Mathematics and physics are inseparable.

Among all disciplines, mathematics and physics are the closest link. Other chemistry and biology subjects can be without mathematics, but physics cannot be without mathematics. Many academic masters are both masters of mathematics and physics.

Li Xuan has no prejudice against physics. After listening to Liang Zhihui's words, he felt very strange: "Why do you say so?"

Liang Zhihui smiled and said: "In physics, the Big Bang in the Universe is extremely large in 13.8 billion years, but in mathematics, it is common. 2 is 31 digits to the power of 100, and it will explode casually, not on the same order of magnitude. The current theory of physics may be overturned in a few years, and high school physics may be wrong, but the knowledge passed down by mathematics that has been learned for thousands of years is almost impossible to overturn. Can 1+1 not equal to 2?"

Li Xuan was stunned and found out that Liang Zhihui looked down on physics for the first time.

There is a chain of contempt in subject competitions, mathematics despises physics, physics despises chemistry, and chemistry despises biology. At the top of the chain of contempt, mathematics has a feeling of doing whatever it wants.

Interestingly, in international subject competitions, Chinese mathematics cannot be considered overlords, but can only be called a strong country, but in physics subject competitions, what China shows is called dominance, which is much more powerful than mathematics.

Yan Pengfei also came to join in the fun when he heard this. He also looked down on those who studied physics next door: "Great god, stop learning physics. Learning physics is a group of sons, all depends on us math fathers. Without calculus, how can there be the law of gravity in physics? Humans invented calculus. Even without Newton, the law of gravity will be extended sooner or later. Calculus is Newton's greatest creation. The law of gravity is directly derived through calculus based on Kepler's theorem. The group of sons who studied physics always say that Newton discovered gravity because he was hit by an apple. He did not recognize our math calculus. Isn't the law of gravity discovered because of calculus?"

Li Xuan looked at Liang Zhihui and Yan Pengfei speechlessly. Are you two having a conflict with the physics competition class next door?

Liang Zhihui looked at Yan Pengfei, nodded with relief, and continued:

"Little Feifei, you finally have one thing that I think is the same as me. Those physics sons like to follow our math father's footsteps. For example, with Riemann geometry, even without Einstein, as long as the speed of light remains unchanged, general relativity will be introduced sooner or later, it will be a few years later. Well, now that the theory of relativity comes out, most people in the world think that the credit is all physicists, and if there is no mathematician, is it angry?"

"I also heard that Einstein had previously derived the equation of general relativity, which was a nonlinear equation. He didn't know how to calculate it. He was very troubled, and he didn't know how to calculate it himself. He had to calculate it until the year of the monkey and the month of the horse... At this time, the Russian mathematician Friedman came out and calculated the solution to the nonlinear equation of general relativity, and obtained the age of the universe."

"Okay, as soon as we discovered that we were in the age of the universe, physicists became lively again, the Big Bang, and the black hole theory made a brilliant debut... Really, the group of physics next door, without the help of our math father, what can these sons do?"

Li Xuan twitched his lips, remembering a professor whom he met while training at Peking University Winter Camp, and he also despised physics.

Professor Tian said at the beginning of class: "Students, you must study mathematics well. Physicists are counting on you, waiting for you to study new mathematics, and then get to physics! If you have not made any progress in learning mathematics and have never understood how to solve nonlinear equations, modern physics will not be able to develop!"

It's simply speechless.

Li Xuan really wants to say, is it to instigate conflicts between physicists and mathematicians? What is the father and son, they are clearly brothers. Many scientists in history are both great physicists and mathematicians.

"You guys go away, I just want to watch a physics quietly."

Li Xuan couldn't help but complain.

"God, you are betraying the revolution, I don't like you anymore!" Yan Pengfei showed a disgusting expression.

"Go roll!" Li Xuan really wanted to smash this Feinman physics lecture notes on Yan Pengfei's face.

"Hehe!" Yan Pengfei moaned and turned around and slipped away.

Li Xuan felt a little helpless and looked at the book with a silence. It was actually very interesting to continue physics because when it comes to reality, physical theory has a sense of reality that is within reach.

How to use mathematics to describe this world? Physicists will tell you that the prophecy of Pythagoras's everything is counted has come true.

Liang Zhihui couldn't help but look at Li Xuan for a few more times, and was sure that Li Xuan wanted to look at physics, but didn't know what to say.

Of course, he believed that Li Xuan could handle physics. As a math father, he couldn't even handle physics sons. Where is the dignity of being a father? Could it be that his son could still turn against the will of heaven? It's ridiculous.

He turned around and recalled the physics paper he scored in his seventies during the monthly exam. The difficult years he was rebelled by his son, and suddenly fell into strong self-blame.

...

...

Then, somehow, the statements of Liang Zhihui and Yan Pengfei spread to the physics competition class next door.

In the physics competition class next door, Sun Xiaoyu loved physics and was fascinated by the theory of relativity. She has been studying physics since she was a child, and she was unhappy when she heard this.

He led a few people to come to Liang Zhihui and Yan Pengfei, who smeared physics, to theory. When Yan Pengfei came out, he said with a smile: "Hey, Pengfei, long time no see. I heard you say physics is the son of mathematics?"

Suddenly, many students in the class came over, and Li Xuan also noticed that the next class was coming, and he was speechless. So many people were watching. Of course, Yan Pengfei couldn't be timid when he saw it, "Isn't it?"

Sun Xiaoyu stood at the door of the back door of the classroom, glanced at Yan Pengfei sideways, and sneered: "Mathematics is just a tool, physics is the father! Without the help of the physics father, no one would notice the so-called mathematics? Improper numbers? Log? Please! Apart from buying groceries, use addition, subtraction, multiplication and division, what are the uses of mathematics in reality? Our physics is different, and we need to use physics knowledge everywhere."

"Bad! I haven't used physics knowledge."

"No physical knowledge is needed? Do you use love to generate electricity at home?" Sun Xiaoyu looked shocked.

Yan Pengfei was choked and was annoyed: "Sun Xiaoyu, how many days have you not seen you? Come and find fault?"

"Yan Pengfei! You are the one who finds fault first!"

"Okay, okay, stop arguing." Qiao Siling stood up and persuaded her, raising her mouth and not wanting to argue. She knew Sun Xiaoyu, who had been in the same class before, was very physically strong, and even she admired her.

"Siling, don't worry, this is a battle between men." Sun Xiaoyu glanced at Qiao Siling, wrapped her hands around her chest, leaned towards the door, and looked at Yan Pengfei, saying proudly, "The relationship between mathematics and physics is like a plane and love love. That's right, I didn't target you who are studying mathematics. I just said that those who are studying mathematics on the spot are masturbating in the air every day! The research is all virtual! Our physics is different, we love love with the real world every day."

Qiao Siling's face turned red when she heard this, and her eyes showed a strange light, but she couldn't say anything.

When several students from the physics class next door heard it, they immediately applauded with thunder and thunder.

"Yes, I really sympathize with you those who study mathematics! How painful it is to masturbate every day!"

"Xiaoyu is awesome!"

...

"Damn it!" Yan Pengfei was stunned when he heard this, and found that he could not refute it. Not to mention him, the rest of the class in the mathematics were also shocked, and he felt speechless.

Liang Zhihui also scratched her head, why did she feel that Sun Xiaoyu seemed to make sense? Physics is studying reality compared to mathematics.

Yan Pengfei's eyes turned to Li Xuan. According to convention, when he encountered problems he didn't understand, he would choose to ask for help from Li Xuan. His eyes were very clear, just "God asked for help!"

Li Xuan understood this look, was stunned for a moment, and thought for a while and suddenly said, "I remember that scientific research shows that love with his girlfriend is not as good as a plane. Learning physics may be more painful than learning mathematics? Is it really happy to learn physics?"

Sun Xiaoyu was smiling, caught off guard and was choked. She turned to look at Li Xuan, her expression fell into a dull state.

Qiao Siling heard the sound and turned around and saw that it was Li Xuan: "……………………”

Liang Zhihui changed her hand and scratched her head.

What does it mean to make people kneel as soon as they open their mouths? Yan Pengfei opened his mouth wide and looked at Li Xuan in surprise. As expected, at the critical moment, math still has to be saved by the great gods. Then he laughed and pointed at Sun Xiaoyu and said:

"That's right. I didn't target you those who studied physics. I just want to ask, can you really feel the so-called happiness from it?"

Several students in the physics competition next door were silent and were collectively confused. They remembered the difficult years of studying physics and had to do experiments. Their hair was about to fall out. Finally, they shook their heads and left.

"Think about it carefully, it's still comfortable to masturbate!"

"Everyone has dispersed."

...

Li Xuan watched the group of physics-study competitions leave with amused, not thinking about so many strange things. He only knew that learning physics could improve his understanding of mathematics.

Mathematics is language.

Physics is to build a good model of the universe.

Physics is about studying how our world is, mathematics can build other models, and study what other possible worlds will be like. Both are interesting, have the value of research, and there is no conflict.
