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."

"I believe in working hard for what you want."

"Never underestimate the power of determination."

"I don't need a reason to fight."

"The most important thing is the mission. Nothing else matters."
