British writer

The atmosphere in the cafe is a bit eerie.

Roland touched his nose awkwardly,

"Indeed, I was sent by the French Academy to pick up the two for the exchange, but I am a graduate of the Ecole Normale Supérieure, so I can only advise the school."

Bernard Shaw was puzzled, "Then why did the French Academy choose you?"

Roland replied: "Do you still remember Mr. Hamsun criticizing Professor Lu in the newspaper?"

Lu Shi was stunned for a moment, and memories emerged.

He once mourned Oscar Wilde in "There Were None", which caused Hamsun to vent,

Hamsun's original words are: ""And There Were None" is well written, but its roots are as crooked as Mr. Wilde's. I don't know if the Chinese novelist took root in the wrong place and grew a plant. poisonous weed."

Later, many literary critics and writers also joined in and became the "Taolu" faction.

And Roland is a "Pro-Lu" faction, defending Lu Shi.

The two of them formed a good relationship.

Lu Shi nodded,

"understood."

He can understand the good intentions of the French Academy.

Roland chuckled and said, "Hahaha, I can only count the non-staff personnel of Lanxi College."

After speaking, the subject changed,

"About upgrading your book to a teaching material..."

Lu Shi did not express his opinion.

This silence was naturally interpreted by De Roland,

He showed a joyful expression,

"Thanks!"

Once the words "Thank you!" were uttered, countless students in future generations would have to curse at Lu Shi in their hearts if they were to suffer for it.

Bernard Shaw said, "It's almost time to rest, let's set off quickly."

Roland nodded,

"Mr. Poincaré should have been waiting for you. It is said that he also invited Mr. Verne. We will definitely have a drink tonight."

After speaking, they finished their coffee and left the cafe.

Feiffer left on his own,

The other three went straight to the French Academy.

The French Academy consists of five colleges:

The French Academy, founded in 1635;

The French Academy of Inscriptions and American Letters, founded in 1663, later became the French Academy of Letters;

French Academy of Sciences, founded in 1666;

French Academy of Fine Arts, founded in 1816;

The French Academy of Humanities, founded in 1795.

The core of which is the French Academy, composed of forty academicians,

These academicians have an informal title, "les immortals", which directly translates to immortals, which also implies the lifelong tenure of academicians.

Roland took them to the place,

After the concierge asked, a staff member came in to report immediately,

Soon, a fat French man with glasses came out, shook hands with Lu Shi enthusiastically, and said at the same time: "Professor Lu, Mr. Xiao, you are here! I have been waiting for a long time!"

He introduced himself: "I am Henri Poincaré, an essayist."

Bernard Shaw scratched his head when he heard that,

He had never heard of any essayist named Poincaré.

On the other side, Lu Shi smiled and said, "Mr. Poincaré really likes to joke. You are clearly a mathematician, a physicist, and a philosopher of mathematics."

For later generations of science and engineering students, Poincaré is the one who is really hated,

Lu Shi was too small to see the big witch.

Poincaré was amazed,

"I do write prose too. It's just that I didn't expect Professor Lu to be proficient in natural science."

Bernard Shaw chuckled and said, "Mr. Poincaré, Lu is an interdisciplinary scholar. His monograph "Guns, Germs and Steel" covers many subjects, and has been requested by Mr. Roland as a textbook for the Ecole Normale Supérieure."

Poincaré: "Huh?"

He looked at Roland with sharp eyes,

stare--

Roland staggered his eyes in embarrassment, and muttered, "The wind is very noisy today~"

Poincaré said: "Then my alma mater, the University of Paris, will also use it as a textbook."

Although I don't know what "Guns, Germs and Steel" specifically wrote, Poincaré must not be left behind.

Lu Shi was speechless for a while.

A few people chatted a few more words,

Poincaré said: "Let's go first, arrange accommodation for Professor Lu and Mr. Xiao, and call someone who can really chat with Professor Lu. It's better for me, an essayist who is half-dangling, to consciously retreat behind the scenes. "

He led the three of them to the academy.

The French Academy is more of a research institution, with extremely weak educational attributes and no students at all.

It didn't take long for them to arrive at the dormitory.

Compared to Poincaré, Roland is a young man,

So I left it to him to call Verne.

Poincaré was in charge of the reception, and while rummaging through boxes and cabinets, he said: "I heard that both the British and the Chinese like to drink tea. I have brought out the best tea, and you two must try it."

Soon, there was a small round box in his hand,

There was a label on it, and George Bernard Shaw squinted his eyes for a long time before muttering, "A word you don't know...is it French?"

Lu Shi looked at it and said, "It doesn't look like it, it's a language I don't know."

Although the two chatted in a low volume, Poincaré still overheard them.

He was shocked and said: "This is obviously a Chinese character!"

Lu Shi:? ? ?

He leaned over to look carefully, and after a long time, he complained helplessly: "This is a Chinese character written by you French, it looks like a dog crawling."

Poincaré couldn't help feeling embarrassed,

"Ah this..."

Lu Shi explained: "It's indeed Chinese characters, it says 'Longjing Mountain'."

Hearing his words, Bernard Shaw immediately regained his spirits,

"I know 'Dragon'! Dragon!"

This old man is quite cute.

Lu Shi said: "Mr. Supervisor, Chinese dragons are still different from Western dragons~"

It is precisely because of this that later translators tended to translate the Chinese dragon into "Loong", rather than "Dragon", a large lizard with wings.

Of course, Bernard Shaw didn't understand these things either, so he asked curiously, "What is this 'Longjing Mountain' you're talking about?"

Lu Shi replied, "The origin of the tea."

Poincaré opened the box.

Bernard Shaw probed over and said in surprise, "Lu, this tea is so strange."

Lu Shi asked, "Why is it so strange?"

George Bernard Shaw pointed to the tea,

"The color is actually slightly yellow... I heard that you Chinese don't like to add spices to your tea, so you have to fry the tea carefully, but shouldn't the tea leaves be green?"

Lu Shi didn't know much about tea either, so he could only answer: "It's probably a question of the variety."

Embarrassed, Poincaré took off his glasses and wiped them vigorously.

"Could it be that they made fake tea leaves?"

Lu Shi said, "I don't know, but Pao Pao will know it after looking at it."

Poincaré and Bernard Shaw consciously moved away from the table, then looked at Lu Shi with searching eyes,

"Hot water is ready, please."

Lu Shi: "..."

I had to rush the ducks to the shelves.

He washed his hands, warmed the cup with hot water, and then used a teaspoon to put the tea into the cup.

Then lift the kettle high, pour in an appropriate amount of water to cover all the tea leaves, and then draw a circle with a large circle and a small circle, and fill the cup with water to a quarter of the height.

As soon as the experts make a move,

Just know if there is.

Neither Poincaré nor Bernard Shaw had ever seen tea brewed like this.

Lu Shi held up the glass with both hands, and gently shook the glass in one direction,

The Dragon Well inside first floats and then sinks, like a dancing beauty.

The warm tea leaves exude a fragrance.

Lu Shi actually didn't know how to make tea in a high-quality manner, but after such an operation, it was enough to fool foreigners.

Bernard Shaw couldn't help feeling: "It's really art."

Poincaré said: "Professor Lu is really well versed in the ways of Chinese literati... Well...Professor Lu, I heard that you Chinese students are good at writing brush calligraphy. I wonder if you can give it to me...Ah, no, it should be for France. The academy left a copy of calligraphy."

Lu Shi suddenly had one head and two big ones,

For him, writing brush characters is a very difficult task,

It's easy to say, that's called "eclectic";

To put it bluntly, it is called "opening teeth and dancing claws".

He quickly changed the subject and said, "Let's drink tea first, drink tea first and then talk."

As an Englishman, George Bernard Shaw couldn't wait any longer, he put the teacup to his lips and took a sip,

The tea fragrance slowly ferments in the mouth,

"Gudong~"

He swallowed the tea.

After a while, he commented: "It turns out that the tea without seasoning is so delicious."

Lu Shi also took a sip,

It must be admitted that the quality of the tea produced by Poincaré is indeed high.

In modern times, this kind of tea may only flow out of the country if it is a diplomatic gift or a small amount of designated foreign trade.

Lu Shi asked Poincaré, "How did this tea come from?"

Poincaré replied: "It was bought at a high price from an officer."

As for how the officer got it?

This is a heavy question.

Lu Shi sighed slightly.

Poincaré was also surprised that what he said was a bit irritating, so he picked up his teacup and drank tea in a disguised manner.

Bernard Shaw blinked his eyes and asked, "Mr. Poincaré, Lu just said that you are a mathematician and a physicist, both of which are easy to understand. But what about the philosopher of mathematics?"

This question is to ease the embarrassment of having nothing to say.

Poincaré replied: "Philosophy of mathematics is a category of philosophy of science, and philosophy of science is a branch of philosophy that has only recently emerged. It focuses on the foundation, methods and meaning of science, and mainly studies the nature of science, the structure of scientific theories, scientific explanations, Scientifically tested..."

Five hundred words are omitted here.

Bernard Shaw did not expect that his well-intentioned act of finding a topic would lead to such a big mess.

He was stunned and dizzy when he heard it.

But Poincaré is an honest person,

After finishing speaking, he asked, "Does Mr. Xiao understand?"

Bernard Shaw was speechless, and spread his hands, expressing that he understood a hammer.

Poincaré went on to explain: "In fact, it is easy to understand, the problems of philosophy of science, for example, what qualifies as science, the reliability of scientific theories, the ultimate goal of science..."

Another thousand words omitted.

Bernard Shaw was even more dizzy,

"What... what? Say it again..."

Lu Shi listened to it and wanted to laugh,

He interrupted Poincaré, and said to George Bernard Shaw: "Give me an example. For example... Let me think about it... Mr. Chancellor, in your mind, is mathematics an invention of human beings or a discovery of human beings? It's a question of philosophy of mathematics."

George Bernard Shaw suddenly realized,

"understood."

Poincaré immediately felt defeated.

At the same time, he looked at Lu Shi curiously,

At this moment, he had the real feeling that Lu Shi was indeed an interdisciplinary scholar.

A question can make people who don't know much about the philosophy of mathematics have the most intuitive feelings, and not everyone can do it.

Poincaré asked, "What does Professor Lu think mathematics is?"

Lu Shi caught blind,

This question is completely in the blind spot of his knowledge.

He said: "It should be discovered."

Poincaré had a playful expression and asked, "Why did Professor Lu say that?"

Lu Shi fell into deep thought,

To be honest, he himself didn't know why.

Poincaré came to a conclusion, and continued: "It should be because Professor Lu is a historian that he came to that conclusion? In history, Plato firmly stated that 'mathematics is a discovery'."

Plato believed that once people understand a certain mathematical concept, they will face some indisputable facts,

This is a kind of materialism.

Lu Shi shook his head,

"No, I didn't think that far."

Poincaré pondered slightly, and said: "Not that far away? If you think about it a little closer, it's Euclid. Euclid thought that if one day someone claimed that he had discovered the largest prime number, it would be easy to prove his It's wrong."

Lu Shi and Bernard Shaw looked at each other,

After a while, Lu Shi asked: "What is the relationship between this mathematical deduction and 'mathematics is a discovery'?"

Poincaré: ? ? ?

"Do you need to explain such a simple thing?"

Fifteen hundred words are omitted here.

Bernard Shaw looked like a primary school student listening to a class, sitting upright, tugging at the hem of Lu Shi's clothes, and whispered, "Lu, stop him quickly!"

Lu Shi also raised his hand like a primary school student answering a question,

"etc!"

When Poincaré was interrupted, he was not dissatisfied, but showed a joyful expression,

This kind of joy is like the teacher who is in class seeing his disciples have the courage to ask questions.

He said, "Professor Lu, please speak."

Lu Shi said: "I say mathematics is a discovery because it gives me a real feeling and never deceives me."

Poincaré was puzzled,

"Won't cheat?"

Lu Shi nodded and said:

"

your eyes will deceive you;

your feelings will deceive you;

your experience will deceive you;

But math doesn't,

No, just no!

"

This is actually a Chinese pun,

But it's also perfectly spoken in English (No, it's just not!) or French.

The room was quiet,

After a few seconds,

"Pfft! Hahahahahahaha!"

Bernard Shaw laughed wildly.

Poincaré was stunned for half a minute before he realized it and couldn't help laughing.

He stretched out his hand to pat Lu Shi's shoulder, and said in a low voice, "Professor Lu, you said 'no, you just can't!', are you mocking me for forcibly instilling you with relevant knowledge of mathematics and philosophy?"

Lu Shi repeatedly shook his head,

"No no!"

Poincaré laughed even more happily,

He said: "It doesn't matter. It's a great fortune to know such a wonderful person as you. You can write a little poem casually for irony and advice~"

Bernard Shaw also said, "Yes, the poem just now is really good, does it have a name?"

Lu Shi said "ah?" and said in his heart:

That's not a poem at all!

But George Bernard Shaw got it wrong and said, "Looking at your expression, it seems that you haven't thought of a name yet. If that's the case, let me ask you to name this poem, how about calling it "Deception"?"

Lu Shi has a headache,

"Don't, don't you! I just told a joke."

George Bernard Shaw said: "I understand, "His Majesty the Supreme Emperor Arrives Today in His Faithful Paris" is such a joke~ But it does not prevent this joke from being a poem with profound meaning."

After speaking, he turned to Poincaré,

"Monsieur Poincaré, do you have a pen and paper here?"

Poincaré nodded first,

"some!"

But soon shook his head again,

He stared at Lu Shi with a strange gaze, like a hunter looking at his prey.

Lu Shi shivered and said, "Mr. Poincaré?"

Poincaré chuckled,

"Professor Lu, didn't you mention the brush calligraphy? Why don't you keep a copy of calligraphy?"
