There are plenty of activities for the user in the context of the concepts being covered. Each part would he a n appropriate pre-lab exercise for organic experiments in which the techniques are used. In order tojudge the value of a pmieet such as the one reviewed purchaser m i s t ask a t least two, fundamental here, each questions: (11 Who are the users? and (21 Why would they use it? The orice (vide infra) oreeludes the ourchase of it by individual students. Therefore, h e instruetort~lmust decide kow to integrate such a product into the course and when and how to use it. It is fruitful to review some advantages and disadvantages of a project that calls itself comprehensive. Interactive software has advantages over a book because it paints students in the right direction, gives them context-sensitive feedback on solving problems, and lets them assimilate material at a pace they can handle. This project chwses general and fundamental topics that should appear in everyone's euniculum from what traditionally would be two year-long courses. A student could potentially go to thme topics for a n alternative view of how to lmk at that subject when it is being covered in her or his dass. The disadvantage is that the material is organized differently from the bwk being used, and at the intmductory level, the students do not know which topics to review. One way to use this software is to "assign" sections from it along with reading and questions from the book. Comprehensiue Chemistry will he extremely valuable in this regard. I t will help students learn how to solve same afthe problems that also appear in the hook by leading them through the problems step-by-step. In this way it also will instill same self-confidence. In my opinion, Comprehensive Chemistry is not a good reference book in the traditional sense, even in the way same of the commonly used texts might be. I also don't believe that it was intended to be. There is just no simple and consistent way to get a definition, a statement of some chemical law or principle, or a quick summary an a topic out ofthis software. That is not tosay that you could not learn that definition, rule, or ~rincipleby using this software. I believe that the approach used by the authors is a quite effective way to learn the material. However, it is not a summary of everything one should know about these subjects. In various places within this project, the authors use the scientific method to establish a principle or answer a question. This is accomplished by presenting problems in which the student collectsdatain a series of "experiments" and then must draw a conclusion or identify an unknown. It is a very effective method on a computer especially with video visualization. For example, one examines the relationship between pressureP and temperature T by measuringp a t various temperatures and then platting the data. The linear relationship and the concept of absolute zero are quite obvious even if the experiments are not "real." In another case, the saluhility of same salts are reviewed by looking at video clips of the mixing of certain anions and cations. Subsequent ta that, an unknown is assigned (with four salts as possible solutions1The student designs the experiments by mixing the unknown with various known solutions and actually observing the vidmtaped outcomes. That's a very realistic method by which a student not only learns the material but also the pmcess by which shehe got there! The vendor, Falcon Software, claims that 'Were are 180 hours of interactive instruction." That claim is certainly justified, although it didn't take me quite that long. Because Comprehensive Chemistry contains so much material, a list of even minor concerns or shortcomings might get long. I would place all of my reservations in that catemrv " * lexceot oerhaos the oroblems that amse because of the meed of m v mm~uters'ilrmessors):the" are minor. Commehensive ~~
Given the price and a potential purchasers reservations, one may want a complete outline of the programs' content to see which topics are or are not covered. These are not currently provided, hut the vendor or authors might be convinced to do this.

Chemistry Imagined: Reflections on Science Roald Hoffrnann and Vivian Torrence. Smithsonian Institution Press: Washington, DC, and London, England, 1993. Figs., diagrams, photographs, and 30 color plates. 168 pp. 20.0 x 25.2 cm. $19.95. In this u n q u r nmalgnm d a r t , srlcncc, and lrterarurr. 1981 Sobe1 lnurr3tr cl~erntst;and prrscnter of the P I E l r l e ~ , ~ i l ocourse. n "The M'urld of Chrmutr,:" Ranld Hoffmann. and nrtid \',wan Florig h r r e n c e have collaborated to produce a coherent set of images (30 full-page, full-color collages created during the period 1989-1991 by Torrence) and matching essays-factual or scientific, philosophical or historical-or poems (Hoffmann's contributions range in length from two to five pages and include 57 line drawings) evoked hy these images. Although such a venture is unusual today, the histancal precedent for this activity can be found in Andrea Alciato's Emblematn Flumen Abundans, a collection of symbolic pictures and explications. Published in Renaissance Italy (1531), this Latin work was followed by hundreds of so-called '"emblem books." Evolving from Hoffmann and hrrence's meeting in 1986 a t the Djerassi Foundation, "Chemistry Imagined has as its subject "the maeic of chemistrv-its historical mots. the richness of activities of ma&m chemistry, the waysof knowkg of this central science." However, it is not only a trade book but also a travelingexhibition, which, since its opening in November 1991 a t the Des Moines Art Center, has appeared a t the Purdue University Galleries, Indiana University's Fine Acts Gallery, Augusta College, the New York Academy of Sciences, the Douglas Drake Gallery, the Beckman Center for the History of Chemistry, the National Academy of Sciences, the National Institutes of Health, and Cornell University's Herbert F. Johnson Museum of Art. Through its pairing of different media, the bwk presents an insightful and innovative lmk a t the creativity of chemistry and reveals that chemistry, like art, is a creative process, a fact well known to scientists but not sufliciently appreciated by the general public, far whom the volume is intended. Collaee. the medium introduced in the 1910's by Picasso and Braque andadopted by Torrence, breaks up the common path of thinking as a logical, commonsense process and demands that we seek new, unexpected relationships and use our intuitive as well as logical faculties, much as both artists and scientists do. lbrrence and Hoffmann thus demonstrate that although the arts and sciences appear to live largely in different worlds, there is chemistry in art and art in chemistry. Torrence's provocative images and Hoffmann's perceptions of ancient and modern chemistry combine to produce a multifaceted humanistic vision of the spirit, wander, and essence of chemistry that makes a n inexpensive, ideal, and beautiful gift for scientists, artists, students, and the general public As a n example of popular science a t its best, it is a welcome addition to the arsenal of weapons to combat chemophobia and antiscientific attitudes so prevalent in today's society.
