My favorite memory in high school is that I helped my AP physics teacher David in his research. After the end of the semester 1, David invited me to help him make a GUI program for controlling wave generators in order to generate a suitable wave to bring the laser to a stable state. I accepted his invitation and went to his lab on a Sunday.
On that day, David and I studied the application programming interface of the generator and planned how to design the program. We have met a lot of problem, but finally, we completed the GUI program using the Python language. Although the output wave still does not achieve high stability of the laser that the research needs, but it is the most memorable experience after I came to high school: to achieve the goal with David and try to solve the problems, and it is meaningful. So, this was my favorite memory from my first year in senior high school.
