Huo Qinian moved to Su Yunbai's house. He had never lived in such a "cramped" house since he was a child, even when he was studying abroad, but this time, he lived in a surprisingly comfortable house and felt that everything was perfect.
He put all his attention on the flowers and plants in the courtyard, almost empathizing with them. When he missed her, when he couldn't sleep, when he felt guilty... At any time, as long as it was related to Su Yunbai, he would either weed and kill insects, or water and fertilize, or trim branches and leaves...
In just one week, more than half of the flowers and plants in Su Yunbai's courtyard were killed or injured by him.
Huo Qinian's expression was as if the sky had fallen: Su Yunbai's flowers and plants were all affected by her temper, and they didn't like him at all?
Although Huo Qinian couldn't help thinking so, he didn't believe in superstition and couldn't help but find someone to take a look privately.
After the flower farmer finished checking, he was not polite and scolded him.
Is there anyone who takes care of flowers and plants like this? Either they will die, or they will be burned to death by adding too much fertilizer. He was too considerate to add a cover for the sun-loving plants, and he thought that they needed some sunshine for the shade-loving plants. Not only that, he also trimmed and cut branches and leaves randomly for no reason... He is
so capable, why doesn't he go to heaven?
Huo Qinian sent the flower farmer away, and facing the flowers and plants in the courtyard, he felt that he was stupid.
He simply couldn't believe that he would make such a stupid mistake. Flowers and plants have their own habits. How can he expect them to grow well just because he treats them according to his preferences?
If flowers and plants are like this, how much more so people?
When Huo Qinian thought of this, he didn't care about why he was so stupid. He just felt very empty in his heart.
This kind of short-term, self-deceiving empathy can no longer work.
What if the garden is full of green plants? In the end, the person who returns will never come.
Huo Qinian has developed the habit of reading Weibo, especially Xu Jinzhi's Weibo account.
If there is anyone in the world who can share news about Su Yunbai, it can only be Xu Jinzhi.
But the frequency of her sharing news about Su Yunbai is too low, and it is all useless information.
Huo Qinian once again read a series of Weibo posts forwarded by Xu Jinzhi with the caption "Hahahaha", but he couldn't understand the funny part at all, and couldn't help rubbing his eyebrows.
He began to wonder if his "waiting for the rabbit by the tree" was a futile effort - did he wait for the wrong "tree"?
But Xu Jinzhi soon proved to him that his choice was indeed correct.
Before going to bed that night, Huo Qinian once again checked Xu Jinzhi's Weibo as usual, and suddenly saw a new message she forwarded.
This was a message with a label, and the label name was "Romance unique to science and engineering students." After Xu Jinzhi forwarded it, she also added her own comment: "Oh, I actually saw last year's teaching assistant on the hot search! The teaching assistant is so good! [Starry eyes.jpg][Drool.jpg]"
Xu Jinzhi only knows how to ask one person to be a teaching assistant.
Huo Qinian was refreshed by what he saw.
He clicked on the message forwarded by Xu Jinzhi: [#Romance unique to science and engineering students# It seems that it is time to present the video I have collected for a long time! Reinterpreting "The more you return from a long journey, the younger you look", "Life lies in exercise" and "Time was slow in the past"! Wuwuwu Teacher Su, my goddess!! Goddess!! [Broken voice][Video link]】
Teacher Su? !
Huo Qinian's heartbeat quickened.
His hands were faster than his brain, and he immediately clicked on the video link.
The video was a bit long, and after the buffer time, what appeared on Huo Qinian's mobile phone screen was Su Yunbai's appearance.
She was wearing an off-white knitted sweater with her sleeves slightly rolled up. She held a piece of chalk in one hand and gestured something with the other hand.
The lights in the classroom were bright. She was standing on the podium, facing the camera sideways, with bright eyes and a hint of smile on her face, and her profile looked extremely gentle.
They hadn't seen each other for two months, but it felt like they had met again after many years.
Huo Qinian was distracted for a moment and almost didn't hear what she was saying.
After a long while, Su Yunbai's voice finally reached his ears -
"The narrow relativity effect is a relatively abstract theory. Two very famous conclusions can be derived from its formula, which are what we often call 'shortening of moving rulers' and 'slowing down of moving clocks'.
"I have written the formula on the blackboard. We derived it step by step in the last class. Do you students still remember it?"
There were responses one after another in the background.
Su Yunbai smiled, "I really remember it. You didn't lie to me, did you? "
Her mood was obviously very good," Just remember it. Let's look at these two formulas and briefly go over the two conclusions.
"What is 'shortening of the moving scale'? It means that if the relativistic effect is taken into account - this means that the speed of the object's movement must be very large, so large that it can even be compared with the speed of light. At this time, the v/c in the formula has numerical significance.
"In this case, the concept of length will change. That is to say, the length L we measure at this time will be shorter than its true static length l.
"Please note that this does not mean that the actual length l of the object has changed, but that when we measure this high-speed moving object in a static reference frame, we will feel that the length of this object has shortened.
"This is 'shortening of the moving scale', and what is shortened is the measured quantity L.
"'A moving clock slows down' is the same principle. The time T experienced by a moving object is shorter than the time t we feel when it is still. In other words, time moves slower for a moving object."
Su Yunbai paused when she spoke here.
The smile on her face became wider, "Speaking of this, I suddenly remembered something interesting. Have you ever heard of a line of poetry, 'After traveling thousands of miles, I look younger' by Su Shi?
" "Hear it? No? It seems that some people have heard it and some have not. It doesn't matter. The second half of the sentence is more famous, and you should all know it - 'Wherever my heart is at peace is my hometown'?
" "I see that everyone nodded, so it seems that everyone has heard this line.
"'After traveling thousands of miles, I look younger' and this line are from the same poem, both by Su Shi.
"It means, after coming back from a very long distance, one looks younger... Strictly speaking, one looks younger, but here we are speaking in a general way, only saying very young. After all, time cannot go backwards, and from a numerical point of view, there is no such thing as 'younger'.
"We don't consider anything else, but only explain this phrase from a physical point of view. How can we achieve 'looking younger after a long journey'?"
Su Yunbai had a sly smile, and her whole person exuded a special sense of liveliness.
She used the chalk in her hand to point to the second formula on the blackboard, "Here, the moving clock slows down. I stand still and my time is t, while you are moving at high speed, and your time is T. The moving clock slows down, and T is smaller than t. Your time passes more slowly, and you look younger. So 'the more you travel, the younger you look.'
"Of course, the concept of 'relative' is also involved here. One of the famous problems is 'twin feints', which is the focus of our discussion in this class..." There
were exclamations in the background. Seeing
that they were interested, Su Yunbai said a few more off-topic remarks, "So even if you study science and engineering, don't lose your ability to associate romantically. Think more and ponder more in life, many things are actually very interesting.
"For example, 'life lies in movement'. How can this be explained by the conclusion of 'moving clocks slow down'?
"It's very simple. When you move, doesn't your time slow down? Although your speed is too slow and there is almost no relativistic effect, you are moving at least, right?
"When you move, time slows down. Compared with those who don't move, don't you look younger? If everyone's life span is the same, your time passes slowly, then don't you live longer?
"Of course, I exaggerated a little here. Because the speed of our movement is so small compared to the speed of light, v/c is almost directly equal to 0, and the difference caused by acceleration and deceleration can be almost ignored. I am just saying this here, do you understand?
"But this does not mean that this statement itself is wrong. Exercise regularly and you will be healthy. A healthy body will lead to a long life. This actually makes sense."
The students were very excited and obviously felt that this statement was very refreshing.
Su Yunbai waited until they were almost excited before saying, "Interesting, right? So it is important to learn physics well. Of course, people who study physics can also read more poems and songs. The next time someone wants to talk to you about love and romance, won't you have something to say?
"When others complain that you don't understand romance, you can also tell them what the world is like in the eyes of science and engineering students..."
"Don't say I'm exaggerating. This skill is very helpful in solving lifelong problems."
The students howled.
Obviously, everyone understood what was said.
Some students even spoke up boldly: "Teacher, one more!"
Others followed suit: "One more!"
"We want to hear 'Solving the most important issues in life'!"
In the noisy atmosphere, the smile on Su Yunbai's face on the stage paused slightly, and then quickly returned to normal.
She leaned on the edge of the podium, "One more is fine, but I have told you stories in this class, how do I know how much of the key points of this class you have mastered?
"How about this, I will give you a small test on this class at this time next week, do you agree?"
"Yes!"
"Teacher, please tell me!"
Su Yunbai smiled, "Okay, then I will tell you another one. This is not my original creation, but something I heard. It may be more targeted, targeting the part about 'solving life's major issues.'"
Amid the howling of the crowd, Su Yunbai continued: "Have you heard of a poem by Mu Xin? It's called "The Past Was Slow."
"'The days used to go by slowly. Cars, horses, and mail were all slow. A lifetime is only enough to love one person'..."
Her voice lowered and became extremely gentle, as if she was reciting a love poem to someone, and every word and sentence was her unspeakable thoughts.
Huo Qinian looked at Su Yunbai like this, and
he couldn't help but feel his heartbeat quicken. "The Past Was Slow"... He knew it too well!
He used to have a foreign friend who used this poem to pursue a Chinese girl.
He was obviously used to hearing this poem, and even his ears were almost entangled with it, but why did the same words coming out of Su Yunbai's mouth have their own magic, making his heart beat out of control?
Huo Qinian looked at Su Yunbai, not willing to blink.
The smile on Su Yunbai's face somehow became lighter.
She said: "The explanation of this statement that I heard is on the large scale of the universe.
"We all know that the scale of the universe is very large, so large that even the speed of light takes a very long time to travel. On such a scale, it is possible that the light from some stars that we receive has exhausted our lifetime.
"Light can be used to transmit information. The speed of light is actually very slow compared to the scale of the universe, and therefore the information is transmitted slowly, so we say, 'It is enough to love only one person in a lifetime'..."
Huo Qinian looked a little confused.
These words... why do they sound familiar?
He frowned and thought carefully. Suddenly, an idea flashed in his mind, and he was struck by lightning.
He couldn't help but sit up straight.
He remembered!
"The Slow Time"...
On the grand scale of the universe, there is only one person you can love in your lifetime...
He once "explained" "The Slow Time" to someone like this!
It was her!
The girl who watched the comet with her that night was her!
It turned out that they had known each other for a long time.
The video had already ended, but Huo Qinian stared at the screen blankly for a long time without coming back to his senses.
He felt dizzy and his heartbeat was unbearably fast.
Many things cannot be thought about too much. The more you think about it, the more you feel a sense of fate. There is
only one person you can love in your lifetime... This is growing old together.
It was the first time he recited a poem about growing old together with someone. And this person later became his wife, and now he has become his obsession.
There were so many students at the observatory that night, but she was the only one who bumped into him, he was the only one who started chatting with her, and she was the only one who gave him a reason to assemble a lens to watch the comet.
The world is so big, and the population of China and the United States combined is so large... They first met at an observatory in a school in the United States, and then two years later, they officially met in a university in China, and then got married.
From China to the United States, 2 in 1.7 billion.
If this is not fate, this is not destiny, then what is?
He should not deceive himself anymore.
He has never forgotten her, and he doesn't want to forget her.
He can't let go, and his heart is always itching to do it.
She said she didn't love him anymore, she said her feelings were expired, she said he was no longer her white moonlight...
It doesn't matter.
In the past relationship and marriage, she gave more than him. This time, it's his turn to love her.
It's her turn to be his white moonlight.
So what if she is in the United States?
Love can make mountains and seas flat!
He decided, he wants to go to the United States!
