Thoughts on Love Triangle: How Trigonometry Shapes the World

Overview

An ode to triangles, the shape that makes our lives possible Trigonometry is perhaps the most essential concept humans have ever devised. The simple yet versatile triangle allows us to record music, map the world, launch rockets into space, and be slightly less bad at pool. Triangles underpin our day-to-day lives and civilization as we know it.
In Love Triangle, Matt Parker argues we should all show a lot more love for triangles, along with all the useful trigonometry and geometry they enable. To prove his point, he uses triangles to create his own digital avatar, survive a harrowing motorcycle ride, cut a sandwich, fall in love, measure tall buildings in a few awkward bounds, and make some unusual art. Along the way, he tells extraordinary and entertaining stories of the mathematicians, engineers, and philosophers—starting with Pythagoras—who dared to take triangles seriously. This is the guide you should have had in high school—a lively and definitive answer to “Why do I need to learn about trigonometry?” Parker reveals triangles as the hidden pattern beneath the surface of the contemporary world. Like love, triangles actually are all around. And in the air. And they’re all you need.

Matt Parker knows their way around righting triangle puns

This is the third book I read by Matt Parker and my first owned (signed!) from them! I’ve been watching them on YouTube (on Numberphile & Matt’s own channel Stand-up Maths) and I can feel the personality come out of the page. (But maybe that’s because I’ve watched their videos for so long.)

It really goes about showing that triangles are really everything (and ‘every triangle is a love triangle when you love triangles’).

I think this is book (& really all that Matt Parker does) is so entertaining for a casual mathematical audience. I do hope all the silliness and seriousness they bring never ends.

Love the continuing ‘gag’ of using unconventional page numbering– making it not easy to track
