Hu Xuefei said: "So, Teacher Lin may be a liar, he doesn't know how to teach at all?"
"Oh, look at his clothes, he looks a bit like a teacher. I guess he must have stolen things before!"
"That's right. Otherwise, why were our mobile phones stolen yesterday without anyone noticing?"
Lin Haochuan walked into the classroom carrying a black briefcase. The students suddenly became quiet, and the whole classroom was silent.
"Okay, today I'll choose a chemistry class representative. It's just you, Li Zixing. Come over and hand out textbooks to me!"
"Huh? Call me?"
A conspiracy, it must be a conspiracy.
I wanted to kill him twice? He actually asked me to be his chemistry class representative?
You want to torture me, right?
When those two S-class killers arrive, I want you to look good!
Li Zixing came to Lin Haochuan with proud steps.
Lin Haochuan raised his head, stared into Li Zixing's blue eyes, and said, "What's wrong? Is there any problem?"
Li Zixing: "No, I will do it if you want me to!"
Liu Chicheng in the audience was stunned for a moment and sweated for Li Zixing.
This teacher is a devilish teacher, it’s best not to mess with him!
"Okay, you can hand out textbooks to me now. We don't have much time. I will teach you some knowledge this morning and start doing chemistry experiments at noon!"
Then, Lin Haochuan asked Li Zixing to distribute all the textbooks he had written to the students one by one.
There are a total of thirty-nine students in Class Two of Senior High School. Lin Haochuan has printed forty textbooks. Dong Yiran just took a copy, so he can just distribute them all.
Of course, there is also an original manuscript, which Lin Haochuan left for himself to use in class.
"It's strange, why is this year's chemistry book in black and white?"
"That's right, it doesn't even have a cover? And what kind of nonsense is written inside? It has nothing to do with the courses we learned last semester!"
"Damn, my tuition fee is 100,000 yuan a year, and this school will give us a book like this?"
The students in the audience were indignant. Lin Haochuan raised the corners of his mouth slightly and ignored their complaints.
"Teacher, could you have picked up the wrong book? Our chemistry books for senior high school students are not like this!"
Liu Chicheng covered the textbook, pointed at the book and said, "Teacher Lin, look, there isn't even a cover!"
"Oh, I'm sorry. This is the book I made for you last night. I didn't have time to make a cover. There is some key knowledge in it, which I wrote down with a red ink pen. Please take note of it!"
After Lin Haochuan finished speaking, all the students under the podium were shocked.
Even Li Zixing stared at Lin Haochuan with disbelief.
"How is this possible? Teacher, is this a book you wrote? And it's a chemistry book written in one night?" Liu Chicheng said.
Lin Haochuan said: "Yes, is there any problem?"
"No, no problem, but teacher, your handwriting is so beautiful. If you hadn't said it yourself, I would have thought it was printed!"
"Haha, this is lower case, it's easier for you to read!"
Lin Haochuan smiled. The textbook was not the time for him to show off his calligraphy.
If it is written in wild cursive fonts or oracle bone script, I am afraid that none of the students here will be able to understand it.
"Okay, without further ado, let's start the first lesson today, let's learn about light atomic nuclei and heavy atomic nuclei!"
After speaking, Lin Haochuan wrote a few big words on the blackboard.
He still used small regular script and looked extremely upright.
But none of the students in the audience were interested in appreciating Lin Haochuan's calligraphy.
Instead, he focused all his attention on the big words on the blackboard.
"Light atomic nuclei and heavy atomic nuclei? Teacher, we didn't learn these at all last semester!"
Liu Chicheng, who was at the second table in the third row, raised his hands.
Lin Haochuan said: "Oh, it doesn't matter much. I didn't learn it last semester. Isn't this class teaching you?"
"Okay, students, today we will start the first lesson, learning about light atomic nuclei and heavy atomic nuclei!"
"Teacher, may I ask, what do light atomic nuclei and heavy atomic nuclei mean?"
Liu Chicheng raised his hand and asked.
Lin Haochuan said: "To put it simply, this is the basic reaction of nuclear fusion and nuclear fission. Everyone, please turn to the first page of the textbook and let me explain it to you!"
What? The whole class was stunned.
Even Li Zixing, who originally disdained to listen, widened his eyes.
What does this teacher do?
In the first chemistry class of school, he taught everyone about atomic nuclei and nuclear fusion?
Is there any mistake?
"Ahem, the truth is actually very simple. Nuclear fusion refers to the generation of neutrons and helium-4 by atoms with very small mass through high temperature or under certain conditions. The resulting ability is called nuclear fusion..."
Lin Haochuan's voice was continuous on the podium, saliva flew everywhere, and he became more and more energetic as he spoke.
The students in the audience looked confused when they heard this.
The reason why Lin Haochuan can speak so fluently is because he has taught Einstein and Tesla before.
These two students can be said to be the two most outstanding students taught by Lin Haochuan!
"Compared to nuclear fission, the radiation hazards of nuclear fusion are much smaller. Moreover, the atomic bombs, hydrogen bombs and other nuclear bombs that are well known to students are all based on nuclear fission reactions, so they will cause huge radiation hazards and leaks!"
"Gudong..."
Liu Chicheng swallowed a mouthful of saliva. The more he listened, the more mysterious and creepy he felt.
"The atomic nucleus is small in size but large in mass. Although the atomic nucleus only occupies one hundred billionth of the volume of an atom, its mass accounts for more than 96% of the entire atom, and its nuclear density is about
is 10^17kg/m. This is why, once nuclear fusion or nuclear fission occurs in the nucleus, it can bring about huge energy reactions..."
