This footnote in McCullough's *The Great Bridge* blew my mind. As late as the 1880s, we still didn't know how to build bridges! We would put them up, and many would just collapse.pic.twitter.com/6vjfkQ482H

Or to take another example, I think I recall hearing about a failure due to iron becoming brittle in extreme cold, not necessarily something you could predict without a lot of materials science.
Also I have to admit I have no idea how many total bridges there were in the country at the time, or how fast they were going up. So I don't even know the order of magnitude of the failure rate here. Still, forty a year!
Anyway, gotta be a fascinating story here. Definitely will cover this in a future @rootsofprogress post!

So here's an example of a bridge collapse. Diagnosis: the engineer “had not calculated his wind loads accurately”pic.twitter.com/uwtmofMx9U
Terribly complicated? You only have to remember two equations https://www.comsol.com/multiphysics/navier-stokes-equations …
