What we observe is not nature itself, but nature exposed to our method of questioning.
Interpretation
This quote emphasizes that our understanding of nature is shaped by the questions we ask and how we investigate it.
Heisenberg suggests that our perceptions of the natural world are not direct reflections of reality but are instead influenced by our inquiries and the frameworks we use to interpret observations. The statement implies that knowledge is not just about passive observation; rather, it is an active process that depends heavily on human curiosity and the methodologies employed in scientific exploration.
In practice
In a lecture on scientific methodology, one could use this quote to illustrate the importance of asking the right questions in research.
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.
I don't have any authority to talk about the domestic policies of America. But as an outsider, I am mystified by the fact that you are encouraged to buy a gun, but if you use it for the purpose that it is expressly designed for, you get the death penalty. That aspect of America is kind of mystifying.
When the province of physical theory was extended to encompass microscopic phenomena through the creation of quantum mechanics, the concept of consciousness came to the fore again. It was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.
Some people who've read my story think I had a terrible childhood and that I was neglected or even abused, while others feel that my parents, while certainly flawed, also had truly wonderful qualities. And that's the way it should be, because in real life two people can look at the same president and one will see a hero and the other a villain.
What keeps us from abandoning ourselves entirely to one vice, often, is the fact that we have several.
People need to be fed, medicated, educated, clothed, and sheltered, and if we're compassionate we'll help them, but you get no moral credit for forcing other people to do what you think is right. There is great joy in helping people, but no joy in doing it at gunpoint.
The tourist was the great conservative who hated novelty and adored dirt.
