A final moral concerns terminology. Why did such serious people take so seriously axioms which now seem so arbitrary? I suspect that they were misled by the pernicious misuse of the word ‘measurement’ in contemporary theory. This word very strongly suggests the ascertaining of some preexisting property of some thing, any instrument involved playing a purely passive role. Quantum experiments are just not like that, as we learned especially from Bohr. The results have to be regarded as the joint product of ‘system’ and ‘apparatus,’ the complete experimental set-up.

It seems clear that the present quantum mechanics is not in its final form. Some further changes will be needed, just about as drastic as the changes made in passing from Bohr's orbit theory to quantum mechanics. Some day a new quantum mechanics, a relativistic one, will be discovered, in which we will not have these infinities occurring at all. It might very well be that the new quantum mechanics will have determinism in the way that Einstein wanted.
Paul Dirac
Present an explanation of Gomatam's interpretation of Bohr's interpretation of quantum mechanics. You do not need to include your own interpretation of Bohr or evaluate whether Gomatam is getting Bohr's view correct. But you should articulate the conception of reality offered Gomatam's Bohr. In doing so, you should make clear whether Gomatam's Bohr solves the measurement problem and to what extent his account makes sense. Your paper should be approximately 1000-2500 words.

It seems to me that we must make a distinction between what is "objective" and what is "measurable" in discussing the question of physical reality, according to quantum mechanics. The state-vector of a system is, indeed, not measurable, in the sense that one cannot ascertain, by experiments performed on the system, precisely (up to proportionality) what the state is; but the state-vector does seem to be (again up to proportionality) a completely objective property of the system, being completely characterized by the results it must give to experiments that one might perform.
Roger Penrose
Let's begin with capitalism, a word that has gone largely out of fashion. The approved reference now is to the market system. This shift minimizes — indeed, deletes — the role of wealth in the economic and social system. And it sheds the adverse connotation going back to Marx. Instead of the owners of capital or their attendants in control, we have the admirably impersonal role of market forces. It would be hard to think of a change in terminology more in the interest of those to whom money accords power. They have now a functional anonymity.
John Kenneth Galbraith
Two features of QT are commonly taken to be fundamentally non-classical: the absolute randomness of single events in the atomic regime, and the need for a permanent record of the experiment obtained using a macroscopic experimental arrangement…QT can also be applied to the larger system consisting of the original atomic system plus the macroscopic experimental arrangement. In this case, however, the larger system needs to interact with another stage of macroscopic recording. Since this procedure can continue ad infinitum, and is decisively terminated only when the result of an experiment is interpreted by a conscious observer, some noted quantum theorists have promoted the view that the quantum theory has some nexus with the consciousness of the observer...
