“I think it's helpful to know how sunsets work. I don't buy the romantic notion that scientific understanding somehow robs the universe of its beauty, but I still can't find language to describe how breathtakingly beautiful sunsets are--not breathtakingly, actually, but breath-givingly beautiful. All I can say is that sometimes when the world is between day and night, I'm stopped cold by its splendor, and I feel my absurd smallness. You'd think that would be sad, but it isn't. It only makes me grateful.”
