How Was That Built? The Stories Behind Awesome Structures

“Once you read this book, you’ll see the world through different eyes—the eyes of an engineer,” promises this in-depth introduction to structural engineering. Chapters each examine a construction challenge, such as “how to build tall,” “strong,” or “underground.” Anchoring the discussion are detailed case studies of emblematic engineering marvels such as the Brooklyn Bridge, London’s sewers, and Antarctica’s Halley VI research station. Throughout, overviews summarize topics such as “advances in concrete” and “ancient water engineering.” Agrawal packs a lot in, making the read feel dense, but creative comparisons and DIY experiments help clarify engineering principles. Hickey’s pencil-textured illustrations animate edifices and scenes of construction, emphasizing ingenuity. A glossary and an engineers’ gallery enhance the book’s appeal as a reference for budding builders. Ages 6–9. (Aug.)
