Xueba's Sea of ​​Stars

Chapter 168 The end of the competition
Before the experimental competition the next day, Wu Bin took a special look at the big Western brothers who invited them to the party, and found that they were all in high spirits, without the slightest sign of a hangover, which made him sincerely curious about what Western High School was like. magical place.

For the experimental questions, the students were divided into two groups. Wu Bin was in the morning group, so he entered the laboratory early to prepare.

There are two experimental questions, the first question is [Diffraction caused by helical structure]

The famous X-ray diffraction image once taken in Rosalind Franklin's laboratory, known as "Photograph 51"

And it later became the basis for the discovery of the double helix structure of DNA by Watson and Crick in 1952.

In this experiment, in order to help candidates understand, the diffraction pattern produced by the helical structure with visible light was specially used instead.

In addition to the test questions, there are also experimental devices such as a laser source, a DC stabilized power supply, left and right mirrors, digital vernier calipers, a 1.5m tape measure, and laser protective glasses.

'Determine the geometric parameters of the helical spring...'

After reading the requirements of Experiment A, Wu Bin began to inspect a pair of guide rails, lasers and reflectors fixed on the wooden platform.

'Well, the laser wavelength of the laser source is λ=635nm, and the laser is connected to the bearing and fixed on a metal bracket that can be adjusted along the xyz direction...'

After testing all the experimental devices, Wu Bin began to check the helical spring as a sample.

'Radius R, period P, uniform thickness of the line a. '

Then he took a look vertically to make sure all the lines were the same thickness.

'The distance is d, and the angle between the two groups is 2a'

Nodding thoughtfully, Wu Bin fixed the spring on the sample holder.

Then there is a smooth operation.

Adjust the focus of the laser beam, the direction of the beam, press the switch on the power supply to change the laser intensity to high...

【由（xn-x-n）与ｎ比值确定a，由最小二乘法或作图法求得图A1的直线斜率为kA1= 23.55mm，a=kA1分之2λD=23.25分之2x0.000635x2770=0.151mm……】

After recording the relevant distances measured by the digital vernier caliper one by one, Wu Bin started drawing.

……

And Wu Bin didn't know that when he was doing his best, the professors who were in charge of proctoring the examination seemed to be dumbfounded.

'This Huaguo student doesn't need to think! ? '

'This is a leak! ?No, I don't dare to vent the question so blatantly and so quickly. '

'Wait a minute... isn't this guy the same guy who ate snacks during the second half of yesterday's theory test?What kind of little monster did China send this year? '

……

When several professors were so surprised that all their eyes were focused on Wu Bin, Wu Bin had already completed the requirements of experiment A, and started to do experiment B to determine the set parameters similar to the double helix structure pattern.

'HOLY...'

After feeling a headache, the professors stopped looking at Wu Bin and went to patrol other candidates.

After all, at Wu Bin's speed, either he knew the topic ahead of time, which is beyond their control, or he has already gone through the experiment in his head, and the rest is to complete it, which is really nothing to look at.

However, the facts are indeed as expected by several professors. Experimental questions have always been Wu Bin's specialty, and he did not relax on experimental questions because he is good at experimental questions. On the contrary, during his days in the training camp, absolutely most The time is soaked in the laboratory, why?
Because it's fun!
For Wu Bin, the joy of a successful experiment is even more than solving a difficult problem, which can be enjoyed for a while, so he can't stop.

After completing the first experimental question smoothly, Wu Bin looked at the second one.

[Diffraction caused by surface tension waves of water]

On the liquid surface, the formation and propagation of waves has always been a very important and widely studied phenomenon. In 1979, G. Weisbuch et al. first proposed the use of liquid surface waves to line-sight light diffraction, and established the surface tension For such waves, the restoring force of the oscillating liquid is partly gravity and partly surface tension...

After reading the long title, Wu Bin couldn't help but sigh in his heart.

'Professor Song's translation skills are really solid. '

In competitions such as IMO or IPHO, the translation skills of the team leader can be said to play a very important role.

In previous competitions, there are definitely not a few candidates who overturned due to insufficient translation by the team leader. Even students from some countries chose the English version of the topic with tears in their eyes after reading the native language translated by their team leader. Who to tell.

After reading the questions, Wu Bin operated the tablet computer with the sine wave generator program installed, then unplugged the black laser lead and inserted the white laser lead into the DC power jack.

Because laser 2 was marked on the test questions, that is, the white laser had been adjusted to a special angle of incidence, so Wu Bin no longer touched it.

After another skilled operation, Wu Bin completed the adjustment of the experimental device and began to measure the angle θ between the laser beam and the water surface
"how come..."

Seeing that Wu Bin had started to use the second set of experimental equipment, an American brother next to him was about to lose his temper. He was still recording the second question of the first experimental question, okay?Is the gap really that big? ?

Wiping the fine sweat from his brow, the big American brother made a sign of the cross on his chest, continued to do his own experiments, and vowed never to look at the next door again.

[0.069.θ=4.0°] After filling in the slope of the straight line in the experimental data, Wu Bin started the last experiment to determine the surface tension σ of the given water sample

'Tsk... The experimental questions in the international competition are really interesting, and it's a pity to finish them so soon. '

While calculating the relational formula, Wu Bin felt pity in his heart, and then went to make a graph for the variables.

"call……"

An hour later, Wu Bin breathed a sigh of relief, took a bite of the cake provided by the organizer, and relished the sweetness in his mouth and the refreshing feeling of completing the experimental questions.

"Cool……"

Hearing Wu Bin's voice, the big American brother next door couldn't help but turned his head to look at him after all, and then silently read a word beginning with F.

Although he couldn't understand what Wu Bin said, Wu Bin's expression told him that he was in a very good mood now.

'Are all Chinese so perverted...'

After crossing his chest again, the big American brother continued to record his data.

……

When the invigilator announced that the experimental questions were over, Wu Bin found that there were still many candidates whose experiments had not been completed, which reminded him of what Senior Brother Wang Gaojie said to him yesterday.

"Do you think that every country is like Huaguo, with preliminaries, semi-finals, and finals, and finally the top five will be selected from the national team training camp to participate?"

"No! Many countries have elected five representatives in two rounds, but this is also related to the population base."

Although in the 21st century, many things no longer depend on the strength of the number of people, the population base is still a huge national advantage. Take Hua as an example. When it breaks free from the shackles of food stamps, it is tantamount to announcing to the world .

"I've already raised 11 billion people. The ones in front of me have to clean their necks and wait for me to catch up!"

If you can't find a genius out of 10 people, then choose from 100 people, if you can't choose a genius from 100 people, then choose from 1000 people!
This is the biggest advantage of a country with a large population, and this advantage covers almost all aspects.

As soon as he walked out of the laboratory, Wu Bin felt someone pat on the shoulder, turned his head, and found that it was the big American brother who was doing the experiment next to him just now.

"incredible"

The big American brother gave Wu Bin a thumbs up, then turned and left.

"Thanks!"

After thanking him, Wu Bin happily walked forward, but was hooked by Gong Chengwei again, and said with a smile: "What are you doing, you are incredible even if the Yankees say you are."

"It's faster to do the experimental questions."

"Cowhide, cowhide." Gong Chengwei chatted back to the competition after expressing his emotions: "Although there is no electronic test, these two experimental questions today are quite interesting."

Wu Bin nodded and said, "Well, you think so too. I didn't feel very satisfied when I finished."

"Don't, don't, I'm not as perverted as you. I'm just saying it's interesting. I'll be exhausted when I'm done."

While the two were chatting, Zhang Fu also came over and complained: "Fuck me... Maozi is really insidious."

"What do you mean?" Wu Bin asked strangely.

"Damn it... I didn't notice that Maomei came to participate in the competition before. She was standing next to me just now. Let me tell you, they are really good-looking."

"Have you messed with your mind?" Gong Chengwei glanced at him and asked.

"Isn't it... I almost misremembered the data, okay?" Zhang Fu said and patted his chest, "Fortunately, I immediately recited the eight honors and eight disgraces three times before I stabilized my mind. This hairy girl is in her hands."

"Ha ha ha ha."

Wu Bin and Gong Chengwei laughed after hearing this.

Since there were only three of them in the morning session, they stopped waiting for others and went to the waiting room stipulated by the organizer.

In the evening, after all the experimental questions in the afternoon group had been tested, Wu Bin discovered that the performance of the group of big Western brothers in the past two days was quite restrained, according to their words.

"I was a little nervous before the exam, and I couldn't let it go."

As soon as the exam was over, the real high immediately came, a Maozi brother came over with two cups and hooked Wu Bin's neck from behind, saying: "Vo~~~~~dka"

Just as Wu Bin wanted to refuse, a group of candidates suddenly started booing for coming over, "OH!" "OH!" "OH!"

Seeing that Wang Gaojie was coming to help, Wu Bin waved to him, took the vodka from Brother Maozi and said in English, "I've done it, you can do whatever you want."

joke!Wu Bin is also the one who drank all night with his dad, okay? It's just vodka, fuck it!

After drinking half a glass of vodka in one gulp, Wu Bin let out a big gulp of alcohol.

It caused a burst of booing from the surrounding people.

Brother Maozi was also very happy to see Wu Bin's saving face, so he decisively drank the other glass of vodka in his hand and gave Wu Bin a thumbs up.

To put it bluntly, he mainly wanted to make friends, not persuade him to drink, so after drinking, he began to report his family name, saying that his name was Oleg, which almost made Wu Bin laugh.

A group of people are crazy, playing high all night, Wu Bin also drank a lot, hiccupped to find a few other teammates, only to find that Zhang Fu had already drunk high, standing on the grass "dance floor" with the West The big brothers twisted their bodies together.

Wu Bin didn't see the other people, and he didn't know where they went.

It wasn't until the next morning that they found out that they had played poker with a few big Nordic brothers, and won a lot of coins from them. Of course, after the game, Gong Chengwei and the others also gave a few coins of one and fifty cents to the big Nordic brothers. .

After all, their intention was not to gamble, but to play.

During the exam, the organizers arranged tours, not to mention after the exam, Wu Bin and the others were led to visit many famous scenic spots in the Netherlands, the most spectacular of which was a tulip garden, which was really beautiful. When Wu Bin arrived, he read two poems on the spot.

"Lanling fine wine tulips, jade bowl filled with amber light!"

The communication between the tour squadrons has also become more frequent, and they have learned a lot of interesting things about other countries while chatting with each other.

One day when we were visiting a fishing port at noon, a British boy named Abbott took out a toy that was new to Wu Bin and the others.

Fidget Spinner
The translation is the fidget spinner, just like the literal meaning, it is a spinning top that is played on the finger.

Abt is obviously an old hand, he can pass two fidget spinners smoothly between ten fingers at the same time.

Just when everyone wanted to try this fidget spinner, Mao Mei, who almost made Zhang Fu "break the halberd into the sand" before, came over.

Her name is Lilia, she is only a freshman in high school this year, and she is a girl who is very talented in physics, but her personality is... how should I say, unrestrained?
Lilia looked at the fidget spinner in Abbott's hand and asked, "What's the f^ucking point of playing this?"

To put it bluntly, the translation is: "What's the point of this?"

But Abt replied in a very gentlemanly manner: "I don't know! But I guess it's kinda like Sisyphus"

'What is Sisyphus? 'Although Wu Bin understood what Abbott said, he had never heard of Sisyphus.

At this moment, he suddenly missed Li Yan a little bit, because he felt that if he asked him, he would definitely know.

There was no Encyclopedia of Humanoid Figures, so Wu Bin had to turn on his mobile phone to search and found that it was a character in Greek mythology called Sisyphus.

In Greek mythology, he is the founder and king of Corinth. His strongest record is that he once kidnapped the god of death, so that there will be no more death in the world.

Then this kind of behavior offended the gods. In order to punish him, the gods asked him to push a huge boulder up to the top of the mountain. Just do it over and over again, endlessly.

The gods thought that there could be no more severe punishment than carrying out this futile and hopeless labor, and Sisyphus' life was slowly wasted in such a futile and hopeless labor.

The implication of this story is that Sisyphus' way of sharpening his thinking and fighting against fate is like the way human beings get fun and confidence from conquering nature and overcoming difficulties.There had been sympathy for his hard, almost mischievous punishment, but Sisyphus regarded it as a shame.

People who have drawn power from Sisyphus have a new interpretation of the word "suffering", freeing people from dissatisfaction and anxiety, and thus enjoying the joy of life and the joy of survival.The gloomy and decadent mental outlook has taken on a new look, and it is full of vitality.

But in today's words, the meaning of this student Abt's words should be "I don't know what it means, but I am happy to play this!"
