"We come now to the question: what..." - Quote by Albert Einstein

Already the distance-concept is logically arbitrary; there need be no things that correspond to it, even approximately.

“One ought to be ashamed to make use of the wonders of science embodied in a radio set, the while appreciating them as little as a cow appreciates the botanic marvels in the plants she munches.”

“Reality is merely an illusion, albeit a very persistent one.”
“Whereas the man of action binds his life to reason and its concepts so that he will not be swept away and lost, the scientific investigator builds his hut right next to the tower of science so that he will be able to work on it and to find shelter for himself beneath those bulwarks which presently exist.”
“The great virtue of my radicalism lies in the fact that I am perfectly ready, if necessary, to be radical on the conservative side.”
