Dieses Lehrbuch vermittelt dem Leser alle wichtigen, chemischen Grundlagen, die in der Biologie von Bedeutung sind. Jeder, der selber kein Chemie gelernt hat, kann hier alles über jene chemischen Strukturen einfach nachlesen und verstehen, die relevant sind, um komplexe Sachverhalte in der Biologie nachzuvollziehen. Die Themen umfassen Elemente (Atombau und Periodensystem), Chemische Verbindungen, Ionenverbindungen, Säuren und Basen/ Redoxreaktionen, Systematik organischer Stoffe, Kondensationsreaktionen, Ablauf chemischer Reaktionen.

Antoine Lavoisier’s great accomplishments include the discovery of oxygen’s role in combustion, helping to develop the metric system, writing the first extensive list of elements, helping to reform the nomenclature of chemistry, and the discovery that while matter may change shape through chemical reaction its mass remains the same. It is for these extraordinary accomplishments that he is often referred to as the “Father of Modern Chemistry.” Some scholars argue that this moniker is more the result of self-promotion and that his discoveries relied heavily on the work of others, nonetheless his impact on advancing this field of science cannot be understated. «Elements of Chemistry» was first published in 1790 and is largely concerned with the chemistry of combustion. While modern students of chemistry might find the work limited in its scope, the historical impact of its publication cannot be understated. The experiments contained within helped to lay the foundation for the understanding of the role of oxygen, hydrogen, acids, and alcohols in chemical reactions and its emphasis on quantitative analysis and instrumentation helped to establish the use of chemistry as a legitimate science for understanding and defining the physical world.

For many years, Leonard A. Ford, formerly Chairman of the Division of Science and Mathematics at Mankato State College, Minnesota, devised «chemical magic» shows for a series of college science fairs. In response to many requests, he compiled a volume of over 100 novel demonstrations from those shows. The book soon became one of the most widely used manuals in the field. Its tricks, mystifying and often spectacular, were designed not only to amuse and entertain an audience but to stimulate an interest in scientific principles.Now, with this revised and enlarged republication of Dr. Ford's classic guide, students at both high school and college levels can learn to perform a wide variety of entertaining and educational chemical magic. Here is a dazzling array of stunts and demonstrations dealing with gas liberation, color changes, fires and combustion, smoke and vapors, polymerization, specific gravity, crystallization and precipitation, and many other chemical processes. Professor Ford provides clear and careful explanations for creating cold fire, a disappearing flame and dust explosions; dissolving a glass in water; turning water to milk and back again to water; producing mysterious balloons, heavy air, and magical eggs; and carrying out scores of other intriguing «tricks» with materials available in almost any school laboratory, supply house, or home. Training and experience in handling chemicals are required for the performance of these demonstrations. Dr. Ford outlines directions and safety precautions for each trick. In addition, he supplies helpful suggestions for a line of «patter» to use during performances.Newly revised and updated by Professor E. Winston Grundmeier, this absorbing and unusual book will be welcomed by science educators at the high school and college levels as well as by sponsors of youth and church groups, service clubs, science fairs, and other organizations.

"Chemistry, in particular, is capable, when suitably presented, of making a strong appeal to the intelligence and the imagination; for, as the following pages are intended to show, it is the most romantic of all the branches of science; and in its variegated history, stretching back through unnumbered generations of alchemists into an indefinite past, its present votaries have (if they but knew) a richly human and humanistic heritage." — from the PrefaceWritten for the layman, this accessible history takes a broad, humanistic perspective, eschewing chemical equations and formulae. Instead it concentrates on the great figures of chemistry and the ideas that revolutionized the science, from earliest history to the modern era.Much of the book is devoted to alchemy and such topics as the philosopher's stone, alchemical crypticism and symbolism, pseudo-alchemists, Paracelsus, and the «swan song» of alchemy as the scientific revolution took hold. In the final chapters, the author takes up the development of modern chemistry, including atomic theory, the nature of the elements, the beginning of organic chemistry, and more. Broad in scope, erudite yet readable, this rich and absorbing narrative will appeal to anyone interested in the long and colorful history of chemical science. Glossary. 50 illustrations.

One of the greatest experimental scientists of all time, Michael Faraday (1791–1867) developed the first electric motor, electric generator, and dynamo — essentially creating the science of electrochemistry. This book, the result of six lectures he delivered to young students at London’s Royal Institution, concerns another form of energy — candlelight.Faraday titled the lectures «The Chemical History of a Candle,» choosing the subject because, as he explained, «There is not a law under which any part of this universe is governed which does not come into play and is not touched upon [during the time a candle burns].»That statement is the foundation for a book that describes, with great clarity, the components, function and weight of the atmosphere; the function of a candle wick; capillary attraction; the carbon content in oxygen and living bodies; the production of carbon dioxide from coal gas and sugar; the properties of carbonic acid; respiration and its analogy to the burning of a candle; and much more. There is also a chapter comprising Faraday's «Lecture on Platinum.»A useful classroom teaching tool, this classic text will also appeal to a wide audience interested in scientific inquiry.
