I just received the feedback from students of the courses I delivered last semester (General Physics I part 2 and Advanced Topics in Theoretical Physics). The feedback was excellent, with a satisfaction index of 100%! Given the amount of work I put into preparing the courses, and the enthuasism I tried to instill, I was really happy to read the students’ comments, especially for the Advanced Topics in Theoretical Physics aka Cosmology course (see below) - the students really appeared to appreciate my efforts to always help them not lose sight of the big picture, even when the latter risked being obscured by the complexity of the calculations (especially when it came to deriving the Boltzmann equations). I do indeed find it important (not only in my work but also in my research) to, so to say, “not lose sight of the forest for the trees”. I found the feedback really rewarding, and the comments will motivate me to do even better in the coming semesters!
