Smoother surfaces usually mean less resistance—but not always. A recent Tohoku University study found that microscopic distributed roughness reduced measured drag on a streamlined wind-tunnel model under specific transitional-flow conditions, offering engineers a fascinating reminder that even reliable design rules can have carefully engineered exceptions.

Fazlur Rahman Khan changed the way engineers design tall buildings. Known for pioneering tube structural systems, Khan helped make modern skyscrapers more efficient, economical, and structurally practical, leaving a lasting legacy in civil and structural engineering.

Engineering shaped the early United States long before universities recognized it as an academic discipline. This article explores how practical problem-solving evolved into formal education, and how the Morrill Act and growing infrastructure demands finally pushed institutions to legitimize engineering.

Rudolf Diesel revolutionized mechanical engineering by developing a high-efficiency engine based on compression ignition. His work, rooted in thermodynamic principles, transformed global transportation and power systems. This article explores the engineering behind the diesel engine and its lasting impact.

The Alaska Highway was not a failure, nor was it a disaster. It was an extraordinary engineering response to extraordinary circumstances. Built rapidly under wartime pressure, it achieved its strategic objective while revealing the limits of contemporary construction knowledge.

For American Professional Engineers, Japan’s experience offers both technical insight and a broader professional lesson. Earthquake resilience is not achieved through a single device, material, or calculation method. It emerges from a consistent philosophy that accepts movement as inevitable and focuses on managing it intelligently. As seismic risk awareness continues to expand beyond traditional high-risk regions in the United States, Japan’s engineering practices provide a compelling example of how performance-based thinking, system integration, and long-term planning can shape safer and more resilient communities.
