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.
Nothing in biology makes sense except in the light of evolution.
Land on Mars, a round-trip ticket - half a million dollars. It can be done.
Science must have originated in the feeling that something was wrong.
The atomic bomb certainly is the most powerful of all weapons, but it is conclusively powerful and effective only in the hands of the nation which controls the sky.
It is an error to imagine that evolution signifies a constant tendency to increased perfection. That process undoubtedly involves a constant remodeling of the organism in adaptation to new conditions; but it depends on the nature of those conditions whether the direction of the modifications effected shall be upward or downward.
When you're in a spacecraft, you need to know what things you can touch and what things you shouldn't touch!
