One was Roscoe Gilkey Dickinson. He had got his doctorate in physical chemistry — x-ray crystallography — in 1920. He was the first person to get a Ph.D. from California Institute of Technology. And he was continuing with x-ray crystallography, determining the structure of inorganic crystals. After I had accepted appointment as a graduate student at California Institute of Technology, A.A. Noyes, the head of the division of chemistry and chemical engineering, wrote to say that he had decided I should work with Roscoe Dickinson on determining the structure of crystals. This was really extremely fortunate for me, in my opinion. I don’t think that there was any field that was more suited to my interests, and I don’t really know why Dr. Noyes selected me out of eight or ten new graduate students to do x-ray crystallography. Dickinson had a remarkable mind. He was a very careful investigator and thinker, a very logical thinker. When he was teaching me x-ray crystallography, he also taught me to ask at each stage in the argument, “What assumptions are being made? How reliable is the conclusion that you draw? What chance is there that one of the assumptions you have made is not correct?” “You should recognize,” he said to me, “that there is in almost every investigation a lack of complete rigor. You should understand just how reliable the arguments are that you are presenting.

Actually, I started falling in love with the films of Brian De Palma. He was the first filmmaker I ever loved, he always made genre films. They touched me more, they felt warm, and human, and unsettling. There was always his vision behind them.

Most scientists do. Of course there are the classical figures. I might talk about Einstein a little bit, for example. Now, when I was in college, I was taking my second course in physics, I remember very well, and it had a chapter on relativity. And I took this relativity on a vacation in the mountains; my family went with me. And I remember very well sitting on a rock up in the hills there overlooking a stream, reading this relativity derivation. And it was just very exciting and interesting. It was a strange new world, relativity. I even thought I had found where Einstein made a mistake. And I went back for lunch, and I thought about it, came back. And I said, “No, he was right after all,” but it was still very exciting. To see a completely different kind of idea and world from what one’s normal intuition shows. Of course, Einstein was one of the great scientists; I’ve always admired him. I fortunately had a chance to talk with him and interact with him a little bit as well.

The music of the “I Have a Dream” speech is a replication of the music which comes out of the mouths of the African American preacher. Preacher, singer, blues singer, jazz singer, rap person, it is so catching, so hypnotic, so wonderful that, as a poet, I continue to try to catch it, to catch the music.

You're so nice. You're not good, you're not bad, You're just nice. I'm not good, I'm not nice, I'm just right. I'm the witch. You're the world.

One difference between poetry and lyrics is that lyrics sort of fade into the background. They fade on the page and live on the stage when set to music.

But that’s part of the process, isn’t it? Something might not fit in the show. Musicals are — particularly musicals — plays also, but musicals particularly are… the last collaborator is your audience, and so you’ve got to wait ’til the last collaborator comes in before you can complete the collaboration. And when the audience comes in, it changes the temperature of what you’ve written. Things that seem to work well — work in a sense of carry the story forward and be integral to the piece — suddenly become a little less relevant or a little less functional or a little overlong or a little overweight or a little whatever. And so you start reshaping from an audience.

I'm a lazy writer. My idea of heaven is not writing. On the other hand, I'm obviously compulsive about it.

All the best performers bring to their role something more, something different than what the author put on paper. That's what makes theatre live. That's why it persists.

Musicals are plays, but the last collaborator is your audience, so you've got to wait 'til the last collaborator comes in before you can complete the collaboration.
