COLUMN MOST READERS of ANALYTICAL CHEMISTRY will have noted by
now that several changes were made in the January issue of the journal, concomitant with the changing of editors. Logotypes for the principal features of the advertising section of the journal were changed with a view to greater uniformity throughout the book and for increased visual clarity. The January issue also contained the first monthly author index to research papers, and this will remain a permanent feature of the journal. This should be welcomed by readers who in the past have complained about the necessity of "thumbing through" the pages or consulting the lengthy title contents pages of current issues for the work of a particular author. The yearly author and title indexes will, of course, be retained in the December issues and, when practical, cumulative indexes will be made available. In an effort to expand the coverage of important analytical events, the editors hope to have more summaries of important meetings—as, for example, the summary of the 1965 Gatlinburg Conference which was prepared by advisory board member J. C. White and D. A. Costanzo for this issue (see page 130A). This issue of the journal also carries a new quick-reference table for those courses which offer continuing education for the analytical chemist (seepage 129A). Mixed Feelings on Computers Some 200 scientists at the Brookhaven National Laboratory were recently questioned about computers, and the majority took practical and resolute positions with regard to the computer's role in their work. The dissenters felt that

computers tempt researchers to seek and accept immediate numerical results for specific problems instead of underlying scientific laws. The survey was undertaken by Dr. Robert J. Spinrad of Brookhaven, and results were reported in the December 1965 issue of Physics Today. At least two interesting patterns of response were revealed by the survey: (1) There is a correlation between the scientist's age and his use of the computer (older men tend to use them less), and (2) there is a much lower commitment of medical and biological researchers to computer-aided studies than of physicists. In the case of scientists over 40, their lack of familiarity with computer programming is probably connected with their reluctance to use them. Most of these men were well into their professional careers when the computer age arrived; nevertheless, over 90% of those polled wanted some or all of their students to learn how to program computers. Those scientists most knowledgable about computer capabilities and operation through extensive experience predicted the greatest increase in use in their respective fields. Others, on less intimate terms with computer techniques, felt that growth of computer use would either keep pace with their fields or fall behind. The dividing line between proponents and critics was sharply drawn on the question of whether computers injure thinking. The responses ranged from "Computer studies of a biological subject tend to make one organize the problem better" to "Perhaps computers do not induce sloppy thinking but provide massively greater opportunities for revealing it." As the survey's author, Dr. Spinrad is of the opinion that "the use of computers in science is just emerging from a tempestuous adolescence with the promise of a rounded, healthy maturity still before it."
YOUR ROUND-BOTTOM FLASKS 1'T FLY OUT OF THIS NEW NEST.
The Fisher-Bean Flask Holder (patent pending) is the first really new laboratory holder since Fisher introduced Castaloy®-R clamps—and it's just as handy. It holds any kind of round-bottom flasks, distilling flasks, Kjeldahl flasks—you name 'em. Flasks can't get bumped out or knocked over. Strong, springy stainless steel fingers grip the body of the flask tightly, hold it securely in any position . . . even upside down! It gives you an extra hand, since you can pick up flask and holder together, one-handed. (Cork and rubber rings can go into the discard.) Use a few Fisher-Bean Holders to make a drying board—every last drop will run out. Put 'em under the bench to make an out-of-the-way, upsidedown storage rack. Five sizes fit all round-bodied flasks from 50 to 2000 ml capacity: they're listed below.
