The Art of Deception and Adrian's Tale Chapter 11

There is a kind of even force in mechanics, which is also worth studying. Wang Anshi of the Song Dynasty was a reformist and rejected the old party, while Sima Guang was conservative and rejected the new party. The two parties advocated opposite views, but their forces were equal. From the perspective of mechanics: "Two lines of force are parallel, equal in strength, and opposite in direction, which is an even force." The endless rotation of the millstone is a manifestation of this force. Since the reign of Emperor Shenzong of the Song Dynasty, the old and new parties have taken power and fought for decades. The political situation of the Song Dynasty was like a millstone, rotating endlessly, which led to the invasion of the Jin people and the disaster of the southward migration. After the Xinhai Revolution in my country, the various parties and factions were unable to resist each other, and their forces were not enough to defeat each other, which became an even force. The political situation also rotated like a millstone, and Japan took advantage of it to enter.

All events in the world are caused by the contact between people. We can assume that a person, an "I", is a mathematical binary, a Y and an X. According to analytic geometry, we can get five lines: (1) two straight lines; (2) a circle; (3) a parabola; (4) an ellipse; (5) a hyperbola. Human affairs are ever-changing, but they are always connected with people, so they cannot escape these five tracks. The examples given in the previous chapter all belong to two straight lines. The two figures in Chapter 2, A and B, and Figure 3 in Chapter 3 belong to circles. In addition, there are three types of parabolas, ellipses, and hyperbolas, which are described as follows:

What is a parabola? When we throw a stone outward, it is a centrifugal force. Gravity attracts the stone, which is a centripetal force. The centrifugal force of the stone cannot break through gravity, and it finally falls. The path of the stone is a parabola. The path taken by a weak nation towards the great powers is a parabola. For example, the Korean people wanted independence, which created a centrifugal force for Japan, and Japan used force to subdue them. They could not break through Japan's sphere of influence, just like a thrown stone that could not break through gravity and finally fell to the ground.

If we throw a stone, assuming there is no ground to block it, it will go around the center of the earth and return to my original position, and it will keep spinning, just like the earth orbiting the sun. This kind of path is called an ellipse, which is a combination of centrifugal force and centripetal force. Mathematically speaking, the distance from a point to two fixed points is equal in sum. The trajectory of this point is called an ellipse. The equal sum means the equal value. When buying and selling, the customer hands over money and the shopkeeper hands over goods. The two are equal in value and can be regarded as one object. This is the customer throwing out an object, bypassing the shopkeeper and returning to his original position. From the shopkeeper's point of view, it is also throwing out an object, bypassing the customer and returning to his original position, forming an ellipse. Both buyers and sellers are satisfied. The customer has money and must buy from a certain store. This is centrifugal force, but the goods in his store are enough to attract customers and have gravitational force. The shopkeeper has goods and must sell them to a certain customer. This is centrifugal force, but the money in his pocket is enough to attract the shopkeeper and has gravitational force. Due to the combination of gravity and centrifugal force, the customer pays money and the shopkeeper sells goods. Everyone gets what they want and the transaction is completed. This is an elliptical state.

Another example is free marriage. A woman does not have to marry a man, but the man's love is enough to attract her. A man does not have to marry a woman, but the woman's love is enough to attract him. The gravitational force and the separation force, maintaining their balance, are also in an elliptical state.
