Many physicists like to drink coffee. Some of them like to write about coffee. Some of them like to write about things they notice while they look at a coffee cup. Here’s a new example of one or more of those things:

“Science of a coffee cup: a physicist walks into a bar…,” Aleksi Bossart, Romain Fleury, Benjamin Apffel, arXiv:2501.01180, 2024. The abstract of the study says:

“… and annoys everyone with unsolicited experiments. The present paper proposes a short pedagogical review of the various phenomena that can be observed in a coffee cup with little to no equipment. The physical domains spanned include acoustics, optics and, of course, fluid mechanics. The variety of experimental and theoretical techniques introduced throughout the paper makes it suitable for a broad audience. For each topic, we first propose an experimental realization before introducing a minimal model to explain the observations. We end each section by discussing more advanced works existing in the literature as well as related applications. We provide detailed experimental procedures and videos of the experiments that can be freely used for teaching purposes. The phenomena presented here also show remarkable efficiency as icebreakers for morning coffee in laboratories or conferences.”
