Chapter 176 Invisible pretense is the most deadly
After listening to Li Qiwei’s remarks on the debate between liberal arts and science, almost everyone present was breathing rapidly.
In addition to Nogami Shinsuke, the Sakura Country delegation also included two teachers and students majoring in liberal arts, but at the moment they were shivering and did not dare to say anything.
Those top students who graduated from the physics major like Ishihara Jun were completely brainwashed by Li Qiwei’s pie.
He Yujie and others are very calm. They have been with the principal for so long, and they have become immune.
They firmly believe that ahead of them must be the sea of stars.
At this time, Ishihara Jun finally calmed down. Under the eyes of his teacher Nagaoka Hantaro, he said:
"Dear Mr. Li Qiwei, hello, my name is Ishihara Jun."
Ishihara Jun's attitude was very respectful, because when Li San taught Shinsuke Nogami just now, it left a deep psychological shadow on him.
With such a weak body, he had no doubt that Li San could beat ten of himself with one hand, or all at once.
The characteristic of the people of Sakura country is that they are afraid of power but not immoral.
Don't try to influence them, but just beat them to death, and they will naturally become honest.
“I have always admired your name and regarded you as my idol.”
“But there is a problem that has been bothering me.”
“There are people like you in the world. After all, there are only a few people with such extreme genius, especially physics, which is a field that values talent very much.”
"So for a physics undergraduate with ordinary qualifications like me, do you think there is any way to teach me?"
"I also want to be as good as your three major disciples."
After saying that, Ishihara Jun still looked at He Yujie and the others respectfully, as if he was really asking for advice.
Li Qiwei looked at Ishihara Jun with interest. He thought this kid was very interesting.
The other party is very self-aware and does not dare to discuss physics problems with me. Instead, he is ready to attack He Yujie and the others.
I'm afraid there's still some guidance from Nagaoka Hantaro here.
Nagaoka knew that no matter what was discussed today, Li Qiwei would be in control.
His strength is not on the same level as the people present.
Fortunately, science in Asia was just developing at this time, and all countries exchanged academic knowledge with a friendly and open attitude.
A few decades later, with Hantaro Nagaoka’s current status, he might not be qualified to meet Li Qiwei.
How big is the gap between ordinary physics professors and physics Nobel Prize winners?
Li Qiwei probably guessed Ishihara Jun’s purpose, so he smiled and said:
“Ishihara-kun, I heard Professor Nagaoka say last night that you also graduated from Tokyo Imperial University. He is his most proud student."
"He also said that you published journal papers during your undergraduate period, which was very good."
"Can you tell me what your paper is about. ”
When Jun Ishihara heard Li Qiwei praising himself, he was very proud. He raised his head and chest, pretending to be modest and said: "It's about the phenomenon of optical diffraction."
"I used a new method to prove the Poisson bright spot. The inevitability of its emergence. "
Obviously, in Ishihara Jun's eyes, his paper is very original, and in the circle of undergraduates, he is definitely considered a great person.
At this time, Li Qiwei suddenly smiled, making Ishihara Jun feel a little nervous.
“That’s such a coincidence. I have a student who also studied the diffraction of light during his undergraduate studies.”
"You two can have a friendly exchange now."
Then, Li Qiwei glanced at Xia Yuanzhen and said, "Yuanzhen, come and compete with this Mr. Ishihara."
< br>Xia Yuanxi stood up first, then nodded, and finally sat down.
In front of outsiders, Li Qiwei will always be their principal, and there must be formal respect.
"Hello, Ishihara-san, I am Xia Yuanzhen."
Ishihara Junya quickly replied: "Hello, Xia Sang."
Xia Yuanzhen said: "Ishihara Sang, I am not as good as you. I was able to publish a paper during my undergraduate period."
" When I was studying at Cambridge, my supervisor was too strict and had very high requirements for undergraduate papers. "
"My supervisor would not allow me to publish a paper if I was not innovative enough."
“So, I only have an undergraduate thesis.”
"My thesis is also about the diffraction of light. The main highlight is the consideration of the wave-particle duality of light in Young's double-slit interference experiment."
"This innovation is my My teacher, Dr. Li Qiwei, guided me to think.”
“Since light is both a wave and a particle”
“Then why does light not behave like particles in the double-slit interference experiment. "
"In other words, when light passes through a double slit, it must exhibit wave properties instead of passing through it in the form of particles, leaving two bright stripes on the screen."
"I know, you will definitely say, because this is the experimental phenomenon."
"However, from a theoretical analysis, if we can make light turn into particles at the past moment, we can do it later. That's the case."
"This is the most important content of my graduation research."
"Unfortunately, since I can't find a way to turn light into particles. So I can’t publish a paper.”
“Ashamed, I still need to study more than you, Ishihara-san.”
Jun Ishihara: Black question mark face? I was shouting crazily in my heart:
“What the hell, what wave-particle duality, are we talking about diffraction?”
“Isn’t Young’s double-slit interference experiment the simplest experiment? It has become so strange in your mouth.”
“Why didn’t you mention Poisson’s spots?”
Xia Yuanxi looked at Ishihara Jun in a daze and said tentatively: "Ishihara-san? Ishihara-san?"
"Do you think there are any shortcomings in my research? Please give me some advice."
Ishihara Jun then realized and thought, I'm just a fool to give you some advice.
He has never even heard of the wave-particle duality of light.
In fact, this cannot be said to be Ishihara Jun is a fool. Mainly at this time, basically all natural science knowledge was spread to the world from Europe.
Therefore, there will definitely be a time difference.
In addition, Li Qiwei's results are the most cutting-edge theories of physics, which are inherently obscure and difficult to understand, so they spread more slowly.
In Asia, except for the country's top scholars like Nagaoka Hantaro, who can know the general situation at the first time, the rest of the people have no access to relevant information at all.
It would be the same even if Jun Ishihara is a physics student at Tokyo Imperial University.
In the eyes of Westerners, they are all low-class students in low-class schools.
Even when Li Qiwei was in Europe, he seemed to be able to talk to everyone he met, including a few words about the theory of relativity and quantum theory.
That’s because they are all big guys in physics. Among those who deal with Li Qiwei, winning the Nobel Prize is just a basic skill.
When Li Qiwei returns to Asia, it is equivalent to the Trisolarans coming to the earth, purely dimensionally reducing the attack.
And the subject he gave Xia Yuanxi was an experiment that was highly controversial in later generations.
That is the double-slit interference experiment that is said to be illogical.
The original Young's double-slit interference experiment was a very easy-to-understand experiment.
But when later generations can master the technology of emitting single photons or electrons and consider the wave-particle duality, things get weird.
Physicists have discovered that the observer can actually affect the measurement results.
If you observe it, a single photon will behave like a particle; if you don’t observe it, a single photon will behave like a wave.
Especially the delayed photon experiment based on it has subverted even the causal relationship.
This is also the experiment that later generations of marketing accounts and clickbait parties love to brag about, with all kinds of shocks and counter-intuitiveness, physics no longer exists, etc.
In fact, it is all caused by a little knowledge. The experiment itself is not that strange.
The so-called double-slit interference experiment is not magical at all, nor is there anything weird about it, nor does it subvert cause and effect.
It’s just that ordinary people have a misunderstanding of the word [observation], and they have inherent thinking constraints on the phenomena of the quantum world.
However, if you want to understand this problem clearly, you need a lot of prerequisites.
Li Qiwei is not ready to explain to everyone here yet.
For such a big guy, he must wait until he returns to Europe before pretending.
So, when Xia Yuanzhen finished his graduation thesis, Ishihara Jun was dumbfounded.
The situation is not right as predicted in the script.
Isn’t it said that Li Qiwei’s three disciples are all very ordinary? Not even a paper has been published.
Why can’t I understand what people are saying now?
Jun Ishihara asked for help from Hantaro Nagaoka aggrievedly. The current atmosphere was a bit too embarrassing for him.
However, the shock in Hantaro Nagaoka's heart at this moment was no less than that of his students.
Because he discovered that the young man named Xia Yuanxi thought about simple but profound questions.
The physical nature contained in it made him a little frightened.
He turned his eyes to Li Qiwei and saw a faint smile on his face.
Hantaro Nagaoka was restless: Li Sang, is this your strength?
With casual guidance, students can study such profound physics problems.
I, a professor at Tokyo Imperial University, cannot explain this problem clearly.
This thought experiment is so wonderful.
At this moment, Hantaro Nagaoka already understood that he still underestimated Li Qiwei.
That man is not only awesome himself, but the students he teaches are also awesome.
It’s not that people haven’t published papers, but they just disdain to publish simple papers.
The new method of Poisson bright spots may seem to the other party to be as naive as calculating the speed of the slider.
Hantaro Nagaoka put away all thoughts of luck.
In his eyes, Li Qiwei was already the number one opponent in the scientific community of Sakura Country.
With such a powerful opponent, the future of Sakura Country's science is destined to be difficult and tortuous.
"Ishihara-kun, please step back."
"Xia Jun's research has gone beyond your knowledge."
"This experiment will not work even for me. Can’t find a reasonable solution to verify”
Then, Hantaro Nagaoka said to Li Qiwei: "Li Sang, I really envy you, you have such outstanding students."
"I really want to learn how you train your students."
< br>Li Qiwei said with a smile: "I don't have any methods, they are just aware of it."
"When they were studying in Cambridge, England, the three of them studied until 12 o'clock every night. No matter how I persuaded them, Don’t listen.”
“Good students are never taught.”
Nagaoka Hantaro curled his lips secretly, I believe you.
If you don’t teach them personally, it’s impossible for them to be that talented given their age.
Hantaro Nagaoka himself also taught students.
Of course, one can tell at a glance that Xia Yuanxi is definitely not a genius.
But I have an awesome teacher, and he is famous all over the world even if he has a slight leak under his fingernails.
Xia Yuanzhen, on the other hand, was confused the whole time. What happened? I was asked to discuss academic matters with him. Why did he stop talking?
Isn’t the wave-particle duality of light a very basic thing? It has been published for three years. Is there anyone who doesn’t know about it?
The innocent Xia Yuanzhen didn't know that he was pretending.
Invisible pretense is the most deadly.
