"The effort to build a space-faring civilization, that's worth doing."

"Whatever the ups and downs of the details which we learn or unlearn, the speak of science only increases."

"I think it is good merely to emphasize again that, in physics, you don't have to go around making trouble for yourself—nature does it for you."

"Science helps us understand the world."

"I've witnessed the birth of science, and it continues to amaze me."

"I'm something of a scientist myself."

"The fusion process is self-sustaining now!"
