Quote by Karl Marx

"The philosophers have only interpreted the world in various ways; the point is to change it."

"Workers of the world, unite; you have nothing to lose but your chains."

"The ruling ideas of each age have ever been the ideas of its ruling class."

"Religion is the opium of the people."

"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!"
