Quote by Friedrich Engels

"The oppressed are allowed once every few years to decide which particular representatives of the oppressing class are to represent and repress them."

"All that is solid melts into air, all that is holy is profaned."

"The working men have no country."

"History repeats itself, first as tragedy, second as farce."

"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!"
