Ah, Benny's parents, thanks for coming.

Hiya.

So, Benny has really blossomed this term.

You're telling me, he outgrew his bike. We sold it, on eBay.

Oh, that's not quite what I meant.

It's free to sell on there?

Free to sell?

Easy too. Sold Benny's bike, your guitar, my jacket.

You sold my guitar?

Shall we talk about Benny?

When it's this easy to sell for free, you can't help but say when it's eBay.

Things people love. T's and Cs apply, exclusive vehicles.

Welcome to Science Talk, the weekly podcast of Scientific American for the seven days starting November 15th.

I'm Steve Murski. This week on the podcast, some

small talk in multiple senses and a little poetry. Last week I attended the World Science Forum here

in New York City, and we'll have some discussion about that. On Sunday, I went to hear a lecture on

poetry and science from chemist Roald Hoffman, and we'll have more from him later.

Plus, we'll test your knowledge about some science in the news.

First, the World Science Forum, Scientific American Editor-in-Chief John Rennie was there, too,

and I asked him about the event.

Hi, John. How are you?

Hi, Steve.
