What satellites help to show us is we've actually only found a fraction of a percent of ancient settlements and sites all over the world... It's the most exciting time in history to be an archaeologist.

Scientists use satellites to track weather, map ice sheet melting, detect diseases, show ecosystem change... the list goes on and on. I think nearly every scientific field benefits or could benefit from satellite imagery analysis.

I have a company in the U.K., a performance-capture studio. We're looking to push the boundaries of performance-capture technology in film and video games, but also in live theater, using real-time performance capture with actors onstage, and combining that with holographic imagery.

When you wash your hands, when you make a cup of coffee, when you're waiting for the elevator - instead of indulging in thinking, these are all opportunities for being there as a still, alert presence.
