Roma Agrawal’s best known feat is London’s towering Shard, so it’s fair to say she knows a thing or two about engineering. As a writer and broadcaster, she also knows how to explain complicated concepts clearly. Join her as she discusses the complex feats of engineering she deconstructs in Nuts and Bolts: Seven Small Inventions That Changed the World, and how they all rely on seven fundamental inventions: the nail, spring, wheel, lens, magnet, string and pump. Together, these inventions have enabled humans to construct stunning buildings, communicate across vast distances, and even explore other planets. You’ll leave marvelling at simplicity behind some of the most powerful and spectacular inventions of our time. Agrawal talks to Georgina Godwin, journalist and Books Editor for Monocle 24.
