The Tang Dynasty started from saving Empress Changsun

Scientific research is easier said than done, especially when it requires the cooperation of many people.

Originally, Chen Jingke imagined that everyone would carry out the research in groups, and each group would be responsible for the research of a component, which was done in many works before.

For example, when building steam engines and water pumps, this method was used, and he thought it should be similar this time.

Then when you actually operate, you will know how naive it is.

Scientific research and production according to drawings are two completely different concepts.

Production according to the drawings, data standards and so on are ready-made, and everyone can follow the standards.

Scientific research is from zero to some, even though he has pointed out the direction and provided some drawings, it is still difficult.

Without a scientific and systematic plan, without a strong coordinating organization, without a strong leader as the team leader... Grouping will only make everything more chaotic.

Everyone worked enthusiastically for several days, only to find out that they had done a lot of things and failed to achieve any results, which hit them hard.

Chen Jingke was very happy, and said: "Everyone, now you know the difference between producing according to drawings and doing research from scratch?"

"Don't be depressed, on the contrary, this is something to be happy about. Recognize the difference between the two, face up to our shortcomings and correct them, so that we can improve."

Everyone's mood has improved a lot.

Li Tai asked, "Have you thought of a solution?"

Chen Jingke said: "I have a preliminary idea, but I still need to try it to know if it will work."

Cheng Huailiang said: "Then what are you waiting for, arrange it quickly, don't care if it works or not, let's try first."

Others also said one after another: "Yes, try first and then talk."

Chen Jingke waved his hands to calm everyone down, and then said, "Okay, everyone, listen to me."

"The original grouping remains the same, but this time each group selects one with the best skills as the team leader, and then elects a more clever one as the deputy team leader."

"Another team of general technical consultants will be set up, and the team leader of each team will serve as a team member. I will be more arrogant and take the position of team leader, and Wei Wang will be the deputy team leader."

"The job of the technical team is to gather the strength of everyone to formulate various plans for watch research, and then split the plans to each group..."

"When I get off work every day, the team leaders gather together to exchange experiences, determine their own research progress, etc..."

Naturally, everyone had no objection to his arrangement. After some operations, each group re-elected the leader and deputy leader.

Then all the team leaders gathered together to conduct a technical demonstration on the production of the clock to ensure that everyone can understand what everyone is trying to make.

What are the technical requirements, where are the current problems, and what problems do you want to overcome.

After all the team leaders had a clear understanding of clocks, they formulated a research plan again, and then each team leader received the task.

At the same time, the team leaders made a plan within the group and explained it to the general technical consultant group, so that each group can know what the other is researching.

Only in this way did the groups begin to enter into specific research.

Chen Jingke didn't know if this method was right or not, he could only do it based on what he had heard in his previous life, plus his own imagination.

Then, in the process of work, we constantly sum up experience and improve it. I believe that one day we will be able to establish a set of truly scientific scientific research methods.

But no matter what, the method he came up with is indeed much stronger than everyone's headless flies.

In particular, the technical coordinating group has played a vital role.Various research works have been carried out rapidly, and considerable progress has been made.

For example, the model of the escapement was quickly created, and hanging the pendulum could indeed drive the gear to rotate.

Another group specialized in making springs, and quickly came up with qualified springs.Installed on the suspension point of the pendulum to provide driving force for the pendulum.

Only limited by the quality of the steel, the spring is not elastic enough, and it needs to be re-energized in about four or five days.

But in any case, the most basic power structure of the watch is completed, and the rest is minor adjustments.

For example, how to make the escapement rotate at a constant speed, how to determine the speed of the rotation speed... These all take time to explore slowly.

Originally, Chen Jingke thought it would be difficult, and he had to build a transmission gear structure, but a student named Zhao Youchang solved it with two nails.

Specifically, one nail is nailed on each side of the transmission rod of the escapement. No matter how much force is applied, the swing range of the transmission rod cannot exceed the constraint of the two nails.

The problem of uniform rotation of the escapement is thus solved.

Chen Jingke was also dumbfounded, and then began to self-reflect. He was still influenced by his previous life and couldn't help complicating the problem.

Inspired by Zhao Youchang, everyone seems to have awakened and proposed various methods.

Then someone discovered that the length of the pendulum can affect the speed of the rotational speed. After a series of experiments, the exact frequency of beating once a second was finally found.

Among them, Chen Jingke's watch played a big role. After all, it started from scratch, and no one could know exactly how long a second should be.

If it is measured purely by hand, it will take a long time and the error will be very large.

The earliest clock in the previous life, if the error of a day can be guaranteed to be within 15 minutes, it is considered a high-quality watch.

Later, with the research and conclusion of generations, the error of the mechanical watch was fixed within 1 minute per day.

Now with his watch as a reference, he can more intuitively measure whether the second hand is beating fast or slow.

Not only saves the time of groping, but also directly reduces the error of the clock to the minimum.

Of course, if you want to reduce the error to no more than 1 minute per day, it is not possible to do it simply by the structure, and the workmanship is equally important.

For his watch, everyone naturally expressed surprise, but he dismissed it by saying that only this one was made by the elders of the family.

Seeing this, everyone didn't dare to ask any more questions.

Li Tai was very calm. He had seen sports bracelets before, and it was not surprising that he had multiple watches.

Now there is only the last problem left, how to solve the problem of the different rotation speeds of the three hands of the hour, minute and second.

Fortunately, the team led by Li Tai made the differential gear under the prompt of Chen Jingke.

The combination of three gears of different sizes is a very simple and crude structure, but it perfectly solves this problem.

Assemble all the parts and the clock ticks away.

"Oh!!!" Everyone cheered in unison.

"Haha... made it, we made it."

The loud voice was heard by half of the people in the outer courtyard.

The outer courtyard is only this big in total, and everyone will soon know what happened.Chen Jingke is leading the Gewu class to make a timing tool, and everyone knows this.

You can tell it's a success by hearing their cheers.

He couldn't help but sigh in his heart, he really deserved to be Master Chen, he was smart.

Then what to do.

Chen Jingke is also very happy, partly because of the creation of clocks and watches, but also because this action has stimulated everyone's interests and established a set of scientific research processes that seem to be feasible for the time being.

As long as these things are formulated, even without his guidance, everyone will continue to create more good things.

The clock is finished, but the work is not over.

The next step is to make minor adjustments to the clock to ensure that it can run for a longer period of time without any problems, and to reduce the error as much as possible.

The most important is the statistical measurement of various parameters.

For example, where should the two nails that limit the swing of the escapement drive rod be nailed, what is the gear ratio of the three needles that control the hour, minute and second, the ratio of the length of the pendulum to the speed, and so on.

Only when the various parameters are determined can the clocks be mass-produced uniformly.Only other craftsmen can learn and use them flexibly to produce more styles of products.

In order to prevent the manufacturing process from affecting the accuracy of the parameters, they built several clocks and watches to measure at the same time, and finally determined a more accurate value.

At the same time, the entire production process of the clock is also determined.

Afterwards, of course, some celebrations are indispensable. Tianranju is my own home, and there are all kinds of food and wine.

Wu Shu also came to the celebration banquet, so she can naturally see the value of it, as clocks and watches are very rare.

It's just that she already knew about Chen Jingke's plan, so she could only withdraw her plan to start this business with some regrets.

The celebration banquet was over, and the two returned to the backyard together.

Wu Shu said with admiration: "You have created another amazing thing, and it is one step closer to your plan."

Chen Jingke smiled and said: "Yeah, it's so satisfying to be able to watch my plan come true step by step. By the way, I haven't asked you yet. Is there anything you want to do?"

Wu Shu was stunned for a moment, and said, "Me? I hope Zixiao Temple will become more and more prosperous, and I hope I can help you realize your wish as soon as possible."

Chen Jingke shook his head and said, "This can't be considered a wish, right? What else? For example, to become a poetess and a successful businesswoman."

"Just like Yihe wants to be a female scholar, and Yi Nu told me a few days ago that she wants to be a novelist. Don't you have something you are interested in and want to do?"

Wu Shu thought for a while and shook his head: "No. I didn't think about it when I was a child. After Yeye passed away, I just wanted to live a good life, and then I wanted to help you well and manage Zixiao Temple well."

Chen Jingke was about to say something more, but she smiled first: "Why do we have to have lofty goals and ideals? You said before that the greatest meaning of life is to live well."

"I try my best to make my life better and happier, and make our family more prosperous. Isn't that the greatest meaning?"

Instead, Chen Jingke was left speechless, so he could only say: "What you said is very reasonable. I judge others by myself. As long as you are happy, everything else is not that important."

Wu Shu said: "Yes, but I am already very happy that you care about my thoughts."

Chen Jingke's heart warmed, he took off the watch, grabbed her hand and put it on his wrist, saying: "This is one of the most precious items I brought from my hometown, and I give it to you."

As the bedside person, Wu Shu naturally knew about this watch, and Chen Jingke taught her how to use it, so she naturally knew the value of this watch.

Seeing him giving this watch to her at this time, infinite joy welled up deep in her heart.For the same reason, she also believed that this was Chen Jingke's final recognition of her.

She had known for a long time that Chen Jingke had sent Zhang Ping, Yuzhu, and Yi Nu all the things they brought from their hometown, and she had always cared about this matter in her heart.

The value of the item is not important, the important thing is the meaning.Whether others have her or not, do they have any opinion on her?
Now she finally has it, and all her previous doubts have disappeared.What's more, what was given to her was the most precious watch, which undoubtedly highlights the status of a big lady.

……

Next, Li Tai and others used copper, gold, silver, and sandalwood as materials to build a three-story loft-style clock.I also went to the palace to ask for a piece of plate glass, which was installed in front of the clock.

It took about a week before and after to create a beautiful and luxurious one-person tall grandfather clock.

Then Chen Jingke and Li Tai escorted the clock into the palace and dedicated it to the eldest grandson Wugou.

The reason why it was given to the queen instead of the emperor is very simple. They are all protected by the queen, so naturally they give priority to pleasing her.

The eldest grandson Wugou really liked this luxury clock, and looked around and looked at it.

Here Chen Jingke deliberately opened a window behind the clock and installed a small plate glass. Through this small window, people can clearly see how the machine works.

This kind of subtle effect is very good. When a person often looks at the mechanical movement and finds the beauty in it, he can't help but pay attention to science and engineering.

Sure enough, Changsun Wugou liked it very much, and stood behind and watched it over and over again.

But she was not an ordinary person after all, and she quickly returned to normal, saying: "Sun Fucai, send this clock to the saint, and say that Erlang and Jing Ke gave it to him."

"Here." Sun Fucai directed a few people to carefully carry the clock away.

Both Chen Jingke and Li Tai were not surprised by her actions, and it would be strange if she didn't.

When the clock was carried away, Changsun Wugou said again: "Come and sit, let's chat for a while."

The two obediently sat down opposite her, and then handed her the detailed drawings, parameters, and production process of the clock.

Changsun Wugou didn't know much about these things, so he wasn't very interested, he just flipped through them and put them down.

Then he said to the two of them: "I've been following you all along, and you've done a good job this time."

Li Tai smiled and said: "The main reason is that Jing Ke commanded well, and I was the one who contributed."

Chen Jingke said modestly: "Without you leading the team to tackle key problems, I wouldn't be able to build it next year."

The eldest grandson Wugou was very relieved, and said: "Okay, don't be humble, you all have contributed. What I want to talk about is not this matter, but I have other things to discuss with you."

Both of them got serious and said, "Say it."

Changsun Wugou pondered for a while before saying: "Jing Ke gave the profit from the clock and watch to Gewu Ban in order to separate it from Zixiao Temple."

"What I want to ask is, when and how are you going to split up?"
