Experiments – forgotten, but pretty
First of all, the author wishes to present to the reader the most ancient of his experiments. It is possible that some of this will interest you.
Radio receiver under the hood
So, we take a conventional radio receiver on batteries, set it to any wave and output the volume to the maximum. The receiver (see Fig.) Is located on a high dielectric stand, approximately in the center of the cavity of the structure, made up of several steel, cast-iron and aluminum pipes. The diameter of the inner tube is 30 cm, the height is 50 cm. From above and below all this is tightly closed now with steel plates of 50 mm, with the addition of aluminum and brass shields.
The structure is grounded.
As we conserve the receiver, the wave gets lost, and, instead of pleasant music, we hear only white noise.
According to all the provisions of physics, no external radio waves are able to break through to the oscillatory circuit of the receiver.
With the help of a simple device, a transformer and two discharge electrodes, we form an electric spark. The receiver will immediately respond with a characteristic creaking change in the tone of the noise.
What happened? After all (we will open the textbook of physics) even so-called. called the Faraday grid, incomparable with thick-walled metal screens, according to scientists, successfully absorbs the entire spectrum of radio waves.
Assumption 1. Electrons in a metal simply do not have time to synchronize their own reciprocating motion with incoming waves. But, only in this way they screen the radio wave.
Assumption 2. The receiver superheterodyne itself emits radio waves. Reflecting in a confined space, the waves constantly rebuild the oscillatory circuit. Thus, the receiver every minute runs through the entire range of settings, and is able to receive radio waves that have penetrated through the shielding screen.
Assumption 3. The electric spark and the oscillating circuit of the receiver, in this position, randomly emits radio waves, are similar to each other. Objects that have approximately the same spectrum of radiation – absorption communicate with each other in a special way, in addition to the laws of physics known to science. Changes in one object (A) are immediately responded to in another (B).
The receiver with autonomous power is in a steel earthed cylinder. The spark discharge penetrates the metal layers.
Speed and gravity. Empirical research
Imagine that you have an orange in your hand. If you find the power to throw it parallel to the surface of the Earth at a speed of 8 km. with., he will become a companion of our planet and, somewhat simplistically speaking, will lose weight.
Suppose you dropped the fruit at a rate of only a few meters per second. The effect of reducing weight again, will take place, although these changes are measured in fractions of a milligram.
Imagine now that your friend is throwing an orange back. Both of you are standing on a platform of sensitive scales. Will, for the time of this game, the system you-friend-orange, in general, easier?
The simple becomes very complex very quickly. Some additional, more obvious schemes represent that “yes.”
All physical bodies consist of a myriad of “oranges” – elementary particles. The average velocity of oscillatory motion of the latter, at twenty degrees Celsius, is about three hundred meters per second. As the temperature increases, the speed of movement increases.
So, we can expect that with a decrease in body temperature (in a closed system), its weight will increase slightly. And, with increasing T, the pressure on the support will gradually disappear.
To calculate more accurately, it is necessary to combine some formulas for bodies moving along a circle, and also the dependence of the velocity of molecules (acting here as “satellites”) on temperature. Friends, I once did all this, but after so many years from the time of the failed publication in “TM”, much has been forgotten. Try it yourself. The result, in general, is quite interesting. I myself did not conduct full-scale experiments, but I used the data, alas, to measure the body weight of a person before and after his death. The difference is about 10 grams (weight is added).
And the results of calculations, for a body weighing 80 kg, cooling down from 40 C, to 20 C, fully correspond to this.
Experiments with a flywheel unwinding to a certain speed are also known. The weight of the top is reduced.
In this case, the movement of the orange, sorry, is closed in a ring. Nothing more, in fact, does not change.
