"The history of science is science itself;..." - Quote by Johann Wolfgang Von Goethe

“The world is so full of simpletons and madmen, that one need not seek them in a madhouse.”

“Man's restlessness makes him strive.”

“The greater the knowledge, the greater the doubt.”

“I have become an obstinate heretic in the eyes of my colleagues. Momentary success carries more power of conviction than reflections upon principles.”

“You have heard of the new chemical nomenclature endeavored to be introduced by Lavoisier, Fourcroy, &c. Other chemists of this country, of equal note, reject it, and prove in my opinion that it is premature, insufficient and false. These latter are joined by the British chemists; and upon the whole, I think the new nomenclature will be rejected, after doing more harm than good. There are some good publications in it, which must be translated into the ordinary chemical language before they will be useful.”

“Concepts which have proved useful for ordering things easily assume so great an authority over us, that we forget their terrestrial origin and accept them as unalterable facts. They then become labeled as 'conceptual necessities,' etc. The road of scientific progress is frequently blocked for long periods by such errors.”

“The Long March The Red Army is not afraid of hardship on the march, the long march. Ten thousand waters and a thousand mountains are nothing. The Five Sierras meander like small waves, the summits of Wumeng pour on the plain like balls of clay. Cliffs under clouds are warm and washed below by the River Gold Sand. Iron chains are cold, reaching over the Tatu River. The far snows of Minshan only make us happy and when the army pushes through, we all laugh. October 1935”

“History is a record of perpetual wars, but we are now trying to make new history.”

“By the year 1670, wooden chimneys and log houses of the Plymouth and Bay colonies were replaced by more sightly houses of two stories, which were frequently built with the second story jutting out a foot or two over the first, and sometimes with the attic story still further extending over the second story.”
