Before diving into the resources, it is important to understand why spreadsheets have maintained their relevance in an age of high-powered engineering software. They offer a unique blend of accessibility, transparency, and customizability. Unlike a "black box" software, a well-built spreadsheet allows an engineer to see every calculation, understand every assumption, and modify any parameter. This builds trust in the results and serves as an exceptional learning tool for students and junior engineers.
