How Math Helps Us Map The World

It’s easy to take maps for granted. After all, most of us have a pretty good map in our pockets at all times, ready to show us how to get anywhere on the globe. But to make a map useful, you have to decide what to keep in and what to leave out—and, most importantly, which mathematical equations to use. Beyond navigating from point A to point B, math and maps come together for a wide variety of things, like working out the most efficient route to deliver packages, calculating the depth of the ocean floor, and more.

Host Ira Flatow is joined by Paulina Rowińska, mathematician and author of Mapmatics: A Mathematician’s Guide to Navigating the World, to go on a journey through the math at the heart of all kinds of maps.
