Autumn is gradually coming to an end, and the curriculum of the five junior high school students taught by Lin Ping has also come to the second year of junior high school, and the second year of junior high school will officially start physics teaching.

Physics in junior high school is relatively simple, does not require much understanding, and often only needs rote memorization to get high scores, but this can easily lead to students entering high school, physics learning because they do not form good thinking habits and interests in junior high school, which makes physics particularly difficult to learn, especially for girls.

Physics classes are about to start, and Lin Ping hopes to cultivate children's interest in physics. Even if some of them want to embark on the path of liberal arts in the future, they should still maintain their curiosity and continuous understanding of science.

And the best way to cultivate interest is to make children curious about the subject, just like the detective suspense children's novels that have been popular, such as "Adventure Tigers" and "Charles IX", as well as the Japanese cartoons "Conan" and "Doraemon", they all stimulate children's imagination to a certain extent, arouse children's curiosity, either thought-provoking or whimsy.

Lin Ping tossed and turned on the bed, what kind of things could make the students feel a deep impression and curiosity?

Schrödinger's cat? No, they certainly don't understand, it's too hard to understand.

Dark matter? They're definitely more incomprehensible.

Suspense?

Uncanny?

Science?

Unknown?

Lin Ping suddenly sat up from the bed, he thought of it! He thought of a most bizarre physics experiment, this physics experiment almost every high school student has studied in textbooks, and even physics teachers will do experiments for everyone, but the stories and problems behind this experiment have not been able to be reasonably solved in the international physics community.

Lin Ping is a man of action, when he thought of this question, he immediately got up from the bed and began to prepare the props for tomorrow's physics experiment, this experiment is very simple, but the depth of his connotation is very interesting.

On the second day, I finished speaking and counting English in the morning, and I had to teach physics in the first class in the afternoon.

Hearing about the physics class, the children were very excited, except for Liu Weiguo, the other four children were exposed to the new curriculum physics class for the first time, so they were all a little excited and novel. Although Liu Weiguo has studied, because he is the only one and Ma Zhongguo's ability is limited, it is completely by letting Liu Weiguo learn physics by self-learning and endorsement.

In addition to these five children, Lin Ping also specially called Wang Yige over to listen to the class with them.

Lin Ping stood on the podium and said, "Students, we are going to have a happy class today, are you happy?"

"Happy!"

"Have you studied the textbook?" Lin Ping asked again.

"Pre-study!"

The six students in the audience replied in unison, their tones full of anticipation.

"Haha, it's useless to prepare, today we won't talk about the knowledge in the textbook!" Lin Ping smiled slyly.

Lin Ping said: "Physics, basically can be said to be an alternative to science, we human beings can achieve today's achievements and develop today's science and technology, almost all rely on the credit of physics." Without the ever-evolving understanding of physics, we might still be slash-and-burn, we might still be riding horses and archery......"

The students listened attentively to Lin Ping's lecture on the importance of physics.

"What is physics? Your five senses, what you see, what you see, what you hear, what you hear, everything you hear, everything you touch, everything you see and touch, are closely related to physics, and the whole world is physical. Lin Ping said, "And it's not limited to this, some science fiction universes, galaxies, black holes, alien planets, parallel worlds, and time travel are inseparable from physics, even if many of them are only a theoretical existence." ”

"Physics is a very magical discipline, for hundreds of years human beings have been studying it, always trying to touch his boundaries, but whenever you want to touch the boundaries, you will find that there is a broader physical world outside this boundary, so new boundaries are born, and so on, so far human beings have not been able to touch the real limit, but our cognition is constantly deepening. Lin Ping continued, "Newton, do you know?"

"Yes!" the students replied together.

"It's the one who smashed the apple on top of his head!" Liu Xiangqian said.

"Hehe, I don't only know Newton, but I also know beef stew!" Li Shulin said with a smirk.

"Be careful, I stew you. Lin Ping said jokingly.

Then, Lin Ping continued: "Newton is very great, he discovered gravity through an apple, he is the founder of modern physics, and is known as the father of modern physics. But all his contributions to the physical sciences were made before the age of forty, so what did he do after the age of forty?"

The students shook their heads.

"He lived to be more than eighty years old, but since he was forty years old, he has basically only studied one thing - God!" Lin Ping said mysteriously.

At this time, Liu Qingmei raised her hand and said, "But, teacher, Teacher Ma has told us many times that there is no god in this world!"

"My mother believes that there is, and she offers to the Bodhisattva every day!" Liu Xiangqian said.

"My mother too, she still goes to the temple fair every day, sometimes she has to take me with her, and she forces me to kowtow to the clay figures in the temple!" Liu Weiguo said in a helpless tone, "I said that there is no god in this world, and she will beat me!"

Lin Ping smiled and nodded: "Yes, as the successor of Marxist socialism, we must firmly believe that God does not exist, we must believe in science, and your parents are a kind of traditional belief and psychological sustenance, we believe in science while respecting their beliefs, which is not in conflict." ”

"However, Newton was a great scientist, why did he study God?" Feng Xiao asked, raising his hand.

"Very simply, as I just said, our human understanding of physics is constantly deepening, and the boundaries are constantly expanding, and in Newton's time, due to the constraints of scientific research conditions and experimental equipment, he could not understand the world more deeply, and he began to study theology because of many puzzles, of course, there were also special historical conditions and historical background at that time. Lin Ping said with a smile, "And to this day, our cognition is still limited, today I want to give you a very simple physics experiment, but this experiment is very controversial, once let some scholars shake their perception and view of the world." ”

The students all pricked up their ears after hearing Lin Ping's words, and what kind of magical experiment Mr. Lin was going to do aroused their great curiosity.

Lin Ping said while starting to fiddle with the experimental equipment on the table: "Light is everywhere, the physics knowledge you should have learned now is about sound, but today's experiment is about light, it is very interesting, you should start to look at it carefully, and then listen carefully to every word I speak......"

(I wish you all a happy Chinese Valentine's Day, in order to celebrate this festival, I will add a more chapter to the single dogs of Everbright Okay!It's so late, everyone who has a girlfriend goes to KFC, and those who have wives are sleeping with their wives in their arms, just me, the single dog author is still changing the article, and you single dog readers are still reading the text, it's so pitiful, add a more, and send it out in a while.) ）
