Chapter 59 Where is the troublemaker?
Professor Zhuge of the Department of Mathematics of Qingdao University determined to become a mathematician when he was young. His idol was Hua Luogeng, so when he was in college, he changed his name to Zhuge Xuegeng.
At this time, Professor Zhuge had just finished giving a lecture and was surrounded by several students discussing issues.
"Professor, I have a question about the initial value of a compound fractional differential equation..."
Professor Zhuge glanced at it: "Do you still need to ask me this question? It's so simple! I have written such a paper, you will understand after reading it.”
Professor Zhuge said and wrote the title of the paper.
"Professor, what you just said is that the general nonlinear one-dimensional average curvature equation is a positive solution. Here is an accurate number, but..."
"Your solution here falls into a trap The misunderstanding should be like this..." Professor Zhuge wrote a few strokes on several key points.
"Professor, regarding the sharp non-existence result of the four singular source curvature equations on this rectangular torus, the result of my calculation is this, please take a look."
Professor Zhuge reads He glanced at it and said: "It's great to be able to do this. Regarding the curvature equations of the four singular sources on the rectangular torus, someone in the department happens to be working on this topic. I will sign it for you, and you can go to them to discuss it. Maybe there will be new inspiration.”
"Professor, I have listed a few key points on the simple zero-point properties of some holomorphic functions on the modulus space of the torus. Please help me check them."
Professor Zhuge read it carefully and frowned. Brow said: "When we discuss holomorphic functions on the modulus space of a torus, we are actually studying how these functions change on various shapes and sizes of the torus. The modulus space itself is a complex mathematical object, It describes all possible torus structures..."
The next student came over and handed over a small note with M24, 036, 583 written on it.
"Professor, look, I discovered a new Mersenne prime number!"
"Where is the troublemaker!" Professor Zhuge slammed the table.
New Mersenne primes discovered? This is lower than the probability of winning the jackpot by buying a lottery ticket!
Why don’t you go to heaven!
Professor Zhuge raised his head, wanting to see who was coming to cause trouble.
At first glance, it was not the graduate students I brought with me.
Looking carefully, it’s Zhang Wei!
"Classmate Zhang Wei, why are you here? Are you interested in our Mathematics Department? Our Mathematics Department welcomes you!"
"I'm also interested in your 170-legged girl!" Zhang Wei I thought to myself.
Then Zhang Wei pointed to the note: "Professor Zhuge, I just discovered a new Mersenne prime number."
"Zhang Wei, don't say this nonsense. , do you know that humans have only found 40 Mersenne primes so far!"
"This should be the 41st!" Zhang Wei said confidently.
Professor Zhuge frowned and looked at the numbers on the note carefully. 24,036,583 seemed to be a prime number.
“Where did you get this number?”
“GIMPS!”
“Is that the Internet system that the United States has? The recent six Merson primes seem to be This is what I found. Have you verified it?" Professor Zhuge asked.
“Not yet. My broken computer definitely cannot verify it. If it is uploaded to the CIMPS server, I don’t know how long it will take for the verification results to come out.”
"So you came to me just to verify whether this number is a Mersenne prime?"
Zhang Wei nodded: "The computer in the Department of Mathematics at Tsinghua University must be much faster than mine!"
"The Department of Mathematics at Tsinghua University has some computers that are faster than ordinary computers, but you have to queue up to use them." Professor Zhuge continued.
“How long will it take to wait in line?”
“The fastest one, if you apply now, you will have to wait for a week!”
"So long!" Zhang Wei said a little disappointed.
Professor Zhuge went on to explain; "What we do in mathematics research is different from other disciplines. For example, the graphene you made can be measured with a microscope and a spectrometer, and you will know whether it is successful or not.
But testing the results of mathematical research requires a lot of calculations, which can only be verified by computers. Many projects have to verify one step at a time. Otherwise, if the previous step is wrong, the subsequent research will definitely be wrong. Wrong."
"Professor Zhuge, can you give me a back door?"
"How about coming to our mathematics department next semester?"
"
"I'm actually not very good at math. I almost failed the advanced math test last semester!"
"It doesn't matter if you fail. I'll find a teaching assistant to give you one-on-one tutoring. As long as you come." That’s it!” Professor Zhuge said with a smile.
"Professor, the graphene I made has nothing to do with your mathematics department! If I really came to the mathematics department, I wouldn't be able to use my expertise!"
Zhang Wei hit He looked careless and continued: "Otherwise, if this number is really a Mersenne prime number, even if it is a research result of the Department of Mathematics, I can just name it when it is published!"
When publishing a paper There is a distinction between first author and second author, and the same can be done when publishing new scientific discoveries. For example, you can say this: Zhang Wei from the Department of Mathematics of Tsinghua University discovered the 41st Mersenne prime number. With such a saying, the mathematics department gets a lot of credit. It has done nothing but made discoveries in vain.
If it were anyone else, Professor Zhuge would be too lazy to pay attention to him, but Zhang Wei is a future Nobel Prize scholar. With this deal, people would come to him for help, and he would be embarrassed to refuse.
As the saying goes, where there are people, there are rivers and lakes, and the academic world itself is a big mess. We are all highly educated intellectuals, and we must be worldly.
Thinking of this, Professor Zhuge said: "The computers in the Mathematics Department do not have extra time for you, but I can help you think of a solution from other places.
Our Department of Mathematics at Tsinghua University has always been in contact with many scientific research institutes. I can help you ask whether their supercomputers have sufficient time.
Your number is 2 raised to the power of more than 24 million. Let me think about it. It must be within ten million digits. If a supercomputer squeezes some time, it should be able to calculate it for you. ”
“Can I use a supercomputer? Is it the Milky Way? "Zhang Wei asked immediately.
"The Galaxy National Defense Technology is a military product, and we can't use it. Let me ask Sugon for you first. Sugon 4000 is currently the fastest supercomputer in China, capable of 4.2 trillion operations per second! "
Professor Zhuge said, picked up the phone, dialed a number, and after asking some questions, said:
"Not only Dawn 4000, but Dawn 3000 and two... Taiwan Dawn 2000 is fully booked. Don't worry, I'll ask the National Computer Engineering Center again. Although the calculation speed of the Sunway supercomputer there is far less than that of Dawn, it still has a calculation speed of 384 billion times per second. ”
"It turns out that the divine power at this time is not as good as the dawn!" Zhang Wei showed a surprised expression.
As a reborn person, Zhang Wei still remembers the Sunway TaihuLight supercomputer, which defeated American supercomputers many times and became the world's number one supercomputer.
Twelve years later, Sunway TaihuLight can reach a peak computing speed of 1.254 billion times per second. The current Sunway generation computer has only a calculation speed of 384 billion times per second, a difference of 330,000 times. Zhang Wei couldn't help but sigh in his heart, China's technological progress is so fast!
After a while, Professor Zhuge put down his mobile phone and said: "After ten o'clock tonight, there will be free time at Shenwei. I will send this number to you later and let them verify it for you. Let's hear the results tomorrow. !”
“Thank you very much, Professor Zhuge!” Zhang Wei thanked him quickly.
...
Zhang Wei returned to the dormitory, where the autistic man was lying on the bed, admiring the empty ceiling. Ye Haotian was sitting at the desk, holding a piece of seaweed in his mouth and writing furiously in his hand.
“Hey, we’re eating seafood!” Zhang Wei smiled and came over.
"Don't tell me, the more you eat this seaweed, the more addictive it becomes. Once you eat it, you can't stop! Buy me a few more packs when I go home during the summer vacation."
Ye Haotian is already convinced. I accepted the setting that seaweed is seafood.
"It's still in use during the summer vacation. I'll go to the supermarket to have a look later."
"The taste is different!" Ye Haotian continued: "I have bought other brands, but the taste is not the same as the one you bought. The key is The brand you brought is not available in our supermarkets.”
“This is indeed a brand unique to us. Give me your address and I will send you a box when you get back during the summer vacation.” He spoke.
"I can also give you the address." The autistic man's weak voice came from the bed.
“Beer is liquid and cannot be sent!” Zhang Wei spread his hands.
The autistic person is very disappointed and turns his head to continue being autistic.
Zhang Wei continued to ask Ye Haotian; "What are you writing about?"
"Study experience, I just attended a lecture on the mental health of college students, let me share your experience!"
"Attending a mental health lecture? Are you mentally ill?" Zhang Wei asked jokingly.
“You are a psychopath!”
"It's not a psychopath. Why are you participating in this thing?"
"It's not that Ma Jiajue who caused the trouble. Now universities across the capital are promoting mental health education for college students, requiring everyone to attend classes."< br>
Zhang Wei quietly pointed at the autistic person: "Why doesn't Chen Ming write?"
"He doesn't need to receive mental health education. It won't be cured even if he does!"
"I think Chen Ming should listen to this mental health education. I heard that this Ma Jiajue is very good in physics, just like Chen Ming. He even won the second prize in the National Physics Competition!"< br>
"I am the first prize!" the autistic man's voice came again, with a hint of disdain in his tone.
The first prize looks down on the second prize, the perfect chain.
Zhang Wei then said: "I also heard that this Ma Jiajue won the title of Three Excellent Students in the Province!"
"I am not." The voice of an autistic person sounded again.
"Me neither! I haven't even received half a certificate since I entered high school!" Zhang Wei said and looked at Ye Haotian.
A high-quality human male who won the title of Three Excellent Students in the Province for three consecutive years in high school.
Ye Haotian's face suddenly drooped: "I heard it, you are nodding at me again!"
This chapter has three thousand words, although the previous question and answer session with the professor was all real advanced mathematics questions , but considering that you can’t understand it, it must be regarded as a low word count, so I wrote a few more to make up for it. Is he a conscientious author? Is it worthy of your recommendation, voting and reward three times in a row? In addition, regarding Ma Jiajue, those born after 2000 have probably never heard of him. Commentators can give them some popular science.
