Hello and welcome to sleep money, your guide to the business and finance news of the week, but honestly, we're going to do

the business and finance news of the past six millennia here on this one. This is a really big

picture show. I'm Felix Hammond of Axios. I'm here with Emily Peck of Axios. Hello.

I'm here with Elizabeth Spires of the New York Times and Slate and places like that.

Hello. But most excitingly, I'm here with Elizabeth Spires of the New York Times and Slate and places like that. Hello.

But most excitingly, I'm here with Ed Conway. Ed, welcome.

Hi.

Ed, who are you? Introduce yourself and tell us about this incredible new book that just came out.

Well, I'm just a guy. I'm the economics editor.

Actually, I'm economics and data. Now they added a bit to my title. I'm the economics and

data editor at Sky News in the UK. I write, you know, columns and things for a few newspapers

over here. And I've written a book called Material World. And it's, I guess, oh, God,

where to begin. It's all about the world we inhabit and told through six substances without

which we all be in big trouble. At least one of which is literally necessary for human existence,

but all of which are necessary for contemporary human existence. We're going to dive into everything from salt taxes to concrete, to glass, to lithium, to copper mines,

and how profoundly sensual all of these things are to our quotidian existence, notwithstanding the fact that

we almost never think about them. All of this, it really is an amazing show. You have to listen to

this one. It's all coming up on Slate Money.

There are days when you're hungry for McDonald's. Then there are days when you're Big Arch hungry for McDonald's.

You'll get to know the difference.

New Big Arch for Big McDonald's hunger.

Until 9th of September, from 11 AM,
