Isaac Asimov, speaking of robots, wrote a novel back in 1940 enunciating his "three Laws of robotics". They remained at the center of discussions among scientists for a long time. Something has already been promulgated by the U and recently, but we are still far from transposing the contents of the laws designed by Asimov ; just think of the drones employed on the battlefield and their artificial intelligence. How sad!!

Let's take a 5-6 year old child from our evolved society and let's put him to live in a tribe of men and women who live the simplest everyday life: the search for food, the construction of a shelter and stay alive until the next day. In short, the child will acquire all the essential notions to live in that environment. He will never know what is the stock exchange, cryptocurrencies, space exploration, plane travel etc. For him, the roar of two planes facing each other in a duel for political or economic domination does not represent the clash between those who are right and those who are wrong, it is Moderna curiosity; yet he was born in an evolved family, highly civilized and well integrated in modern society. The environment is therefore the determining factor, the environment is the one from which we have moved away and now that this begins to no longer respond to our parameters ( lots of water, lots of sun, no rain etc.) we realize that our desires do not respect the needs of life on the planet ( sun, clouds, wind, rain, snow, the speed of life both plant and animal.) Less gold and more environment; right! We only have this spaceship with its habitat and it must be carefully maintained if we want to continue living with all other animal and plant species. Simplicity and learning to hear the voices of Planet Earth.

Some useful information about microwaves. Every day our body is reached by energy flows: photons and all the charges and pulse that exceed the Van Halen fascias. Here are some news related to microwaves . I totally agree about indeterminate dangerousness of 5 G. an example comparison. If we put a frog in a pot of boiling water it will jump out, but if we heat the water slowly it will not have the strength to save itself. We humans are the Frog, microwaves are water, and the stove is our evolved civilization. There's something to think about. Microwaves are a type of electromagnetic radiation, as well as radio waves, ultraviolet radiation, rays raggi Microwaves have a wide range of applications, including communications, radar and, perhaps best known to most people, the kitchen. Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies. This wide range of wavelengths is known as the electromagnetic spectrum (EM spectrum)., The spectrum is generally divided into seven regions in order of decreasing wavelength and increasing energy and frequency. Common designations are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), raggi Microwaves fall within the range of the EM spectrum between radio and infrared light. The electromagnetic spectrum, from the highest to the lowest frequency waves., (Image credit:) microwave ovens have frequencies ranging from about 1 billion cycles per second, or 1 gigahertz (GHz), up to about 300 gigahertz and wavelengths of about 30 centimeters (12 inches) by 1 mm (0.04 inches), according to the Encyclopedia Britannica. This region is further divided into a number of bands, with designations such as L, S, C, K,” Communications & radar Microwaves are primarily used for point-to-point communication systems to transmit all types of information, including voice, data, and video in both analog and digital formats, according to the Federal Communications Commission (FCC). They are also used for supervisory control and data acquisition (SCADA) for remote machines, switches, valves and signals. Another important application of microwaves is radar. The word “radar " was originally an acronym for Radio Detection And Ranging. Before World War II, British radio engineers discovered that radio waves of a short wavelength could be bounced off distant objects such as ships and aircraft, and the return signal could be detected with highly sensitive directional antennas so as to determine the presence and locations of those objects. The use of the term “radar” has become so common that it is now a word in and of itself, and can refer to systems that use microwaves or radio waves. A little-known historical fact is that an early radar installation was built atop Kahuku Point on the northernmost tip of Oahu., According to the Ha stato EB state website, The Station actually detected the first wave of Japanese aircraft en route to attack Pearl Harbor when the planes were 132 miles (212 kilometers) away. However, because the system had only been in operation for two weeks, it was considered unreliable and the warning was ignored. Over the course of the war, radar was improved and refined, and since then it has become an essential element of national defense and civilian air traffic control. Radar has found many other uses, some of which take advantage of the Doppler effect., An example of the Doppler effect can be demonstrated by an approaching ambulance: as it approaches, the sound of the siren seems to rise in tone, until it cries. Then, as she walks away into the distance, the siren seems to drop in tone. Robert Maanovic, a professor of physics at Missouri State University, said Doppler radar, which often employs microwaves, is used for air traffic control and vehicular speed limit enforcement., When an object approaches the antenna, the return microwaves are compressed and therefore have a shorter wavelength and a higher frequency. Conversely, return waves from aligning objects are elongated and have a longer wavelength and lower frequency. By measuring this frequency shift, it is possible to determine the speed of an object towards or away from the antenna. Common applications of this principle include simple motion detectors, radar guns for applying speed limits, radar altimeters, and weather radars that can monitor the 3D movement of water droplets in the atmosphere., These applications are called active detection, because microwaves are transmitted and reflected signals are received and analyzed. In passive detection, natural microwave sources are observed and analyzed. Many of these observations are conducted by satellites looking at the Earth or in space. Microwave heat sources One of the most common uses of microwaves is to quickly heat food. Microwave ovens are possible because microwaves can be used to transmit thermal energy. The discovery of this phenomenon was purely coincidental., In his book, " Everyone laughed...: From light bulbs to lasers: the fascinating stories behind the Great Inventions That Changed Our Lives” (HarperCollins, 1992), author Ira Flato racconta Spencer, an electronics genius and war hero, was visiting one of his Laboratories at the RA comp Spencer stopped in front of a magnetron, the feeding tube that drives a radar. Suddenly he noticed that a chocolate bar in his pocket had begun to Melt., "Further investigation led him to make the first batch of microwave popcorn as well as the first exploding egg. The first microwave ovens were quite large and expensive, but since then they have become so affordable that they are common in homes around the world. Microwave heating systems are also used in a number of industrial applications, including the processing of food, chemicals, and materials in both batch and continuous operations., This panoramic view of the chaantnantor plateau in Chile shows the antennas of the Atacama Large Millimeter / submillimeter Arra ( (Image credit: ESO / B. Tafreshi) Natural microwave sources Radio astronomers conduct observations in the microwave region, but due to the attention of the atmosphere, most of these studies are carried out using high-altitude balloons or satellites., however, perhaps the most famous observation of microwaves and terrestrials was conducted by two Bell Labs scientists working on a telecommunications system using a large horn antenna on the ground. According to the NASA Science website, “in 1965, using long L-band microwaves, Arno Penzias and Robertil The strange thing about the noise was that it came from every direction and didn't seem to vary in intensity much., If this statics came from something on our planet, like radio transmissions from a nearby airport control tower, it would only be from one direction, not everywhere. Bell Lab scientists soon realized they had discovered cosmic microwave background radiation. This radiation, which takes up the entire universe, is a clue to its beginning, known as the Big Bang.” Penzias and P The Cosmic Microwave Background Radiation was mapped with great precision by satellites., These observations revealed the tiny temperature variations that eventually evolved in the galactic clusters we see today. Analysis of this background radiation has also given astronomers clues to the composition of the universe, and scientists now think that about 95% of the cosmos is made up of matter and energy that cannot be “perceived” with conventional instruments, leading to the names of dark matter and dark energy. Future analysis of this background radiation could shed further light on what happened shortly after the birth of the universe — and, potentially, even before this universe existed, according to some cosmic models.
