I"LEMENTARY THEORETICAL FLUID MECHANICS, by Karl Brenkert, Jr. 348 pages, diagrams, 6 X 9 in. New York, John Wiley & Sons, Inc., 1960. Price, $7.50. This new text covers the basic topics of fluid mechanics, with emphasis on the derivation and application of the fundamental equations. A knowledge of the calculus is a prerequisite, since it is used in many of the proofs. The eight chapters deal with: (1) definitions and concepts; (2) fluid statics; (3) conservation of matter and the Euler equation; (4) momentum and angular nmmentum; (5) conservation of energy; (6) friction; (7)dimensional analysis and model study; and (8) potential flow. Problems are given at the end of each chapter and one of the appendices consists of a list of references for further study. RUNNERLESS MOLDING, by Ernest P. Moslo. 162 pages, illustrations, 5 X 7} in. New York, Reinhold Publishing Corp., 1960. Price, :$4.95. :\ concise survey of the theory, design, applications and economics of runnerless molding is provided in this sinai[ text. It describes in detail the various techniques of injection molding accomplished without the removal of a sprue and runner system on each injection molding shot. The author has included discussions of such recent developments as precompression and sequential molding. Many explanatory drawings show the actual construction of nozzles used for runnerless molding, minifolds and mold equipment. The book is primarily directed to the plastics and related industries by demonstrating the ways in which runnerless molding may be employed to eliminate sprue scraps, cut labor costs, minimize rejects and greatly speed production.
POLYSTYRENE, by William C. Teach and George C. Kiessling. 176 pages, illustrations, 5 X 7 in. New York, Reinhold Publishing Corp., 1960. Price, $5.00. This book gives a simplified yet technically accurate introduction to the chemistry, properties, manufacture and uses of polystyrene. The greater emphasis throughout the text is on the applications of polystyrene materials by injection molding, by extrusion, by vacuum forming, and as a foam. The latest information has been included on the uses of poly-

styrene in appliances, electronics, building, packaging, housewares, toys and novelties, shoe heels, transportation, and furniture. An entire chapter is devoted to the manufacture, fabricating, techniques and various uses of expandable polystyrelm. A large amount of the material will be of interest to research workers, such as a new approach to the evaluation of the effects of polymerization temperature on molecular weight and new information on the copolymerization of styrene and alphamethylstyrene. However, it is directed primarily to molders, fabricators and end-users of polystyrene. INTERNATIONAL MISSILE AND SPACECRAFT GUIDE, by Frederick I. Ordway II[ and Ronald C. Wakeford. v.p., illustrations, 8½ X 11 in. New York, McGraw-Hill Book Co., Inc., 1960. Price, $25.00. In their preface, the authors state that "The Guide is not a primer on rocketry; it is, rather a handbook on specific missile systems." The authors make good their word, for the Guide covers four types of modern missiles (surfaceto-surface, surface-to-air, air-to-surface, and air-to-air), rocket airplanes, manned missiles, spacecraft, research rockets, drones, and space-research vehicles in eleven countries. It also describes the history of rocket development, including an invaluable chronological table of missile progress, dating from 1200 to 1959. Many rare photographs add to the presentation. Data are included on launchings, warheads, operational uses, servicing, field maintenance, test programs, and technical specifications. Arranged by countries, the information is readily accessible. The Guide is an extensive and accurate survey; as such, it is a re~d contribution to space technology. HANDBOOt¢ OF SUPERSONIC AERODYNAmCS. VOLUME 6, SECTION 18, SHOCK TUUES, by I. I. Glass and J. Gordon Hall. 604 pages, diagrams, 8 X 10{ in. Washington, U. S. Government Printing Office, 1959. Price, $3.75. This definitive work on shock tubes lives up to the standards of excellence set by other sections of the Handbook. Intended as a practical reference for scientists and engineers concerned with the design and performance of supersonic vehicles, Section 18 is composed

BOOK NOTES
of seven chapters, including a very brief introductory one. The six main chapters deal with: Performance of Simple Constant-Area Shock Tubes (one-dimensional rarefaction, plane shock waves, the wave system, etc.); Observed Flows in a Constant-Area Shock Tube (boundary layer effects, wave speed measurements); Production of Strong Shock Waves (attenuation, the diaphragm shock tube); Applications of the Shock Tube (as a wind tunnel, in aerophyslcs research, hightemperature gas physics); and Shock-Tube Flow Measurement and Instrumentation. An abundance of graphs, tabular material and diagrams supplements the text. A list of 114 references (all but eight covering the last twenty years) is included. THE THEORY OF THIN ELASTICSHELLS,edited by W. T. Koiter. 496 pages, illustrations, 6 X 9 in. New York, Interscience Publishers, Inc., 1960. Price, $9.00. This volume is the proceedings of a symposium held in Delft, Holland, in August 1959. Sponsored by the International Union of Theoretical and Applied Mechanics, the symposium consists of 23 papers (17 in English, 5 in German and 1 in French) dealing with: the general equations of shell theory; buckling and nonlinear theory of spherical, cylindrical and conical shells; analysis of helicoidal shells; nonsymmetrical deformations of hyperboloic paraboloid, spherical and cylindrical shells; membrane theory of developable shells and of shells of positive curvature; and dynamics of thin shells. INTRODUCTIONTO LINEAR PROGRAMMING,by Walter W. Garvin. 281 pages, diagrams, 6 X 9 in. New York, McGraw-Hill Book Co., Inc., 1960. Price, $8.75. As indicated in the title, this is an introductory treatment of linear programming, intended as a text for a one-semester course. Eighteen chapters are divided into three main parts: The General Linear-Programming Problem; The Transportation Problem and Its Variants; and Special Methods. In Part I, the simplex method is developed, and details of the computational procedure are described. Part II covers a specialization of the simplex method, and devotes some space to such subjects as the caterer problem, the assignment problem, the tanker-routing problem, and the
[J. F. I.
generalized transportation array. In Part I I I, tile author deals with special methods and some of their applications, for example, the revised simplex method, parametric linear programming, duality and the warehouse problem. Several of the chapters (for example, the generalized transportation problem and statistical linear programming) have not, until now, been included ill such a text. NOISE REDUCTION,edited by Leo L. Beranek. 752 pages, illustrations, 6 X 9 in. New York, McGraw-Hill Book Co., Inc., 1960. Price, $14.50. Noise control is fast becoming a major problem for the nation, in aircraft, home appliances, automotive vehicles, airports, etc. In an effort to conquer the problem, M.I.T. offered summer courses in noise reduction in 1953, 1955, 1957 and 1960. The present volume draws heavily oil the material presented at those summer courses. The book is divided into four parts covering sound waves and their measurement, fundamentals underlying noise control, criteria for noise and vibration control, and practical noise control. The book covers fundamental principles of sound transmission, techniques of acoustical measurement in several kinds of environment, methods of controlling noise, and case histories of practical noise control. The book can be read with profit by graduate engineers in nearly any technical field. DIGITAL COMPUTERS AND NUCLEAR CALCULATIONS, by Ward C. Sangren. 208 pages, diagrams, 6 X 9 in. New York, John Wiley & Sons, Inc., 1960. Price, $8.50. The author has written this book for nuclear scientists and engineers, in order to acquaint them with the uses of high-speed calculations in the design and application of nuclear reactors. The first four chapters form an introduction to nuclear reactors, digital computers, programming, and numerical analysis. The last four chapters discuss actual reactor calculations, under the following titles: A Code for Fission-Product Poisoning; Diffusion and Age-Diffusion Calculations; Transport Equatlon--Monte Carlo; and Additional Reactor Calculations (kinetics, burnout, etc.). A useful bibliography, arranged by chapters, also includes a list of nuclear code reports.
