"A riveting love letter to the small, wonderful, and mundane things that make the modern world." —Roman Mars
A structural engineer examines the seven most basic building blocks of engineering that have shaped the modern world.
Some of humanity’s mightiest engineering achievements are small in scale—and, without them, the complex machinery on which our modern world runs would not exist. In Nuts and Bolts, structural engineer Roma Agrawal examines seven of these extraordinary elements: the nail, the wheel, the spring, the magnet, the lens, the string, and the pump.
Tracing the evolution from Egyptian nails to modern skyscrapers, and Neanderthal string to musical instruments, Agrawal shows us how even our most sophisticated items are built on the foundations of these ancient and fundamental breakthroughs. She explores an array of intricate technologies—dishwashers, spacesuits, microscopes, suspension bridges, breast pumps—making surprising connections, explaining how they work, and using her own hand-drawn illustrations to bring complex principles to life.
Alongside deeply personal experiences, she recounts the stories of remarkable—and often uncredited—scientists, engineers, and innovators from all over the world, and explores the indelible impact these creators and their creations had on society. In preindustrial Britain, nails were so precious that their export to the colonies was banned—and women were among the most industrious nail makers. The washing machine displayed at an industrial fair in Chicago in 1898 was the only machine featured that was designed by a woman. The history of the wheel, meanwhile, starts with pottery, and takes us to India’s independence movement, where making clothes using a spinning wheel was an act of civil disobedience.
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.

Memmo's summaries are gold before exams. I don't have to re-read 800 pages two weeks before — just the important parts.
The AI chat has saved me the night before an exam more than once. I just keep asking until I get it — no waiting on a study group to reply.
The quizzes hit exactly what I need to know. Memmo tracks what I get stuck on — so I only practice what's worth it.
Flashcards with spaced repetition are magic. Memmo knows when I'm about to forget something and brings it back.
The AI podcasts are my favorite. I listen on my way to school and get a recap without sitting at a computer.
