Nuts and Bolts: Seven Small Inventions That Changed the World (in a Big Way)

Product Information

Agrawal ends by discussing the desperate need for reuse and recycling in engineering and architecture, and marshalls some truly frightening numbers to support her argument. Agrawal’s detours into politics – the plight of women in STEM, the use of male physical norms in product design – are less happy. Tracing the surprising journeys of each invention through the millennia, Roma reveals how handmade Roman nails led to modern skyscrapers, how the potter's wheel enabledspace exploration, and how humble lenses helped her conceive a child against the odds. Along the way, she recounts the stories of remarkable scientists and engineers from all over the world, and reveals how engineering has fundamentally changed the way we live. May also contain light spine creasing or a few markings such as an owner's name, short gifter's inscription or light stamp.

So, as engineers, let’s place the good of the planet and its inhabitants at the heart of our work,” Agrawal concludes, with a glibness that would be funny if it were not so trying.So Cochrane did what any enterprising engineer’s daughter would do – and invented the dishwasher, “a large, rectangular wooden box, with a slew of cranks, spinning gears, and wheels on one side, into which a cage full of dirty dishes disappeared, only to reappear minutes later, clean, as if washed by hand. Agrawal 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 clarify complex technical principles. So, while Cochran’s dishwasher sits at the heart of the discussion of wheels, the chapter ends with a stellar flourish, describing the four 100kg gyroscopes, spinning 6,600 times a minute, whose angular momentum stabilises the International Space Station in Earth orbit. Another of her subjects – string – helped in a similar way, although this was a technology we could entangle and wind to bind a shard of flint to an axe handle, or adapt into products as diverse as clothing and guitar strings.

At the end of the Second World War The British Intelligence Objectives Subcommittee (BIOS) and other Agency personnel inspected German factories, laboratories, industries, etc, to scrutinise documents and interrogate or interview the directors, scientists, engineers, etc to obtain technical information that might be of value.In Nuts and Bolts, award-winning Shard engineer and broadcaster Roma Agrawal deconstructs our most complex feats of engineering into seven fundamental inventions:the nail, spring, wheel, lens, magnet, string and pump. The idea that small and simple things can be big and complex things in disguise is one that’s fascinated novelists for centuries.

As frameworks for expressing the central ubiquity of engineering in our everyday life go, ‘Nuts and Bolts’ hits the nail on the head. But just like the algorithms that power the integrated circuits in our smartphones, they’re a hidden technology, literally holding everything together.From the physics behind both Roman nails and modern skyscrapers to rudimentary springs that inspired lithium batteries, Agrawal shows us how even the most sophisticated items are built on the foundations of these ancient and fundamental breakthroughs in engineering. Tracing the surprising journeys of each invention through the millennia, Roma reveals 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. Her first book, BUILT (2018) won an AAAS science book award and has been translated into eight languages.

The nail, along with its derivatives – such as the rivet, screw and bolt – meant that we could expand our horizons by joining things together. While it’s tempting to think of ‘Nuts and Bolts’ as an examination of old-fashioned things relegated to rusty tobacco tins in sheds, it’s also worth keeping in mind that the phrase ‘nuts and bolts’ has passed into our everyday language to signify what’s really important about any situation. Roma has given talks to thousands at universities, schools and organisations around the world, including TEDx.No good asking Kwolek who, by her own account, “was fortunate that I worked under men who were very much interested in making discoveries and inventions. 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.
