    Roma Agrawal

    Formats & Editions

    Shard engineer Roma Agrawal deconstructs our most complex inventions into seven fundamental objects: the nail, spring, wheel, lens, magnet, string and pump._____________'Delightful' TIM HARFORD, FINANCIAL TIMES

    'Appeals to the nerdy side of just about all of us... a great book to give' JANE GARVEY

    'Splendid. Clearly written, elegantly structured full of facts you are unlikely to chance on anywhere else' DAILY MAIL

    *SHORTLISTED FOR THE ROYAL SOCIETY SCIENCE BOOK PRIZE * A TIMES BOOK OF THE YEAR*

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

    Tracing their journeys through the millennia, she shows us how handmade Roman nails led to modern skyscrapers, how the potter's wheel enabled space exploration, and how humble lenses helped her conceive a child against the odds. 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.

    'A wonderful book' MARK MIODOWNIK

    'A masterclass in storytelling' JESS WADE

    'A riveting love letter to the small, wonderful, and mundane things that make the modern world.' ROMAN MARS

    Praise for Nuts and Bolts

    • 'A wonderful book. A fascinating tour that brings to life the springs, ratchets and fibres that makes up the machines of our modern age'

    • There is passion for engineering on every single page. Roma Agrawal has a special skill of reawakening that part of us that simply wants to understand how the built world works, and to dream of creating our own machines.

    • A masterclass in storytelling. Agrawal is the perfect narrator: her curiosity, technical knowledge and excitement fill every page.

    • Essential reading for budding engineers, young and old.

    • Inside this wonderfully engaging book is a profound message: that so much of technology comes from ingenious reiterations of just a few innovations in engineering... Roma Agrawal brings these inventions vividly to life.

    • Fascinating stories behind the humble devices that make our human world work, told with an engineer's infectious excitement and enthusiasm for detail.
