Very brave.

Yes, it was.

And I went to the premiere at Haberfield and I'd interviewed the young people who were on the stage and done rehearsals.

And I asked, how do you feel about being Michael Faraday or Emily du Châtelet, you know, a French woman?

Because each of these names was connected with a particular part of the equation.

And they said they were terribly excited.

I said, isn't it too abstract for you?

No, no, these are very important people and now we remember them because we're being them.

And it was opened by Michelle Simmons, Australian of the Year and quantum computing fame.

And there was a standing ovation.

It really worked wonderfully.

So how did this latest performance in the last few days work?

Yes, Noel Pearson is director of the Cape York Partnership, good to great schools, north of Cairns.

So much science going on up there, and yes, 46% of Australia is in the tropics, which is why Susan Lawrence is so busy with international connections, looking after the forests in the north.

She's Professor of Tropical Ecology at James Cook University in Cairns.

Could you take me to the Dane Tree and go to the place where you've got this huge crane and whether you actually go up in it?

And you see the canopy there.

And when you look down, what are you actually looking for?

What do you see as a scientist?

How far up in the sky are you?
