He argued that if the initial conditions were a little small and the result would be very unstable, he would call it a butterfly effect.. Just like we throw the dice two times, no matter how we try to throw it, the two physical phenomena and the number of points thrown are not necessarily the same. Why did Lorenz write this paper? The story happened in the winter of 1961, and he used to operate the weather computer in his office as usual. Usually, he only needs to input meteorological data such as temperature, humidity, pressure, etc., and the computer calculates the possible meteorological data at the next moment according to three built-in differential equations, so it simulates the weather change diagram. On this day, Lorenz wanted to learn more about the subsequent changes in a record. He added the weather data at a given moment to the computer and calculated more results. At the time, the computer was slow to process the data and enough to have a cup of coffee and a chat with friends before it turned out. After an hour, the result came out, but he was dumbfounded. As a result, compared with the original information, the initial data is similar, and the greater the data difference, the more like the latter two different information. The problem is not in the computer, the problem is that he entered 0.000127 of the data, and these slight differences make a great difference. So its impossible to predict the weather for a long time. Reference: a grass gourd (2) - Yuanzhe Science Education Foundation 2.
