Werner Heisenberg — "Science is rooted in conversations."

"The reality we can put into words is never reality itself."

"If a man is to be a good physicist, he must have an intuitive grasp of the physical reality, which can be acquired only by much experience."

"The problems of language here are really serious. We wish to speak in some way about the structure of the atoms. But we cannot speak about atoms in ordinary language."

"Natural science does not simply describe and explain nature; it is part of the interplay between nature and ourselves."

"Only a few know, how much one must know to know how little one knows."
