The Science Fiction World of Xueba

Pang Xuelin was walking on the road on the Harvard campus, although Pang Xuelin had already been to Harvard once when he was touring various universities in the United States.

But for this world-renowned top university, Pang Xuelin is not familiar with the roads on campus.

He was just about to find a seat at the Harvard Business School in the lobby, when a voice suddenly came from behind him.

"Xuelin Pang, is that you?!"

When Pang Xuelin turned around, he saw a middle-aged Caucasian man in his early fifties calling him.

"Professor Gross, long time no see!"

Pang Xuelin laughed.

Benedict Gross, member of the American Academy of Sciences, tenured professor of Harvard University, Gross graduated from Harvard in 1971, received a master's degree from Oxford University in 1974, and received a doctorate from Harvard University in 1978, under the tutelage of Professor John Tate .

After graduation, Gross taught at Princeton University and Brown University successively, and then served as a tenured professor at Harvard University in the United States since 1985. Professor Gross's main research direction is number theory and algebraic geometry, and he has made many important contributions to mathematics. Marshall Award, MacArthur Award and the 1987 Cole Prize in Number Theory awarded by the American Mathematical Society.

This is also a big shot, whether in the real world or the last time he went to Harvard to give a report, Pang Xuelin has met him, but the two sides have not had deep contact.

"Pang, long time no see. Why did you come to Harvard? Didn't Pierre say that you and Witten went back to China to conduct string theory research?"

Gross asked curiously.

Pang Xuelin said with a smile: "I just came to the United States a few days ago, and I just went through the entry procedures for a part-time professor at Princeton University. I came here today just to find a friend. By the way, Professor Gross, can you tell me how Harvard Business School go?"

Gross smiled and said, "You're going to Harvard Business School? Come with me, and I'll take you there."

"Okay, Professor Gross, I'll trouble you then!"

Along the way, the two chatted while walking.

"Pang, why do you want to engage in theoretical physics? I have been studying your Ponzi geometry for a while, and I feel that this theory can be further studied in depth, and it is entirely possible to use it to solve many classic problems in number theory. ,

Such as ABC conjecture, Goldbach conjecture and so on. "

"Personal interest, string theory is very interesting, pure mathematics research can be done alone, but in theoretical physics, there are many things to consider... In the past few years, my research focus has been on pure mathematics, now change to another field Study it, it feels pretty good..."

"Haha, that's true. It's a good thing you didn't continue to study Ponzi geometry. If you come up with some amazing results, it really won't make a living for mathematicians all over the world. Now many people are learning Ponzi geometry. Trying to solve more problems on the basis of Ponzi geometry..."

Pang Xuelin smiled, but did not answer.

It's a delicacy, just try it once or twice, if you eat it every day, no one will get tired of it.

This is the case with his Ponzi geometry theory, which has been published several times in the real world and in the world of Wandering Earth. Now in the world of rural teachers, he was just an ordinary rural elementary school teacher before. On the basis of Ponzi geometry, it is meaningless to take out the proof paper of the ABC conjecture.

Anyway, for more than half a year, Pang Xuelin felt that it was more meaningful to focus on the structure of M theory.

At least in the field of theoretical physics, he considers himself a top physicist.

Instead of sending Pang Xuelin to Harvard Business School and leaving, Gross took him directly to the office of a professor he knew at Harvard Business School.

"Pang, let me introduce you. This is Professor Robert Merton, who is also my good friend. Merton, this is Professor Pang Xuelin from Tsinghua University in China..."

Robert Merton smiled and said: "Gross, I don't need your introduction, the amazing Chinese kid, the prover of Fermat's last theorem, Pang, it's a pleasure to meet you!"

"Professor Merton, nice to meet you too!"

Pang Xuelin smiled and shook hands with Robert Merton.

What Pang Xuelin didn't know was that Professor Merton had long been well-known in the field of economics. He was a major in engineering mathematics and later switched to economics. He won the Nobel Prize in Economics in 1997.

His book "Continuous Time Finance" developed financial mathematics and financial economic theory starting from a model in which agents can adjust their decisions in continuous time.

His theories have had a huge impact on subsequent monetary management, financial intermediaries, investment banking, corporate finance, and capital budgeting procedures.

"Pang, are you here to find Mu Hui Wang?"

Pang Xuelin was slightly taken aback, and asked in confusion, "Professor Merton, how do you know?"

Robert Merton said: "In the entire Harvard Business School, there is only Mu Hui Wang, a Chinese. I can't think of any other reason for you to come here suddenly, except to find her."

Gross on the side smiled and said, "Pang, since Merton knows who you are looking for, I won't stay any longer. I have something else to do, so I'm leaving first!"

"Professor Gross, thank you for today!"

"You're welcome! Next time I'm free, I'll go to Princeton to find you. I hope I can share with you my experience in Ponzi's geometry theory!"

"no problem!"

After Gross left, Merton looked at the watch on his wrist and said, "Pang, it's half past twelve, and the morning class is almost over. Let's go, I'll take you to the auditorium to find Mu Hui!"

Pang Xuelin smiled and said, "Professor Merton, I will trouble you then!"

Pang Xuelin followed Merton to the door of a lecture theater. It was just the end of get out of class time. The students filed out of the classroom and saw Merton leading Pang Xuelin standing at the door. Many students greeted Merton first, and then His eyes swept over Pang Xuelin, and he always felt that this black-haired and yellow-skinned person was a little familiar.

Some people seem to recognize Pang Xuelin, but they are not familiar with Pang Xuelin, and their eyes just stay on him for a while, and then whisper to their companions.

Occasionally, I can hear words such as Chinese Pang and Fermat's last theorem.

After a while, a tall girl with long hair and shawl, wearing a plain jacket and jeans, hurried out of the classroom.

She lowered her head, as if she was thinking about something, she didn't notice Pang Xuelin and Merton standing at the door of the lecture hall at all.

"Little Hui!"

Pang Xuelin said.

Wang Muhui shuddered, thinking that she had auditory hallucinations, and raised her head subconsciously, and saw Pang Xuelin and Professor Merton standing together, looking at her with a smile.

"Brother Pang!"

Wang Muhui rubbed her eyes, and a look of disbelief flashed in her eyes. The next second, she jumped into Pang Xuelin's arms like a sucking swallow throwing herself into the forest.
