What's important for physics is to understand what natural phenomena he's studying. And how he described them in math, not blind back formulas. That's right, it's a problem that many of our students have in physics, so let's just start. Let's start by saying why so many of our students find it difficult. Have you ever heard anyone around you say why? Yeah, what i hear all the time is that physics is too hard, and it's all about formulas, and, um, they're all wrong, and the real problem with physics is that you don't know what he's working on, not too many formulas. Indeed, many people focus on formulas, ignoring the nature of physics. The language of physics is actually mathematical. To sum up the patterns behind the natural phenomena, and then use them to explain the other natural phenomena, so the core of it is three things, mathematical language. Natural phenomena, and the interpretation of patterns. Let's start with the first keyword. What is the role of mathematics in physics, and what are the common problems that students encounter when using mathematical tools? Math is actually the language of physics. Well, you don't think physics can be expressed without math, well, in physics it's not just adding or multiplying, but images. Function, scale, equation. Limits, geometry, extrapolation, and logical chains are all mathematical tools. Then, many of his classmates were making questions. Often because of these mathematical tools, um, and then he thinks he's not good at math, but most of it is because he doesn't know the physics. That's why he's got the wrong equation. Is there any way for students in the basics of mathematics to get them off the math in physics? In fact, there are only a few mathematical tools that are used in high school physics. You know, you've got all those key math tools, and that's all you need to know. Math is just an expression tool. Physical scenarios and physical relationships are at the core. Yes, you just have to get this logic straight. Even if your math isn't so good, you can do the physics right. Okay, then let's talk about this natural phenomenon, why the concept of physics can't be understood in stone and understood through natural phenomena. Because physics is a natural phenomenon, and if you're just going to go back to that definition of the formula. The more you learn, the more abstract you feel, the less you feel. Like when we're at school, power, power. If you go back to his definition, back to his formula. You'll find it very abstract and you don't know what to learn. Indeed, many classmates feel that these concepts are too abstract to remember at all. Yes, if it's a different angle, ask yourself, why would humans invent the word power field strength? Oh, because we need to describe how hard the same charge is in different places. When you figure out what he's going to solve, you look back at his definition and formula. The concept is actually a tool to explain the phenomenon. Well, it's not a dead end, you have to understand the phenomenon, then the concept, then the definitions and the formulas, so the physics is alive. We have just spoken about understanding the concept of physics through natural phenomena, and i would like to ask, what is the ultimate goal of physical learning? The science of physics is not about how many concepts you have, but about what you use. It's output, um, it's giving you a whole new subject. You can use the knowledge you've learned to analyze it and break it down and fix it. So the real test is your ability to migrate and apply knowledge. Yeah, a lot of physics seems to be changing. But it's all made up of some of the most basic models, and, um, you have to train yourself to be able to come from this complex subject. That's what you really need to learn. So, what are the underlying characteristics of physics, and how do they determine how we learn? The subject of physics has three important underlying characteristics. The first is that there are very few hard-backed things to die, and, well, even if the formula is a concept, it's a condition, but compared to biochemical history. It's really not a subject that can get high marks with a lot of recitation, so that's why physics is particularly easy to score. That is, people who can do it, people who can't do it, because it's more important that you understand and apply knowledge. Well, in terms of understanding and application, what exactly is that in physics? In physics, you have a special test of your ability to use knowledge, and, for example, he's not going to tell you which formula to use. He'll give you a sports scene or an experiment device or a map. A text description, and then let you judge for yourself what this is about, what is useful, what formulas are to be used, who is to be studied, and how many segments are to be divided. Oh, so physics can't say that i'm just a little bit of a problem, and you have to combine that knowledge into a network, especially in mechanics. It's all over high school physics, and, um, it's a powerful idea that's learned everywhere, whether it's electromagnetic or thermal or experimental. Does the logical connection between these steps seem to be particularly important? Yeah, that's the third characteristic of physics, and its logic is as tight as a chain. Oh, for example, it must be wrong to say that you've been misanalyzing the equation behind it, and then you must be wrong to use the wrong formula for the wrong motor energy. The relationships that you've been looking at wrong subjects must be completely confused. You don't say i'm just staring at formulas after you've carved all this into your head, and you know i'm going to have to understand what this is all about. Ok, we talked a lot today about how to really understand physics, and yes, it's just plain that we don't have to put our energies behind the equation. It is to understand how these concepts come about, how they relate to natural phenomena, and how we should really use them to solve new problems. All right, that's it. Thanks for listening. We'll see you soon. Bye-bye。", "ttts m"https://tosv. Byed. Org/obj/tos-tingtoutiao/ai podcast m== sync, corrected by elderman == @elder man
