When I was a child growing up in Maine, one of my favorite things to do was to look for sand dollars on the seashores of Maine, because my parents told me it would bring me luck. But you know, these shells, they're hard to find. They're covered in sand. They're difficult to see.

Archaeology holds all the keys to understanding who we are and where we come from.

It's absolutely critical, you know, to train young men and women not just to find sites, but also to protect sites, especially in the wake of the Arab Spring. There's been significant site-looting in Egypt and elsewhere across the Middle East.

WorldView-3 goes into the mid-infrared wavelength, allowing you to see very subtle geological differences on the sites at a 0.4-metre resolution.

The digital camera is a great invention because it allows us to reminisce. Instantly.

The younger generation is surrounded by the Internet, apps, and video games. But somehow, my books make them read.

I can't say I am totally up to date with the latest technology, but at the same time, I would say that I am very good at working out how to use technical items.

I see film as a real opportunity to examine the human condition. No matter where the technology goes in the future, the basics don't change. Storytelling is a primitive tribal function. The elders sat around the fires and told these stories as a way to pass on the 'dos' and the 'don'ts.' That will never change.
