The Tacoma Narrows Bridge collapsed in 1940 after an hour of twisting in moderate winds.

The error cost about US$65 million in today ’s dollars and a dog's life.

All engineering calculations are based on models that help scientists and engineers connect data to the real world.

The trick to using models safely is to pick assumptions where the limitations do not ruin their intended use.

While courses often teach young engineers to make assumptions and use models, they rarely focus on these models’ limitations. Helping students develop their engineering judgment can prevent failures like “ Galloping Gertie ” from happening again.
