Hey, a quick reminder to subscribe to the show, so you get new episodes as soon as they're available.

That will be especially useful tomorrow. We're bringing you an update on the latest coronavirus

news and science, which we'll be doing more often in the coming weeks as well. Okay? Okay.

You're listening to Shortwave from NPR.

Maddie's if I hear with a math problem, don't be scared. Say you're trying to build a fence

50 feet long and you need to post every 10 feet. How many posts do you need?

Got your answer? Okay, just hold that in your head for a second while we introduce Matt Parker.

Oh, hey, can you hear me coming through? Yeah, Matt's kind of like, can you hear me?

Part comedian. Hey, Maddie, yes I can. Part math nerd. Matt, how should we describe what you do?

That's a great question. I go with, you sound like my accountant. I go with, I have stand-up

mathematician. So I'm probably a mathematician first in a comedian second. Matt's got a big

YouTube channel. He's an author. He works with schools all trying to blend math and comedy.

Here is a timely example. So I've done stuff like I've used a pendulum. In fact, I swung a baked pie

from a piece of string and the way you calculate how long something takes to swing back

and forwards. That calculation has the mathematical number, pie in it.

Pie, of course, is the ratio of a circle's circumference to its diameter, which calculates to

3.141592653589. We love it because it appears in unexpected places. You'll be doing some

completely unrelated mathematics and suddenly pies there. And we celebrate pie day every year

on March 14th. But the kind of pie we're focused on today is humble pie. The kind you eat when

you make a mistake, which brings us back to that math problem in a 50-foot fence,

opposed every 10 feet. How many posts? And people listening are now thinking, oh okay, 50 feet,

one every 10 foot, then there must be five. We can all divide 50 by 10. Actually, you need six.
