Quote by Nathaniel Hawthorne

"Happiness is a butterfly, which when pursued, is always just beyond your grasp, but which, if you will sit down quietly, may alight upon you."

"We are all fools and knaves in our own fashion."

"No man, for any considerable period, can wear one face to himself and another to the multitude, without getting bewildered as to which may be true."

"The greatest obstacle to being heroic is the doubt whether one may not be going to prove oneself a fool."

"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!"
