While the finish given to our picture of the world by the theory of relativity has already been absorbed into the general scientific consciousness, this has scarcely occurred to the same extent with those aspects of the general problem of knowledge which have been elucidated by the quantum theory.
Interpretation
Niels Bohr suggests that while relativity is widely accepted in understanding the universe, quantum theory's implications for knowledge remain less understood.
In this quote, Niels Bohr reflects on the contrasting acceptance of two foundational theories in physics: relativity and quantum theory. He points out that although the implications of relativity have become well-integrated into scientific understanding and common consciousness, the deeper philosophical and conceptual challenges posed by quantum theory have not yet been fully realized or appreciated by society at large, emphasizing a gap in understanding the nature of knowledge itself.
In practice
In a lecture about the implications of quantum mechanics on modern science.
When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'
An independant reality in the ordinary physical sense can neither be ascribed to the phenomenon nor to the agencies of observation.
An expert is a man who has made all the mistakes which can be made, in a narrow field.
Those who are not shocked when they first come across quantum theory cannot possibly have understood it.
When searching for harmony in life one must never forget that in the drama of existence we are ourselves both actors and spectators.
And anyone who thinks they can talk about quantum theory without feeling dizzy hasn't yet understood the first thing about it.
Once you can reproduce a phenomenon, you are well on the way to understanding it.
It now appears that the way the universe began can indeed be determined, using imaginary time.
Scientific and technological progress themselves are value-neutral. They are just very good at doing what they do. If you want to do selfish, greedy, intolerant and violent things, scientific technology will provide you with by far the most efficient way of doing so. But if you want to do good, to solve the world's problems, to progress in the best value-laden sense, once again, there is no better means to those ends than the scientific way.
The enemy of science is not religion... . The true enemy is the substitution of thought, reflection, and curiosity with dogma.
Every great advance in natural knowledge has involved the absolute rejection of authority.
The idea of atomic energy is illusionary but it has taken so powerful a hold on the minds, that although I have preached against it for twenty-five years, there are still some who believe it to be realizable.
