Let's start our Riemann conjecture journey with a short story. This story happened about 70 years ago. At that time, there was a famous mathematician in England named godfrey hardy (1877- 1947). In my opinion, he is a brave man in British mathematics for 200 years. Why do you say he is a brave man? Because in the seventeenth century, there was a heated debate between British mathematicians and continental European mathematicians. The theme of the debate is who invented calculus first. On the one hand, isaac newton (1642- 1727), a great British scientist, and on the other hand, gottfried leibniz (1646- 1765438), a philosopher and mathematician from continental Europe, were the core figures involved in the debate. After this argument, it goes without saying that both sides are exhausted, which also hurts harmony and leaves a long-lasting sequela. Since then, many British mathematicians have begun to reject the mathematical progress in continental Europe. An argument has evolved to such a point that the collective honor and dignity of British mathematics and Newton's great reputation have become negative assets, and British mathematics has declined in conservative dance steps.

This downhill road is 200 years.

Under this background, when the complex number theory is still regarded as a dangerous concept from the European continent by some British mathematicians, Hardy, a native British mathematician, took a keen interest in the mathematical conjecture with complex variables from the European continent (still Germany), actively studied it, and-as we will introduce later-achieved results that shocked the mathematical community in the European continent.

Hardy has a very good mathematician friend in Denmark named harald bohr (1887- 195 1). He is the younger brother of the famous quantum physicist niels bohr (1885- 1962). Bohr is also interested in Riemann conjecture, and studied Riemann conjecture with German mathematician Edmund Landau (1877- 1938) (their research results will also be introduced later). Hardy likes to spend his summer vacation with Bohr and discuss Riemann conjecture together. He often stays until the end of his holidays before returning to England. As a result, once he arrived at the dock, he found that there was only one boat left to ride. No way, he had to bite the bullet. Taking a boat in the sea of Wang Yang is no joke. If done well, it's romantic and exciting. If you don't do it well, you will die. Passengers who believe in God are busy praying for God's blessing at this time. Hardy is a man who firmly does not believe in God. Not only did he not believe in God, but one year he included proving to the public that God did not exist in his six wishes of that year, ranking third (the first one was to prove Riemann conjecture). But Hardy has not been idle in this do or die. He sent Bohr a short postcard with only one sentence:

"I have proved the Riemann conjecture!"

Did Hardy really prove Riemann conjecture? Of course not. Then why did he send such a postcard? After returning to England, he explained the reason to Bohr. He said that if his ship really sank that time, people would have to believe that he really proved Riemann's conjecture. But he knew that God would never give him such a great honor-a man who firmly didn't believe in God-so God would never let his ship sink.

God didn't want Hardy's ship to sink. Since then, more than 70 years have passed, and the stingy God still hasn't found anyone who can bear such a great honor.
