Werner Heisenberg Quotes

The uncertainty principle refers to the degree of indeterminateness in the possible present knowledge of the simultaneous values of various quantities with which the quantum theory deals; it does not restrict, for example, the exactness of a position measurement alone or a velocity measurement alone.

Werner Heisenberg

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

Werner Heisenberg

What we observe is not nature itself, but nature exposed to our method of questioning.

Werner Heisenberg
