Chapter 484 Calculus

The emergence of propeller blades can be said to be an accident, or it can be said to be inevitable.

The process of industrial construction is very fast.

Although the industrial production of the whole world now relies on water power, the utilization of water power in Dongping Industrial Zone can be said to be the pinnacle.

The workers here have discovered that it is very inefficient to rely on the natural flow of water to drive the machinery.Therefore, countless large and small water tanks have been built along the entire Dawen River.

It is a common practice here to use the water tank to store water to a certain amount, and then increase the impact of the water flow by pressurizing to provide greater kinetic energy to the machine.

Xiong Wanshui made the inclined waterwheel blades, which is actually the same reason.

But Zuo Menggeng knew that the one he made was very crude, and it wasn't the most scientific and powerful blade at all.

But Zuo Menggeng is also a layman on how to manufacture qualified spiral blades.

Zuo Menggeng didn't even understand the calculation of blade curvature alone.

But he knows the principle.

Zuo Menggeng called the research team of the School of Mathematics who is resident in the industrial zone, and Zuo Menggeng made a request, hoping that they could find a way to calculate better blade curvature data.

With this data, the casting of the blade can be carried out.

Of course, the follow-up will have to solve the material problem of the blade.Otherwise, cast blades are probably useless.

But the problems need to be solved one by one.

Zuo Menggeng didn't expect to be able to apply this kind of propeller blade directly to the ship at once.

If it is only used on industrial machinery, the strength should not be so high.

He is the leader and only asks questions.

But the research team was very worried about this.

This project team was sent here by the School of Mathematics to practice. In addition to helping industrial production solve some calculation problems, it also came to increase practical experience.

As a result, Zuo Menggeng's request exceeded their capabilities.

Seeing no progress, the team leader gritted his teeth and wrote a letter to the School of Mathematics in Linqing.

Only five days later, Zuo Xianmei came with Zhang Lingxi.

"Brother, you are too. How can they solve such a difficult problem? You almost drove them to death."

Looking at the angry Zuo Xianmei, Zuo Menggeng couldn't help being happy.

"Can you solve it?"

Zuo Xianmei proudly raised her beautiful neck like a white swan. "Hmph, if I can't solve it, then no one in this world can solve it."

As she spoke, she took the materials, spread out various tools, and wrote one symbol after another on the paper that made Zuo Menggeng dizzy.

"If you want to calculate a reasonable arc, you can only rely on calculus..."

Zuo Menggeng was taken aback, and quickly asked, "Calculus? How do you know calculus?"

It's not that he lost his composure, it's just that this incident is too surprising.

Zuo Menggeng clearly remembered that when he first taught mathematics knowledge, he never involved calculus.

Because of his mathematics level, he couldn't reach that level.

Moreover, calculus in today's world is still in its infancy and is not systematic, let alone the concept of calculus.

Why did Zuo Xianmei come here as soon as she opened her mouth?
Could it be that this sister also has a soul in her head?
Zuo Xianmei didn't understand why he was so surprised.

"Xunzi has a saying: the one who makes the smallest is bigger, and the one who knows the smallest is the work. I call it calculus, why not?"

Zuo Menggeng was dumbfounded, besides giving a thumbs up, he was also full of curiosity.

"How did you discover calculus?"

Zuo Xianmei blinked and found his head.

"It's not the piano you made, brother. Dean Deng Yuhan said that the piano seems to be able to solve the proportional relationship between the wavelength and the string length. I was curious, and after asking more, I found that rhythm seems to be quite similar to mathematics and physics. Later, I asked Nian Taigong for advice, and he told me that my discovery seems to be able to solve the problem of Lulu records in "Historical Records."

Zuo Menggeng was in a daze, he never imagined that the piano he made, originally only wanted to be the king of musical instruments to sell for money, but in the end it solved the problems of mathematics and physics.

Does this count as unintentional insertion?

He didn't know that the twelve equal temperament is the source of the birth of the piano.

And the person who discovered this rule was a prince of Ming Dynasty.

That is Xiaozheng Wang Zhu Zaiyu.

Zuo Menggeng didn't know this person, neither did Zuo Xianmei.

But the piano obtained by Zuo Menggeng reversely deduced the twelve equal temperament.

According to this law, Zuo Xianmei reversely deduced calculus.

Not only that, Zuo Xianmei said happily: "Brother, I found that the calculation of calculus can be expressed by geometric coordinates, and it is currently being perfected. If it is successful, it should be able to help you calculate the curvature of the blade."

Zuo Menggeng looked at the horizontal axis and vertical axis drawn by Zuo Xianmei casually, as well as the coordinates of the lines above, he was already numb.

Well, the analytic geometry is out.

This younger sister who was originally very traditional and elegant gave him too much surprise.

I really don't know where her limit is?
Maybe in the future history of the world, she might become even more shining than herself.

Watching Zuo Xianmei lead a project team of more than a dozen people to do the calculations, Zuo Menggeng wisely did not interfere and left space for them.

He just ordered Zuo Dai to do his best to meet the needs of these people in terms of logistical support.

On the fifteenth day of the first lunar month, Zuo Menggeng, who continued to travel south, came to Mengyin.

At this time, the weather has begun to warm up, the earth is civilized, and the construction of the Mengyin Reservoir, which was originally suspended, has started again.

"Hey, in order to rob someone, I actually got into a fight with Fu Yusun."

Dang Huanchun had a red mark on the left side of his face, which has not subsided so far. It seems that there was a real fight.

Zuo Menggeng couldn't say anything about this, except to hold back his laughter.

The source of this batch of manpower obtained by Mengyin County is worth pondering.

It is no longer just people from neighboring Shandong such as Gyeonggi and Henan who come to seek survival, but even people from Shanxi and Huaiyang come here.

Because in October last year, Shanxi was hit by an earthquake, which caused a large number of people to be displaced.

Except for some who went to join the Northwest Rebel Army, some who starved to death, and some who were stubborn, they heard that Shandong was rich, so they ran all the way here.

The same is true for the people of Huaiyang.

The famine in Huaiyang last year was very serious, and countless people died on the side of the road.

In order to survive, he must either fall into the grass and become a bandit, or he must leave his hometown.

Before I knew it, the news of Shandong's prosperity had spread far and wide.Therefore, the people of Huaiyang and Shanxi also rushed here.

Today's manpower gap is so big, this side naturally welcomes all comers, and the manpower has been digested in a short period of time.

Even in order to grab more labor, chief officials from all over the country did not hesitate to stage full martial arts.

Dang Huanchun is a pure literati who has read poetry and books, so of course he is powerless.Facing Fu Yusun, who used to be Zuo Menggeng's secretary, he didn't need to think about it, and he definitely couldn't get any good.

But Dang still didn't care, and he was satisfied with the more than [-] labors he had snatched to start the reservoir.

Zuo Menggeng was also quite satisfied, and put forward new requirements for Dang Huanchun.

"Leave the matter here to Qi Biaojia. You go and manage Yizhou."

Want to change places?
Dang Huanchun was only stunned for a second, then readily agreed.

Mengyin is just a county, and it is still a poor county in the mountains.

Yizhou is different, it is an important town in southern Shandong, with a wide range of radiation.And because it is next to Nanzhili, it will be very important in the future.

When he was in Daming, he was the county magistrate.Here, he is still the county magistrate.

Now, it's finally time to get promoted.

Fu Yijian ran from a distance, panting, but the information he handed over was very important.

"Commander, the Dongjiang rebels have moved and headed straight to Yidu."

Zuo Menggeng didn't even read the information, and laughed on the spot.

"Hahahaha, it's finally moving, I'm so sorry for waiting."

He didn't care about anything else, and immediately left Mengyin and rushed all the way to Yishui.

This is the headquarters of the third division.

Next, the third division will play the leading role.
