Quote by Enrico Fermi

"Where are they?"

"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."

"Time waits for no one."

"Time spent with loved ones is never wasted."

"I've been alive for a long time. Long enough to know that you can't trust anyone."

"The past always catches up with you."
