This makes me incredibly grateful for my physics lecturers, all of whom would bend over backwards to assist their students' journeys towards learning any time any stumbled or showed a spark of curiosity that needed fanning into a raging fire.

I had lecturers give me bonus marks above 100% because I noticed issues like this and thanked me for helping to improve the course material!

These lecturers, when merely overhearing a curious "huh?" conversation between students would spend hours of their own time scouring the library for relevant information and just "leave" photocopies for students to find the next day.
