Thus, the more precisely the position is determined, the less precisely the momentum is known, and conversely.

We will have to abandon the philosophy of Democritus and the concept of elementary particles. We should accept instead the concept of elementary symmetries.
Werner Heisenberg
Image
Not only is the Universe stranger than we think, it is stranger than we can think.
Werner Heisenberg

The solution of the difficulty is that the two mental pictures which experiment lead us to form - the one of the particles, the other of the waves - are both incomplete and have only the validity of analogies which are accurate only in limiting cases.
Werner Heisenberg

My mind was formed by studying philosophy, Plato and that sort of thing.
Werner Heisenberg
Image
What we observe is not nature itself, but nature exposed to our method of questioning.
Werner Heisenberg

Every tool carries with it the spirit by which it has been created.
Werner Heisenberg

The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.
Werner Heisenberg

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

I believe that the existence of the classical path can be pregnantly formulated as follows: The path comes into existence only when we observe it.

The violent reaction on the recent development of modern physics can only be understood when one realises that here the foundations of physics have started moving and that this motion has caused the feeling that the ground would be cut from science
Werner Heisenberg
Image
A consistent pursuit of classical physics forces a transformation in the very heart of that physics.

It is probably true quite generally that in the history of human thinking the most fruitful developments frequently take place at those points where two different lines of thought meet.
Werner Heisenberg

It was about three o'clock at night when the final result of the calculation [which gave birth to quantum mechanics] lay before me ... At first I was deeply shaken ... I was so excited that I could not think of sleep. So I left the house ... and awaited the sunrise on top of a rock.

In the strict formulation of the law of causality—if we know the present, we can calculate the future—it is not the conclusion that is wrong but the premise. On an implication of the uncertainty principle.

Science clears the fields on which technology can build.
Werner Heisenberg

Nature allows only experimental situations to occur which can be described within the framework of the formalism of quantum mechanics
Werner Heisenberg
Image
Every word or concept, clear as it may seem to be, has only a limited range of applicability.
Werner Heisenberg
Image
It seems sensible to discard all hope of observing hitherto unobservable quantities, such as the position and period of the electron... Instead it seems more reasonable to try to establish a theoretical quantum mechanics, analogous to classical mechanics, but in which only relations between observable quantities occur.

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.
