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 believe in men waiting until they are ready to die before using any of their money for helpful purposes.
You wake up white, and you think about certain things every day. You wake up black, and you think about certain things. You wake up Chinese, and you think certain things - but those things aren't major. What's major is that you are good at your craft.
From birth to death you go on living, groping in darkness with no light - and you could have created the light. You cannot find it in the scriptures; nobody can hand it to you. It is not purchased or sold; it is nontransferable. But you can create it - you can put all your energies together. You can start living consciously from this very moment.
Sob, heavy world Sob as you spin, Mantled in mist Remote from the happy.
Over time, the ghosts of things that happened start to turn distant; once they've cut you a couple of million times, their edges blunt on your scar tissue, they wear thin. The ones that slice like razors forever are the ghosts of things that never got the chance to happen.
Bras are a ludicrous invention; but if you make bralessness a rule, you're just subjecting yourself to yet another repression.
