On March 5, 2018, Nature published two articles in a row to report on Cao Yuan, a genius teenager in China.

He made a major discovery in the field of graphene superconductivity, that is, two layers of two-dimensional graphene materials in their natural state are stacked and the twisting angle between the two layers can be controlled to build a zero-resistance superconductor with excellent performance.

Unfortunately, what Cao Yuan discovered was only low-temperature superconductivity.

1.7 Kelvin, converted to -271°C.

It is very difficult to achieve this temperature for commercial applications, and of course there is no problem with laboratory conditions.

So far, the scientific community has not achieved room temperature superconductivity.

Once room temperature superconductivity can be achieved, many devices will be revolutionized, and energy efficiency will be greatly improved.

If any scientist can be the first to achieve superconductivity at room temperature, it will be the Nobel Prize in Physics!

Chen Xu didn't think about this question for the time being.

I haven't even scratched the eight characters, and I don't even know if graphene is the best superconducting material for wireless charging, so why do you want to go so far.

The simulation program was developed, but it was so large that the laboratory computers and the network needed to be upgraded if it was to work perfectly.

Chen Xu went to order a batch of Inspur high-end servers, and Inspur Yingxin NF8560M2.

Four-way CPU, standard with two CPUs, memory 16GB, 900GB hard disk.

In the case of full configuration, it can be processed in four parallel ways, which is already quite a strong processing speed and concurrency speed.

Of course, the price is also very touching, 240,000 before the upgrade, and 420,000 after upgrading to the top of the design.

He ordered 20 units at once.

Inspur delivered the server to the door at noon that day, along with the technician who installed it.

It was a technician who was busy until 12 o'clock in the evening.

Chen Xu didn't leave, just waited in the laboratory.

After installation, load the superconductivity simulation experiment program immediately.

Then click Run

The speed is very good!

The number of simulations deduced in one second has increased from 2,000 to 1.2 million.

Chen Xu waited beside him for half an hour, and the first structural diagram was freshly released.

The photocopier over there also printed out the structure at the same time.

Chen Xu scanned the structure diagram to Xiaobai.

After confirming it, Xiaobai said: "The structure diagram is fine, you can test it." ”

"Okay, I'll check it out tomorrow. Saying that, Chen Xu turned around and walked towards the outside of the laboratory, "I'm sleepy, go to sleep." ”

Chen Xu slept in the laboratory at night.

Early the next morning, Chen Xu took 5 experimenters to the "Zhonghai Key Laboratory of Low-temperature Superconducting High-frequency Cavity" in Nanxiang District.

The laboratory was jointly funded and built in 2002 by the Zhonghai Municipal Science and Technology Commission, the Zhonghai Institute of Applied Physics and the Chinese Academy of Sciences, and was put into use in 2007.

His main research interests include superconducting high-frequency technology, low-temperature and ultra-high vacuum technology, low-temperature technology, high-frequency and low-level control, superconducting oscillator technology, etc., which coincide with his experimental direction.

After a brief communication, the laboratory happily rented a laboratory to him, including the use of cryogenic experimental equipment.

Of course, the rent and equipment usage fee will be paid separately.

After everything was arranged, the five experimenters stayed in the low-temperature superconductivity laboratory to do experiments.

When to find the best superconducting materials for wireless charging, and the equation will not leave.

……

After Chen Xu left the laboratory, he rushed to the Shangyu Mansion in the riverside area.

After a brief tidying up, he brought two sets of changes of clothes, and Chen Xu rushed to Hongqiao Airport again. On the way, I sent a voice message to Tong Lisha, telling her that she had gone to Kyoto.

Qingdao University will hold the opening ceremony of the 2019 graduate students tomorrow, and he will go over to attend.

What Chen Xu didn't expect was that Shen Yiqiu was actually in the waiting hall.

Then when I asked, I found out that the tickets of the two people were booked by Chen Yiyi, but Chen Yiyi didn't tell him that Shen Yiqiu was on the same flight as him, and even the seats were together.

Chen Xu: "I thought you were gone." ”

Shen Yiqiu: "I thought you were gone." ”

Chen Xu looked her up and down.

Although the appearance is bubbling, it is just like that after looking at it for a long time, wearing a floral dress with a ruffle collar and a shawl with long hair, she looks gentle, beautiful and generous.

"Where's your sister?"

"What's the matter with you? ”

"I forgot to ask, which university did Shen Tunan apply for?"

"Yenching University. ”

"Tut-tut~ Dragons give birth to dragons, phoenixes give birth to phoenixes, the son of a mouse can make holes, worthy of being the professor's daughter, and she was admitted to Yan University casually, which is really envious, jealous and hateful. ”

After a pause, Chen Xu followed and said, "You said that they are all compatriots of the same mother, your sister was admitted to Yan University, why did you take the entrance examination to Dong University?"

"What's the matter with you? Don't you either. ”

“…… You took gunpowder today, so angry?"

Shen Yiqiu turned his head to look at the airport outside the waiting room, with a breezy look on his face, very arrogant.

Chen Xu asked, "How do you feel about Xiaobai Translator?"

Shen Yiqiu: "I don't know. ”

"Can we still have a good conversation?"

"Can't communicate. ”

"Okay, then don't speak. ”

Chen Xu also turned around, and neither of the two looked at anyone.

Soon the ticket gate prompt sounded in the waiting hall, and the two of them walked forward one after the other.

After passing the ticket gate, enter the airplane bridge corridor and walk all the way ahead.

Shen Yiqiu brought a lot of things, and the shoulder bag on his shoulder accidentally slipped and fell to the ground, and the things inside spilled all over the ground.

There are a lot of messy things such as mobile phones, eyebrow pencils, makeup mirrors, lipsticks, keys, ID cards, driver's licenses, wallets, etc.

Two of the small pink squares are particularly eye-catching.

Passing passengers on the same plane looked at each other.

Shen Yiqiu's face turned red to the back of his ears, and he hurriedly squatted down to pick it up.

Chen Xu, who was following behind, also helped to pick it up.

Seeing that Chen Xu's hand was about to reach for the small pink square, Shen Yiqiu was anxious to grab it in front of him, but the bridge corridor was a little sloped, and she leaned forward and didn't control it well, so she fell directly to Chen Xu.

Chen Xu subconsciously stretched out his hands to block it, and then just pressed it on her chest......

"Hee-hee-hee-hee-hee......"

"Hahaha......"

Passers-by didn't see the movements of the two clearly, but they were just amused to see their embarrassed appearance.

Shen Yiqiu's face was red to the back of his ears, and he hurriedly got up from Chen Xu.

I picked up the things on the ground and put them in my bag, and ran away quickly, without even taking my backpack.

Chen Xu got up and patted the non-existent dust on his body, thinking of the moment just now, his heart rippled for a moment, and then he picked up the backpack and bag on the ground and followed.

……

At a time when countless scientific research institutions, companies, organizations and individuals around the world were shocked by Xiaobai Translator, the [Global Hacking Competition] organized by Sword and Shield also officially kicked off at the Zhonghai International Conference Center.

There are a total of 265 teams and individual representatives participating in this competition, of which 73 are foreign teams.

A total of more than 70 companies have sponsored this competition, and the sponsorship fee alone is as high as 47.5 million.

All the money will be used for the round-trip expenses of the participating teams, as well as various expenses such as food, clothing, housing and transportation during the competition.

In addition, Sword and Shield Technology also provided a high reward of 20 million in total.

The contest is divided into various forms.

There are website intrusions, database attack and defense battles, programming competitions, and software and hardware testing, etc., which is a real hacking competition.

In addition, in addition to the representatives of those companies, there were also students from major universities, and TV stations such as Dragon TV, Suzhou Satellite TV and CCTV Science and Technology Channel also reported on the opening ceremony of the game.

In the first day of the website invasion war, Baidu, Sohu, Tengxun, Sina, and NetEase, which were used as targets, were all beaten into a sieve.

The Zechariah team from Israel, with an impressive record of 21 seconds, won the whiteness website and wrote an untraceable Z on the front page......
