he history of chemistry is a story of human endeavor-and as er- T ratic as human nature itself. Progress has been made in fits and starts, and it has come from all parts of the globe. Because the scope of this history is considerable (some 100,000 years), it is necessary to impose some order, and we have organized the text around three dis- cemible-albeit gross--divisions of time: Part 1 (Chaps. 1-7) covers 100,000 BeE (Before Common Era) to the late 1700s and presents the background of the Chemical Revolution; Part 2 (Chaps. 8-14) covers the late 1700s to World War land presents the Chemical Revolution and its consequences; Part 3 (Chaps. 15-20) covers World War I to 1950 and presents the Quantum Revolution and its consequences- and hints at revolutions to come. There have always been two tributaries to the chemical stream: experiment and theory. But systematic experimental methods were not routinely employed until the 1600s-and quantitative theories did not evolve until the 1700s-and it can be argued that modem chernistry as a science did not begin until the Chemical Revolution in the 1700s. xi xii PREFACE We argue however that the first experiments were performed by arti- sans and the first theories proposed by philosophers-and that a rev- olution can be understood only in terms of what is being revolted against.

In this fascinating history, Cathy Cobb and Harold Goldwhite celebrate not only chemistry's theories and breakthroughs but also the provocative times and personalities that shaped this amazing science and brought it to life. Throughout the book, the reader will meet the hedonists and swindlers, monks and heretics, and men and women labouring in garages and over kitchen sinks who expanded our understanding of the elements and discovered such new substances as plastic, rubber, and aspirin. Creations of Fire expands our vision of the meaning of chemistry and reveals the oddballs and academics who have helped shape our world.

Science popularizer Cathy Cobb takes a unique approach to explaining the concepts of physical chemistry by telling the story of the geniuses and eccentrics who made groundbreaking discoveries in this fascinating field that bridges chemistry, physics, and mathematics. The result is entertaining and illuminating.Her tale is about the colorful varieties of human character as well as the struggles to understand the workings of the material world. Through true stories of rebels, recluses, heroes, and rogues, she helps the reader to discover how one idea built upon another and how an elegant discipline arose out of centuries of difficult trial and error.Starting with the ancient Greeks, Cobb takes the reader on a sweeping tour of history. She shows how an understanding of basic chemical properties gradually arose out of ancient Greeks mathematics, Muslim science, medieval "magick," and the healing arts. Her tour continues through the scientific revolution, the emergence of physical chemistry as an independent discipline, and up to the present. Today, physical chemists contribute to the fields of chemical physiology, chemical oscillations and waves, quantum mechanics, and the curious and promising field of nanotechnology.This absorbing, eloquently written history of science is loaded with intuitive imagery, everyday analogies, and a colorful cast of characters who are guaranteed to entertain as well as edify.

With hands-on demonstrations, this book presents the science - and the realities - of forensic chemistry in a narrative style that makes this timely topic accessible to the nonchemist. The authors lead you through actual and simulated forensic techniques, such aspresumptive and confirmative drug testing,body fluid identification including luminol testing,DNA analysis,trace fiber and gun shot residue analysis,latent fingerprint development, and forensic soil analysis.Through more than twenty-five demonstrations, using ordinary household products and items, you can become familiar with the basics of forensic chemistry and gain insights into the painstaking work that goes into criminal investigations and is rarely seen on TV. If you're a fan of true-crime stories or mystery fiction, or interested in the science behind dramas like CSI, this informative and entertaining book is a must-have addition to your library.

This book challenges the perception of chemistry as too difficult to bother with and too clinical to be any fun. Cathy Cobb and Monty L. Fetterolf, both professional chemists and experienced educators, introduce readers to the magic, elegance, and, yes, joy of chemistry. From the fascination of fall foliage and fireworks, to the functioning of smoke detectors and computers, to the fundamentals of digestion (as when good pizza goes bad!), the authors illustrate the concepts of chemistry in terms of everyday experience, using familiar materials.The authors begin with a bang-a colorful bottle rocket assembled from common objects you find in the garage-and then present the principles of chemistry using household chemicals and friendly, nontechnical language. They guide the reader through the basics of atomic structure, the nature of molecular bonds, and the vibrant universe of chemical reactions. Using analogy and example to illuminate essential concepts such as thermodynamics, photochemistry, electrochemistry, and chemical equilibrium, they explain the whys and wherefores of chemical reactions. Hands-on demonstrations, selected for their ease of execution and relevance, illustrate basic principles, and lively commentaries emphasize the fun and fascination of learning about chemistry.This delightful and richly informative book amply proves that chemistry can appeal to our intuition, logic, and-if we're willing to get down and dirty-our sense of enjoyment too.

A unique approach to the history of science using do-it-yourself experiments along with brief historical profiles to demonstrate how the ancient alchemists stumbled upon the science of chemistry.Be the alchemist! Explore the legend of alchemy with the science of chemistry. Enjoy over twenty hands-ondemonstrations of alchemical reactions.In this exploration of the ancient art of alchemy, three veteran chemists show that the alchemists' quest involved real science and they recount fascinating stories of the sages who performed these strange experiments. Why waste more words on this weird deviation in the evolution of chemistry? As the authors show, the writings of medieval alchemists may seem like the ravings of brain-addled fools, but there is more to the story than that. Recent scholarship has shown that some seemingly nonsensical mysticism is, in fact, decipherable code, and Western European alchemists functioned from a firmer theoretical foundation than previously thought. They had a guiding principle, based on experience: separate and purify materials by fire and reconstitute them into products, including, of course, gold and the universal elixir, the Philosophers' stone. Their efforts were not in vain: by trial, by error, by design, and by persistence, the alchemists discovered acids, alkalis, alcohols, salts, and exquisite, powerful, and vibrant reactions--which can be reproduced using common products, minerals, metals, and salts. So gather your vats and stoke your fires! Get ready to make burning waters, peacocks' tails, Philosophers' stone, and, of course, gold!
