Introduction

Structural engineer Roma Agraval visits Google to discuss her book, Nuts and Bolts. The book takes readers on a deep dive into the seven most basic building blocks of engineering that have shaped the modern world. Shaddi constructs our most complex feats of engineering into seven fundamental inventions- the nail, spring, wheel, lens, magnet, string and pump. Together they have enabled humanity to see the invisible, build the spectacular, communicate across vast distances and even escape our planet.
