Electronics Comes of Age L. V. BERKNER FELLOW AIEE J UST 50 years ago, in the year 1897, Professor J. J. Thomson made the pronouncement, based on clear-cut experimental evidence, of the separate existence of elementary negatively charged particles—electrons. It was in the same year that Guglielmo Marconi suc- ceeded in radio transmission across the Bristol Channel, a distance of nine miles. These events, in a tangible way, highlighted the foundations on which electronics was to be erected: namely, the elementary particles upon which it is based and the external forces or fields produced by these particles in motion. The phe- nomenal developments in electronics in the intervening years mark the emergence of the science and the asso- ciated nation-wide industry of electronics with all the privileges and responsibilities which go with maturity, privileges and responsibilities which have been acquired with growth and expansion ROLE OF ELECTRONICS In every aspect of the basic sciences, we find elec- tronics playing a significant part, either directly or as the catalyst whose presence makes scientific advance feasible. The physicist devises electronic circuits as his "eyes" delve into the nucleus. The chemist deals with electronics in his study of the atom and its valences, of photochemistry, and of a hundred other chemical phenomena. The vista of the geophysicist is enhanced enormously by the tools of electronics in his study of the earth's crust, its interior, and its atmosphere. Until recent times the astronomer could view the sun and the stars in only one octave of light. Now, turning to the broader potentialities of electronics, he can see them over many octaves of electromagnetic radiation. Simi- larly, the medical sciences have acquired a powerful new tool in the electron microscope, a tool which is of equal importance to the metallurgist. In fact, this one element of electronics, electron microscopy, is itself emerging as a whole new branch of science. Electronics, then, serves as a common meeting ground of all the sciences in their reliance upon its applications and devices. The constant references to phases of electronics in the scientific journals attest to this com- mon dependence. But just as science in general is dependent on electronics, so is electronics dependent on science for its growth and nourishment. It is in Esentially full text of a paper presented at the Third National Electronics Con- ference, Chicago, 111., November 3-7, 1947. L. V. Berkner is chairman, section iexploratory geophysics of the atmosphere department of terrestrial magnetism, Carnegie Institution of Washington, Wash- ington, D. C. this symbiotic relationship that the responsibility for regeneration arises. The men of electronics are an especially privileged group, because they have the opportunity to join inti- mately in developments of all of the sciences. The electronics art, and the industry erected upon it, have a distinguished heritage of science and invention. From the general body of organized science and invention there have emerged during the past century and a quarter the men whose work has contributed signifi- cantly and directly to the building of electronics, men such as Faraday, Henry, Maxwell, Bell, Edison, Hertz, J. J. Thomson, Marconi, Lorentz, Braun, and de Forest. However, as always, with privilege goes responsibility. The men of electronics are expected to derive from their cultural inheritance, and from their association with the development of all the sciences, new creative im- pulses and a freshness in point of view which will ensure the constant vigor and growth in the field of electronics that are so essential to both science and industry as a whole. A DEFINITION What is electronics? It is perhaps too bold to off'er any concise definition for such a diverse science, but one can say that electronics is the science that deals with the motion of electrically charged particles in a field of force and with the forces or fields developed by such particles as a consequence of their motion. Simi- larly, the electronics industry is that branch of industry (primarily) dependent upon electronic phenomena. Of course, the scope, implications, and potentialities of a science and industry so simply defined are extra- ordinary. Especially striking is the facility with which the advances in electronic science have been translated, through a virile industry, to applications of great benefit to mankind. But there are still many, many unsolved problems of vital importance for which electronics seems to offer a solution. Can the science and industry continue to meet this challenge adequately? Can electronics continue its growth in maturity to achieve the untold promise which some hold for it, or will it, like Buridan's ass in the debate of the medieval scholastics, come to rest by a balance of internal motiva- tions and propulsions? BACKGROUND It has been said that the daily mode of life of our grandfathers was closer to the days of Julius Caesar 32 Berkner—Electronics Comes of Age ELECTRICAL ENGINEERING
