Here I derive a Boltzmann distribution in a simple pedagogical example using only tools from a first-year probability course. The example is called \"coconuts and islanders\" and was taught to me by my father, Shoucheng Zhang (1963 - 2018), to whom these notes are dedicated. By focusing on this simple story, which can be easily simulated on a computer, I aim to provide a more accessible and intuitive presentation of the Boltzmann distribution. Yet I hope this exposition also inspires deep thinking about statistical physics. For instance, I show that the coconuts and islanders story illuminates a connection between the \"fundamental assumption of statistical mechanics\"---all microstates are equally probable---and the statistical property of detailed balance.", "revisions": [ { "version": "v1", "updated": "2019-04-07T22:39:00.000Z" } ], "analyses": { "keywords": [ "boltzmann distribution", "statistics-first guide", "islanders story illuminates", "first-year probability course", "thermal physics" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
