' moments. Reviewing another's code can be perplexing, as coding styles vary widely. Clear comments within code can aid understanding, but it still requires time to comprehend fully.
Chapter 2: Motivation through Application
Many self-taught coders find their motivation tied to specific applications. For instance, programming a robotic arm to play chess demands meticulous planning and collaboration among team members from various disciplines. Each contributor brings unique perspectives, enhancing the overall code optimization process.
In chemical engineering, predicting outcomes based on experimental data is crucial. When faced with numerous variables, mathematical modeling can reveal insights beyond direct experimentation, provided that physical limitations are understood and appropriately incorporated into the model.

The second video, "5 Tips for Beginner Software Engineers and Students," offers practical advice tailored for those starting their coding journey in engineering and science.
Benefits of Coding in STEM
Beyond enhancing scientific understanding, coding can open doors to career opportunities. Successfully applying coding skills to solve real-world problems can boost confidence and showcase your grasp of scientific concepts. For instance, filtering a data set with millions of entries or managing complex molecular simulations becomes significantly more manageable with coding.
Many find motivation in applying coding to solve specific challenges. Each person's coding journey is unique, and as you grow more comfortable with your skills, you'll build confidence in your abilities. Spending time coding and debugging fosters familiarity, providing a personal connection to the problems you've tackled.
