Ming Zuo

Chapter 235
In Deng Yuhan's small laboratory, Luo Yagu, Xue Fengzuo and others saw the astronomical telescope made by Zuozhuang.

"My God, this is definitely the most accurate telescope I've ever seen."

After the field operation, Luo Yagu was full of praise for this astronomical telescope.

Xue Fengzuo looked terrified.

He has just started to learn from Luo Yagu, and he hasn't mastered much knowledge yet.I just heard from Luo Yagu that you can use tools to observe the starry sky in Europa, but I have never seen it in person.

Today, Xue Fengzuo is in the process of changing his thoughts and knowledge, and his understanding of astronomy still retains the traditional Chinese imagination.

For example, the stars are the places where the gods live, far away and not to be profaned.

Now, he has seen the appearance of the moon through the astronomical telescope, and also saw many planets.

There is no Chang'e on the moon, no moon palace, and there is no Wu Gang who exposes his tendons all day long and cuts down trees to seduce Chang'e.

This fact made Xue Fengzuo quite distraught.But at the same time, it further aroused his interest in Western learning.

Over there, Luo Yagu, Deng Yuhan and Zuo Menggeng have already discussed the problem of this astronomical telescope.

Speaking of this, Deng Yuhan was full of praise for Xu Ruolin.

"Zuo's fiancée is the best female mathematician I have ever seen in the world. Without her precise calculations, such an excellent telescope would not have been born."

It wasn't until Xu Ruolin came to Linqing that Zuo Menggeng knew that the inherent mathematical knowledge here was not enough to support the manufacture of larger astronomical telescopes.

It's not that the technology is not good, but the calculation is not good.

For example, the value of the concave-convex ratio of the lens cannot be obtained using traditional algorithms.

The measuring tools used by craftsmen are also unable to perform calculations.

With the help of Xu Ruolin, the standard ratio of the astronomical telescope was obtained by using the logarithmic algorithm.

According to Xu Ruolin's instructions, a logarithmic ruler was created.

The appearance of the logarithmic ruler, in turn, helped the manufacture of heavy artillery.

For these things, Zuo Menggeng can only feel that industry and science are indeed an extremely complex and closely related system.Any little bit of progress can have a huge impact.

What Xu Ruolin is currently researching is to make a complex logarithmic ruler.

The complex logarithmic ruler is of great help to the calculation of square roots and powers. Once successful, Zuo Zhuang will have a huge improvement in the manufacture of machine tools.

Before the invention of the computer, the influence of the ruler on human society lasted for more than three hundred years.

Although Zuo Menggeng is not very proficient in mathematics, he also knows that this matter is great, so he fully supports Xu Ruolin's research.

He also said a word to Xu Ruolin with his limited knowledge of mathematics.

"The logarithm is the inverse operation of the exponent."

This is a principle known to junior high school students in later generations, but in this era, the significance is undoubtedly huge.

Xu Ruolin didn't believe it at first, but after doing the calculations herself, she almost broke Zuo Menggeng's head.

I just want to see how a person with such scum in mathematics can discover this mystery.

Just because of Zuo Menggeng's words, Zuo Zhuang's mathematics level has been improved for nearly a hundred years.

The happiest person among them is Xu Ruolin.

What she did was supported by no one in the Xu family except Xu Guangqi.

Everyone thinks that she is a girl, so she should stay out of the house, stay out of the house, and learn how to be a knitter. When she is old enough to marry, she should be a husband and a child.

Yes, although the Xu family is a Christian family, except for Xu Guangqi, the openness of the others is far from enough.

After arriving in Zuozhuang, Xu Ruolin has no restrictions, and she does what she is good at and likes.

The people here are not prejudiced because she is a woman, on the contrary they are very convinced of her ability.

This may be because she is Zuo Menggeng's fiancée, and people regard her as the future mistress, but the feeling that she is useful makes Xu Ruolin reluctant to think about leaving.

In the next few days, Xue Fengzuo participated in the academic discussions of Xu Ruolin, Deng Yuhan, Luo Yagu, Bi Maokang and others, and even met famous people such as Hou Xun, Li Banghua, Geng Ruqi here.

With the baptism of academics and the influence of famous officials and scholars, Xue Fengzuo decided to stay in Zuozhuang and join Xu Ruolin's mathematics research.

Although Zuo Menggeng didn't know how good he was, he also felt that he was a talent.Since he is willing to stay, it must be a wish.

Not only did Xue Fengzuo stay, he also wrote two letters and asked someone to send them to Zhili.

He knew that there were still two teachers who were struggling.

They should take a look at Laiqing and see this different place.

With the arrival of Hou Xun, the imperial court's disposal of Zuo Menggeng also arrived.

For the punishment of being demoted two ranks, although the whole new army was very angry, Zuo Menggeng didn't care.

This punishment is tantamount to no punishment.

Even if Chongzhen deprived him of his status as a general of the Dongchang Association, wouldn't the whole new army listen to him?
Zuo Gui brought an old man to visit him.

"Lu Jingyuan from the Changfeng Escort has met General Zuo."

Zuo Menggeng heard about Lu Jingyuan from Zuo Fu and Zuo Gui.During the trip to Dongping, Lu Jingyuan was of great help.

"Why does Boss Lu have the time to come to my fluffy piss?"

His kindness reassured Lu Jingyuan a lot, and he hesitated to tell the matter.

"The villain is reckless in the world, with a humble body, I didn't dare to insult General Zuo. But morally, the villain is helpless and abrupt. General Zuo, please save Li Tianwang."

After hearing what Lu Jingyuan said, Zuo Menggeng knew that the battle between Li Qingshan and Guo Yunbiao in Yanzhou Mansion had changed.

Although Li Qingshan has a high reputation, he is quite popular.However, most of the people he can gather are idle people.Even if there are people with outstanding military strength among them, if they are scattered, they will not be able to exert much power.

On the contrary, what Guo Yunbiao is running is the home of the White Lotus Sect.Not only are the soldiers strong and horses strong, but they are also well-organized. Even against the official army, they are capable of fighting.

The two sides have been fighting since the beginning of the year, and Li Qingshan's defeat has been evident since the fight.

According to Lu Jingyuan, Li Qingshan still has more than [-] brothers around him, and they are besieged by Guo Yunbiao in the village of Liangshan.

Guo Yunbiao hated Li Qingshan to the core, leaving other good places alone, he must destroy Li Qingshan first.Therefore, the siege of Li Qingshan has been going on for more than a month.

If it weren't for the fact that the White Lotus Sect's military quality is also sloppy, Li Qingshan would have died long ago.

After the incidents of the White Lotus Sect in various places, Lu Jingyuan knew that Li Qingshan would be retaliated by Guo Yunbiao, so he sent his subordinates to Yanzhou Mansion many times to inquire.

Knowing that Li Qingshan was in danger, Lu Jingyuan became anxious, but there was nothing he could do.

He is just a dart runner. Although he has a reputation in the Jianghu, people in the Jianghu are useless when it comes to fighting.

After thinking about it, he thought of Zuo Fu and Zuo Gui.

Now Zuo Menggeng is doing such a big thing that no one in Linqing knows or knows.The new army brigade also trains outside the city every day, with extraordinary power.

To save Li Qingshan, we can only rely on Zuo Menggeng's soldiers.

Zuo Fu disappeared like a ghost, but Lu Jingyuan couldn't find him.But Zuo Gui has always been in charge of the activities of the three religions and nine streams in the world, and he happened to be in a confrontation with Lu Jingyuan.

Zuo Gui had a good impression of this chief escort, and he also accepted his original feelings.

It happened that Zuo Menggeng had just been reprimanded by the emperor, and was about to send troops again, so he brought Lu Jingyuan in front of Zuo Menggeng.

The new army has actually been discussing the issue of sending troops these days.

There are nothing more than two directions, one is Yanzhou Prefecture and the other is Jinan Prefecture.

As for Qingzhou Mansion...

Zuo Menggeng decided to ignore it, let King Heng suffer more.

But no matter what, the ultimate goal is to force the White Lotus Sect thieves into the Yimeng mountain area.

Since Lu Jingyuan came to ask for help, Zuo Menggeng directly decided to fight Yanzhou Mansion first to save Li Qingshan.

Li Qingshan has great prestige in Dongping Lake area, with his support, the new army will gain a piece of land for nothing.

Such a cost-effective deal, when Zuo Menggeng said it, everyone agreed.

But to beat Guo Yunbiao, there is still a problem that cannot be ignored.

"The water network in Dongping is dense, and the White Lotus Sect's lair is even in the water. But our army doesn't have much experience in water warfare, so we need to pay attention."

Liu Yiyuan gave full play to the duties of chief of staff.

Deputy Chief of Staff Zuo Yong also mentioned a problem.

"For water warfare, heavy artillery cannot be used. Zuoying artillery also needs a strong enough ship."

Both the canal and the Dongping Lake belong to the inland water system.

The size of the ships that can sail here can be imagined.Not to mention the heavy artillery, even the Zuoying artillery might not be able to withstand it.

Zuo Menggeng was not intimidated by the difficulties, but said: "In any case, water warfare is one of the issues we have to face. Even if it is not important now, we will have to experience going to Jiangnan and going to sea in the future. I think it is not as good as Taking advantage of the fact that the White Lotus Sect is not strong enough, it would be better to train our army's water combat capabilities first."

When everyone thinks about it, it is indeed the case, and the hesitation in the face of difficulties is eliminated.

The next step is for the major families to collect ships, and then select the appropriate ones to practice first.In particular, it is necessary to adapt to the artillery so as to master the skills of firing artillery in water warfare.

At the same time, the intelligence department and scouts were also sent out, and began to collect information in the Dongping area as a reference for the upcoming expedition.

After resting for nearly two months, the new army will be dispatched again.
