Quote by Fidel Castro

"A revolution is not a bed of roses."

"Condemn me, it does not matter. History will absolve me."

"The revolution is not an apple that falls when it is ripe. You have to make it fall."

"I am a Marxist-Leninist and will be one until the day I die."

"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!"
