## What is Field Notes Study Guide?

Field Notes rebuilds quantum field theory the way it was actually discovered — starting from something you can see and calculate: a mass on a spring.

From that single oscillator, you follow one continuous thread through normal modes, Fourier synthesis, continuum fields, Lagrangian mechanics, canonical quantization, and on to particles as excitations of a field — and, in the full curriculum, gauge fields and the Standard Model.

Every concept pairs three things:
- A clear, math-honest explanation with properly typeset equations
- An interactive lab you manipulate in real time — change a mass, a spring constant, or a wave number and watch the physics respond
- A grounded AI tutor that answers using an approved physics source packet, and returns uncertainty instead of inventing citations

Progress is paced by understanding, not seat time. Each concept asks you to predict, calculate, and explain to earn mastery evidence, so you always know what you actually understand.

Field Notes is for people who want the real thing — undergraduates, self-learners, and the endlessly curious — not another set of surface-level animations.
