Love Triangle

The Life-changing Magic of Trigonometry

Summary

Brought to you by Penguin.

Why do mobile phones work when you're on a train? What happens when you pull a pop song apart into pure sine waves and play it back on a piano? And what did mathematicians have to do with the great pig stampede of 2012? The answer to each of these questions can be found in the triangle.

Humans have been using triangles for thousands of years to build structures, measure the earth, make music, paint vanishing points, pot snooker balls and much, much more. But trigonometry is not a thing of the past - triangles underpin all of modern data technology. When someone Snapchats a photo, the light travels into the camera as electromagnetic sine waves, Fourier analysis compresses the image and then trigonometry is used to send the data to someone else's phone; when you listen to a track on Spotify, triangles remove the sounds which a human ear can't perceive and reassemble the song so that it's small enough to stream. Triangles are the hidden pattern beneath the surface of the contemporary world.

Join Matt Parker, stand-up comedian and author of the first ever maths book to be a No. 1 bestseller, as he uncovers the secrets of trigonometry and shares extraordinary stories about the mathematicians, philosophers and engineers who dared to take triangles seriously.

Reviews

  • This book is an attempt to rescue trigonometry from the bounds of boredom... Parker, who was born in Australia, is maths royalty... Parker is funny, likeable and aware enough of his audience to carry them along. And those who persevere will end up smarter than they were when they started it. You’ll use triangles to understand Einstein’s relativity, and end up at the stark realisation that, at the quantum level, matter — you, I, this book — is all just a set of triangles
