Radioisotopes a new dimension for applied science

IT GOES WITHOUT SAYING that a look back over the past 25 years will show great changes in every branch of the applied sciences and especially in electrical engineering. Generators, transformers, switchgear, and transmission lines, for example, are designed today to operate at greater capacity, with increased reliability, more automatically, and at higher voltages than did their predecessors of 1934 vintage. Such changes, broadly speaking, are in the nature of improvements and constitute the development of electrical engineering as an art progressing as it has throughout the entire 75-year history of the AIEE. With this long history, it is no wonder that future electric machinery and equipment development can be forecast with some degree of accuracy.
