Falsifiability: Testing to Fail

Fri, 03 Apr 2026 12:23:50 GMT

Models, Maps, and Reality

Fri, 03 Apr 2026 12:23:50 GMT

Every simulation, every schematic, every equation is a model. It captures some truth and ignores the rest. Understanding the relationship between models and reality is what separates engineers who build things that work from engineers who build things that merely pass simulation.

Paradigm Shifts: How Engineering Knowledge Evolves

Wed, 18 Mar 2026 08:29:49 GMT

Kuhn showed that science does not advance smoothly. It lurches between paradigms, with long periods of 'normal science' interrupted by disruptive revolutions. Engineering follows the same pattern, and understanding it can save your career.

The Scientific Method in Engineering Practice

Wed, 18 Mar 2026 08:29:49 GMT

Engineers use the scientific method every day without calling it that. Debugging is hypothesis testing, design reviews are peer review, and every test plan is an experiment. Understanding this connection makes you better at all three.

Technology, Society, and Unintended Consequences

Wed, 18 Mar 2026 08:29:49 GMT

The engineers who designed the automobile intended personal transportation. They did not intend suburbs, oil wars, or climate change. Every technology has consequences beyond its original purpose. Understanding these cascading effects is essential for responsible engineering.

What Makes Something Scientific?

Wed, 18 Mar 2026 08:29:49 GMT

Sensor Fusion and State Estimation

Wed, 18 Mar 2026 08:29:47 GMT
