Time flies.

In late June, the results of the college entrance examination were finally released.

The family gathered in front of the computer, accompanying Xiaotong with a worried face.

This feeling is almost like betting on the World Cup.

Xiao Tong looked nervous, and turned his gaze to his brother next to him.

"Dude......"

Lu Zhou calmly patted her shoulder: "Don't be afraid, I'm not afraid to hand in the papers, I'm still afraid of the rolls." ”

"Hmm......"

Xiaotong hesitated, and finally took a deep breath and entered the candidate number and admission ticket number.

The score quickly appears on the screen.

The moment he saw the score, Xiao Tong's whole person seemed to have been petrified, and he was stunned.

Not because it was below her expectations.

It's because ......

620！

Happiness came so suddenly that Xiaotong screamed in excitement.

"Dude!! I took the 620 !! ”

"Well done, worthy of my sister."

Seeing this score, Lu Zhou nodded with satisfaction, sincerely happy for his sister.

The 16-year-old liberal arts line is 520, which is 100 points higher than the first line. Although it can't compare to the amplitude of the line that he threw off at the beginning, it is also quite strong.

It may not be enough to apply for Shuimuyan University, but Jinling University is still very stable.

"Haha, it's worthy of being my daughter," patting Xiaotong's head, Lao Lu laughed and said with satisfaction, "I'll go out and buy a snack." ”

Fang Mei glanced at him, and said, "I drink at noon, and I don't want to go to the unit in the afternoon?" ”

Old Lu Le couldn't close his mouth: "No, I asked for leave with the leader!" Don't go to work today! ”

Both children were admitted to college, and at this moment, Lao Lu only felt that he was the happiest person in the world. On this festive day, how can you miss a glass of liquor?

The only regret is that Lu Zhou's kid has been out for so long, and he has even mixed into the territory of foreigners, and he has not seen him bring a daughter-in-law back.

When will he be able to hold his grandson, Lao Lu feels that there will probably be no regrets in this life!

Throughout the day, the family felt like a holiday.

Even the next day, Lao Lu was not happy, and proposed to set up a table to celebrate the banquet and entertain relatives and friends.

However, Xiaotong was afraid of trouble and a waste of money, so Lao Lu had to give up.

In the evening, after arranging tomorrow's interview plan, Lu Zhou glanced at his sister who was lying on the sofa and asked casually.

"Have you figured out what major to apply for?"

Just after the end of the pit, Xiaotong put down his phone after spraying his teammates, seriously considered the problem, and spoke.

"You've figured it out!"

Lu Zhou: "Oh? ”

Xiaotong nodded and said with a firm face: "I plan to report finance!" ”

Finance is considered a liberal arts and sciences major at the University of Jinda, and both liberal arts and sciences can be reported. Although a certain mathematical foundation is required, if you do not develop in the direction of theoretical research, you will definitely not memorize much of the things to be calculated.

The most commendable thing is that Xiaotong finally has his own ideas, instead of asking for help as soon as he encounters a problem.

This is also the most gratifying for him.

Lu Zhou nodded approvingly: "If you have an idea, can you tell me why finance?" ”

His eyes were shining, and Xiao Tong said without hesitation: "The name of finance looks like a lot of money when I hear it!" ”

Lu Zhou: "......"

What do you say?

Except for the fact that it doesn't look like it.

Elsewhere it's a statue of Nyima!

Lu Zhou: "Actually, alchemy is also quite rich, you hear the name metallurgy, it is similar to alchemy." ”

Xiaotong looked confused: "Huh? Are you sure? ”

Lu Zhou: "Lied to you." ”

Xiaotong: "......"

……

Some people are happy, some people are naturally worried, the college entrance examination is such a realistic thing.

On the day of filling in the volunteers, the students who had been liberated in the computer room of a high school in Jinling gathered here again.

It is said that in the past, they had to fill in the application on paper first, and then the school entered it into the computer, but now their high school fills in by themselves.

Looking at the volunteer form on the computer screen, Han Mengqi pursed her lips and didn't move the mouse for a long time.

Fortunately, she successfully got double A's in two science subjects, but her score was on the edge of the admission score of Kim University.

To be precise, her score is enough, but whether she can report it or not depends on how many people report this year.

Mathematics......

The Department of Mathematics at Jinling University does not seem to be a strong major.

There aren't many people who have reported in previous years......

Swallowing and spitting, Han Mengqi made up her mind, and finally filled in the number of Jinling University and applied mathematics major on the website.

As for the option to accept the adjustment, she didn't want to tick it, but after hesitating, she finally ticked it.

"You must report it......"

With her eyes closed, the girl's small hands clenched in front of her chest, and she prayed silently.

……

Staying in China until July, Lu Zhou's holiday is almost coming to an end.

Although he wanted to wait until Xiaotong's admission letter came down before leaving, it was troublesome to extend the vacation, and he still had things to go back to deal with, so he wouldn't stay in the country longer.

After a dozen or twenty hours of traveling, Lu Zhou finally returned to the quiet town of Princeton.

For most American college students, it's still summer vacation, and it will run from June to the end of August.

However, for master's students, the school's regulations are the school's regulations, and the boss has the final say on when to return to school.

In a sense, the rights of American tutors are much greater than those in China, because tutors have the right to directly expel graduate students, while in contrast, domestic tutors will only block you from graduation at most even if they see you unhappy, because the right to expel students is in the hands of the school, and it is generally not used.

It's just that relatively, there are many factors of checks and balances in power, but this is not mentioned for the time being.

Of course, Lu Zhou will not be the kind of unscrupulous tutor who oppresses students, but he will not make it easy for them.

According to his request, the three master's students who received offers from him will arrive at the school before July 15 to report. If it's a visa issue, he can grace it until August, but it's best not to delay it too long.

Before assigning them a job, he needs to meet them first and get to know them.

Leaving his luggage in his apartment, Lu Zhou went to the Institute for Advanced Study.

On the way upstairs, I happened to meet Edward Witten. As soon as Lu Zhou said hello to him, he greeted him with a look of surprise.

"My friend, you're finally back."

Confused by Mr. Witten's warm welcome, Lu Zhou couldn't help but ask suspiciously, "...... What happened? ”

Edward Witten smiled mysteriously and said only one word.

"Gravitational waves."

Hearing this word, Lu Zhou finally reacted and understood what Witten was talking about.

In fact, as early as February 16, the researchers of the LIGO project team announced that they had successfully detected gravitational wave signals from the merger of two black holes using two detectors of LIGO.

The paper, which was recently published on Arxiv, is being reviewed by theoretical physicists around the world.

Although Lu Zhou has been on vacation for the past month, he is not completely out of touch with the dynamics of the academic community, and is always paying attention to new articles on Arxiv.

Even though not every article on Arxiv is useful, the sudden spike in the number of articles in a certain area is telling.

Just like last year's 750 GeV, gravitational waves are the hot topic in theoretical physics this year.

Lu Zhou's tone was a little envious: "It's really ...... A surprising find. ”

Compared with his "insignificant" discovery, gravitational waves are undoubtedly much more shocking.

"yes, it's enviable." Witten said with heartfelt emotion.

The successful discovery of gravitational waves fills in the last missing piece of the puzzle in the experimental verification of Einstein's general theory of relativity.

If Einstein were still alive, he would surely win another Nobel Prize in physics for his general theory of relativity with this great discovery.

After all, he won the award for his success in explaining the photoelectric effect, not the obviously greater general theory of relativity.

But this is obviously impossible, because 74 years later, the Nobel Prize Committee ruled that Nobel Prizes should only be nominated by living people. Even if an exception is occasionally made to a particularly significant discovery, it is not possible to make an exception like a deceased person.

For the feeling of gravitational waves, Mr. Witten is probably the person who feels the deepest.

It took 100 years for experimental physics to find this piece of the puzzle in the theory of relativity, and if this trend continues, his string theory will never see the day when it will be confirmed by experiments in his life.

Next year's Nobel Prize in Physics, with little suspense, must belong to MIT's Reyner Weiss and his collaborators.

After all, the discovery of gravitational waves can be engraved on the milestones of human history.

After stopping his emotion, Witten cleared his throat and continued: "Regarding gravitational waves, LIGO invited me to help them do data analysis, I guess you shouldn't have any topics to do now, I wonder if you are interested in joining my project?" If you're interested, I can ask my students to book your flight right now. ”

Lu Zhou thought about it, and finally politely rejected this very attractive proposal: "Gravitational waves are not within the scope of my research, unfortunately I can't help, and I will probably be busy in a few days, and I can't spare time." ”

The reward tasks of the system gave him a lot of freedom, and for the sake of efficiency, it was obvious that it was best to improve the materials science at a lower level.

Moreover, it is very likely that the topic proposed by Professor Witten does not involve the core research content of gravitational waves, and the experience of task reward is closely related to academic value.

Don't look at the proposition of gravitational waves, which is big enough, but maybe in the end, according to the experience of the academic value of the paper, it will not be enough to make up even 10,000 yuan, then it will be a big loss.

Witten: "The subject of materials science?" ”

Lu Zhou nodded: "Yes." ”

Witten sighed and said regretfully, "Okay then, it looks like you've got the arrangements, good luck." ”
