Grandma's wanton life

Chapter 527

Ye Feng passed the test with a dazed face, although everyone said that no one came out right, but this feeling is quite weird!
Not right!

However, no one paid attention to Ye Feng.

Over there, Principal Wu said again, "Professor Ye has passed the first hurdle, but the second hurdle is not so simple. Come on, from the Department of Mathematics." Principal Wu waved his hand.

Ma Luan, the dean of the Department of Mathematics, stepped forward and said with a smile, "Professor Ye, this second test is a matter for our Department of Mathematics. Let me give you a vaccination first. Our question is not as fancy as that of the Department of Literature. Yes. This question is really difficult, if you can't solve it before the auspicious time, send some red envelopes to our department and we can let you pass it."

Dean Ma's words made it clear. Originally, Zhao Huangming and the others also meant the same thing in the first pass. No one really wanted to make things difficult for Ye Feng, but just wanted to have fun and ask for a few red envelopes.But who would have thought that Ye Feng would come up with an upper couplet in the first level, and Zhao Huangming and the others let Ye Feng pass the level in a daze.Of course, no one has discovered the mystery of this Shanglian until now.

With this lesson learned, Dean Ma said this as soon as he came up.

The guests all smiled.

Everyone understands that this is just a fun show.

However, Ye Feng's temperament is still a master who refuses to admit defeat. This guy is usually a good-looking guy, and he wants to be soft when he gets married today?
That's almost impossible!
The last level let you fool me in a daze, do you still want to fool me this time?

nonexistent!

Ye Feng rolled up his sleeves, "Come on, let the horse come here, I have never been afraid of mathematics!"

"Got it."

Dean Ma smiled maliciously, "That's what you said, so I'll ask the question?"

Ye Feng smiled confidently, "Come on, I'll continue."

Dean Ma smiled and said: "For the second level, our mathematics department has only one problem." Ma Luan stretched out his hand and gestured, and said, "Professor Ye, what is the sum of all natural numbers?"

After Dean Ma finished speaking, all the guests present were stunned.

The sum of all natural numbers?
What the hell kind of question is this?
Even if you don't do mathematics, even Mr. Song Qingxuan, who is good at calligraphy, knows that there are infinitely many natural numbers. How can this thing sum?

This is impossible to have and ah!
Many people are confused when they hear this question.

Only a few old mathematics professors from Tsinghua University and Peking University and a few universities were slightly taken aback.

Dean Ma is good at it, and explained with a smile: "This question is actually easy to understand. The natural numbers are 0, 1, 2, 3, 4... How much do you add them together? Professor Ye?"

Director Jin from the sports department nearby said with a wry smile: "Dean Ma, you really don't want Professor Ye to pass the test."

Dean Hu of Peking University's Chinese Department shook his head and said, "It's obvious that Professor Ye is asking for a red envelope. This thing can't be counted!"

Zhao Huangming gave thumbs up to the people in the mathematics department, "You still know how to play, I'm convinced!"

Seeing what everyone said, Dean Ma said obediently when he got a bargain: "Professor Ye is the one who has solved the world's top ten mathematical conjectures. This problem may be clueless to others, but it is not difficult for Professor Ye." Right? If you really want to make it difficult for Professor Ye, let's just make a guess, isn't it more difficult than this?"

"Ha, there seems to be some truth in what you say."

"I'm convinced of studying mathematics."

"Not only did he not understand this question, he didn't make any sense!"

"That's right, even if you figured out this thing, what can you do?"

"Yeah, the sum of all natural numbers? What's the use of that?"

"Forget it, Professor Ye, you should give the red envelope directly."

"This thing can't be calculated!"

Many people have started to persuade Ye Feng, this question is obviously because they don't want Ye Feng to pass the test!

The sum of all natural numbers?
This is no joke!

Even the outside media smiled wryly when they saw it.

They have seen a lot of people who get married and make things difficult for the groom, some who drink alcohol, just like the first level, some who let them eat apples, and those who hide the bride's shoes, all kinds of things.However, this is the first time they have seen someone like Professor Ye who is being made difficult by such a fancy and professional high-ranking question!

On the other side of the rostrum, two hosts were mobilizing the atmosphere of the scene.

The hostess held the microphone and said with a smile: "Professor Ye passed the first test smoothly, but the situation of the second test is not very optimistic now. Can Professor Ye pass it smoothly?"

Male host: "I'm confused, I guess Professor Ye is going to pay a red envelope."

"Hey, Professor Wang, you are an expert in this field, help Professor Ye think about it."

"Yes, Lao Li, quickly help Professor Ye do the math."

"This question is too boring, what's the deal with this thing?"

"To be honest, someone has calculated this problem a long time ago, but the final values ​​are too big."

"This number must be big, it's too big!"

"Don't talk about the addition of all natures. It is the addition of infinite 1s and infinite 100s. They are all the same. The result is infinity!"

Many people shouted, calling the mathematics professors on site to help, but there are so many experts and professors engaged in mathematics at the scene, including Peking University, Tsinghua University, and even old professors from the Chinese Academy of Sciences, without exception. They all shook their heads at the question.

Faced with such a perverted, boring and meaningless question, everyone is really powerless. Who can calculate the sum of infinite numbers?
This is obviously an infinite series!

And it's a divergent infinite series!
As we all know, what diverges is meaningless!
Let alone the sum of all natural numbers, let’s talk about what the last natural number is. Everyone doesn’t know, so how do you calculate it?
It's impossible to figure it out!
Looking at them, Dean Ma and the people from the Department of Mathematics of Haida University laughed.

They didn't come up with this problem. This problem was studied by some people in the Western mathematics circle around the 78s. However, those mathematicians in this world found that this thing is really meaningless, and finally researched it. What can I do?
It's useless!

Therefore, in the end, no mathematician will calculate this thing.

This question has been neglected in the mathematics world for hundreds of years, but Ma Luan brought it up again today to make things difficult for Ye Feng.

However, at this moment, Ye Feng, who had been raising his eyebrows in thought, suddenly smiled, looked at Ma Luan and the others, and said with a smile: "Is that the question?"

Ma Lun was taken aback, "Huh?"

A mathematics professor at Peking University over there was also taken aback, "What do you mean?"

Ye Feng smiled lightly, "Are you sure it's this?"

Dean Ma: "Sure, this is it, you do the math!"

The reason why this question is not included in the top ten conjectures is because mathematicians feel that this thing is meaningless, but in fact the difficulty of this question is no less than those ten conjectures. The average mathematician sees this question They would all be discouraged, so seeing Ye Feng's relaxed expression, Dean Ma's heart beat a little. Professor Ye couldn't really figure it out, could he?After all, he is the man who solved Goldbach's conjecture!
Dean Ma emphasized: "Professor Ye, you can't just say a number to fool us."

Ye Feng sighed lightly.

Dean Ma said: "You have to write down the steps."

Ye Feng didn't care about it again.

Dean Ma swallowed, "Then you do the math."
