Every engineering textbook presents the scientific method as a clean, linear process: observe, hypothesize, predict, test, conclude. Every working engineer knows the reality is nothing like that. The real process is messy, iterative, full of dead ends, and often driven by accident as much as intention. Understanding both the ideal and the reality makes you a better engineer, because you learn when to be systematic and when to follow a hunch.
The textbook scientific method versus the messy reality. Debugging is hypothesis testing, design reviews are peer review, test plans are experiments. Case study: Edison's systematic approach to invention.
