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.'
If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.
Interpretation
What this quote means
