"Tell me, what's the situation?" Shen Qi said he was concerned when he heard that his students were isolated.

"There is a project that is very compatible with my major, and I really want to do it, but my application for project approval was called back. A similar project, proposed by another associate professor, was quickly approved. ”

In front of the student Xiao Zhu, Yu Lei talked and laughed.

After Xiao Zhu left, Yu Lei revealed his heart frankly, and he was a little depressed: "This algebra topic is the most suitable for me to do, and I am confident that I can do it well, but now...... What should I do? What can I do!"

This project is the academic capital of Yu Lei's promotion to full professor, he has passion, but he has encountered some obstacles

Syllable!

Shen Qi slammed the table and scolded Yu Lei angrily: "Enough!"

Yu Lei was startled and didn't dare to speak.

"What should I do? What can I do? Woo woo, I'm so pathetic. Shen Qi artistically simulated Yu Lei's inner activities in an exaggerated resentful tone.

Yu Lei looked at Shen Qi with a complicated expression, speechless.

"I ......" Yu Lei came to Shen Qi today, firstly, to complain, and secondly, to hear Shen Qi's advice.

As a result, Shen Qi scolded him, which caught Yu Lei by surprise.

After Shen Qi finished scolding Yu Lei, he touched his black cat Maxwell, and said calmly: "Yu Lei, be tough, don't be like a weak girl, how much money can be approved for an algebra project? When you go back, what should you do, doing math projects is not playing games, and you can't choose a hero if someone else chooses them. He does his, you do yours, what does it matter?"

"Okay, I see. Yu Lei nodded, and his mind gradually calmed down.

"I don't want to get involved in all the you have inside, you have a fair academic competition with others, and I support you spiritually, but I won't do anything special for you in my name. But if someone, whoever they are, who is unfairly negative to you in a non-academic field, then I will do you a few words of justice. Shen Qi made a final summary.

"Thank you, thank you, Brother Qi, I know what to do. Yu Lei got up and said goodbye.

After a few minutes, Shen Qi left the office and walked towards the teaching building, he had a high-quality class for undergraduate students today.

This time, Shen Qi will not talk about high mathematics, but about high generations, because the teaching objects are undergraduate students from the School of Mathematics and the School of Physics.

The new regulations on undergraduate teaching in colleges and universities have been promulgated for a period of time, and the state requires the abolition of undergraduate "water courses" and the establishment of more high-quality courses.

Professors must give lectures to undergraduates, and the number of class hours is arranged by each university.

The regulations of Yan University are that each full professor's undergraduate class hours shall not be less than 10 hours in a semester, and there is no upper limit.

One class hour is one class, Shen Qi has to give at least ten classes to undergraduates in a semester, he is very happy to teach undergraduates, everyone knows this truth, strong undergraduates are strong country.

Shen Qi came to the big classroom, and the classroom was full.

Two-thirds of the students are first-year students in the School of Mathematics, and the rest are first-year students in the School of Physics.

Advanced algebra is a compulsory course for students in the School of Mathematics, and students majoring in physics in the School of Physics also study advanced algebra.

A strong undergraduates will make the country strong, and a strong freshman will make the undergraduates stronger.

To train socialist successors, we must start from the freshman year.

In addition to the first-year students of the School of Mathematics and the School of Physics, there were also some young teaching assistants and lecturers in the classroom, who came to listen to Shen Qi's excellent courses with a learning attitude.

Shen Qi came empty-handed, without a lesson plan, the lesson plan was in his heart.

In this high-quality class, Shen Qi began with an emotional recitation:

"The numbers that are always circulating and the imaginary numbers that never show their true colors depict a concise trajectory to a certain point. ”

"Yuan didn't appear anywhere, but a fairy came down to earth and π. ”

"π, π, she fell into E's territory, and she was ashamed to have feelings for I. ”

The bodies of π, E, and I were tightly huddled together, but when 1 appeared and added to them, the world changed without warning. ”

"Dust to dust, dust to dust, everything to zero. ”

Shen Qi finished the recitation with a smile, and asked the audience, "Why is it attributed to 0?"

The first-year student at Yan University was very smart, and someone replied, "Euler's identity!"

"Very good. Shen Qi nodded, and wrote a classic formula on the blackboard, Euler's identity, e^iπ+1=0.

"Professor Shen's teaching method is very interesting. "The young teaching assistants and lecturers were amazed that Euler's identity was known to everyone, and it was the first time they had seen it in prose.

"Actually, the passage I just recited, the original author is Yoko Ogawa, and I made some adaptations. Yoko Ogawa is a female writer who beautifully and accurately interprets Euler's identity from the perspective of a writer in the book "The Doctor's Equation of Love". It seems that Ogawa is a female scholar who studies both arts and sciences. Shen Qi is also a well-read person, and he has read more than many Chinese students.

"Ms. Ogawa's mission is over, now let's focus on today's protagonist, Ora. ”

Shen Qi tapped Euler's identity on the blackboard and said, "Euler is one of the greatest mathematicians, his academic thinking in many aspects is ahead of his time, he looked at the things of the 20th century in the 18th century. ”

"Euler's identity on the blackboard is one of many Eulerian formulas, and it's very classic. Next, I'm going to write another very wonderful Euler formula, which was considered unthinkable in the 18th century. ”

Shen Qi turned around and wrote another Euler formula on the blackboard: 1+2+3+4+5+......=-1/12

At first glance, this is impossible.

After adding the positive integers infinitely, we actually get a negative number.

In the 18th century, after Euler wrote this formula, no one could understand him, because he was invincible, so he was lonely.

Today, in the 21st century, there are also many people who find it difficult to understand why an infinite number of positive integers are added together to get a negative number.

The students of the School of Mathematics and the School of Physics did not make a fuss, they are the best group of first-year science students in China, and they can understand this Euler's formula of "positive numbers are infinitely added to obtain negative numbers" from the height of the theoretical foundation of the 21st century.

The students, including teaching assistants and lecturers, just don't know what kind of medicine Professor Shen sells in the gourd, and what will he talk about next?

Next, Shen Qi said: "Students who participated in the Olympiad in high school, please raise your hand. ”

Brush Brush Brush!

Raise a bunch of arms.

The classroom atmosphere is more active, and more and more students are keen on subject competitions these years.

Shen Qi was a little surprised, and 80% of the students present raised their hands to say that they had experience in the Olympiad competition.

Shen Qi: "Then I'll randomly order the best-looking one, come, young man, you go to the stage to write the proof process of Euler's formula, use the method of middle school students, and do not use the knowledge of advanced algebra." ”(https:)
