Chapter 244 (1/2)
Li Zheng was led out of the school, found a familiar Sichuan snack bar, ordered a few hot dishes, which blew the bottle to chat.
He was more talkative and more talkative when he was drunk.
Just now I was talking about mechanics, and then I sprayed quantum.
Spray spray extends to Schrodinger's open marriage, how to be dignified, how to be honest and dignified, the red flag in the family does not fall, the city flags flutter.
Then, the topic of drought and flood died. The topic was transferred to ”sexual depression of science students”, indicating that he wanted to do a paper on the relationship between sexual life and scientific research efficiency when he was undergraduate. However, he thought this direction was OK. He modified the topic and turned it into ”the influence of sexual life on IQ”, and then he changed the topic to ”the influence of sexual life on IQ”, and There was no more.
He has not thought that he can do this topic, not because it is not reliable, but to take care of the self-esteem of the majority of science students.
When he talked about it, Li Zheng was a little bit too hard to hold. He wanted to return the topic to study, so he asked a hydrodynamics question.
He was also very pleased to understand the problem and gave Li Zheng a topic immediately.
”You see, what a topic this topic covers hydrodynamics, biology, ergonomics.” ”The key is still a virgin land. Do you know how difficult it is to find this year?”? I mean the virgin land in scientific research. ”
Li Zheng coughed: ”there is a person named Bi guide in the bar. He may be interested in this topic.”
”No way.” Solve its dispute firmly raised hand, ”such a good topic can not give Jinghua.”
”Do you understand the teacher seriously What is the significance of this topic? ”
”Yes, it has a wide application prospect.” I will say something. You can feel the automatic boom, the suppression injector, the double expansion ring sleeve Do you feel that? ”
”Here These needs, as if medicine has been resolved. ”
”Can that be the same? Don't you think physical paths are more interesting? ”
”OK...” Li Zheng shook his head and sighed, and said with hesitation, ”it is OK to talk about it while eating But I am still more concerned about what you are really doing. These things sound like... ””
”Civil science?” He laughed and opened a new wine. ”It's OK. I've been spraying it for more than ten years.”
”No, I want to say Doraemon.”
”Ha ha, it doesn't matter.” I was half a bottle of confusion, looking at Li Zheng's eyes, and finally couldn't refuse to sigh, ”I haven't done anything now. If someone wants to give money, I may really go to double the expansion ring set...”
“……”
”Well, I know you're upset with me.” He put down the bottle and quickly took two dishes. ”Finish it quickly, and go back and give you a lecture.”
”No trouble, teacher.” Li Zheng picked up the bottle instead and poured himself a large half of the cup. ”But, with people like you, I will unconsciously want to absorb the nutrients in physics, and want to know what kind of research and content you have done in such early champions.”
”Research, thinking?” ”It's still early, Comrade Li, I don't want to say, you shouldn't listen to it now.”
”It's ok...” Li Zheng sincerely raised his glass and said, ”I have psychological preparation, even if you are really a perpetual motive, I can accept it. I believe in your knowledge and doubt your personality at first Now, in turn, I trust your personality, but I doubt your knowledge... ”
He was stunned, but he picked up the bottle quickly and touched Li Zheng.
”Thank you for your trust.” I will show you my way of thinking and training as much as possible. But I really think about physics, sorry, it's not yet. ”
”Why?”
”No, no, No.” To solve the trouble put down the bottle, the face no longer eyebrows dance, but covered with a layer of numbness.
Li Zheng said anything, he also did not answer, even if said double expansion of what he also did not answer.
He just took out his cell phone and walked to the counter with some slant, leaving only a back image of an ordinary middle-aged drunk.
On the way back, they didn't say a word.
When we got back to the small classroom, it was already 8:00 p.m. in the big experimental classroom next to, the people of the training team were still doing experiments.
There is no interest in solving the problem. Just go back to the blackboard and write it up.
Although some drunk, he also did not have much fun, but the content is still a little.
”A few hours ago, you learned a new way to solve the problem.”
”Draw the physical image, and then convert it into a mathematical problem, and restore the physical results after calculation.””It's not really a new method. Since middle school, physics problems can be solved in this way.”
”Only now, after mastering the micro sum product, there is no longer any obstacle to the transformation between physics and mathematics.”
”But that doesn't mean that all physical problems can only be transformed by calculus.”
”In other words, calculus is the most stupid method.”
”The picture in the computer, you know, is to divide a picture into millions of pixels, and then show the whole picture by describing the color of each pixel. This is the most stupid way.”
”If we're smarter, we can record the characteristics of the image to describe it.”
”For example, in a picture, one million pixels in the upper left corner are all black. We just need to record the location of critical points and black information.”
”And this is the Eulerian description of fluid mechanics.”
”Next, let's put down the idea of switching calculus and let's go on a thinking journey with Lao ou.”
In the following class, different from the original sarcastic jump, the solution to the disputes gradually becomes gentle, and many easy to understand guidance and examples are added to make the whole class soft and comfortable.
Of course, when it comes to mathematics, it's still very steep. It's always a sudden ”micro”, and then Mao can't understand it.
I don't know how long, suddenly came a knock on the door.
After resolving the dispute, the two boys stepped into the classroom and looked at Li Zheng to reconcile his dispute, with a little sadness in his eyes.
Li Zheng noticed that there were more people gathered at the door of the classroom. Lu Yang was trying to get everyone to disperse, but he could not.
He rubbed his head, which might be the strength of wine. He asked impatiently, ”what's the matter?”
”Mr. Xie We also want to hear... ”
”You can't just open a small stove for him and push us all out...”
As soon as these two words were said, it was quiet outside.
”Listen.” Jieqifen pointed to the empty seats in the classroom and said, ”no, you are sitting.”
Two people a Zheng, then a joy, quickly found a seat in front of sit down.
A lot of people came in from outside, and the classroom was filled in a moment.
He shook his head and asked Lu Yang for a bottle of mineral water. After filling two mouthfuls, he began to talk again.
In an instant, gentle no longer, the content also returned to the original content of Li Zheng.
Cut into pieces, and then a little bit, it's all out.
It belongs to the rhythm that can't be followed by simple note taking.
Gradually
The number of people began to decrease
”Excuse me, Mr. Xie...”
”These I can't get the exam at all... ”
”How do I feel listening to mathematical analysis...”
”Go back to bed...”
”Li Zheng, can you understand that?”
After more than 20 minutes, all the people who just came in crowded out again.
Only Qi Yingnan, a man with thick eyebrows and big eyes, sat at the farthest place from Li Zheng and listened.
The solution of his constipation look at the same expression, also smile, throw down the chalk to ask: ”tell the truth, understand how much?”
”Zero!” Qi Yingnan Zhenzhen replied.
”What are you listening to?”
”The truth of physics!” Qi Yingnan didn't let him. He nodded, ”you asked at the beginning, who wants to get close to the truth of physics, I think.”
”Oh? Did you ask that? ” Li Zheng in the back row said in surprise, ”I want to do that, too.”
”Ignore you.” Qi Yingnan shook his head and seemed to have a grudge against Li Zheng.
Xie Qifen looked at his watch, and then looked at them. He couldn't help shaking his head and sighing, ”it's more than ten o'clock. Look at your virtues. Let me just say a little bit about it. I only want to be imaginative. You should not think too deeply. ”
He said, turning back to the water that had just been drawn on the blackboard: ”what I have just been teaching is nothing more than describing physical problems as physical images and transforming them into mathematical problem solving, right?”
They both nodded.
”And vice versa?” He took up the eraser and wiped away the water, leaving only the equation beside him, ”I only give you mathematical equations. Can you describe the physical image?”
They were stunned and then fell into thinking.
Then, Qi Yingnan first raised his hand: ”can't.”
”Why?”
”This mathematical equation is so simple that it can only describe the state of a fluid in a specific state in one physical environment.”
”Good.” He turned to Li Zheng and said, ”what do you think?”
”Still thinking about...” Li Zheng pondered, ”what if there are more equations? Enough to cover everything about this fluid? ”
”You're fine, too.” He nodded and then looked at Qi Yingnan. ”Describing physics with simple equations is actually what the sages of the classical physics era did.”After that, he turned to Li Zheng: ”now, scientists are trying their best to deduce equations that describe everything. There will be many and many groups, which is why modern science is too complicated.”
”Quantum mechanics, which I hate the most, is one of them.”
