How to pronounce “strog” in English

Duncan Watts and Steve Strogatz, set out to solve this small-world problem.

- Watts and Strogatz tested their model on the worm's neural network.

But when Watts and Strogatz ran the calculations, they found the average degrees of separation between any two neurons was just 2.65.

That's my Trampoline Stroganoff story.

Watts and Strogatz had what they call a Small World Graph, which is a parameterized graph between a completely regular graph on one

But what interests Steve Strogatz, a mathematician at Cornell University, is that there are places in the world-- Robert Krulwich: Not here, but in Southeast Asia, in Malaysia or Thailand--

- Now, in Watts and Strogatz's model, they looked at 1,000 nodes, but if you apply their model to the eight billion people on Earth,

- In 1998, Watts and Strogatz published their findings in a three-page article in "Nature," and the paper took off.

which is great. Steve Strogatz has a book called "Joy of X," which is a really wonderful ABC of mathematics, starting from counting and building toward some more

That was good. Stroganoff.

Well-- Robert Krulwich: Well, Strogatz said, "There's the occasional sound of the bird." Jad Abumrad: Exactly, and you hear-- So, it's kind of like a word.

- To study this middle ground, Watts and Strogatz imagined a simple regular network of people, or nodes, dotted around a circle,

to 10. But Watts and Strogatz also tracked how clustered the network was.

- Excited about their breakthrough, Watts and Strogatz wanted to test their small-world model on some real-world data, but this was 1996.

- Now, that's a Steve Strogatz problem.

- Back in 1997, Watts and Strogatz investigated just that, using a game called the prisoner's dilemma.

And I said oh, they're called Trampoline Stroganoff actually.

And I think I took a couple more photos after that, me and Trampoline Stroganoff.

They don't actually make sound." Robert Krulwich: Remember also, Strogatz said that this whole event takes place in total silence.

Apparently the web was a small world too, but the strange thing was, it didn't look anything like the small-world network in Watts and Strogatz's model.

What if we put them on a network?" - Well, Watts and Strogatz simulated their own version of the prisoner's dilemma that did just that.

And you know, I'm really, really digging the the smoked chicken stroganoff right now which stroganoff you don't really hear that word
