It's Friday, September 30th, 2016, and you're listening to Inquiring Minds.

I'm Indravis Gontes.

Each week, we bring you a new, in-depth exploration of the space where science, politics, and society collide.

We endeavor to find out what's true, what's left to discover, and why it all matters.

You can find us online at motherjones.com slash inquiring minds or inquiringshow.com.

You can also find us on Twitter at inquiring show and Facebook. And you can subscribe to the show on

iTunes or any other podcasting app. This week's episode is sponsored by Decode DC, the podcast that gives you an honest look into how politics affects your life.

The host of Decode DC, Jimmy Williams, you've got to hear this guy.

He's worked in politics on both sides of the aisle as a lobbyist.

He really knows this stuff, and he's taking all

that experience and explaining how things really work inside and outside of Washington. Decode DC is a

smart, surprising. It challenges the conventional wisdom, like in their recent episode about salt

on how and why the government decided to push food makers to reduce sodium levels.

Check it out. I did. I think you'll love it. That's Decode DC available on iTunes or any

other podcasting app. My co-host Kishore is taking this week off after he did such a great

job covering sexual harassment in science last week.

If you haven't checked out that show, please do.

And this week, I had the pleasure of speaking to one of my favorite scientists and science

communicators.

Coming back on the show is Stuart Firestein.

He's a professor and former chair of the Department of Biological Sciences at Columbia.

And his previous book, Ignorance, told us about how science is not about knowledge, but rather about what we don't know.
