Chemical Heritage

This book traces the global chemical history of cannabidiol (CBD), which is a compound that originates partially from hemp (the fiber), marijuana (the popularized term for medicinal/recreational use), and cannabis (the species sativa). It also argues about the position that CBD is in today and the heritage established by chemists over the course of its development. Each term associated with the plant spans centuries of development and cross-culturally became an object of cultivation and commerce. Humans have explored cannabis’ complex chemical possibilities with the hope that it would offer pain relief or some type of mind-numbing portal to other existences. As such the trio and their many incarnations have been and will continue to be an integral part of the past, the present, and the future. Known as cannabis compound cannabidiol (CBD), a non-psychoactive component of the drug, it is one of some 100-plus known cannabinoids; offshoots of the original plant that are isolated and, in some cases, chemically altered. Just as with any supposed pharmaceutical marvel, chemists are at the center of this narrative. In order to understand its historical roots, central to CBD’s discovery was the efforts of scientists who worked in separate eras and regions. These included, Americans Roger Adams and Allyn Howlett, and the Bulgarian-born Israeli chemist Raphael Mechoulam, along with a throng of others. They influenced a generation of students and changed the face of cannabis research into the 21st century. What does its history tell us about the future of chemical products like CBD? This brief will explore the chemical heritage that formed across a complicated nexus of global events. These are the bonds that tie.

Von der Alchimie zur modernen Chemie, von der Kunst des Goldmachens zur Moleküldynamik und chemischen Großproduktion: Verfolgen Sie die Entwicklung einer geheimnisvollen Kunst zur Naturwissenschaft! Der Autor trug Dokumente und Illustrationen aus über 400 Jahren zusammen; die Abbildungen sind ganzseitig und von hervorragender Qualität. Lebendig, interessant, informativ! (05/00)

The essential, cornerstone book of modern environmentalism is now offered in a handsome 40th anniversary edition which features a new Introduction by activist Terry Tempest Williams and a new Afterword by Carson biographer Linda Lear.

A collection of photographs and biographical information intended to help teachers present "the human face of science. ... The format and special binding of the book allow for easy conversion to overhead transparencies."--Cover.

In this brief, Mary Virginia Orna details the history of color from the chemical point of view. Beginning with the first recorded uses of color and ending in the development of our modern chemical industry, this rich, yet concise exposition shows us how color pervades every aspect of our lives. Our consciousness, our perceptions, our useful appliances and tools, our playthings, our entertainment, our health, and our diagnostic apparatus – all involve color and are based in no small part on chemistry.

This book was designed to help teachers supplement science curricula with human stories of discovery in the chemical sciences. Chemical Achievers presents the lives and work of two types of achievers. First are the historical greats, those chemical scientists most often referred to in introductory courses. Second are those scientists who made contributions in areas of the chemical sciences that are of special relevance to modern life and the career choices students will make. The human faces summarized in this book range from Robert Boyle to Glenn Seaborg and Stephanie Kwolek. In this lively and comprehensive collection of photographs and biographies, Bowden illuminates how much the chemical sciences owe to the individual achiever. Over 150 images can be easily reproduced as overhead transparencies or other visual teaching aids.

Understanding the Periodic Table of Chemical Elements is critical for success in the chemistry classroom and laboratory. In today's classroom, students not only need to understand the properties of the chemical elements, but how these elements play such an integral role in industry, the earth and the environment, and in modern life. No resource provides a better introduction than Robert Krebs's The History and Use of Our Earth's Chemical Elements. In this thoroughly revised edition, with extensive new examples on the importance of the chemical elements, the elements are examined within their groups, enabling students to make connections between elements of similar structure. In addition, the discovery and history of each element - from those known from ancient times to those created in the modern laboratory - is explained clearly and concisely.
