TY, AG > What then is physics if it is not the search for the Law of Nature, the quest for the absolute Truth, nor the Keplerian attempt to read the mind of God? Since the formation of the Royal Society, one could describe physics as the systematic discovery of what processes we can carry out and how we can predict their outcomes. As long as the universe continues to surprise us with new opportunities and dangers, physics in this sense will be an important element of our strategy to survive and prosper in it. Since there can be no final quantum experiment, there is little reason to fear that there will be a final quantum theory. -David Filkenstein in The state of quantum physics The underlying error may be the conviction that the system itself has to be represented in order to represent our actions upon it. In quantum theory we represent actual operations and the relations among them, not a hypothetical reality on which they act. Quantum theory is a theory of actuality, not reality. I have taken this term from Whitehead’s writings. –David Finkelstein in The state of quantum physics
