The Online Distributed Proofreading Team at https://www.pgdp.net "Von Sonnen und Sonnenstäubchen : Kosmische Wanderungen" by Wilhelm Bölsche is a collection of popular-science essays written in the early 20th century. The volume ranges across astronomy, geology, evolution, and animal life, blending travel vignette, philosophy, and clear exposition to make modern science vivid to general readers. Its unifying theme is a human-scaled tour through cosmic and natural history, from suns to “sun-dust,” showing how scientific facts cohere into a larger, poetic vision of the world. The opening of the volume begins with a preface that calls Earth and humanity “sun-dust” and states the aim of throwing clarifying light onto the heaped “dust” of modern facts so they shine as a unified whole. It then follows a night hike in the Riesengebirge, where a tear in the fog reveals the Milky Way and sparks a sweeping meditation from ancient myth and medieval spheres to the Age of Discovery, Copernican astronomy, Newtonian law, energy conservation, geological deep time, and evolutionary ascent. Using striking analogies—the Berlin city map to scale the solar system, and a coin’s edge to explain why the Milky Way appears as a bright band—the narrative reviews ideas from Democritus, Dante, Copernicus, Galileo, Bruno, Newton, Robert Mayer, Kant, Herschel, Humboldt, Kirchhoff, Bunsen, Draper, and Scheiner. It separates gaseous nebulae within our stellar system from true “island universes” and, via spectroscopy (Fraunhofer lines) and photography, argues that the Andromeda nebula is a distant star system beyond our own, before turning to the pitfalls of perception and the newly fixed shapes of nebulae, leading toward the famous Ring Nebula.
