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.
New, distant Scenes of endless Science rise: So pleas'd at first, the towring Alps we try.
Polls consistently show that the majority of Americans favour research using embryonic stem cells and yet politicians continue to pander to the outspoken religious minority that is hampering efforts to develop this potentially valuable technology.
Evolution, thus, is merely contingent on certain processes articulated by Darwin: variation and selection. No longer is a fixed object transformed, as in transformational evolution, but an entirely new start is, so to speak, made in every generation.
If you come from mathematics, as I do, you realize that there are many problems, even classical problems, which cannot be solved by computation alone.
At lunch Francis [Crick] winged into the Eagle to tell everyone within hearing distance that we had found the secret of life.
If you represent the Earth's lifetime by a single year, say from January when it was made to December, the 21st-century would be a quarter of a second in June - a tiny fraction of the year. But even in this concertinaed cosmic perspective, our century is very, very special: the first when humans can change themselves and their home planet.
