I Just Want to Be a Quiet Top Student

In June, Yanda undergraduates are taking final exams in various disciplines.

"In the 23rd century, all human beings migrated to alien planets. In 3329, as a historian, you were sent back to Earth for investigation and found that the robot society on Earth is still operating. What is the content of the history books written by robots?" - ——This is an exam question for the history school.

"If zombies exist, what is the biological principle of zombie formation?" --- This is the exam question of the School of Biological Sciences.

"Because of the rapid population expansion, the continuous deterioration of the environment, and the shortage of food supply, human scientists have adopted genetic engineering techniques to reduce the size of all human beings to the size of an ant. Please describe the social structure characteristics of human beings after entering the 'miniature era'." --- This It's an exam question for the Department of Social Sciences.

Compared with the test questions of these colleges, the physics questions given by Shen Qi are quite conventional.

"The cat box is broken, what is the state of the cat? Emmm, which professor gave this question?"

The students of the Institute of Physics are used to boring and cumbersome physical formulas, and they showed great interest in this question about Schrödinger's quantum cat.

Answers come in all shapes and sizes, and students let their imaginations run wild, based on fundamental principles of physics.

The teaching assistants are responsible for marking the examination papers of the Academy of Sciences. There are standard answers for the first 75 points, and the Schrödinger quantum cat accounted for 25 points, and there is no fixed answer.

Shen Qi confessed to the teaching assistant: "Schrödinger's quantum cat question, as long as the students' explanations are reasonable and can justify themselves, they can get at least 15 points."

The scoring standard is very loose. If students can get all the previous 75 points, plus the score of the last question of "open ending", then they will have 90 points.

"Quantum Physics" is the core compulsory course of the Institute of Physics and Technology. A higher score in this course will have a certain effect on improving the GPA of the students.

The teaching assistant Xiao Tao did not dare to be sloppy in grading the papers. She also read step by step from an undergraduate, and she knows how difficult it is for juniors and younger sisters.

"The box is not opened, the kitten is both alive and dead, and the state of life and death exists at the same time. The box is opened, the kitten is alive within a certain probability, and dead within a certain probability... Hey, this poor cat The little cat is so miserable. Fortunately, this is just a hypothetical, a physics test question."

Due to the limited conditions of living in the school dormitory, it is difficult for Xiao Tao to keep cats, but she likes cats very much and often feeds stray cats on campus.

There is a doubt here. In Schrödinger's great physics hypothesis, why do you have to use cats for experiments? Xiao Tao looked up at the sky and pondered, oh, it’s getting too far, let’s get back to the topic, grading papers.

As a Ph.D candidate in physics, Xiao Tao had to admire the wonderful ideas of undergraduate students.

Regarding Schrödinger's quantum cat problem, the answers of some undergraduate students go beyond the scope of physics.

"After the cat box was shattered, the cat entered another time and space, existing in the form of an 'elf'." -- This is the answer of an undergraduate student.

"According to the principles of quantum mechanics and general relativity, this cat has returned to a certain time point in the past. It lives in peace with most humans, but has a grudge against physicists." ——This is another undergraduate student Answer.

Xiao Tao couldn't help but laugh: "Have you read too many online novels? I'm sorry, I can't give you even one point."

Another undergraduate student wrote on the test paper: "Because of the accidental shattering of the box, we have no chance to observe any quantum state, that is, a certain state that the cat may be in. We can be sure that the nucleus is still in all possible states. In a superposition of the cat, it's in a state where it's connected to the nuclei of the same quantum state. So, based on this particular setup, the cat is everywhere. I mean, the cat has Possibly in different places at the same time, we may even find several copies of it. Answer."

"This junior's answer is really thoughtful." Xiao Tao was unable to give a score for a long time.

There are two grades for a final test paper, 70-80 and 90-plus. Xiao Tao picked out a few controversial test papers and submitted them to Shen Qi for a decision.

"What's the matter, Xiao Tao, it's hard for you to give marks for the brains of your juniors?" Shen Qi smiled, and reviewed the test papers that Xiao Tao brought.

"One year is better than the last, and this year's newcomers are the strongest." Xiao Tao knew that the museum has always been rich in geniuses and geeks, and some young people's brains have broken through the sky.

"Traveling through the flow?" Shen Qi reviewed a test paper. The first questions of this test paper scored 55 points, and the answer to the last question, Schrödinger's quantum cat, was seriously off topic.

"Failing a subject is a very uncomfortable thing after all. This student Chen Xinjie, has he ever skipped a class?" Shen Qi asked.

Xiao Tao checked the information on the mobile phone and said: "Student Chen Xinjie never skipped class, and his homework was handed in on time. His compulsory experiments were successfully completed, and he took the initiative to clean the laboratory. It seems that Chen Xinjie is a diligent and full of enthusiasm. Fantastic big boy."

"Oh, I see." Shen Qi wrote a score of 63 on Chen Xinjie's test paper.

"Professor Shen is very nice." Xiao Tao laughed. If it were her who gave the final score, student Chen Xinjie might fail the subject.

"I used to be pretty bad." Shen Qi told the truth, "In the early years, countless students failed my subjects. I used to think that the most important thing for people who study mathematics and physics is talent, imagination and rigorous logic. The perfect combination. Students don’t need to take my class, as long as they can answer my questions, I will give them high marks, even full marks.”

Xiao Tao suddenly realized: "I heard that there was a class of students who failed the electrodynamics final exam by 73%...Professor Shen must have written that exam paper!"

Shen Qi said: "The electrodynamics paper is indeed difficult, Xiaotao, you can't just look at the 73% who failed there, isn't there still 27% of the physics students who passed that class?" Yet."

"I... I am the student of that class of the Institute of Physics!" Xiao Tao was sweating profusely.

"Such a coincidence?" Shen Qi was quite surprised, and asked again: "How much did you score on that paper, Xiao Tao?"

"59.5..." Xiao Tao was so sad, she stared at Shen Qi pitifully, and asked, "Professor Shen, can you tell me now, where is the 0.5 point deducted? The first and only time in my life The one time I failed a subject, I gave it to you, Professor Shen. Professor Shen, you were really bad before..."

"At that time, Xiao Tao, you were in your third year of junior high school. Now you are a PhD student. It's been so long, I can't remember the details. Hehe, this is not the point. Isn't the point of today discussing this quantum physics test paper?" Shen Qi chuckled, persuading Xiao Tao earnestly and persuasively, letting the past go with the wind, and the most important thing is to live in the present.
