My Sister is Very Obsessive

In the second class, the teacher continued to talk about the content of the first class.

A person with high academic achievement in a major will inevitably have another one, or be extremely good in several fields.

For example, the famous Mr. Yang Zhenlin, he is a recognized physicist, but he also has a lot of attainments in music.

The old professor who gave us lectures on traditional culture has high achievements in medicine, but his attainments in traditional culture are also not low.

So this goes back to what he told us in the first class: developing a hobby will have a very positive role in promoting one's own career and life.

After listening to the class carefully, the time will pass quickly.

The get out of class bell rang, but the old professor still had a little bit of content to finish, so he asked us with a kind smile,

"Don't mind delaying get out of class for a few minutes!"

Of course, in this case, everyone is very happy to express that they don't mind. Unlike high school, university teachers rarely procrastinate, so occasionally procrastination makes students feel involuntarily that this teacher is extremely responsible.

In fact, in fact, university teachers are not as serious and responsible as high school teachers. Some expert professors are not willing to teach students at all. The reason why they teach is just a task imposed by the school. How many hours of teaching tasks the teacher must complete each school year.

Of course, this is the case at the undergraduate level, but it is another case at the graduate level.

Graduate students all have directional mentors, but... Graduate students often call their mentors "bosses" in private, because their relationship with their mentors is more like "employees" and "bosses".

The tutor takes his graduate students to take over the project, do the task, and then pays them salary, no, it should not be called salary, it should be called living allowance!

As for doctoral students... Hehe, graduation depends only on luck, good tutors will be happy to watch their students graduate, and some tutors who "knock the door", if they feel that you are using it very smoothly, it is estimated that it will take seven or eight years. won't let you graduate.

I'm not being alarmist, but some doctoral students are really reduced to kneeling in front of their teachers and begging for forgiveness!

After a few minutes, the old professor punctually dismissed everyone from get out of class.

Most of the students flocked to the teacher's exit, while a few students ran around the podium and chatted with the teacher enthusiastically.

This is an elective course. There are sophomores and juniors taking electives. Of course, there may also be seniors who have insufficient elective scores.

The colleges and departments where the students are located are also different. After all, like this optional course, each college has drawn the selection.

My sister took the schoolbag and pushed me angrily to urge me to leave. Maybe she was afraid that the girl who asked me for an autograph before came to chat with me again.

As I passed the podium, I heard a student asking the teacher,

"Teacher, I have graduated, can I choose you as my doctoral supervisor?"

"Yes you can!"

The teacher put away the laser pointer that controlled the projector and looked at the classmate who asked her with a kind smile,

"I very much welcome the students of our school's medical school to stay in the school for Ph.D., but I don't recommend it to other colleges!"

After listening to the teacher's words, I immediately fell in love with him.

Although our school is not a double first-class university, in the field of medicine, it can still be ranked first in the country.

As for other majors, it seems a bit reluctant.

Then I was pushed out of the classroom by my sister.

I couldn't hear their next conversation, which made me a little regretful, so I involuntarily glanced back, and this glance was discovered by my sister, so the vinegar jar was broken!

"Heh, didn't I just ask you for an autograph, I'm still reluctant to let others go!"

This sour tone made my gums feel weak.

So I stretched out my hand and pinched my nose, and pretended to gently fan in front of me,

"It's so sour!"

My sister stared at me angrily.

"As you stare, your pretty little face will be filled with your big eyes, and then you'll be like a Martian on TV, with huge eyes."

My sister didn't answer me, but grabbed the clothes around my waist and gave me a headbutt.

I coughed twice, and looked at my sister who didn't pinch speechlessly,

"Did you hear when you came out just now that a student was consulting the teacher about his Ph.D.!"

"No!" Sister's tone was cold, "I don't read a Ph.D.!"

"Study medicine and do not study for a Ph.D., it is estimated that it will not be easy to get along in the future!"

"Who said I'm going to be a doctor!" My sister rolled her eyes at me speechlessly, "When you go home and inherit your mother's company, I'll be your secretary!"

"You said, if we studied medicine and inherited our mother's company, will it bring down the company?" I was a little worried, but I'm actually not very interested in operating with the company.

"You don't know there are professional managers. Many of those family businesses are run by professional managers. Otherwise, do you think that every generation of them will produce talented business tycoons?"

Uh... Listening to what my sister said, it seems to be the same!

Chatting and walking with my sister, I walked to the playground, walked around the playground three times, and then left the playground, planning to send my sister to the dormitory.

On the way, my sister suddenly asked me curiously why the Martians in the movie have big eyes.

This question is a good question, I am not a Martian, how do I know, but it feels a little low to answer directly, so I explained it to her from a biological point of view,

"Biological evolution is to better adapt to the natural environment, right!"

My sister took my arm and looked at me with beautiful eyes.

"Mars is farther from the sun than the earth is, so the light on Mars is not as bright as the light on the earth, so if there are positive Martians, they will have evolved a pair of large eyes to enhance light sensitivity!"

"Is that so?"

My sister looked up at me with a confused look, her white and tender fingers lightly poking her lips,

"Then why don't they purify the inner structure of the eye to improve light sensitivity, but to increase the light sensitivity by enlarging the eye?"

"Your guess is also possible!"

I smiled and nodded,

"After all, there are no aliens in the world, so the shapes of those aliens are just imagined by humans themselves."

"Then can I imagine giant aliens as tall as Mount Everest?"

"This... The size of the creature is related to the gravitational force of a planet, the atmospheric pressure, and if it is a creature that breathes oxygen, it will also be related to the oxygen content in the air. If your fantasy is decoupled from scientific reality, it is pseudoscience."

"I can understand the impression of gravity and atmospheric pressure on the size of organisms, but why does atmospheric oxygen also affect the size of organisms?"

"Stupid!" I flicked my fingers on my sister's clean forehead, "The bigger the body size, the more energy it consumes, and almost all of the biochemical energy of the human body comes from oxidation reactions, so the higher the oxygen concentration, the faster the oxidation reactions. The faster it will be, the more energy will be released per unit time!"

"So that's how it is!" My sister nodded thoughtfully.

"Why are you suddenly curious about this!"

"Because..." My sister turned her head to look at me, and then suddenly smiled, "Don't tell."

"why!"

"Because you started talking to other strange women in front of me today."

"Do I have it?"

"The woman who asked for your autograph, don't pretend to me, hum!"

"Then I'll sign one for you too!" I said with a smile.

"I don't want your stinky signature!"

"But I have to sign!"

"I won't give you paper and pen, where can you sign?"

"Who told you to sign with paper and pen?"

As I said that, I held my sister's little face, and then gently poked on her pink face,

"Are you satisfied with my signature?"
