Chapter 105 Surface Tension
When I was in school, I didn't learn about surface tension, but I learned it by watching videos on a regular basis. Surface tension is both familiar and unfamiliar to me. In TV dramas and variety shows, they are often heard saying that someone has tension. In fact, whether it is the tension of words, plot, drama, or even more abstract artistic tension. They are all literary tensions in nature, and they are characterized by a strong degree of subjectivity. Physical tension is much more objective. So, is the ideological inspiration of literary tension derived from physical tension? I think so. Didn't we mention generalization, and that's another example. In literature, there is a discipline of linguistics. It has been said that dance is the mother of arts. And I say that language is the mother of literature. Without language, there is none. And dance is what people decide after thinking. In literature, there is probably no other discipline that can compare with language. First, not only are there many types of languages, but the content of each language is also quite complex. Whether it's a TV drama or a dance, practice and theory need to be written in words. Some ethnic groups have a language, but no written language. As a result, many important historical events and empirical achievements cannot be preserved. There is a saying that those who can read words never need to learn to speak, but those who can speak need to understand words. A bit off topic. Regardless of the discipline, its foundation must be language. And the deepening of language is the written word. The human mind could not be preserved before the written word. When words appeared, writing became a problem. Paper appeared very late. China only had paper in the Song Dynasty, and bamboo was used before. When printing and papermaking were introduced to Europe, Europe prospered. It's like a lot of praise books, but very few people praise the talk. Being able to keep them is one of the great advantages of books, and the relative professionalism of books adds to their value. In fact, the reason is that the literary tension of words is greater than that of spoken words.
People often boast that they can speak many languages, but I want to say how much you know about it. Take our Chinese, there are countless idioms. The ancient texts are full of sweat, and the poems are as many as cows' hair. And there are countless academic books. While most people prefer to talk, I love words. Just like when we speak, what we actually say is also physical. Previously, it was not easy for books to survive. But now it's different. I plan to compile our discussions into a book, and I'll post them on the relevant platforms. As long as the platform is still there, our work will still be there.
Napoleon said that a soldier who does not want to be a marshal is not a good soldier. However, I don't think Napoleon would have felt that it was good for him to be in one area alone. Napoleon is known to be a military strategist. The greatest success of his life was to win numerous battles, but he was also a math enthusiast. The famous Napoleonic triangle was proposed by him, and the theoretical level is quite high. At the same time, he personally revised the Napoleonic Code. And this code has also become the source of the basic law of Western countries.
Okay, so let's start with the physical tension description. Mizukawa seems to have been forced by some kind of force during this time, causing the opening to be longer and longer.
According to the encyclopedia, tension is a type of tension formed by an object subjected to a tensile force. Although not every force has a corresponding particle, for example, the graviton corresponding to gravity has not yet been discovered. However, most of them have a counterpart. Tension, as a force of an object, is present on the surface of an object. The question is, how is it not on the inside? The encyclopedia also says that the rope has tension, so it becomes a lot more concrete. We know that surface tension is physical and does not involve chemical changes. Then, particles below the atom can be excluded. Now there are only atoms and molecules, so which one is it? The tension is superficial, then it should not be the atoms inside the object. Then, it can only be said that it is a molecule. However, none of the physicists claim that the particle corresponding to the tension is a molecule. If this is obvious, then why haven't they noticed? This question can only be verified by experimental physicists in the future.
In the "Acoustic Basics" co-authored by Du Zhu and others, it is said that the deformation and reduction of the string are related to its tension. Then I can't help but wonder if the tension of the strings is the greatest in the deformed part, or is it all the tension that converges in the deformed part? When I think of tension, I think of elasticity. Isn't drawing a bow and shooting an arrow a typical example of using elastic force, and the same is true for slingshots. So, what is the relationship between elasticity and tension? I think that tension is actually a kind of elastic force, and the reason is that the force exerting the greatest force is the largest at the point where the deformation is greatest. And it transmits the force to the other parts. There are ancient Kongrong pears, and I will selflessly hand over my time to you today. Duenias unwittingly followed in the footsteps of Mizukawa Rice, and it was a bit long.
We know that friction and tension are on the surface of an object. It's like tension and buoyancy. We know that force is the manifestation of energy, so they should have a corresponding form of energy. I think friction corresponds to kinetic energy, while tension corresponds to potential energy. And they are both a type of internal energy. Friction can be analogous to vibration, while pulling can be analogous to collision. They differ in the number and duration of exposure. It should be said that pulling is a linear form of friction. In other words, the trajectory of friction is a broken line, and the pull is a straight line. It can be said that pulling is a simplification of friction. Friction and tension have nothing to do with it, but friction and tension are related.
Since tension is a force, and force is usually directional. For example, the direction of gravity is vertically downward, while the direction of magnetic force is related to magnetic inductance lines. We know that tension is generated by pulling, and pulling naturally has different pulling methods. If the tension has no direction, how can it be adapted to different ways of pulling? So I think it's directional. Liuzi Fenglai also began to change.,No longer directly say the conclusion as before.。。
Liuzi Fenglai just said that tension has a direction, which is of course. Pulling is divided into horizontal pulling and vertical pulling, and tension naturally has two types: horizontal and vertical. And different tensions have different causes. The horizontal is produced by the mass of motion, and the vertical is produced by gravity. It is inaccurate to say that tension corresponds to potential energy. If it is a horizontal tension force, then it corresponds to kinetic energy instead of potential energy. However, the vertical tension corresponds to the gravitational potential energy. Since the essence of tension is the embodiment of energy, and energy and velocity are related. In general, the faster the speed, the higher the energy. Since tension is the embodiment of energy, then nature is related to energy. I think the tension changes with speed. We think that solid tension and liquid tension are the same thing, but they are not. Fluid tension has a role to play in describing capillaries. In fact, there is a lot more to the knowledge of tension, and what we know is only the tip of the iceberg. Sometimes, we shouldn't always work behind closed doors, but rather ask more learned people for advice. Do you think that's so? Margarita's ending was somewhat unexpected.
After hearing this, the three of them felt that it made sense, so they went to consult a solid mechanician and a fluid mechanician together. Then, I consulted many well-known physicists.
