"Today is the first lesson of this one-year course, in which I will introduce you to the interaction of neutrons from low to high energy on concentrated matter, compare neutron emission sources in accelerators and reactors, neutron capture cross-section and charged particle emission, elastic scattering and thermal energy, optical and small-angle scattering, static and dynamic structural parameters, penetration calculations and particle simulations, etc., of course, we need to understand not only for theoretical research, but also to understand how these contents can be used in radiation therapy, Specific practices in the research and application of industrial imaging and materials. On the first day of Duke's chosen course on "Neutron Interaction and Application", Professor Shrek, who was a little embarrassed, looked like he was getting old, and even his beard was a little gray, but he still spoke with a lot of energy.

So far, Duke has taken five of the eight professional courses, and in the department's professional courses, each professor is obviously concerned about a champion-level student in the class, so Duke has to enjoy the troubles of fame, and every time he takes a class, he becomes a "star" to answer the professor's questions, but fortunately, Duke is well prepared, and while satisfying the curiosity of the professors, the professors are also very satisfied with the regular answers.

"Generally speaking, this course is relatively small, and few non-majors take it as an elective, except for individual students in materials engineering and health technology. But today someone broke that record, Dr. Duke from the Department of Computer Science showed a hobby like no other, which made me very curious, is Dr. Duke here today? Professor Shrek changed the subject, and suddenly pushed Duke into the spotlight of everyone.

It's still like this, it's hard to be a celebrity, and it's even more difficult to be a genius celebrity at MIT, and even classes will inevitably become the focus, so many eyes have been staring, how embarrassing it is to call my brother to take a nap in the future. Duke secretly smiled bitterly, raised his hand, and stood up for everyone to watch, very much like a rare animal in a zoo.

Duke was very embarrassed and embarrassed when he was watched in public for the first time, after all, he had just come out of the predicament of being introverted to a little timid, and the pressure of being watched by so many geniuses at MIT was still very great. However, after taking several classes like this, now Duke has become more and more accustomed to being watched, which shows that people are really forced out.

"Dr. Duke, can you tell me why you chose this course as a minor? I really can't think of anything to do with artificial intelligence. Professor Shrek looked smiling, but Duke had a vague feeling that something was wrong. And misunderstood Duke's original intention of choosing this course, he did not want to be a minor major, but a major in a second major.

"Professor, as you just mentioned, neutrons have many uses in industrial imaging and materials research applications, and there is a very interesting intersection with my major in this regard, and I think this is the best reason for me to learn." Duke replied politely. This is indeed one of the motivations for his study, but the materials he studied are not for the improvement of the computer industry, but for the future nuclear energy refining project as a reserve, but this reason is not enough for outsiders.

"Oh, that's a great idea, I didn't expect Dr. Duke to have such a broad range of research, please be seated, and welcome Dr. Duke into the neutron research industry." Professor Shrek said, in fact, in his mind, he is a little disgusted with this somewhat ambitious student, and choosing eight courses in a semester is quite perverted, but the course you choose is not related to a major, which is simply too rebellious.

Is this the attitude of normal people to study knowledge? Although MIT has a genius, it's not that you are so rebellious. Professor Shrek doesn't know how Professor Pol approved this course plan because he was dazed, but since he was in his class, Professor Shrek didn't want this student to be able to get through the test easily, you are so easy to get credits for MIT's doctoral course, feel free to sign up for a course to listen to it by the way, and you can get a score by pouring water, that is too simple to think, Shrek will never allow his students to have this kind of luck mentality.

"Regarding the study of the course, we will leave some homework for you on Monday and Wednesday from 10:45 to 12 o'clock, and the questions of the homework will be posted on the school education website, if you choose my course, you will see, usually I will only accept the submission of homework on the education affairs network, and the deadline is before the class next Wednesday, because I will publish the answers to the questions online after the class on Wednesday. If there are some temporary notices of any courses, I will also use the campus network to send you an email notification, so you have to get used to the academic affairs website often. As for the grading of coursework, it will be handled by our Head Teaching Assistant, Miss Mara, who is also your after-school tutor, so please feel free to contact her if you have any questions. In terms of grading, 30 percent of the usual homework scores, 20 percent of the half-term test scores, and 50 percent of the final test scores. Of course, I know that sometimes you will come up with some reasons that I can't argue, such as you are getting married, you have to have an elderly person who has passed away, etc., I will accept any reasonable reason, but don't think that I will take care of the test results. Professor Shrek finished the precautions of the course and began to get down to business.

These are all clichés, Duke thought that this matter was over, and there should be nothing for him to do for the rest of the time, and he was exchanging ideas with Kerry about today's experimental topics, since the courses were basically thorough, Duke came to class just to make himself not too maverick, well, in fact, anyone who dares to choose eight main courses in a semester is already very maverick. Duke just didn't want to give MIT professors any more excitement.

"Dr. Duke, what do you think about this issue" Who knows that Professor Shrek seems to care too much about Duke today, and the questions he asks are always discussed with Duke, yes, the meaning of discussion means that there are actually some knowledge points that are not talked about in today's course, and they are also raised by Shrek to discuss with Duke, if it is not for Duke to "study" the entire course again, these problems will obviously become his embarrassing Waterloo. But now that the relevant materials have entered the knowledge space compiled by Kerry, Professor Shrek's problem today is no longer a problem.

Duke calmly answered Professor Shrek's almost difficult questions, put down his plan to deduce the laboratory questions in class today, and took Professor Shrek's course seriously.

"Dr. Duke, thank you very much for your cooperation in the course, honestly, you are the best student I have ever met, and sometimes I wonder, are you really an elective student majoring in computer science, if you want, I would be more than happy for you to come to our team to specialize in physics." MIT is all about advocating the strong, if Professor Shrek still has some criticism of Duke's ambitious course choice before class, but Duke's strong performance in this class completely moved Professor Shrek, Duke's solid foundation for an almost complete understanding of the course made Shrek launch a strong invitation to Duke after class, in Shrek's eyes, such a good seedling may not be able to meet one for more than ten years.

"Thank you for the compliment, but in my opinion, there are many intersections between computer and physics, and I think that after completing my major, I should have the opportunity to do more in-depth research in physics." Duke said gratefully that physics, especially nuclear physics, is his next focus, and it is undoubtedly a great thing to be favored by Professor Shrek, a well-known expert in particle research.
