Introduction
Electronic (english: electron) is a subatomic particle with negative power, usually marked as
I don't know. Electronics belong to the light subcategory and interact with other particles by gravity, electromagnetic force and weak nuclear power. Koko is one of the basic particles that make up the substance and cannot be broken down into smaller particles。
Electronics carry a 1/2 spin, which is a fermy. Therefore, no two electrons can be in the same state, based on the principle of compatibility of bubbles。
The inverse particles of the electron are positive electrons (also known as positives), all of which have the same mass, spin, and charge size as the electron, but the positive and negative properties of the electron. Electronics and positives will collide with each other, generating more than one pair of photons in the process。
Historical trace
Why does friction turn on electricity? How does a frictioned object attract a light object? More than 300 years ago, some scientists thought that electricity was an invisible magic liquid. They imagine that there is an invisible invisible fluid in objects that can be powered by friction, and when they are wiped, this invisible fluid flows quietly out of the frictioned object and attracts something small and near。
This view now appears to be ridiculous even for primary school students, but in the midst of electrology, it is believed by many to be true, even by newton, the leading scientist of the seventeenth century, that there is a special flow of liquid in electrical objects。
In the eighteenth century, the theory of electricity as a mythical “electricity” was raised. And just like all the "neutron" theories of the wind, people put everything together as a "neutron" role. - thermal heat of the object is due to the accumulation of “heats” within the object; the elasticity of the object is due to the presence of “flexin”; the incendiary properties of the object are due to the fact that it contains “flammants”; the magnetic properties shown by magnets or magnets are due to the so-called “magnetics” ... It follows, of course, that the charge of the object should be caused by “electrons”。
But what exactly are these things called "neutrons"? No one knows, because neither the early formulations of “heats”, “burns” nor the emergence of “electronics” have ever been seen and touched, but more importantly, they have never been detected or confirmed by experiments。
Thus, these “nutal” opinions are more a pretext for avoiding the problem and for ignorance of things than a theory of interpretation。
By 1733, a french man named doo fe had observed several experiments in which he believed that there were two kinds of heterosexual electricity — negative (negative) and positive (positive) — that attracted each other, while the opposite type of electricity showed a repulsion. And that's what we all know about heterosexuals and homosexuals。
More than a decade has passed. By the 1940s, franklin had further proposed the reason why objects would carry positive or negative electricity. In his view, this was due to the distribution of electric power between charged objects. He also presented the “particle doctrine” of electricity, that is, all electricity is made up of countless tiny charged particles called “charges” by the franklin tube. This can be described as the first ladder of modern electronics, where franklin has drawn a vague outline of electronics。
Up to the beginning of the nineteenth century, a number of scientists made clear the concept of electronics. They believe that there is a tiny particle electron in the object, and that currents are caused by the flow of electronics. This correct view is even closer to modern electronic theory。
For thousands of years, human beings have struggled to move forward on the path of exploring the nature of electricity and finding its source. At the beginning of the nineteenth century, a rough electronic concept was finally first introduced, marking a major breakthrough in electrical research. This electricity gap, which has already been opened, could logically be used to reach the electronic world, thereby accelerating the establishment of modern electronic theory. But there is a huge barrier at the threshold of electronics. The liquid concept of electricity at that time was deeply embedded in the minds of many, especially since the liquid doctrine of electricity included great scholars like newton, who replaced science and prejudice rejected truth. The correct electronic concepts and doctrines of electricity have been met with widespread opposition and rhetoric, and early electronics have failed to resonate, even in the scientific community。
It would seem that when the liquid doctrine of electricity governed the scientific community at that time with everything at king's landing, it was not possible to break through the requirements of old theory and free electricity completely from liquid theory without producing solid evidence and living experimental results。
So people try to prove the existence of electronics with experiments。
Starting in the late 1930s, it was discovered that currents could be passed not only through metal conductors or lines, but also from thin gases. This is what we call thin gas discharge。
According to the liquid doctrine of electricity, which is an invisible liquid, based on many of the thin gas discharges observed, is it possible to say that liquid electricity can overfly the thin air without restraint
In 1879, british scientist cruz did an interesting experiment based on the former human experiment, the famous cruz experiment。
When a glass tube with a higher vacuum is bound by a metal electrode at both ends (figure 2-1), when near-thinvolved pressure is applied between the two electrodes (one end with a negative voltage is called the cathode; the electrodes connected to the positive voltage is called the anode), a flashing light of the same size as the cathode is present on the glass wall of the cathode, as if a strange ray had been fired from the cathode. This ray pen is directed at the tube wall opposite the cathode, which gives light to the tube wall. People call it cathode rays。
Figure 2-1
In order to verify the existence of cathode rays and to detect their nature, people placed a "+" font in front of the cathode in the glass tube (figures 2-2) to see if anything really came out of the cathode and hit it on the wall. It is true that when clouds are added, there is a very clear "+" dark shape on the glass. That is why one dares to assert that there is indeed a ray coming from the cathode and that the rays are going as straight as the light。
Figure 2-2
Many see cathode rays as an invisible light (light waves), as is the case with infrared or wood that is invisible to human eyes; however, it is also suggested that cathode rays are electric particles (electronic currents) and other observations are made。
There's a lot of talk, and no one can convince them. The debate was marathon and lasted about 20 years. This protracted debate was quelled by the famous thomson experiment. The result of the dispute - the discovery of electronics。
1897, tomson, british scientist (note: joseph john thomson, joseph in the title). In order to detect cathode rays and confirm the presence of electrons, an electric field and a magnetic field (figures 2-3) have been installed on both sides of cruz ' experimental glass tubes. At this point, it was discovered that the light from the original tube wall had shifted. This indicates that cathode rays have been bent by the electric or magnetic field。
Figure 2-3
Tomson's experiments negate the popular notion that cathode rays are light (light waves), as many have repeatedly shown that light does not bend, either in the electric field or in the magnetic field. Only electric currents bend in electric or magnetic fields. There is no doubt, therefore, that cathode rays are an electric ray。
Tomson quickly determined that cathode rays were negative, based on the reverse direction of the cathode rays in different electric and magnetic fields, and that such negative rays were composed of particles with negative electricity; he further measured the speed of the negative particles and the ratio of the amount of power carried by each particle to its mass. Thomson was surprised to discover that, regardless of the metal material used as a cathode, particles from the cathode were always carrying the same power and mass ratio. Thus, such negative particles are constantly and objectively present, and the phenomenon of currents is due to the movement of such particles. Thomson refers to such negative particles as “electronic”。
By 1911, united states physicists, mirigan et al., had measured the amount of electricity carried by individual electronics and the quality of individual electronics using precise experimental methods. Strangely, no matter how different the cathode material is used, every electron emitted from the cathode has exactly the same amount of electricity and the same mass, which is more progressive to show that electron is a constant particle with a fully defined mass and constant amount of electricity。
What is even more surprising is that all electrical objects are found to carry more electricity than electronics, and they always have several integers of electricity. This tells people that electronics have the smallest amount of electricity, and electronics are the smallest “electric” particles, just as atoms are the smallest particles of matter (thus they were called “atoms” when electrons were used)。
Since all electron-enabled objects carry electron-enabled electrons integrities, there is reason to believe that the object is electron-enabled。
A century and a half ago, the electric pioneer franklin introduced the charge concept. He imagines electricity as a particle of electricity, and now the prophecy of the pioneers confirms that franklin's ideas are blooming in the new science park. After generations of forward and follow-up efforts, old assumptions have finally become a scientific reality, and ghost-like electricity has finally been discovered and seized, the first time mankind has discovered the existence of basic particles。
