Positive and negative particles of matter
In 1920, a force was defined that holds the atoms composed of positive and neutral particles together. It could not be a normal electrical charge. It must be a different form of charge. So, so-called " Color strength. It was only 50 years later that a strong interaction was demonstrated. 1934 discovered Enrico Fermi the so-called weak interaction that is responsible for radioactive decay. When radioactive elements break down, high energy electrons or their positive antiparticles - positrons - are created. So we have four interacting forces: a strong one that holds particles in atoms together, normal, weak, weak-radioactive decay, and gravitational force. It is assumed that the first three forces arose during the Big Bang explosion. Assumed! Then they emerged as the force of one, when apart from the collapse of the expanding universe they separated themselves. This is THEORY. To confirm this theory, scientists are trying to prove the correctness of gigantic accelerators, such as the LHC in Geneva. Length 27 km, costs 3 billion EUR. The conditions that prevailed during the VT are, in fact, the scientists are approaching slowly. In order to simulate the VT and to create the forces of interaction, we would need a 1000 light-years accelerator. It's not a crap, it's math. Let us return to electrons and electricity.
Electric current can not be seen, yet from the end of 19. century developed the electricity industry using. Still, no one could imagine this PROUD. To be with "By" (!) has the definition that the electric current consists of small particles that are positively charged which simply move from the PLUS pole to the MINUS pole of the electrical source, eg the battery. It was only many years later that 1897 found that the discovered electron is charged negatively and ranges from MINUS to PLUS! It has been proven to be the construction of television screens, the original giants. Is not that amazing? On virtually completely wrong definition were and are built power plants and developed smart phones!
How can it be that such tiny particles, which can not be seen and which have a massive weight, can illuminate a million city, heat houses and power huge engines? The answer is in their quantity. In one cubic centimeter of copper wire, for example, there are unimaginable 6 × 10²³ atoms. 6 x 10 and 23 to zero. That's more than the number of stars in the visible universe! For an idea: Take a pile of cube sugar. What area would that take? You certainly will not! One square meter is 100 x 100 cm. This is 10.000 cubes. For one square kilometer - 1000 x 1000m, you need 10 billion balls, ie 10¹⁰. That's a good number. But: Europe from Portugal to Ural and from Nordkap to Sicily has an area of 10 million square km. But we have "only" 10¹7 sugars. The total surface area of our planet is 500 million square kilometers. We get the number of cubes 5 x 10¹⁸. To cover the entire surface of the Sun, which has 12.000x larger than the Earth, we get close. The number of sugar cubes reaches 6 x 10². That means we can pave the surface of the sun 10x by sugar! And please, in one cubic centimeter of copper wire. So it's an incredible amount of small particles that work here.
Electricity is measured in electrical engineering. current in amperes. Taking a simple pocket flashlight, that is, a flashlight, in its bulb from the minus pole to the pole plus, approximately 1015 electrons per second flow. Converted to sugar - we would cover half the Czech Republic. In a second!
