Thomas Jefferson basically secularized Jesus.

I don't need my name anywhere.

There's no tradition of scientists knocking down the Sunday school door, telling the preacher, That might not necessarily be true. That's never happened. There're no scientists picketing outside of churches.

I try to educate the public and let them make the decisions for themselves.

But to measure cause and effect... you must ensure that a simple correlation, however tempting it may be, is not mistaken for a cause. In the 1990s the stork population of Germany increased and the German at-home birth rate rose as well. Shall we credit storks for airlifting the babies?

When you advance a frontier and you do tomorrow what's never been done today, you have to innovate to make that happen. You become an innovation culture. When I grew up, every time I turned around it was, "Oh, here's the longest bridge or the deepest tunnel or the fastest airplane." And I originally thought that was just kind of like a pissing contest with men with too much testosterone. And then I realized that to make the tallest building you have to innovate. To make the fastest train you have to design the train in a way that it's never been designed before.
