Von Sonnen und Sonnenstäubchen : $b Kosmische Wanderungen
"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.

Het paard : $b in zijne natuurlijke ontwikkeling
"Het paard : in zijne natuurlijke ontwikkeling" by Wilhelm Bölsche is a popular scientific treatise written in the early 20th century. It explores the natural history and evolution of the horse, tracing its lineage from small, multi‑toed ancestors to the modern, single‑toed runner, and examines its close symbiosis with humans as a domesticated animal. Expect a blend of anatomy, paleontology, and behavioral insight that connects fossil evidence, comparative anatomy, and cultural history to explain what makes the horse unique. The opening of this work sets out its purpose: to tell the full evolutionary story of the horse, beginning with tiny Eocene ancestors and linking them to living forms and domestic breeds. It recaps the rise of mammals from reptile‑like forebears through monotremes and marsupials to early placental groups, highlighting a pivotal Eocene fauna (the “Cernays” forms) from which hoofed animals emerge. The text defines domestication as a lasting symbiosis rather than mere captivity, illustrating the idea with classic plant–fungus and ant–aphid partnerships before applying it to horses, dogs, and livestock. A clear, step‑by‑step anatomical comparison explains how the horse stands on a single middle toe, with splint bones as vestiges of lost digits, and how this design achieves speed, endurance, and load‑bearing. It then sketches the horse’s instincts and signal‑sensitivity (including the “Clever Hans” case) and turns to the fossil record, from Cuvier’s early finds to the rich American deposits, noting that true horses once ranged widely in the Americas before disappearing there prior to European contact.
