It was half past eight in the morning and the lecture hall was almost full.
When Lu Zhou found a seat, he sat down in a low-key manner.
By 8:50 am, the lecture hall was full. So people even brought chairs inside or sat on the aisles to listen.
Even students from other schools ca.
It seed that Professor Ren Changming was quite popular.
At 9:00 am, the lecture finally began. Lu Zhou looked at the old gentlen on the podium and thought that he looked familiar. Maybe it was because Lu Zhou was too far away or the old man changed clothes, he really could not rember where he saw him.
When the powerpoint began, the female student who was sitting next to Lu Zhou finally stopped talking and reached for her notebook and pen.
The mont she saw Lu Zhou next to her, she was shocked.
As she looked at him, she asked quietly, “Student, are you, Lu Zhou?”
Lu Zhou nodded his head and said, “Yeah.”
That girl’s eyes lit up and she whispered with slight excitent, “You... You are from the 2013 mathematics class, Lu Zhou?”
“Yes... What’s up?”
“Oh, nothing,” said the young school girl as she shook her head.
Then why did you say my na!
Lu Zhou was speechless as he opened his notebook and started taking notes.
“...”
Lu Zhou: “...”
It might have been an illusion, but Lu Zhuo felt like the two girls sitting next to him were secretly watching him. They kept whispering and pointing at him.
Lu Zhou sighed.
Is this the troubles of being famous?
It feels...
Pretty good?
Fortunately, they did not talk about him for too long as they quickly changed topics.
Lu Zhou automatically shielded himself from external distractions by concentrating on the lecture.
When the professor finished his opening remarks, Lu Zhou had not missed anything.
“... We all know that pri numbers are natural numbers with only two factors. You might have known the first hundred pri numbers when you were in middle school. The twin pri numbers refer to pri pairs with a difference of 2, ie p and p 2 are both pri pairs, such as 3 and 5, 5 and 7, 11 and 13, 17 and 19, etc. As the number becos larger, the number of twins that can be observed becos fewer.”
“There are 8 twin pri pairs within 100, and there are only 2 pairs between 501 and 600. As the pri numbers increase, the next pri should be further and further away from the previous pri. The Goldbach’s conjecture asserts that there is an infinite number of pri numbers, which differ only by 2, such as 3 and 5, 5 and 7, and even this...”
Professor Ren wrote down a line of numbers on the blackboard.
[2003663613×2195000-1 and 2003663613×2195000 1]
He then turned around and laughed before he continued to speak.
“There is an infinite number of pris with a difference of 2. That is the guess of the twin pri numbers.”
So far, Professor Ren had only talked about simple stuff. Even Lu Zhou who had not studied the twin pri numbers yet could easily follow his speech.
It was the sa for the other first-year students. Whether they were mathematics enthusiasts or not, all of them listened with interest.
However, the content of the lecture soon beca difficult.
“... The twin pri number conjecture has always been a difficult problem in the field of mathematics. Just last year, there was a breakthrough in the study of the issue,” said Professor Ren as he smiled. He turned to the next page of the powerpoint before he continued, “The Chinese mathematician, Mr. Zhang Yitao, announced a proof that states there are infinitely many pairs of pri numbers that differ by 70 million or less. This was a huge breakthrough for the twin pri numbers problem.”
Professor Ren pushed his glasses and wrote the proof on the blackboard.
[Define theta(n)=lnn. if n is a pri number; define theta(n)=0 if n is a composite number. Take the function lambda(n)=..., define S1(x)=...,S2(x)=...]
[Verify S2−(log3x)S>0...]
[...]
When the students who were following the lecture saw the ever-increasing formula on the blackboard, there were unable to follow along anymore.
For example, the female student next to Lu Zhou had a look of “Where am I? What is this?” on her face. Within a second, the entire lecture had changed...
However, Lu Zhou was able to keep up with Professor Ren’s thought process.
Simply speaking, Mr. Zhang skillfully selected a lambda function and successfully proved that k>=3.5*10^6, and concluded that S2−(log3x)S1>0 holds.
In this way, by listing the first 3.5*10^6 pri numbers as acceptable sets, it could be proved that there were infinite numbers of infinite differences of less than 70 million.
“As of now, Mr. Zhang’s k>=3.5*10^6 has been reduced to k>=50. That is to say, the figure of 70 million has been reduced to 246. The rest of the work needs to be completed by latecors.”
Professor Ren smiled and thew the chalk on the desk as he said, “Perhaps, the great person who will complete this historic work is sitting in this lecture hall right now.”
“I look forward to that day!”
Clap clap clap!
The crowd applauded in thunder.
The audience was enthusiastic.
Even though they could not understand the content, they still clapped!
Of course, there were so people that understood and they were those that had a thoughtful expression on their faces.
For example, Lu Zhou.
The twin pri was just an introduction. Unlike an academic report eting, the intention of the lecture was only to stimulate the students’ passion for mathematics.
Professor Ren talked about the Goldbach conjecture from the twin pri conjecture, and from the Goldbach conjecture, he talked about the current developnt of dostic number theory and so relatively advanced research results.
It was safe to say that this professor was quite skilled.
The professor took obscure topics and made them seed interesting for beginners.
However, the content of the second half of the lecture was much less interesting than the content of the first half of the lecture. So, Lu Zhou did not listen carefully. His mind was still stuck on the proof of the twin pri.
Lu Zhou recalled the discovery in the library while he stared at the blackboard. He frowned as he felt like there was sothing in the dark that and whenever he tried to catch it, it would run away...
Once the lecture was finished, the students from the student union took a na list and passed it around for the other students to sign.
After Lu Zhou finished signing it, he wanted to rush to the library but he was blocked by the schoolgirl sitting next to him.
“Student, student, wait a second. Um, can I add your QQ?”
Lu Zhou did not want to waste his ti, so he wrote down his QQ number on a piece of draft paper. He did not even give her a chance to speak before he quickly walked away.
However, when he walked out of the lecture hall, he was stopped by another person.
This ti it was not soone random, but Professor Ren.
From the smile on the old gentleman’s face, it was obvious that he had waited for Lu Zhou for a while.
“Ah, young man, we et again.”
Lu Zhou: ? ? ?
We’ve t?
I think we have t actually...
The old gentlen did not even wait for Lu Zhou to speak before he asked, “Young man, are you interested in rocket developnt?”
Lu Zhou was still thinking about the pri numbers problem and he was shocked by this question.
What the f*ck. Are you asking to be an astronaut?
How is that possible?
Lu Zhou smiled awkwardly, “Professor, I don’t want to go to space yet.”
