OUR COVER

Apart from the correct alloying of the various metals used in its composition one of the most important phases in the manufacture of Anisotropic Alnico magnet steels is that of heat treatment. Our cover illustration shows one of Rola Company's physicists removing a white hot magnet from the laboratory furnace (left) and placing it between the poles of a powerful electro-magnet in which it will be cooled and made Anisotropic.

THE IMPORTANCE OF ELECTRONICS

FOR too many years now has the importance of electronics been overshadowed in the public mind by the entertainment value of one of its greatest manifestations — radio broadcasting. It is only natural that this, one of the marvels of the century, should capture the public imagination to the extent that it has done, but at the same time there is no reason why kindred, and even more important branches of electronics, should be relatively so little known. The vast part played in the world's economy by radio communication (as distinct from broadcasting) is hardly even guessed at by the layman. Radio communication itself is now only one item in an ever-growing list of electronic applications, the importance of which, is daily increasing. In the last decade, uses have been developed for electronic techniques which were previously undreamed of. Industrial men, doctors, engineers and workers in all branches of pure and applied science, have been provided with powerful new tools for investigating and solving their problems — problems which, in many cases, have defied solution till electronics supplied the key to them. To some, this may seem a sweeping statement, and so it is, but it is nonetheless true, and in direct proportion to its truth is the importance of electronics to the world at large and to this country in particular. This being the case, the importance of having a sufficiently large body of men trained in electronics engineering can hardly be overestimated. At present a vicious circle exists, whereby the full exploitation of electronic techniques is hindered by the lack of men with good enough qualifications and sufficiently advanced training. The incentive to suitable young men to study advanced electronics is likewise hindered by the lack of positions for them once they are fully trained. However, there is certainly no lack of appreciation in Great Britain or America, either of scientific development generally, or of electronics in particular. It is recognized that in defence alone electronics will, in the future, play a part bigger by far than its share in the last war. For this reason alone, quite apart from any other, Australia should take care to keep in the forefront of peace-time electronics, just as she did during the war. For, whether peace or war is to be our future lot, we now live an electronic age, when none can say that this branch of applied science will not ultimately exceed all others in its effects upon mankind.
