"Uncertainty" is NOT "I don't know." It is "I can't know." "I am uncertain" does not mean "I could be certain."
Interpretation
Uncertainty implies a limitation in knowledge rather than just a lack of knowledge.
Heisenberg's quote emphasizes the profound nature of uncertainty in knowledge and existence. Unlike mere ignorance, which denotes a possibility of knowing, uncertainty signifies an inherent limitation in our ability to understand or predict certain aspects of reality, highlighting that some things are fundamentally beyond our grasp.
In practice
In a classroom discussion about the nature of knowledge.
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.
Jesus Christ belonged to the true race of prophets. He saw with open eye the mystery of the soul. Drawn by its severe harmony, ravished with its beauty, he lived in it and had his being there. Alone in all history, he estimated the greatness of man.
Being solo really lends itself to different interpretations - and everything is in the moment and on a whim. I never realised how far out you can go when you are by yourself.
I said that if an alien came to visit, I'd be embarrassed to tell them that we fight wars to pull fossil fuels out of the ground to run our transportation. They'd be like, 'What?'
The first right on earth is the right of the ego. Man's first duty is to himself. His moral law is never to place his prime goal within the persons of others. His moral obligation is to do what he wishes, provided his wish does not depend primarily upon other men.
I wanted to be a psychological engineer, but we lacked the facilities, so I did the next best thing - I went into politics. It's practically the same thing.
Wake up, you idiots! Whatever made you think that money was so valuable?
