Alan J. Rocke - Böcker

Chemists in the nineteenth century were faced with a particular problem: how to depict the atoms and molecules beyond the direct reach of our bodily senses. In visualizing this microworld, these scientists were the first to move beyond high-level philosophical speculations regarding the unseen. In "Image and Reality", Alan J. Rocke focuses on the community of organic chemists in Germany to provide the basis for a fuller understanding of the nature of scientific creativity. Arguing that visual mental images assisted many of these scientists in thinking through old problems and new possibilities, Rocke uses a variety of sources, including private correspondence, diagrams and illustrations, scientific papers, and public statements to investigate their ability to not only imagine the invisibly tiny atoms and molecules upon which they operated daily, but to build detailed and empirically based pictures of them. These portrayals of 'chemical structures' gradually became an accepted part of science and are now regarded as one of the defining features of chemistry.In telling this fascinating story, Rocke also suggests that imagistic thinking is often at the heart of creative thinking in all fields.

This book provides an English translation of the early fundamental contributions of Lothar Meyer (1830-1895) regarding his independent discovery, coincident with that of Dmitrii Mendeleev, of the periodic system of the elements. Although an English translation of the 5th edition of Meyer´s book Modern Theories of Chemistry and their Significance for Chemical Statics was published in 1888, this will be the first time that these crucial early texts will be available in English. These writings reveal details regarding Meyer´s research pathway to the idea of periodicity and to an arrangement of the chemical elements in tables and graphs.An introductory commentary and interpolated editorial footnotes to the texts clarify the (physico)-chemical background regarding the various shifts in thought during the crucial period from 1860 to the early 1870s. A short biography of Lothar Meyer completes the book.The volume includes a complete translation of the first edition of Modern Theories of Chemistry and their Significance for Chemical Statics (1864), the ground-breaking paper “The Nature of the Chemical Elements as a Function of their Atomic Weights” in Annalen der Chemie und Pharmacie, suppl. vol. 7 (1870), 354-64, and portions of the revised second edition of Modern Theories of Chemistry and their Significance for Chemical Statics (1872).

Hermann Kopp (1817–1892) is best remembered today as a historian of chemistry, but during his lifetime he was one of the most eminent chemists of his day, and one of the earliest pioneers of physical chemistry.
