Nature allows only experimental situations to occur which can be described within the framework of the formalism of quantum mechanics
Interpretation
This quote emphasizes that nature operates within the rules of quantum mechanics and that our understanding is limited to experimental observations.
Werner Heisenberg's quote reflects the idea that the natural world behaves according to the principles of quantum mechanics, allowing us to understand and describe phenomena only through empirical experiments. It highlights the limitations of classical physics in capturing the intricacies of nature at a quantum level, suggesting that our knowledge is constrained to what can be measured and observed experimentally.
In practice
In a discussion about the implications of quantum mechanics on modern physics.
Although the theory of relativity makes the greatest of demands on the ability for abstract thought, still it fulfills the traditional requirements of science insofar as it permits a division of the world into subject and object (observer and observed) and, hence, a clear formulation of the law of causality.
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.
It is generally believed that our science is empirical and that we draw our concepts and our mathematical constructs from the empirical data. If this were the whole truth, we should, when entering into a new field, introduce only such quantities as can directly be observed, and formulate natural laws only by means of these quantities.
When I meet God, I am going to ask him two questions: Why relativity ? And why turbulence ? I really believe he will have an answer for the first.
The end of the First World War had thrown Germany's youth into great turmoil. The reins of power had fallen from the hands of a deeply disillusioned older generation, and the younger ones drew together in larger and smaller groups to blaze new paths or, at least, to discover a new star to steer by.
The Same organizing forces that have shaped nature in all her forms are also responsible for the structure of our minds.
It would be wrong to assume that one must stay with a research programme until it has exhausted all its heuristic power, that one must not introduce a rival programme before everybody agrees that the point of degeneration has probably been reached.
No doubt science cannot admit of compromises, and can only bring out the complete truth. Hence there must be controversy, and the strife may be, and sometimes must be, sharp. But must it even then be personal? Does it help science to attack the man as well as the statement? On the contrary, has not science the noble privilege of carrying on its controversies without personal quarrels?
Understanding vision and building visual systems is really understanding intelligence.
Evolution is as much a fact as the heat of the sun.
Physicists analyse systems. Web scientists, however, can create the systems.
The Big Bang banged, and for some reason we’re here. And that’s astonishing. And that we can understand that, that’s the most astonishing.
