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. — 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)
