My students can change history

Chapter 14 What I taught him personally can still be false

"Everyone here has been to elementary school." Professor Zhao looked around the studio and said, "Nowadays, in our elementary school mathematics textbooks, we will learn simple solution of equations. And the most important thing is to solve equations. One step is to set up unknowns.”

"This unknown, written on paper, is a big cross. It is pronounced as X in English and mixed in Chinese. Many people now think that the source of the cross in the equation is the English letter, but it is actually wrong. Yes, it is wrong in terms of causality.”

Professor Zhao supported the table with one hand, leaned on the podium and looked at the crowd and said, "Actually, this X has appeared since the Tang Dynasty. ! That is to say, it is the X that existed in our country first, and then the X that appeared in Old English. The person who invented the symbol of X is Li Bai, the sword fairy. By."

What the hell!

Ming Xunze stared dumbfounded at Professor Zhao's introduction of mathematician Li Bai's various contributions to human mathematics, and his heart was full of criticism!
Why is it that the protagonist of other people's family is to be a copy of the document, but now it is my student who is a copy of the document.

After Professor Zhao introduced Li Bai's identity as a mathematician, he began to introduce Li Bai's identity as a poet.

Although Li Bai shifted his hobbies to building a fencing gym after returning home, his talent is still there after all, so he still often writes some poems.But except for "Ten steps to kill a person, a thousand miles will not stay behind." 'Except for "Xia Ke Xing Xun", the other poems are called Xun Ze, who have never heard of them, and should be new works.

Although the quality of these poems is good, on the one hand, Li Bai's identity as a sword fairy concealed the fact that he was a poet; As a result, few people today have heard of it, nor have they been dealt with by literati.

Contrary to what everyone thinks, the poems we read now are written by the original author.Many poems have been handed down to the present, but they have been modified by later literati to adapt to the aesthetics of the times.

Take Li Bai's "Quiet Night Thoughts" as an example. The version we read is: There is bright moonlight in front of the bed, which is suspected to be frost on the ground.Raise your head to look at the bright moon, lower your head to think about your hometown.Li Bai's original version looked like this: Looking at the moonlight in front of the bed, I suspected it was frost on the ground.Looking up at the mountains and the moon, looking down at my hometown.

The reason why these two versions differ is because the literati will change the content when they rewrite later. Among them, raising your head to look at the mountain and the moon is changed to raising your head to look at the bright moon. In the Kangxi period of the Qing Dynasty, the folk-published "Tang Poetry Bie Cai" changed the first sentence to the bright moonlight in front of the bed.

Later, during the reign of Qianlong, people combined these two versions and became the Jingyesi we are familiar with now.

Of course, this change has both advantages and disadvantages. The advantage is that it is easier to understand, and the disadvantage is that it distorts the original meaning, because the bed Li Bai mentioned is not the current bed, but the well fence.

So the phrase circulating on the Internet, "Moonlight in front of the bed, two pairs of shoes on the ground." 'This sentence is actually not a little yellow poem, but a horror poem.Because there are suddenly two pairs of shoes beside the well fence, it is easy to think carefully and fear.

About half an hour later, Professor Zhao finished talking about Li Bai's identity as a mathematician and poet, and then the program came to the audience's questioning session.

"Hello, Professor Zhao." A young man wearing gold-rimmed glasses stood up and said to Professor Zhao, "You just said that the X we use now was actually invented by Li Bai. I don't agree with that. Because the national historiography There has been a debate about this in the world, and most Western scholars believe that the solution to the equation was actually invented by Westerners. The fact that Li Bai invented the solution to the equation and X in the Tang Dynasty only existed in some unofficial historical records, and it was not recorded in the official history of our country. The relevant ancient mathematics books did not clearly indicate that Li Bai was the one who invented the mixed solution number, let alone the gap between the mixed solution number and the equation solution in our country."

After hearing the question from the man with gold-rimmed glasses, Professor Zhao was silent for a moment, and then said, "Our country's method of setting and solving numbers is indeed different from the modern solution of equations, but it has roughly the rudiment of understanding equations. And Li Bai's invention Although there is no record of confusing numbers and X in the official history of our country, there are records in many unofficial histories compiled by the people. The authenticity of the unofficial history is not as good as that of the official history. But compared to the western ones that are almost legendary According to ancient historical records, the authenticity of our country's unofficial history is still very high. So I think this incident is still very authentic."

"But after all, it is only true, not a real thing." The man with golden glasses continued to question, "Without the support of relevant physical objects and archaeological records, I think it is very wrong for you to say this conclusion rashly and with absolute certainty today. After all, the conclusion I said is agreed by European and American scholars. The conclusion you said is just the opinion of one family.

"Why do European and American scholars speak the truth, while our Chinese scholars speak the same opinion?" Professor Zhao was a little angry. "Do European and American scholars have any material to support their theories? They don't have any, so why do they ask us to have one?"

Because the program was recorded and broadcast, Xun Ze didn't see the subsequent argument between Professor Zhao and the man with golden glasses, so it should have been cut.After all, the episode just now left a topic that can be discussed, and then broadcast it further down, it seems a bit deliberate and rhythmic.

But being called Xun Ze is not a problem for the man in the gold-rimmed glasses.

The problem of double standards in the field of history has always existed. Jiao Xunze was not a professional in the past, so he didn't care about it, but he didn't expect it to be related to him this time.

Why didn't Li Bai invent X and create an equation? !

I taught him personally, can this matter be false? !

Although the timeline has not changed, solving the equation has nothing to do with Li Bai.But now the timeline has changed.

Li Bai is indeed the first person on earth who mastered solving equations and setting unknowns!

Why is it wrong, why is there no physical objects and archaeological records to support it.

So angry.

When Li Bai comes back tomorrow, let this kid Li Bai completely understand the equation for me.Not only must it be taught to all the sword hall disciples he will accept in the future, but it must also be written into a book and buried in the coffin.At that time, who dares to question, let Li Bai tell himself the location of his coffin, and he will take someone to dig out the coffin and respond to these people with real objects!
