The Rise of the Cold Gate in the Eastern Jin Dynasty

Chapter 159 This gathering in the second year of Shengping!

In order to make it easier for everyone to accept the original theory of calculus, Xiao Qinzhi also gave an example from "Zhuangzi · Tianxia", which records "a hammer of one foot, take half of it every day, and it will last forever". Assuming that the hammer is one foot long, take half today and tomorrow Take half of the half, and so on, take the remaining half every day, and you will find that you can't take it all in your life.

However, it is impossible to achieve in practice, because the division of objects has a limit. A piece of paper can be folded infinitely, and the thickness can be infinitely long, but after actually folding it in half several times, it cannot be folded.

So, this is also a calculus problem infinitely tending to one.

Under Xiao Qin's vivid explanation with both pictures and texts, witty people have already understood the concept of "infinite tends to a certain value", so they also understand the philosophical meaning of "the sight of flying birds is not moving", but it is incompatible with reality. There is a paradoxical proposition.

In fact, decades ago, a mathematician named Liu Hui put forward a great idea, that is, the "garden cutting technique". Then it becomes one with the circle, and nothing is lost.

Precisely, this is also the idea of ​​calculus.

Following this idea, he kept cutting, and finally cut out pi 3.1415 and 3.1416. After about 70 years, a great mathematician, Zu Chongzhi, will come to this world. He will use this idea to the extreme and come up with The last seven digits of pi were added, which is about 1000 years earlier than that of Europe in the same period.

By mistake, Xiao Qinzhi used "the scenery of flying birds is not moving", leading to the original theory of calculus in advance. I believe it will be of great help to Zu Chongzhi decades later, and mathematicians hundreds of years later. They have some influence.

The result of "clear talk" is self-evident, but Xiao Qinzhi has been making things difficult for him until now, so he can't always be passively making things difficult for him, so he decisively put forward a larger philosophical concept on the basis of his predecessors, that is, "Don't hesitate to use today's me to make it difficult for me in the past."

In layman's terms, it means "the me of yesterday and the me of today are not the same me", this is Xiao Qinzhi's quote from Mr. Liang Qichao's debate in the Qing Dynasty. During the Wei and Jin Dynasties, Chinese philosophy passed through the pre-Qin schools of thought , once again ushered in its heyday, so this infinitely huge debate topic "I am yesterday and I am today" immediately aroused heated discussions.

Xiao Qinzhi, who proposed this debate, naturally became the object of everyone's pursuit of knowledge, and Xiao Qinzhi, who was weak and bad, resolutely pretended to be a super big coercion, and introduced the space-time dimension head-on for the first time.

"If time is a river, I stood upstream yesterday, and today I float downstream with the current. Although I am still me, I am not that me anymore." Xiao Qinzhi said calmly, and provided Think from an angle.

Then the group of "metaphysicians" fell into contemplation, and then discussed in a low voice.

Therefore, what should have been a life-and-death debate turned into a philosophical discussion with profound significance, which made people laugh and cry.

The purely academic discussion was very boring. Not long after, the emperor and the queen mother left, and some people who could not grasp the threshold of philosophy also left, leaving a group of "metaphysics" bigwigs discussing in full swing.

But just because they left and spread the details of this rally, Xiao Qinzhi gained a lot of limelight. Even a few years later, when people looked at this history and saw this rally, It is possible to remember the name "Xiao Qinzhi".

From the first rising of the sun to the setting sun on the western mountain, the discussions in Qingliang Hall were endless and enthusiastic. In order to commemorate this far-reaching gathering, someone proposed to follow the example of the ninth year of Yonghe and write an article for each person. All the articles are bound into a volume for records and for future generations to observe.

This proposal was unanimously approved by everyone, so who is Wang Xizhi in this preface?
Xiao Qinzhi was invited to write an article out of the ordinary. This is a good opportunity to show his face. Usually it is reserved for big bosses. He really envies many young people. Thinking that his article is listed with the big bosses, he is very excited. .

But the article must be well written, if the writing is poor, then it is not famous, but embarrassing, Xiao Qinzhi wrote carefully, but he could not write for a long time, Xie Xuan enthusiastically suggested: "You are stupid, write poetry. "

Poetry is naturally possible, but I always feel that there is a lot of difference. In Chinese literature, poems, songs, and poems are always the protagonists, and they are by no means comparable to poems. They should rank first.

Suddenly, I saw Xiao Qinzhi put down his pen, walked out of the Qingliang Hall, and stood on the Jiuhua Terrace. The warm light of the setting sun shone obliquely on the extremely gorgeous Hualin Garden, creating a peaceful atmosphere. It is magnificent, and Jiankang City is the number one city in the world, but they almost forgot that this is Jiankang, not Luoyang, which is overgrown with withered grass and ruined.

"The warm wind makes tourists drunk, and Jiankang is regarded as Luozhou."

How similar this situation is to the prosperity of Lin'an City in the Song Dynasty, it can't help but make people feel embarrassed, so Xiao Qin came to the inspiration all of a sudden, and said sorry to Du Mu in his heart, and I will lend you a poem.

Xiao Qinzhi wrote "A Fang Gong Fu" when he picked up his pen: "Six kings are finished, the four seas are one; Shushan Wu, A Fang comes out. Covering more than [-] miles, isolating the sky and the sun. Lishan is built in the north and turned west, going straight to Xianyang. Erchuan Rong Rong, flowing into the palace wall. Five steps to the first floor, ten steps to a pavilion; corridors and waists back, eaves and teeth pecking high;

This opening chapter, the language is neat but not piled up, rich but not flashy, majestic and unrestrained in style, if it is written down like this, it seems that a famous fu will be published, and it will attract the attention of many people at once, standing in front of Xiao Qin. Beside him, he held his breath and concentrated, not daring to disturb him.

The shape of Yan Kai's characters is very suitable for such a magnificent poem as "A Fang Gong Fu", and the two complement each other, so Xiao Qinzhi wrote very slowly, trying to combine the famous essay with calligraphy, making it perfect, so that it is short It's more than 500 words, and I didn't finish writing until dark.

Whether an article is well written does not depend on whether the rhetoric is gorgeous, but whether it has the inspiring meaning to break through the time limit. Obviously, "A Fang Gong Fu" has done it, and there is a reason why it can be passed down through the ages.

The Epang Palace was so magnificent that it led to the death of Qin II, and then summed up the historical lessons of the demise of the Six Kingdoms and Qin, and finally reminded future generations not to repeat the same mistakes of the death of Qin. It will also make future generations feel sorry for future generations." Ending with some questions.

With the publication of this "Ode to Efang Palace", the Jiuhuatai Gathering in the second year of Shengping has also been written into history. In a sense, it has surpassed the Lanting Gathering in the ninth year of Yonghe.

And this gathering made Xiao Qinzhi, a great writer, was born, and he was only in his twenties. This is the most eye-catching and enviable thing.

In the second year of Shengping, the gathering on June [-] is destined to be extraordinary!
[I will continue to study Ming history, don't rush me! 】
