The elder was very pleased that there was a winner of the world's highest mathematics prize in China, especially since he also set a record as the youngest Fields Medal winner; the youngest person to win the Fields Medal before Lu Qiujian was the French mathematician Pierre Serre, who was born in 1926 and won the Fields Medal at the 1954 International Congress of Mathematicians in Amsterdam for his outstanding achievements in algebraic topology, when he was not yet twenty-eight years old.

For a long time after him, most of the Fields Medal winners were over the age of thirty, so much so that it was thought that her record could not be broken until the appearance of Lu Qiujian!

Lu Qiujian was born in 1983, because his birthday is at the end of the year, so he is not yet twenty-three years old, and this is the age when he has just graduated from the bachelor's degree, and he has won the highest award in the field of mathematics.

The elder regretted that Lu Qiujian had solved the Poincaré conjecture a little too late, and that it would have been better if he had completed this achievement in 2001, so that he could have personally awarded the Fields Medal medal to the young man at the 24th Congress of Mathematicians held in China in 2002.

The elder is a multi-talented old man, he is fluent in English, German, French, Spanish, Russian, Japanese and other languages, and even the obscure Romanian and Urdu are also good at it, and he has performed well in many fields such as Peking Opera, piano, erhu, etc., and he has used his talents to impress countless foreign people when he visited various countries.

You may have seen these on TV and in the newspapers, but few people know that he has published many scientific papers and received a lot of citations, and he has also done well in the field of mathematics, and even now he can help his grandson with mathematics.

In his graduation book, the students mentioned in their comments, "The doctor has been extremely intelligent since he was a child, and his grades in school are among the best in every column. He is especially good at mathematics and is the champion of the whole class. ”

When he attended the celebration of the first anniversary of Macao's return to the motherland, he asked the teachers and students of the school a plane geometry problem to verify the "five points of the circle", "Suppose: any star, five triangles, and the circumscribed circle intersect at five points. Verification: These five points are round. ”

In the standard mathematical language, the problem is as follows: in any pentagram AJEIDHCGBF, the intersection points of the respective circumscribed circles of △AFJ, △JEI, △IDH, △HCG, and △GBF are K, O, N, M, and l, respectively. Verification: K, O, N, M, L five points of the circle.

To solve this problem, you don't need advanced mathematical knowledge, you can do it with junior high school level geometry knowledge, but it is still a good mental training. If you are not resourceful and sharp, if you don't have the ability to think logically, even if you have advanced knowledge, you can't do anything.

Even Professor Yau Chengtong, the first Chinese to win the Fields Medal, took more than half an hour to solve this problem after getting it, which made him appreciate the subtlety of this problem.

Okay, put aside the matter of the elders for now, anyway, there are still many opportunities for Lu Qiujian to see the elders after returning to China, and everyone knows that there are countless people who are sending blessings to the elders. He can live a long life, let's come back and see how Lu Qiujian performed after winning the award!

Lu Qiujian and the other two laureates stood on the stage (I won't say which two, I always felt that it was not appropriate to replace anyone!), waiting for King Carlos I of Spain to present them with medals, and the last winner, Perelman, refused to come to Madrid to receive the prize he deserved.

It wasn't the first time in the history of the Fields Medals that the winners were absent from the ceremony. Coincidentally, the previous three were all related to Perelman's homeland.

In 1966, Lücchijian's old friend, algebraic Pope Alexander Grothendieck, boycotted the Fields Medal ceremony in Moscow to protest the Red Empire's military operations in Eastern Europe.

The winners of the 1970 edition, Sergei Novikov, and in 1978, Gregory Aleksandrovich = Margulis were restricted from leaving the country due to the Red Empire. It is not possible to travel to Nance, France and Vancouver, Canada to receive the prize.

However, they all have a reason, and this is the first time that such a non-political factor as Perelman has given up on receiving the award, and fortunately, King Carlos I of Spain has a wealth of mascots to act as a mascot. It was the experience of attending major events, and he casually picked up the medals and put them on the winners one by one.

When he walked to Lu Qiujian's side, Carlos I, after the usual blessing, suddenly leaned into Lu Qiujian's ear and whispered, "Dr. Lu, what do you think of Madrid?"

"Madrid is a beautiful and charming city, Your Majesty the King!" Lu Qiujian is not a secondary school, so he can only send praise at this time.

"I think so, too!" Carlos I smiled with satisfaction, still refusing to let go of Lu Qiujian's hand, "Then if that's the case, you might as well consider coming to live in Madrid! Real Madrid will definitely welcome you!"

Damn, I heard that King Carlos I of Spain is a fan of Real Madrid, but I didn't expect to be so loyal!

In front of him, it is difficult to say that the universities and scientific research institutions in Spain are not strong enough, Lu Qiujian had to use other reasons to politely refuse, "I'm very sorry, Your Majesty, I will quit football at the end of this year and return to China to transform into scientific research, I'm afraid I can only refuse your kindness!"

"Ah, that's a pity!" said Carlos I regretfully, seeing that he had no chance to end the conversation and walk to the next person.

In addition to the Fields Medal prize, the representative of the Clay Institute of Mathematics in the United States also presented him with a million dollars to solve the seven millennium mathematical problems, and this trip to Spain can be described as very fruitful.

At the end of the ceremony, it was time for the winners to give their acceptance speeches, and Lu Qiujian took the podium under the guidance of John Ball to begin his acceptance speech.

He first picked up the Fields Medal medal and looked at it carefully, the gold medal has a relief of Archimedes' head on the front and an inscription in Latin on the back: Mathematicians all over the world are proud to make new contributions to knowledge.

"I'll definitely take it with me, because maybe one day I'll go to Finland to play!" Lu Qiujian's opening remarks stunned the mathematicians present, and then caused a burst of laughter. (To be continued.) )
