"Everyone here must have gone to elementary school.
"This unknown number, written on paper, is a big cross.
It is pronounced as Yes, it’s wrong in terms of causation.”
Professor Zhao held one hand on the table, leaned on the podium and looked at everyone and said, "Actually, this x has appeared since the Tang Dynasty.
In ancient my country, it was not called x or a cross, but just a In other words, "Hun" first appeared in my country, and then the "X" appeared in Old English.
The person who invented the symbol "Hun" was the swordsman Li Bai.
He was the first mathematician in my country to propose solving equations, and he was also the inventor of the character "Hun". ” What the hell The man named Xunze Wooden Bench Pocket watched Professor Zhao introduce the various contributions of mathematician Li Bai to human mathematics, and his heart was filled with disbelief.
Why is it that in other people's homes, the protagonist is himself a copycat, but in my case, it is my student who is a copycat?
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 interests and hobbies to building a fencing gym after returning home, his talent was still there after all, so he still often wrote some poems.
But except for killing one person in ten steps, leaving no trace for thousands of miles.
Except for "Xia Ke Xing", the other poems are all ones that Xunze has never heard of and should be newly written.
Although the quality of these poems is good, on the one hand, Li Bai's identity as a swordsman conceals the fact that he is a poet; on the other hand, these newly written poems are not only small in number, but also mostly related to swordsmanship in content, so they have not received much attention in later literature.
As a result, few people nowadays have heard of it, and it has not been dealt with by literati.
Contrary to what everyone thinks, the poems we read now were written by the original author.
Many poems that have been circulated to this day were actually modified by later literati to adapt to 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 window, I suspected it was frost on the ground.
Looking up at the mountains and the moon, looking down at my hometown.
The reason There are discrepancies between the two versions because the literati later changed the content when rewriting it.
Among them, looking up at the mountain and the moon was changed to looking up at the bright moon.
This was changed in the Tang Dynasty's Wanli edition of Wanshou Quatrains. , and during the Kangxi period of the Qing Dynasty, the first line of Tang poetry published by the public was changed to "Moonlight in front of the bed".
Later, during the Qianlong period, people combined these two versions into what we now know as Jingyesi.
Of course, this change has advantages and disadvantages.
The advantage is that it is easier to understand, but the disadvantage is that it misinterprets the original meaning, because the bed Li Bai mentioned is not the current bed, but the well railing.
Hence the popular saying at night that there is bright moonlight in front of the bed and two pairs of shoes on the floor.
This sentence is actually not a poem by Xiao Huang, but a poem of horror.
Because two pairs of shoes suddenly appeared beside the well railing, it is easy for people to think deeply about it.
After about half an hour, Professor Zhao finished talking about Li Bai’s identity as a mathematician and poet, and then the program came to the audience’s questions.
"Hello, Professor Zhao."
A young man wearing gold-rimmed glasses stood up and said to Professor Zhao, "You just said that the x we are using now was actually invented by Li Bai.
I disagree with this.
Because the national history community There has been debate about this.
Most Western scholars believe that solving equations was actually invented by Westerners.
The fact that Li Bai invented solving equations and x in the Tang Dynasty only exists in some unofficial records and is not recorded in the official history of my country.
The relevant arithmetic books do not clearly state that Li Bai was the one who invented mixed numbers, not to mention that there is still a big gap in our country's setting of mixed numbers and solution equations."
After hearing the question from the man with gold-rimmed glasses, Professor Zhao was silent for a moment, and then said, "Our country's hypothesis-confusion numbers are indeed somewhat different from modern equation-solving methods, but they already have a rough basis for understanding equations.
And Li Bai invented the hypothesis Although the matter of confusing numbers and The ancient historical records of our country are almost legendary, so I think this matter is still very authentic.”
"But after all, it is only authentic, not the real thing."
The man with gold-rimmed glasses continued to question, "Without relevant physical objects and archaeological records to support it, I think it is very wrong for you to rashly say this conclusion with absolute certainty today.
After all, the conclusion I mentioned is agreed by European and American scholars.
"Why do European and American scholars speak the truth, and what our Chinese scholars speak is just a family's opinion?"
Professor Zhao was a little angry.

"Can I ask whether European and American scholars have any material to support their theories?
They don't have any, so why do they ask us to have it?"
Because the program was recorded and broadcast, Xunze did not see the subsequent argument between Professor Zhao and the man with gold-rimmed glasses, and it should have been edited out.
After all, the part just now was left to stir up the topic, and if it is broadcast further, it will seem to be able to set the rhythm.
However, calling him Xunze did not dispel the suspicion of the man with gold-rimmed glasses.
The problem of double standards in the field of history has always existed.
Xunze was not a professional in the field before, so he didn't care about it, but he didn't expect that this time it would be related to him.
Why didn't Li Bai invent x and create an equation?
I taught him personally, how can this matter be false?
Although before the timeline changed, solving the equation did not have anything to do with Li Bai.
But now the timeline has changed.
Li Bai was indeed the first person on earth to master solving equations and setting up unknowns.
Why is something wrong?
Why is there no physical objects or archaeological records to support it?
No, I’m so angry.
When Li Bai comes back tomorrow, let this guy Li Bai completely understand the equations for me.
Not only must he teach it to all the disciples he will accept in the sword hall in the future, but he must also compile it into a book and bury it in a coffin.
If anyone dares to question at that time, let Li Bai tell him the location of his coffin, and he will take his people to dig out the coffin and respond to these people with real objects:
