My notes (starting from) 2nd Year Engineering Science at the University of Toronto. Includes funny electives.
Edit: This is just for 拋磚引玉, because I don't understand enough of lectures now in 3rd year to make good notes.
Things I find obvious are not included in the notes. Things I don't find obvious are. What I think is obvious may not coincide with what you thing is obvious, and vice versa. Feel free to submit pull requests (I make a lot of typos).
