Chapter 399 Einstein’s Gravity Field Equation
New semester, new atmosphere.
Yanhua University has two major development-related events, one is the establishment of a medical science center in the School of Life Sciences, and the other is the establishment of a particle mathematics research center in the School of Science.
The entire university is discussing the construction of two scientific research institutions and what impact it will have on the future.
This is relevant to every student.
Scientific research institutions in universities will tend to be in the direction of education, and students will have more choices after graduation. For example, seeking a mentor who works in a scientific research center is equivalent to studying for a master's degree in a scientific research center, and then pursuing a doctoral degree after graduation, or Just stay and work in the scientific research center.
etc.
The Medical Science Center is preparing to be built, and the building drawings have been designed. The only thing left is to wait for the official start of construction in spring. Equipment for the large laboratory is being ordered, as well as some other internal work.
For example, talent introduction is already in progress.
The Particle Mathematics Research Center is still under planning, mainly because the school has no autonomy and everything depends on the support of the Science and Technology Department.
Many people hope that Zhao Yi will pay attention to this matter. The Science and Technology Department allocates funds for Zhao Yi, but Zhao Yi does not want to get involved in this matter. He only made a promise that when the Particle Mathematics Center is established, his office will be opened. Just move over.
He reluctantly agreed to this matter. He mainly had an office, which did not conflict with the office of the School of Science.
Zhao Yi doesn't want to get involved in the Particle Mathematics Research Center. One is that he doesn't want to increase his workload. The problem of the office also involves the 'location'. The Particle Mathematics Center can only be built on the west side of the university, and only there is open space, and on the west side It's close to the business school, but a little far from staff dormitories, general teaching buildings, biomedical research institutes, etc.
Although the distance is only a few hundred meters, running two more steps always feels a bit depressing.
The first week of school.
Zhao Yi's life is relatively busy. He went to the National Science and Technology Award Conference and received the 'First Prize in Natural Science'. Zhang Wei from the laboratory, as a representative, received the 'Second Prize in Science and Technology Progress Award', which was the same as last year. Compared with 2018, the awards received by the laboratory are one notch lower, but being able to receive awards for two consecutive years is considered an achievement.
Zhao Yi's feeling was a bit calmer. Everyone in the laboratory was very excited. Others in the institute could only envy Zhao Yi's laboratory. They couldn't even get a prize even if they wanted to.
Reports in the media were muted.
Most media just talked about it, "Zhao Yi won the Natural Science Award for proving Goldbach's conjecture."
Then, no more.
Probably because everyone is used to it, it is no surprise that Zhao Yi has won awards for several consecutive years.
This is also good news.
When there are not too many media reporters to disturb him, Zhao Yi's life becomes a lot easier and he can enjoy a few days of normal college time.
weekend.
Zhao Yi was still busy. His plan was to go to the Mathematical Science Center of Shuimu University to discuss the issues of 'cosmology' and 'positive energy in the solution of Einstein's equation' with Qiu Chengwen.
Qiu Chengwen is a very good mathematician and has made great achievements in theoretical physics research. He proved that any solution to Einstein's equation must have positive energy.
Qiu Chengwen must have a deep understanding of this aspect.
Zhao Yi felt that discussing it with Qiu Chengwen might help his particle mathematics research.
When he called me, the trouble came again. Qiu Chengwen invited him to give a lecture at Shuimu University. "The Chen Jingrun lecture series is going to be held at the weekend. The main core is the problem of complex sieve methods. No one is more suitable than you, a master of number theory." "
After he finished speaking, he added in a distressed tone, "If you don't come, I will have to come."
Zhao Yi knew that Qiu Chengwen was "selling out his bitterness", but thinking that the other party would review his papers and help him when there was anything he could do, and his personal relationship was also very good, it would not be good to shirk it anymore, so he thought for a while and simply said , "Okay. When the lecture is over, let's discuss particle mathematics together. I'm very interested in cosmology and Einstein's equations."
"It's great that you can come. No problem. Academically, we just need to communicate more." Qiu Chengwen readily agreed.
What Qiu Chengwen said at the end was based on "Academics is about communication", which made Zhao Yi deeply touched. His academic achievements are indeed remarkable. It can be said that they have reached the top level in the world, but the more he does research, the more he discovers , my knowledge is still a bit poor.
When academic research reaches an extremely advanced level, any small branch will use a huge amount of knowledge. Ordinary people may not be able to complete a small branch by spending their whole life studying.
Zhao Yi found that his research on particle mathematics was limited by the 'amount of knowledge', and all his thinking was based on the knowledge he had in his mind.
That's the limit.
In fact, it is the same as understanding multi-dimensional space.
Even top mathematicians use mathematical techniques to understand space above four dimensions, rather than being able to construct real effects in their minds like three dimensions.
This is the limit of the current amount of human knowledge.
Human beings are limited to the three-dimensional universe, and all the knowledge they acquire is within the framework of the three-dimensional universe. Without knowledge and insights beyond the three-dimensional universe, how can we know what a multi-dimensional space looks like?
That’s why some people say, “Human beings can never imagine what space above four dimensions looks like.”
Zhao Yi found that what he needed to do was to acquire more knowledge. As he continued to study particle mathematics, the knowledge he needed was no longer just what could be found in books. He had to do more academic exchanges and get to know other top mathematicians and physicists. As a scientist, his cognition and research in related fields may enlighten his thinking.
…
weekend.
Shuimu University held the "Chen Jingrun Lecture Series", and Zhao Yi came to the Department of Mathematics of Shuimu University as scheduled.
The Mathematics Department of Shuimu University is full of sincerity towards Zhao Yizhen. He not only came to give lectures, but also received an 'honorary doctorate' and the title of 'honorary professor'.
Zhao Yi didn't care about doctors, professors, etc., but it would be nice to be given a title.
In his previous life, it was only a dream to get admitted to Shuimu University. Now he came here and became a doctor and professor. He felt very good, so he also prepared for the lecture.
Qiu Chengwen said that the content was a "complex screening method problem", so Zhao Yi prepared for the screening method.
He's very good at this.
Chen Jingrun proved Goldbach's conjecture of '1+1=2' by using the most basic sieve method. He applied the sieve method to the extreme and proved Goldbach's conjecture to the extreme.
The sieving method is very simple at first, which is to list the numbers one by one, and 'sieve out' the multiples of the previous numbers. The remaining ones are naturally prime numbers. However, the later it gets, the more complicated it becomes. The problem of expression is the key.
The main core of what Zhao Yi talked about was the expression of the screening method.
In the conference hall of more than 400 people, he patiently spoke step by step, "We can see that the initial expression is very simple, but later on we must use some means."
"The first thing is to add limits..."
There is no need to think about the process that Zhao Yi explains, it is a step-by-step detailed demonstration. Many steps do not require calculation, and the results can be obtained directly. The demonstration on the whiteboard is very clear, which makes people feel refreshing.
This is really not difficult for him.
What Zhao Yi is best at is the 'accumulation' mathematical method. The method is very simple and becomes difficult after superposition. However, because the basic method is very simple, the "Law of Cause and Effect" and "Contact Rate" do not require energy consumption. , it almost came out as soon as I thought about it, and then I listed the process clearly, and it naturally felt very clear.
Off stage.
The people sitting in the first two rows were all big guys from Shuimu University. Qiu Chengwen was sitting in the middle. Taking advantage of the opportunity, he turned his head and sighed, "I couldn't have said it better. It's Zhao Yi who deserves it." !”
"Yes, that's great!"
"It's hard to imagine that he is only in his early twenties. He is probably the youngest here, younger than the students."
second row.
Yan Zhixing, the only Chinese winner of the Turing Award and the founder of the Shuimu Yan Class, looked at Zhao Yi on the stage and felt quite emotional. He remembered that three years ago, the Admissions Office of Shuimu University asked him if he He wanted Zhao Yi to enter his 'strict class', but he considered that Zhao Yi was 'too talented' and felt that he was a little unsure, so he did not express his opinion.
Later, when he learned that Zhao Yi had proved Kakutani's conjecture, he thought with some fear, "It's a good thing he didn't come to my class!"
He still had some regrets at the time.
As long as they are engaged in education, everyone hopes that their students will have outstanding students. Genius is indeed difficult to grasp, but it is also a pity to miss a genius.
Now Yan Zhixing doesn't feel regret at all. He just feels very lucky. Otherwise, what should he do if he encounters the current situation?
The students are on stage and the teacher is off stage?
"I don't know what the mood of those who gave lectures to Zhao Yi at Yanhua University was like..." Yan Zhixing suddenly admired the teachers at Yanhua University for daring to give lectures to Zhao Yi.
How do you say this?
Now Zhao Yi is standing on the stage and his lectures are better than his. It is rumored that he is Zhao Yi's teacher. People will probably look at him strangely and ask in confusion, "What did you teach Zhao Yi?"
"I really can't think of it!"
In the emotion of many people, Zhao Yi completed the lecture easily and received enthusiastic applause at the end.
Everyone thought Zhao Yi spoke very well.
Some students who couldn't keep up with the thinking felt that they had learned a lot and couldn't help but applaud Zhao Yi.
Under the applause, Zhao Yi walked off the stage and was arranged to rest in the back. Then everyone from Shuimu University arrived. After a good chat, he followed Qiu Chengwen to the Mathematical Science Center.
The Mathematical Science Center of Shuimu University has been established, and scientific research and teaching have developed. Qiu Chengwen has a large office, and several mathematics professors have come together.
Zhao Yi started asking questions on the way. He wanted to know some cosmology and the contents of Einstein's equations.
Einstein's gravity field equation is used to describe that "gravity is caused by the curvature of space and time produced by matter and energy." It is directly related to Zhao Yi's addition of gravity elements to the boundary theory of particles.
Zhao Yi hopes to find some inspiration.
