#electromagnetic

For in 1900 all electromagnetic radiation of longer wavelengths was already known at least to the extent that one could not seek in it the more striking characteristics of X-rays such as, for example, the strong penetrating power. ↗

At the head of these new discoveries and insights comes the establishment of the facts that electricity is composed of discrete particles of equal size, or quanta, and that light is an electromagnetic wave motion. ↗

For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta. ↗

We, and the universe we live in, produce and operate in a sea of natural and unnatural electrical and magnetic fields. The earth, for example, pulses at about 10 Hz, like a small engine. Our bodies, as you may remember from chapter 1, are really electromagnetic machines. We simply can't move a muscle or produce a thought without an electrical impulse - and wherever there is electricity, a magnetic field is also produced, which is why we link the two together into one word: electromagnetic."

#electromagnetic #emf #microwaves #zapped #nature

The entrance to the natural EM senses is now guarded by artificially monstrous EM waves carrying every kind of pattern irrelevant to nature, from TV sitcoms to defense radar broadcasts. It is as though we have covered the whole surface of the globe with a slum of slovenly, impalpable constructions during the past eighty years or so since Marconi. They are literally skyscrapers in as much as they touch the ionosphere and are reflected from it. They are tenements full of the disorderly displays of sitcoms and the sterile reflections of military radar. ↗

#em-pollution #transmissions #nature

Some may wonder whether part of the harvest of this invisible pollution (electromagnetic radiation) may be the comparative rarity of visionary experience in the modern world, and the predominence of a removed, overanalytical, repelling 'onlooker' intelligence in its place, resembling that of the (Martin) Amis hero (who will not see because he cannot feel). If this is so, such an intelligence has produced conditions favoring its evolution and survival. ↗

I joined the Army and was sent to the MIT radiation laboratory after a few months of introduction to electromagnetic wave theory in a special course, given for Army personnel at the University of Chicago. ↗
