Anonymous users2024-02-04Science refers to physics, chemistry, and biology.
1. Physics. Physics is the study of the most general laws of motion of matter and the basic structure of matter. As a leading discipline in the natural sciences, physics studies the most basic forms and laws of motion of all matter, from the universe to elementary particles, and thus becomes the research foundation of other natural science disciplines.
2. Chemistry. Chemistry is the basic natural science that studies the composition, structure, properties, transformation and application of matter at the atomic and molecular levels. It originates from life and production practices, and continues to evolve with the progress of human society.
Different from particle physics and nuclear physics, which study the smaller scales, chemistry studies the material structure of atoms, molecules, and ions, and the interaction between chemical bonds and intermolecular forces.
3. Biology. Biology, abbreviated as biology or life science, is a science that explores the laws of life phenomena and life activities, and is a basic discipline in natural science. The object of study is the structure, function, occurrence and development of living organisms, including plants, animals and microorganisms.
Its purpose is to elucidate and control the activities of life, to transform nature, and to serve practices such as agriculture, industry, and medicine.
Science
Science is physics, chemistry, biology and other disciplines, liberal arts is politics, history, geography and other subjects, high school liberal arts and science students have to study different subjects, in addition to the comprehensive examination of Chinese, mathematics and foreign language, in addition to the comprehensive examination of science, but also to test three subjects of language, science and mathematics, foreign language.

Anonymous users2024-02-03Science subjects include: Mathematics, Physics, Chemistry, Biology, Geography, Computer Software Applications, Technology and Design Practice, etc.
1.Mathematics
Mathematics can be divided into pure mathematics and applied mathematics. Pure mathematics mainly studies the structure and properties of mathematics itself, including algebra, geometry, number theory, etc.; Applied mathematics applies mathematical theories to practical problems, such as cybernetics, operations research, statistics, etc.
Mathematics is a universal means for humans to strictly describe the abstract structure and pattern of things, and all mathematical objects are inherently artificially defined. Hu Zi: In this sense, mathematics belongs to the formal sciences, and not to the natural sciences.
2.Physics
Physics is the study of the basic laws and nature of natural phenomena. It can be divided into two parts: classical physics and modern physics, of which classical physics includes mechanics, thermal, electromagnetism, optics, etc., while modern physics includes relativity, quantum mechanics, cosmology, etc.
Actual physical phenomena and laws are generally very complex and involve many factors. Discarding the secondary factors and grasping the main factors, so as to highlight the essential characteristics of objective things, is called building a physical model. The essence of physics is to establish a physical model for the research object, study the model through mathematical tools, and then explain and ** the research object.
3.Chemistry
Chemistry is the science that studies the composition, properties, structure and changes of matter. Chemistry can be divided into inorganic chemistry, organic chemistry, physical chemistry, and other specialized fields.
4.Astronomy
Astronomy is the study of the physics of celestial bodies and the morphology, structure, and motion of celestial bodies. It can be divided into specialized fields such as celestial mechanics, cosmophysics, astrochemistry, astrometry, etc.
5.Earth Sciences
Earth sciences are the sciences that study the physical, chemical, and biological characteristics of the earth and its various dimensions. It includes geophysics, geology, geochemistry, etc.
6.Life Sciences
Life science is the study of living organisms and their structure, function, development and evolution, including biology, biochemistry, ecology, genetics and other professional fields.
These are the main areas of science and are the curriculum for most of the high school years. There are many sub-disciplines and interdisciplinary disciplines in this field, such as statistical physics, biomedical engineering, environmental chemistry, etc.

Anonymous users2024-02-02Summary. Science departments generally refer to the natural sciences, applied sciences, and mathematical logic, as opposed to the liberal arts. The main subjects of science are:
Mathematics, Physics, Chemistry, Biology, Computer Software Applications, Technology and Design Practice, etc. The birth and development of science is the result of the development of human intelligence, which indicates that human beings truly understand how to think about nature, so the development of science is also the key to the development of human science and natural thinking.

Anonymous users2024-02-01What are the science subjects: mathematics, physics, chemistry, astronomy, earth science, biology and other science disciplines.
What is Science:
Inorganic chemistry is a hot topic in middle school, a periodic law, a large number of equations, and it is not required to memorize in college. Today's hot spots are only inorganic materials and catalysis. In secondary school, there is zero mastery of catalysis, while in college, catalysis is ubiquitous and can be explained with the above knowledge of physical chemistry.
After all, a chemical reaction is a reaction of electrons.
However, its limitations are also very large, in the research of synthetic methodology, the methyl deficiency of the raw material into ethyl may have a significant impact on the reaction results, this effect is not accurate with theory, the only research method is experimental verification. Therefore, organic chemistry is often jokingly referred to as an empirical discipline.
These things that can't be ** are easy to understand, like giving you an irregular rigid object, asking if you can pass through a hole, of course you have to try, to measure the calculation is strange.
The disadvantage of organic is toxicity, the toxic effect of organic matter is different from the corrosive nature of strong acids and alkalis that everyone is familiar with, and the toxicity is chronic, and I feel good for ten days and half a month or even for a long time, but after graduation, infertility may also be possible. Generally, you can't experiment without wearing two layers of gloves.
Analytical chemistry is the most widely used, and there is a tendency to become a separate discipline from chemistry (for example, polymers are separated from chemistry). In addition to the four major titrations, its main contents also include spectroscopy, mass spectrometry, chromatography, grade spectroscopy, nuclear magnetic resonance spectroscopy, etc., which is the basis of research in various related fields such as chemistry, and is the eye of researchers, without which we cannot understand microscopic molecules.
The spectrum originated in physics, and the intensity of sunlight under a prism is not uniformly distributed. From microwave to X-ray are all in the range of chemical research can be used, the microwave emitted by the microwave oven can just make the rotational energy level of the molecule jump, and the rotational vibration energy of the molecule is a component of internal energy.

Anonymous users2024-01-31Science departments refer to the formal sciences and natural sciences. The main science subjects are: Mathematics, Logic, Informatics, Computer Science, Systems Science, Physics, Chemistry, Biology, Earth Science, and Astronomical Spine Debate.
The birth and development of science is the result of the development of human intelligence, which indicates that human beings truly understand how to think and debate nature, so the development of science is also the key to the development of human science and natural thinking. The more well-known science universities in China include Peking University, Fudan University, Tsinghua University, Nanjing University, University of Science and Technology of China, Beijing Normal University, etc.
I think it's better for boys to take science. After all, boys have a lot of potential in science. >>>More
But to be honest, there is no need for this, and the direction that science students can choose in the college entrance examination is much greater than that of liberal arts students. >>>More
It depends on what school you are, if the school is good at liberal arts, choose essays, and the good memory is still essays. If you are good at science, you don't want to be tired.
I am a college student in the Department of Business English, I am in a similar situation to you, my Chinese scores in high school have always been among the top few in the year, when I first entered high school, I was also very worried about whether to study science or liberal arts, my father is engaged in education, so many teachers can help choose, and finally they gave me the choice of science, the reason is very simple, there are many science universities, and the chance of going to college will be greater than that of liberal arts, provided that you can study seriously! But I personally preferred the liberal arts at the beginning, but the geography of the liberal arts is very tricky, and the physics of science is very tricky, and finally I chose the science subject according to the arrangement, and it was okay at the beginning, and I could keep up, but after the second year of high school, the grades became more and more regressive, because I was not very interested in science and I felt that my brain was really not enough, and I didn't have the thinking of learning science at all, on the contrary, I have always been very confident in the liberal arts So I became the negative textbook of the science class, and the students in the science class relied on the liberal arts to score points! In fact, it's very embarrassing, if you don't understand physical chemistry, as long as the science comprehensive question is difficult, like the two of us, it will definitely be over, but if you have the confidence to learn well, of course, there is no absolute situation, but all the determination and efforts in me are in vain, because I was pulled by others about 50 points in the science comprehensive of the college entrance examination My average score in Chinese and English is 120, and the result is only 150 in science comprehensive, you can imagine it! >>>More
Machinery should be regarded as engineering, to the university major is divided into five aspects: arts, science, engineering, agriculture and medicine, arts and sciences for your current liberal arts can be, there is not much requirement, and engineering is like you said machinery, civil engineering, materials, these are a little difficult for liberal arts students, because for physics, chemistry requirements are relatively high, just like I studied civil engineering, there are three subjects are mechanics, fluid mechanics, structural mechanics, material mechanics, but it is not excluded that there are geniuses, you can leave science for several years can also learn very well, and like agriculture and medicine, for chemistry requirements, some medicine has requirements for physics, of course, if you want to apply for the examThere is no requirement now, but many colleges and universities recruit fewer liberal arts students for engineering majors.
