Chapter 173 To the Brilliant People (Part 2)(5.6K)
More than a week ago.
After deciding to build the aircraft.
Xiao Zhao quickly fulfilled his promise:
While preparing various types of ore materials, a large team was also quickly organized.
The total number of people in this team is just over 700, and about half are craftsmen, totaling more than 300 people.
Among them, the top Jigong is except Siegfried.
There are also three top-notch craftsmen from various places, who are the "eighth-level craftsmen" of the Song Dynasty.
This ratio is actually quite normal.
Take 1959 as an example.
At that time, there were more than 70 million skilled workers in the country, including more than 1,300 eighth-level workers recorded by the Ministry of Machinery.
The first generation submarine, the first missile, the first atomic bomb, and the first space satellite are all inseparable from the hard work of the eighth-level workers.
The current population of the Song Dynasty is about 100 million. Although the number of workers engaged in handicrafts is not as large as that of later generations, it is still normal to produce three or five talented people with eighth-level workers.
After all, the key to level eight workers is manual ability, which is definitely related to mechanical and technological foundations, but it is not particularly close.
For example, tired silk, such as diancui, the difficulty is no lower than the requirements for eighth-level workers.
According to Xu Yun's plan.
in the second half of the entire production process.
These craftsmen will take on important mold casting tasks, which directly determines the finished product rate of the aircraft.
And in addition to the craftsman module.
The remaining half of the team members were all recruited by Xiao Zhao...
Numeracy expert.
As said before.
Scientific research will never be a one-person affair.
Because of his experience in his previous life, Xu Yun could rely on himself - or in other words, he could only design the engine parameters on his own.
Because in this era, apart from him, no one else has the ability to design engines.
But in addition to engine design, many data calculations must rely on the assistance of others.
This batch of calculation teams was recruited from all over the country, and the leaders were mainly Lao Jia.
At the same time, Han Gonglian, Liu Yi and others also held middle and senior positions in the team.
Although they also do not have the knowledge base related to engines and fluids, their computing power is at the top in this era.
In some cases, Xu Yun only needs to give conditions and equations.
Even if the concept is a bit out of scope, a team of dozens or more people can still come up with results after calculations.
After all, in the three or four months between the death of the Empress Dowager and the coup, Xu Yun instilled a lot of fresh knowledge into Lao Jia and others, and even involved some - note that it was partial calculus knowledge.
This calculation team was also placed in the Instrument Manufacturing Bureau, and Xiao Zhao planned a huge courtyard for them.
When Xu Yun came to the entrance of the courtyard, the courtyard was very lively:
Perhaps due to the limited space, it was already dark at this time, but there were still a large number of tables placed in the courtyard, where hundreds of people were doing mathematical calculations.
Some of them calculate data silently alone.
There are also those who work together in pairs and groups.
Others seemed to have encountered some problems and were gathering in a corner to discuss quietly.
For example, on the side near the entrance, there were seven or eight mathematicians who looked like scribes communicating with each other.
Seeing this, Xu Yun walked up to a few people and listened with interest.
The first person to speak was a middle-aged man in yellow clothes. He pointed at the two pieces of math paper on the table and said:
"Brother Ou, the thickness of the valve plate is one hundredth of an inch, the cross section of the nozzle is set to Tianyuan, and the volume has been determined, but why are the results calculated by you and me different?"
Another thin, dark man heard this and stretched out his finger to draw a horizontal line on a certain column:
"Brother Zou, it seems to me that you have miscalculated the value called 'axial force'."
"The prefix should be one-third, not one-quarter..."
The scribe named Zou in yellow clothes shook his head and said:
"No, no, I followed the curved gradient equation taught by Mr. Tongyu. The value must be one quarter. You were wrong..."
Xu Yun listened for a while and almost understood the problem these scribes were struggling with:
Simply put, this is a calculation of thrust per unit section under the definition of the same thrust-to-drag ratio.
It involves the thickness of the valve plate and the cross section of the nozzle, as well as the issues of reflection and sound speed.
When I was organizing a math team.
Considering some conceptual issues, Xu Yun and Lao Jia specially produced an instruction manual.
The manual defines some superdimensional concepts, such as the gravitational constant is 6.67259×10N·m2/kg2, the speed of light is 300,000 kilometers per second, etc.
That is to say, you don't care where the number comes from, just use this number and report the answer in the end.
The instruction manual is like an instruction manual. Ordinary mathematicians can directly calculate whatever data they are assigned through the relevant formulas.
However, although the formula is fixed, in some situations it is difficult to determine which entry to use.
Therefore, it is not surprising that some controversy arises.
The arguments between the two seemed reasonable, and the few scribes around them seemed a little uncertain.
Just when neither of them was convinced by the other.
The thin, dark scholar named Ou suddenly noticed Xu Yun eating melon.
At this time, Xu Yun was wearing regular clothes. The scribe surnamed Ou thought that he was also a member of the calculation team and asked:
"Brother, what do you have in mind?"
"I?"
Xu Yun was stunned for a moment. After confirming that the other party was asking him, he remained silent for a moment and said in deep thought:
"I dare not take it seriously, but I can barely judge whether the direction of solving the problem is right or wrong."
The scribes surnamed Ou and scribes surnamed Zou looked at each other and did not look down on Xu Yun because of his age. After all, those who could come to this courtyard were novices:
"The direction of solving the problem? Brother, please elaborate on it."
Xu Yun thought for a while, then stretched out his hand to draw the shape of a combustion chamber:
"According to the design drawings of the engine, we can know that the feed inlet and interface are horizontal."
"It can be seen that the temperature in the combustion chamber must be different, that is, the temperature in the area near the fire is higher than that in front of the front pressure wave."
"According to the 39 formulas in the manual, we know that pressure waves are a type of sound wave, and the speed of sound has a functional relationship with temperature."
"Therefore, when the cross-section rebounds, the back wave will inevitably catch up with the front wave, and we can only use the gradient of the curve to start."
After saying this, Xu Yun couldn't help but look at the scribe named Zou:
"So I dare not say that Brother Zou's data has no calculation errors, but at least I can be sure that his thinking is correct."
"If you repeat the calculation several times, you will be able to get an accurate value."
Bang bang bang——
As soon as Xu Yun finished speaking, a round of applause suddenly sounded from the side.
Xu Yun looked around and saw that at some point, Liu Yi had quietly come to his side.
I saw Liu Yi clapping and laughing:
"Young Master Wang has a clear mind, he hits the point in his words, and his words are concise and clear. Liu is really impressed by him."
Seeing Liu Yi appear, several scribes quickly straightened their expressions and said respectfully:
"Hello, team leader."
Xu Yun also bowed his hands:
"Mr. Jinqu, long time no see."
Liu Yi returned the greetings to everyone in turn, pointed at Xu Yun and said to everyone:
"I'm afraid some of my colleagues don't know something. This is the well-known '30,000 Updates a Day' Wang Xiaochun, Mr. Wen Huanong."
"The "Standard Manual" that these few people have been studying day and night was written by Mr. Coder and Mr. Tongyu."
Hearing Liu Yi's introduction, the scholar surnamed Ou was suddenly surprised and stood in awe:
"It turns out that he is Mr. 30,000 coders a day. Xiao Ke has admired his name for a long time. I'm rude. I'm rude."
Xu Yun also bowed his hands towards him, his expression looking very calm.
Again.
It’s Wang Lin who makes 30,000 updates a day. What does it have to do with him, Xu Yun?
Then he said goodbye to everyone and wandered around the courtyard with Liu Yi.
"Mr. Jinqu."
Looking at the scribes in the courtyard who were lighting candles and calculating data, Xu Yun took the initiative and asked:
"Is everything going well these days?"
Liu Yi nodded, pointed to an area where the most mathematicians gathered, and said with a smile:
"Everything is going quite smoothly. The team members come from all over the world. They are either low-level officials with no ambitions, ordinary elementary school students, and some are hermits living in the mountains and forests."
"If it hadn't been for His Majesty's grace, it would be difficult for any of us to see such a grand sight in this life, so naturally we would cherish it very much."
"Now we have calculated and verified more than 50 sets of data, and on average we can produce seven sets a day, which is much higher than the expected five sets."
Liu Yi's expression was a little emotional, and what he said was true from the bottom of his heart.
Although there were many well-known mathematicians in ancient China, not many could truly leave their names in history.
Except for a few cases.
Most numeracy scholars are just ordinary petty officials or ordinary teachers in elementary school.
Even Lao Jia, who counted everyone at that time, can only leave an unknown record in the history books, let alone other ordinary people.
Therefore, after learning that the emperor... or to be precise, the imperial court had requested a request, and that there would be a high subsidy.
Almost all the mathematicians who received the letters accepted the recruitment.
to some extent.
This kind of concentration of mathematicians on calculations has never been seen in history, let alone the Song Dynasty.
Therefore, when Liu Yi called it a grand scene, he did mean it sincerely.
Then Xu Yun thought for a while and asked:
"Mr. Jinqu, where is Mr. Tongyu?"
The night was a little dark at this time. Liu Yi looked around, then pointed to a secluded cabin in the corner and said:
"Mr. Tongyu is in that room. Mr. Wang, let's go over and have a look?"
Xu Yun nodded:
"It's time to work."
Then, under the leadership of Liu Yi, the two quickly arrived at the door of this room.
However, Xu Yun did not rush to knock on the door, but came to the window and looked inside through the carefully placed glass window.
As soon as he saw the situation in the house clearly, he was a little stunned:
At this moment, this room with an area of almost 40 square meters was filled with stacks of calculation papers.
The arithmetic paper is partially packaged and placed in a corner.
Some were scattered messily on the ground.
On the only two tables in the room, Lao Jia and Han Gonglian were sitting respectively, both bowing their heads and calculating something.
From time to time they would yawn and rub their eyes, but soon resumed their work.
From the mental state, it can be easily judged that the energy consumed by these two people is much higher than that of ordinary arithmeticians.
Seeing this, Xu Yun couldn't help but look at Liu Yi and asked:
"Mr. Jinqu, is this...?"
After hearing this, Liu Yi was silent for a moment, sighed quietly, and said:
"Master Wang, although the manual written by you and Mr. Tongyu is good, it is a dead thing after all."
"As you saw earlier, there are situations where differences of opinion are bound to arise in practice."
"So Mr. Tongyu came up with a method to assign each task to three groups for calculation. Each group will first conduct calculation discussions to determine a unified value to report."
"If the numbers reported by the three groups are the same, they will be temporarily summarized and await practical verification by Master Qi."
"But if any of the three groups has different results, it will be handed over to Mr. Tongyu and Mr. Yang Huai, who will be responsible for re-inspection."
"Admittedly, this approach is bound to have some mistakes, but this is the best we can do."
Xu Yun was silent when he heard this.
after awhile.
He looked at Liu Yi thoughtfully, especially the bags under his eyes for a few seconds, and a flash of realization flashed in his heart:
"Mr. Jinqu, I'm afraid you are also one of the people responsible for the re-inspection, right?"
A smile appeared at the corner of Liu Yi's mouth and he said:
"There is no way. The six math scribes like us who attended the lecture in Su Mansion are now the only six people who can do the retest."
"Mr. Wang, did you know that Mr. Tongyu had left a suicide note on the day the team was formed?"
"Mr. Huaiyang had a baby at home yesterday, and he never asked for leave to come home."
Then he turned around and looked at the face illuminated by the candle on the piece of paper in the courtyard:
"Mr. Wang, in fact, it's not just the six of us. The entire team has a total of 313 mathematicians. Maybe some people have made mistakes due to ability issues, but no one is slacking off."
"We all know the truth. Who is not tired? Who wants to be tired? But that is flying!
"For every one ten thousandth of a value we calculate, we may be able to lift the plane one foot higher."
"For thousands of years in China, since the Yan and Huang generations, no one has been able to conquer the sky, but now, we have the opportunity to do it."
As he spoke, Liu Yi looked at Xu Yun again, with brilliance flashing in his eyes:
"Your Majesty, Mr. Su once told us privately that your talents are unparalleled in ancient and modern times and are rarely seen in the world. If you say you can, then you really can."
"We may not be able to catch up with you, but we can push you as much as we can."
“We don’t seek to leave a name in history, but we seek to witness with our own eyes the great Chinese people’s first journey to heaven in thousands of years. Just as Mr. Tongyu said when he wrote his suicide note, he will die without regrets.
!”
After Xu Yun listened quietly to Liu Yi's words, a special emotion surged in his mind.
He wanted to tell Liu Yi.
In fact, I am just a time traveler from later generations, and all I have is relatively complete knowledge from later generations.
The truly great and great thing is not me, but you great sages...
In later generations, we not only conquered the sky, but also touched the universe. The Mozi satellite and the Zhurong Mars rover are all tributes and tributes to our ancestors.
Thinking of this, he couldn't help but look at the sky
There is not a single dark cloud in the starry sky tonight.
The bright moon hangs high and the stars shine brightly.
But in Xu Yun's view.
The starlight tonight is not in the sky, but in this human world.
December 8, 1100 AD.
There is no snow, but it is the time when the stars of China shine.
