I think we can find a way to describe ourselves (all matter modelers) in a concise, unified manner.
We want to be inclusive of those who study atomic and molecular physics, theoretical and computational chemistry, condensed matter and materials physics, biophysics as well as comp molecular bio, and computer science, informatics, data-science, and mathematics applied to any of the mentioned fields. As MMSE matures, it is becoming a community of all who engage in mathematical and computational modeling of matter, from the subatomic to the thermodynamic limit.
So, I propose:
Q&A for the scientific communities of the theoretical and computational physical and natural sciences, that focuses on unravelling the properties of matter from the subatomic to the macroscopic scales using quantitative methods.
