Chapter 226 You Need Oxygen To Do The Questions
Half past two in the morning.
Song He woke up, lifted the quilt and sat in front of the computer.
There were more than a dozen mathematics papers opened on the computer at the same time. Although Song He scored 140 in English, there were still many blind spots when reading English papers, so he had to use translation software.
Fortunately, Professor Wang's memory is reliable. As the papers were searched one by one, Song He gradually found the answers to some questions.
Unfortunately, the scope given by Professor Wang was too huge. The mathematicians he mentioned had more than one book per person and numerous papers. Song He had to filter the papers based on their titles, but he was still forced to read many unrelated papers that were too difficult.
My head hurts so much, my brain is going to explode!

[Progress in mathematics detected, raised from gold level 68 to gold level 69! 】
The dizziness from lack of oxygen struck again, and Song He rubbed his temples painfully.
After a moment, he slapped his thigh suddenly.
Since I often suffer from lack of oxygen when doing questions, why not buy some oxygen? !
I took out my mobile phone and searched for canned oxygen. The takeaway app actually delivered it. There was a 24-hour pharmacy that sold 1 liter canned oxygen. I decisively ordered a large box of 36 bottles!
Song He picked up a piece of exercise paper, left the dormitory, and read it while walking.
Wandering to the school gate, it was three o'clock in the morning.
The delivery boy came swaying on an e-donkey, and Song He waved to him.
"Brother, why did you buy so much oxygen in the middle of the night?" The delivery boy was worried. He stopped the electric donkey and unloaded a large box. "Is there any student who has difficulty breathing? You need to go to the hospital! This kind of oxygen is used for mountain climbing. of!"
"It's true that I have difficulty breathing, but it's not a disease. I just did the questions." Song He explained with a smile.
"Did you do the questions?" The delivery boy was confused by the answer.
"It's not normal to do math problems all night without lack of oxygen!" Song He picked up the box and turned to leave. "It's not easy for me to run around in the middle of the night. I'll reward you later!"
The delivery boy was stunned for two seconds and said, "You guys have it harder than me! You need to breathe oxygen to do math problems in the middle of the night!"
Back in the dormitory, Song He kept his promise and gave him a reward of 100 yuan. He opened the box with scissors and took out a can of oxygen.
Pull off the plastic cap of the oxygen tank and insert it upside down on the nozzle to become a simple breathing mouth.
Song He held the oxygen tank tightly in one hand and slapped it on his face, while holding the mouse in one hand to search for papers, he continued to study selflessly.
After reading two long papers in a row, I felt a sense of hypoxia!
"Tsk! Tsk!"
Spray oxygen on your nose, inhale Song He, and your dizziness is instantly relieved!
Wonderful! I should have bought this a long time ago!
"Tsk! Tsk!"
"Tsk tsk tsk!"
With sufficient oxygen supply, the brain turns on performance mode!
Song He felt comfortable entering into a state of deep thinking, and his hand speed of turning over papers became faster and faster!
Reading mathematics papers immersively gives you the illusion of talking with mathematicians throughout the ages by candlelight.
Some mathematicians' bodies have long since rotted into mud, but the papers they left behind during their lifetimes are still brilliant. Song He could almost hallucinate a ghost figure of a mathematician standing in front of him explaining the topic. It might be a bit scary to think like this in the middle of the night. But there is indeed a sense of excitement coming face to face with a math giant!
After reading most of the papers, Song He was happy and then disappointed.
I am happy that I have mastered some new knowledge and my mathematical foundation has become stronger.
I am disappointed that the new knowledge has nothing to do with the program of the space window cleaner and cannot be used to improve the performance of the window cleaner at all.
At five o'clock in the morning, the repeated disappointment finally stopped!
Song He's eyes lit up, and his body leaned forward involuntarily, staring at the paper on the screen.
This paper is about the Calabi Conjecture.
Let M be a compact Keller manifold, then for any (1,1) form R in the first Chen class, there is a unique Keller metric, and its Ricci form is exactly R.
The paper clearly points out at the beginning that the key to Calabi’s conjecture is, in a vacuum without matter, can space be both curved and flat at the same time?
After reading a few paragraphs of the paper, which was very esoteric and obscure, Song He understood that his level was not enough to understand it yet.
But he has a strong intuition that the relevant knowledge in this paper may be the key to the qualitative change of the space window cleaner program!
Intuition is a mathematician’s most valuable weapon!
"Chi chi chi!" Song He sprayed oxygen several times. When the can in his hand was used up, he quickly opened the other can and continued to breathe oxygen.
He calmly solved the paper word for word and looked for other papers to read when he encountered any doubts.
At this moment, Song He is like a persistent gamer, moving forward steadily. When he encounters a big monster that he can't beat, he goes out to search for the master's strategy, then turns back and kills the big monster persistently, walking firmly on the blood of all the big monsters. go ahead!
The sound of oxygen being sprayed echoed in the dormitory. Cans of oxygen were used up one after another. Song He gradually cleared up some ideas.
Let’s start with the Einstein field equation. In the traditional equation without the cosmological constant term, the Ricci curvature tensor minus one-half of the Ricci scalar multiplied by the space-time metric tensor is equal to the energy momentum tensor of matter multiplied by G. related constants.
The latter is zero under vacuum conditions, so the Ricci curvature tensor is zero, becoming a Ricci flat space!
Flat space-time satisfies the Ricci flat space. The paper mentioned the example of Minkovsky space. Song He had never heard of it. After hesitating for a moment, he decided to take it.
Not only do you need to clear the level, you also need to collect them all and kill all the wild monsters!
Next is the critical Schwarzschild space, which is even more difficult. Like a BOSS with a long health bar, Song He desperately sucked in oxygen and fought with sweat all over his body.
Schwarzschild, I will fight with you!
Before I knew it, it was dawn outside the window.
Song He was dizzy, and he could no longer tell whether it was due to lack of oxygen, inebriation, or simply because too many brain cells had died in a short period of time.
But fortunately, he succeeded. The huge corpse in Schwarzschild's space fell down, and amidst the overwhelming smell of corpses, Song He sorted out more clues.
The main problem that Schwarzschild solved was the spherically symmetric analytical solution of Einstein's equations in vacuum.
According to the Schwarzschild metric, not all Ricci flat spaces are straight spaces!
For example, a massive celestial body can distort nearby space-time to form Schwarzschild space. The most important thing is that the massive celestial body does not need to be in Schwarzschild space!
Song He thought about it for a long time and thought to himself, isn't this just a fucking black hole?
After reading a few more papers, it turns out that Schwarzschild's theory can be used to deal with black holes.
It seems that what the teachers said is true. Mathematics and physics are connected, and people who are good at mathematics are often good at physics.
Song He had just thought of this when a system prompt appeared in front of his eyes.

Song He smiled and said whatever he wanted.
After using up another bottle of oxygen, he threw it on the ground, took out a new bottle of oxygen from the box, and continued to breathe.
He was thankful that he had placed an order for oxygen at night. There was no oxygen supply. After studying these contents intensively, he was afraid that he would have to pass!
However, we have just learned the beginning of the paper. The next paragraph of the paper cuts into Qiu Chengtong's thinking. Is it possible that the global space without energy and momentum is curved?
Song He was ready, and Calabi's conjecture was proved by Mr. Qiu. His thinking was more important than anything else.
"Dong dong dong!" The room door suddenly knocked.
"Please come in!" Song He said.
Shekov, dressed in fiery red, opened the door. The next second he saw the scene in the room clearly, his face was shocked, and his jaw almost dropped to the floor!
Song He was sitting at the table. The ground around the chair was full of oxygen tanks, scattered like a bunch of bombs!
In Shekov's momentary trance, Song He became an artilleryman. Surrounded by piles of shell skins left after firing, a murderous aura rushed towards his face!
