1900: A physics genius wandering around Europe

Chapter 176: Invisible Pretense, the Most Deadly

After listening to Li Qiwei's remarks on the debate between arts and sciences, almost everyone present breathed rapidly.

In addition to Shinsuke Nogami, the Sakura Country delegation also included two teachers and students majoring in liberal arts, but at this moment they were trembling and dared not say much.

Top students who graduated with a degree in physics like Jun Ishihara were completely brainwashed by Li Qiwei's big promise.

He Yujie and his friends were very calm. After being with the principal for so long, they had become immune to it.

They firmly believe that there must be a sea of ​​stars ahead of them.

At this time, Ishihara Jun finally calmed down. At the signal from his teacher Nagaoka Hantaro, he spoke:
"Dear Mr. Li Qiwei, hello, my name is Jun Ishihara."

Jun Ishihara's attitude was very respectful, because when Li San just taught Nogami Shinsuke a lesson, he was left with a deep psychological trauma.

With his weak body, he had no doubt that Li San could beat ten of him with one hand, or all at the same time.

The characteristic of the Sakura people is that they fear power but not virtue.

Never try to persuade them, but just beat them to death and they will naturally behave themselves.

"I have long admired your name and regard you as my idol."

“But there is one question that has been bothering me.”

"After all, there are only a few people in the world who are extremely talented like you. Especially in physics, which is a field that values ​​talent very much."

"So for a physics undergraduate like me with average qualifications, do you think there is any way you can teach me?"

"I also want to be as good as your three disciples."

After saying this, Ishihara Jun still looked at He Yujie and the other two respectfully, as if he was really seeking advice.

Li Qiwei looked at Ishihara Jun with interest. He thought this guy was very interesting.

The other party was very self-aware and did not dare to discuss physics problems with him. Instead, he prepared to attack He Yujie and others.

I'm afraid that this was also due to the guidance of Hantaro Nagaoka.

Nagaoka knew that no matter what was discussed today, Li Qiwei would be in control of the whole situation.

His strength is simply not on the same level as those present.

Fortunately, science in Asia was just developing at that time, and all countries were exchanging academic ideas with a friendly and open attitude.

If a few decades later, with Nagaoka Hantaro's current status, he probably wouldn't be qualified to meet Li Qiwei.

How big is the gap between an ordinary physics professor and a Nobel Prize winner in physics?

Li Qiwei probably guessed Ishihara Jun's purpose, so he smiled and said:

"Ishihara-kun, I heard from Professor Nagaoka last night that you also graduated from Tokyo Imperial University and were his most proud student."

“He also said that you published journal papers during your undergraduate studies, which is very outstanding.”

"Can you tell me what your thesis is about?"

When Ishihara heard Li Qiwei praising him, he felt very proud. He raised his head and chest and said modestly, "It's about the optical diffraction phenomenon."

"I used a new method to prove the inevitability of the appearance of Poisson bright spots."

Obviously, in Ishihara Jun's eyes, his thesis is very original and he is definitely considered a genius among undergraduates.

At this moment, Li Qiwei suddenly smiled, which made Ishihara Jun feel a little nervous.

"That's a coincidence. I have a student who also studied the diffraction of light during his undergraduate studies."

"You two can have a friendly exchange right now."

Then, Li Qiwei glanced at Xia Yuanzhen and said, "Yuanzhen, come and have a discussion with Mr. Ishihara."

Xia Yuanzhen first stood up, then nodded, and finally sat down.

In front of outsiders, Li Qiwei will always be their principal and formal respect must be shown.

"Hello, Mr. Ishihara, I'm Xia Yuanzhen."

Ishihara Junya quickly replied: "Hello, Xia-san."

Xia Yuanzhen said: "Mr. Ishihara, I am not as good as you. I can publish papers during my undergraduate studies."

"When I was studying in Cambridge, the tutors there were too strict and had very high requirements for undergraduate papers."

“If it’s not innovative enough, my supervisor won’t allow me to publish a paper.”

“So, all I have is my undergraduate thesis.”

"My thesis is also about the diffraction of light. The most important highlight is to consider the wave-particle duality of light in Young's double-slit interference experiment."

"This innovation was guided by my teacher, Dr. Li Qiwei."

"Since light is both a wave and a particle."

"Then why doesn't light exhibit particle properties in the double-slit interference experiment?"

"In other words, why does light behave as a wave when it passes through the double slits, rather than passing through as a particle and leaving two bright stripes on the screen?"

"I know, you will definitely say that, because that's what the experimental phenomenon is."

"But theoretically, if we can turn light into particles in the past instant, we can achieve the latter."

“This is the most important part of my graduate research.”

"Unfortunately, I couldn't publish my paper because I couldn't find a way to turn light into particles."

"I'm ashamed. Compared to you, Ishihara-san, I still need to learn more."

Jun Ishihara: Black question mark face? Crazy screaming 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? How come it becomes so strange in your mouth?"

"Why don't you mention Poisson's bright spots?"

Xia Yuanzhen looked at Ishihara Jun in a daze and asked tentatively, "Ishihara-san? Ishihara-san?"

"Do you think there are any shortcomings in my research? Please give me some advice."

Ishihara Jun finally reacted and thought, what the hell is this? I'm not giving you any advice, why are you giving me any advice?

He had never even heard of the wave-particle duality of light.

Actually, this does not mean that Ishihara Jun is stupid. The main reason is that at that time, almost all natural science knowledge was spread to the world from Europe.

Therefore, there will definitely be a time lag.

In addition, Li Qiwei's achievements are all cutting-edge theories in physics, which are obscure and difficult to understand, so they spread even more slowly.

In Asia, except for a country's top scholars like Hantaro Nagaoka who can know the general situation at the first time, other people have no access to relevant information at all.

This would be the same even if Jun Ishihara was a physics student at the Imperial University of Tokyo.

In the eyes of Westerners, they are all mediocre students from mediocre schools.

Although when Li Qiwei was in Europe, he seemed to be able to talk to anyone he met, and could say a few words about relativity and quantum theory.

That’s because they are all physics giants, and for those who deal with Li Qiwei, winning the Nobel Prize is just basic knowledge.

When Li Qiwei returns to Asia, it will be like the Trisolarans descending on Earth, a pure dimensionality reduction attack.

Moreover, the topic he gave to Xia Yuanzhao was an experiment that caused great controversy in later generations.

That is the double-slit interference experiment that is said to be illogical.

The original Young's double-slit interference experiment is a very easy to understand experiment.

But when later generations were able to master the technology to emit single photons or electrons and take into account the wave-particle duality, things started to get weird.

Physicists have discovered that the observer actually has an impact on the measurement results.

When you observe it, a single photon exhibits particle properties; when you don't observe it, a single photon exhibits wave properties.

Especially the delayed photon experiment based on it, which even overturned the cause and effect relationship.

This is also the experiment that marketing accounts and clickbait headlines love to brag about in later generations, with all kinds of shocking and counterintuitive content, such as physics no longer exists and so on.

In fact, it is all caused by half-knowledge, and the experiment itself is not that rare.

The so-called double-slit interference experiment is not magical at all, there is nothing weird about it, and it will not subvert cause and effect.

It’s just that ordinary people have a misunderstanding of the word "observation", and are constrained by their inherent thinking about the phenomena in the quantum world.

However, in order to understand this issue clearly, many prerequisites are needed.

Li Qiwei is not prepared to explain to everyone here for the time being.

For such a big shot, I must wait until he returns to Europe before I can pretend.

So, when Xia Yuanzhen finished talking about his graduation thesis, Ishihara Jun was stunned.

The situation is different from what the script predicted.

Isn't it said that Li Qiwei's three disciples are very ordinary? They haven't even published a paper.

Why can’t I understand what people are saying now?

Jun Ishihara asked for help from Hantaro Nagaoka in a wronged manner. The current atmosphere was a bit too awkward for him.

However, Nagaoka Hantaro was no less shocked than his students at this moment.

Because he found that the questions that this young man named Xia Yuanzhao thought about were simple but very profound.

The physical essence contained in it made him a little frightened.

He turned his gaze to Li Qiwei, only to see a faint smile on the other's face.

Nagaoka Hantaro was restless: Mr. Li, is this your strength?
Just some casual guidance can enable students to study such profound physics problems.

I am a professor at the Tokyo Imperial University, and I can't explain this problem clearly.

This thought experiment is really fascinating.

At this moment, Nagaoka Hantaro had already realized that he had underestimated Li Qiwei.

Not only is that man awesome himself, but the students he teaches are also awesome.

It’s not that they haven’t published papers, but they just don’t bother to publish simple papers.

The new method of Poisson spot may seem as naive to others as calculating the slider speed.

Nagaoka Hantaro put away all his hopes of luck.

In his eyes, Li Qiwei has become the number one rival in the entire scientific community of Sakura Country.

With such a powerful opponent, the future of science in Sakura Country is destined to be difficult and tortuous.

"Ishihara-kun, please step down."

"Xia Jun's research has exceeded your scope of knowledge."

"Even for me, I can't find a reasonable solution to verify this experiment."

Then, Nagaoka Hantaro said to Li Qiwei: "Mr. Li, I really envy you for having such an excellent student."

"I really want to learn how you train your students."

Li Qiwei laughed and said, "I don't have any methods. They are just self-aware."

"When they were studying in Cambridge, England, the three of them studied until midnight every night, and they would not listen to my advice."

"Good students are never taught."

Nagaoka Hantaro secretly curled his lips and said, I don’t believe you at all.

If you don't personally guide them, it's impossible for them to be that talented given their age.

Nagaoka Hantaro himself has also taught students.

Naturally, one can tell at a glance that Xia Yuanzhen is definitely not a genius.

But they have such an awesome teacher that even a little bit of leakage between their nails would be enough to make them famous all over the world.

Xia Yuansong was confused throughout the whole process. What was going on? Didn’t he ask me to discuss academic matters with the other party? Why was he silent?

Isn’t the wave-particle duality of light a very basic thing? It has been published for three years, there must be someone who doesn’t know it.

The simple-minded Xia Yuanzhen didn't even realize that he was pretending to be so pretentious.

Invisible pretense is the most deadly.
