Chapter 294 Einstein has left the group chat (9.8k begging for monthly votes!!!!)
On the dining table.
Mai was secretly eating boiled seabass. His whole body was numbed by the peppercorns and he was a bit doubtful about life. He was so confused that he seemed to be speaking in Parseltongue.
After hearing what Xu Yun said, he quickly put down his chopsticks, quickly picked up the eggnog and took a sip to suppress the taste.
After doing this, he began to think about Xu Yun's problem.
"Future plans."
I saw him gently scratching his head, looking at Xu Yun and saying:
"Mr. Luo Feng, my original plan was to get a scholarship first, and then try to stay in school as a teaching assistant after graduation to gain some experience."
"When I have enough qualifications, I will go back to Scotland and become a professor. I will pay off my family's debts within three or four years, and then I will see if there is a chance to start a family or something."
Lao Tang, who was sitting opposite him, noticed a word keenly and couldn't help but raise his eyelids and glance at him:
"Original plan? Now you have changed your mind?"
"."
Xiaomai nodded slightly and was silent for a few seconds, with a trace of confusion in his eyes:
“It’s not really a change of mind, it’s just that I don’t know what to choose.”
"Mr. Faraday actually came to me these days and proposed the idea of accepting me as a graduate student."
“It takes time to study for graduate school—it can take as little as two years, or as long as four years. In this way, it will be difficult to pay off my family’s debt.”
Xu Yun glanced at him lightly.
Although Mai's father, John Clark Maxwell, was a lawyer, he almost spent all his savings to treat Mai's mother's tuberculosis more than ten years ago.
But unfortunately, Mai's mother eventually passed away.
Later, his father, Lao Mai, suffered another huge loss in his flour business and owed a large sum of money.
Xu Yun didn't know the specific amount, but historically it took Wheat eight full years to help pay off the money.
Therefore, Wheat’s wallet has not been very generous all this time.
The core reason why Wheat returned to Scotland to teach at Marishal College in 1856 was that they gave him too much
At that time, Cambridge's salary for wheat was 4.5 pounds a week, which was a monthly salary of 18 pounds, which is equivalent to a monthly salary of about 16,000 in today's purchasing power.
The University of Glasgow offers a weekly salary of £5 during the probationary period and £7 during the regular period.
And Marishal College
In one fell swoop, I was offered a weekly salary of 12 pounds, which is 48 pounds a month.
This is just like how China, the Middle East, and the Eagles League spent a lot of money to poach people in later generations. They relied on money to poach more people.
Some people in later generations thought that it was a waste of wheat's four years at Marischer College, but they ignored that wheat was in urgent need of money.
Scientists are also human beings, and they also need to be careful.
If it comes to the national level, it may still be supported by awareness and belief, but personal careers are undoubtedly much more realistic.
Then looking at the confused Mai, Xu Yun put his fork on the table and asked:
"Maxwell, if you didn't have to worry about debt, would you like to go to graduate school?"
"Of course I do."
Xiaomai answered in the affirmative without hesitation, and his eyes even lit up:
"I originally thought I would continue on the path of pure theoretical mathematics in this life, but it was only now that I discovered that the world of electromagnetism is countless times more mysterious and vast than theoretical mathematics!"
"For example, Professor Gauss gave me several volumes of manuscripts more than a week ago, which describe a system beyond Euclidean geometry. I found that it is equally important for electromagnetic research."
".Wait a moment, Maxwell-san!"
Before Xiaomai finished speaking, Riemann suddenly interrupted him and asked solemnly:
"Classmate Maxwell, you said that Mr. Gauss gave you several volumes of manuscripts, which record mathematical systems other than Euclidean geometry?"
Xiaomai nodded, unaware of Riemann's subtle expression, but said to himself:
"When I was looking for Conan's star, didn't I discover the companion star? I did Professor Gauss a small favor."
"Later, he chatted with me several times and gave me several volumes of manuscripts a few days ago."
“One of the manuscripts records Professor Gauss’s speculation about this system—at first he named it starry sky geometry, but later changed it to non-Euclidean geometry.”
"In my opinion, Professor Gauss's manuscript is much more complete than Mr. Lobachevsky's theory, but it is a pity that it has not been made public"
After listening to his narration quietly, Riemann was silent for a long time, and suddenly sighed with emotion:
"Classmate Maxwell, from now on, I may call you junior brother."
Wheat:
".?"
Seeing that Mai was a little confused, Riemann took the initiative to explain:
"Classmate Maxwell, you may not know something. The concept of non-Euclidean geometry is so impactful that it can easily be refuted by public opinion."
"Therefore, the teacher has not announced his results to the outside world."
"Although there are sporadic people who have heard that the teacher is conducting research on non-Euclidean geometry, only direct disciples like us have actually seen the manuscript, and there are no more than five of them."
After saying this, Riemann looked at Xiaomai with a closer look:
"Teacher's health has not been very good in recent years. After you graduate from the undergraduate program, I'm afraid I won't have the energy to take you to graduate school."
"But since he handed this manuscript to you, in a sense, I can indeed call you junior brother."
"."
After listening to Riemann's words, Xiaomai's face clearly showed a hint of astonishment.
What's going on?
When Gauss gave him these manuscripts, his original words were clearly "some trivial research results."
How did it come to Riemann's mouth that it was a top-secret document that only his disciples could read?
He was a student in the Department of Mathematics at Cambridge University, and he only chatted and laughed with Gauss a few times. How could he become a disciple of a professor at the University of Göttingen?
Why don't you talk to Professor Gauss and ask him to hire someone else?
Xiaomai looked at Riemann in confusion, unaware that Xu Yun beside him had already fallen into a greater shock than them.
Oh my god!
Non-Euclidean geometry!
Gauss actually gave this thing to Xiaomai? ? ?
As everyone knows.
In the long scientific history of mankind, many far-reaching works have been produced.
For example, in the East there are "Zhou Bi Suan Jing" and "Nine Chapters of Arithmetic".
For example, in the West there are "Mathematical Principles of Natural Philosophy", "Spiral" and so on.
And if we talk about the book with the longest plan for establishing spatial order, then the "Elements of Geometry" should undoubtedly be recommended first.
This book established the famous Euclidean geometry system and is a cornerstone work in the history of mathematics.
Euclidean geometry has dominated the mathematical world for two thousand years after it was proposed, and no one can shake its authority.
But on the other hand.
Euclidean geometry is invincible in terms of system, but some details have always been controversial.
Such as its fifth axiom.
The content of this axiom is as follows:
A straight line intersects two other straight lines in the same plane. If the sum of the two interior angles on a certain side is less than two right angles, then the two straight lines will intersect on this side after being infinitely extended.
Because the fifth axiom is lengthy, it is not obvious.
So some mathematicians came up with an idea:
Can the fifth axiom not be regarded as an axiom, but as a theorem?
Can we rely on other axioms to prove the fifth axiom?
This is the discussion of the "parallel line theory" that has been debated for more than two thousand years in the history of geometry development.
The Swiss geometer and mathematician Lambert, the famous French mathematicians Legendre and Lagrange, and others have all spent a lot of energy on this issue.
Unfortunately, they were unsuccessful.
This problem is like that of Paper Man’s Wife.
Ruthlessly consuming the tissues of otakus without giving them any substantive love.
This situation lasted until the beginning of the 19th century, and finally someone stood up:
He is the Russian mathematician Lobachevsky.
His ideas were completely different from those of his predecessors. He inherited the fine tradition of Mao Xiong and boldly thought about the opposite formulation of this problem:
Is it possible that there is no proof of the fifth postulate?
So.
He then conducted research along this line of thought and set out to find a solution to the unprovable fifth postulate.
The first thing he did was to deny the fifth postulate.
That is to say, it is assumed that "through a point outside the straight line on the plane, at least two straight lines can be drawn that do not intersect with the known straight line."
Then use this negative proposition and other axioms and postulates to form a new axiom system, and start logical deduction from it.
Finally, during the deduction process, he obtained a series of strange data.
But here's the surprise.
After Barochevsky's careful examination, no logical contradiction was found between them.
So Lobachevsky boldly asserted:
This new axiom system, "without any contradiction in the results," can constitute a new geometry.
Its logical completeness and rigor are comparable to Euclidean geometry, and the existence of this new geometry without contradiction is a refutation of the provability of the fifth postulate.
That is, the logical proof of the unprovability of the fifth postulate.
Since the prototype and analogue of the new geometry in the real world has not yet been found, Lobachevsky cautiously called this new geometry "imaginary geometry."
Lobachevsky chose to make this theory public in 1826, then
He was sprayed by public opinion into the heart of a neon man, with holes everywhere, and his body was completely damaged.
Because this theory really challenged the cognition at the time, it was as outrageous as a later banana saying that it would explode in a week.
It was not until 1866, 12 years after Lobachevsky's death, that non-Euclidean geometry was successfully overturned.
Lobachevsky's experience may seem a bit like wheat at first glance, but in fact he is much worse than wheat:
Wheat later served as the first director of the Cavendish Laboratory, but Lobachevsky suffered a full thirty years of suppression from many parties.
Although he entered the German Academy of Sciences, the allowance was only received once in the name of condolences in the month after his death, which is sad.
And compared to Lobachevsky, there is a big guy who discovered non-Euclidean geometry, which is much more of a thief.
He is Gauss.
Gauss discovered non-Euclidean geometry many years before Lobachevsky, and the relevant theoretical system was much more complete than Lobachevsky's.
But Gauss was very aware of the impact this new system would have, so his cautious thoughts took over again and he did not choose to make his theory public.
It was not until Gauss's death that these contents were discovered in the manuscript.
By the way.
Along with these manuscripts, more than a dozen methods of algebraic proof were discovered
The originals of these manuscripts are now in the Gauss Museum in Dransfeld, 10 kilometers southwest of Göttingen, and scanned copies can be found and downloaded on the official website of the University of Göttingen.
However, what caused Xu Yun's complicated mood was not that Gauss gave the manuscripts to Xiaomai, but the subsequent impact these manuscripts would have.
Mentioned previously.
Mavericks in this timeline independently completed the establishment of calculus, and Leibniz lost an honor that will go down in history.
After becoming famous, Mavericks worked at Cambridge University as Professor Lucas for decades. Therefore, Cambridge University's foundation in calculus is naturally the deepest in Europe.
At the same time.
As the ultimate pervert who can derive Maxwell's equations and one of the future leaders of the Department of Mathematics, Wheat's achievements in differential topological manifolds are naturally not low.
Friends who have studied big things and advanced mathematics in later generations should all know this.
Differential manifold plus non-Euclidean geometry, this is Riemannian geometry theory
Don't worry, it's not over yet.
To know.
Xu Yun had already figured out electromagnetic waves during the opening ceremony.
Coupled with the derived wave equation, it can be said that the core of electrodynamics has been almost completed by him.
Earlier, he also wrote to Mavericks to point out the errors in the absolute view of time and space.
Oh right.
There is also the rotating mirror method that Xu Yun optimized when tinkering with the speed of light distance measurement. It is estimated that the Michelson-Morley experiment can start seven or eight years earlier.
That is to say.
When Xiaomai was about forty years old, something like this would appear on his technical column:
Electrodynamics + Riemannian geometry + differential geometry + photoelectric effect + the first dark cloud are all working together
As everyone knows.
Using the constant c invariant and performing logical derivation, we get the variable space-time.
That is to say
When Xiaomai was forty years old, he already had the conditions, tools, and ideas to derive the theory of relativity.
It would be hard to tell if it were anyone else, but this guy is Maxwell
He couldn't deduce the theory of relativity before he was forty-five years old, so Xu Yun ate the ax on the spot!
all in all.
What Xu Yun did originally was equivalent to building a mountain of gunpowder. It looked amazing, but without a fire source, it was just a pile of powder.
The manuscript that Gauss threw to Mai turned out to be a match.
Gauss seems to be just a slight throw, but what are the consequences?
Riemann can still be supported by the Riemann Hypothesis, but I guess I will be scolded.
Of course.
With Lao Ai's ability, and with predecessors like Xiaomai setting the stage, he might be able to create even more amazing results.
At worst, if I can see my old love in the future, try to make sure his brain is not sliced into pieces to make up for it
Think of this.
Xu Yun couldn't help but take a deep breath, raised his head, and said to Xiaomai:
"Classmate Maxwell, you must study the manuscript that Professor Gauss gave you carefully. It may bring you some unexpected gains."
"As for your studies, I still think you should study with Mr. Faraday. There may be other ways to solve the debt."
After saying that, he lightly swept around the dining table.
Since there were other people present today, some of his words were not appropriate to say.
As the great-great-grandson of later generations of wheat.
Xu Yun didn't go into detail about Xiaomai's life experience, at least he knew all the key points.
Therefore, he had been preparing for his life after leaving Maimai a long time ago.
After all, the core of the mission this time is to change the fate of Mai and Laotang.
Now that Laotang's fate has changed, there are two patches that must be made for Wheat's fate.
The first one is naturally wheat’s stomach disease.
The cause of Mai Mai's untimely death was stomach cancer. His poor eating habits caused him to suffer from extremely serious stomach problems, and he eventually died young at the age of 48.
There are no specific drugs for gastric cancer these days, but Xiaomai is only 20 years old now. If he maintains good eating habits, there is basically no chance of recurrence of gastric cancer.
In addition, the second patch is Wheat’s wallet.
Xu Yun has arranged some backup plans for Xiaomai, but these backup plans may not allow Xiaomai to become as wealthy as Cavendish.
But at least it allows him to do academic work with peace of mind, easily afford some experimental losses, and have no worries about food and clothing for the rest of his life.
Then Xu Yun stood up.
I went back to my bed to find a blank notebook, and returned to my seat with paper and pen:
"Come on, Maxwell, write down your life plan. Don't make it too long."
Xiaomai took the paper and pen, pondered for a moment, and wrote a sentence on it:
[Go to graduate school after graduation, with the goal of staying in school to teach, and becoming a nominee for the Copley Medal] - James Clerk Maxwell.
Copley Medal.
This is a medal established by the Royal Academy of Sciences. Before the Nobel Prize was established, it was tied with the Academy Essay Award of the Gallic Academy of Sciences as the two highest honors in the world.
Compared with Riemann's goal, Wheat's expectations are obviously higher.
But if we compare the two according to their status in life, it was Riemann who milked him in the opposite direction:
Riemann became famous in one battle four years later, but Wheat went up and down after graduation.
It is indeed a pity that a master who derived Maxwell's equations did not receive the Copley Medal.
Then Xu Yun took the note and thought about it, handed it to Hubert Airy, and said:
"Classmate Airy, it's your turn next."
Ai Li took the note, opened a page, and wrote a paragraph neatly and generously.
After he finishes writing.
Xu Yun took the note and read it aloud:
"Graduate successfully and succeed your father as director of the Royal Observatory?"
Ai Li hummed at Xu Yun, his expression looked very relaxed, and he said with a smile:
"I grew up at the Royal Observatory since I was a child. I have a deep affection for it. It can even be said to be my second home."
"So my plan is very simple, that is, to become the real owner of that family and be able to help my father solve some problems."
Xu Yun nodded slightly.
Hubert Airy's goals were neither high nor low, nothing particularly impressive.
To use an analogy from later generations, it is probably equivalent to a top student from Shuimu University wanting to become the director of the Purple Mountain Observatory.
Hubert Airy obviously has enough potential, but it is unclear whether Xu Yun has realized this dream in history - he is indeed not familiar with Hubert Airy.
If it weren't for the surname and the fact that Airy was isolated when they met, Xu Yun wouldn't have thought about George Bedell Airy at all.
However, considering that George Bedell Airy later became the president of the Royal Society, the possibility of Hubert Airy realizing his expectations should not be low.
Then Xu Yun looked around again, walked a few steps to the side, and handed the notebook to Kirchhoff.
He was not that close to the German, so he was given a slight ranking advantage:
Being the fourth person after Riemann, Wheat and Hubert Airy should not give him the thought of being looked down upon.
I saw this electrical engineering guru who had yet to grow a beard take the notebook, try his pen on the blank area, and quickly started writing.
Less than half a minute later.
Kirchhoff handed the notebook back to Xu Yun.
Xu Yun took it and glanced at it a few times, then read it with some difficulty - because Kirchhoff wrote in German.
The written expressions of German are somewhat similar to English. In fact, most of them are the same as English letters, and the difference is not as big as spoken language.
But the problem is
Germans like to use cursive writing, which looks like prescriptions written by later generations of doctors, which adds a lot of difficulty.
Xu Yun's translation template did not have a built-in fine-tuning function, so it took him some effort to read the content clearly.
"Become as great a physicist as your teacher, William Weber, then."
As he read, Xu Yun's expression suddenly froze.
He glanced at Kirchhoff, who was sitting upright, and continued reading:
".Marry a wife who is over 165cm tall, has fair skin and is beautiful. There should be no freckles on her face. She is innocent and has four children for nothing."
After hearing this, everyone at the scene looked at Kirchhoff and immediately felt something wrong:
"."
Even Tian Haosuo, a shy boy who kept his head down, looked at Kirchhoff curiously.
I didn't expect you to be this kind of person.jpg.
Fortunately, this electrical giant is quite handsome, otherwise in future generations, he would be labeled as a common man in no time.
But then again.
Perhaps it is also the inertia of history.
In the original timeline.
Kirchhoff did write such a passage in a letter to Bunsen, and they actually gave birth to four children.
By the way.
The fourth grandson of Kirchhoff's fourth son became a member of Arsenal's board of directors at the age of forty-four
How to say it.
Some things are indeed quite metaphysical, so I won’t accept them.
After Kirchhoff finished writing his notebook.
Xu Yun glanced at the remaining three people, Lao Tang, Tian Haosuo and Aveline.
Think for a moment.
He chose to put the notebook in front of Tian Haosuo and said:
"Brother Haosuo, it's your turn."
Tian Haosuo was a little surprised by Xu Yun's behavior and pointed at himself in surprise:
"Ah? Brother Luo Feng, do I want to write too?"
Xu Yun nodded, put the pen in front of him with a click:
"Please."
Tian Haosuo first quickly glanced at everyone on the table, and his shy character made his face turn red again.
But in the end he picked up the pen and started writing in the notebook seriously.
A full five minutes later.
He carefully put down the pen and handed the notebook back to Xu Yun with both hands:
"I've written it, Brother Luo Feng."
Xu Yun also took the notebook with both hands and began to read it slowly.
Tian Hao also writes in English. After all, he grew up in London since he was a child, otherwise he would not be able to keep up with the teaching progress in Cambridge.
However, compared to others, Tian Haosuo's handwriting is still a little skewed:
"Become a wealthy businessman, save money to cure my mother's rheumatism, move out of the slums, and not be bullied in the future, and live in a house that does not leak."
"If I can have a child, I hope he can also enter Cambridge University and return to the East with my ashes after my death."
"."
Xu Yun slowly finished reading Tian Haosuo's notes and sighed leisurely.
The content of the note was a bit heavy, so the expressions of everyone present were solemn, but there was not much touch in their eyes.
Only Sylph raised her head and gave Tian Haosuo a weak look.
Xu Yun was not surprised by everyone's reaction.
After all, except for Tian Haosuo himself, basically all the other adults at the scene did not experience too miserable childhood:
For example, Lao Tang's family is a farmer in Scotland, and his family is quite wealthy. When he was ten years old, he was able to attend Douglas University's preparatory program with full funding.
Hubert Airy was much the same.
Although his father's reputation has been ups and downs, his position as director of the Royal Observatory has never been changed, and his living conditions are still very favorable.
Riemann's father is a Lutheran pastor. Pastors may not be rich these days, but they are certainly not poor.
Kirchhoff's grandfather was a professor at the University of Heidelberg, and his father ran a carriage shop, which had nothing to do with poverty.
Not to mention Aveline.
Although a lot of people died in her family, she did inherit the Aiscu family’s dividends from the ketchup
Really rich woman.
So on site today.
Apart from Xu Yun, the only person who can really empathize with Tian Hao is Sylph, an orphan who escaped from the den of thieves.
Think of this.
Xu Yun sighed again.
Of all the people who have written today, Tian Haosuo is the only one who has not mentioned academic goals.
His thoughts are pure:
Graduate, make money, move.
But again.
He was also the person who touched Xu Yun the most.
His expectations were realistic and humble.
His requirement for the house is not that it is spacious and luxurious, but just a waterproof one.
Isn’t this the thought of many people in later generations?
Don't know why.
Looking at the crooked words on the note, Xu Yun suddenly thought of Du Fu's poem:
There are tens of millions of mansions in Ande, which can shelter the poor people all over the world and make them happy. They are as safe as a mountain even in wind and rain.
Then he shook his head, temporarily dispelling the heaviness in his heart.
He walked up to Lao Tang with his notebook and said to him:
"Mr. Thomson, it's your turn."
Lao Tang has always been a very open-minded person. After taking the paper and pen, he nodded and started writing immediately.
In less than half a minute, he put down his pen:
"Okay."
Xu Yun picked up the notebook and saw that the content on it was very short:
"Coned a Lord, became President of the Royal Society, occupying at least two pages in the Chronicle."
Well, this is very old soup.
The personalities of Lao Tang and Xiao Mai are two extremes. Xiao Xiao is shy and honest, while Lao Tang is relatively flamboyant and ambitious.
He never hides his pursuit of power and is fearless even if he competes with others.
In the Apostolic Society, he competed with Rossetti for power, and in the school, he ran for president of the student union with Ellis. Even though he knew that he would drop out of school if he failed in the election, he did not flinch.
The life plan he wrote is actually equivalent to an enlarged version of the achievements in school.
Now that he has become the president of the Cambridge University Student Union, he is indeed qualified to say what he said above.
On the other hand.
The content written by Lao Tang is also the plan that is most consistent with his own direction in the real timeline among everyone currently.
in the original history.
Lao Tang was indeed knighted in 1866 and promoted to Lord Kelvin in 1892.
He also served as President of the Royal Society from 1890 to 1895. The achievement of the photothermodynamic temperature scale is enough for him to occupy two pages in the chronicle.
In addition, Lao Tang lived to the age of 83 and had many children and grandchildren.
Finally, he passed away peacefully on December 17, 1907. After his death, he was buried in Westminster Abbey, enjoying the highest level of funeral treatment in the UK.
There is no doubt about it.
Lao Tang's life was quite successful and brilliant, and could even be said to be a textbook template.
And in this copy now.
Old Tang's only "stain" was taken away by Earl Ellis, and his name could be cleared for the rest of his life.
Hiss. This guy is the protagonist, right?
Then Xu Yun opened another page in the notebook and walked to.
Evelyn's side.
He gently placed the notebook in front of Aveline and said:
"It's your turn, Aveline-san."
Aveline looked up at him, took the paper and pen equally generously, and started writing on it.
Perhaps because she knew the manuscript carefully, Aveline wrote a little faster than Lao Tang.
After just a few moments.
She handed the notebook she had written to Xu Yun and said:
"Okay."
Xu Yun nodded towards her and took the notebook.
After seeing the content clearly, he was stunned.
I saw a sentence written on the page of the notebook:
[Go to the East once in ten years and visit Mr. Fatty’s hometown of Hujian]. (End of chapter)
