What is nuclear physics and what is the nucleus?

<> "The number in the figure represents the smallest unit of indivisible positive and negative electromagnetic information - qubits (qubits) by the famous physicist John. John Wheeler famously said, "It from bit."

After the development of quantum information research, this concept was sublimated to the point that everything originates from qubits) Note: Bits are bits.

In 1911, Ernest Rutherford discovered the nucleus while validating Thompson's model of plum pudding.

The atomic nucleus is the main component of the atom, located in the ** of the atom, accounting for about the mass of the atom, the density of the nucleus is extremely large, the nuclear density is about 10 14g cm3. The nucleus of an atom consists of uncharged neutrons and positively charged protons (each of the two types of baryon is composed of three quarks: red, blue, and green). When there are an equal amount of electrons around it than the protons in it, it constitutes an atom.

The nucleus is extremely small, for example, the atomic radius of uranium is 26634, and the proportion of the radius of the nucleus of hydrogen is 60250. But in this tiny nucleus, the mass of the atom is concentrated.

There are mesons in the nucleus that shuttle back and forth between protons and neutrons (transmitting strong nuclear force), neutrons will release -mesons become protons, and protons will release + mesons back into neutrons, and protons and neutrons in the nucleus will shuttle back and forth through mesons, and the transformation of each other is the mode of action of the strong nuclear force (see the figure below).

See the figure below: The middle sign in the above figure represents the smallest unit of indivisible positive and negative electromagnetic information - the qubit (qubit).

Famous physicist John. Wheeler John Wheeler famously said, "It from bit."

After the development of quantum information research, this concept was sublimated to the point that everything originates from qubits).

Note: Bits are bits.

The nucleus is an atomic-centered, positively charged particle. The weight of the atom is basically concentrated in the nucleus.

Physics is an interesting and useful subject that explores interesting topics such as the structure of time and space, the future of the universe, and the contribution to the sustainable development of humanity and the prosperity of the nation.

Just like the current research on controlled nuclear fusion, it is the contribution of nuclear physics to the complete solution of the energy problem of mankind. When the major studied is interesting and can promote the development of human society and science, it is probably the happiest thing on the way to study.

Today, we will talk about nuclear physics, which is a major that takes on a heavy responsibility.

What is Nuclear Physics? What do you study in nuclear physics?

Nuclear physics is a modern science and a branch of physics. Its main task is to study the radioactivity of substances. At present, the results of nuclear physics have been widely used in various fields such as medical diagnosis and treatment, production and life, and military.

Nuclear physics mainly uses cobalt-60, a radioactive element, to work, such as the military atomic bomb, hydrogen bomb, nuclear submarines, nuclear-powered aircraft carriers, etc. The major of nuclear physics requires learners to master the basic scientific knowledge and system of nuclear physics through the study of basic knowledge of nuclear physics, nuclear electronics, nuclear physics experimental methods, nuclear technology applications, etc., and be able to engage in basic and applied research in nuclear physics in industry, agriculture, national defense, medicine, environmental protection and related fields.

What is the future of nuclear physics majors?

Physics is the foundation of modern science and technology, which makes it a good choice for nuclear physics students to work or continue their studies. Graduates majoring in nuclear physics are mainly engaged in related work in nuclear power plants and other places, or engaged in applied research, scientific and technological development, and production technology management in factories and mines, enterprises and institutions related to nuclear physics and nuclear technology.

As nuclear physics is a cutting-edge modern science, graduates are mainly employed in large coastal cities, and can also choose to pursue postgraduate degrees in nuclear physics, nuclear technology applications and related disciplines.

Precautions for registration.

When applying for the examination, it should be noted that the nuclear physics major requires learners to have rigorous and meticulous observation ability and hands-on experiment ability, have a solid foundation in natural sciences, have a good foundation in humanities, arts and social sciences, and especially have a relatively solid foundation in mathematics. Learners should also have strong self-learning ability, innovation consciousness and high overall quality.

985 universities include Jilin University, Sichuan University, Harbin Institute of Technology, Beijing Aviation Difference Yintian University and Beijing Normal University. High-level universities include the University of South China.

The predecessor department of the School of Nuclear Science and Technology of the University of South China was founded in 1959 and is one of the earliest nuclear colleges in China, with a very strong professional strength in nuclear physics. There are also Shanghai University, Suzhou University and Beijing University of Technology, which are all good schools, and you can choose according to your own situation.

Rutherford speculated and calculated. The particle must have bounced back when it touched something positively charged in the atom, and the positively charged thing must have been heavy and solid, otherwise it wouldn't have deviated some particles from a large angle. It must be very small, much smaller than an atom, and it is not easy to be touched by particles, otherwise most of the particles will collide with this thing, and most of the particles will deviate from it at a very large angle.

Rutherford called this positively charged thing about the same mass as the whole atom but much smaller than the atom's size.
