Often quanta is not really necessary. But at the atomic level and in the atomic scale, they are very important. The dimensions of the atomic world contain an amazing property that must be changed by every measurement. When a person measures something, he cannot measure it without changing it.
R.For each dimension
Each scale requires three things. First, there must be a sample or a piece. It could be a single electron or a whole galaxy or earth. Then a power source is needed. That source can be light or heat or physical energy. One has to do something to connect with that sample, and you cannot interact with the sample without some sort of force in the process. The third thing a seeker does to make measurements.
People always do this when they go to the grocery store. For example, people go to the grocery store and want to buy some fruit, such as watermelon. And what do they do? They take the melon – that’s a sample. They are trying to determine his physical characteristics. Do you want to buy this watermelon? So you might smell the melon or click on it and listen to it.
They must apply force to the sample. And they have to have an investigator, who then determines the energy sample with the sample. And that gives them information about what they are trying to study. It happens all the time in people’s lives. It is also one of the most expensive laboratories in the world. Therefore, in principle, each measure is the same.

Measurement process on Subatomic Scale
For this measurement process, the smallest increase in energy that one can imagine is a photo, a single wavelength of light, a single piece of light hitting an atom. If an atom takes that photo and interacts with it, the atom must change in some way in the process. This situation is similar to trying to find a bowling alley in an empty dark room.
Somewhere in the empty dark room there is a bowling alley. And the only way to get that bowling ball is to take the second bowling ball and roll it into the room and listen to the claw. Once the bowling ball is found, a person does not know where it is after it is measured because the bowling process itself moves it.
Hesenberg’s Uncertainty Principle
The German physicist Werner Heinsburg, 1901-1976, described this problem — this quantum problem – in a beautiful mathematical form. Like Hysenberg, this expression is expressed in principle.
Werner eventually became director of the Max Planck Physics Institute in Munich. Hesenberg’s great insight was that one could not know exactly the exact location and speed of something in a sub-state at the same time.
In fact, he said, the instability of the position, sometimes the instability of the speed, must be due to the continuous mass distribution of Planck. And that can be described as a formula, [Uposition×Uvelocity>h/mass]. The instability in space, sometimes called delta position, must be the velocity or delta velocity, divided from Plank constant, h, by mass.

According to Hessenberg, rapid instability
According to Hiesenberg, if the mass is large, it is an indication of that fraction and there is less confidence in the location and speed. But if it is as small as an electron – the electron weighs only nine times 10-31 Kilograms – and if one wants to know the position of that electron, one would say that an electron is in an atom, and that the atom is only about 10.-10 Beyond.
Then those numbers are plugged into the fixture, and then the result is really different. Now, the place is fixed, so what is the lack of confidence in speed?
Well, Plank Fixed, 6.63 times 1034 joule-seconds, plugged in. Number of electrons, nine times 10-31 Kilograms pinned. And the distance – the electron in the atom is known to be 10-10 M.
And the result is 106 times the speed instability. Seven million meters per second is a huge distrust.

The relationship between position and speed on the Subatomic Scale
One can know its position or speed for any random accuracy, but post one – the better you know the place, the faster it will be. Or the more they learn about speed, the less they know about the place.
For something as big as a baseball, this is not a problem because it weighs so much that it washes away all other results. But for the electrons, it introduces the greatest instability in what is known about the sub-world.
Uncertainty means that the quantum world can never communicate in a critical way. Instead, take advantage of opportunities and use quantitative treatment for any quantum-scale event. This was to be used by Albert Einstein in deep-seated probabilities. That’s one of the reasons he doesn’t really like quantum mechanics.
Common questions about the importance of quantum on the quantum balance
There are three requirements for each measure, not just one as if subatomic scale But on every scale. The first criterion is sampling, the second is the source of energy, and the third is the need for investigation.
A Photo It is a small increase in power. It is a single wavelength and a piece of light that strikes an atom. When a single atom holds that small increase, it changes in the measurement process.
The great insight of German physicist Werner Hesenberg was that one cannot know the exact position and speed of an object. subatomic state Exactly at the same time. He expressed this dilemma in the form of mathematical uncertainty, like Hysenberg.
