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."

"Face your fears with courage."

"You can't live your life in fear."

"Snakes. Why'd it have to be snakes?"

"Fear is just another obstacle to overcome."
