Mathematics, physics and chemistry are mathematics, physics and chemistry, which are generally called natural science. Corresponding to this is social science, including Chinese, history, politics, English (and other language subjects).

Question 2: What does mathematics mean? Short for mathematics, physics and chemistry.

Question 3: What are the abbreviations for mathematics and physics? _? Mathematics, physics, chemistry. Science corresponds to physics and chemistry students, that is, physical chemistry biology.

Question 4: Is it really useful to learn mathematics and physics well? In fact, for many people, his own knowledge is not important. His role in education is to cultivate a person's rational thinking ability. If you can deeply understand some mathematical and physical problems, then your thinking ability and reasoning ability can also be improved to some extent. In fact, this is the foundation of education. Teaching people how to think and pursue scores is simply putting the cart before the horse.

Question 5: What are the skills in math and physics? Learning skills and methods should be paid attention to in order to achieve better learning results and improve learning efficiency, especially in learning Chinese. Here are some ways to learn Chinese, which I hope will help you: 1. Abbreviations. The so-called abbreviation is to compress the amount of information in memory as much as possible, and at the same time basically remember what to remember. Remember that the main point is not to give up other content, but to understand other content, which can greatly increase the amount of information in memory and improve learning efficiency. This is how liberal arts writing works. Second, comparative learning method. Contrastive learning helps to distinguish confusing concepts and principles and deepen the understanding of knowledge. It requires us to classify knowledge according to different characteristics and then compare it with memory. For example: rights and obligations in political textbooks; Metaphor and metonymy in Chinese textbooks: parallelism and verticality in mathematics textbooks; Combination and decomposition in chemistry textbooks: Comparative learning method can be used not only for learning within the same discipline, but also for interdisciplinary comparison. For example, Chinese sentence analysis can be used to analyze political concepts and so on. Reading with questions helps to concentrate and clarify the purpose. It requires us to read the thinking questions after the text before reading, and think while reading; At the same time, we are also required to look for questions in preview, so that we can concentrate on listening when the teacher explains the questions in class; Finally, try to solve the problems one by one in practice. Don't be intimidated by the problem. The process of solving problems is the process of your progress. Fourth, the fast reading method. Speed reading method is not only used in Chinese reading, but also has important application value in browsing mathematics learning textbooks. The key points of fast reading are: (1) get rid of "argot" and browse quickly with your eyes to get information; (2) broaden your horizons and let your eyes get more information; ⑶ Grasp the teaching materials as a whole and get important information; (4) In the fast reading training, attention, observation and memory can be improved, so that the mind is agile, the brain is flexible, and the learners become smarter and smarter. Five, to achieve "three grasping" 1, grasping attitude: requires concentration and care in learning, courage to overcome difficulties in learning, accurate, neat and clean writing, and not "anticlimactic" and "dragon and phoenix dance". 2. Grasping skills: ask questions, do homework, be accurate, be fast, and have quality quickly; Language expression should be clear and vivid, manual operation, and oral recitation should be skilled. 3, grasp ability: mainly observation, attention, memory, imagination and thinking, in all after-school learning should pay attention to seriously cultivate the above abilities. Here are some suggestions on how to learn math well. First, improving class efficiency is the key. During the study period, the efficiency of class determines the learning effect. We should pay attention to the following aspects to improve the efficiency of attending classes: 1. Preview before class can improve the pertinence of lectures. The problems found in the preview are the focus of the class; You can make up the old knowledge that you haven't mastered well in the preview, which will reduce the difficulties in the process of attending classes and help improve your thinking ability; Preview can also cultivate your self-study ability. 2. Pay attention. Concentration is to devote yourself to classroom learning, from ear to ear, from eye to heart, from mouth to hand. Ear listening: it means listening attentively, listening to how the teacher lectures, how to analyze and how to summarize. Eye-catching: while listening to the lecture, read textbooks and blackboard books, and watch the teacher demonstrate the expressions, gestures and actions of the experiment. Heart orientation: that is, think with your heart and keep consistent with the teacher's teaching ideas. Mouth-to-mouth: refers to taking the initiative to answer questions or participate in discussions. Reaching out: I write down the main points of the lecture and my feelings on the basis of listening, watching, thinking and speaking. 3, take notes, notes are not records, but a simple and clear record of the main points in the above lectures for review. Second, review in time. Review is not to read books or notes over and over again, but to do a retrospective review: first recall what the teacher said in class, then open the notes and books and compare the contents that were not clearly recorded, so as to consolidate the contents of the day, and at the same time check the effect of listening on the same day, and also put forward necessary improvement measures for improving listening methods and improving listening effect. Third, finish your homework carefully. Many students pin their hopes of improving their math scores on doing a lot of problems, which is inappropriate. The important thing is not to do more questions, but to do them well and efficiently. We need to do some exercises on the basis of accurately mastering the basic knowledge and methods. In addition, we should pay attention to the efficiency of doing the problem, that is, how much we have gained after doing it. This requires some "reflection" after doing the problem, thinking about the basic knowledge used in this problem, what is the mathematical thinking method, and whether there are other solutions to this problem. > & gt

Question 6: Why do you say that you are not afraid to learn math and physics well and travel around the world? What about other subjects? What does this sentence mean? This sentence is a bit exaggerated, but it is also true in English. It is called STEM. So this sentence refers to real skills, science and technology, engineering mathematics, easy to find a job, promising, and so on. In addition, China's culture is official-oriented, so many people can't learn mathematics and physics, or their elders won't let an only child do it, so they have to learn liberal arts to be an official.
