AMERICA NEEDSMORE SCIENTISTS* America faces a critical problem-the serious resultof the war's impact upon our supply of scientists.For four years nearly all of our prospective college sci-

ence students were diverted into the armed forces, and thenumber of students majoring in science was drasticallyreduced. Meanwhile, the annual demand for scientistshas grown so rapidly that the supply in this countryis woefully inadequate and will remain so for a longtime unless a definite corrective program is established.Our national security, our industrial and social prog-

ress, our health and happiness-all of which dependlargely on our scientific leadership-are threatened. Sci-entific developments for our future needs must begin withbasic research conducted by properly trained scientists.We must make every effort to increase America's force of

scientific personnel.To this end, we pledge our support in the hope that

scientists, educators, and people in industry can worktogether in stimulating an early interest in science in agreater number of students and thus lay the foundationfor their later specialization.

ries. A bibliography of correlated visual aids is included.

Laboratory Experiments in General Chemistry andQualitative Analysis

By GEORGE W. WATT. International Chemical Series. 225 pages, $2.00This laboratory manual is designed primarily for use in conjunction with General Chemistry, by Schoch, Felsing, andWatt. The selection and order of presentation of experiments are such, however, that the manual may be adaptedfor use with other textbooks. The manual is chiefly concerned with the necessary directions for the conduct of thevarious experiments, and very little background information is included.

A Textbook of Systematic Botany. New third editionBy the late DEANE B. SWINGIE, Montana State College. McGraw-Hill Publications in theBotanical Sciences. 338 pages, $3.50

As before, this textbook presents in logical sequence the principles of plant taxonomy and nomenclature and discussesrepresentative families of plants. The book is applicable to all parts of the country. Most of the chapters have beenthoroughly revised and amplified, some have been almost entirely rewritten, and a new one has been added on methodsof identification.

MATHEMATICAL

METHODS OF

-STATISTICSBy HARALD CRAMER

While British and American statisticians have been de-veloping the science of statistical inference, French andRussian probabilitists have transformed the classical cal-culus of probability into a rigorous and pure mathemati-cal theory. Cramer, a distinguished Swedish statistican,has joined these two lines of development in this masterlyexposition. The first part of the book is an introductionto the fundamental concept of a distribution and of in.tegration with respect to a distribution. The secondcontains the general theory of random variables andprobability distributions, while the third is devoted tothe theory of sampling distributions, statistical estima..tion, and tests of significance.

This is a "now it can be told" storyof wartime research.

It started back in post World War1 days when Dr. Harvey C. Rent-schler, Director of Research for theWestinghouse Lamp Division, andDr. J. W. Marden, an associate, de-cided to determine the melting pointof a rare mineral ... uranium.

In his unending search for an im-proved electric lamp filament, Dr.Rentschler wanted to find out ifuranium would give better servicethan tungsten.So Dr. Rentschler and his associ-

ates worked for about a year beforethey found a way to make pellets ofpure uranium from which the melt-ing point could be determined. Al-though uranium's melting pointmade it unsatisfactory for a lampfilament, Westinghouse continuedto supply tiny amounts of the pre-cious metal to colleges and researchlaboratories for experiments in nu-clear physics.

(Little did they realize that theirknow-how would one day give Amer-ica a head start in the race towardshistory's grimmest goal!)For the most devastating war of

all time had meanwhile blazedthroughout the world-and scien-tists in many countries were fever-

ishly trying to discover a methodfor unleashing the incredible energyconcealed within the atom.

Then, early in 1942, Dr. Rent-schler received a telephone call. Thedirector of the atomic experimen-tation project at the University ofChicago wanted to know how soonWestinghouse could supply threetons ofpure uranium!Dr. Rentschler and his co-workers

immediately went into action. Theysetup a miniatureuranium "factory"in the Lamp Division laboratory-ultimately increasing their produc-tion of pure uranium from 8 ouncesto 500 pounds daily, cutting its costfrom $1,000 to $22 a pound.And within a few months, West-

inghouse had supplied more thanthree tons of the vital metal to theChicago Metallurgical Project Office. . . where the famous "atomic pile"experiments were conducted. Theyalso supplied uranium to physicistsat Princeton University who didmuch to the pioneering work on theatomic bomb.

......It all started as an obscureexperiment to find a betterlamp fila-ment like many another quest forproduct improvement that goes onconstantly in the great Westinghouseresearch laboratories.

But, today, Dr. Rentschler's workof20 years ago is given full credit foradvancing America's atomic bombactivities by at least a year!
