Sorensen ran back to the laboratory in a flash, leaving only Li Yu and Karl sitting there and continuing to eat.
Karl smiled and said: "Don't worry, he has always been like this."
Li Yu could understand his mood: "Anyone who can achieve a breakthrough after a long period of research will be so happy that he forgets to eat and sleep."
With the framework in place, it is actually very simple to build this ph theory, but it will be difficult to make waves for a while. After all, due to the limitations of the times, even many scientists themselves do not believe in atoms, let alone ions in the ionization theory.
.
So Li Yu really didn't take this matter too seriously at the moment.
The next day, he went to the University of Copenhagen as scheduled.
When "Columbia" is mentioned in later generations, most people's first impression is definitely Columbia University, but in fact, there are two brothers named "Brother": the University of Copenhagen and the University of Copenhagen.
There are many criteria for judging universities. If we just talk about the number of Nobel Prizes, Columbia University is certainly stronger. It ranks fifth among universities in the world, with 96 Nobel Prizes.
The University of Göttingen ranks 15th, with 45 Nobel Prizes;
The University of Copenhagen ranks 17th, with 39 Nobel Prizes.
So the "brothers" are not small roles.
There is currently no bronze statue of the famous Little Mermaid in Denmark. It was actually a gift from the Carlsberg Foundation in 1909.
Since then, the statue's head, arms and other parts have been sawed off many times. In 2003, it was blown into the water with explosives and was seriously damaged when it was salvaged.
In 2017, someone splashed blue and white paint on her; someone else splashed red paint on her...
There are countless such things, especially all kinds of graffiti. There are too many excuses for some graffiti. There are endless excuses for some graffiti, such as nationalism, religion, or extreme animal protectors protesting against whaling. It is impossible to enumerate.
Some people have even labeled the bronze statue of The Little Mermaid a racist label. For example, during the Black Lives Matter movement, some black people opposed any historical statues because they felt that these historical figures had been victims of racist oppression by slave traders and colonialists.
played a role.
Although it's hard to understand how a fairy tale about the Little Mermaid could be racist.
And the poor little mermaid didn't know that she would bear so much "unbearable weight".
When Li Yu came to the University of Copenhagen, Paterson himself, an academician of the Royal Danish Academy of Sciences and president of the University of Copenhagen and a professor of mathematics, brought with him the physics and oceanography scholar Knuzen, the biology lecturer August Crowe, the ecologist Warming and others.
Let's welcome Li Yu together.
This treatment is quite high.
Among them, Patterson is not young, and he himself is doing graph theory research. This thing has been of interest to many mathematicians in Europe since Euler pioneered the study of the Seven Bridges problem.
Crowe would win the Nobel Prize in 1920.
Paterson also values Li Yu very highly. After all, he is a scholar with many first-class achievements. It is not an exaggeration to say that he is a top scientific master in the world today.
But they obviously don't know that Li Yu will become more and more terrifying in the future.
"Dear Academician Li Yu, it's really exciting to meet you," Patterson said.
He also used the title of Foreign Academician of the Royal Society.
Li Yu has been called an academician by two people one after another, and he is really not used to it.
Fortunately, the other party was also an academician, so Li Yu said: "Hello, Academician Paterson."
Paterson said: "We at the University of Copenhagen have always respected natural philosophy, and we have made the teachers and students of the Faculty of Science look forward to your speech early."
Li Yu was a little confused as to why he wanted to give a speech again, so he said: "Actually, the content is all in the book, just simple exchanges."
Patterson said: "No problem, you can say whatever you want."
Crowe said: "Everyone is not only interested in your academic achievements, but also interested in the East, so don't refuse this speech no matter what."
Li Yu felt that the kindness was hard to refuse, so he agreed.
The department structure of the University of Copenhagen is very similar to that of the University of Paris where I visited last time. Both places natural sciences in specialized faculties of science.
Patterson happily took Li Yu to the auditorium of the School of Science. It is not easy to recruit big names in science nowadays. Most of them have some kind of position, or are old and unwilling to move around too much. Young people like Li Yu
It's rare to see someone with a lot of energy.
Paterson even said: "I have carefully studied your chaos theory and game theory, and it seems like you have created a new mathematical path. And seeing that you are so young, it instantly reminds me of Mr. Abel who visited you back then."
Li Yu was very familiar with Abel, so he asked: "Is he from Norway? He has also been to the University of Copenhagen?"
Paterson said: "No, but a senior at the university, Professor Hansting, took him in, but he quickly left for Paris resolutely."
The reason why Abel went to France at that time was because France had been a center of mathematics for a long time and produced a large number of talented people in mathematics. Later, it was slowly overtaken by Germany.
Li Yu sighed: "It's a pity that there was a mathematical genius of similar age in Paris at the same time, Galois."
These two men laid the foundation for the group theory of modern mathematics in their short lives, but they were both only in their twenties when they died.
Abel was very poor and died of tuberculosis at the age of 26.
Three years later, Galois fought a duel with an officer for what others called "a coquettish woman in a low-level inn", and he was only 21 years old.
I really can't imagine what would have happened if they had lived a few more decades.
There is no mathematics prize in the Nobel Prize. The highest mathematics award since then is the Fields Medal, but it is only awarded to mathematicians who are no more than 40 years old. Perhaps it is because they are afraid that another young pearl will be lost.
But it seems that most scientists or artists achieve their greatest achievements before the age of forty.
Just like Zhang Ailing said, "You have to become famous early."
Patterson came to the podium and introduced Li Yu first. In fact, he didn't need any introduction. When the yellow-skinned and dark-eyed Li Yu appeared, the audience was already filled with exclamations of surprise.
"Oh my God, he's like a student our age!"
"How on earth did he achieve such high achievements in physics, mathematics, and astronomy at such a young age!"
Paterson stretched out his hand and pressed down: "Everyone, be quiet! It is not easy to invite Academician Li Yu, a hot new star in today's scientific world. The Royal Academy of Sciences and the Carlsberg Foundation jointly won this opportunity. Everyone must cherish it.
From him, I learned the path to seek truth..."
After hearing this, Li Yu thought to himself, in fact, it's not that difficult for me to invite him. He can come over with a little persuasion!
After Paterson spoke for a few minutes, he said to Li Yu: "Academician Li Yu, please come and speak."
Li Yu walked to the stage and really didn't know what to say, so he said casually: "This time it comes quite suddenly, and I actually didn't make any preparations. Otherwise, everyone would ask questions to find an introduction."
Li Yu scanned the people below, and there were not many of them. The enrollment scale of universities nowadays is generally not large.
He quickly found Bohr, because his head was really big and very obvious.
"Bohr, what do you want to say?" Li Yu asked.
In fact, he had been thinking about it for a long time and called Bohr, one of the three giants of quantum mechanics, his "classmate", which was really a bit awkward.
Bohr was a little surprised. Although he wanted to speak, he was only a freshman and felt that it was not his turn yet.
Li Yu's sudden question made him feel at a loss for a moment, "Ah...I..."
Li Yu smiled and said: "It doesn't matter, just ask."
Bohr said: "I, I am thinking about what formation to use in the afternoon football match. Academician, do you also like football?"
Li Yu was also confused by the question, "Football? Of course I like it..."
Bohr continued: "We will play a game with the seminary in the afternoon. You can also join us! Anyway, we are about the same age."
"Okay... okay..." Li Yu didn't know how to answer the question.
The students in the back burst into laughter, and someone said:
"The seminary is very strong and it will be difficult for us to win, so let's not think about it."
"Let you ask, why does it involve football?"
Bohr said: "Academician Li Yu asked me to ask casually."
A person next to Bohr suddenly said: "Brother, we will definitely win, don't worry about this problem. Now that I have finally met Mr. Li Yu, try to ask some professional questions."
Li Yu suddenly realized, I felt dizzy, I actually admitted that I was wrong!
The "Bohr" identified at the beginning was actually the younger brother of the famous quantum mechanics giant Niels Bohr. His name was Harnald Bohr.
The two brothers were about the same age and looked very similar, so Li Yu suddenly found the wrong person.
But Bohr's younger brother was not simple either. He was even more talented than his elder brother when he was young, and he later became a mathematician.
Moreover, the two brothers loved football since childhood and even almost became professional athletes.
In particular, his younger brother Harnad Bohr represented the Danish football team and won the football runner-up in the 1908 Olympic Games.
The two brothers are the best in mathematics and mathematics in the football world, and the best in football in the world of mathematics and physics!
"Really," said Bohr, "can I ask a question?"
Li Yu was a little embarrassed just now, so he said: "Of course."
Bohr said: "I have read many academicians' papers on the derivation of blackbody radiation. If this is true, then it means that the unit of energy must be extremely small to be in the state of parts. This also confirms the existence of atoms from the side.
Also consider the previous experiment of Professor Thomson of the Cavendish Laboratory of Cambridge University in the UK. There are electrons in atoms. What state are they in? How are the charges distributed?"
Li Yu could not have imagined that Bohr would start thinking about such advanced questions just after entering the University of Copenhagen, but the questions he asked were indeed too big, so he replied: "What you proposed is exactly the direction of the future development of physics, but I have to regret it a little bit."
Let me tell you, this question is difficult to answer because it involves experimental demonstration, otherwise anything proposed at this moment will only be a hypothesis."
Bohr asked: "According to the academician's paper, if atoms exist, their scale is extremely small. How can such an experiment be done?"
Li Yu said: "Good question! But the physics of atoms is an extremely precise science. This level of precision is like measuring the distance from London to St. Petersburg with only a hair difference."
Bohr was surprised: "Is this possible?"
Li Yu said: "Of course you can, otherwise how can you face everyone's doubts?"
After the development of quantum mechanics, it has become a science that is extremely precise in experiments. Many experiments are so sophisticated that ordinary people cannot even imagine it. It is an epic achievement for mankind to explore the microscopic world.
