"Science fiction operates a little bit like science itself, in principle. You've got thousands of people exploring ideas, putting forth their own hypotheses. Most of them are dead wrong; a few stand the test of time; everything looks kind of quaint in hind"

| Radar | ||
| Detection of objects at a distance. |
| A pulsating polarized ether wave, if directed on a metal object can be reflected in the same manner as a light-ray is reflected from a bright surface or from a mirror. The reflection factor, however, varies with different metals. Thus the reflection factor from silver is 1,000 units, the reflection from iron 645, alomagnesium 460, etc. If, therefore, a polarized wave generator were directed toward space, the waves would take a direction as shown in the diagram, provided the parabolic wave reflector was used as shown. By manipulating the entire apparatus like a searchlight, waves would be sent over a large area. Sooner or later these waves would strike a space flyer. A small part of the waves would strike the metal body of the flyer, and these waves would be reflected back to the sending apparatus. Here they would fall on the Actinoscope (see diagram), which records only reflected waves, not direct ones.
 (Radar diagram from Ralph 124c 41+ by Hugo Gernsback) From the actinoscope the reflection factor is then determined, which shows the kind of metal from which the reflection comes. From the intensity and the elapsed time of the reflected impulses, the distance between the earth and the flyer can then be accurately and quickly calculated. |
