Skyscrapers Robyn Hardyman

Humans have been scraping the sky much longer than most people think. In this exciting volume, readers will explore a comprehensive history of humanity's most vertically ambitious architecture and learn the fascinating geometry that makes such engineering possible. They'll also investigate technologies these man-made heights require, such as escalators, elevators, weather-resistant materials, and more. Dizzying photographs will amaze even reluctant readers, and a fun map invites interaction. Complete with a hands-on engineering activity, this jaw-dropping volume is an essential addition to any library and classroom.
