"Oh yes, I said I always felt like something was missing. Professor Rudolf Wagner exclaimed, "Boss, Brother Yun, why didn't you say it earlier?"

The level of the professor is above that of Yanagisawa, who looked at the formula on the table and exclaimed.

The people around cast surprised eyes.

A blonde foreigner speaks standard Northeast dialect, which is not common anywhere. Especially the professor is so flamboyant, not subtle at all, and full of highlights.

"It also has to do with temperature, and this formula is only the most preliminary. Zheng Ren continued: "The specific formula is too complicated to say, and I don't think Dr. Mehal has it in mind. ”

"Temperature?"

"Lao Liu, the viscosity coefficient of body temperature of 36.2 °C and 37 °C is not the same. The higher the body temperature, the smaller the viscosity coefficient and the different the actions of the operation. Su Yun smiled and picked up a piece of meat and said.

"Richard Feynman said that turbulence is the last bulwark of classical physics. "Baron Kelvin spoke confidently at the annual meeting of the Royal Academy of Sciences on the last day of the 19th century, saying that the edifice of physics had been built, and that all that remained was some partial tinkering. ”

Liu Zewei was directly stunned.

It's just an interventional operation, can you use classical physics? Next, do you want to talk about quantum physics?

Sure enough, his prediction came true.

"Newton's three laws of mechanics, Kepler's three laws of celestial motion, the three laws of thermodynamics, and a bunch of Ohm's theorem, Lenz's theorem, Coulomb's theorem, Joule's theorem, these have almost built the edifice of physics. Oh, yes, it's classic physicality. Zheng Ren said: "But there is another problem, which has not been solved after the emergence of quantum physics - turbulence. ”

Zheng ...... Boss Zheng ......, "Liu Zewei really doesn't understand, he can't remember Newton's laws clearly, and his mind is full of that idea - it's just interventional surgery, is it so high-end?"

"Lao Liu, what's wrong?" Zheng Ren seemed to be thinking about something, and he just asked casually.

"Turbulence? is the turbulence in the flow of water......? Is it difficult?" Liu Zewei knew that he would definitely be ridiculed if he asked, but if he didn't ask, he would not be sure.

"Heisenberg said before he left that when I saw God, I would have to ask him two questions. One is about relativity and the other is about turbulence. By the way, do you know Heisenberg?" asked Zheng Ren naturally.

Yanagisawa burst into tears.

Is he too mentally retarded, Boss Zheng even asked himself this question. Heisenberg, how could he not know.

It's just that before he could speak, Su Yun began to explain.

"The main founder of quantum mechanics, a representative of the Copenhagen School, and a winner of the Nobel Prize in Physics in 1932. Boss, I think the reason why quantum mechanics has not made a breakthrough is related to turbulence. Su Yun was eating meat and drinking the deadly Da Wusu while making a lot of nonsense.

"Dr. Su, wait a minute, I've returned all my physics to my high school teacher. Liu Zewei was not embarrassed at all, he knew that what he said today should be very important.

Zheng Ren was also a little surprised, the turbulence was only understood after he reached the peak level of interventional surgery. Dr. Mehal should have only a little idea, very hazy.

But Su Yun is a good thing, eating, drinking and having fun every day, how does he know about turbulence?

Zheng Ren sighed in his heart, genius is genius, from cardiothoracic surgery to intervention, Su Yun's eyes are still sharp, and he can see the essence of the problem at a glance.

"It's called Brother Yun, what Doctor Su. Su Yun raised his wine glass, touched it with Chang Yue, and drank it all, full of spirits.

"Uh......" Yanagisawa has always rejected the title.

But now, he really couldn't refuse anymore. Academically, those who reach it are respected. People can't understand the operation, they can't understand the principle, what else is there to be reserved?

"Boss Zheng, Brother Yun, what is turbulence, and how is it reflected in interventional surgery?"

Zheng Ren didn't speak, and glanced at Su Yun.

Su Yun explained as he poured the wine.

"To understand turbulence, you have to understand laminar flow of blood. To put it simply, it is the flow of blood in layers. The previous law of stickiness was about this.

When the flow velocity of the fluid is very small, it does not move forward as a whole, but does not mix with each other, and flows layer by layer. As the flow velocity gradually increases, the fluid begins to oscillate in waves.

The frequency and amplitude of the oscillation increase with the increase of the flow velocity, and at this time, it is called transition flow.

As the flow velocity continues to increase, the streamlines become invisible, vortices begin to appear, and the laminar flow is disrupted, and there is not only slippage but also mixing between adjacent flow layers. This is called turbulence, turbulence, turbulence or turbulence. ”

Zheng Ren smiled.

Su Yun really knows this.

Tomorrow, he will definitely be put on stage in a lead suit. Want to hide? No way!

Thinking of this, Zheng Ren beckoned and called the beer girl.

"I'm sorry, ten bottles of beer were withdrawn. Zheng Rendao.

"Boss!" Su Yun screamed.

"Sir, sell ......" the beer girl's face was ugly.

"It's okay, the money is normal, I invited you to drink. Zheng Ren said with a smile.

The beer girl was relieved.

"Boss, what are you going to do!" Su Yun said through gritted teeth.

"There are so many fusels, don't make you stupid. Zheng Ren said expressionlessly: "Tomorrow afternoon, follow me for surgery." ”

"Isn't it Fugui'er?"

Su Yun and Professor Rudolf Wagner set their sights on Zheng Ren together. Liu Zewei was still looking at the formula on the table that had faded in a daze.

"The level of rich and noble children is still poor, for the sake of the Nobel Prize, it is more stable. Zheng Ren said: "When did you understand turbulence?"

"When Pengxi Township had surgery. Su Yun said: "At that time, Mu Tao's operation was basically flawless, he couldn't hit him, and he didn't have the energy to do the operation." So I thought, it's nothing hard to think about. ”

So that's the case, Zheng Ren was speechless.

"Boss Zheng, you continue. Liu Zewei didn't notice what everyone was saying, but looked at the formula intently and asked stupidly.

The bald top exudes a sheen, oily and shiny.

"In physics, turbulence is not limited to water flow, so it's called fluid mechanics, which includes both liquids and gases, for example, drinking milk with some coffee. ”

"The clouds outside the sky are rolling in the clouds, Caigen Tan has always seen it. Su Yun added all the anger of not being able to drink to Liu Zewei's body, his tone was also a little sour, and he glanced at Liu Zewei's baldness and said, "Old Liu, it's okay to read more books, it's good for you." ”
