Quote by Pierre-Simon Laplace

"I had no need of that hypothesis."

"The weight of evidence for an extraordinary claim must be proportioned to its strangeness."

"What we know is not much. What we do not know is immense."

"If we ought to have a fear of anything, we ought to have a fear of want of knowledge rather than of scepticism."

"Success comes to those who never give up."

"Success is measured by happiness, not money."

"You make your own luck in this world."

"You have to be organized to be successful in anything."
