Thursday is the twenty-fourth day of the Gengshu month of the Renyin year of the lunar calendar.
It is suitable for offering sacrifices, making stoves, getting rid of insects, and coding.
Avoid cutting down trees and getting married.
Follow the normal historical trajectory.
In the far east.
Five days later.
Mr. Lin who wrote "I shall dediate my color to the ihe life ah,irrespetive of peonal will and world" will die of illness, and a certain feudal dynasty will fall again, one of the few that can be called a nation.
Backbone character.
And at the same time.
The British Peninsula tens of thousands of miles away.
Xu Yun was sitting in a lecture theater with hundreds of students, listening to someone's speech on the podium with a drowsy look on his face.
The spokesman was short, somewhat bloated, and had a fleshy face.
He wore a linen shirt with a high stand-up collar on his upper body, and a dark tuxedo and trousers on his lower body.
A standard 19th century British aristocratic dress.
At this moment.
The short, fat man was speaking impassionedly in his speech, and in the first row sat leaders of major universities, including William Whewell and others.
"Dear classmates, I am very happy to see so many young and energetic faces during my visit to my alma mater."
“Thinking back to those days, the professors’ noble ethics of being role models and upright examples inspired and educated me. They set an ordinary but great example for me, which enabled me to cultivate my moral cultivation and hone my will and character.
"
"I still remember the dawn of dawn, the professors came to school on the morning dew and accompanied me in my studies."
"It's a quiet night, and the professors go home in the moonlight. They often worry about the growth and progress of me and my classmates."
Under the ceremonial stage.
Looking at the pudgy man who kept talking, Hubert Ally curled his lips in disdain and complained to Xu Yun:
"What he said was better than what he sang. He also studied on the morning dew. When my father and I were in the same class, we didn't see him five times in one semester!"
"If it weren't for his status as earl heir and his donation of a large sum of money, he would have been kicked out of Cambridge long ago."
Xu Yun smiled and said nothing.
The short, fat man on the stage was none other than the father of Frederick Agar Ellis.
That is the current Earl of Ellis, Vittorino Ellis.
Vittorino Ellis arrived at the University of Cambridge this morning. As soon as he arrived at the school, he was warmly received by the school leaders.
After a half-day tour of the campus, Cambridge University organized such an exchange meeting in the afternoon.
Of course.
The meeting was said to be an 'exchange', but it was actually a personal speech by Vittorino Ellis.
As for the purpose of Vittorino Ellis entrusting the school to organize such a meeting?
Just look at the attendees:
In addition to all members of the Department of Mathematics at Trinity College.
Also present were the heads of various departments of the Student Union, as well as Rossetti and a few other members of the Apostolic Society who had made their identities public.
major in study,
employer,
Head community.
The above three cover almost all of Lao Tang’s social circles.
Think of this.
Xu Yun sighed softly and couldn't help but break into a cold sweat for Lao Tang.
be honest.
If you put aside the variable of yourself, Vittorino Ellis's move will be a decisive blow that overturns Laotang's foundation.
As a question writer in an ordinary town like Laotang, there is no resistance to this kind of crushing situation.
After the meeting.
The position of president of the Federation of Students will inevitably be obtained by Frederick Agar Ellis.
Fortunately, I was there
While Xu Yun was thinking, Vittorino Ellis on the podium continued his speech:
"In the morning, I heard from Dean Whewell that the number of student clubs established at Cambridge University this year has increased by nearly 70% compared to previous years."
"This is undoubtedly a good thing. University should be more lively."
As a result, as he was talking, Vittorino Ellis suddenly turned pale.
His tone suddenly became serious:
"But as the saying goes, drama is not nonsense, adaptation is not random fabrication, and excitement is not nonsense."
"So there are some things I want to say a few more words here."
Hear this.
The atmosphere at the scene suddenly became solemn, and you could hear a needle drop.
Vittorino Ellis seemed not to notice the change in the atmosphere and continued:
"For example, when I was chatting with Professor Prime, I heard that some students had established a club called Gewu Society. The meaning seems to be good."
"But when I saw their activity application, they actually wanted to find the ninth planet in the solar system?"
"The Greenwich Observatory in the UK, the Berlin Observatory in Germany, the Rome Observatory in Italy, there are so many celestial objects that have not been observed by Europe's top observatories. Some people are so naive as to want to calculate it through mathematics?"
After speaking, Vittorino Ellis shook his head and sighed with regret:
"I personally respect the course of natural science, but I think the development direction of certain mathematics is questionable."
"Mathematics has been the core of the classical cultural system for hundreds of years, and there is no need to change its nature now."
After speaking, Vittorino Ellis paused, as if he wanted to increase the intensity of his speech, and then said:
"I even think it can be said that thanks to the efforts of countless forefathers, the edifice of mathematics has been completely completed. At most, there are only two dark clouds floating above it."
"We should focus more on realistic goals, such as developing industry, growing corn, and preparing for the rise of Gaul and Italy."
"Of course, I am not talking about now, but a hundred years from now, these two countries will inevitably become powerful opponents of the British Empire."
"I think the blood they inherited will be stimulated by then, and they will fight to the end no matter how powerful the enemy is. They have to be on guard."
""
Under the ceremonial stage.
Looking at Vittorino Ellis, whose face turned red because he spoke too fast, Xu Yun's expression couldn't help but be a little subtle.
When he heard the first half of Vittorino Ellis's words, he was still a little angry and directly named the Gewu Society. This was basically preparing to kill them all.
Unexpectedly, Earl Ellis changed the topic and almost made him spit out a mouthful of blood.
Anyone who knows the subsequent historical development will know how outrageous what Vittorino Ellis said is.
More importantly.
The old soup that Vittorino Ellis dissed, tmd is Lord Kelvin.
What a wonderful destiny.JPG.
But then again.
If you think about it carefully, it is normal for Vittorino Ellis to say this.
After all, European classic literature not only supports the history of European literature and art, but is also the core system of many wealthy families.
The most representative one is Cavendish introduced in the Northern Song Dynasty copy.
The development of those wealthy aristocrats is inseparable from classical mathematics. Therefore, the development trend of natural science and modern mathematics is actually contrary to the interests of the upper class.
In addition, Vittorino Ellis's family is mainly business-oriented and cares about the trade of workers and even slaves. Naturally, you will feel that the practices of Gokusha are quite outrageous.
As for the subsequent prophecies about Gaul and Italy, it is difficult to evaluate them.
all in all.
Listen to the second half of Vittorino Ellis's sentence.
Xu Yun suddenly found that he was stunned and didn't show any anger at all. He even wanted to shake hands with the other party and sang "I heard that I thank you"
Of course.
Xu Yun's mentality can only represent him personally. Not everyone is like him and can understand the direction of history.
After Vittorino Ellis expressed his attitude, eyes from around him kept scanning towards him and Lao Tang.
Another hour passed.
The ‘exchange meeting’ ended in a delicate atmosphere.
When leaving the classroom, it was obvious that almost all of the students who had a relatively good relationship with Lao Tang kept a certain distance from him.
no way.
After all, for students of this era, the pressure of being an earl is still too much.
After leaving the classroom, Xu Yun and others met outside the corridor.
Xiaomai kicked away a stone, the expression on his face was filled with anger and weakness:
"How can there be such a thing? He is still a dignified earl. How shameless!"
Xu Yun took the initiative to step forward, patted his shoulder with a smile, and comforted:
"Allah, don't take this kind of people to heart. Those who deny wantonly and trample on other people's efforts will generally end up miserable."
"For example, there is a person I know who always maliciously distorts and denies history. He will bark a few words when there is nothing wrong. He just went too far today."
After speaking, Xu Yun looked at the sky and said meaningfully:
"There is a saying that goes well. The vibrating egg of history is buzzing. No matter how hard the old era endures, it will eventually turn into a puddle of running water and wet the sheets."
wheat:"?"
Then Xu Yun looked at Lao Tang beside him and asked:
"Senior Thomson, are you ready for all the preparations?"
Lao Tang's expression was still a little heavy at this time. He took a deep breath to adjust his mood and then said:
"It's ready. The area where the 'Tatara' telescope is located is temporarily under martial law, and the people responsible for guarding it are all my people."
"Besides, Daniel and Stanley are also there, so you don't have to worry about anyone tampering with the telescope."
Xu Yun hesitated for a moment, then nodded slightly.
Needless to say, Daniel.
Daniel Bradley, the second person in the Apostolic Society who recommended Xu Yun, provided a large number of observation records of the Bradley family this time.
Stanley is Edward Bull Stanley.
He was also the first member that Xu Yun and Lao Tang met during the interview at the Apostolic Society, and they had a good relationship with Lao Tang.
However, Xu Yun always thought of him as Edward Smith Stanley, so the impression was never very good.
all in all.
At this stage, Xu Yun and the others have almost prepared everything they can.
Now there's only one thing they can do
Wait until dark
It gets dark very quickly in winter, and less than an hour after the exchange meeting ended, the sky gradually started to get dark.
Another half hour passed.
The visibility of the sky dropped again by a notch.
Xu Yun, Lao Tang and others took the time to have a meal. After all, tonight's events would still consume some energy.
Half past six in the evening.
The sky became pitch black, and stars appeared one after another in the sky.
at the same time.
Relying on the warm-up effect a week ago, a large number of students began to gather around the telescope.
Lao Tang personally sat near the telescope, while Xu Yun stayed in a temporary shed. The shed was filled with tables, chairs, pens and papers, Gauss, the German expeditionary force, and a mathematical team composed of more than ten students from the mathematics department who supported Lao Tang.
The computing team is located here.
Also, consider the fact that it’s dark.
Xu Yun also asked William Whewell to pull some wires to provide sufficient light source.
"Bovart Star Map"
"Hevelius' Star Map"
Xu Yun stood in the small shed and continued to distribute the prepared observation records to the calculation team.
There were a total of 27 German mathematicians who came to Cambridge this time. Some of them passed through Manchester and other places on their way to Cambridge, and they called several British mathematicians to give Faraday a "final farewell", such as
Sylvester and more.
Therefore, there are 32 foreign aids in this group. Counting 11 students from the mathematics department, the total number is exactly 43.
Based on this number of people.
Xu Yun divided them into seven groups and completed calculations based on existing information.
Students who have calculated the orbits of planets should all know this.
In the starry sky, each planet can be planned into a certain coordinate system.
For example, galactic coordinates, equatorial coordinates, ecliptic coordinates, etc.
The so-called galactic coordinate system is actually a polar coordinate system.
It takes the sun as its origin, and the sun on the galactic disk points to the center of the galaxy at 0°.
To the east is the positive direction of longitude, and to the north is the positive direction of latitude.
Equatorial coordinates take the center of the earth as the origin of the coordinate system, and the direction from the center of the earth to the vernal equinox is 0°.
The so-called vernal equinox is the intersection of the equator and the ecliptic, declination is the angle to the south (negative) or north (positive) from the celestial equator (the outward projection of the earth's equator), and right ascension is the angle to the east from the vernal equinox.
Ecliptic coordinates are even simpler.
It is a celestial coordinate system with the ecliptic as the datum plane, and is mostly used to study the motion of celestial bodies in the solar system.
The ecliptic system describes the orbit of the planets around the sun, with its center at the center of gravity of the solar system, which is the position of the sun.
Its basic plane is the Earth's orbital plane, called the ecliptic plane.
Very simple and easy to understand.
Xu Yun publicly used the ecliptic system this time, but used the galactic coordinate system in the calculation stage.
As long as the historical observation records are used in certain calculations through the coordinate system, we can try to decipher the mysteries of the stars.
After everything is ready.
Xu Yun looked around, and Lao Tang, Gauss and others nodded at him at the same time.
See this situation.
Xu Yun took a deep breath, picked up the pen, and wrote one word on the paper:
untie
Note:
I tried voice coding part of this chapter for the first time. Can anyone tell which part it is?
From the beginning to the end of Eisley's words, the chat between Xu Yun and Xiaomai, and the end of the chat to the last part, you can take a guess and use 123 to represent it.
If it's not obvious, I will try some of the pronunciation in the future. If it is obviously inconsistent and everyone can tell which part it is, then forget it. The reading experience is the most important.
