A certain city.
The weather was very cold. Although the snow last night was not too big, it still turned the green belts on both sides of the street into a vast expanse of whiteness, which looked quite beautiful.
It does not often snow in this city, and at most two or three times a year, once it snows, it always makes people in this city happy.
This is true for adults, and even more so for children.
On the street, occasionally there are children passing by, reaching out and grabbing a handful of snow, and playing with them without feeling cold.
A thin, tall man in his thirties, with a teenage girl, is walking down a street.
The little girl seemed to be very interested in the snow on both sides of the road. She took the hand of the tall thin man next to her and walked all the way, always staring at the snow on both sides of the road.
As she walked, the little girl tilted her head back, looked at the tall thin man beside her and asked, "Dad, why does it snow in winter?"
The lanky man smiled and replied, "Because the weather is very cold in winter, it will snow all the time."
The little girl said "Oh", turned her head and looked at the snow again. After a while, she raised her head again and asked, "Dad, why does it snow when it is cold?"
The thin man smiled and said, "Because of this because of..."
The thin and tall man's smile suddenly suffocated, because he found that he could not answer the question of his daughter.
In winter, it will snow because of cold weather. Everyone knows this, but why does it snow when it is cold?
The tall thin man thinks he should know the answer, so he just wanted to answer without hesitation.
However, when he was really going to say it, he suddenly found that he was not very clear at all.
Why do you feel that you should know the answer, but can't tell when you really want to say it?
The tall thin man thought for a while and found the reason. It seems that he doesn't actually know the answer, just because this is a very simple natural common sense, which makes him feel that he knows the answer.
In other words, he did vaguely know some concepts, but he couldn't express them accurately in words.
"Dad, why?" The thin man's thoughts had just turned, and his daughter urged him again when he saw that he hadn't answered for a long time.
"This..." The thin tall man was slightly embarrassed and anxious, he could say, "Daddy doesn't know this problem either."
But saying this will not only disappoint her daughter, but also affect his omniscient and brilliant image in her daughter's mind.
The thin and tall man doesn't want things to be like this, but he can't just say an answer to get it right.
How can this be done?
The thin and tall man was a little anxious, and subconsciously turned his head and looked around, and found that there was a bookstore tens of meters in front of him, which was quite large.
The thin and tall man's eyes lit up, and he thought of Li Fan's new book, "One Hundred Thousand Whys", a popular science enlightenment book for children, which was officially released today.
There may be the answer he needs now.
He did plan to take his daughter to the bookstore to read a book some time before, and if his daughter was interested, he would buy one.
Now, it is the right time.
So he said to the little girl: "Yanyan, about this question, dad wants you to find the answer by yourself. There is a bookstore in front of it, and there is a book in it, maybe you can find the answer you want to know."
"Really?" The little girl blinked her big eyes and said with some excitement: "Okay! Okay! Dad, let's go in quickly, I want to find the answer."
The thin and tall man breathed a sigh of relief, and finally passed the test temporarily. It is best if there are related answers in "One Hundred Thousand Whys". If not, he also has enough time to find the answers on the Internet.
The thin and tall man walked into the bookstore with his daughter, and was about to ask a staff member, where is "Hundred Thousand Whys"?
Then he didn't ask to export.
Because he had already seen "One Hundred Thousand Whys", which was placed on the most conspicuous showcase of the bookstore.
It was early at this time, and the bookstore had obviously just opened its doors for business. There were not many customers. The showcase of "Hundred Thousand Whys" was still relatively empty.
The thin and tall man took the little girl by the hand and walked to the showcase. He picked up an unpacked copy of "One Hundred Thousand Whys" on the showcase for the guests to try out, handed it to the little girl, and said, "Yanyan, that’s This book, do you find the answer in this book?"
The little girl took the book, very excited, said "OK", then opened the book, looking for the answer she wanted.
The thin and tall man looked at his daughter with a very serious look, and smiled comfortedly. He also picked up another trial book. He was also going to look for it. Is there an answer to that question in it?
If not, he can go to the Internet to find relevant answers while his daughter is reading now.
Open the book, the thin and tall man's eyes light up. The colorful patterns on the page are very interesting, vivid, and vivid, which should be very attractive to children.
However, if only these patterns are attractive to children, it is definitely not enough.
After all, this is science enlightenment readings, and those scientific knowledge should be the focus.
Otherwise, it's really the same as before, some people on the Internet worry about it, turning the cart before the horse.
And the relevant scientific knowledge, as the previous children's education experts broke the news, is in the form of question-and-answer questions.
One question, one answer, nothing else.
The thin and tall man frowned at first. He was worried that his daughter would just look at the patterns and ignore the scientific knowledge that matched the patterns.
However, looking at it, he suddenly discovered that the scientific knowledge seemed to be the main body, and the supporting patterns were only serving the corresponding scientific knowledge.
In other words, there will be no turning the cart before the horse.
What's more, scientific questions and answers that everyone thought would be very monotonous and boring before, but now when you look at them with those patterns, you will find them very interesting and attractive. One question and one answer seems to be the best form of expression.
The thin and tall man was surprised by Mr. Li Fan's work.
And at this moment, the thin and tall man suddenly heard his daughter’s surprise and excitement, "Dad, Dad, I know, I know, I know why it snows in cold weather, you see, you Look."
"Is there really an answer to that question?" The thin tall man was both surprised and ashamed.
The surprise is that the daughter really found the answer on her own.
Moreover, her daughter is so excited at this time, obviously because this is the answer she found herself.
If she told her the answer, obviously she would not be so excited.
From this point of view, "One Hundred Thousand Whys" is indeed a very good work, and it is definitely worth buying.
What was ashamed was that his daughter had found the answer in the book before him, which made him feel a little embarrassed.
Afterwards, the thin and tall man turned his head and looked at the book in his daughter's hand. On the page he was turning over, there was indeed such a problem:
"Why does it snow in winter?"
Here is the answer: In winter, the temperature is very low. When the temperature in the high-altitude clouds is below zero degrees Celsius, the water vapor in the clouds will condense into small ice crystals and small snow crystals.
On the one hand, these small ice crystals fall with the sublimation and increase in weight, and on the other hand, they follow the horizontal airflow, up-and-down airflow and turbulent flow in the clouds to move up and down.
In this way, water vapor continues to condense on the surface of the ice crystals, the ice crystals continue to grow and grow, and finally form snowflakes.
When the updraft is not enough to bear its weight, the snowflakes will fall all the way down, and when the temperature of the earth's surface is kept below zero degrees Celsius in winter, the snowflakes can fall from high in the sky to the ground. Can see it snowing.
After reading the answer, the thin and tall man couldn't help saying in his heart: "That's it."
He really didn't know the answer before, so it seems that he also needs to take a look at this "Hundred Thousand Whys".
