I ran into your channel while looking for some notes on Chen's notation and I got to say, this playlist is brilliant!! I liked it for two specific reasons: 1. It's concise and up to the point 2. You explain things in a clear way. Thank you Rachel and keep it up!
Think of a university/school setting where a department has many faculty/teachers working in there, and a faculty member usually is associated with 1 main department. Example a Computer Science department has many faculty.
