This science of computer science and technology has deeply attracted our students, and it has been in the computer system for nearly three years. I have made some thinking. Originally, no matter how domestic or foreign countries, I like to divide this system into computer software. Theory, Computer System, Computer Technology and Application. Later, it became together, it became the current computer science and technology. I have always believed that this major of computer science and technology is impossible to cut into computer science and computer technology in the undergraduate phase, because computer science requires considerable practice, and practice needs technology; each person (including non-computer professional), Mastering simple computer technology is easy (including the original Major self-righteous programming), but computer professional advantages are: we have something that many other majors do not "deep", for example, algorithm, architecture, etc. . Non-computer professional people can easily make a chip, write a program, but they can't do a large system that the computer can make. Today I want to talk about computer science and will focus on calculation theory. 1 Some students exclaimed the wrong door: What is the system of this? Yes, you didn't go wrong, this is the computer science and technology department. The tradition in my country's computer science department is to cultivate people who do academic research, especially theoretical research (the direction is not necessarily there, but doing so much "). And the atrophic research of the computer, says, such as network safety, graphics image, video audio processing, which direction has a big relationship with mathematics, although it is a non-mainstream mathematics in the eyes of orthodox mathematicians. Here I also want to clarify my point of view: We all know that mathematics is the theory of abstract in the actual life, people to abstract theory into theory, the purpose is to use abstract theory to better guidance practice Some mathematics research workers like to use some existing theoretical knowledge to derive several festivals. I don't know that one: I don't know how to consider it. Second: His Inference can't find prototypes in real life, it is not guided practice. Strictly said that I am not an idealist, the theoretical connection between the political class, I have always guided the navigation mark I learned about scientific and cultural knowledge (at least I think computer science and technology should be in this direction).
In fact, our computer system math is only in good quality (typical engineering institutions generally open higher mathematics), we should learn mathematics analysis like the mathematics department (the Tsinghua computer is like a mathematical analysis, we The school computer college is also open, but the teacher said that it is still in accordance with higher mathematics), mathematics analysis of this science, our people have a complicated feelings about it. It is a mathematical course that is biased towards the certificate, which is very helpful for our cultivation of good analytical capabilities and reasoning skills. Mr. Wang Yihua, the Northern School of My Software Engineering Master, has taught us that the students of the mathematics go to the software enterprises to make software design and analysis work, and the computer system is a programmer, the reason is that mathematics Students analyze reasoning skills, from the perspective of training above our average. The strange phenomenon of the year is: the high school mathematics foundation of the computer system is a number of all-calios (I hope that the classmates who have not charged the other series), the number of teaching courses is only secondary to mathematics, but the effect after learning is not satisfactory. Is it a student who is not working hard, I have not seen it, the direction is wrong, it is not necessarily, why is there anything I am thinking. My personal is: the student of the computer system, the requirements for mathematics are different from mathematics, and the difference in physical classes is greater. Usually non-math majors? Quot; Higher Mathematics ", not to delete more difficulties in mathematical analysis, emphasize the set formula calculation. And the maximum use of mathematical analysis is exactly Going to the theoretical part. It is difficult to listen to the student of the computer system, the so-called "engineering mathematics" of the pursuit of calculation has completely entered the misunderstanding. Remember the formula of a pile of curved scores, can it be possible to understand Mathematics? That is not as good as the current check, why not pay? Do you have a good time to use Mathematica or Matlab. Even if you have a high-level mathematics, I want to see Mr. Hua Lugeng's "higher math introduction" "It is also much better than the general textbook. Hua Luogeng is doing more in mathematics, but this is the most important thing for us, the most important thing to say: first, it is the first to build China Institute of Computing Technology, this is the cradle of our country's computer science. In the case of he handed a lot of higher math theory to the technical personnel of industrial production, promoting the progress of China's industry. The third is that he wrote his life I have a lot of books, but the value of teachers and students in colleges is that he wrote "higher mathematics introduction" during the hospital in the patient's bed and his fantasy (Wang Yuan and it is said to be him. Colleagues, is the older generation of Chinese Academy of Sciences, the contribution of Goetbach guesses the whole world only in Chen Jingrun) This book is actually found in our library, to tell the truth, then the book is already a bug, Others will flash there, but I am very interested, I have seen it over and down. My biggest harvest is not the elaboration of theory, but in his theory is completely instantiated, in life. Model. This is also why I prefer specific mathematics. As I mentioned above, the theory has lost its meaning. It is because the theory is abstract from practical, so the theoretical research Can better guide practice, the theory that does not guide practice can be said to be worthless.
The most loved thing in the line is to recommend reference books for the schoolmates. There is no other idea, just want them to walk less. Chinese mathematical analysis, generally believe that the "New Speaking of Mathematical Analysis" is the best. Zhang Zhaosheng wrote a lot of books, but as long as every one written is a masterpiece in the field, this is certainly more prominent. This kind of old book seems not only to teach you knowledge, but let you experience the scientific method and the understanding of things. In case, your mathematics is too good, then go to the Phili Gold Cordz? Quot; Diji Tutorial "Good - But I think there is nothing necessary, after all, you don't want to go to the mathematics department. Jimmyvi "Mathematical Analysis Exhaust Set" is basically a computational book. The name of the book is very good, and it is not suitable for us. It is important to establish the establishment of mathematics ideas. It is high-efficient in the information society. Calculate this stuff or leave it to the computer. But now it seems to be the "mathematical analysis" of Fudan University, the higher education publishing house, is also a very good textbook. China's so-called higher algebra, equal to linear algebra, plus a point polynomial Theory. I thought this is a good side, because you can feel that the algebra is a structure earlier, not a bunch of matrices, and you have to mention Nanjing University Lin Chengsen and Sheng Songbai's "Higher Algebra" It feels quite comfortable. This book is quite comprehensive containing basic primary results of the polynomial and linear algebra, and also provides some useful and deep content, such as Sturm sequences, Shermon-Morrison formulas, generalized inverse matrices, etc. It can be said that as undergraduate students can eat this book, it can be a master. The good domestic high album textbooks also have the Tsinghua Computer System, Tsinghua Publishing House, a lot of bookstores, I will know. From abstraction At the point of view, the results in the higher algebra are just some examples of algebraic system. Mr. Mo Zongjian's "Mathematics" has conducted a deep discussion. However, Mr. Mo is very deep, As undergraduate, I am afraid that it is difficult to accept, but I have matured some of them later.
As discussed above, the computer system has studied higher mathematics: I know that it is better to know. The purpose of your learning should be: Apply an abstract theory to practice, not only to master the questions of the problem, but also master the spiritual ideas, but to theorem: Not a simple application, but master the proof process, master theorem The origin, train your own reasoning ability. Only in this way achieved the purpose of learning this science, it also narrowed the gap between our thinking between our classmates.
