Learn the tricks of solid state physics, how to teach yourself high school physics

Solid state physics is very abstract, because the object of his research is no longer a general system, but involves the structural energy problems between the atoms and molecules that make up objects, which is somewhat similar to atomic physics, but different. If you want to learn solid state physics well, there is no need to be entangled in difficult formulas and complex derivations, of course, if you are interested, these can help to understand, the key is to understand the concepts and research methods that are not in other branches of physics introduced in solid state physics, for example, at the beginning of the introduction of inverted lattice vector, the concept is very abstract, but its purpose is to study the crystal lattice, crystal properties, then you need to understand it from the perspective of crystal structure; To study the full band and the empty band, you need to connect the energy between the molecules to understand it. It is necessary to distinguish between micro and macro research methods, and do not study solid state physics with the same methods used to study physics.

I took this course several years ago, and I don't remember the specific content, I hope it will be helpful to you.

In a word: the main thing is to help focus on the understanding and application of concepts! There is no need to specialize in off-topic questions, the flexible use of the foundation is the top priority, which question is not evolved from the foundation?

Just do some so-called puzzles appropriately and summarize the principles of their propositions. Actually, solid state physics is not difficult because you don't believe you can learn it well! Basic perfection plus a good psychology must be valued.

Hope it helps.

Lay a good foundation, foundation is the key.

Here's how to teach yourself high school physics:

1. Consolidation of foundation; 2. Ways of thinking.

Cultivate; 3. Do more questions; 4. About the teacher.

Generally, the skills of explaining physics problems are not as good as those of mathematics, and there are not as many things to remember in physics as in chemistry classes, but there are more difficult to understand in physics than in these two courses, and it will be plausible if you can't figure out the connotation of physical concepts, physical laws, theorems and physical formulas.

Mastering basic physics knowledge is the primary task of high school physics review. The purpose of high school study is for the college entrance examination, and the questions for the college entrance examination are basically from the textbooks, and no matter how the questions are, they can't escape these textbooks.

Therefore, the consolidation of the foundation is to firmly remember the knowledge of the textbook. And if you don't grasp the definition well, you will often get things confused.

What about high school physics? What are some good ways to study?

Now there are many friends, all say that for high school physics is a relatively difficult subject, which makes physics a kind of sore in the hearts of many high school students, in fact, learning high school physics is also very simple, as long as you master good ideas, cultivate your own study habits, let yourself like this subject, in fact, it is relatively simple.

High School Physics Textbook.

1. Learn more, observe more, and think more.

In fact, high school physics is about some theorems of things in nature, these are many things around us that contain these truths, there is physics everywhere in life, for example, every time we take a car, we can see the outside world and the things outside these cars are going backwards, this is the reference in our high school physics, this knowledge point, there is knowledge everywhere in life, you have to experience it with your heart.

As long as we have an eye for discovery, you must look more at the many phenomena in your life, whether it is natural or life, you also have to look at the stars at night, see their changes, you will also find light and heat in physics and some law problems. This knowledge is still present in our lives.

1. Learn to start with theorems.

You have to attach great importance to some theorems and some dead concepts and some laws, but you not only have to remember this knowledge from time to time, you have to learn how to use it, this is the key, smart children are using these formulas and then applying them to their own mistakes, from which to find the problem, you also have to do from a small mistake, you can review a lot of knowledge, it is really a double harvest, which is also the key to whether students can open up in high school physics.

Second, change the incomprehension to be very proficient.

For learning, if you like this subject more, the better you will learn, maybe for various reasons to make you like this subject, maybe because of the teacher, some teachers grasp it tightly, you learn this subject very well, but some students just like this teacher and like this subject, if you change the teacher, you will not learn well, in fact, this is harmful to yourself.

High School Physics Exam Papers.

Read every textbook, read every unit, learn every problem, have key insights and solutions for every exercise in high school physics, maybe they use the same knowledge, as long as you remember a theorem you can do many similar problems.

How to learn high school physics well.

1. Read the textbook repeatedly. This step is crucial, and almost all top students have experienced it. Textbooks are the best teachers.

Many students will say, "The textbook is so simple, and the exam is so difficult, is it useful to see it?" "That's not right.

In fact, as far as I know, anyone who has a bad or mediocre score in physics is not a solid basic knowledge. They think they have learned well, but in fact they do not understand the most basic concepts and theorems. If you don't believe it, you can open the textbook table of contents and carefully review the relevant content section by section, and then you will understand what you don't understand.

For a physical concept, you have to understand it at a deep level. Let's say two small balls collide, what can you think of from that? What's wrong with momentum?

What's wrong with energy? You don't have to think about these questions when you have to do the questions. These questions may seem simple, but when you think about it, you can come up with a lot of questions. Moreover, such simple questions are the root of hundreds of millions of exam questions.

2. Do some simple questions. This second step, like the first step, is despised by many. They may think that doing those easy problems lowers their status, or that they are too busy with difficult problems to do the easy ones.

What is a "simple question"?It is those that directly examine basic definitions and theorems, such as exercises in textbooks and slightly more complex questions. The purpose of doing these questions is not to answer the right question, but to understand the question thoroughly and associate something from the simple question.

Some so-called puzzles are actually a combination of several simple problems.

3. Read more sample questions in reference books and do some general questions of medium difficulty. Personally, I like to read the example questions in the reference book the most, because the number of questions is small, and it is typical, and the answers are very standardized. After class, do a few medium topics to practice, the effect is often very good, do not ask for more, a few are enough.

It's still the same old saying, think back to it when you're done.

4. For difficult problems, take a look and do with an attitude of appreciation and playfulness. To be honest, there are no difficult questions in the current science and science exam, at most they are related to the reality of life. And the practical questions are often not too difficult, but the lack of reading the questions intimidates a group of people.

At least 70% of the questions in the comprehensive examination are easy or medium, so for most people, the focus is to lay a good foundation and do a good job in simple and medium questions; Besides, only when these questions are done well can we have the time and ability to do the so-called difficult problems. One more word of caution: the so-called medium difficulty questions are just simple questions that are slightly more complicated.

Rest assured, as long as you have a good book and a smart brain, you can learn everything on your own! If the time is relatively long, you can systematically improve your ability It is recommended to read Professor Cheng Jiafu's mechanics and electromagnetism, which are very good books, if you read 3 hours a day, and the math skills are good, it is no problem to save one, but if the time is not enough, or the math is not good, it is recommended to read the full solution bank, do more exercises, remember, there are many books, as long as you stare at a book to get it through, there will be results! Tell you a little experience, find the essence of everything!

It's not absolutely impossible to learn by yourself, it's just difficult, it's not about ability, it's just that there will always be blind spots in thinking, and many times it takes a little bit from others to suddenly wake up.

High school physics, long live understanding, deep experience.

There is also a physics competition that focuses on dynamics.

I think it's better to do it directly. The interpretation of the textbook is too detailed, although it is detailed, many of them are not tested, and it is too late to read them. The above list is basically the key point, and the effect will be seen faster.

It is difficult to learn physics by yourself, and it is difficult to have a teacher to teach it.

Racing is not an easy task, so don't take chances. Now self-study to lay a good foundation, the topic must be done. Self-study textbooks are the main thing, so you should look at the past one by one, don't look at the flowers, and there is also to summarize the previous knowledge of finding rules and contacting them.

Elective 3-1 Chapter 1 Links Celestial Knowledge in Compulsory 2, and 3-5 Chapter 1 Connects with the Laws of Kinematics.

You can find some good questions on the Internet to do.

"Three Points and One Test" is good, you can buy it and use it. If you really don't understand, you can discuss it with your classmates and teachers, and I'm all of them. It's not under ninety-five. Physics is about studying and thinking.

Circuit diagram analysis is easy to do.

Label all nodes with abcd....Then mark the two points with wires connected with the same letter, that is, the equipotential point, and then draw the circuit diagram again.

In physics, there are basic physics and theoretical physics (experimental physics is separated).Solid state physics is a theoretical physics content. Involved.

The microstructure of the body, to learn it well:

You must be a physics student, have two or three years of experience studying physics in college, and understand that analytical understanding is the basis for learning physics.

Method. Atoms are well both.

Have a strong mathematical foundation and be able to use it flexibly.

There is a person named Huang Kun, you want to study "Solid State Physics", you should know or have heard of this name. He is the founder of "Solid State Physics" in my country, an old-timer. In the early 60s of the last century, I studied his book "Solid State Physics" at the Institute of Physics of the Academy of Sciences.

Now there may be a new version, go to the library to find it. Books on Solid State Physics by other young scientists should also be available in the library. Reading more of their books will help you learn Solid State Physics well.

Here are some ideas for you on how to review:

1. Chapter review, no matter which discipline is divided into large chapters and small class hours, generally when all the lessons of a chapter are finished, the whole chapter will be strung together in the system to talk about it again, as a review, we can also do this, because since it is a chapter of knowledge, all the class hours must be related before, so we can find out what they have in common, and use the association memory method to string these fragmented knowledge through the line, which is more convenient for us to remember.

2. Error correction and sorting: It is inevitable to make mistakes in the process of doing questions, whether you are careless or not, you must habitually collect these wrong questions, and each subject has a set of mistakes, when we review before the exam, they are the key review objects, so since you missed once, you may not be wrong the second time, only in this way you will not lose points again on the same problem.

3. Mind map review: Mind map is a great invention, which can systematize, diagram and visualize the information in your brain in memory, and can also help you analyze problems and plan as a whole. Drawing knowledge with a mind map to organize and memorize it can quickly analyze the context and focus of knowledge, and remember it firmly.

Learning physics is very process-oriented, a process of cognition, understanding, and application. 1.Cognitive:

Use the things or phenomena around you, or even some examples narrated by the teacher, to help yourself fully understand it and become interested in it. 2.Understand:

Memorize formulas, theorems, experiments, etc. in an understandable way. It can be understood and memorized in clever ways such as visual thinking. For example, what is a vacuum can be understood in this way:

The vacuum is really empty, there is nothing left. 3.Application:

One is to prepare for exams, and the other is to explain some physical phenomena around you. So, when studying, first of all, don't be afraid, because your previous experience of not learning well may suggest something to you, which may lead to a vicious cycle for you. Try to tell yourself, "I can do it!!

In fact, psychological suggestion is very useful! However, in order to increase your confidence, it is best to do a good job of pre-study and be aware of it. Secondly, you should follow the teacher's train of thought in class, take some notes appropriately, and write down some knowledge points that are not clearly stated in the book or even omitted and are easy to make mistakes.

Take time out of class to practice more, don't prevaricate for any reason, thus giving up the best time to practice, which can only lead to tragedy in the end. Last but not least, you must make sure to make a timely summary. For example, the paper of the last exam has been sent down, and although it has been carefully corrected, you still have to think about why it was wrong.

How is the correct answer calculated? Will it be wrong if I get it again next time? Wait a minute.

I think that through these study methods, I will definitely be able to learn physics well. I hope it will be helpful to you and I wish you progress in your studies.
