The nine most wonderful theorems in mathematics: Bayes Theorem, Bote's Periodic Theorem, Closed Image Theorem, Bernstein Theorem, Fixed Point Theorem, Briansan Theorem, Brown Theorem, Bezu Theorem, Bosuke-ulam Theorem.
There is a basic tool in Bayesian statistics called Bayesian formula, also called Bayesian rule. Although it is a mathematical formula, its principle can be understood without numbers. If you see a person always doing good deeds, that person is probably a good person. In other words, when you can't accurately understand the essence of a thing, you can judge the probability of its essential attribute by the number of events related to its specific essence. ?
Expressed in mathematical language, the more events that support an attribute, the greater the possibility that the attribute will be established. Bayesian formula is also called Bayesian theorem, and Bayesian rule is a standard method to correct the subjective judgment (i.e. prior probability) of probability distribution by applying the phenomena observed in probability statistics.
Five interesting and wonderful theorems in mathematics;
1. A drunk can always find his way home, but a drunk bird may never get home. Suppose there is a horizontal straight line, starting from a certain position, there is a 50% probability of going left 1 m and a 50% probability of going right 1 m. What is the probability that you will eventually return to the starting point if you wander indefinitely like this? The answer is 100%. In the process of one-dimensional random walk, as long as the time is long enough, you can always return to the starting point.
2. If a local map is laid flat on the ground, you can always find a point on the map, and the point on the ground below this point is exactly the position it represents on the map. In other words, if you draw a map of the whole mall on the floor of the mall, you can always make an accurate "you are here" mark on the map.
You can never straighten the hair on the coconut.
At any moment, there are always two symmetrical points on the earth, and their temperatures are exactly the same as atmospheric pressure.
5, any given ham sandwich, there is always a knife to cut, so that ham, cheese, bread slices are just divided into two equal parts.
