This document discusses a talk given by William W Nazaroff on collaborating to study indoor microbiomes from Newtonian and Darwinian perspectives. It summarizes Harte's analysis of how physicists and ecologists approach their work differently, with physics seeking simplicity and universality while ecology finds increasing complexity. Nazaroff observes successful collaborations occur in small groups that foster mutual trust, teaching, and credit-sharing. Studying indoor microbiomes provides opportunities to advance understanding, though sustained support and challenging assumptions will be needed to overcome inertia. Nazaroff's own collaboration with Peccia's lab is producing results on indoor bacteria and fungi emissions.
