Baby daddy's unrestrained life

"Calculated?"

"It's impossible!"

"It is impossible to calculate the Casimir force!"

"This is the consensus of the physics circle!"

"Professor Ye, don't talk nonsense!"

"The Casimir effect is a force in a vacuum. Unless it is measured experimentally, it is impossible to get a numerical value!"

"It's unrealistic to calculate the Kashmir force. There are too many uncertainties involved in it!"

Ye Feng said that he could calculate the Casimir force, and the physicists at the scene blew it up!

One by one, it's like being trampled on the tail!

Can cassimely work it out?

impossible!

Absolutely impossible!

Physicists exploded in an instant!

The mathematicians over there, however, are confused.

What do they say?

What's the Casimir effect?

Did you work it out?

So what?

Why did those people suddenly get mad?

"Mr. Li, do you know what's going on?" Ma Luan asked with a dull face.

"I don't know. I don't know what I'm talking about." Old professor Li Shuwen is also muddled.

"Do you know, Professor delavin?"

"I don't know!"

"What did you say to figure it out?"

These mathematicians are so confused that they don't understand what they are talking about.

An old man with a more irascible temperament said impatiently, "Professor Ye, what can't be calculated? Isn't that power? Isn't that a good sum of all natural numbers? Since Professor Ye says that he can work it out, he can work it out! "

"That's what you make a fuss about!"

"Are you questioning Professor Ye?"

"I don't believe Professor Ye. What seminar are you going to attend?"

A group of mathematicians didn't understand, but it didn't prevent them from being sarcastic.

"You know shit!"

Professor Smith said angrily, "do you know what the Casimir effect is? Do you know what casimilli is? Ah? Don't talk to him if you don't know! "

Ye Feng's words had a great impact on them, and Professor Smith began to swear.

"We don't know, but we know Professor Ye doesn't talk nonsense!" Ma said

"Hum!"

Professor Smith did not answer this, but said coldly, "the Casimir effect is the natural result of quantum field theory. Do you know what quantum field theory is?"

President Ma snorted, hugged his arm and said, "do you know what Goldbach's guess is?"

Professor Smith lowered his face, instead of continuing the topic, he explained: "in quantum field theory, it is said that there is not nothing in the vacuum, that the vacuum is still full of energy. Quantum field theory quantizes the energy in vacuum, and the whole space is full of vibrating balls

A professor who is not studying quantum mechanics is a little puzzled and asks, "even so, what does it have to do with the fact that the Casimir force can't be calculated?"

Many people are puzzled by this. Why did those physicists explode after Professor Ye calculated the Casimir force?

Not only the mathematicians at the scene didn't understand it, but also some physicists who didn't involve this major didn't understand it.

Professor Smith continued: "to understand this, we must first understand what is the Casimir effect. The so-called Casimir effect is to place two very thin neutral metal plates in a vacuum, and the closer the two plates are, the greater the gravity will be generated. "

Speaking of that, a mathematician called out, "gravity? How do you know it's not gravitation? "

This immediately attracted the attention of many mathematicians!

I can!

You know that?

Many people gave him a thumbs up!

But Smith sneered and said, "gravity? Gravitation is quadratic, Casimir force is quartic, do you think it is gravitation? Do you have some common sense? "

“……”

The mathematician blushed in an instant.

Ma Luan said, "can you say the point directly? After all that, why can't you calculate it? "

Smith frowned, thought for a moment, and said, "well, the Casimir force is to subtract the energy in the interval from the energy outside the two metal plates. The difference is the value of Casimir force."

"Isn't that good?"

"What's the point? Ah Smith: "this thing, can't calculate forever!"

Situ yuan also nodded and said: "indeed, because you can't calculate the energy in vacuum, there are countless harmonic oscillators and waves in vacuum, which are infinite. No matter in a vacuum or between two metal plates, the harmonic oscillator is infinite. How can we calculate by subtracting one infinity from the other? "

"Infinity minus infinity?"

Hearing this, mathematicians immediately pick eyebrows, "you carefully talk about what kind of infinite?"

They feel the word infinity is a little familiar!

"Give me a concrete example." President Ma said: "how do I feel that it really can be calculated?"

"I feel the same way!"

"Really, I want to understand something."

"Me too."

These mathematicians didn't even understand the Casimir effect, but at this time they seemed to understand the meaning of Ye Feng.

Casimir force?

Infinity minus infinity?

This NIMA is so familiar!

"You can count? Oh

Professor Smith felt insulted. "When the gap between the metal plates is ten nanometers, you can calculate the Casimir force for me!" Smith is really angry, he is more angry than anyone else, because he is an authoritative expert in this field!

In the world physics, among the physicists who study quantum field theory, Professor Smith can definitely rank in the top five!

This Casimir effect, a phenomenon in quantum field theory!

Ye Feng said that he could work it out, and he could tolerate it a little bit, but these mathematicians also said that they could work it out?

It's your uncle!

You give me a look!

Smith directly gives the distance between the two metal plates, let us calculate!

How is that?

They don't even know what the Casimir effect is. It's impossible to work out just one distance!

But at this time, Ye Feng, who didn't speak all the time, said, "ten nanometers, right?"

"Well“ Smith squinted and said, "Professor Ye, do you want to do the calculation on the spot?"

"Yes."

The leaf breeze doesn't think of of of smile, say, opened multimedia.

When the computer screen is projected on the big screen, Ye Feng directly knocks out various symbols with his keyboard, including mathematical symbols and physical symbols.

To tell you the truth, I'm afraid Ye Feng is the only one who can skillfully use computers at the scene.

Soon, the big screen was full of formulas and numbers. String after string, many people's eyes are spent.

To tell you the truth, Ye Feng doesn't know anything about this ghost Casimir effect. But he knows how to count casimilli!

Because of this physical phenomenon, in the previous mathematical world, but the existence of famous!

The conclusion that the sum of all natural numbers is equal to minus one twelfth is verified by this experiment!

As Ye Feng continues to tap the keyboard, there are more and more formulas on the big screen.

At this time, physicists are looking at the frown, and they are familiar with these formulas used by Ye Feng. For example, the calculation of vacuum expectation of electromagnetic field in metal chamber, the calculation of standing wave, the calculation of zero point energy and so on are all known physical formulas in physics.

In fact, some people have done the calculation of Casimir force for a long time, and finally found that in the last and most critical step, there is no way to continue!

At this time, Ye Feng also calculated to the last step: use the standing wave energy in the vacuum to subtract the energy in the metal cavity, and the result is the Casimir force!

However, there is an unsolved problem. There are countless standing waves in vacuum. How to sum them? Similarly, there are countless standing waves in the metal cavity, which is a misunderstanding in the eyes of physicists!

In their opinion, this is to subtract innumerable from innumerable!

How does that count?

However, at this time, the mathematicians on the scene are boiling!

"I know!"

"That's it, I get it! I get it

"I've worked it out!"

"Isn't this the sum of natural numbers?"

"Negative one twelfth!"

"So it is! No wonder Professor Ye will study the sum of all natural numbers! It is needed here

"It's amazing! It's amazing

"It never occurred to me that a meaningless problem recognized by the mathematical community should be used here!"

"I just don't know if the result is right."

"Professor Ye must have calculated!"

"Yes, don't worry!"

Excited!

Boiling!

The shouts are going to lift half of the roof!

It's like mathematicians have discovered a new world! One by one excited howl!

In sharp contrast, it is the physicists on the other side. At this time, it's their turn to be confused. They haven't understood what's going on. Obviously, they haven't figured it out yet? What are these bastards excited about?

These physicists look at each other face to face.

However, the next second, these people were stunned!

On the big screen, Ye Feng brings in minus one twelfth directly, and then infinity is eliminated!

It's gone!

Fuck!

He's fake, isn't he?

"What's the situation?"

"Infinity?"

"Just, just gone?"

"No! The final result is absolutely wrong! "

"This, how can it be like this?"

Three seconds later, Ye Feng gave the answer.

All physicists are looking at the final number on the big screen - 101.3 kPa!

Professor Smith is struck by lightning!

President situ yuan was so stupid!

All the physicists who know quantum field theory are confused!

"Dean situ, is that right?"

"Professor Smith? Is that the answer? "

"Is the result accurate?"

"Is it much different from your measurement?"

"Right or wrong?"

"You have something to say!"

Those professors who don't understand are already in a hurry.

I saw Smith dull said: "and measurement results..."

"How's it going?"

"Say it

"What's the difference?"

"As like as two peas", Smith said with no eyes.

As like as two peas!

Hiss!

As soon as the words came out, everyone took a breath of cool air, and the whole auditorium became silent!

No matter these physicists or those excited mathematicians just now, they can't help swallowing their saliva and looking up at Ye Feng on the stage in shock!
