Chapter 62 Are you paying public food?
Professor Zhuge is answering students' questions again.
“Professor, regarding the geometric Bogomolov conjecture, I have several opinions. In the algebraic variety defined on the field of rational numbers, are there an infinite number of rational points, and is the distribution of these points inconsistent with some geometry? Variables are related, I think we can try a new idea..."
"Professor, I read Academician Zhang's "Nonlinear Analysis of Boundary Value Problems of Heat Flow and Harmonic Mapping", and I have several points. I don’t quite understand. One is to solve the harmonic mapping under the given boundary conditions of the source area and the target area, and the other is the fixed boundary value and the normal derivative on the fixed boundary..."
"Professor, you see , I discovered a new Mersenne prime!" A note was handed over.
"Where is the troublemaker!" Professor Zhuge slammed the table.
Same recipe, same taste!
Professor Zhuge raised his head and saw Zhang Wei's face.
There are the same people!
"Zhang Wei, why are you here?"
"Professor Zhuge, I discovered a new Mersenne prime number."
"Time went back? Did I travel back in time? Did "A Brief History of Time" come true?" Zhuge Xuegeng was a little confused.
"Zhang Wei, I know that you have discovered a new Mersenne prime number. Everyone in Qing Dynasty knows about it, even Peking University next door knows about it." Zhuge said.
"Professor, that happened last week, let's talk about this week. I discovered a new Mersenne prime number." Zhang Wei pointed to the small piece of paper.
"Found another one? I said Zhang Wei, we are engaged in academics and can relax occasionally, but we can't joke around! Mersenne prime numbers are not cabbage, you can buy a cart of them in any market! This thing may not be found even once a year.”
Zhuge Xuegeng said, subconsciously looking at the new numbers provided by Zhang Wei.
M25, 964, 951 are really different from last time. And this 25,964,951 also looks like a prime number.
Could this really be a Mersenne prime?
"Professor, how dare I joke with you! This is really the Mersenne prime number I just discovered. But I need your help to verify this. Contact the Computer Engineering Center and use Shenwei again. ! ”
“Didn’t you just find a Mersenne prime last week? Why did you find another this week? ”
"Isn't this a coincidence!" Zhang Wei said with a smile.
Zhuge Xuegeng took another look at the note in his hand. The previous number was 24,036,583, and this number was 25,964,951. The difference between the two is not big. Converted to Mersenne primes, the difference should be within one million digits.
From a scientific perspective, it is possible for two Mersenne primes that differ by only one million digits to be discovered in a short time.
Thinking of this, Zhuge Xuegeng nodded: "Okay, let me ask the supercomputer if there is any extra time!"
......
"Professor Zhuge, the number you asked me to verify is indeed a Mersenne prime number. This number has a total of 7,816,230 digits. I have put the relevant data into the USB flash drive and will send it to you shortly. Will someone send it to you?”
“Don’t bother, I’ll go get it myself!” Professor Zhuge felt like his mind was buzzing, as if he couldn’t distinguish between east, west and north.
"It's really a Mersenne prime! But last week, he just found a new Mersenne prime! Are these Mersenne primes so easy to find? How about I try too?"
< br>Professor Zhuge looked at the computer in his office. It seemed that he had just bought it last summer. The configuration was quite good.
Scientists all have strong practical abilities. Professor Zhuge immediately logged into the official website of GIMPS and downloaded Prime95.
Then he successfully crashed his computer!
……
The teaching assistant placed a latest summary of global mathematics research results on John Coates’ desk.
John Coates read the ten lines at a glance, and then frowned.
"Professor, do you have any questions?" the teaching assistant asked.
"It seems you didn't work hard! The Chinese discovered the latest Mersenne prime number. I saw it two days ago. You repeated the statistics. Not only that, you even got the number wrong. I remember that number started with 24 , but what you wrote here begins with 25!”
“Professor, there may be a misunderstanding here. The Mersenne prime number you saw before is the 41st Mersenne. Prime numbers, but that's not the latest one. The latest one is this, the 42nd Mersenne prime number M25, 964, 951. "Is a new Mersenne prime number discovered this week? " John Coates took another look at the message, and then denied it: "No, the person who discovered Mersenne primes here is clearly the same person, Zhang Wei from the Qing Dynasty in China, I remember this name!"
John - Coates felt that since the names of the discoverers were all the same, the teaching assistant must have not worked hard and just updated the numbers but forgot to update the names of the discoverers.
But the assistant replied: "Professor, I checked, the 41st Mersenne prime number and the 42nd Mersenne prime number were discovered by the same person, Zhang Wei from Qingda University in China!"
" The same person discovered two Mersenne primes in just two weeks? "Are you kidding me?" John Coates stared at his assistant and found that his expression did not look like he was joking.
In human history, from 200 AD to the beginning of World War I in 1914, only 12 Mersenne primes were discovered.
From the 13th to the 34th Mersenne prime number, it took humans a total of 82 years, an average of three years, four months and two weeks, to discover a Mersenne prime number.
After the GIMPS system was introduced, it took humans seven years from the 35th Mersenne prime to the 40th Mersenne prime, which means that on average it still takes more than a year to discover a Mersenne prime. .
Nowadays, a guy suddenly appears, one discovered every week?
The key point is that this guy is still Chinese. In the eyes of John Coates, the Chinese are very backward in mathematics research!
“No, it has nothing to do with China, it’s because the GIMPS system in the United States is good enough! Maybe it’s because the GIMPS system has been upgraded, that’s why the 42nd Mersenne prime was discovered so quickly. This must be the case, so it’s still the United States My technology is amazing!”
……
United States, Electronic Frontier Foundation.
"When was our GIMPS system upgraded? Why didn't I know?" President Barlow asked with a puzzled look.
"President, as far as I know, the GIMPS system has not been upgraded recently." His subordinate said.
"Then why was another Mersenne prime number discovered in just one week? The key is still the same person? Is there a bug in our system?"
"President, we have verified it. The M25, 964, and 951 that the Chinese just discovered are indeed Mersenne primes. Even if there is a bug in our system, mathematics will not lie."
"What is going on with the GIMPS system? , we have been running for eight years and only found six Mersenne primes in the first seven years. Why have we found two in the last two weeks? "
"Perhaps the Chinese is lucky! Or maybe he used a mysterious power from the far East? Such as divination!"
"Divination calculates Mersenne prime numbers? You can also think of it? Bruno said, I'm in vain Burned to death?" President Barlow cursed secretly.
At this time, the secretary knocked on the door again and walked in.
"President, we received an email from Zhang Wei, the Chinese who discovered the 42nd Mersenne prime number. He asked us to transfer $50,000 to the account last time!"
Need money again? No more running! It's indeed the same person!
…
New week.
"Professor, look, I discovered a new Mersenne prime number!"
Another note was thrust in front of Zhuge Xuegeng.
Hearing this voice, Zhuge Xuegeng realized that the shameless guy was causing trouble again!
He raised his head, and what appeared in his pupils was Zhang Wei!
"What is going on? One Mersenne prime number a week?
Once a week, you come to me to pay the public food!"
The second chapter was delivered today, thank you Monthly tickets for everyone. For those who have read the book for the first time and feel that it is not enough, you might as well read "Rebirth of the Industrial Tycoon" which was written before the book was passed. I’ve added it to my recommendations later.
