1075:. The papers indeed "assume" molecules. Based on this assumption, the physical model of Brownian motion makes certain predictions which match critical experimental evidence which otherwise is not explained. Retrospectively, historians trace the acceptance of molecules to the realization that these papers provide a good model, and hence molecules became broadly accepted. That is how physics proceeds. Primary sources should not be the basis of claims in Knowledge.

Einsteins 1905 paper and Smoluchowskis 1906 paper present Brownian motion as proof that molecules exist. I have now, for another reason read those papers, and at no point is the existence of molecules questioned, or considered necessary to be
