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… — Werner Heisenberg Copy Share Image
The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory… — Werner Heisenberg Copy Share Image
“Revere those things beyond science which really matter and about which it is so difficult to speak.” — Werner Heisenberg Copy Share Image
“In the history of science, ever since the famous trial of Galileo, it has repeatedly been claimed that scientific truth cannot be reconciled with… — Werner Heisenberg Copy Share Image
The more closely you look at one thing, the less closely can you see something else. — Werner Heisenberg Copy Share Image
I think that if a United States of Europe were to be formed, it would be in our interests to fight for it, as… — Werner Heisenberg Copy Share Image
Whether we electrons, light quanta, benzol molecules, or stones, we shall always come up against these two characteristics, the corpuscular and the undular. — Werner Heisenberg Copy Share Image
It is probably true quite generally that in the history of human thinking the most fruitful developments frequently take place at those points where… — Werner Heisenberg Copy Share Image
If we made atomic bombs, we would bring about a terrible change in the world. Who knows what would happen from this? — Werner Heisenberg Copy Share Image
The positivists have a simple solution: the world must be divided into that which we can say clearly and the rest, which we had… — Werner Heisenberg Copy Share Image
“what we observe is not nature itself, but nature exposed to our method of questioning’.77” — Werner Heisenberg Copy Share Image
A consistent pursuit of classical physics forces a transformation in the very heart of that physics. — Werner Heisenberg Copy Share Image
It was about three o'clock at night when the final result of the calculation [which gave birth to quantum mechanics] lay before me ...… — Werner Heisenberg Copy Share Image
Only a few know, how much one must know to know how little one knows. — Werner Heisenberg Copy Share Image
![“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.” quote by Werner Heisenberg](https://sms4smile.com/quotes/img-quotes/bba/werner-heisenberg-4501_birth_it-was-about-three-o-clock-at-night-when_265746.jpg)
