Anyone who can contemplate quantum mechanics without getting dizzy hasn't understood it.
Interpretation
Understanding quantum mechanics challenges our conventional thinking and can be overwhelming.
The quote by Niels Bohr humorously suggests that quantum mechanics is inherently complex and perplexing. It implies that if one can fully grasp its intricacies without feeling disoriented, they may have missed the true essence of its bewildering nature. This highlights the difficulty of comprehending concepts that defy everyday experiences and logical reasoning.
In practice
This quote can be used in a lecture to emphasize the challenges of teaching quantum physics.
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.
Imagine the progress that could be made by gathering together the world's scientists, engineers, physicians, oncologists, epidemiologists and more in a super-team effort to end cancer.
It is seen that both matter and radiation possess a remarkable duality of character, as they sometimes exhibit the properties of waves, at other times those of particles. Now, it is obvious that a thing cannot be a form of wave motion and composed of particles at the same time - the two concepts are too different.
I like to think that Einstein would look at string theory’s journey and smile, enjoying the theory’s remarkable geometrical features while feeling kinship with fellow travelers on the long and winding road toward unification.
I suggest that going to Mars means permanence on the planet - a mission by which we are building up a confidence level to become a two-planet species.
I call on all scientists in all countries to cease and desist from work creating, developing, improving and manufacturing further nuclear weapons - and, for that matter, other weapons of potential mass destruction such as chemical and biological weapons.
Mathematics as a science, commenced when first someone, probably a Greek, proved propositions about "any" things or about "some" things, without specifications of definite particular things.
