Mathematical

Biologyof Social

BehaviorBy NICOLAS RASHEVSKY. Known forhis brilliant research in the mathematicalfoundations of biology and human be-havior, Professor Rashevsky here enlargeshis theory to include social behavior. Headds a new dimension to social researchby expressing social phenomena as mathe-matical equations derived from postulateson the interaction of individuals amongthemselves and with their environment.The author is professor and chalrman ofthe Committee of Mathematical Biology atthe University of Chicago. $5.00

GenetIc

NeurologyEdited by PAUL WEISS. Here is the firstcollaborative effort to bring together in onevolume the most authoritative views on theprinciples, mechanisms, and causal factorsin the development of the nervous systemand the neural basis of behavior. GENETICNEUROLOGY is a symposium of essayswritten by 19 of the world's foremostauthorities in embryology, neurology, psy-chology, pathology, biochemistry, histology,and related fields, after they had met andcompared their views at a conferencesponsored by the International Union ofBiological Sciences, part of UNESCO. $5.00

What GENERAL ELEIJTRIIJ People Are Saying

E. L. AUYERR. T. HOLLANDApparatus Department

JET NOISE: Since its inception the noiseproblem associated with turbojets has receivedconsiderable attention from the public as wellas from industry. Noise control at test facilitieshas shown some excellent results, but noisecontrol on an installation appears to be im-practical. Since absolute measurements arealways subject to question because of varia-tion in methods of measurement and interpre-tation as well as variations between individualsconcerning discomfort encountered, it is wellto compare a known familiar noise with thenew unknown noise.The public is generallyv familiar with the

noise level associated with conventional air-craft as the aircraft passes overhead. Thereforenoise measurements on the ground were madeas a piston engine aircraft passed overhead andalso as a turbojet airplane passed overhead.Identical methods and measuring equipmentwere used for both tests, and both types of air-craft were operated at normal cruise powersettings.The results ... indicate that noise levels for

the turbojet were actuallv much lower than thenoise levels of the piston aircraft. In additionthe ground observer is subjected to the turbojetnoise for only 20 seconds, while the piston air-craft noise persisted above background levelfor 70 seconds. In both cases the aircraft wereflown directly overhead at an altitude of 1000feet. The same pattern existed for the test madeat 5000 feet.

*A. H. HEMKERApparatus DepartmentFARM POWER: The fact that farmers aredependent on electricity more and more hasbrought to focus the last vear or two a ques-tion: What do you do when the power goesof? . . .Take a dairyman who is milking, say 50

cows. How does he milk them if his milkingmachine won't run? In some cases this mayeven be a physical impossibility. Think of theinconvenience on any farm if the water pumpdoesn't work. If the power interruption is oflong duration, what about the farm freezer?Many farm homes are considerably electrified,and probably the most important electric itemin the farm home is the electric motor that runsthe oil burner or stoker that keeps the homecomfortable.Take the poultrvman who may have chicks

under the brooder or who heats the brooderhouse with an oil or stoker heating plant. Takethe poultryman with a thousand layers or morewho lengthens the working day of his layers byhaving lights in his poultry house. A few in-terruptions in this light cycle would throw hiscomplete flock off production and might evenput them into a molt.Another example of the importance of

electricity is the truck garden or greenhouseoperator who has electric heat in his benchesor who depends on automatic heat with hisstoker to heat his greenhouse. Loss of power inthese cases might mean a loss of considerablemonev.A standby electric power generator is the

answer to the above questions, but I believe itis necessary that we take a sensible view of thefarmer's requirements, even though a farmmay have 20 or 30 kilowatts of connected load.It isn't necessary that he protect himself forhis possible maximum use.... I believe a three-kva generator will take care of most farmers'emergency needs.... I believe in most cases itwould be silly to saddle the farm with a com-plete engine-generator set when the use of itmay average only once a year.... All farmershave a prime mover which is used nearlyevery day.... I am speaking, of course, of thefarm tractor.

Second Edition, revised

METHODS OF

MATHEMATICAL PHYSICS

by Harold Jeffreys and Bertha S. Jeffreys

"The first edition of this important book appeared in 1946. Its pur-

pose was to provide an account of those parts of pure mathematics thatare most frequently used in physics. . . . The authors concentrate on

methods which, in their own wide and creative experience as appliedmathematicians, especially need to be taught. They have achieved a bookthat is unique in making explicit many interesting and useful pointsfrequently overlooked.

"In this new edition appendices have been made integral with the text,and the chapter on multiple integrals has been extended. Among the ad-ditions are: some items on matrices useful in quantum theory, an accountof the theory of functions of several variables, some material on multi-pole radiation. Chapter 17, which deals with asymptotic expansions, is as

good as ever; indeed, it is slightly expanded. I know of no other placewhere the methods of steepest descent and of stationary phase are so

well handled."-American Scientist

"For some research engineers this may be the ultimate mathematicaltoolbox they have been trying to find. A knowledge of calculus is as-

sumed.... The book incorporates the familiar Operational methods andCartesian tensors of one of the authors. This second edition has beenconsiderably revised. This reviewer has noted with pleasure the followingtopics: block matrices, an extended treatment of relaxation methods, a

translation of Heaviside's method into terms permitting one to decidewhat is right and what wrong in it, asymptotic expansions group velocity,and others."
