After hearing John Ralston's talk at the Nov. 8-10, 2012 APS meeting, "Quantum mechanics without Planck's constant" I read his paper of the same name, arXiv:1203.5557. After hearing the talk my first question was, Is this correct? My second question was, Is this just a change of variables, a kind of principal component analysis? (dimensional analysis?)
Even if no new physics comes from Ralston's reworking of quantum theory there might be important changes to our ontology (see my Feb. 26, 2012 blog).
