Xueba's Sea of ​​Stars

Chapter 217 The Romance of Science

"Actually, I only found out when I participated in the IPhO, because in the special theory of relativity, due to the speed of motion, the atomic clock on the satellite will be 7 microseconds slower than the atomic clock on the ground every day, and according to the general theory of relativity, the atomic clock on the satellite will be slower than the atomic clock on the ground. Atomic clocks on the ground are 45 microseconds faster, according to..."

"You can just tell the result directly. Those who don't know think that we are using our professional knowledge to pretend to be B in front of others." Li Yan looked at Qin Simeng who had entered a sluggish state and patted Wu Bin.

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

Wu Bin tapped his forehead with his index finger after listening, and concluded: "In short, after combining the two theories of relativity, it can be found that the atomic clock on the GPS satellite will be 38 microseconds faster than the ground every day, and because the GPS relies on the interval time as 20-30 nanosecond clock pulses for calculations and status."

"If you don't calibrate the time, the positioning position will start to drift, so if there is no theory of relativity, there will be no GPS."

After finishing speaking, Wu Bin looked at Qin Simeng who was in a daze and couldn't help shaking his head slightly, and gave an evaluation of 'not understanding enough' in his heart.

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

In order to prevent Qin Simeng from continuing to "sleepwalk", Wu Bin asked her a question.

Qin Simeng also quickly reacted and replied: "Well, I understand, you want to say that the people in 1854 could not imagine that Riemannian geometry would have such a profound impact, just like Higgs Bose today son."

After listening to Qin Simeng's answer, Wu Bin nodded in satisfaction. It seems that she still listened to the content, but she just acted dumb.

So Wu Bin went on to say: "This is what fascinates people about basic scientific research. How many pure theories are there behind people saying 'Can you help me find a dessert shop in Jing'an District' on their mobile phones?"

"Calculus, Riemannian geometry, complex variable functions, probability theory, relativity, organic chemistry, electricity, etc., etc., but when each of these theories was born, I am afraid that they have no idea that they will have a great impact on today's daily life. come to such a huge effect.”

"Suddenly I feel so romantic." Qin Simeng smiled at Wu Bin.

After listening to Qin Simeng's words, Wu Bin was a little happy, nodded with certainty and said, "Yes, science has always been very romantic, and this has attracted generations of people to seek its true meaning."

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? Like movies and operas? I know there will be a Turan next month Do..."

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

"Really."

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

But before she came to her senses, Wu Bin had already waved to the two of them with the book in his hand and said, "Then I'll go back to the laboratory first, there are still many things to do, see you later."

"Well, bye." Li Yan also waved to him.

Seeing Wu Bin who left the cafeteria quickly, 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 can't help but want to laugh.

Because it was the first time he knew that this is what Qin Xue, who is very popular and charming in the student union and even the entire University of Science and Technology, looked like when she was deflated...

"Li Yan, you have known him for so long, can you fully understand what he means by romance?" Qin Simeng, who had recovered, turned and asked Li Yan.

"Hmm... let me think about it." Li Yan squeezed his chin and said, "There was a time before when someone asked almost the same question as you, and his answer was not the current version at that time."

"Oh, so there is an update for saying this?"

"To be precise, there should be various versions. Anyway, he can always find a direction to make you feel the charm of science."

"Then...what did he say in that version?" Qin Simeng looked a little curious.

"In 200 BC, Archimedes, a technology house, laid the first cornerstone for fluid mechanics. Today, we surf the Internet, book air tickets, go out, sit on a civilian facility called an airplane, sleep, and then cross Alexander the Great There is no distance that can be covered in a lifetime."

"Wow..." Qin Simeng couldn't help but open his mouth slightly, and an indescribable feeling suddenly came to his heart.

"Do you feel goose bumps?" Li Yan smiled.

"Well... a little." Qin Simeng touched his arm.

"That's it." Li Yan shrugged, "Hey, I'm going to ask him if he can give me the copyright of this sentence. I think it will be very effective for the freshman party."

After hearing this, Qin Simeng immediately nodded and said, "That's a good idea, how about letting him talk about it? Just behind the freshmen representative."

"It seems good, but I don't think the chance of him agreeing is high, but I can give it a try." Li Yan nodded.

……

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

Hearing the expected voice of refusal from the other end of the phone, Li Yan shrugged, "For someone like you, there will definitely be a lot of opportunities to speak on stage in the future, so just use it as practice?"

"No, I'm confident in my ability to perform on the spot."

"Oh, that's fine, then, it's okay for me to let others say what you said?"

"No problem at all."

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

"Okay, that's all for now, see you later."

"What does Li Yan want to drag you to?" Lin Ziqi, who was walking with Wu Bin on the way to the library, asked curiously.

"He put me up on stage to speak to freshmen."

"That's not very good~"

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

"Forget it, the library is more suitable for me." After Lin Ziqi finished speaking, she jogged ahead.

In the early morning of the next day, Wu Bin came to the gate of the Youth Court early, because Gu Ningshan had just returned to school yesterday, but because of jet lag, she had a rest early.

And Wu Bin, who is very interested in her experience of "studying abroad", made an appointment with her today, so he took the initiative to come here and wait for her.

"Hey."

After standing for a long time, Wu Bin's waist was pushed, and when he turned around, it was Gu Ningshan.

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

"I've obviously grown by 1 centimeter, okay! 1 centimeter!" Gu Ningshan raised her fingers and said emphatically.

"Okay, what does Miss Gu Ningshan, who has grown by 1 centimeter, plan to eat today?"
