Stunning foldout pages, panels, diagrams, photographs and Mega Facts boxes make this book a stimulating read for all ages. Mega Structures describes how and why these structures were designed and built. It explains the physics behind the designs, which allows buildings, dams or bridges to rise to incredible heights, withstand enormous pressures, and resist collapse from environmental forces. The book is organized into four sections. (1) Towering Giants: skyscrapers, towers, monuments, offshore platforms. (2) Gigantic Lengths: wide and long, over and under. (3) Massive Monsters and Darkest Depths: stadiums, islands, dams. (4) Darkest Depths: mines, power stations, ice cores.
