And anyone who thinks they can talk about quantum theory without feeling dizzy hasn't yet understood the first thing about it.
Interpretation
Understanding quantum theory requires deep comprehension, and it can be overwhelming for many.
Niels Bohr's quote highlights the complexity and often bewildering nature of quantum theory. It suggests that truly grasping the intricacies of the subject can lead to a feeling of dizziness, indicating both the intellectual challenge it presents and the profound nature of the phenomena it describes.
In practice
In a lecture on advanced physics, one might use this quote to illustrate the challenges of comprehending quantum mechanics.
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.
Everything we call real is made of things that cannot be regarded as real.
When I left NASA, I was looking at how you could use space technologies for developing countries' work.
The challenge of global warming should stimulate a whole raft of manifestly benign innovations - for conserving energy and generating it by 'clean' means (biofuels, innovative renewables, carbon sequestration, and nuclear fusion).
More than any other product of human scientific culture scientific knowledge is the collective property of all mankind.
There is a single light of science, and to brighten it anywhere is to brighten it everywhere.
Gravitational waves, because they are so imperturbable - they go through everything - they will tell you the most information you can get about the earliest instants that go on in the universe.
Humans are natural-born scientists. When we're born, we want to know why the stars shine. We want to know why the sun rises.
