"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.

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 would not be beholden to a tyrant, for his acts of tyranny. For it is but usurpation in him to save, as their rightful lord, the lives of men over whom he has no title to reign.
Woes and wonders of power, that tonic hell, synthesis of poison and panacea.
If truth is the main casualty in war, ambiguity is another.
Well, I think the worst part about tribalism is its tendency to fundamentalize, and if I can fight fundamentalism in any of its forms I'm happy.
The carnal person fears man, not God. The strong Christian fears God, not man. The weak Christian fears man too much, and God too little.
Every walker is a guard on patrol to protect the ineffable.
