From failed candidate to chief scientist

Chapter 172 The 49st Mersenne Prime Number

"M6*******"

"So this is a prime number between M57 and M885, which means it is after the 161th prime number, so this can be regarded as the 74th prime number."

So far, a total of 51 Mersenne primes have been discovered manually, with the help of computers, and through the GIMPS project.

Among them, it is not certain whether there are unknown Mersenne primes between M48 and M51. Now, Dongshan University Mathematics Research Center has given the answer, that is, there is.

"Teacher Jiang, upload this to GIMPS, and then apply for a bonus with them. If you don't pluck it, it will become white."

Lin Mo made a decision after confirming that there was no problem with the prime number.

"okay!"

Jiang Fanjun agreed and began to operate in front of the computer.

……

At the same time, far away in the United States at the University of Central Missouri, Curtis Cooper finished his day's work and routinely opened GIMPS.

Six years ago, Curtis Cooper found the No. 40 nine Mersenne primes through GIMPS.

And he has already joined the GIMPS operator and became one of the managers of GIMPS.

It sounds very high-end, but in fact GIMPS is just a website, and the so-called management is more like the moderators of domestic forums.

The information on GIMPS is completely public and can be viewed by anyone who logs in. It will display "how many users are using Prime95 online to find and verify Mersenne prime numbers", "which numbers have been detected", "how many "CPU invested in calculation", "What is the total calculation time", and "What Mersenne prime numbers are currently verified" and so on.

Curtis Cooper has logged into GIMPS every day for ten years, and routinely browses the information to see if there are any changes compared to the previous day.

Then, Curtis Cooper's eyes suddenly stopped at the currently verified Mersenne prime numbers, and there was an extra line there.

Curtis Cooper thought he was dazzled. He rubbed his eyes, blinked hard, and looked there again.

In the fourth to last line of the verified Mersenne primes, there is an extra line of records.

"The 49st Mersenne prime number, M6*******, was discovered by mo lin, from the Mathematics Research Center of Dongshan University in Xia State."

Curtis Cooper looked at the time and found it was just 5 minutes ago.

"Dongshan University? Mo Lin? A native of Xia?"

Curtis-Cooper found it a little unbelievable. How could this be possible? The name of the Xia people had never appeared in the discovery of Mersenne prime numbers.

Curtis Cooper was typing on the keyboard. He wanted to check how long it took mo lin to discover this new Mersenne prime number.

As an administrator, Curtis-Cooper can check the running time of every Prime95 applet connected to GIMPS.

This is related to the way GIMPS operates. GIMPS is equivalent to a general engineering contractor, subcontracting out the work of calculating and verifying Mersenne prime numbers in sections, and each computer running the Prime95 applet is subcontracting, contracting the calculation work of a piece of data.

Fortunately, subcontractors can choose the data segments they want to contract. When the subcontractors complete the verification of the data segments and find the new Mersenne primes, they will be automatically uploaded to the GIMPS main server and posted on the website. Live Update.

Therefore, choosing the data segment for subcontract calculation and discovering the possible Mersenne prime numbers is a technical job. Everyone who hangs Prime95 has carefully considered and selected the subcontracted data segment they want to verify.

So just hang up and leave the rest to God.

To use an old saying from the Xia Kingdom, it is up to people to make things happen.

So choice is important, and luck is also important.Then Curtis Cooper saw a moment that made his jaw drop.

"Seven minutes?"

"how can that be?"

Curtis-Cooper found it difficult to understand.

So how did Mo Lin do this?Is he so lucky?It only took 5 minutes to calculate the latest Mersenne prime number?

How can this be?Could it be that some cheating method was used?
But when it comes to discovering a new Mersenne prime number, how can one cheat when no one knows what the number is?What about cheating?If you know this number in advance, how can it be called cheating?

Curtis-Cooper once suspected that GIMPS had made an error. He carefully checked for a long time and verified the newly discovered Mersenne prime number for a long time before finally confirming that GIMPS had not made an error and that this number was indeed a new Mersenne. The prime number is correct.

The latest Mersenne prime number was discovered in 10 minutes. Curtis Cooper felt that there was no second answer except to blame it on luck.

This mo lin must be a person favored by God!The luck is so good!
Curtis Cooper posted on the GIMPS forum and announced the news in the official name of GIMPS.

"Mo Lin from Xia State has discovered the latest Mersenne prime number M6********. This will be the 49st Mersenne prime number. The original M74207281, M77232917, and M82589933 are postponed in order. Congratulations to Mo Lin."

As soon as his post was posted, it attracted countless replies. For a while, before his post had time to be topped, it already had the effect of being topped.

[Oh, my God, this is so incredible. After four years, someone finally discovered a new Mersenne prime! 】

【Xia Guo?Xia Guo can log in to GIMPS, but don't they have no internet? 】

【Moring?Good morning?The names of Xia people are really interesting.No wonder he was favored by God. 】

[Mo Lin, Xia Guo Dongshan University Mathematics Research Center, why do I feel that this name and this school are so familiar? 】

[I think so too. I remembered that the person who has been hotly discussed recently about solving NS problems seems to be also named Mo Lin. Do you think it is the same person? 】

[When you said that, I remembered that Mo Lin seemed to be from the Xiaguo Dongshan University Mathematics Research Center. This... they should be the same person, right? 】

[Oh my god, it’s really...does anyone of you have his contact information? Please confirm it quickly. 】

When Curtis Cooper saw this, he seemed to remember something. He hurriedly switched back to the GIMPS program and checked Mo Lin's registered email address.

Registration of a GIMPS account requires an email address, and as an administrator, Curtis Cooper can naturally check it.

Soon, Curtis Cooper found the email address used by Mo Lin when registering, and then hurriedly wrote an email and sent it.

Next, Curtis Cooper nervously waited for Mo Lin's reply.

He desperately wanted to know the answer, like a hundred claws scratching his heart, and couldn't wait to confirm the message. From time to time, he would open his mailbox and take a look to confirm whether he had received a reply.

But he was destined to be disappointed.

Because on the other side, Jiang Fanjun, who had discovered a new Mersenne prime number, was dancing happily and insisted on dragging Shan Gang, Lin Mo, and Zhao Bo along with him, saying that he wanted to treat them to a treat, and by the way, he would greet Zhao Bo.

At this time, several people were already eating heartily in a restaurant outside Dongshan University, and no one cared about the email issue at all.

They had no idea that at this time, on the other side of the distant ocean, there was someone anxiously waiting for their reply.
