Description

Explore the life-changing magic of trigonometry with Matt Parker, stand-up mathematician and No. 1 bestselling author of Humble Pi Why can no two people ever see the same rainbow What happens when you pull a pop song apart into pure sine waves and play it back on a piano Why does the wake behind a duck always form an angle of exactly 39 degrees 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. In Love Triangle, stand-up comedian, ex-maths teacher and Sunday Times number one bestselling author Matt Parker is on a mission to prove why we should all show a lot more love for triangles, along with the useful trigonometry and geometry they enable. To make his point, he uses triangles to create his own digital avatar, survive a harrowing motorcycle ride, cut a sandwich into three equal parts, and measure tall buildings while wearing silly shoes. But soon these hare-brained experiments begin to reveal a genuinely important truth- triangles are the hidden pattern beneath the surface of the contemporary world, used in everything from GPS to CGI via Spotify streaming, the play button and your best mate's triangle tattoo. Join Matt Parker as he demonstrates why there's more to triangles than Pythagoras and SOHCAHTOA. Triangles are everything and everything is triangles.

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. Youll use triangles to understand Einsteins 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 -- Tom Calver * Sunday Times *
Matt Parker is a real nerds nerd... but were in safe hands here as we range from those curvy walls of glass that architects seem to love, to why everyone sees a different rainbow. A funny and often surprising guide to the history of triangles and the applications (both practical and highly impractical) of trigonometry -- Tim Harford * Financial Times *
I felt well looked-after, and handled with saint-like patience... Parker has a fine old time with his material, and only a curmudgeon could fail to be charmed by his willingness to call the elongated pentagonal gyrocupolarotunda a dumb shape, or Herons 2,000-year-old formula for finding the area of a triangle stupid. Nor, in the latter case, is he wrong. Four stars -- Simon Ings * Telegraph *
The maths he expounds so expertly and so clearly is always fascinating -- Nick Rennison * Mail on Sunday *
Very funny... When it clicks, it is glorious -- Chris Stokel-Walker * New Scientist *
Despite dealing with what might be familiar concepts, Love Triangle shows that geometry and trigonometry can pop up in exciting and unexpected places. From cosmology to skateboarding, Parker argues that triangles underpin both the epic and the everyday. The book, which is funny and accessible, would also be suitable for keen teenage readers -- Katherine Skipper * Physics World *
Move over Euclid. Its Parker Time. Love Triangle is a blissful blend of pure science and pure merriment. Edifying, entertaining, excellent! -- Alex James
Matt Parker is unique: he's made me laugh about math many times by showing just how weird it can get. He's also made me cry about math by showing how transcendently beautiful it is -- Adam Savage
Fine. Triangles are now my favourite shape -- Hannah Fry
The author has a gift for making somewhat tedious topics not only comprehensible and absorbing, but also great fun... Parkers tireless enthusiasm, light touch, and inviting manner make for a reading experience akin to a visit to Epcot Center, led by a guide in possession of childlike wonder in addition to adult acumen and humor. The author never gets mired in the weeds, even as he manages to cover a tremendous amount of detailed information, aided by illustrations that feature appealing captions running the gamut from simple to complex. A rare book about math sure to make you smile, despite your feelings about the subject. Once again, Parker measures up * Kirkus *
