A long time ago, at the beginning of this story, I was an MS student in Mechanical Engineering. I had gotten a job as a Teaching Assistant for a class called Mechatronics (a class focused on the intersection between mechanical and electrical fields). My job as a TA was to lead the lab sessions and help students with their final projects, which involved applying feedback control to some mechatronic system of the students own design.
Now, in academia a TA is kind of like a bartender or a barber, in that students will tell things to their TA that they would NEVER admit to the professor. As we were nearing the end of the semester and the final projects were looming, a student approached me sheepishly as if to ask a question and said hesitatingly,Can I be totally honest with you? I have no idea what 'feedback control'is. The other students in the class overheard, and expressed some relief in admitting that they had the same difficulty.

This was surprising, since one of the prerequisites for the mechatronics course was another course titled Feedback Control.All of the students in Mechatronics had passed this course, and many of them had done very well. However, in another sense this admission was not surprising at all, since I myself had experienced the exact same thing when I took the class. I had taken feedback control and done well, and I also finished the course with basically no idea what feedback control was.Wha
