THE ORIGIN OF THE DISCOVERY ELECTRICITY HISTORY
A small incident if the "man" who lived for a time that is immeasurably long in the earth knows nothing about electricity. They try to explain to him the phenomenon of thunderstorms by imagining that some god or super-nature creature creates wind because of anger, or a fight in the sky. Thunderstorms terrify our primitive ancestors. They should thank him because the lightning gave the first fire, and therefore opened the way to civilization. An interesting question of how different lives on earth will develop if we have an organ that can sense electricity.
We can not blame the ancient Greeks for failing to know that the force that caused the lightning storm was the same as the one they saw if they rubbed an amber. The stone will attract straw, feathers, and other light objects. Thales of Miletos, a Greek philosopher who lived 600 years before Christ, was the first to observe this phenomenon. The Greek word for amber is an electron, and so Thales calls this strange style "electric". For some time this style is considered to have the same essence with the magnetic force of iron stone because the effect of attraction seems to be the same. And indeed in reality there are many connections between electricity and magnetism.
Perhaps the Israelites knew something about electricity. This theory is based on the fact that the Temple in Jerusalem has metal rods on its roof which certainly acts as a lightning rod. In fact, for 200 years since its foundation, the temple has never been struck by lightning, even though Palestine is a thunderstorm.
There is no other evidence that electricity was used in ancient times, except that ancient Greek women adorned the spinning wheels with amber trunks. Once the woolen threads are rubbed by amber, they first pull it and then reject it. An intriguing little spectacle that eliminates the tiredness of spinning.
Over the past 2,000 years since the discovery of Thales, no research works have been done in this field. Dr. William Gilbert, originally a doctor of Queen Elizabeth I, made the ball spin. He experimented with amber and rocks. And he finds an important difference between electrical and magnetic attraction forces for objects that have amber-like properties, such as glass, sulfur, wax. He gave the name "electrica" and the symptoms he called "electricity".
In his famous work "De magnete" published in 1600, he gives an assessment of his work. Although some sources say he was the creator of the first electric machine, but this machine is essentially the invention of Ottovon Guericke, mayor of Magdeburg and the creator of the air pump. This last machine demonstrated immensely in front of the emperor and a number of important men at Ratiabon Bavaria in 1654. He showed that two powerful horses consisted of eight unsuccessful tails, respectively, of two spherical spheres in which Disampered with the engine.
Von Guericke's electric machine consists of a large disk that spins between brushes. This round causes a fire jump between the two metal balls. This machine became a very popular toy among the elite society. More than nothing. In 1700, an Englishman named Francis Hawksbee made the first electric light. He emptied a glass ball with a vacuum pump and turned it at a very high speed while rubbing it with his hands until a weak beam of light was emitted.
A more advanced creation is the electrical cooler, now called the "Leyden bottle," created by Dutch scholar Pieter van Musschenbroek of Leiden. A bottle filled with water, the inside and outside are coated with a metal layer. Thus, the two layers are separated by a bottle wall from a non-electric conductor glass. A metal rod with a stump at the end is immersed in water, with a bump on the water. If it is electrically loaded, it can be enough to store it, so that if someone offends the bulb, it will feel a strong electric shock.
Benjamin Franklin, born in Boston, Massachusetts, is the fifteenth child of a poor English soap maker. He was more than 30 years old when he started studying natural phenomena. And when he was past 40, he accepted a theory that had been laid down in the foundations by a professor from Leipzig, J.H. Winkler. The theory states that the discharge of electric engine, lightning, and flash is essentially the same thing.
