Of what lasting benefit
has been man's use of science and of the new instruments which
his research brought into existence? First, they have increased
his control of his material environment. They have improved his
food, his clothing, his shelter; they have increased his security
and released him partly from the bondage of bare existence. They
have given him increased knowledge of his own biological processes
so that he has had a progressive freedom from disease and an
increased span of life. They are illuminating the interactions
of his physiological and psychological functions, giving the
promise of an improved Science has provided the swiftest communication between individuals; it has provided a record of ideas and has enabled man to manipulate and to make extracts from that record so that knowledge evolves and endures throughout the life of a race rather than that of an individual. There is a growing mountain of research. But there is increased evidence that we are being bogged down today as specialization extends. The investigator is staggered by the findings and conclusions of thousands of other workers - conclusions which he cannot find time to grasp, much less to remember, as they appear. Yet specialization becomes increasingly necessary for progress, and the effort to bridge between disciplines is correspondingly superficial. Professionally our methods
of transmitting and reviewing the results of research are generations
old and by now are totally inadequate for their purpose. If the
aggregate time spent in writing scholarly works and in reading
them could be evaluated, the ratio between these amounts of time
might well be startling. Those who conscientiously attempt to
keep abreast of current thought, even in restricted fields, by
close and continuous reading might well shy away from an examination
calculated to show how much of the previous month's efforts could
be produced on call. Mendel's concept of the laws of genetics
was lost to the The difficulty seems to be, not so much that we publish unduly in view of the extent and variety of present-day interests, but rather that publication has been extended far beyond our present ability to make real use of the record. The summation of human experience is being expanded at a prodigious rate, and the means we use for threading through the consequent maze to the momentarily important item is the same as was used in the days of square-rigged ships. But there are signs of
a change as new and powerful instrumentalities come into use.
Photocells capable of seeing things in a physical sense, advanced
photography which can record what is seen or even what is not,
thermionic tubes capable of controlling potent forces under the
guidance of less power than a mosquito uses to vibrate his wings,
cathode ray tubes rendering visible an occurrence so brief that
by comparison a microsecond is a long time, relay combinations
which will carry out involved sequences of movements more reliably
than any human operator and thousand of times as fast - there
are plenty of Two centuries ago Leibnitz invented a calculating machine which embodied most of the essential features of recent keyboard devices, but it could not then come into use. The economics of the situation were against it: the labor involved in constructing it, before the days of mass production, exceeded the labor to be saved by its use, since all it could accomplish could be duplicated by sufficient use of pencil and paper. Moreover, it would have been subject to frequent breakdown, so that it could not have been depended upon; for at that time and long after, complexity and unreliability were synonymous. Babbage, even with remarkably generous support for his time, could not produce his great arithmetical machine. His idea was sound enough, but construction and maintenance costs were then too heavy. Had a Pharaoh been given detailed and explicit designs of an automobile, and had he understood them completely, it would have taxed the resources of his kingdom to have fashioned the thousands of parts for a single car, and that car would have broken down on the first trip to Giza. Machines with interchangeable parts can now be constructed with great economy of effort. In spite of much complexity, they perform reliably. Witness the humble typewriter, or the movie camera, or the automobile. Electrical contacts have ceased to stick when thoroughly understood. Note the automatic telephone exchange, which has hundreds of thousands of such contacts, and yet is reliable. A spider web of metal, sealed in a thin glass container, a wire heated to brilliant glow, in short, the thermionic tube of radio sets, is made by the hundred million, tossed about in packages, plugged into sockets - and it works! Its gossamer parts, the precise location and alignment involved in its construction, would have occupied a master craftsman of the guild for months; now it is built for thirty cents. The world has arrived at an age of cheap complex devices of great reliability; and something is bound to come of it.
