20 10 after being single for three years, Peter Barkis, a mathematician who was still studying for a doctorate at Warwick University, wrote a paper about why I didn't have a girlfriend. Among them, he used a mathematical formula called Drake Equation to set up a series of questions such as "How many women live near me", "How many people are suitable for age", "How many people are single" and "How many people get along with me", and calculated that only 26 people in Britain are suitable for him. Moreover, he concluded that every night, he only had 1/285000 chance to meet one of them. Bacchus found a reason for being single for a long time, but at the same time he felt that it was almost impossible to find a qualified object. However, the good news is that Bacchus finally met one of them-Rose, a girl from London, and now he is married to her.
Mathematics is also applied to the prediction of marriage relationship. Psychologist John gotman and mathematician james murray developed a mathematical model to quantify the interaction and influence between husband and wife when they quarrel. Through visual image analysis, the emotional performance of husband and wife in the process of dialogue was scored, such as 4 points for approval, 2 points for interest and 2 points for refusing to communicate, so as to provide counseling for couples in marriage crisis.
They found that in the end, the score trend of each couple will gradually stabilize, and there will not be much difference. This trend represents a problem between husband and wife. If their conversation score curve keeps going down, it means that it is really difficult for them to appreciate each other, and marriage may not go on in the end. According to different functional images, guttman and Murray classified marriage into five categories: unstable, rational, avoidant, hostile and divisive. Although the first three have different modes of getting along, they all belong to a relatively long marriage. Through the tracking experiment of 130 couples 12 years, the overall prediction accuracy of this model is as high as 94%. Guttman and Murray later published this research in a book called Mathematics of Marriage: Dynamic Nonlinear Model.
If we say that linking love with mathematics used to be a high-end game for exclusive mathematicians, now with the gradual popularization of online dating, the role of mathematics in love is gradually strengthened. In the Japanese cartoon "A World Forbidden by Love", in order to solve the problem of declining birthrate, the Japanese government banned free love and took it over by the government. In other words, the government will help you decide the right marriage partner by analyzing a series of genetic genes and various data, and ensure the fit between them. Although this is an extreme assumption, more and more dating software is using a set of mathematical solutions to help users match potential suitable candidates.
