But I&#x27;d say it&#x27;s unusual to find someone who is both a researcher and a popularizer.<p>&gt; Also, isn&#x27;t quantum chemistry too applied for there to be significant arguments about specific interpretations?<p>I suppose that is mainly the point of my original post; the vast majority of researchers who utilize QM do so without regard to the philosophical aspects of the subject.  Wouldn&#x27;t you think Sean Carroll is an outlier in that sense?
