⚛ Mastery Map · Physics

A free, concept-first path through physics · one free book per phase · sources: OpenStax University Physics Vol 1-3 · David Tong's Cambridge lecture notes · MIT OpenCourseWare 8.04 (Zwiebach) · Khan Academy · HyperPhysics.

Built to never let a required concept slip past you — learn it, understand why it exists, solve it, revisit the "revise" links when they resurface. Mark a concept done and it comes back to you in 1, 3, and 7 days.
