Theyre huge books, and normally youd go, One of these will last me a whole winter.

But I was like, No, I want to not do things.

I want to go home in the evening and finish reading.

I think a lot of people talk about the books like that.

Did you become interested in the science ofGame of Throneswhile you were reading the books or watching the show?

[But] then you start thinking, We dont have any animals that breathe fire.

Its this really cool trait that dragons have, but we dont see that anywhere in the actual world.

So where is that coming from?

You just start having these questions and thinking about how much of this is possible.

How did you approach the research?

Were you trying to watch the show and note what might have a basis in science?

Like swords made out of meteorites.

People actually did that.

They didnt have the technology to smelt iron and steel.

They didnt have furnaces to do that.

They were like, Theres this interesting stuff that keeps falling in the desert.

Tutankhamen had all these things in his tomb made out of meteorite.

I was trying to find interesting questions to approach them with, see where that went.

In the [most recent season] finale, theres a massive explosion.

We were watching the clip, and I was going, At this point whats going on here?

Was there anything you brought up where a scientist said, Theres no real scientific basis here?

Some of the stuff seems like its mostly magic.

Are there any other shows youd like to delve into, science-wise?

Westworldraises lots of questions: Are computers self-aware?

If we create this thing that looks like a human being, how should we treat it?

What kind of rights should we give it?

Not just science questions, but ethical ones.

I think that stuff is pretty fascinating.
