The editor of the People's Education Edition High School Physics Elective 3-1 said:The charge of all charged bodies is either equal to e, or equal to an integer multiple of e.
The editors unilaterally mistakenly believedThe charge of all charged bodies is either equal to e, or equal to an integer multiple of e.
In order to counteract the editor's mischaracterization, we need to understand an experiment, which is the famous oil drop experiment.
The oil droplet experiment was first measured in 1909 in a physics experiment conducted by Robert Andrew Milligan and his student Harvey Fleischild in the Ryerson Physics Laboratory at the University of Chicago in the United StatesThe amount of charge of an electron。Robert Milligan was awarded the Nobel Prize in Physics in 1923. The purpose of this experiment is to measure the charge of a single electron.
Through the historical study of the amount of electric charge, we find that e here is the charge of the electron, not all the charged bodies as the editor said.
The discovery of quarks:
In 1949, Fermi and Yang Zhenning proposedFermi Young model, but it doesn't explain exotic particles very well. Next, the Japanese physicist Shoichi Sakata proposedComposite model of hadrons。However, willSakata modelIt has been applied to the study of the baryon family in hadrons, but the results have not been very satisfactory.
In 1964, American physicists Murray Gell-Mann and George Zweig independently proposed a quark model of hadrons. In this model, the hadron of neutrons and protons is made up of more basic units, quarks. They have a fractional charge of +2 3e or -1 3e times the basic charge and a spin of 1 2e
From here we can clearly see how wrong everything is here.
Of course, not all editors will make random edits. As shown in Fig.
Thinking: There are obvious mistakes in the textbook about the concepts of basic physics, so we must dare to question the views of the textbook in the process of learning physics.
Newton said, "The reason why I see farther than others is because I stand on the shoulders of giants." ”。
We should learn from the basic theories of those giants in order to overturn the current erroneous view of physics.
