Ten consecutive draws at the beginning, let’s bring you the super-running mansion!

Chapter 630 Start the Debate!
In the midst of global sensation and anticipation, the debate competition kicked off at 4:[-] p.m. that day.

Li Jingtai stood on the stage, facing the camera.

At the same time, the global live broadcast has begun.

Song Yuwan smiled and said: "Everyone, good afternoon, thank you for watching this knowledge debate, I am your host Song Yuwan.

Now, let me introduce to you, this is Li Jingtai, a professor of physics at Huaqing University.He is the one who questioned the photonic chip and challenged the founder, Mr. Jiang.Let's first interview Professor Li.

May I ask Professor Li, how do you want to verify and question whether Mr. Jiang is the person who created the photonic chip today? "

"Ha ha!"

Li Jingtai laughed loudly when he heard the words, and then said: "This will be kept secret for the time being. I will wait for Jiang Chen to go online before revealing the truth! Let his physics scumbag face be exposed in front of everyone! Everyone will wait and see!"

After a while, the TV program team contacted Jiang Chen.

An avatar appeared on the screen behind, but the phone number was encrypted and not displayed.

"Because of Mr. Jiang's special status, we encrypted his contact information. Now we will connect with Mr. Jiang Chen and let him and Li Jingtai go online and confront each other face to face!"

Jiang Chen's phone was connected, and a familiar voice came out, "Hello, can you hear me? I'm Jiang Chen."

He tried the mic.

"Yes, Mr. Jiang, are you ready?"

Song Yuwan smiled and asked.

Jiang Chen nodded, and said calmly: "It's fine, you can start anytime."

"Okay! Then we will give the time to Professor Li Jingtai and Mr. Jiang Chen, let them bring us this, peerless duel!"

Like a referee, Song Yuwan skillfully controlled the field, and said to Li Jingtai: "Now, let Professor Li speak first!"

Li Jingtai seemed to have been beaten to the bone, and he fired with all his firepower as soon as he came up: "Jiang Chen! You just admit it! You are not a photon chip developer at all! Because I have studied your academic background, you have no scientific research experience at all. You don’t even have a degree that can support you to develop a super photonic chip that is 20 years ahead of the world! You must have made up a lot of money when you come to debate now, so you’ll be cramming when you come, right?”

Jiang Chen sneered: "Funny! Who said that without scientific research experience, you can't succeed in research and development? There is always a first time! You can't deny that there is a kind of person in this world called a genius! Just like me!"

clap clap clap! !

The audience, thunderous applause!
Li Jingtai is ashamed!
Hemp egg!

You are a genius, and your whole family are geniuses!
"Okay! I see that you are so confident, so I won't talk nonsense with you! I will ask you a physics question now. If you can develop a photonic chip, you should be able to answer it? If you can answer such a simple physics question If you don’t come up, it can only be said that you don’t live up to your name! You just admit that you didn’t develop the photonic chip. You just make the hidden information public and return the truth to the world, what do you think?”

Li Jingtai vowed.

"no problem."

Jiang Chen was calm and composed.

"Okay, you listen to the question."

Li Jingtai held back his strength, and immediately asked: "A plane flying horizontally at a speed of 3.0x102ms- collided with a bird with a length of 0.20m and a mass of 0.50kg. Suppose the body of the bird after the collision and The plane has the same speed, but the speed of the bird on the ground is so small that it can be ignored, please estimate the impact force of the bird on the plane?!"

After he finished speaking, he immediately sneered.

This question is actually not difficult, but any graduate student in physics can easily handle this question.

But Jiang Chen, he just graduated from an ordinary undergraduate, can he do it?

Jiang Chen smiled.

This question is about the application of the particle momentum theorem: it is too simple for him to find the average force with known velocity changes!

There was no fluctuation in Jiang Chen's heart, and he said calmly: "Isn't this question too simple? Taking flying birds as the research object, taking the direction of the plane's motion as the positive direction of the x-axis, and using the momentum theorem, F△t=mu-0, where F is the plane The average momentum of the bird. The 0 on the right side of the equation means that the initial momentum of the bird is negligible, and the collision time between a bird with a body length of 20cm and the plane is about △t=1/u, which can be substituted into the above formula to get F=mu= 2.55X10N, according to the reaction force and the law of reaction, the average impulse of the bird to the aircraft is -2.55X10N!"

The audience was silent!
Silent!

Everyone's eyes widened!
Simply, unbelievable!

Professor Li Jingtai was even more dumbfounded!

Because, Jiang Chen's answer was fast, precise and ruthless, it was simply a template for a standard answer!
How can it be?

Jiang Chen is just a liberal arts undergraduate student, how can he answer such difficult problems of advanced physics?Still answering so slipperily?
What he didn't know was that Jiang Chen rewarded a wave of skill packs a few days ago!

Among them are: [Advanced Mathematics Grandmaster] [Advanced Physics Grandmaster]

His current level of physics knowledge is not too high.It's just that he has mastered all the physics knowledge in the world, and is twice as powerful as the strongest physicist in history!
Take Einstein as an example, Jiang Chen's current level of physics is more than twice that of Einstein!
This kind of advanced physics topic is simply pediatrics!

Ban Men get an axe!
"Li Jingtai, Mr. Jiang Chen has already finished answering, is the answer correct?"

Seeing that Li Jingtai hadn't spoken for a long time, Song Yuwan asked with a smile.

Only then did Li Jingtai come to his senses, and said with an ugly face: "Uh, almost, I barely got the answer right."

"Right is right, and wrong is wrong. You can barely answer right? It seems that Professor Li is quite stubborn, it doesn't matter, I will convince you!"

Jiang Chen was not polite, and directly provoked Li Jingtai.

Li Jingtai blew his beard and stared angrily, and said, "You! Don't get carried away, isn't it just to let you get away with answering one question correctly? I have other questions!"

"Let the horses come."

Jiang Chen scratched his ears, with a calm expression on his face.

"Listen to the questions!"

Li Jingtai frowned, his mind turned sharply, and he started to ask the question again: "The first artificial satellite launched by our country in 70 years has a perigee of 4.39X10m and an apogee of 2.38X10m. Please calculate the speed of the satellite at perigee and apogee !"

This physics problem is more difficult than the previous one, and it involves many physics knowledge points, and there are a lot of calculations. He forced Jiang Chen to answer the mental calculations in a short time, and there must be loopholes. Then he will take the opportunity to ridicule Jiang Chen.

Who knows!

After Jiang Chen listened to the question, the answer in his heart seemed to be on the paper, and he said directly:
"Can you make it a little more difficult? Isn't this question too easy?"

"Remember that the distance between the satellite and the earth at the perigee is R1, and the speed is U1, and at the apogee they are R2 and U2 respectively. Since the orbit of the satellite around the blue star is an ellipse with the blue star as the focus, and the velocity direction at the perigee and apogee is the same as that of the blue star The line connecting the star to the satellite is perpendicular, then the law of conservation of angular momentum has mr1u1=mr2u2, that is, U2=r1/r2*U1, and because the mechanical energy conservation of the satellite and the blue star system is inherent.”

Jiang Chen performed precise calculations, accurately stated the extremely complicated calculation process, and finally came up with the answer:
“将蓝星和卫星的质量代入上式，则U1=8.11X10m·s-，U2=6.31X10m·s-”

Li Jingtai's shocked eyeballs fell off!

I wiped it!
What is going on?
This Jiang Chen, why is he so awesome?
This question tested the conservation of angular momentum, the function of gravitational potential energy, and the conservation of mechanical energy, which is a very complicated physics knowledge point!
And Jiang Chen was able to answer the questions fluently!
No mistakes at all!

It's also mental arithmetic and oral arithmetic!
At this level, as a researcher, there is absolutely no problem!
Seeing that Li Jingtai was closed to himself again, Song Yuwan smiled and said, "Professor Li, what are you talking about, is Jiang Chen's answer correct?"

Li Jingtai: "."

Before he could answer, many netizens in front of the live broadcast were completely excited!
Watching the live broadcast, there were many big physics experts, and they were all shocked after hearing Jiang Chen's answer.

Leave a message!

"Yes! Brother Jiang's answer is at the textbook level! The perfect of perfection!"

"My God, I can't understand a single word of what you're saying, it's too profound!"

"Give me time for this question, and I can figure it out, but I'm sure not as fast as Mr. Jiang! His thinking is not as clear as his! His speed at solving the question is simply terrifying!"

"Master Jiang! You are indeed the leader in the research and development of photonic chips! This is a proper scientific research leader! You can be so good at mental arithmetic, so you don't have time to make drafts?"

"That's awesome! Boss Jiang, I'm your fan!"

"Hahaha, I saw that Li Jingtai shut himself up! I asked two questions, but they were answered in seconds!"

"Large rollover scene!"

"Professor Li lost, don't you want to eat some keyboards, eat something? How boring."

"."

"Okay, okay! I admit it! Jiang Chen, you do have something!"

Li Jingtai gritted his teeth, his eyes were obviously bloodshot, he was going to fight this time!

Never ask physics questions of this level again!

He is going to make a big move!

Li Jingtai held back for a long time, finally showed a sinister smile, and said: "The two questions just now are appetizers, and now I want to ask you a more advanced advanced physics problem! Do you dare to take on the challenge?"

Jiang Chen smiled lightly and said: "Hehe, just ask casually. If I can't answer, there is no one in this world who can."

Li Jingtai was surprised.

Why is this guy so confident?

Song Yuwan beside her also opened her eyes wide in shock.

Jiang Chen, is he a god of learning?

How confident are you?

"Okay! Please listen to the questions!"

Li Jingtai said angrily: "."
