Bohr-Einstein debate

Surprisingly, the debate between an 'absolute truth' and a world without an absolute was debated between Einstein and Bohr too, known as the Bohr-Einstein debate.

Bohr: (summarized by Aage Peterson, his assistant)

"There is no quantum world. There is only an abstract quantum physcial 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."

It isn't very clear to me, just from this summary alone, but perhaps if you've read the pre text, it's saying that "Observations not only disturb what has to be measured, they produce it", by choosing your frame of refernce, for instance how to measure or from which perspective you are measuring or observing, it will determine what kind of results you get. Before measuring, everything just exists in a state of possibilities and probabilities.
