For example, in practical use, when pi is 28 digits after the decimal point, the circumference of the solar system can be calculated to atomic order! Mathematical hail can be said to be similar to a simple game!

But if they are proved, mathematics will really take a big step forward.

Like Goldbach's conjecture, mathematicians found many new tools and methods in the process of proving him, which greatly promoted the development of mathematics!

Some people say: "Goldbach conjecture is like a duck laying golden eggs, which can hatch a new way of thinking", that's what it means!

Other world problems that seem to have no practical use use use this role!

About pi, calculating it is also of great significance!

Before the invention of the computer, calculating pi was a contest of algorithm and intelligence. Mathematicians invented many formulas for calculating pi and many methods for calculating series!

After the invention of computer, calculating pi is not only an algorithm and intelligence competition, but also an effective method to test the performance of computer. For example, the popular Super pi and the newly developed pi_fast are both effective software for testing the performance of computer cpu!
