Did you ever want to be a time traveler? To go back in time to see the dinosaurs? Or to visit the future to see how something turned out? Well, I am a time traveler. And in the next few minutes, I want to show you how time travel is useful in innovation创新. Now when I say I'm a time traveler, I don't mean I'm from the past or from the future, future, future. No, I'm from right now. But I've traveled thousands of years into the past by studying Latin in ancient Greek.
And in my work as a geologist地质学家 and geophysicist, I went even farther back millions and billions of years. Today, I work into the future as a space technologist, applying the lessons of yesterday and today to the problems of tomorrow. Many of the things we can't do in space yet are things we've been doing on Earth for a very long time.
