I first became aware of Charles Darwin and evolution while still a schoolboy growing up in Chicago. My father and I had a passion for bird-watching, and when the snow or the rain kept me indoors, I read his bird books and learned about evolution.

One-third of all female infertility is the result of blocked fallopian tubes. If fertilization could be done in the lab and then the fertilized egg implanted in the womb, it would get around that problem. Millions of women who cannot have children would suddenly be able to.

I never could read science fiction. I was just uninterested in it. And you know, I don't like to read novels where the hero just goes beyond what I think could exist. And it doesn't interest me because I'm not learning anything about something I'll actually have to deal with.

Indeed, the history of 20th century physics was in large measure about how to avoid the infinities that crop up in particle theory and cosmology. The idea of point particles is convenient but leads to profound, puzzling troubles.

Science would lead you to a more interesting life than something else.

I didn't understand how you could be an actor if you didn't also study philosophy and study political science, astronomy. And also just go out and live life and have experiences.
