Book Description
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.

Book Description
Arnold O. Beckman was a legend in his time: the blacksmith's son who grew up to play a pivotal role in the instrumentation revolution that dramatically changed science, technology, and society. From his rural boyhood world of farming and woodworking, through his service in the U.S. Marines and his appointment to the Caltech faculty, to his path-breaking creation of the pH meter, the DU spectrophotometer, and the establishment of the Beckman Instruments company, this work portrays an individual whose ingenuity and integrity made him a scientific leader and industrial pioneer. It also discusses his role in California and national politics, and his career as a major philanthropist. Arnold Beckman's story is inseparable from that of the 20th century--a very inspiring read. Included with this biography is a video portrait of Arnold Beckman, in CD-ROM format for both PC and Mac. You will see and hear Dr. Beckman talk about his early life, his marriage to Mabel, and his philosophies of inventing, education, and philanthropy. The CD-ROM was produced by Jeffrey I. Seeman.

Book Description
This new ASIST monograph is the first to comprehensively address the history, theory, and practical applications of citation analysis, a field which has grown from Garfield's seed of an idea, and to examine its impact on scholarly research forty years after its inception. In bringing together the analyses, insights, and reflections of more than thirty-five leading lights, editors Cronin and Atkins have produced both a comprehensive survey of citation indexing and its applications and a beautifully-realized tribute to Eugene Garfield and his vision, in honor of his seventy-fifth birthday.

Book Description
As 2019 has been declared the International Year of the Periodic Table, it is appropriate that Structure and Bonding marks this anniversary with two special volumes. In 1869 Dmitri Ivanovitch Mendeleev first proposed his periodic table of the elements. He is given the major credit for proposing the conceptual framework used by chemists to systematically inter-relate the chemical properties of the elements. However, the concept of periodicity evolved in distinct stages and was the culmination of work by other chemists over several decades. For example, Newland’s Law of Octaves marked an important step in the evolution of the periodic system since it represented the first clear statement that the properties of the elements repeated after intervals of 8. Mendeleev’s predictions demonstrated in an impressive manner how the periodic table could be used to predict the occurrence and properties of new elements. Not all of his many predictions proved to be valid, but the discovery of scandium, gallium and germanium represented sufficient vindication of its utility and they cemented its enduring influence. Mendeleev’s periodic table was based on the atomic weights of the elements and it was another 50 years before Moseley established that it was the atomic number of the elements, that was the fundamental parameter and this led to the prediction of further elements. Some have suggested that the periodic table is one of the most fruitful ideas in modern science and that it is comparable to Darwin’s theory of evolution by natural selection, proposed at approximately the same time. There is no doubt that the periodic table occupies a central position in chemistry. In its modern form it is reproduced in most undergraduate inorganic textbooks and is present in almost every chemistry lecture room and classroom. This first volume provides chemists with an account of the historical development of the Periodic Table and an overview of how the Periodic Table has evolved over the last 150 years. It also illustrates how it has guided the research programmes of some distinguished chemists.

Book Description
The first years of the company that developed the microchip and created the model for a successful Silicon Valley start-up. In the first three and a half years of its existence, Fairchild Semiconductor developed, produced, and marketed the device that would become the fundamental building block of the digital world: the microchip. Founded in 1957 by eight former employees of the Schockley Semiconductor Laboratory, Fairchild created the model for a successful Silicon Valley start-up: intense activity with a common goal, close collaboration, and a quick path to the market (Fairchild's first device hit the market just ten months after the company's founding). Fairchild Semiconductor was one of the first companies financed by venture capital, and its success inspired the establishment of venture capital firms in the San Francisco Bay area. These firms would finance the explosive growth of Silicon Valley over the next several decades. This history of the early years of Fairchild Semiconductor examines the technological, business, and social dynamics behind its innovative products. The centerpiece of the book is a collection of documents, reproduced in facsimile, including the company's first prospectus; ideas, sketches, and plans for the company's products; and a notebook kept by cofounder Jay Last that records problems, schedules, and tasks discussed at weekly meetings. A historical overview, interpretive essays, and an introduction to semiconductor technology in the period accompany these primary documents.

Book Description
"Testicular Cancer" explores the various forms of the disease, discusses its detection, diagnosis, and treatment, and gives an overview of current clinical and laboratory research. This relatively rare form of cancer is seen most often in young men in their late teens, 20s, and 30s. The disease, which once killed most patients, now has a survival rate greater than 90 percent, making it one of the success stories in the history of cancer treatment. Important historical research breakthroughs in the fight against testicular cancer are highlighted, as well as important questions and challenges facing scientists in the future.
