An undergraduate thinking about PhD

  The first time I met a doctoral student today, I felt like seeing each other late. I used to think that doctoral students should be more comprehensive in their professional fields than graduate or undergraduate students, and there should be nothing special in other aspects. But through today's contact, I found that this is not the case. Not only do they have stronger professional knowledge than others in their professional fields, but they are also better than others in dealing with people, and their professionalism and quality are better than most undergraduates. It is much better to be a student or graduate student.
  What is the cause of the matter? It was the teacher who asked to do something before, including the program, PCB hardware, and motor related content. Because I am more familiar with software things, there are certain deficiencies in the hardware part. After writing the program, I found that it is not feasible to measure the hardware. Because only part of the hardware has voltage, and the other parts have no voltage at all, and the board was not drawn by me. I connected a mess of things on it. Give me a schematic and PCB file directly. The symbols on the schematic are all SS. , I don’t even know the company. For me, a very fresh junior, it’s like entering an unknown territory.
  After solving the software and other sensor stuff, the PCB board was never settled. After explaining the situation to the teacher, the teacher said to find someone to help me, so a student came in the afternoon. I didn’t know what academic qualifications were at the beginning. Later I found out that it was a doctor. Then I communicated directly with him, and I found that I was very relaxed. He first asked what the principle of this board is, and I talked about some things I have learned about how the drive motor rotates forward and backward. I don’t know enough, so I said some things that are relatively easy to understand, and I don’t know if he asks me questions later. Then he started looking for it from scratch. First, he looked for the power inlet, and then Baidu went to find the function of the power inlet interface chip. It came up to read the English document. At that time, I was stunned. Think about reading the English chip explanation document before, first of all go to WPS to translate it, or go directly to Baidu to find some translation website (some of them only translate a few pages, and then start to ask for money), the gap is immediately reflected. .
  After that, the teacher brought in a few more undergraduates, some of whom were at the same level as me and one level lower than me. I was very grateful to the teacher at the time, and so many foreign aids were found at once. After they came, I started talking with them, and the doctoral student left because he saw that we were picking things up. Then I talked to my peers, they didn't ask me the principle, and then asked me what was wrong, and then I told them that part of the board could not be powered on. After that, they asked me to power on the board, and I started measuring there, measuring this, measuring that, (I don't think they understand the principle of the board) It took about an hour to toss there. After a while, they told me that maybe I had a false solder, and they left after saying a few words.
  After a while, the doctoral student came and said to copy the PCB files and schematics, and said to go back to study and research, try to assemble it, I was always moved at the time, after all, I haven't done anything.
   When I went back to think about this matter, I found that the answer given by the undergraduate student was that I had a false soldering. Let me look for the error again. The answer given by the doctoral student was to go back and look at the principle and see if I could do it. Come out a similar PCB that you can understand. I think if I did it, I might also be like other undergraduates, starting to find the problem without knowing anything. The result of this approach is definitely that the problem has not been solved.
  Perhaps the significance of this study is no longer limited to the theoretical knowledge of books or actual practical results, but to improve a person’s ability to find and solve problems, and also has extreme personal charm and behavior. Great significance! There is a long way to learn, and strive to become the person you want to be. Come on!
