If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.
Interpretation
Understanding quantum physics is so complex that it can overwhelm those who truly grasp its principles.
Niels Bohr emphasizes that the profound and often counterintuitive nature of quantum physics is such that a true understanding leads to a sense of wonder or even confusion. If one feels unfazed by the complexities of quantum mechanics, it likely indicates that they have not fully grasped its intricacies and the philosophical implications it carries.
In practice
During a lecture on advanced physics, a professor might quote Bohr to illustrate the challenging nature of 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.
And anyone who thinks they can talk about quantum theory without feeling dizzy hasn't yet understood the first thing about it.
It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.
Any difficulties which the world faces today will be as nothing compared to the full effects which global warming will have on the world-wide economy.
Quantum physics thus reveals a basic oneness of the universe.
I would only once have the opportunity to let my scientific career encompass a path from the double helix to the three billion steps of the human genome.
The first colony on Mars is not going to be built by a private company. How are you going to make money? You're not.
I have the idea that running shoes are based on a kind of cult idea - that our feet are flawed and we need shoes to correct those flaws. The shoe companies are in the business of selling shoes. But there's no evidence from running shoe manufacturers that they're right. There's no scientific data that running shoes reduce injury.
