INTRODUCTION TO RANDOM SIGNALS AND NOISEBy Wilbur B. Davenport, Jr. and William L. Root, Massachusetta Institute of Technology.Lincoltl Labora-

tor" Publications. 393 pages,$11.00.

An introduction to the tatistical theory underlying a study of signals and noi es in communications systems.Empha is is placed on technique a well as result. Parts of probability theory "and the modern theory of ran-dom processes are developed in a way suitahle for an engineering reader. This material is applied to give acoherent treatment of many basic communications engineering noise prohlems. The chief departure in treat-ment i the replacing of variousad hoc methods of treating random signals and noise hy aconsistent set ofmethods from the theory of random processes.

AN INTRODUCTION TO STATISTICAL COMMUNICATION THEORYBy David Middleton. McGraw·Hill Internationai Series in Pure and Appli~d Physics.1140 pages,$25.00

Covers important mathematical aspects of large-scale, complex automatic control system . Discusses feedbacktheory; matrix methods; numerical analysis; linear integral equations; basic statistical theory; systemsanalyses in phase space; analy i of sampled-data systems; and much more.

INFORMATION TRANSMISSION, MODULATION AND NOISE

A Unified Approach to Communication SystemsBy Mischa Schwartz, Polytechnic Institute of Brooklyn.McGraw·Hill Electricai and Electronic Engineering

eries. Brooklyn Polytechnic Institute Series.454 pages, $11.00.

A senior or first-year graduate level text which stresses the basic unity inherent in modern information trans-mi sian of information-nan-zero time response or finite bandwidth and noise. The significance of these twolimitations is explored in a representative group of modulation systems. There are approximately 250 prob-lems ranging from simple numerical exercises to detailed step-by-step problems which extend the material inthe text. .

MISSILE AERODYNAMICSBy Jack N. Nielsen, VIDYA, Inc.McGraw-Hill Series in Missile and Space Technology.450 pages, $12.50

This volume presents a rational and connected account of principles of missile aerodynamics. It treats thesubjects of bodies, wings, and tails and the interactions between them which are particularly important formi siles. Various methods are presented for determining the airflow about missiles, including the vorticeswhich are frequently very prominent in the flow.

GAS PURIFICATIONBy Arthur L. Kohl and Fred C. Riesenfeld, both of the Fluor Corporation, Ltd.McGraw·Hill Series in Chem-

ical Engineering. 556 pages,$15.00 .

This book provides a practical engineering description of techniques and processes which are widespread inu e. Subject matter is limited to the removal from gas streams of gas-phase impurities which are presentinrelatively minor proportions. Space has been allocated on the hasis of apparent importance to industrywithgreatest stress on those processes which are common to more than one field.

A Problem Deflector

FROMB. C. OELHEIM,'46:I was excited when reading the article oneducation in: the last issue to reach me,and have shown it to our two teachersfrom England who are teaching about 20American children in seven of the firsteight grades in one room.

We are a group of about 200 Americanssituated in a small Spanish community.We are learning to live with our mostcourteous hosts and for all of us it is aworthwhile experience we shall neverforget.

An idea which I pass along to you issuggested by a weather-vane type winddeflector which I have-rplaced on top ofour chimney, and which permits us touse our fireplace, today, in a very highwind. (Without the deflector we wouldhave hot ashes blown all 'over our livingroorn.) I wish that all of us might employa similar deflector for all of our problemsin life and accept each Dew problem asan incentive to our thinking and as achallenge to our inventive genius. Whycan't we use all of our atomic wastematerial just as fast as it accumulates?

Corporation.

Professor Guillemin came toM.LT. from the University of Wis-consin, and later received hisdoctorate from the University ofMunich. He was an assistant andinstructor in the Electrical Engi-neering Department before becom-ing an assistant professor in 1928,an associate professor in 1936, andprofessor of electrical communica-tions in 1944. He was a generalconsultant to the Radiation Labo-ratory from 1940 to I 945. He is aFellow of the American Institute ofElectrical Engineers, and theauthor of Iruroductory Circuit'Theory (John Wiley and Sons, Inc.,1953).

Creating a strange world of cold

The coldest natural temperature ever recorded-IOO degreesbelow zero :""-occurredin the Antarctic. But the people of Union Carbide areproducing temperatures all the way down to minus 450 degrees ... approach-ing absolute zero!

')

Startling things are being done atthis unearthly cold tempera-ture. Many types of living tissue are being preserved, and research is now wellunder way in freezing whole blood. Certain metals become perfect conductorsof electricity -a rare quality which may bring greater efficiency to electronicequipment. And, fOJ;over fifty years, Union Carbide has used these ultra-lowtemperatures toturn air into liquid ... then extract oxygen, argon, nitrogenand other atmospheric' gases in their pure form. They are produced on amammoth scale to meet the great demand from industry.

) ,

Working with such extreme cold is still a young science knownas cryogenics.It is only one of many areas in which the people of UnionCarbide are striving to make tomorrow a b~tter world.

Management AcademyPROFESSOR Emeritus Erwin HSchell. '12, of the M.LT. School ofIndustrial Management. was a dele-gate to the International Academyof Management's meeting inAWl.

tralia, which was addressed byJames R. Killian, Jr., '26, Chairmaof the M.IT. Corporation. Fifteenhundred representatives of 29 na-tions were expected to attend this12th meeting of theComite Inter-national de l'OTganisation Sci en·tifique, known as CIOS.

Professor Schell is chancellor ofthe International Academy of Man-agement, an 'honorary societyformed in 1957, and was to partici-pate in ceremonies honoring inter-national managers. The Academyrecognizes contributions to man-agement through work, vision, val-ues, and beliefs in a free society byselecting 10 Fellows each year. Healso was invited to speak at theUniversity of Melbourne.

Librarian EmeritusALTHOUGH Miss MargueriteChamberlain's retirement is re-ported in the M.LT. librarian'sannual report, she is still workingat the Institute part time, and con-cerning herself especially with theenlargement of the mathematicscollection.

Miss Chamberlain 'came to M.I.T.to organize the science library inMarch. 1932. She says now thatshe has organized it "Shespends hertime "trying to keepup with it:'In the early days, she recalls, theInstitute was small enough so thata librarian knew everyone who pa·tronized the library and what hedid. In May, 1952, Miss Chamber-lain, along with the science library,moved from the Eastman Libraryin Building 6 to the new Haydenbuilding. J "There's' much moremovement and bustling abouthere," she says. "In fact it's a bitlike doing business on Main Street."

After graduating from Colby Col-lege in Maine with a B.A. degree,Miss Chamberlain taught for threeyears before continuing her studiesat Simmons, held various libraryposts, and finally came to M.l.T.

OPTIC NERVE FOR EYES THAT SEE100 FEET BELOW THE SURFACE

This is a television camera. Its job is to photograph the substrataof excavations, thereby providing information needed by engineersin planning the construction of Boston's new Prudential Center, amodern, multi-million dollar real estate development.

Here in the Back Bay section of Boston, with its artificially main-tained water table, this sealed camera must go down into a water-filled hole 100 feet below the surface. To transmit the picture fromthe camera to the surface monitor, Lake Service Corp. of Brighton,Massachusetts, designers and manufacturers of the television equip-ment, chose Simplex Anhydrex XX insulated cable because of itsability to withstand the rigors of submarine and direct burial duty.

For all types of service involving high and low voltages, whetheraerial, underground or submarine, or for everyday plant wiring, itpays tocall a Simplex Engineer.
