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-on demonstrations 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!

Chemistry explores the way atoms interact, the constitution of the stars, and the human genome. Knowledge of chemistry makes it possible for us to manufacture dyes and antibiotics, metallic alloys, and other materials that contribute to the necessities and luxuries of human life. In Transforming Matter, noted historian Trevor H. Levere emphasizes that understanding the history of these developments helps us to appreciate the achievements of generations of chemists. Levere examines the dynamic rise of chemistry from the study of alchemy in the seventeenth century to the development of organic and inorganic chemistry in the age of government-funded research and corporate giants. In the past two centuries, he points out, the number of known elements has quadrupled. And because of synthesis, chemistry has increasingly become a science that creates much of what it studies. Throughout the book, Levere follows a number of recurring themes: theories about the elements, the need for classification, the status of chemical science, and the relationship between practice and theory. He illustrates these themes by concentrating on some of chemistry's most influential and innovative practitioners. Transforming Matter provides an accessible and clearly written introduction to the history of chemistry, telling the story of how the discipline has developed over the years.

Reacting to the perception that the break, early on in the scientific revolution, between alchemy and chemistry was clean and abrupt, Moran literately and engagingly recaps what was actually a slow process. Far from being the superstitious amalgam it is now considered, alchemy was genuine science before and during the scientific revolution. The distinctive alchemical procedure--distillation--became the fundamental method of analytical chemistry, and the alchemical goal of transmuting "base metals" into gold and silver led to the understanding of compounds and elements. What alchemy very gradually but finally lost in giving way to chemistry was its spiritual or religious aspect, the linkages it discerned between purely physical and psychological properties. Drawing saliently from the most influential alchemical and scientific texts of the medieval to modern epoch (especially the turbulent and eventful seventeenth century), Moran fashions a model short history of science volume

Alchemy, the Noble Art, conjures up scenes of mysterious, dimly lit laboratories populated with bearded old men stirring cauldrons. Though the history of alchemy is intricately linked to the history of chemistry, alchemy has nonetheless often been dismissed as the realm of myth and magic, or fraud and pseudoscience. And while its themes and ideas persist in some expected and unexpected places, from the Philosopher's (or Sorcerer's) Stone of Harry Potter to the self-help mantra of transformation, there has not been a serious, accessible, and up-to-date look at the complete history and influence of alchemy until now.
