The Bohr quote:
"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."
Can be found in the following:
A. Petersen "The philosophy of Niels Bohr" The Bulletin of the Atomic
Scientists, September 1963, p. 8
(http://tonno.tesre.bo.cnr.it/~foschini/wisdom.html)
Heinz R. Pagels,The Cosmic Code, p. 85
Euan Squires, The Mystery of the Quantum World, Bristol: Institute of
Physics Publishing, 1994, p. 117-8.
However, I don't know where the original quote came from. The original
context it seems was a defence of the Copenhagen Interpretation and
anti-realism.
