"Professor Huang, your topic is too simple, you can know the weight by weighing it. Pen %Fun %Pavilion www.biquge.info"

An audience member stood up and replied to Huang Yifan.

"Hehe, this classmate, the ancient name is not as developed as the modern one. It is recorded during the Three Kingdoms period that the maximum weight was only 250 catties. Adult elephants are generally 4-7 tons, and even more giant elephants can reach more than a dozen tons in size. Although Sun Quan's elephant dedicated to Cao Cao did not say how big it was, it must not be small. Not to mention more than a dozen tons, presumably there are several tons. And elephants weighing several tons cannot be measured by scales. ”

This one denied it, and everyone in the audience woke up.

Yes, that was in ancient times, and it was also in the Three Kingdoms period, when the productive forces were not very developed.

During the Three Kingdoms period, if you want to weigh dozens of tons of things at once, it is basically impossible.

Later, someone also stood up and replied, saying that they had killed the elephant and weighed it piece by piece.

Of course, although this stupid method is feasible, who would dare to kill the elephant sent by Sun Quan?

The discussion came and went, and after a while, everyone shook their heads: "Professor Huang, your question is too difficult." ”

"It's a bit hard. ”

Huang Yifan nodded: "At the beginning, I didn't think of any good way. However, I didn't expect that Cao Chong, who was only 5 years old a thousand years ago, thought of it. ”

Looking at the disbelieving look of everyone in the audience, Huang Yifan smiled and said: "I know that you may not want to believe it, then, I will announce the answer." ”

While speaking, Huang Yifan turned on the big computer screen, and at this time, an elephant was drawn on the screen, and several ancient people were also drawn standing in front of the elephant.

"This painting is the scene of the elephant at that time. The ministers had no choice, and then Cao Chong walked up to his father Cao Cao and said, Father, I have a way. Cao Cao asked, "Cao Chong, we adults have nothing to do, what can you do as a child?" Cao Chong then said, we can drive the elephant to the boat and make scratches where the water has not passed the traces of the boat. Then the elephants are driven off the boat and carried to the boat in kind......"

The ppt demonstrated the whole process of Cao Chong's elephant evaluation, and everyone in the audience was shocked again when they saw this scene.

Using buoyancy, Cao Chong perfectly solved the problem of elephant weight. So, to calculate the weight of an elephant, we just need to weigh these objects one by one. ”

Huang Yifan finally announced the answer: "This story is called Cao Chong's elephant." ”

Again, applause applauded.

"Wonderful. ”

"Awesome. ”

"Before, I thought that Professor Huang didn't talk about Kong Rong too much, but now that I think about it, this Cao Chong is more interesting. ”

"Yes, yes, Cao Chong, who is only 5 years old, is as wise as an adult, and this intelligence is even more powerful than his brother Cao Zhi. ”

"It's just, no. Professor Huang, I seem to remember that you said in the last class that Cao Cao liked Cao Zhi very much at that time, why did he like Cao Chong the most? If he likes Cao Chong the most, he should consider making Cao Chong the son, how can he have the idea of making Cao Chong the son?"

Because they are two brothers, Cao Zhi, who finished the previous class, still remembers it vividly in the audience. At this time, when Cao Chong was mentioned, some listeners stood up and asked Huang Yifan a question.

That's a good question. ”

Huang Yifan nodded and said, "This is also what I am about to say." ”

"Cao Chongtian is a genius, at the age of 5, he showed amazing intelligence, and he is not inferior to adults, and even better than adults in some aspects. Therefore, Cao Cao's favorite is Cao Chong, and he also has the idea of making Cao Chong the prince. It's just that there are unforeseen circumstances in the sky, and people have good and bad luck, and Cao Chong unfortunately contracted a serious illness when he was 13 years old......"

With a sigh, everyone in the audience secretly screamed that it was not good, and then, when they heard the word "untimely death", everyone was completely dumbfounded.

"I'm dying!"

"Damn, no. ”

"God is jealous of talents, what a god is jealous of talents. ”

Many people are a little incredulous.

"Sister. ”

"What a genius, I thought I was waiting for him to reach the pinnacle of life, but I didn't expect to die. ”

"Yes. Cao Zhi was the same last time, I thought Cao Zhi was a powerful character. Unexpectedly, in the end, he was abolished by Cao Cao. However, this can't be blamed on Cao Cao, it's Cao Zhi's Taiwenqing, who thinks it's great to be favored if he is talented, so he died. However, this Cao Chong didn't make a mistake. However, God actually accepted him. ”

Quite a few people whispered comments.

"History is sometimes so helpless, just like our lives. Cao Chong's death was a great blow to Cao Cao. After Cao Chong's death, Cao Pi came to comfort Cao Cao, Cao Cao looked at Cao Pi, and said sadly, this is my misfortune, but it is your great luck. After saying that, Cao Cao shed tears. and also hired Zhen's dead daughter for Cao Chong to be buried with him, posthumously presented him with the official seal ribbon of the captain, and ordered Cao Cong, the son of the Marquis of Wan, to be Cao Chong's descendant. ”

At this point, the second class of the Hundred Pulpits has ended.

……

"Kong Rong let the pear. ”

Cao Chong called the elephant. ”

Watching Huang Yifan's second episode of the TV landing on the Hundred Lectures, Zhou Binglin, a professor at the Department of History of Yan University, scolded: "It's messy, what are you talking about." ”

Whether there are stories in the history of "Kong Rong Makes Pears" and "Cao Chong Calls the Elephant", Zhou Binglin cannot verify it. He is an expert in the history department, so he naturally knows that you can't verify this kind of lace story at all. If you really want to verify it, there will be a lot of non-existent content in history, but we have always believed that there is a contradiction. For example, people have always believed that Qu Zi died by throwing himself into the river, but according to research, Qu Zi probably did not throw himself into the river. You insist on saying a reason in it, but there is no need.

So, you can't say that he changed history. Moreover, what Huang Yifan studies is not historical events, but historical figures. The event can be researched and verified by what time, place, and what happened, but as long as you tell the character clearly, it will be considered a success, and there is no such thing as changing or not changing. Besides, when anyone interprets a character, he will add his own evaluation, his own opinion, and it is normal for a historical figure to behave differently in the eyes of different people.

Kong Rong and Cao Chong are both very smart and virtuous representatives in history, if you interpret it only from the aspect of characters, Huang Yifan's lecture is undoubtedly extremely exciting. At least, even Zhou Binglin, who is not interested in Huang Yifan, admits that Huang Yifan's interpretation suddenly made him remember Kong Rong and Cao Chong.

In particular, Kong Rong asked Li and Cao Chong to call these two stories, whether true or false, these two extremely classic stories will inevitably affect countless people in later generations. Perhaps, it won't be long before schools will use these two stories to educate their students.

It's just that if Zhou Binglin wants to admit that Huang Yifan is powerful, he is a little unhappy.

Gotta figure figure it out.

Although Zhou Binglin didn't dare to question Huang Yifan openly, it was not impossible to secretly make a stumbling block for Huang Yifan.

After thinking about it carefully for a while, Zhou Binglin thought of a way.

"My misfortune, your great fortune. ”

Looking at what Huang Yifan said when he finally explained Cao Chong, Zhou Binglin nodded: "The next class should be about Cao Pi, and only Cao Pi inherited Cao Cao's position and became the founding emperor of Wei." ”

Zhou Binglin is a professor of history, and although the Three Kingdoms is not his most studied, he still has some understanding of the history of the Three Kingdoms. Just after analyzing, he guessed who Huang Yifan should talk about in the third class.

"In that case, before you start the third class, I will explain Cao Pi one step ahead of you. Hmph, I'd like to see. After I'm done talking about Cao Pi, see what else you have to say. (To be continued.) )
