Into Unscientific

in real life.

Speaking of the seven words "School of Physics, University of Science and Technology of China".

Key words such as classical physics, quantum physics, academician Pan, and Lu Chaoyang may pop up in the minds of most people.

But few people know.

The School of Physics of HKUST covers an extremely wide range, even including a very, very unpopular department.

According to the division of teaching and research functions, the School of Physics of HKUST has five departments.

At the top of the list is naturally the Department of Physics.

The Department of Physics is divided into three directions:

condensed matter physics,

biophysics,

Microelectronics.

Then there is the Department of Modern Physics, which has five directions:

theoretical physics,

particle physics and nuclear physics,

atomic and molecular physics,

physical electronics,

spin physics.

Among them, the accelerator that Zhao Zhengguo is in charge of belongs to particle physics and nuclear physics, which is also the department that Xu Yun went to after changing his major in his previous life.

Then there is the Department of Optics and Optical Engineering, and the Department of Engineering and Applied Physics.

In addition to the above four departments.

HKUST also has a department, that is.

Department of Astronomy.

This is actually an unpopular profession.

Before 1998.

For a long time in China, only three schools, Nantah University, Peking University, and Beijing Normal University, have astronomy courses.

In 1998.

HKUST officially established the Department of Astronomy and Applied Physics, making it the fourth school in China to have an astronomy department.

But even so, there are only 20 to 30 students in the astronomy department of HKUST every year.

And there are about 20 teachers.

Xu Yun once heard some unlucky guy who accidentally entered the astronomy department complain. Every time there is an event in the astronomy department, there is almost always a teacher sitting opposite him, which looks like a blind date.

Of course.

There are also benefits to this ratio.

That is, when undergraduates do scientific research, they will also be supervised by tutors, and undergraduates can apply for funding.

The undergraduate funding of the Department of Astronomy of HKUST is generally 20,000 RMB, with a cycle of one year, supporting various consumables, books, travel and so on.

There is also a more unpopular knowledge.

That is, HKUST not only has an astronomy department, but also an observatory.

This observatory is the Key Laboratory of Galaxy and Cosmology of the Chinese Academy of Sciences located at the headquarters of the University of Science and Technology of China. The name is a bit awkward to read.

In October 2005.

The Modu Astronomical Observatory of the Chinese Academy of Sciences and the University of Science and Technology of China established the "Joint Laboratory of Galaxies and Cosmology".

December 2008.

The Chinese Academy of Sciences officially approved the establishment of the Key Laboratory of Galaxy and Cosmology of the Chinese Academy of Sciences.

The key laboratory is further divided into the Department of Modu Astronomical Observatory of the Chinese Academy of Sciences and the Department of the University of Science and Technology, which are respectively in charge of the Astrophysics Laboratory of the Modu Observatory and the Department of Astronomy of the School of Physics of the University of Science and Technology of China.

In HKUST.

The astronomy department and observatory of HKUST are so unpopular that even many HKUST students do not know that there is such a major and laboratory in their school.

even in a strict period.

A student from the astronomy department showed his student card and wanted to enter the school, but was suspected of being a forged student card. The security guard swore that there is no astronomy department in our school

But just today.

The Galactic Cosmology Laboratory, which was originally deserted and deserted, ushered in a group of new guests who were looking into their brains.

In the southern part of the East District of the University of Science and Technology of China, in a building that looks very low-key on the outside.

"Wow, this is our school's Galaxy Cosmology Laboratory?"

Looking at the surrounding silver-white smooth walls and the glass curtain wall simulating the starry sky overhead.

A girl with a single ponytail and a very delicate appearance couldn't help but exclaimed:

"It's so beautiful. It's the first time I know that our University of Science and Technology has such a laboratory."

"."

A young man with literary long hair standing next to the girl heard the words, the muscles on his face couldn't help but twitched slightly:

"Actually, this classmate, during the Super Blue Moon in 2018, our lab also disclosed it to the public. At that time, more than a thousand people came."

Looking at this young man who was trying to emphasize the existence of the astronomy department, Xu Yun on the other side couldn't help but patted him on the shoulder:

"Old Zhang, give up, your astronomy department is a little transparent from top to bottom, there is no way to save it."

Convex.

The long-haired literary and artistic young man raised two middle fingers towards Xu Yun, contrary to his style of painting, and sent a cordial greeting:

"Xu Yun, your uncle!"

Xu Yun suddenly burst out laughing.

This seemingly literary young man is called Zhang Heguang, who is the same age as Xu Yun, and is currently studying for a Ph.D. in astrophysics at HKUST.

Well, 24 years old, a graduate student.

Both he and Xu Yun were classmates in the junior class of the University of Science and Technology, and they lived in the same dormitory at the beginning, and Xu Yun was often tortured by his snoring.

It's just that Zhang Heguang first studied theoretical physics, and later switched to astrophysics.

From the time they entered school until now, the two have known each other for several years, and their relationship has always been pretty good.

Just because of the professional direction, after the establishment of the company, Xu Yun never found a chance to call Zhang Heguang to help.

not long ago.

After noticing that the atmosphere of the members of the group was a bit depressed, Xu Yun contacted Zhang Heguang, hoping to come to the Galaxy Cosmology Laboratory to see the stars.

Zhang Heguang naturally raised his hand to welcome this.

"Everyone should be able to notice that although the walls on our floor are smooth, their surfaces have undulations."

In the laboratory, Zhang Heguang was leading the way while acting as a tour guide:

"This is actually a bottom-up curved tube-shaped structure to express the concept of space-time curvature in Einstein's general theory of relativity."

"As for the spherical glass wall on the other side, it refers to a three-dimensional surface with a smooth transition, and the visual effect is still very impactful."

Then Zhang Heguang stopped and pointed forward:

"And that's it. You see."

Everyone followed Zhang Heguang's direction.

Only at this moment.

There was a disc on the ground not far from them, and a small iron ball was slowly swinging on the disc.

This device is no stranger to Xu Yun, who is engaged in physics research, and it is the famous Foucault pendulum.

This is a very primitive device that can verify the rotation of the earth.

Whether it is conventional physics or astrophysics recognized by ordinary people, it has a very special position.

Of course.

The Foucault pendulum in reality cannot really swing by itself due to air resistance—for example, the Foucault pendulum in Yanjing Science and Technology Museum requires staff to manually start it three times a day.

Then soon.

Zhang Heguang led everyone to the second floor.

The painting style on the second floor of the laboratory is still all silver and white walls, giving people a quiet, clean and high-tech feeling.

However, different from the layout on the first floor, the ceiling in the center of the second floor is no longer covered with a glass curtain, but a huge gray hemisphere is hung.

From a distance, it seems that it has fallen from a higher level.

Xu Yun didn't know Zhang Heguang in his previous life, so this was actually his first visit to the Galaxy Cosmology Laboratory, so he couldn't help asking:

"Old Zhang, what is that ball?"

"Oh, you said that hemisphere."

Zhang Heguang pointed to a certain corner, where there were several sofas with special looks:

"It's called Dynamic Luminous Earth, and it's still being assembled. It can simulate the entire Earth, that is, the real-time starry sky around the world, with high precision."

"After it is put into use, just lie on those lazy sofas, and then select the area you want to see, and you can look at the stars like lying on the prairie."

Xu Yun nodded thoughtfully.

This is quite an interesting device, basically you can watch wherever you want?

This mode is somewhat similar to remote live broadcast on the Internet, that is, a camera in a certain place opens a soft bgm, and broadcasts real-time car conditions, pedestrians or some outdoor scenery to other viewers who cannot come.

However, the audience of this kind of equipment obviously cannot be people like Zhang Heguang who can watch the stars every day. In other words, the Galaxy Cosmology Laboratory seems to be ready to open to the outside world?

Then Zhang Heguang took everyone to visit some other modules, and finally arrived at

Outside an observation deck.

The base of the observatory is a very standard circle with a diameter of about five or six meters and a height of about half a meter. It is divided into several steps for people to walk on.

An astronomical telescope is placed in the center of the base, which is about 400 mm in diameter.

"Actually, because of the light pollution in Luzhou, the urban area is not suitable for observation."

side of the observatory.

Zhang Heguang duangduangduang patted the handrail and explained to everyone:

"The most suitable stargazing spots in Luzhou are Dashu Mountain and Zipeng Mountain, where you can see many beautiful and peculiar astrological phenomena."

"However, tonight's conditions are good. Everyone came here mainly to relax. I discussed with Lao Xu and observed directly in the school."

"Our laboratory has a 430mm main astronomical telescope, a 60mm wave telescope, and other equipment that can be disassembled and moved."

"This telescope has almost been adjusted, who wants to try it first?"

"Me, me, me!"

Zhang Han quickly raised her hand. This female doctor has a very active personality, and after getting acquainted with everyone, she has a somewhat social attitude:

"Dr. Zhang, where is Leo? I'm a standard Leo."

Zhang Heguang smiled and nodded:

"Leo, right, no problem!"

For a person like him who has been bored in the observatory for a long time, the more lively the guests, the better - as long as they don't make trouble for no reason.

Then he stepped forward to adjust the telescope data familiarly, and clapped his hands neatly after a few minutes:

"It's done, the brightest one is Xuanyuan Fourteen, the main star of Leo."

Zhang Han hastily walked to the side of the telescope, brushed back his long hair that had blocked his vision, and lowered his head to look.

A few seconds passed.

Zhang Han's voice suddenly raised a bit, but his eyes were not willing to leave the telescope at all:

"I saw it, it's so beautiful, Xiaoye, come here!"

Seeing this, a group of people gathered around one after another, and various voices rang out:

"Let me be healthy!"

"Can you see Namek?"

"It's so beautiful"

"Dr. Zhang, adjust this knob first, oh oh, I understand. By the way, is the imaging of the astronomical telescope positive or negative?"

A few minutes later.

Zhang Heguang quietly withdrew from the crowd after teaching them the general steps, and handed over the scene to Zhang Han and others.

Then he went straight to Xu Yun's side, smiled and hammered Xu Yun's shoulder:

"Okay, old Xu, I haven't seen you for a while, and I'm the big boss and I'm leading the project team again, when can I get a Nobel Prize to open my buddy's eyes?"

"roll!"

Xu Yun kindly returned the guy with a middle finger, and then pointed his chin towards the astronomical telescope:

"By the way, Lao Zhang, if you're not watching them, aren't you afraid they'll damage the telescope?"

Zhang Heguang sneered, with an expression of 'you are too young':

"Old Xu, you don't understand now."

"The possibility of man-made sabotage was considered at the beginning of the design of this thing, and all the key parts are as hard as the armor of a tank—here, just the mirror surface of the star finder, you can't break it with a hammer, okay? "

"As far as the people you bring, even if you let them get started, they can at most tear off the leather of the seat."

Xu Yun was taken aback for a moment, and when he recovered, he felt as if

Really?

Adding protective measures to public instruments is also a technology, or a measure, that has gradually become popular in recent years.

For example, science and technology museums are set up in many places in China, and their main function is to popularize science and technology knowledge for young people.

In order to prevent some brats in the target group from making troubles, some equipment will use many rather solid protective measures.

For example, the astronomical telescope in the Shanghai Science and Technology Museum uses tank armor and bulletproof glass, and it is tens of thousands of square meters in size.

But what is even more outrageous is not this matter, but that there are really bears who smashed the glass with a fire extinguisher

Then Xu Yun glanced at the crowd around the telescope, and an inexplicable brilliance flashed in his eyes.

He coughed lightly, and said to Zhang Heguang seemingly casually:

"Old Zhang, by the way, what have you been doing recently?"
