Xue Zhilu has heard that if we use mathematical equations to express life, every small equation in the process of life has a certain solution, but the general equation of life is an uncertain result, or an unstable solution.
Mathematics is a wonderful subject. Some mathematicians say that the world is the expression of numbers. Now the foundation of science is also mathematics. Computers and the Internet, which are widely used in life, let alone technology based on mathematics.
Xue Zhilu thinks it is possible to express life, calculate life and predict life in a mathematical way.
In ancient times, Qimen Dunjia and Zhouyi Bagua were used to calculate the trajectory of life through some specific data of life.
It involves profound nouns. Xue Zhilu can't understand them, which may have magical effects, but it may be difficult to get started.
Xue Zhilu has received more than ten years of continuous education in modern mathematics. He thinks mathematics is OK (elementary mathematics, advanced mathematics, Xue Zhilu is confused), so he tries to analyze life with mathematics.
In junior high school, Xue Zhilu came into contact with the equation. The unknowns are usually one or two, and there are few unknowns when there are three. From the first unary linear equation, to the unary quadratic equation, to the binary linear equation, to the binary quadratic equation, it is almost the same. The multivariate multiple equation only exists in Xue Zhilu's imagination.
Solving equations is the process of obtaining unknown results through existing known conditions. Junior high school students can solve both univariate equation and binary equation.
It may be rare to put the equation into real life.
In fact, it is not so complicated. The simple equation of life can be set up as follows: for example, six athletes are known to participate in the 400 meter race, and the athletes' performance at ordinary times is also known. The athletes' competitive state has not changed particularly during the race. A rough solution is to use the daily data of athletes to predict the results of the game.
If you want to predict the rise and fall of the stock, or even the range of rise and fall, you need to know the following known numbers: what is the subject matter of the stock; Who is the shareholder of the stock? Has there been any change recently? What is the reason for the change; How about the performance and authenticity of the stock; Whether the social environment is beneficial or harmful to the stock; Whether there is any abnormality in the flow of funds, whether there is any new technology, and how much impact it has on the industry involved in this stock, etc.
If we want to predict whether two young men and women can become husband and wife, we need to know: their personalities, preferences, what they accept and what they resist; What is the family background, the personality of parents, siblings and relatives, and the economic foundation; Whether the outlook on life, world outlook and values are the same; What are their weaknesses, whether they can be determined by others, under what circumstances they will be affected, what kind of social environment is, how much impact they will have on their judgment, whether there will be emergencies to determine the judgment, and so on.
If you want to judge (predict) a person's life, you may need to consider too many unknowns: the place of birth (planet, country, region), the era, era, scientific and technological (or other civilizations) living standards, parents' education, health, personality, hobbies, family rise and fall, local customs, Whether there are individuals who are good at influencing others in the population who may be contacted after birth, whether there are any irremovable influences on the spirit, physiology, psychology, etc., whether there are physical injuries or even losses, whether the general environment will change suddenly, whether the influencing factors are stable, etc.
In ancient times, some people could predict a person's life direction through the eight characters of his birthday, which was really powerful. Of course, it is also possible that many data do not need to be collected from objects. Local astronomy, geography, humanities, etc. can be collected at any time by themselves. When adding computing, there is no need to specifically collect data from objects.
Previously, in the legend (there are many stories about deities), an expert could figure out the good or bad luck of a person, know the danger he was about to face, and also give a way to eliminate the danger.
In Xue Zhilu's opinion, it is not impossible to predict a person's life trajectory because of the high position of a master, sufficient data collected, and a set of sophisticated algorithms.
As for the way to eliminate the danger of life, it is a matter of perspective. Just like people in the three-dimensional world, it is easy to judge the direction and existence of creatures in the two-dimensional world.
It seems simple, but in fact it is extremely complicated. There are few people who can understand and calculate, so it is so respected.
Speaking of this, Xue Zhilu couldn't help thinking of his major, medicine.
Even with the development of science and technology and the progress of medicine, there are still many unclear points about the understanding of the body. The judgment of a patient's disease requires a lot of physical and chemical tests, so that it can be judged at a certain time, and then the corresponding treatment can be given.
Even drugs with definite effects, such as antibiotics and antihypertensive drugs, may have obvious effects for most people, but for a small number of people, the effects may not be good, and even adverse drug reactions, drug allergy, shock and even death may occur.
This shows that the human body is a rather complex system, and the understanding of science and technology on the human body is not particularly comprehensive at present, and the individual differences of each person will also be obvious.
What causes obvious individual differences? Genes? Environmental Science? psychology? Spirit? Race? All these need scientific, careful and patient research.
Xue Zhilu knew that human body has great potential. For example, there is sometimes too much difference in strength between people who lack exercise and those who exercise scientifically. From the weight bearing data (for example, weight lifting), it is good for ordinary people to lift 50 or 60 kilograms. Weightlifters can lift hundreds of kilograms of weights. A petite girl who lacks sports may not even be able to lift 10 kilograms.
Physically, how much weight can be carried depends mainly on the number and thickness of muscles. The number of muscle fibers in general people should be the same, and the difference is mainly in the fiber thickness. The thicker the fiber, the stronger the load capacity.
Xue Zhilu sometimes thinks that the muscles of the arms and legs are affected by exercise, so the heart is also a muscle organ. Can you also change the load capacity of the heart through exercise? Because the heart load capacity of many elderly people decreases, they can't bear their own body, and they can't bear it when they move their heart a little, which will lead to chest tightness and cardiac insufficiency. Although medicine can alleviate symptoms, it is only an auxiliary function, which can make the aging heart stronger again, or make the heart less vulnerable to aging, and people's happiness index and quality of life will improve a lot.
