the term "Marseille" is used humorously in part, it could also be called the "Haifa Interpretation" because Asher Peres contributed and he was at the Technion and also David Mermin at Cornell (Ithaca, NY) has written similar stories about how to interpret QM and has called his stories the "Ithaca Interpretation" Or it could be called "Princeton" because of B. van Fraasen's contribution, or one could cite Michel Bitbol who is somewhere in France and call it the "French" interpretation. That actually sounds OK and would include the Marseille people. ================== Anyway we need a thread that focuses just on the Marseille interpretation of QM and does not get sidetracked. I need some peace and absence of distraction in order to unfold whatever it is this has to tell us. ================== The first thing to say is that INTERPRETATION has to do with the STORIES rather than the mathematical notation or "formalism". Two people can use the same or very similar formulations----the same subscripts and the same equations, or almost the same---and interpret them in radically different ways. when we are discussing interpretation, similarity at the level of symbolic notation is SUPERFICIAL RESEMBLANCE and what is deep is the stories. =================== An illustration of this is that the math of Special Rel was developed by a highly respectable Dutchman named Hendrik Lorentz, who unfortunately told the wrong STORIES about it. One could say Einstein's contribution to Special Rel was an INTERPRETATION of formulas that were already there. He found the right philosophical spin to put on them. In particular he found that you had to give up the intuitive notion of SIMULTANEITY. ============= Simultaneity was deeply rooted in the human mind, for a reason I will discuss, and in order to tell the right stories about the Lorentz transformations you had to give it up-----eradicate, meaning tear out by the roots. Not easy to do. A purely philosophical step, and nevertheless necessary to the development of physics at that junction. ============= So we have to be alert to whatever the Marseille Interpretation is asking us to give up. It will be something that seems obvious to us but for which there is no actual concrete evidence.
