patents for the electrolytic production of aluminum were not issued until April 2, 1889, his famous discovery occurred on February 23, 1886 (program 19); and PaSteur'S mechanical resolution involved sodium ammonium raeemate not the free acid (program 9). Hoffmann and his collaborators have admirably succeeded in their goals of delineatingchemistry as a human activity motivated by curiosity and in demonstrating its relevance to modern life. I warmly recommend their series not onlv to colleae students and their instructon but also to anyone curious ahout the banir principles of "the central srrence" and rts role in our society. George B.

In these days of r i s i i and often misdirected public concern about synthetic chemicais in water supplies and foodstuffs, chemistry teachers are likely targets of questions about the ~esticidesand herbicides in common use. Here is an authoritative, conveniently collected set of status reports on 50 compounds with potential for causing adverse health effects in exposed humans. These are substances that already have been found in drinking water or are likely candidates for such contamination. The materials are listed alphabetically by generic names with CAS No., structural formula, synonyms, uses, properties; environmental fate, pharmokineties, health effects, analytical methods, and treatment technologies. The hook would better serve the needs of novitiates if there were an index of the synonyms. Not all of us remember that Sevin, a pesticide widely used in family gardens, also is corbaryl, the identification in this Health Advisory. This omission may retard quick searching of the book, hut it doesn't lessen the great d u e of the provided information once it is located. Malcolm M. Renfrew University of Idaho MOSCOW. ID 83843

This author is a good storyteller and provides a thoroughly interesting report on the chemistry he learned a t Harvard and what he had to learn elsewhere in experiences around the world that early on t w k him to Peter Debye's laboratory in Leipzig. His own professional development mirrors the rise of graduate education in our field over

60 years in which he hecame an important contributor with early textbooks on statistical thermodynamics and electrochemistry. He rose through the academic ranks at Northwestern University, retiring from there to hecome Robert A. Welch Emeritus Professor of Chemistry at Baylor University. More recently, he has been a distinmished member of the Santa Clara Vallev ~ C section S and has served as a consultant for laboratories in that area. Dole departedfrom the academic scene to take part in the Manhattan Project during the wsr years. His research interest in polymer chemistry, especially in radiation effects, led to industrial consultantships with commercial application of his hasie findings. He also takes pride in his experimental detection of differences in the atomic weights of oxygen in air and watcr that l ~ d to the change in the atomic weight scalenow bawd on 12Crather than oxygen. Arnonx the many cheerful anecdotes is Dole's pursuit on his bicycle of a young man who had lifted his wallet from a hip pocket. Recovery of the wallet led to nation& news coverage. In Waco the local paper headlined "Baylor Chemistry Professor Dissolves Robbery Attempt"; elsewhere thieves were warned not to mess around with Dole. Chemistry teachers and their students will gain educational values from this b w k scientifically. It also will serve as a worthy model for clarity in composition. Malcolm M.

When former students visit me, the parts of my lectures that they invariably recall most vividly are my lecture demonstrations, usually the more spectacular ones, even though in some cases more than three decades have elapsed. Indeed, the "live" lecture demonstration is a most effective means of communication, even in this era of film, television, and other varieties of "canned" media. According to Charles Taylor, Professor of Experimental Physics a t London's Royal Institution and Emeritus Professor of Physics at the University College, Cardiff, Wales, "It seems to work with all age groups andis a great way of inculcating a sense of excitement about science, especially in children". In 1985 the Royal Society established a special commission to study the problem of increasing the public's understanding of science, a problem which has been discussed and debated widely in the wake of the rampant epidemic of chemophobia that is sweeping the United States and other developed countries. In the committee's report (Thepublic Understanding of Science; The Royal Society: London, 1985) the scientific establishment of the United Kingdom gave full approval to the presentation of lecture demonstrations to juvenile audiences and provided the impetus for Taylor's latest book, which incorporates the substance of the Gregynog Lectures that he delivered a t Volume 67

the University College of Wales, Aberystwyth during 1987-1988. In the "Prologue" Taylor states, "My principal purpose [in writing this hook] is to encourage teachers and lecturers once again to consider the technique [of lecture demonstration, the use of which has lately experienced a decline] seriously and to take the time and trouble to illustrate their lessons and lectures. Since I am a physicist I have confined my illustrations to physics, but most of the principles discussed apply equally well whatever branch of science is being taught." Like Gaul, Taylor'svolume is divided into three parts. Part 1, "The Growth of the Art" (47 pp), examines the history of demonstrations from the time of Pythagoras to the nresent dav. with details of some of the famous demo&trations of the past (by John Tyndall, John Theophilus Desaguliers, Thomas Young, Sir Humphry Davy, Michael Faraday, Sir James Dewar, Hermann von Helmholtz, D. C. Miller, Sir W. Lawrence Bragg, etc., who are limned in biographical sketches) that can still be used very effectively. It also includes several examples of more recent demonstrations, including those on television. Part 2, "The Science behind the Art" (38 pp.), considers in detail the prohlems of transferring information from the lecturer to the audience (the psychology of lecturer-audience interactions). It also SUNeys various types of teaching aids which may compete with or complement demonstrations (slides, tapeslide combinations, closed-circuit television, video recording, video discs, and microcom~uters)and deals with the most nse.-.........-.-.-

into a demonstration lecture. Part 3, "?he Practice of the Art" (68 pp), the longest part of the book, deals with the crucial, practical details of presenting a successful demonstration lecture such as hints on how to get started, care in presentation, choosing the correct apparatus size, coping with disasters, taking a lecture on tour, how to keep the attention of an audience varying in age from 7 to 70, audience participation, and safety. This copiously illustrated hook is replete with photographs or drawings of historical equipment and manuscript notes. The "Epilogue" (4 pp) discusses the future of the lecture demonstration and the all-important need to increase the public understanding of science and technology. A list of references (3 pp), datingfrom 1709 to 1987; an index of demonstrations (3 pp, 58 demonstrations), classified as "visual aids using nonconventional apparatus," "analogue demonstrations," and "real experiments;"and aname and subject index (5 pp) conclude this lucid, entertaining, highlyrecommended, and most attractively priced collection of reminiscences, advice, recipes, and experiences by "a master of the lecture demonstration," as 1967 Nobel chemistry laureate Sir George Porter calls the author in his foreword. During the last few years a number of hooks of lecture demonstrations have appeared, of which I have reviewed the following: Shakhashiri, Vols. 1, 2, & 3, J. Chem.

This is the revised and updated second edition of The Art of Electronics, designed as a text and reference on electronic circuit design, hoth analog and digital. The book emphasizes the methods actually used by circuit designers-a combination of some basic laws, rules of thumb, and a large bag of tricks. The result is a largely nonmathematical treatment that encourages circuit intuition, brainstorming, and simplified calculation of circuit values and performance. This new edition includes totally rewritten chapters on microcomputers and microprocessors, substantially revised chapters on digital electronics, on a m p s and precision design, and on construction techniques. Every table has been revised, and many new ones have been added.

With the accelerated growth of the chemical industry in recent years, there has been a steady rise in human, material, and property losses because of chemical accidents. Fires, explosions, hazardous and toxic spills, as well as equipment failures and a multitude of other mishaps, have increased the risks to employees, to society in general, and to the environment. This hook examines the subject of accident and emergency management from industrial, regulatory, and educational perspectives. Detailed examples of actual proceduregfrom simple lower explosive limit calculations to complete hazard and risk assessment case studies-complement much of the material presented. Following an expanded introduction to the accident and emergency management area, this book explains the technical jargon, basic theory, calculational principles, and process design considerations associated with accidents, with particular emphasis on the chemical process industry. It then deals with the issue of chemical dispersion in the atmosphere after fire- or explosion-related accidents and concludes with the quantitative metbads used in hazard and risk assessment, prefaced by an introduction to the mathematical prohahilities on which these methods are based.

The primary goals of this hwk are to enrich conceptual understanding, to develop thinking, and to integrate infurmation. The contributors Look at how students' learning can he improved through conventional formal writing and also through regular informal writing to advance, not just test, understanding. Essays in the book's first three sections identify broad problems and possibilities in using writing to learn, and then turn a t once to classroom application: what works and why. The final two sections move from classroom practice to departmental programs and look at the role of writing in the larger ecology of learning. The book will he a resource to graduatelevel instructors of presewice math and science education courses, where it can also serve as a supplementary text; to inservice math and science teachers, particularly at the college and secondary levels; and to all faculty and administrators involved in "writing across the curriculum" programs and workshops.

Included are numerous and widely differing examples of applications taken from chemistry, biophysics, biochemistry, and polymer science. Examples of practical applications are liquid crystal displays and sheet polarizer manufacturing. The hook does not require an extensive prior knowledge of mathematics or quantum theory, but rather outlines the hackground theory and describes the experimental techniques used to achieve partial molecular orientation and to perform optical measurements in a simple way.
