Physics
Physics notes from my high school, undergrad, and master’s level classes, along with some extracurricular explorations.
Based off my notes from the NU classes Physics 333-1 and 333-2, which were themselves largely based off one of my all-time favourite textbooks*: Introduction to Electrodynamics by David J. Griffiths.
*Admittedly not an especially competitive field, so this particular accolade doesn’t mean much in and of itself, but I do genuinely love this textbook.
