About Nuts and Bolts By Roma Agrawal

Smartphones, skyscrapers, spacecraft. Modern technology seems mind-bogglingly complex. But beneath the surface, it can be beautifully simple.

Eye-opening and engaging, Nuts and Bolts reveals the hidden building blocks of our modern world, and shows how engineering has fundamentally changed the way we live.
