You've described your inspiration for the maser as a moment of revelation, more spiritual than what we think of as inspiration. Do you believe that God takes such an active interest in humankind?
[The maser] was a new idea, a sudden visualization I had of what might be done to produce electromagnetic waves, so it's somewhat parallel to what we normally call revelation in religion. Whether the inspiration for the maser and the laser was God's gift to me is something one can argue about. The real question should be, where do brand-new human ideas come from anyway? To what extent does God help us? I think he's been helping me all along. I think he helps all of us - that there's a direction in our universe and it has been determined and is being determined. How? We don't know these things. There are many questions in both science and religion and we have to make our best judgment. But I think spirituality has a continuous effect on me and on other people.
That sounds like you agree with the "intelligent design" movement, the latest framing of creationism, which argues that the complexity of the universe proves it must have been created by a guiding force.
I do believe in both a creation and a continuous effect on this universe and our lives, that God has a continuing influence - certainly his laws guide how the universe was built. But the Bible's description of creation occurring over a week's time is just an analogy, as I see it. The Jews couldn't know very much at that time about the lifetime of the universe or how old it was. They were visualizing it as best they could and I think they did remarkably well, but it's just an analogy.
Should intelligent design be taught alongside Darwinian evolution in schools as religious legislators have decided in Pennsylvania and Kansas?
I think it's very unfortunate that this kind of discussion has come up. People are misusing the term intelligent design to think that everything is frozen by that one act of creation and that there's no evolution, no changes. It's totally illogical in my view. Intelligent design, as one sees it from a scientific point of view, seems to be quite real. This is a very special universe: it's remarkable that it came out just this way. If the laws of physics weren't just the way they are, we couldn't be here at all. The sun couldn't be there, the laws of gravity and nuclear laws and magnetic theory, quantum mechanics, and so on have to be just the way they are for us to be here.
Some scientists argue that "well, there's an enormous number of universes and each one is a little different. This one just happened to turn out right." Well, that's a postulate, and it's a pretty fantastic postulate - it assumes there really are an enormous number of universes and that the laws could be different for each of them. The other possibility is that ours was planned, and that's why it has come out so specially. Now, that design could include evolution perfectly well. It's very clear that there is evolution, and it's important. Evolution is here, and intelligent design is here, and they're both consistent.
