Chapter 470: Test Xu Mang

what?
Physics?
But looking at the calculation process, it's not like a physics person, but a math person.
This is not the illusion of the two of them. Although those who do physics are not bad in mathematics, it is a world of difference compared with those who study mathematics purely. It is also powerless.
Seeing the bewildered expressions of the two of them, Martelli said calmly: "You should be able to guess."
"..."
"..."
should?
It seems that this person is near us.
Dean and Bill looked at each other, and both knew the name the other wanted to say.
"Correct!"
"This person is Xu Mang!" Ma Terri said seriously: "You can't imagine what I have seen before... I saw a beautiful performance, a waltz from the tip of a pen, so... Professor Xu calculates the problem like this."
This...
Why her look and words... a bit scary!
"Do you think...how much time does it take to face this problem?" Ma Terri asked.
"Three days!"
"It will take at least three days, of course, provided that my math matches the problem." Dean's statement was very sincere and did not hide anything. In short, with his current ability, he couldn't solve this calculation.
"Bill?"
"How about you?"
"Me?" Bill thought for a moment, then shook his head, and said helplessly, "I guess not."
Get an answer,
Ma Terli's expression is still very serious: "None of us can solve this problem... But from the moment Professor Xu got the pen, he only took less than half an hour, accurately Say about fifteen minutes."
"???"
"???"
ten minutes?
The whole problem is solved?
How is this possible? It takes three hours to solve the relationship between the dielectric washing of the optical solution medium and the frequency of the incident electromagnetic wave. This...this is 15 minutes to solve?
And it's not just such a problem.
This...too strong!
Dean and Bill knew that Xu Mang's mathematics was very powerful, but it was so powerful that it was a bit too much, and was completely unscientific.
"I have a way!"
"Let's hand this question to the professors in the mathematics department to see what their minimum time is." Dean laughed and said, "Trust me...this is definitely a fun game."
Immediately after,
Dean found his two mathematics friends, Henry and Joseph, who had little success in the field of mathematics.
"This...so complicated?"
After the mathematics professor Henry got the problem, he said with a look of confusion: "The solution of this formula... is very complicated. It needs to be split at least four times, otherwise it will not be solved at all."
"of course!"
"If it's easy, do you need to come over?" Dean smiled: "Hurry up."
"Forget it in the morning."
"It will take at least half a day." Professor Joseph said: "I will show you the process before get off work."
long time?
It seems that the guess is quite accurate.
Dean shook his head and said indifferently: "No need... Actually, we asked you two to come over, just to know how long it takes to solve this problem in the eyes of your professional mathematicians."
"just now..."
"We roughly understand the gap between the two sides." Dean said.
gap?
What gap?
About the gap in mathematics?
Facing mathematics,
Henry and Joseph were very confident, and Joseph laughed: "Do you feel helpless, why is the gap so big? Actually...it's nothing...after all, our field is professional mathematics."
"..."
"..."
"..."
in case,
He may have accepted his fate before, after all, he is not an opponent.
Now the three have the capital to fight back, and this capital comes from Xu Mang.
"If I tell you... there is a theoretical physics professor who solves all the problems in just fifteen minutes, believe it or not?" Dean asked.
"Dean!"
"This kind of joke is not funny!" Henry said solemnly: "There is no such person in the world, fifteen minutes... Is it possible that he is an advanced alien intelligent life form?"
"You're right!"
"This person is non-human." Dean nodded, "Professor Xu Mangxu knows? Recently, in our school, I worked with Professor Will on gaseous cyclocarbon."
"know."
"You physical people."
The voice just fell,
Henry reacted and said in horror: "You...you mean this person is Professor Xu Mangxu?"
The three nodded.
"impossible!"
"How could you guys in physics be so proficient in mathematics?" Joseph hurriedly retorted, "I don't believe it anyway."
Facing such stubborn two people, the three physics professors decided to call out the legendary Xu Mang in a banquet, and then show his unparalleled mathematical talent in front of them.
quickly,
The offer was accepted, roughly tomorrow night.
Seeing the two people leaving behind, Bill suddenly reacted and asked curiously: "Say, Professor Xu is looking for you to help you solve your problems?"
"No, no, no."
"He came to see STM." Ma Terri said: "Then I briefly explained the principle of STM to him."
"STM..."
"Professor Xu intends to experiment with STM?" Dean asked curiously: "Technically it is not possible...it is difficult to do it."
indeed,
It’s difficult to use STM to implement this technology. It’s not that no one has tried it before, but they have all failed. Of course, there are also successful cases, but the atoms are extracted separately, but what Xu Mang has to do is arrange the carbon atoms and One-key and three-key alternate connection.
but,
With the previous experience, Dean just said it was impossible, but there was still a theoretical possibility, after all, the other party was Xu Mang.
...
at this time,
Henry and Joseph went back to the office and narrated the matter with other colleagues. What they got was some ridicule. It was a bit whimsical to solve the problem in 15 minutes. Although the problem is not difficult, the process is quite complicated.
fifteen minutes?
impossible.
"Henry?"
"I think you were deceived physically." A young man said, "It may be Xu Mang took a few days to complete, but Dean told you that it was completed in 15 minutes. I think ...Maybe this is the case."
quickly,
The vast majority of people agreed with this view. Although Xu Mang was very powerful, he was definitely not that powerful.
fifteen minutes,
Divide a long formula into four times, untie it one by one, and then simplify the long formula based on the results of the four times to reach the final solution.
"The two of us and Dean have made an appointment tomorrow night to invite Professor Xu to a private dinner together. Joseph and I will test Professor Xu's mathematics talent!" Henry said, "Do you have any comments? Or provide some difficult ones? problem."
"Yes!"
"I just had a partial differential equation to be solved. One of their physics researchers asked me to solve the problem, or else..." The young mathematics professor laughed and said, "Let Professor Xu try it? "
Partial Differential Equations?
this is okay!
Subsequently,
Everyone studied this partial differential equation problem and agreed to leave this problem to Xu Mang to solve, to see if he has an incomparable talent in mathematics, as Dean said.
"this problem..."
"It will take at least one day for me to solve it!" Joseph said seriously, "I don't know how long Professor Xu will take."
"in case..."
"Dean is not wrong, so it will take half an hour." The math professor who provided the question smiled: "Half a day, he only took fifteen minutes, so a day is not half an hour."
half an hour?
Ha ha...
Hearing this time, everyone present laughed.
at the same time,
Xu Mang is staying in the laboratory, discussing STM issues with Professor Will.
"This..."
"Reduce the temperature to a few K, and then STM can perform precise manipulation of atoms?" Professor Weir frowned, and said incredibly: "This seems to have some myths."
Xu Mang nodded and said seriously: "How can I know if I don't try? I will conduct special research based on the working method of STM, combined with a temperature of a few K, and study the possible probability."
Although Professor Weir did not believe in this matter, Xu Mang gave the project a new rebirth.
"need my help?"
"Need!" Xu Mang said seriously: "I still don't understand STM."
after that,
Professor Xu Mang and Professor Weir began to design the theory of STM manipulation of atoms, but Xu Mang never thought that this is so difficult... it is unimaginable. How does the temperature combine with STM? Has caused him a headache.
finally,
Xu Mang gave up the idea of ​​joint development of the theory and equipment structure, and directly chose the theory. The engineer has the final say.
It is theoretically possible anyway.
The next day,
Xu Mang is still calculating how many K can make the atoms and bonds in the molecule have a stable effect. At this time, the arrival of a person broke his next thinking.
"Professor Xu?"
"Why are you alone?" Dean smiled and came to the laboratory. After seeing Xu Mang, he asked kindly: "Where is Professor Will?"
"I went to class for the students, what do you mean?" Xu Mang looked at him curiously.
"I'm Dean."
"The same as you in theoretical physics." Dean said: "Is there time tonight? We plan to invite you to a dinner party."
"Where?" Xu Mang asked.
Dean hurriedly said: "Macdonald Rudolph Resort!"
Uh?
Isn't this my home?
Xu Mang was stunned for a moment and nodded: "I'll stay in this hotel, so let's contact me then."
"it is good!"
...
4:30 in the afternoon,
Dean and Bill went to the hotel in formal attire, and under the leadership of the waiter, came to their table.
"Henry?"
"What kind of problems are you going to pose for Professor Xu?" Dean asked curiously.
"It was kept secret, but...you can't solve this partial differential equation." Henry took out a note generously with a very simple formula written on it, which didn't look very long.
This...
This seems to be about the fixed field problem of astrophysics.
It's hard!
Almost all such problems are solved by mathematicians~EbookFREE.me~ and based on past experience, they need several days.
"Henry!"
"You are too much!" Dean said helplessly, "This...this is cheating!"
"test!"
"Of course it is a little harder." Henry smiled: "What? No confidence in Professor Xu?"
Not to mention,
After Dean, Bill and Martley saw this problem, they instantly lost confidence in Xu Mang. It was not that they didn't trust him, but that the other party was too cunning.
