Paperback. Condition: New. Print on Demand. This book explores the history and state of knowledge of pollen, revealing its integral role in plant fertilization. The author delves into the microscopic world of pollen, detailing its structure, composition, and function. Through meticulous observations, he sheds light on the complex interplay between pollen and the female reproductive organs of plants, illuminating the intricacies of plant life. The book's detailed descriptions of pollen types, their unique adaptations, and the mechanisms involved in pollination broaden our understanding of plant diversity and evolution. It highlights the significance of pollen analysis as a tool for understanding past vegetation patterns and climatic conditions. By tracing the history of pollen research, the author demonstrates how scientific advancements have shaped our understanding of this remarkable substance. Providing a comprehensive and accessible account, this volume deepens our appreciation for the fundamental role pollen plays in the flourishing of plant life and ecosystem dynamics.

Hardcover. Condition: Very Good. BROWN, Robert. "Mikroskopische Beobachtungen über die im Pollen der Pflanzen enthaltenen Partikeln, und über das allgemeine Vorkommen activer Molecüle in organischen und unorganischen Körpern.(Unter dem Titel: A Brief Account of Microscopical Observations made in the months of June, July and August, 1827, on the particles contained in the pollen of plants; and on the general existence of active molecules in organic and inorganic bodies.") In: Annalen der Physik und Chemie. Leipzig, Johann Barth, 1828, series II, vol 14, pp. 294-313 in the full volume of viii, 628 (ii) pp with 5 engraved plates. First German edition of Brown's seminal paper the discovery of "Brownian Motion".  This is the first physical demonstration of atomism and the first time it appeared in German from the original English earlier that year. "Brownian motion (named after the botanist Robert Brown) or pedesis (from Greek the Greek for "leaping") is the presumably random drifting of particles suspended in a fluid (a liquid or a gas) or the mathematical model used to describe such random movements, which is often called a particle theory. The mathematical model of Brownian motion has several real-world applications. An often quoted example is stock market fluctuations, however, movements in share prices may arise due to unforeseen events which do not repeat themselves. Brownian motion is among the simplest of the continuous-time stochastic (or probabilistic) processes, and it is a limit of both simpler and more complicated stochastic processes (see random walk and Donsker's theorem). This universality is closely related to the universality of the normal distribution. In both cases, it is often mathematical convenience rather than the accuracy of the models that motivates their use. This is because Brownian motion, whose time derivative is everywhere infinite, is an idealised approximation to actual random physical processes, which always have a finite time scale."--Wikipedia "In the course of these microscopical explorations Brown passed from the study of the ovule to that of pollen grains, and thus came to investigate the phenomenon known as the Brownian movement, i.e., the continuous motion of minute particles suspended in a fluid, which results from their being bombarded by molecules in like continuous motion. He took care to point out that the motion of the particles within had earlier been obscurely seen by Needham, and distinctly by Gleichen, but to Brown belongs the credit for establishing such motion as a property not simply of living pollen but of all minute particles, inorganic as well as organic, suspended in a fluid. Here again it remained for others to carry Brown s work much further and to demonstrate its relevance to the kinetic theory of gases.". See: Magie, "A Source Book in Physics" pp. 251-255; Sparrow, "Milestones of Science" # 31. [++] [Note: the first printing of the Brown paper occurs in The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science 4, September 1828, and is the paper in which Brown first described his observation of Brownian motion.] [++] Also in this volume are contributions by Gustavus Magnus, C.G. Gmelin, Th. Sassure, J. Liebig, Berzelius, de la rive, Candolle, and others.…

Hardcover. Condition: Very Good. Leipzig, Johann Ambrosius Barth, 1828. Published in Annalen der Physik und Chemie in Band 14, Zweites Stück, 1828, appearing on pp 294-324. We offer the entire volume, pp viii, 628pp, six folding plates. The volume is bound in half-cloth and marbled boards. This copy is in VERY GOOD condition, and is from the library of Wright-Patterson Field, Dayton Ohio, and earlier from the library of the Deutsche Akademie der Luftfahrtforschung (Berlin, founded 1938/9 and active until 1944). There is another, older, contemporary library stamp on the title page, small (about 1 inch) oval, mostly faded away, though I can identify that the library was in Aachen. Condition notes: this is a nice copy, with "Wright Field Library/Dayton, Ohio" rubber stamped on the page edges at top and bottom of textblock.
