The Medical Explanation of the Principle of Love

Airplane flight was mainly based on the following principles: 1. ** Creating lift ** - For an ordinary airplane, the shape of the wings was designed to cause the air to flow at different speeds across the upper and lower surfaces of the wings. According to the Bernoullian principle, the greater the flow rate of the fluid, the lower the pressure. The upper surface of the wing was usually curved, so the air flow was fast and the pressure was small. The lower surface was flat, so the air flow was slow and the pressure was strong, thus creating an upward pressure difference, which was the lift force. In addition, the lift was also related to factors such as the angle of attack (the angle between the wing chord and the relative airflow speed). - For helicopters, the large propellers stirred the air to generate lift when they rotated. When the lift was greater than the helicopter's own weight, the helicopter could take off, and the height could be adjusted by changing the speed of the propeller in flight. 2. ** Obtained Thrust Force ** - The aircraft could obtain forward thrust through the engine. A common type of engine, such as a piston-type engine (such as the early star engine), produced forward traction by driving the propeller to rotate. The turbine jet engine was a high-speed air compression engine. The air was compressed by the high-speed operation of the air intake. The combustion chamber sprayed oil and burned it. The gas rushed back to the turbine, which drove the air compression engine. The gas flow was ejected from the spout to generate thrust. Turbofan engines (turbine-fan engines) had two internal and external bypass passages. The ratio of the air flow rate of the external bypass passage to the internal bypass passage was the bypass ratio. The larger the bypass ratio, the more fuel efficient it was. It was widely used in aircraft flying at subsonic speeds such as passenger planes. Its main thrust could come from the air ejected backward at high speed from the external bypass passage. The turbine prop-jet engine was similar to the turbine jet engine, which was connected to a decelerator and drove an external propeller. It was mostly used in small or low-speed subsonic aircraft, but there were exceptions. There was also a propfan engine. There was no decelerator, and the propeller had a high speed. The fuel efficiency was further improved, but it was noisy. Turboshaft engines transmit power through a shaft and are used in helicopters. 3. ** Controlling the flying posture ** - The aircraft had three axes of motion: pitch, roll, and yawing. The roll was controlled by the ailerons, the pitch was controlled by the elevators, and the yawing was controlled by the rudders. - If the helicopter only had the main propeller rotating, the body would rotate according to the conservation of momentum. Therefore, the small propeller on the side of the tail of the helicopter was used to prevent the body from rotating, so that the helicopter could turn left, turn right, or maintain a stable course. 4. ** Maintain center of gravity and balance **: The position of the aircraft's center of gravity needs to be reasonably distributed to ensure balance and stability during flight. Different types of aircraft structures and arrangements were designed with the center of gravity and balance in mind. The novel "Hundred Years of Spaceship" is equally exciting.

The scientific principle of love involved both physiological and psychological aspects. From a physiological point of view, when people meet a potential partner, the brain will release chemicals such as Dopamine, Adrenaline, and Serotonin. These substances can stimulate people to produce excitement, pleasure, and happiness, resulting in a feeling of "heartbeat." For example, during puberty or in an environment where young people gathered, the secretion of hormones was more exuberant, which was one of the physiological foundations of love. From a psychological perspective, love was a complex psychological phenomenon. First of all, people seek recognition, understanding, and support in love. They satisfy their needs for a sense of belonging, security, and social connection by establishing deep emotional connections with others. Secondly, different love situations had different psychological factors. For example, the reason for a relationship was that two people were attracted to each other because of their common interests, personality traits, etc.; The reason for a perfect match was that one party was attracted by the other party's personality charm (talent) and image temperament (appearance); The reason for love was that after a long time, they had a full understanding of the other party; The reason for a good relationship was that they had similar worldviews, life views, values, money views, and preferences, so it was easy to have a good impression of each other. In addition, people would also fall in love because of the same level of soul consciousness, even if there was a huge difference in ability, social status, family background, strength, and so on.

From a scientific point of view, there were several main reasons for heartache in love. First, psychological level 1. ** Ideals, self-projection and gap ** - When people were in love, they often saw each other as their "ideal self." When the gap between a person's " real self " and " ideal self " was greater, it was easier to develop infatuated love. If there was a problem in the relationship, such as being rejected or finding out that the other party was not what one expected, this huge gap between ideal and reality would lead to psychological pain, because it meant that the ideal image one pursued could not be achieved in reality. 2. ** Emotional dependence and loss ** - In the process of love, both parties gradually established an emotional dependence relationship. When this relationship was threatened or broken, there would be a sense of loss. It was like being used to some kind of emotional support or companionship. Once it was lost, the brain would regard it as the loss of an important resource, which would trigger a negative emotional reaction, which would be expressed as heartache. 3. ** The mutual influence of emotions ** - In the stage of passionate love, the emotions of both parties were more interconnected. When the other party's behavior or attitude changes and is no longer as self-centered as in the early stages of love, there will be an emotional gap. For example, if the other party turned from being concerned to being indifferent, this change would cause one's emotions to turn from positive to negative, feeling neglected and unloved, which would lead to heartache. Second, the physiological level 1. ** Hormonal changes ** - In love, the human body secretes a variety of hormones, such as Dopamine and Oxotocinin. Dopamine could bring pleasure, and it was the source of excitement and passion in love. When a relationship is in crisis, such as a breakup, the secretion of Dopamine may decrease sharply. This sudden change in hormone levels will affect the brain's reward system, causing discomfort similar to withdrawal reactions, resulting in heartache. It is related to intimate relationships and emotional bonds. When a relationship breaks down, the change in the level of the hormone will also have a negative impact on the mood. 2. ** Brain activity area ** - Some areas of the brain are closely related to emotional experience, such as the almond. When faced with stress and sadness in love, the almond nucleus would be activated, triggering the body's stress response, including physiological reactions such as accelerated heartbeat and rapid breathing. These reactions were accompanied by psychological heartache. At the same time, the brain's prefrontal lobe and other regions were also involved in the regulation of emotions. When the negative events in a relationship exceeded the regulation ability of the prefrontal lobe, one would feel an uncontrollable heartache.

Here are some basic principles related to love: 1. ** Love triangle theory **: American psychologist Sternberg proposed that love is composed of passion, intimacy, and commitment. The initial passion would gradually turn into mutual responsibility in the development of the relationship. 2. [Babe's Law: This is a social psychological effect. In love, the better one person treats another, the less the other person may cherish it.] Because after experiencing a strong stimulation, the stimulation given would become insignificant. 3. Broken window effect: If you encounter a conflict in a relationship that is not resolved, it will be like a house with a few broken windows that are not repaired. It will induce the conflict to escalate. 4. ** Romeo and Juliet Effect **: When external forces interfere with the relationship between the two parties, the relationship between the two parties will be strengthened and the relationship will be stronger. 5. [Veblen Effect: In a relationship, it can be understood as making yourself more valuable and popular. Creating a sense of crisis for the other party will make the other party cherish you more.] 6. [The more you look at something, the more you like it. When you are in a relationship, you will often appear in the other party's field of vision. After being familiar with the other party, the chances of the other party liking you will increase.] 7. The Hedgehog Law: Love requires a "psychological distance" to give the other party free space. Otherwise, both parties may hurt each other. 8. Murphy's Law: The more afraid you are of losing a relationship, the tighter you hold on to it, the more likely you are to lose it. 9. ** Principle of utility **: From an economic point of view, utility refers to the satisfaction or pleasure that an individual obtains from a lover (which can be regarded as a special kind of goods and services). It is an indicator of an individual's overall happiness. When the person in love had a high utility value to oneself, it was easy to start a relationship, but the utility would decrease. For example, in a long-distance relationship, the woman's utility value to the man would decrease after repeated times, and she might be attracted to a third party with a higher utility value. 10. ** Principle of Reciprocity **: This is the basic rule of interpersonal relationships. In a relationship, when one party pays for the other party, the other party will be willing to repay the other party with similar actions. If this principle is broken one-sidedly, if one party always pays and the other party never returns or one party always pays and does not give the other party a chance to return, it will cause damage to the relationship. 11. ** Principle of mutual respect **: It includes respecting the other party and respecting oneself. Respect for the other party was easier to understand, while respect for oneself required not to be overly submissive and pander to the other party in a relationship. One had to be brave enough to express their own opinions and opinions, and both parties had equal status. 12. The principle of mutual trust: Trust is very important in a relationship. It involves loyalty, finances, promises, character, and many other aspects. 13. ** Shadow personality effect **: The psychology master, Carl Junge, proposed that people have a dominant personality and a shadow personality. People will be attracted to people with their own shadow personality traits. For example, a man's suppressed sensitivity becomes a shadow personality, and he may be attracted to a sensitive woman, and vice versa.

Love was a sentimental term. It was a unique emotion that a person held towards things and people. It was a large and abstract concept. Love, on the other hand, usually only referred to the feelings between a man and a woman, and the scope was smaller. We can come to this conclusion.

Love poems usually contained deep emotional expressions and meanings, and they often needed a certain amount of explanation to understand. The following is an explanation of a love poem: You are the most beautiful scenery in my life. You are the most beautiful scenery in my life Like a bolt of lightning streaking across the night sky Illuminating my dark world It brought light and hope. Your eyes are like two stars Shining with a deep light Your smile is like sunshine It warms my heart. Your gentleness is like the spring breeze and drizzle Nourishing my exhausted soul Your love is like a hot summer day It makes me feel cool and comfortable. You are the most beautiful scenery in my life Let me feel the beauty of love I'm willing to do anything for you I'll accompany you through every moment of your life. There are countless sceneries in this world But only you are the most beautiful scenery in my life I want to be with you Walking through this wonderful time Forever.
