Computer fortune telling _ computer fortune telling is surprisingly accurate

Is computer fortune telling really credible?

Mr. Liu found that Xiaoyun, the daughter of the second day of junior high school, was addicted to fortune telling. She doesn't read books every night, hides in her room, writes all her classmates' names on a piece of paper, and then writes down information such as constellation, zodiac, blood type and so on. See which boy and which girl are "more suitable".

Only when Mr. Liu asked did he know that this was what his daughter learned from a constellation prediction website. The daughter told her father that this kind of "computer fortune telling" is very popular among their classmates now. Words such as "constellation" and "blood type" are often talked about by colleagues. Even some students will say such "amazing words": "I didn't do well in the final exam because I didn't have luck studying that day." "I am a Taurus, and I will find a Virgo man as my husband in the future, so my marriage will be very happy." A survey report on junior and senior high school students in Beijing shows that 100 middle school students, only 1 people think that burning incense is effective; However, 40 out of 100 middle school students believe that "the constellation determines fate".

This is also a superstitious idea. Is it really possible to decide people's fate through "innovation" in the form of astrology and divination, and then package it with high-tech computers? Is computer fortune telling really that fascinating? In fact, this is just a computer game at best. We can easily use the pigeon hole principle in mathematics to illustrate its absurdity.

Pigeon hole principle, also known as pigeon cage principle or Dirichlet principle, is a special method to prove the existence in mathematics. For the simplest example, if you put three apples in two drawers in any way, there must be two or more apples in one drawer. This is because if there is at most one apple in each drawer, there are at most two apples in two drawers. Using the same reasoning, we can get:

Principle 1 If more than n objects are put into n drawers, at least one drawer has more than two objects.

Principle 2 If more than mn objects are put into n drawers, at least one drawer has m+ 1 or more objects.

Now let's go back to computer fortune telling. Suppose we calculate a person's life span as 70 years old, then there are 70×2×365=5 1 100 different combinations of sex. We take these 5 1 100 specific fates as the total number of drawers, so we take this 1 1 000 billion population as the number of objects put in drawers, because1.1×109 = Although their gender, origin, qualifications and status are completely different, they must have the same "fate" stored in the computer in advance. This is the scientific principle of computer fortune telling.

In ancient China, people knew how to use the pigeon hole principle to expose the fallacy of birth. For example, in Qing Dynasty, Chen Qiyuan wrote in Notes on Leisure Zhai: "I don't believe in the theory of pushing the steps by the stars, thinking that a person lives once (meaning one hour, that is, two hours), and in terms of age, there are 4,320 people. Counting on Jiazi (referring to 60 years), there are only 259,200 people. Today, it is only a big county, and it has reached the number of its accounts. During this period, when the princes were born, there must be people born at the same time. What is the difference between the rich and the poor? " Here, a year is calculated as 360 days, and one day is divided into 12 hours, and the number of drawers obtained is 60×360× 12=259200.

Therefore, the so-called "computer fortune-telling" is nothing more than storing the manually compiled fortune-telling sentences in their respective cabinets in advance like Chinese medicine cabinets. Who wants to tell fortune is to mechanically take out the so-called fate sentence from the computer cabinet according to the different combinations of birth date and sex and different codes. It is blasphemy to put the aura of modern science on the dead who were superstitious in ancient times.
