Quote by William Butler Yeats

"The best way to live is to act as if you are already dead."

"Do not wait to strike till the iron is hot; but make it hot by striking."

"There are no strangers here; only friends you haven't yet met."

"How can we know the dancer from the dance?"

"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!"
