Quote by George Berkeley

"Esse est percipi"

"To be is to be perceived"

"All the choir of heaven and furniture of earth - in a word all those bodies which compose the frame of the world - have not any subsistence without a mind"

"If a tree falls in the forest and no one is around, does it make a sound?"

"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!"
