Scholar’s Starry Sea

"Actually, I learned that when I participated in IPhO, because of the speed of motion in the special theory of relativity, the atomic clock on the satellite will be 7 microseconds slower than the atomic clock on the ground every day. According to the general theory of relativity, the atomic clock on the satellite is 45 microseconds faster than the atomic clock on the ground. According to... People who believe in the hospital use their professional knowledge to pretend to be B.” Li Yan looked at Qin Simeng who was in a sluggish state, patted Wu Bin.

"It's okay." Qin Simeng waved his hand quickly, "I like listening to this kind of popular science."

Wu Bin tapped his forehead with his index finger, and concluded Said: "In short, after combining these two theories of relativity, it can be found that the atomic clock on GPS satellites is 38 microseconds faster than the ground every day, and because GPS relies on clock pulse signals with an interval of 20-30 nanoseconds for calculation and status. "

"If the time is not calibrated, the positioning position will begin to drift, so if there is no theory of relativity, there will be no global satellite positioning system."

After Wu Bin saw Qin Simeng who was still in a daze, he couldn't help but shook his head slightly, and gave a "perception not good" comment in his heart.

"So, do you understand what I want to express in this paragraph?"

In order to prevent Qin Simeng from continuing his "sleepwalking", Wu Bin raised a question to she.

Qin Simeng also reacted quickly to replied: "Well, I see, you are saying that the people in 1854 could not imagine that Riemannian geometry would have such a profound impact, just like today The Higgs boson."

After listening to Qin Simeng's answer, Wu Bin is still satisfied and nodded. It seems that she still listened to the content, but the performance was rather dull.

So Wu Bin went on to say: "This is the fascinating part of basic scientific research. Nowadays, how many people are behind the sentence "Can you help me find a dessert shop in Jing'an District" on their mobile phones? Is pure theory supporting?"

"Calculus, Riemannian geometry, complex functions, Probability, relativity, organic Chemistry, electricity, etc. I didn't expect that they would bring such a huge effect to today's daily life."

"Suddenly I feel so romantic." Qin Simeng gave Wu Bin a smile.

After listening to Qin Simeng’s words, Wu Bin was a little pleased and nodded with certainty and said: "Yes, science has always been very romantic. Only this can attract generations of people to look for it. The truth."

Seeing Wu Bin’s happy expression, Qin Simeng felt that he had found an entry point, so he immediately said: "Then are you interested in romantic things? For example, movies and Opera? I know there will be a Turandot next month..."

"No, I am only interested in science at the moment." Wu Bin said very seriously.

"Oh...really."

At this moment, Qin Simeng suddenly felt like he hit the wall.

But before she came back to his senses, Wu Bin had already picked up the book in his hand and waved to the two of them and said, "Then I will go back to the laboratory first. There are still many things left to do. , See you later."

"Well, goodbye." Li Yan also waved at him.

Looking at Wu Bin who quickly left the canteen, Qin Simeng sighed and fell into a deep self-doubt.

However, for Li Yan, although this kind of scene has long been commonplace, he still couldn't help but want to laugh a little.

Because he knew for the first time that Qin Xue, who was very popular and charming in the Student Union and even the entire University of Science and Technology, looked like this when she ate...

"Li Yan, have you known him for so long, can you fully understand what romance he is talking about?" The recovered Qin Simeng turned and asked Li Yan.

"Um...I think about it." Li Yan squeezed his chin and said, "Once before, someone asked the same question as you. At that time, his answer was not now This version is available."

"Russia, so there is an update to say this?"

"To be precise, there should be various versions, anyway, he can always find a direction Come let you feel the charm of science."

"Then...what did he say in that version?" Qin Simeng's expression was a little curious.

"In 200 BC, the technical house Archimedes laid the first cornerstone for fluid mechanics. Today, we go online, book airline tickets, go out, and sit on a civilian facility called airplane. Sleep for a while, and then cross the distance that Alexander's Great Emperor has not walked in his entire life."

"Wow..." Qin Simeng couldn't help opening his mouth slightly, a feeling of hard to describe suddenly rise in. the mind.

"Do you think the goose bumps are all up?" Li Yan laughed.

"Um...somewhat." Qin Simeng touched his arm.

"That's it." Li Yan shrugged, "Hey, yes, I'll ask him if he can give me the copyright of this sentence. I think it will be effective in the freshman party. It must be very good."

Qin Simeng immediately nodded and said after listening: "Good idea, how about letting him talk about it? It will be arranged behind the New Generation list."

"It seems to be good, but I don't think he has a high chance of agreeing, but I can try." Li Yan nodded.

……

"No, thank you, I just want to be a quiet audience."

Listening to the expected rejection on the other end of the phone Li Yan shrugged, "Like you, I will definitely have a lot of opportunities to speak on stage in the future, just as practice?"

"No, I am confident of my ability to perform on the spot ."

"Ai, okay, then your sentence, I will let others say it’s okay?"

"Of course it’s okay."

If there is a freshman who can feel the incomparable charm of science from his words, he will definitely feel very pleased.

"Okay, let's say so, see you later."

"Why does Li Yan want to pull you to do?" Lin Ziqi is walking with Wu Bin on the way to the library Asked curiously.

"He asked me to take the stage to give a speech to the freshmen."

"That's not good~"

"Then...you go?" Wu Bin looked at With Lin Ziqi.

"Forget it, the library is more suitable for me." Lin Ziqi finished with a trot ahead.

In the early morning of 2nd day, Wu Bin came to the gate of the Youth Home early because Gu Ningshan just returned to school yesterday, but due to jet lag, he took a break early.

Wu Bin, who was very interested in her "study abroad" experience, made an appointment with her to meet today, so he came here to wait for her proactively.

"Hey."

Not long after standing, Wu Bin's waist was pushed and turned around. It was Gu Ningshan.

"Hey, I haven't seen you for two months, don't you seem to have changed a lot?" Wu Bin said while looking at Gu Ningshan.

"I'm obviously 1 cm taller, okay! 1 cm!" Gu Ningshan raised his fingers and said very emphatically.

"Well, what is the little Gu Ningshan Senior Sister, who is 1 cm tall, going to eat today?"
