Quote by Nicodemus Copernicus

"Astronomy is written for those who look at the heavens."

"The Universe is a great living body, of which we are insignificant parts."

"To know that we know what we know, and to know that we do not know what we do not know, is true knowledge."

"I am not so enamored of my own opinions that I disregard what others think."

"The best part of living is knowing you survived."

"The world needs heroes."

"Life is too short to live poorly."

"I'd rather be an optimist and be wrong than a pessimist and be right"
