"Did your father ask you to come?" I squatted in front of Li Xiu and asked.
At that time, Yuan Hai was instructing a group of people who didn¡¯t look like a moving company to move our luggage. My mother was afraid that something would be missed, so she walked around to remind others. My dad's several large boxes of books were the most important things. He carried them downstairs with his hands behind his back, for fear of making any mistakes.
Li Zhurong stood at the corner of the corridor upstairs and made a phone call.
Li Xiu was sitting on the stairs, still carrying his backpack, looking innocent.
"I came here myself."
I glanced at the door and found that no one was looking here: "Isn't it Yuan Hai's suggestion?"
"no."
My mother ordered people to move a few small tile jars - they were used for making sauerkraut.
"Mom, don't take this thing with you. Give it away." I turned around and advised my mother: "How can I bring this thing with me?"
"You have to take it with you. This pickled cabbage will be expensive in Beijing. I've given away a few jars. I'll keep these two jars for myself."
I am speechless for her.
¡°You don¡¯t need to bring so many clothes. Whatever quilts you bring, it¡¯s not like you can¡¯t buy quilts in Beijing.¡±
"You won't wear clothes or cover yourself with a quilt when you get to Beijing?" My mother taught me: "Where can I buy new ones and it will cost money"
"Take it with you, take it with you. It will depend on how you get on the train. You have to take Li Zhurong's plane."
"It's okay. You can bring everything with you. There is room for the teacher to put it." After Li Zhurong finished the phone call, he stood on the stairs with evil intentions to encourage my mother, his eyes were crooked in laughter.
Because of Li Xiu¡¯s incident, my mother was still a little resentful of Li Xiu, but she had no choice but to ignore him and responded with a confident ¡°hmm¡±.
When everything was finally ready and ready to go, Yuan Hai skillfully directed the "movers" who looked like factory workers: "Drive to the airport and use my name card to get in."
I sat on the sofa in Li Zhurong's car and explained to my mother: "There are so many things that can't be taken on the train. They can only be taken by plane. Why don't you throw some away?"
My dad is sulking.
My mother finally realized that she had indeed brought too much, but refused to admit it: "I have already given away a lot of things, and these are what I need to bring"
She didn¡¯t say that my dad was okay. As soon as she spoke, my dad got upset: ¡°What are you bringing with you for those sauerkraut? Whoever eats your sauerkraut won¡¯t be able to get on the train now!¡±
¡°I don¡¯t even read those big boxes of books of yours, why don¡¯t you just throw them at home.¡± My mother argued with him.
My dad was blocked back and leaned to the side silently, his face turned red with anger.
At this awkward moment, Li Xiu put on an expression that he would never show normally - I bet he was imitating Lu Jiaming. He crawled from one end of the sofa to the other, found a book I was reading, and asked loudly Me: ¡°What is a brief history of time?¡±
You seemed to have told me last time that Hawking¡¯s book was written for primary school students, right?
I was afraid that no one would answer him, so I had to cooperate and tell him: "It's a physics book."
"Is it about the universe?"
"Yes."
"Uh, what is a vacuum?"
"Vacuum, in a physical concept, refers to a space without any matter, just like a box with nothing inside, not even air. Outer space is the closest to a vacuum"
"Why is it the closest? If we take a bottle and take out all the air inside, wouldn't it be a vacuum?" Li Xiu continued to ask persistently.
My dad interjected calmly: "A man did the same thing in 1654, but what he got was not a vacuum. Even if you took away all the air, there would still be particles constantly being created and destroyed. In outer space The reason why vacuum is said to be close to vacuum is that it is not always equal to 0, but sometimes is in a state of 1+(-1)=0."
As expected, I am a physics teacher, and such a question can be answered so simply.
"Is it impossible to propagate sound in a vacuum?" Li Xiu asked seriously.
"Yes. Vacuum does not conduct heat and cannot transmit sound, but it can transmit light."
¡°Is it true that a real vacuum cannot transmit sound, or is it that the vacuum in outer space cannot transmit sound?¡± Li Xiu was asking the truth.
¡°A real vacuum cannot propagate sound, and neither can outer space.¡± My dad has infinite patience in physics.
Li Xiu frowned: "Sound is transmitted through matter. You said that there are particles in outer space. If there are particles, vibrations can be transmitted."?.
¡°It¡¯s okay, he¡¯s seen a lot of beautiful people.¡± I comforted my mother.
"You are still young and don't understand." My mother said, "Men like new things. It would be great if you find someone like your dad and we can study together. You are good-looking, good-tempered, and well-educated." Gao, it¡¯s not like he can¡¯t be found, why do you want to hang out with him?¡±
At this point, all I have to do is listen.
"And that little kid is not a fuel-efficient lamp either. His blue eyes are so bright that it's scary. Just wait and see, there will be stories like this. When he grows up, he no longer recognizes you, treats you badly, and suffers a lot. you eat¡¡"
My father coughed slightly to express his disapproval of my mother's evaluation.
