When a giant bridge collapses, a gas explosion blows up a building, or a major dam bursts, it’s hard not to wonder how things could have gone so catastrophically wrong. According to Grady Hillhouse, those failures are the defining force of engineering, where the most important lessons were learned the hard way.With the same engaging and accessible approach that make his YouTube videos so popular, Hillhouse breaks complex failures down into their component parts, showing how poor judgment and willful ignorance can play just as big a role as an errant measurement or faulty component. The fascinating behind-the-scenes stories of history’s greatest structural breakdowns, from the Johnstown flood and the Tacoma Narrows bridge collapse to the Leaning Tower of Pisa, reveal how engineers learned from their mistakes and developed the core principles that keep buildings standing today.Not all of us will design a building or lay out an electrical grid, but thinking like an engineer can help us spot weak links, respect margins, and value hard truths over wishful thinking. Disasters by Design celebrates human resilience and our extraordinary capacity for progress.
