I really don't want to lie down and win

"Is there a master who is more capable?" Xu Mang sat in front of Li Aimin with a mean face: "It's not that Hu Jie went back to class, there just happened to be a vacant seat, and I want to give it to us at Fuda at this opportunity." In the physics department, select a so-called genius to explore gravitational waves together."

Hearing Xu Mang's words, Li Aimin's expression was very serious. He hurriedly turned on the computer and found all the students majoring in optics, including graduate students. A few minutes later... Li Aimin gave Xu Mang a list of five people.

"I am very optimistic about these five." Li Aimin said seriously: "Especially this Ren Panpan, who has participated in many research projects, if you need a helper, this Ren Panpan can definitely do it!"

"Ren Panpan?"

Xu Mang glanced at the profile of this senior student, not to mention... indeed, as Professor Li Aimin said, Ren Panpan's qualifications are particularly perfect, and two of the projects are national key scientific research projects .

"Not bad!"

"I'll talk to her in the afternoon." Xu Mang nodded and said seriously, "By the way...the gravitational wave detection project is about to start, Professor Li...what do you think is the probability of detecting gravitational waves? Can you win the Nobel Prize in Physics?"

"unnecessary!"

"The previous Xu Yang structure is enough to win the Nobel Prize." Professor Li Aimin glanced at Xu Mang, and said seriously: "Xu Mang... How sure are you that you can find gravitational waves? How long has this project been going? Almost half a year?"

"Yup!"

"It's been almost half a year." Xu Mang said with a smile, "I can't help it... I encountered an unsolvable problem, which I just solved a few days ago, but the price was that all my previous theories were overthrown, and then I restarted it." do it again."

words fell,

Xu Mang took out a USB flash drive, handed it to Professor Li Aimin, and said, "Professor Li, you are an optics expert, and I guess the same is true for equipment problems. Please help me solve this equipment problem? Laser interference equipment, how to prevent it?" How does seismic noise affect it?"

about this issue,

Xu Mang has never understood that exploring gravitational waves is actually looking for noise and a way to suppress noise. The way to find noise has been found. The peaks and troughs of light correspond to the maximum and minimum values ​​of the electric and magnetic fields. When the gravitational wave passes through the laser After that, it will be detected and record the position of its peak.

To put it simply...use the wave nature of light to measure the change of pulse arrival rate.

of course,

The specific content does not end in one sentence.

but,

Such a precise detection will definitely be interfered by the outside world. For example, Xu Mang has no way to solve this problem. Although he is very good at optics, his theoretical knowledge in equipment is still not comparable to it.

Insert the U disk,

Professor Li Aimin read the above content carefully, frowned, and then said: "Give me a week..."

"okay!"

...

in the afternoon,

Xu Mang called Ren Panpan in his office.

"Hey?"

"Hello there!"

"I'm Xu Mang...are you Ren Panpan?" Xu Mang's tone was a little serious. After all, he was looking for a researcher for the gravitational wave detection project. There would be no problem if he took it seriously. An opportunity for Xu Mang to take it seriously.

"..."

"fraud!"

"You said it's not good for you to pretend to be Professor Xu? Hehe...you can even imitate the other party's number?" The other party's tone was full of contempt, and then hung up directly.

Xu Mang: ￣￣;

what?

what's the situation?

Dude... Dude is a liar?

"Security awareness is very strong, not bad..." Xu Mang just smiled, dialed the number again, and then Xu Mang couldn't laugh anymore, he found that his number had been blacklisted by the other party .

at the same time,

Ren Panpan was staying in her dormitory, angry about what she had just encountered. Xu Mang was the object of her admiration. As a result, a boring liar pretended to be him, and used a virtual dialing software to simulate Professor Xu's number.

"what happened?"

"You look so angry after receiving a phone call?" Seeing Ren Panpan's angry look, a short-haired girl asked angrily, "You found yourself wearing a green hat? You're not the only boyfriend." Friend, he still has a wife and a child?"

"..."

"what!"

"It's not that you thought of it." Ren Panpan said helplessly: "I received a call from a liar who claimed to be Professor Xu...It almost didn't piss me off, Professor Xu is my idol, little love... .You said that liars these days are so big-hearted? Even Professor Xu imitated it?"

"Is there such a thing?" The short-haired girl named Xiao Ai pondered for a moment, and then said: "You show me the number, why do I think... this may be a misunderstanding? Are you sure it's a liar ?”

Ren Panpan nodded, and said seriously: "Although I have never been in contact with Professor Xu, it is rumored that Professor Xu is an unscrupulous person, but the voice just now was too serious, and he is completely different from the Professor Xu that everyone said. "

words fell,

Ren Panpan's phone rang, and it turned out to be his mentor.

"Professor Li?"

"Is there anything you want from me?" Ren Panpan asked respectfully.

"Professor Xu Mang, who majored in theoretical physics, has he ever asked you?" Li Aimin said with a smile: "At noon, he asked me for a person to do research on his gravitational wave detection project. Give him the opportunity to take advantage of it.”

Hearing Professor Li Aimin's words, Ren Panpan's mind went blank, and he tried to speak, but found that he couldn't say anything at all, and swallowed the words automatically when they reached his mouth.

No way?

Just now...is it really Professor Xu?

Not a liar?

"I..."

"He..." Ren Panpan squeaked for a long time before organizing his words: "Call...call me."

"That's good!"

"You can listen to him for specific matters." Li Aimin said.
