Now Lorentz has endeavoured to find the conditions in which the electromagnetic theory proposed by him might agree with the postulate of the complete impossibility of determining absolute motion.
In the case of the Great Pyramid, the object is the perceived unit entity which as perceived remains self-identical throughout the ages; while the whole dance of molecules and the shifting play of the electromagnetic field are ingredients of the event. An object is in a sense out of time.
The wonders of the motion picture, of radio, of television, of radar, of the photo-electric cell-the all-seeing "electric eye," of atomic energies, are all based on the electromagnetic phenomenon of light. The motion picture art can portray any miracle. From the impressive visual standpoint, no marvel is barred to trick photography.
There are no cylinders to be shaved; all that is needed to use the wire again is to pass a magnet over it, automatically erasing any previous record that you do not wish to preserve. You can dictate into it, or, with this plug in, you can record a telephone conversation on it. Even rust or other deterioration of the steel wire by time will not affect this electromagnetic registry of sound.
When two or three transmitters are each sending out their electromagnetic waves, the result, naturally, is utter confusion." White added that the British Postal Administration was refusing to grant licences for more than one system in the same area, in spite of the fact that there had been some 'alleged' solutions of the problem.
The space-time theory and the kinematics of the special theory of relativity were modelled on the Maxwell-Lorentz theory of the electromagnetic field. This theory therefore satisfies the conditions of the special theory of relativity, but when viewed from the latter it acquires a novel aspect.
What has just been described is always, in some form, one of the indispensable parts of the electromagnetic machines used in industrial electricity, and in all of them except the appliances of electric lighting, and even in that case it is indispensable in producing the current which consumes the points of the carbon, or heats the filament to a white glow.
Wendigee's contrivances for detecting and recording any disturbances in the electromagnetic conditions of space are singularly original and ingenious. And by a happy combination of circumstances they were set up and in operation about two months before Cavor made his first attempt to call up the earth. Consequently we have fragments of his communication even from the beginning.
Regular physical exercise means increased blood supply, improved nutrition and better drainage for all the vital organs of the body. By means of systematic exercise, combined with deep breathing, the liberation and distribution of electromagnetic energies in the system are also greatly promoted.
When we look at the sun we wish to know something about the sun itself, which is ninety-three million miles away; but what we see is dependent upon our eyes, and it is difficult to suppose that our eyes can affect what happens at a distance of ninety-three million miles. Physics tells us that certain electromagnetic waves start from the sun, and reach our eyes after about eight minutes.
