My technology affects the whole world

Because Ma Tian read too fast, others also unknowingly speeded up their reading.

Another hour later, other people finally expressed their views one after another that they had finished watching.

Bekier Cobb paused his voice and said, If you have any questions, you can ask them.

He was already prepared for Ma Tian and Halls to use materials to attack Musk. Similarly, they have also made preparations to attack Hua Shuwen's materials.

The main problem here is that Yingjiang and Rabbit are not willing to deal with it. Naturally, people from other countries will not speak first.

Ma Tian saw that the audience was silent, but he was the first to speak: I found some problems with Musk's materials.

As soon as he spoke, everyone in the audience looked over, and Halls raised the corners of his face and mouth, ready to watch the show.

I found three problems here:

First, there is a deviation in the calculation of satellite orbit coordinates. Although I did not look at all the thousands of satellite coordinates Musk applied for in the second phase of materials because of limited time, I could tell at a glance that there was something wrong with the 112th, 116th, and 134th satellite coordinates.

I scanned about 200 coordinates, and based on probability, at least 90 of the data Musk applied for this time were wrong...

It's impossible. We have rigorously calculated this data coordinate.

When he heard that there were 90 errors, Bekier Cobb couldn't help but interrupt. Aerospace and aviation cannot tolerate such a high error rate. He also didn't believe that his countrymen were so low-level and made such outrageous mistakes.

Listen to what I have to say before you speak. When I finish speaking, I will naturally verify them one by one. Ma Tian refuted mercilessly. As the chairman of the alliance, Bekier Cobb interrupts others when they are speaking. Don’t you even know it’s rude?

Bekir Cobb looked ugly, but he still shut up. Ma Tian continued:

Second, the experimental data is too ideal. He specified in the launch parameters that the Starlink satellite will operate in a phased manner in a low-Earth orbit at an altitude of 550 kilometers. This model is too ideal and does not take many factors into consideration. I seriously doubt that this model is Made by a guy who failed math...

As soon as Ma Tian opened his mouth, he explained in detail the three problems he had discovered. Although Ma Tian tried his best not to curse, but when he saw some mistakes, he would still be like a teacher who saw a student write a bunch of Xiang. With sternness and sarcasm.

This means that Musk was not present at the scene. He must have put on a stinky face and exchanged insults with Ma Tian.

Bekir Cobb also had an ugly face as he listened to Ma Tian continue talking. From his position, he naturally suspected that Ma Tian was forcefully finding mistakes and talking nonsense.

He wanted to see what arguments Ma Tian came up with later.

Naturally, Ma Tian would not disappoint him. After he finished speaking the three questions, Ma Tian began to demonstrate on the spot.

For the first coordinate problem, let's look directly at the derivation of the formula. Although Musk's material omits this step, based on the results, I can probably reverse his formula:

N0 = GM^1/2 A^2/3

N = N0 +^N

…

Ma Tian's eyes became serious. As the most powerful brain modified by the system, he began to list Musk's formulas step by step on the shared screen.

Bekier Cobb, Halls and others' eyes widened immediately. They were not bad at mathematics, which did not prevent them from being shocked that Ma Tian could list those very complicated formulas one by one.

Damn it, you have to know that this is a formula with one mathematical ring within another, there are quite a lot of them!

Moreover, Ma Tian deduces backwards. During the derivation process, complex numbers can be substituted into formulas in seconds. What kind of mental arithmetic ability is this?

If they hadn't known that Ma Tian had seen these materials for the first time, they would have suspected that Ma Tian had read the materials in advance and made preparations.

Not to mention them, even Zhai Xizhong, a domestic boss who was familiar with Ma Tian, ​​his eyes widened.

He had seen in the files that Ma Tianneng had a photographic memory and a super memory, but he didn't tell him that Ma Tianneng could make such unreasonable deductions. This not only required being very familiar with these formulas or fields, but also having super strength. mathematical sensitivity and logical reasoning ability.

Ma Tian eloquently listed more than 50 formulas, and began to bring Musk's satellite coordinate data into the demonstration on the spot, and then the first data was successfully certified!

Bekir Cobb had to interrupt and said: Mr. Ma Tian, ​​wait a minute, I will try to use your formula to plug in the data.

Ma Tian acted too fast, he had to verify it himself before he believed it.

Hearing this, Ma Tian just nodded without refusing, he was so confident.

Bekier Cobb began to copy formulas and calculations, and others were also idle, such as Halls and Honda Nanosuke began to calculate on their own.

Half an hour later, Bekier Cobb looked at Ma Tian's formula in despair and collapsed in his seat.

Honda Nanosuke from the island country also twitched his beard, showing his great shock.

All he needed was the curse Baga.

Only Halls might have a better reaction. He just looked at Ma Tian in shock. He didn't expect that there was such a person in the world.

If he hadn't seen it with his own eyes, he would never have believed it.

Bekier Cobb went to Musk without believing anything and sent Ma Tian's formula to them, asking them to confirm it quickly.

How's it going? Is there any problem? Ma Tian calmly took a sip of tea and asked.

The atmosphere was very silent. Everyone in the Eagle Camp looked at Bekiel Cobb and asked him to speak.

Mr. Ma Tian, ​​I'm going to go to Musk to make sure. I'll just assume you're right and go on. Bekier Cobb said.

Okay, since I think these formulas are correct, then I will find errors based on these formulas!

You can see the 8th formula I listed on the screen. At first glance, it is just a simple satellite orbit formula, using the evolution formula written by Kepler's law.

But the formula here obviously does not consider the impact of the moon's movement here on the satellite's gravity. Even if the moon moves behind the earth at this time, Musk should also take the moon's influence into consideration...

Mr. Ma Tian, ​​the influence of the moon should be negligible, right? After all, it is only 0.000001 times the acceleration of the earth. Bekier Cobb interjected.

Is the impact of 0.000001 times acceleration very small? Ma Tian retorted, 1 micron is 1,000 times 1 nanometer. Whether the impact is small or not must be fully considered. For example, if Musk continues to deduce formulas like this, the following 47 formulas will be There will be a certain deviation due to the influence of this formula data.

The most obvious one is the deviation of the low-orbit satellites launched near the equator. The diameter of the earth is considered here, so I said there is a problem with the coordinates of the 112th, 116th, and 134th satellites. Those satellites were launched into orbits above the equator. The accurate data should be yes

GEOGCS[WGS 84,DATUM[WGS_1984,SPHEROID[WGS 84,6378137,298.257223563,AUTHORITY[EPSG,7030]],AUTHORITY[EPSG,6326]],PRIMEM[ Greenwich,0,AUTHORITY[EPSG,8901]],UNIT[degree,0.0174532925199433,AUTHORITY[EPSG,9122]],AUTHORITY[EPSG,4326]]… …”

(These coordinates are not made up by the author, but are the real WGS84 coordinate system, described by OGT WKT. This is generally the coordinate system used by Google, while Goosechang and Bade Maps use the GCJ02 coordinate system, but it is basically this complicated. )

Ma Tian dictated the three complex coordinate systems. If Tianji hadn't thoughtfully used subtitles to display them, a group of foreigners might not have been able to remember such long data.

Zhai Xizhong looked at the subtitles with bright eyes. He suddenly felt that Ma Tian had made this subtitle function so advanced. It could translate in real time and it was a very powerful translation software.

Bekir Cobb found that his brain was running out. Why did he feel like he was listening to a professor's lectures in college? He felt a little struggling to keep up. How could Ma Tian pick up such complicated numbers at will? He was definitely not talking nonsense. Of?

He could only take notes like he did when he was a student, preparing to tell Musk this and let him verify it.

Thinking of this, he felt a little happier. If Ma Tian was right, they could avoid the failure of their satellite launch in advance and save costs.

Would Ma Tian be so kind? of course not!

After talking about the satellite coordinate data, Ma Tian looked at the people in the audience who were looking at him. He didn't bother to explain in detail and continued to talk about the problem:

Not only is the 8th formula wrong, but also the 23rd and 37th formulas. In my opinion, the engineer who wrote this formula was too careless. Can the ionospheric model equations be listed so simply... …

There is also this experimental data model. The model is based on an ideal situation, and the data obtained is also very ideal. Although there is no problem with the sky, the ability to withstand interference and accuracy will be greatly reduced, most likely due to some factors such as wind direction, Factors such as the ionosphere produce large deviations, leading to launch failure!

For example, here, if we add a 12-level wind speed interference of 32.4m/s to it, the angular power vector will start to become 3.782kg*m^2/s, and the corresponding moment of inertia will become 2.8913...

Ma Tian eloquently demonstrated the problem. When it came to the end, he asked Tianji to cut a small split screen for the scene and simply performed a simulation animation to demonstrate the data formula.

This operation made other people's pupils shrink, and they stared at the demonstration video on the computer screen. They didn't know how Ma Tian did it, and what kind of modeling demonstration technology was used.

They vaguely guessed that it was related to artificial intelligence, but they did not dare to delve deeper into it. After all, they were not experts in this field, and the level of intelligence was a bit shocking, far from the artificial intelligence they usually knew.

The entire meeting turned into Ma Tian's personal show. The 11 main professional members of the Telecommunications Alliance were all listening carefully in front of the computer screen like students. As for whether they understood or not, you had to ask them.

Anyway, Bekir Cobb would never admit that he couldn't understand it later. He was a senior professor from MIT with a doctorate degree in mathematics and physics. He could still understand what Ma Tian said, but Ma Tian He was speaking in Chinese and it was difficult for him to understand.

While Bekir Cobb was looking for a reason, Musk's chat profile picture also started to flash, and there was a message.

He couldn't help but take a break and read Musk's news on another computer:

[Musk: Mr. Cobb, where did you obtain our experimental formula? The end result of these formulas is exactly the same as ours, except some are simpler! 】

Seeing Musk's news, Bekier Cobb's pupils couldn't help but shrink. He took a deep look at Ma Tian who was still talking about the problem. For the first time, he felt incredible about a person.

Is there really such a powerful person in the world?

These are the three main problems I found. Of course, there are also some minor problems that I am too lazy to describe. All in all, in my opinion, Musk's materials cannot pass the test at all. I don't know how you passed it?

Ma Tian spoke for more than an hour before concluding with the last sentence. The last rhetorical question can be said to be a slap in the face to Bekier Cobb.

After finishing speaking, Ma Tian also looked at Bekir Cobb. However, Bekir Cobb did not become angry as he expected. Instead, he sat in his seat a little confused. Seeing that Ma Tian had finished speaking, he also After coming back to his senses, he asked in confusion: Is the lecture finished?

Ma Tian took a sip of tea for himself, and soon realized that Bekir Cobb was simply wandering in his mind just now. It was very similar to him who was a gangster in his previous life and listened to the professor's Mathematical Physics Methods course. On the surface, he was serious. While listening to the lecture, I was secretly thinking about whether to have braised chicken or cross-bridge rice noodles for lunch.

Yes, I've finished speaking. I believe Mr. Cobb you have understood the three questions I just said. Do you still think Musk's materials can pass the review? Ma Tian organized the speech and said, he will not give Ma Tian There may be no one present except Zhai Xizhong to save face.

Uh... Bekier Cobb was silent. He didn't know what to say. Ma Tian almost showed off his face, which made him a little bit unable to get off the stage. He couldn't admit in front of everyone that he passed hastily.

And even if it's wrong, Musk must be right from his standpoint.

Mr. Ma Tian, ​​this matter has been approved, and the Telecommunications Union has not withdrawn the precedent of the review at that time! Bekier Cobb said expressionlessly.

Then you just saw a mistake and let him continue? Ma Tian asked, not letting go of the topic.

I'll pass your comments on to them to double check!

Bekir Cobb has made up his mind to insist that Musk's materials pass review. This shameless look also made Ma Tiandu stunned.

He has rarely experienced such things, and he never expected that there would be such a shameless person.

After all, it was because he had seen less of the world. He was usually spoiled by Wang Chenbo, Hua Shuwen and other big bosses, and he had never experienced such nastiness.

So it's just a quick inspection to make up for it? What if I didn't come to the meeting this time? Ma Tian's face also turned cold. The International Telecommunications Union had to admit that it still played a lot of positive roles in the development of telecommunications on the earth. , including domain name specifications for local area networks, Internet security, etc.

But if it has become Yingjiang's interest group now, then don't blame him for denying it.

When Bekir Cobb was questioned by Ma Tian, ​​his face completely fell. He never expected that Ma Tian would be so unreasonable and not give him face.

Then what do you want? His voice also turned cold.

“Musk’s application materials must be sent back for re-examination, and all the satellite coordinates set in his materials will not count!”

The meeting suddenly started to be filled with the smell of gunpowder, and the point of contact was tense!
