I remember there is a formula to predict the world cup champion, which seems to be the year plus something.

Many people think that with reference to many objective factors, the predicted results will be more rational through a series of complex program operations that ordinary people can't complete. Actually, it's not. After all, it is people who actually operate the operation process. Their starting points are different, and the results are naturally very different. For example, Tolan, a professor of physics at Dortmund University in Germany, predicted that the German team would finally win the championship this year. He said that his prediction was mainly based on Germany's participation in the World Cup in previous years, such as Germany 1954, 1974 and 1990 winning the championship three times. After 1990, Germany ranked 3.7 on average in the four World Cups. Germany can win a championship trophy in four or five sessions on average. According to these laws, formulas of trigonometric functions made by him is used for calculation, the input year is =20 10/0, and the ranking value is 1. If we look at Professor Toland's method strictly from a mathematical point of view, the formula he invented is only consistent with the previous winning year or ranking in numbers, and there are few deep-seated laws, which are more like digital fortune telling than real scientific prediction. Even scientists who study the prediction of world cup champions can't be absolutely objective. Before the 2002 World Cup in Korea and Japan, scientists from the University of Warwick and the University of Ulster predicted the right to host the World Cup in a similar way. They consider the performance of each team in the World Cup qualifiers, international rankings, the unique advantages and disadvantages of each team, the distance each team travels to the competition venue, the length of rest time between each team's matches, and so on. These factors are input as numerical variables into a complex system including many formulas. Finally, they can predict the outcome of each game. Through this system, the result of the University of Warwick is that Argentina is the biggest favourite to win the championship, followed by Brazil. On the other hand, Brazil won the championship and Italy was the runner-up. As a result, Ulster University won half, but what neither side expected was that Turkey and South Korea won the third and fourth place respectively in that World Cup. It can be seen that no matter how sophisticated the calculus is, it is impossible to predict who will dominate the World Cup in South Africa. I'm afraid even God can't predict.
