The sun shines brightly after the rain, a rainbow stretches across the blue sky, and the air is fresh with a hint of sweetness.
Göttingen is the well-deserved academic capital of Germany, a city with the highest average academic level.
In 2022.
In this small city of only 130,000 people, there is one college student for every four people.
46 Nobel Prize winners have either studied here or taught here.
Looking around the world, you would be hard-pressed to find another city like it.
At this moment.
Southeast of the University of Göttingen, in front of a small house near Jaromi Park.
An old man in his sixties was leaning leisurely on a chair, flipping through a book with great interest.
On the cover of the book page is a title:
"Experimental Research in Electricity" (Volume 2), printed and published by Royal Society Press.
In addition, there is a line of small words below the title:
Author: Michael Faraday.
"Substances can be non-magnetic, but the processes of electric induction and electrolysis prove that electricity has a huge advantage in energy, and they can act like magnetism."
"To sum up, diamagnets will repel magnetic lines of force or disperse them, while paramagnets will attract or concentrate magnetic lines of force."
"The above is the entire content of the second volume of "Experimental Research in Electricity". The third volume is expected to be released within three years. Postcards, razors and balls can be sent to the House of Grace at Hampton Court Palace, Surrey."
After reading this paragraph.
Snapped
The old man, who had reprinted this work for the thirty-seventh time, closed the pages of the book and slapped it onto the small round table next to him.
His originally relished expression suddenly changed, and he cursed:
"It was clearly agreed that it would be three years, but three years later, another three years, and three years later, another three years, and the promised update keeps being delayed!"
"The last chapter was so broken, Faraday, Verdammte shoot i?e!"
The assistant on the side looked at the angry little old man with a helpless but funny expression.
As the founder of the Göttingen School of Mathematics, the little old man in front of him single-handedly made Göttingen the birthplace of modern mathematics and is famous in Germany and even Europe.
A look at European academic circles.
Nowadays, there is only one person who can make the little old man crazy and helpless.
That's Michael Faraday.
The first person in contemporary physics wrote the first word of "Experimental Studies in Electricity" in 1839. It has been 11 years since then, but only two volumes have been updated.
But that person was still a jerk and didn’t say anything.
Every time someone sends a reminder letter, the person responds with a perfunctory reply of "I'm fixing it, I'm fixing it", which is really abominable!
I don’t know how long this old man will be angry this time. It will be bad if he gets sick from anger.
Just as the assistant was thinking, a figure suddenly appeared on the path not far away.
The person who came was a young man with gold-rimmed glasses and a beard all over his face, but what was more eye-catching was his hairstyle:
The temples are shaved very thin, and the hair on the top is neatly combed to the left. He looks a bit like a high-quality human male from later generations, as if he would drag his hips to perform a dance for you as he walks.
At this time, the young man was holding a piece of tissue paper tightly in his hand, his steps and breathing were a little messy, and he shouted to the little old man from a distance:
"Teacher, teacher!"
The little old man frowned upon seeing this, obviously not satisfied with the young man's panic.
So he put his hands behind his back and did not take the initiative to greet the other party, with a cold expression.
Just watching the other party running in front of him with solemnity, he just said:
"Bornhard, how many times have I told you that we mathematicians must not be impatient."
"When people are impatient, they may make mistakes in the calculation process. Look at me, I never do."
As a result, before the little old man could finish his words, he was interrupted by the young man opposite:
"Teacher Gauss, something happened, something really big happened!"
The little old man, Friedrich Gauss, couldn't help but frown, and the dissatisfaction on his face became more and more obvious.
Since his most outstanding disciple Ferdinand Eisenstein was imprisoned two years ago, Gauss has regarded the young man in front of him named Bornhard Riemann as his successor.
Riemann's performance is obviously okay on weekdays, but why is he suddenly so flustered today?
Then Gauss sighed and said seriously:
"Bornhard, I have taught you countless times that even if you encounter a big thing, you must stay calm. Do you understand?"
"We are in the heart of Germany, what kind of earth-shattering thing can happen? It can't be that Faraday is about to die, right?"
""
Riemann swallowed and said weakly to Gauss:
"Teacher, you are right. We just received a telegram that Mr. Faraday is critically ill."
"?"
Gauss was startled when he heard this, and his mind was obviously a little out of control.
After regaining consciousness.
His body leaned forward sharply, his voice suddenly rose a few points, and spittle spurted out:
"What did you say?"
Riemann wiped the spittle that Gauss had sprayed on his face and wanted to tell the teacher that foie gras had too high cholesterol and that he was in bad health after eating too much, but in the end he said honestly:
"Teacher, about an hour ago, we received a telegram forwarded from Berlin."
"The sender of the telegram is Cambridge University. The content is that Mr. Faraday is critically ill. We hope we can rush to Cambridge University as soon as possible to see him for the last time."
"Then why didn't you tell me earlier!"
Gauss snatched the telegram from Riemann's hand, glanced at it briefly, and immediately his face turned red.
A few seconds later.
He picked up Riemann's collar with one hand and walked away:
"Let's go to London!"
"Teacher, please calm down. You may not be able to buy a ticket at this late hour."
"Then let's paddle across by ourselves!"
""
Similar scenes happened almost simultaneously in every corner of Germany.
Except for a few individuals who could not be contacted, a total of twenty-seven mathematicians of different ages set out for the UK.
Of course.
Xu Yun, who was on the British Peninsula, knew nothing about this. After leaving Faraday's office, he went to the library to study as usual.
Early next morning.
Xu Yun came to an open space early in the morning, and met a big guy with Lao Tang and others:
The artifact from the Royal Greenwich Observatory is currently the largest bovine retroreflector telescope in the world.
This telescope also has an official name, called 'Tatara', which sounds very much like a TV series from later generations.
The entire body of 'Tatara' is made of steel, with a diameter of 1.6 meters, which is much thicker than the one Xu Yun originally assembled in the Northern Song Dynasty copy.
However, compared to the telescope in the Northern Song Dynasty copy, ‘Todoro’ is slightly shorter in length:
Its length is 26 feet, equivalent to a standard measurement of about 7.92 meters.
Xu Yun chose a high-lying open space, which was about five hundred meters away from the area where he had previously conducted photoelectric effect experiments.
It was mentioned earlier in the Northern Song Dynasty copy.
Observations with astronomical telescopes are greatly affected by terrain, and the higher the terrain, the better.
For example, when Lao Su and others observed the moon, they chose a hillside outside Bianjing City.
But now, in order to stir up as much heat as possible, Xu Yun obviously cannot place the observation location outside the school.
Therefore, he had to relax his requirements on observation conditions and chose such a relatively high point in the town of Cambridge.
This approach will inevitably bring resistance to the observation, but it is already the best method Xu Yun can find at present.
The process of assembling the equipment does not require Xu Yun to do it himself. At this time, he is standing aside, flipping through a stack of documents in his hand.
Besides Lao Tang, there was also a middle-aged man with glasses and extremely obvious nasolabial folds standing next to him.
after awhile.
Xu Yun closed the manuscript in his hand and said to the middle-aged man with gratitude:
"Mr. Airy, I really want to trouble you this time."
That's right.
This middle-aged man was none other than Hubert Airy's father, George Bedell Airy, the current director of the Greenwich Observatory.
Hearing Xu Yun's words, George Beadle Airy glanced at him and shook his head slightly:
"Since we have agreed to cooperate with the Gewu Society, these things are naturally what we should do. Student Luo Feng, you don't need to thank us."
George Bedell Airy's tone was a little flat or distant.
It can be seen that his mood is somewhat complicated.
In fact, this is also true.
Not long ago.
George Bedell Airy received the letter from his son Hubert Airy, which mentioned in detail the three rounds of experiments that Xu Yun had conducted previously.
As an outstanding person who later calculated the density of the earth and the future president of the Royal Society, George Bedell Airy was very rich in both experimental experience and knowledge reserves.
Therefore, he quickly understood the experimental principles mentioned in Hubert Airy's letter and was impressed by the experimental design of "Mr. Fat Fish".
after that.
He spent another half day asking about what Xu Yun had done. After much hesitation, he finally agreed to Xu Yun's intention to cooperate.
So this morning.
He personally arrived in Cambridge with the Tatara telescope and a large number of observation records, and completed the formal delivery with Xu Yun.
But on the other hand.
Although this experiment has the mysterious "Mr. Fat Fish" as the chief designer, Xu Yun is still too young.
In addition, this matter is related to the political career of George Beadle Airy, so the current director of the Observatory in Greenwich is inevitably a little nervous and worried.
After all, my situation is not good to begin with, and now I am guaranteeing such a thing.
Once the observation fails.
He can basically think about where to dance square dance after retirement.
Compared with George Bedell Aire's complicated mood, Xu Yun is much calmer.
Just a Pluto.
When all the tools are present, calculating the trajectory is basically all you need.
Did you see the ax on his body?
This is called sincerity!
If there was another accident, he would chew this thing clean on the spot!
"Luo Feng."
Just when Xu Yun was about to look through other observation records, someone suddenly called out his name.
Xu Yun turned his head.
He found that his old acquaintance Aveline and his wife were standing about seven or eight meters away.
Sylph.
At this time, the little girl had already put on a children's version of a nun's uniform. Of course, there are no nuns in the Protestant Church. This is a special orphan costume made by the Protestant Guild for the religious orphanage, but the style refers to the color of the nun's uniform.
Other than that.
Sylph's hair and skin were also taken care of very cleanly.
Although the overall look is still a bit awkward, at least he no longer looks like a street kid.
These days, Britain is the world's hegemon, so the quality of Protestant food is also very high. It is estimated that Sylph will gradually become healthy in the near future.
After coming to Xu Yun and Lao Tang.
Sylph glanced weakly at George Beadle Ally, whose face was as dark as water, and said weakly to Xu Yun and Lao Tang:
"Mr. Luo Feng, Mr. Thomson, good morning."
Xu Yun smiled and touched her head and replied:
"Good morning, Sylph."
Lao Tang also showed a rare soft smile and nodded towards her:
"good morning."
Then Xu Yun bent down again and asked the little girl:
"How's it going, Sylph, are you still used to living in church?"
Sylph hummed softly and said tenderly:
"Mr. Luo Feng, the uncles and aunts in the church are very nice people. They don't have to work, and they don't bully people like Karls."
Xu Yun nodded slightly and touched Sylph's little head again.
He didn't know Karls, but based on Sylph's past experience, it was not difficult to judge that he should be a member of the theft gang.
Then Xu Yun glanced at the small purse that Sylph was still holding and sighed slightly.
This action was exactly the same as when they first met, indicating that she still had not completely let down her guard against the current environment.
In psychology, this is a spontaneous behavioral suggestion, just like many people tend to hold their mobile phones or wallets when they are nervous, hoping to achieve psychological comfort.
It seems that it may take a long time for Sylph to completely let down her guard.
Xu Yun then chatted with Aveline for a while, and then continued to prepare for the observation.
That night.
With the help of William Whewell, a wooden sign was erected outside the door of each major dormitory.
The content on the wooden sign is very simple, the title is a line of large characters:
[Seven days later, outside the Denark Building of Cambridge University, everyone is welcome to witness the journey of finding the ninth planet]
Below the title is a long paragraph:
[Have you ever heard of this legend? In addition to the eight known planets, there is another planet in the solar system that rotates day after day at the end of the distant and cold universe]
[There is no sound in that world, but it is waiting for a sound]
[No one could see it before, so they said it didn’t exist]
[But there are still a handful of people in the world who claim to have heard the lonely cry for help from the stars. Even though it traveled through long and distant time and space, it is still clear.]
【It seems to be saying】
【Brother Fu is fifty, I also want to eat Crazy Thursday.】
