I think the ultimate engineering project is to learn how to use light as power.

Einstein -- he's one of my heroes. ... He brought all sorts of creative ideas to this planet, and he had a lot of mediocre minds working against him --- but if you're going to accomplish that much, you've got to be challenged. I'm sure he was challenged in a lot of ways, but he managed to steer clear of it. No one ever hated him. You'd think in a position like that you could become bitter, you could become a jerk, and you'd have every right to be that way. But even still to be able to stay a nice guy, and end up having a reverberation like that ... that's incredible.
