Book Description
This is not a history of chemistry which uses stamps instead of the usual illustrations, but a collection of short essays and comments on such chemistry as can be found on postage stamps and other philatelic items. In other words, the choice of topics is dictated by the philatelic material available, with the necessary consequence that important parts of chemical history will be missing for the simple reason that they have not found their way onto postage stamps. Thus, the reader may find detailed comments on lesser known chemists, such as Wilhelm August Lampadius who has been honoured with two stamps by the German Post Office, but hardly anything on such luminaries as Robert Bunsen, who have not been deemed worthy of a commemorative issue.

Book Description
This book provides an overview of the origins and evolution of the periodic system from its prehistory to the latest synthetic elements and possible future additions. The periodic system of the elements first emerged as a comprehensive classificatory and predictive tool for chemistry during the 1860s. Its subsequent embodiment in various versions has made it one of the most recognizable icons of science. Based primarily on a symposium titled “150 Years of the Periodic Table” and held at the August 2019 national meeting of the American Chemical Society, this book describes the origins of the periodic law, developments that led to its acceptance, chemical families that the system struggled to accommodate, extension of the periodic system to include synthetic elements, and various cultural aspects of the system that were celebrated during the International Year of the Periodic Table.

Book Description
The historical achievements in organic natural product synthesis can be recognized most clearly in the research accomplishments of Albert Eschenmoser. For example, his work on the chemical synthesis of vitamin B12 defined the frontier in organic natural product synthesis and profoundly influenced the science of organic chemistry. In addition to revealing the beautiful reaction pathways leading to compounds of great biochemical significance, Albert Eschenmoser has contributed innovative methods of outstanding utility for organic synthesis. Few individuals have so fundamentally influenced the science of organic chemistry as Albert Eschenmoser has. Over the years, a sizable fraction of Albert Eschenmoser′s work has been published in Helvetica Chimica Acta, hence the decision of the Editor to produce a special issue of the journal on the occasion of Albert Eschenmoser′s 75th birthday, celebrated on August 5, 2000. The highly impressive set of 67 original research papers submitted in response to the Editor′s invitation could not, for obvious technical reasons, be accommodated in a single issue and were thus divided over the August and September issues. The international reaction to this tribute has been so overwhelmingly enthusiastic that the two issues have been combined in this single volume for separate publication.

Book Description
In the 19th century, pure mathematics research reached a climax in Germany, and Carl Friedrich Gauss (1777–1855) was an epochal example. August Ferdinand Möbius (1790–1868) was his doctoral student whose work was profoundly influenced by him. In the 18th century, it had been mostly the French school of applied mathematics that enabled the rapid developments of science and technology in Europe. How could this shift happen? It can be argued that the major reasons were the devastating consequences of the Napoleonic Wars in Central Europe, leading to the total defeat of Prussia in 1806. Immediately following, far-reaching reforms of the entire state system were carried out in Prussia and other German states, also affecting the educational system. It now guaranteed freedom of university teaching and research. This attracted many creative people with new ideas enabling the “golden age” of pure mathematics and fundamental theory in physical sciences. Möbius’ legacy reaches far into today’s sciences, arts, and architecture. The famous one-sided Möbius strip is a paradigmatic example of the ongoing fascination with mathematical topology. This is the first book to present numerous detailed case studies on Möbius topology in science and the humanities. It is written for those who believe in the power of ideas in our culture, experts and laymen alike.

Book Description
Chemistry as a Game of Molecular Construction: The Bond-Click Way utilizes an innovative and engaging approach to introduce students to the basic concepts and universal aspects of chemistry, with an emphasis on molecules’ beauty and their importance in our lives. • Offers a unique approach that portrays chemistry as a window into mankind’s material-chemical essence • Reveals the beauty of molecules through the “click” method, a teaching methodology comprised of the process of constructing molecules from building blocks • Styles molecular construction in a way that reveals the universal aspect of chemistry • Allows students to construct molecules, from the simple hydrogen molecule all the way to complex strands of DNA, thereby showing the overarching unity of matter • Provides problems sets and solutions for each chapter

Book Description
Kohlenstoff und Wasserstoff - jedem Chemiestudenten sind sie wohlbekannt als Grundbausteine der Organischen Chemie. Welch ungeahnte Vielfalt von Verbindungen sich aus diesen Elementen aufbauen läßt, zeigt dieses einzigartige Buch. Dabei beschränkt es sich nicht nur auf die bloße Darstellung von Struktur und Eigenschaften von Kohlenwasserstoffen, sondern verdeutlicht überdies die Herausforderung, die Moleküle wie Tetrahedran, Superphan oder Dodecahedran an das synthetische Geschick eines jeden Organikers stellen. In seinem Konzept folgt das Werk - retrosynthetische Analyse der Reaktionssequenzen, ausführliche Erläuterung der Synthesemethoden, umfassende Verweise auf die Originalliteratur - dem Bestseller von K. C. Nicolaou und E. J. Sorensen "Classics in Total Synthesis". Es vermittelt so eine Fülle von generellen Prinzipien und Methoden der organischen Synthese und empfiehlt sich auf Jahre hinaus als Standardwerk, das jedem Studenten und Organiker in Forschung und Lehre geläufig sein sollte.

Book Description
This collection explores the role of innovation in understanding the history of esotericism. It illustrates how innovation is a mechanism of negotiation whereby an idea is either produced against, or adapted from, an older set of concepts in order to respond to a present context. Featuring contributions from distinguished scholars of esotericism, it covers many different fields and themes including magic, alchemy, Rosicrucianism, Theosophy, Tarot, apocalypticism and eschatology, Mesmerism, occultism, prophecy, and mysticism.
