Anonymous users2024-02-09Physics is the natural science that studies the structure of matter, the interaction of matter, and the laws of motion. It is an experiment-based natural science, and one of the eternal themes of physics is the search for orders, symmetry, and symmetry-breaking10, conservation laws, or invariancePhysics is a regular summary of people's knowledge of the transformation of matter in inanimate nature.
There should be two kinds of such movements and transformations. The first is the extension of sensory vision by early people, and the second is the results obtained by modern people through the invention and creation of scientific instruments for observation and measurement. Physics can be divided into two parts: micro and macroscopic, macroscopic is not to analyze the effect of a single particle group and directly consider the overall effect, which has appeared in the earliest days, and the theory of microphysics has gradually improved with the development of science and technology.
Chemistry is the science that studies the composition, structure, properties, and changes of matter. The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world.

Anonymous users2024-02-08Physics is the science of the basic structure of matter and the basic laws of motion (mostly the study of life and nature) Chemistry is the study of the structure and properties of all things and the use of matter.

Analysis: Chemical physics is the science that studies physical problems in the field of chemistry, and is a marginal discipline at the intersection of chemistry and physics. Chemical physics was born shortly after the advent of quantum mechanics.
The founding of this discipline was marked by the founding of the Journal of Chemical Physics in the United States in 1933. After the birth of chemical physics, it developed very rapidly, and one of the important masterpieces is "Introduction to Chemical Physics" published by Slater in the United States in 1939.
The main research contents of chemical physics include: (1) atomic and molecular wave function theory; (2) atomic and molecular spectroscopy; (3) chemical kinetics and collision process; (4) the whole field of liquid structure; (5) polymers; (6) Statistical mechanics of equilibrium and transport theory; (7) performance of molecular crystals or other types of hail crystals; (8) constitutive thermodynamic properties of various states of matter; (9) the use of laser to study physical properties; (10) The working mechanism of the laser, etc.
The junior college only needs a graduation certificate, and the undergraduate must take the degree certificate, and the undergraduate is more difficult and the learning is richer!
Resignation is the termination of the labor contract through negotiation between the two parties. Because the contract period has not expired, the employer generally submits an application for termination of the contract, and after the employer agrees, it is deemed to have negotiated the termination of the labor contract, and the employer shall pay the labor remuneration and other rights and interests due to the employer. Self-resignation means that the employer unilaterally terminates the labor contract without consulting with the employer, which not only does not get the labor remuneration it deserves, but also may be sued by the employer for breach of contract losses. >>>More

In fact, I think it's just a step away, but it's also a long way away It's easy to like someone, but it's hard to love someone. Like someone, I hope he can look at you all the time; Love someone, hope you can always watch him Like someone, hope he can be good to you; Love someone and hope that he will accept your kindness to him Like someone and hope that he will be there for you when you need him; To love someone and to want to be there for him when he needs ... To like someone is not necessarily to love him; But the premise of loving someone is that you must like him. >>>More
When you like someone, you want to be with him because he will bring you joy; After leaving, you will miss, laugh at the thought of it, and then move on with your peaceful life and look forward to seeing him again. When you love someone and you want to be with him, it is a kind of reluctance to worry about him, afraid that he will be wronged, afraid that he will not be able to take good care of himself; After leaving. You'll miss too, thinking about it and sighing"I wonder how he's doing now? >>>More
