Xinshun 1730

Chapter 115 Squeezing the Last Drop of Juice
Not all emperors like to pretend to be beeping, but Li Gan undoubtedly belongs to this kind, at least Liu Yu thinks so.

He is a foreign academician who has long been eyeing the Russian Academy of Sciences.

In the next 20 years, the West French Party, the Conservative Party, the German Party, the Russian Party, foreign women, foreign women's lovers, local nobles... will mess up the Russian political situation, especially when the little tsar dies, and the Privy Council puts the German widow Please come back as Tsarina even more so.

Scientists also need to eat and want to live a good life, and research also needs a stable environment.

Since this group of people can go to the wild Russia, if Dashun offers better conditions, they will definitely be willing to come.

It's not that Liu Yu is not confident, but that his strength does not allow him to be confident in front of a real master.

A person like Euler... the light blinds his eyes.

A strongman who has instilled mathematical traditions in the Russian Academy of Sciences by himself and made Russian mathematics strong for hundreds of years, if he can deceive or hire the capital, and realize Leibniz's idea of ​​the Beijing Academy of Sciences, it is undoubtedly very promising good.

To be more realistic, if Dashun wants to develop the South Seas, prosper the navy, and get Australia as the last dish in the last corner of the era of great voyages, Euler is even more needed.

Because of... navigating.

The "older generation" such as Newton came up with a sextant, and latitude navigation is no longer a problem.

There is the Southern Cross in the south, and the Polaris in the north. You can know where the north and south are by looking at the stars.

Knowing north and south, and then knowing things, you can know your specific position on the earth.

This is indispensable for navigation without a reference object, and it is also the only way for Dashun's navigation to break away from the needle road song island jumping method.

Euler is the key figure in solving this problem.

There are generally three schools of thought when it comes to solving the longitude problem.

Witchcraft.

Technical school.

math school.

Britain is now offering a reward of £2 to anyone who can solve the longitude calculation.Approximately equivalent to 8000 taels of gold.

The method given by the witchcraft school is as follows:

Witchcraft believe in telepathy between twin brothers, whether human or dog.So, get a litter of dogs and let the puppies grow up together.Then when going to sea, let the crew bring a dog.Every day at zero o'clock in London, the dog brothers who were left on the land with needles.

They believe that the dog brothers on board have telepathy and then scream.

The crew heard the dog barking, judged the local time by observing the sun, and judged their own longitude through the time difference.

Apparently the Witches couldn't get the £[-].Because it's pure fucking bullshit.

The technical school believes that this is simple, as long as I create a clock that keeps accurate time regardless of turbulence, cold and heat, seawater erosion, salinity, ship steering, etc., according to the time difference between the local time and London time, no matter what Solve the longitude measurement problem?
However...it's not easy.At least at this time, no one has done it yet.

Dashun's mechanical manufacturing technology is already backward, and this thing is also within the scope of "extraordinary skill and obscenity".

Besides, Liu Yu didn't think he could persuade the emperor to take out 8000 taels of gold from the treasury, a reward of [-] pounds, and the honor of the royal family to recruit such a lowly craftsman.

If this is the case, there will undoubtedly be an uproar, and it will be seen that Dashun is learning from Meng Yuan, and let the craftsman climb to such a high height.

Liu Yu didn't dare to set this fire at this time, it would easily burn himself to death.

Moreover, it is useless to estimate it, Dashun's watch manufacturing level is too far behind.

The witchcraft school is no good, and the technology school is useless, so only the mathematics school is left.

There is always a "number" in the six arts of Confucianism, and the voice of opposition can be much smaller.

It is said that Lord Niu first came into contact with this problem and thought it was very simple. As long as he drew an accurate star map and the orbit of the moon, wouldn't it be solved?Then...he went to work on theology and stock trading.

Mathematicians now have solutions.

And this solution requires three things.

Accurate star map of the Northern Hemisphere.

Accurate star map of the Southern Hemisphere.

Moon orbit calculation, calculus.

There is a saying that if you are not crazy, you will not be holy.

The pursuit of science makes many scientists act a little crazy.

Flamsteed, who founded the Greenwich Observatory, looked up at the starry sky for 20 years, stood on the shoulders of giants, and drew a highly accurate star map of the northern hemisphere.

But he is a "true Virgo perfectionist obsessive-compulsive disorder", thinking that the star map he drew is not extreme enough, so he has been refusing to publish it, and it must be perfect.

It is said that in mechanics and mathematics, Newton was not born in the sky, and eternity is like a long night.But Mr. Niu's character is really a bit...

In order to obtain this star map, Newton asked Halley of Halley's Comet to steal Flamsteed's northern hemisphere star map.

As a result, Flamsteed burned a lot of the northern star map out of perfectionism and obsessive-compulsive disorder.

It was not until his death a few years ago that his descendants and disciples published this star map.Lord Niu plagiarized some results, and decisively deleted Flamsteed from the reference list when the second edition of "Principles of Natural Philosophy and Mathematics" was published.

Now, the "scholar" Newton is dead, and the "British Tables" for the Northern Hemisphere compiled by the younger generation has just come out.

Three problems of the mathematical school solve one.

The star map of the southern hemisphere, as the second problem of the school of mathematics, a French "madman" La Carré, in order to draw an accurate star map of the southern hemisphere, went to the then desolate Cape of Good Hope alone.

This person lived alone there for more than ten years, and finally completed the southern hemisphere star catalog.

The second problem of the mathematical school is also solved.

All that remains is the third problem: the precise orbit of the moon.

If these two star maps had been published 30 years earlier, perhaps Newton would have been able to settle down to calculate the lunar problem.

But these two pictures only came out. Newton just died last spring, and they all said that he could eat hairless meat without a butcher, but scientifically, sometimes it is really difficult to eat hairless meat without a butcher.

When calculating the orbit of the moon, it is inevitable to consider the "three-body problem", because in addition to the moon and the earth, a sun is also involved.

The three-body problem is hard.

Euler was the first person to try to solve the three-body problem. He was troubled by the three-body problem for 40 years, and finally felt frustrated that there was no general solution to the three-body problem.

But he found several special points in the paper, which were carried forward by the next generation of Lagrange, and also provided the basis for the calculation of the lunar orbit.

It can be said that without Euler's research on the three-body problem, there is no way to accurately calculate the orbit of the moon.

There is no way to accurately calculate the orbit of the moon, and there is no way to make an astronomical almanac and moon phase map.

It is impossible to make an astronomical almanac and moon phase chart, and even if there are star charts in the northern hemisphere and star charts in the southern hemisphere, there is no way to obtain the longitude of this place through calculation.

If you can't calculate the exact longitude, dominating the Seven Seas is a daydream, and dominating Nanyang and Australia is a daydream. They are all dreams.

Liu Yu knew his two brushes well, and he was very worried, and he was not qualified to study the three-body problem at all.

Only rely on Euler, the big cow who makes the teeth of future college students hate before the exam and has nightmares again and again.

Once the accurate moon orbit is obtained, all that remains is to hire a group of "mental workers" to calculate the moon phase map and orbit, and write them into tables similar to "trigonometric function table" and "logarithmic table", so that the sailors can And Voyager doesn't need a level of calculus, rote memorization.

Look at the table, look at the moon and stars, and look up the table to determine the longitude at this time.

Once Dashun is the first to produce the moon phase map and astronomical almanac, it will not only be a benefit of navigation, but more importantly, it will have the right to speak in the future world: Why is Greenwich Observatory zero degrees of longitude?Because Britain developed the nautical clock, it was the first to produce the moon phase map in the astronomical yearbook.

If it is done in Dashun, it is natural that Quanzhou or Guangzhou or Ningbo will be the prime meridian.

If you want to sail, you have to have a copy of the astronomical yearbook and moon phase chart of the Beijing Publishing House, which will naturally affect the naming of many rules.For at least 50 years, nautical clocks are still a luxury item that ordinary people cannot afford, nor can ordinary craftsmen make.

If Euler can be lured to the capital, whether it is strength or a long tradition of mathematics, it will be an incalculable wealth.

A problem that can be solved with money is not a problem. It is not a problem to spend 1000 taels of silver and ask someone to bring two star charts from Europe.

It is no problem to spend thousands of taels of silver and hire a group of Western mental workers to calculate the moon phase map and longitude table.

But there are still many things that money cannot solve.

In the war against Russia, Liu Yu wanted to squeeze out all the benefits he could get, not the few pieces of land.

He himself didn't care much about those pieces of land. If he got it now, if the reform was not successful, he would have to lose it in the future; if he lost it now, as long as the reform was successful, he would still have it.The true belonging of the outer northeast and Siberia lies in whether the first railway station built there is written in Chinese or in Russian.

That's why Liu Yu attached great importance to the Rakshasa mission this time, squeezing the last bit of juice out of Russia, hoping that the mission could send some signals.

With the help of the once-in-a-lifetime 20-year political turmoil in Russia, people like Euler have one more choice: maybe they can go to Dashun.

The death rate of sailing is too high, and most scientists would not choose to take a boat, after all, they still have wives and children.

It is much safer to go to Siberia.

Once the envoys can be stationed in Rakshasa, and the Raksha Tsar is enthroned, he will go to celebrate. As long as the opportunity allows, and the political situation in Russia is in chaos, he can try to fool Euler and others.

Of course, there is a premise:

Euler must think that Dashun's side is not a desert of mathematics, but that there are people who can discuss mathematics problems with him.

It just so happened that the emperor, in Liu Yu's eyes, was another character who liked to put on a beep, so this was a perfect opportunity.

He said he was [-]% sure, so he was [-]% sure.

It is not a problem to ask a few questions to embarrass the group of students from the Academy of Sciences who came with the envoy.

If you can come up with a few questions and send them back to Petersburg to arouse Euler's interest, it will lay the foundation for fooling Euler in the future.

Thinking that since the emperor blurted out how sure Liu Yu was, Liu Yu knew that the emperor was moved.

"Your Majesty, I heard that the Raksha Mission intends to perform martial arts, so you don't need to look at it. I have already won in the north, and I already have martial arts. Even if they intend to show their martial power, I will wait and see, so what can I do? Anyway, the Tuotu is I am facing, and they are the ones who retreat."

"Wenzhiwugong, Wenzhiwugong. With martial arts, there should be Wenzhi. Your Majesty can use the name of 'examination, teaching and learning' to frighten the 'erudites' in the Raksha Mission, so that the name of Wenzhi in my court can be waved. Far away. It also makes them dare not think again."

"If it's martial arts, Luo Sha will know that we are still behind in terms of military equipment when he sees that we are still using matchlock guns, thick formations, and cold weapons for protection. On the contrary, he may feel contemptuous, and may dare to ask for a price in subsequent negotiations. "

"And if we treat the text as a deterrent, people with insight in the country will know the depth of our dynasty."

"Why? If mathematics is strong, artillery will be strong; if science is strong, armaments will be strong; if geometry is strong, building and attacking fortresses will be easy."

"Compared to Rakshasa, I am ten times richer and have five times higher taxes. Even though the Beijing camp is still using matchlock guns, Raksha sees that I am strong in science and mathematics, so I will definitely understand that as long as you have money and a heart, you will be able to do it in a few years. It is beyond the reach of Rakshasa. In future negotiations, we will definitely make a lot of concessions."

"As for the scriptures, Rakshasa doesn't understand, and they don't know the prosperity of my dynasty. So I can only make a fuss about this matter."

Ever since Jinshuiqiao asked the right question that day, Liu Yu has been saying that Dashun's military system is backward.

Originally, Li Gan didn't know where he was falling behind, and he hadn't seen Luocha's regular army's tactics in the First Battle of Northern Xinjiang, but the incident of attacking the fortress proved that Liu Yu's words were true.

After that, Liu Yu also made pictures to explain the significance of the bayonet, the benefits of fast maneuvering without armor, and... saving money.

At this time Liu Yu mentioned this matter again, and Li Gan felt that this was the case.

When it comes to performing martial arts, those who don't know how to do it can watch the excitement, and those who know how to do it can see that there is something wrong with Dashun's military system.

The previous battles in the northwest were all due to problems with the coordination of the huge thick phalanx and the cover of hot and cold weapons, which led the Junggars to seize the opportunity.

At that time, the "Grand Parade" that was supposed to show the military's prestige was seen by the Luocha people knowingly, and then gave an evaluation of "80 years behind". It would be self-defeating.

A few days ago, Yi Guogong also mentioned this issue, and he firmly refused to agree with Luo Sha to demonstrate the skills and artillery skills of the Western Army. The Rakshasa saw clearly the underpants.

Although Li Gan said that he likes to pretend to be a beep, he always pretended to be from the perspective of an emperor: Liu Yu was the one who made the plan for attacking the fort. It is acceptable to ask the emperor to pretend to beep.

The godson of King Luocha was arrested, and he wanted to imitate Li Er and get a foreign big shot to be an actor by his side. This was caught by a courtier, which is equivalent to being caught by himself. This beep can also be pretended a little bit.

But he is not a person who hides his ears and steals the bell. He will not do it where he or his courtiers have no strength to pretend to beep.

At least this time when the Rakshasa Mission came to visit, he strictly ordered all localities: it is not allowed to hang colorful flags on the carts of the Rakshasa Mission, and write the word "tribute".Anyone who does this will be considered guilty of "blinding the hearing".

Because people really did not come to pay tribute, Western missionaries said it was "tribute" for various purposes, and they could still pretend not to know. After all, they didn't take the initiative to make them say that those gifts were "tribute".

Just like the fact that one day in the future, if you really get the tribute from the Rakshasa, it may not be the emperor who did it, but at that time, enjoying the glory of the tribute will be a matter of course and a peace of mind.

Now that Liu Yu proposed to pretend to be beeping on the "Cultural Rule", this flattery is very local, and Li Gan is still quite itchy about it. What belongs to the courtiers is his own, and the imperial power thinking is naturally so.

The emperor wants to be happy, and Liu Yu wants to benefit, so they just use each other to get what they need.

Now Liu Yu talked about the content other than flattery from the perspective of future relationship negotiations, which made it even more difficult for Li Gan to refuse.

He is at ease when Liu Yu handles affairs.

If it is said to be [-]% sure, then it is [-]% sure, and it has been seen a few times before that he doesn't need to ask, Liu Yu will naturally handle things well.

Now Liu Yu was waiting for him to nod his head, Li Gan pondered for a while, and then said: "Your words are very true. The Raksha Mission has now arrived in Zhangjiakou, and will arrive in Beijing soon."

After reminding Liu Yu that the time is coming soon, Liu Yu did not say a word, that is, he told the emperor by default: time is fine, enough is enough.

The two completed the conversation tacitly.
