P-ETROLEUM MICROBIOLOGYby Ernest Beersteeher, Jr.

Associate Professor of Biochemistry, University of Texas.The marriage of petroleum engineering and bacteriology has

produced a problem child, virtually reared in secrecy and, asyet, even unnamed. Whatever the ultimate name of this un-ruly offspring-biogeochemistry, microbiological exploration,or petroleum microbiogene-this realng new book tellsits Bfe story as concerns the oil Industry. This is a storynever beore told in its entirety and It has great bearing onthe exploration drilling, producing and refining of oil.Petroleum Microbiology is a fd o s vitaf importancethat it has been said that it is the "Coming Technique in The

Oil Business".The volume contains both theory and instructions on how

to accomplish specific results. It cover the technique of microbiolog n exploration, in behavior and treating of drilligmuds, in water flooding during secondary recovery operaions,In combatting electrolytic corrosion, in the catatic problemsof refining.

In fact Petroleum Microbiology is a mwut'for every petro-leum enneer regardless of his specific field, for not only willit asst him in his day-to-day problems but for many it wilopen the door to an entirel new fiela of knowledge.Order this neow volume new.

A businessman looks at ethics and sociail philosophy

BY CALES MAYERUILDING on a naturalistic basis, this eminent French biochem-ist, huimanist, and man of letters presents his own solidly realisticview of -the ethical problems of today's world. He believes in

progress, in enlightened self interest, in free competition; and it isIthin this framework that he believes altruism and ratinal ethicshave their place. He.rejects the idea that all men are equal and isstrongly opposed to the "coddling of the weak and inefficient," eco-nomic planning, the Welfare State. But he insiset that opportunitymust be equal, that progress can be made only by free individuals,not by regimented societies.

ON MICROCARDSFollowing the requests of a number of li-braries, the AAAS Board of Directors hasdecided to publish a microcard edition ofSCIENCE. The 1953 issues are now availablein this form. The space saving is considerable.25 sets of 3" x 5' microcards take up ap-proximately the same space as one set of thebound volumes of SCIENCE for 1953. The'bother and expense of binding is completelyeliminated.

The cost of the Microcard edition for1953 has been set at $15.00 and it is antici-pated that the Microcard edition of subse-quent years will sell at the same price. Ordersfor the 1953 edition and standing ordersmay be placed with: AAAS, 1515 Massachu-setts Avenue, NW, Washington 5, D. C.

What General Electric People Are Saying...J. P. DITCHMANMr. Ditchman is with the Lamp Division". . . Light-fundamental to farm production-is becoming the key to farm-crop control.Scientific use of lighting promises more startlingbenefits for mankind than some other areas oftechnology that are much more publicized.Although the relationship of light to life has

long been known, only recently have welearned enough about the way light enters thelife process to apply it commercially. Just a fewapp lications have begun to multiply the pro-ductive capacity on the farms, but what hashappened so far has convinced many scientistsand businessmen that great things are ahead.Even the farmer is having difficulty maintaininghis customary reserve.When you realize that almost minute quanti-

ties of light may be adequate to affect plants'blooming time, it becomes important to studyenvironments carefully to prevent upsetting tb,,-delicate balances. Not so long ago an electricsign upset the dark cycle of poinsettia plantsinside a greenhouse. The grower was luckythough; it was discovered in time so that he wasable to meet the Christmas trade. However, amink ranch didn't fare so well; floodlighting inthe vicinity completely upset the breeding cycleof the mink resu ting in expensive losses.As our experience broadens, we may well be

prepared to extend what we know about familiarproblems to the newer, less familiar ones. Mostof us naturally think of lighting in terms ofhuman uses. The lightmeter is calibrated forhuman seeing and film sensitivity. But in dealingwith light for plants, animals, insects, fish, fowl,and gamc, we must think in terms of only thespecific energy relevant to each. In a sense, apoultryman must look through the eyes of hischickens. Such completely varied problems inthe field must be approached differently-andrarely from the human's viewpoint.

In this vast field, there's much more to findout. Each day we learn how to make more andbetter food for the undernourished peoples ofthe world. Our gains in the past two decadeshave been tremendous. The future holds muchpromise.

G. E. Review

C. H. LINDERMr. Linder is Vice President in charge of Engineering"... We are moving today, I believe, in industryand education, toward a common area of agree-ment on what constitutes the right kind ofeducation. Industry, which in the past mightrightly have been accused of sometimes takinga narrow view of the proper goals of education,is taking a broad-gauge view. We are increas-ingly recognizing the need for people who havehad an education that has both variety anddepth in engineering, science, and the humani-ties.Most certainly in industry, particularly in our

technical work, we need people who are edu-cated, not just informed. Any attempt on thepart of a secondary school, and more particu-1arly a college or university, to give instructionin current engineering practice rather than atraining in the basic principles is doomed tofailure from the beginning if for no other reasonthan that technology is changing and shiftingso rapidly.With the increase in volume and complexity

of our technology, the need for geople in engi-neeringand applied science with a vanceddegreeshas become greater and, in my opinion, duringthe years that are immediately ahead our econ-omy is going to require a continued increase inthe percentage of our technical people withadvanced degrees.

It is my belief that many of the engineeringcurricula are going, during the coming years, totend to include a larger and more significantelement of training in applied science ratherthan in many of the design or engineeringpractice courses now included. Industry doesnot expect the secondary schools and collegesto create specialists in specific knowledge, butrather all-round well-trained people who haveunderstanding of basic principles. As individualsfind interest and challenge in specific areas thespecialists we need will become available.
