Nature allows only experimental situations to occur which can be described within the framework of the formalism of quantum mechanics

The exact sciences also start from the assumption that in the end it will always be possible to understand nature, even in every new field of experience, but that we may make no a priori assumptions about the meaning of the word understand.

There is a fundamental error in separating the parts from the whole, the mistake of atomizing what should not be atomized. Unity and complementarity constitute reality.

There are things that are so serious that you can only joke about them.

Science no longer is in the position of observer of nature, but rather recognizes itself as part of the interplay between man and nature. The scientific method ... changes and transforms its object: the procedure can no longer keep its distance from the object.

Nonsense. Space is blue and birds fly through it.

...separation of the observer from the phenomenon to be observed is no longer possible.
