"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 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.
When you get to know a lot of people, you make a great discovery. You find that no one group has a monopoly on looks, brains, goodness or anything else. It takes all the people - black and white, Catholic, Jewish and Protestant, recent immigrants and Mayflower descendants - to make up America.
Nothing that comes from the deep, passional soul is bad, or can be bad.
The Church is called to draw near to every person, beginning with the poorest and those who suffer.
The only thing worse than a bad review from the Ayatollah Khomeini would be a good review from the Ayatollah Khomeini.
So what exactly are the rewards of resentment. It is always a relief to know that the reason we have failed in life is not because we lack the talent, energy, or determination to succeed, but because of a factor that is beyond our control and that has loaded the dice decisively against us.
Now, one of the most essential branches of English liberty is the freedom of one's house.
