When a certain macroscopic physical quantity of the system under study.
When a measurement is taken, the actual value measured each time inevitably shows a statistical average relative to it.
This phenomenon is called "fluctuation". There are many examples of fluctuations, such as Brownian motion.
is a case in point. Brownian motion is an important experimental basis for molecular motion theory, and the study of Brownian motion plays an important role in the establishment of fluctuation theory. For example, the critical opalescence phenomenon in the liquid and the scattering phenomenon of light in the air are caused by the fluctuation of the medium density.
The phenomenon of current fluctuations due to the thermal motion of charged particles can also be observed in various circuits. For example, when measuring a weak current with a galvanometer, this measurement cannot be performed if the current to be measured is less than the fluctuating current, or if the deflection of the galvanometer coil caused by the current to be measured is less than the Brownian motion of the coil itself. Fluctuation is a statistical average behavior of a large number of microscopic particles, which is the result of the irregular thermal motion of a large number of microscopic particles such as molecules, atoms, electrons, etc.
The relative value of fluctuations is usually small, but in some phenomena it can still be observed and can have a significant impact.

The actual measure that can be measured at each moment has a more or less deviation from the mean value, and these deviations are called fluctuations (fluctuations). Fluctuations are accidental, disorganized, and random.
Heisenberg's uncertainty principle represents the relationship between position fluctuations and momentum fluctuations.
x p h/4π
The Einstein-Heisenberg uncertainty relationship indicates the relationship between the fluctuation of time and the fluctuation of energy.
t e h/4π
The standard deviation here indicates fluctuations.
Vacuum quantum fluctuation is the relationship after the uncertainty is expressed by the generation and annihilation operators, in which the vacuum energy fluctuation is greater than the energy required to produce the positive and negative white holes of the people's particles, i.e., e h 4.
As a result, the vacuum produces a white hole of positive and negative particles.
The positive and negative particles generated by the new quantum fluctuations in the white hole horizon of the Zhengwang Minmin Particle move to the first and third regions respectively under the action of the opposite direction of Schwarzschild time and the opposite direction of the light cone in the Cruzkar coordinate system, forming a positive and negative universe. The white hole of the anti-Wang anti-Wang particle finally entered the third area to form a dark positive and negative universe.
According to the Hawking black hole radiation formula, the radiation power of the white hole of the people is created by the Hawking black hole, and the energy of 19 suns is created per second, after a very long time, but it is a finite long time, and finally in our universe, after the elementary particles reach a certain density, the elementary particles combine into nucleons (protons and neutrons), atoms, molecules, and finally evolve into various planets, stars, black holes, galaxies and other cosmic celestial bodies, and evolve life in some stars. The anti-universe is undergoing a similar process of cosmic evolution. The positive and negative universes cannot be annihilated by each other due to the isolation of the light cone.
According to Heisenberg's uncertainty principle, a single pendulum cannot stay at the lowest equilibrium point, and it always keeps rising and falling (deviating) at the lowest point.
According to Heisenberg's uncertainty principle, the upright stick is always rising and falling (oscillating), deviating from the equilibrium position to a certain extent, and finally falling to one side, which is also called spontaneous breakage (asymmetry from a symmetrical state to one side).
The ball at the top of the Mexican cap does not hold at the very top, and according to Heisenberg's uncertainty principle, it will keep moving away from the very top and eventually roll down into the groove on the edge.
The vacuum is not empty, it is the ground state of the generation and annihilation operators of various particles, but the ground state is always constantly excited, and these generation and annihilation operators always deviate from the ground state, so that the vacuum constantly produces positive and negative particles, but they are quickly annihilated. Annihilation is followed by continuous creation, and so on, and so on.
When the vacuum quantum fluctuation reaches a certain degree by chance, it will produce a white hole of positive and negative particles, which cannot be annihilated because they are mutually exclusive, becoming the first pair of physical particles in a vacuum, and finally the positive and negative universe will be created by the white hole of positive and negative particles.

Summary. Fluctuation is a commonly used term in physics to describe the deviation between the measured physical quantity value and its theoretical value, which can be further subdivided into two cases: rise and fall, the rise means that the measured value is higher than the theoretical value, and the fall means that the measured value is lower than the theoretical value.
What does it mean to go up and down in physics? Please give an example to explain. Why does the fluctuation phenomenon occur, and what is the difference between fluctuation and error? Is it an error between fluctuations and pre-shipments? Letter quietly.
Fluctuation is a commonly used term in physics to describe the deviation between the measured physical value and its theoretical value, which can be further subdivided into two cases: rise and fall, the rise and fall indicates that the measured value is higher than the theoretical value, and the crack quietly indicates that the measured value is lower than the theoretical value.
For example, if a physicist measures the weight of a peach, if the weight of the measured mountain is higher than the theoretical value, it means "rising", and if the measured weight is lower than the theoretical value, it means "falling". Fluctuations may be caused by the error of the measuring instrument, the error of numerical calculation, the change of the measurement environment, etc., and the error may be in the false hole in the sensitivity difference, the measurement range is not accurate, etc.
The fluctuation and error are not completely consistent, and the error may cause the fluctuation phenomenon, but there is also the fluctuation phenomenon caused by non-error reasons, so the fluctuation and the error are not exactly the same.
Teacher, I still don't quite understand what causes the fluctuation phenomenon to occur.
You can understand it this way.
The cause of the fluctuation phenomenon is caused by the gravitational force generated by the Moon and the Earth.
Due to the continuous movement of the earth and the moon, the relative positions of the earth, the moon and the sun are changing periodically, so the tidal force of the fibrillation is also changing periodically, which makes the tidal destruction of the mu file occur periodically.

Ups and downs refer to the tide or the price of goods. For example, food ** fluctuates according to the law of supply and demand.

Magnetic saturation is a physical property of a ferromagnetic material. When the strength of the external magnetic field slowly increases, the magnetic flux density (which you can understand as magnetism) inside the ferromagnetic material also slowly increases. When the magnetic field strength reaches a certain level and is strengthened, the magnetic flux density of ferromagnetic materials increases more and more slowly. >>>More
Definition of the phenomenon of supercooling:
During crystallization, the actual crystallization temperature is lower than the theoretical crystallization temperature. At a certain pressure, when the temperature of the liquid is lower than the freezing point of the liquid at that pressure, the phenomenon that the liquid still does not solidify is called supercooled phenomena of liquid. The liquid at this point is called supercooled liquid, which is a thermodynamic condition. >>>More
The density of snow is very small, but the damage caused by avalanches can still crush people, mainly because avalanches contain more ice than soft snow. Under the hardness and gravity of the ice cube, it will cause a great deal of damage to the human body. Of course, in addition to this reason, there are other objective reasons, and we must carefully learn some basic common sense, so that we can protect ourselves in the event of a disaster. >>>More
