• Accelerator physicsUse whenever you design or check the transverse and longitudinal motion of a charged-particle beam — a FODO lattice, a storage-ring optics cell, an RF bucket, a collider's luminosity, a synchrotron-ra
• Classical mechanicsUse whenever you set up or solve a mechanics problem — a particle, a constrained body, an orbit, a small oscillation.
• Cosmology and astroparticle physicsUse whenever the expanding universe is the physics problem — scale factor and redshift, the Hubble parameter, the Friedmann equations, density parameters and flatness, how each component (radiation, m
• electromagnetismUse whenever you solve a field problem from Maxwell's equations — electrostatic potential, magnetostatic field, a wave in vacuum or media, or radiation — and must pin down the boundary conditions, gau
• Experimental method and error analysisUse whenever a claim rests on measured data — reporting a lab result, fitting a model to points, comparing theory against experiment, or reviewing someone's number.
• Limiting cases and asymptoticsUse whenever a derived physical result must be trusted — a new formula, a corrected old one, a reviewer's number — before it ships.
• Model building and approximationUse whenever a result rests on an idealization or an approximation — before you trust any 'ignore friction / small angle / ideal gas / linear response' step and before you report the answer it produce
• Order of magnitude estimationUse whenever you need to know the size of an answer and which physics matters before solving — setting characteristic scales, Fermi-decomposing a quantity to within 10^±1, forming dimensionless ratios
• Particle physics and the standard modelUse whenever you reason about elementary particles and their interactions — deciding whether a process is allowed or forbidden, computing decay widths, branching ratios, lifetimes, or cross-sections,
• Quantum field theoryUse whenever a problem involves relativistic quanta, fields with a Lagrangian density, Feynman diagrams, scattering amplitudes, cross-sections or decay rates, loop divergences, running couplings, or g
• Quantum mechanicsUse whenever a quantum result is derived or reviewed — a wavefunction, a spectrum, a measurement probability, an expectation value — before it is trusted.
• Relativistic kinematics and collisionsUse whenever a problem involves collisions, decays, or scattering of relativistic particles — anything where four-momentum bookkeeping, 'what is the CM energy?', 'is this above threshold?', or 'is the
• Special and general relativityUse whenever a problem involves speeds near light, boosts between frames, spacetime intervals, four-vectors, or gravity as curvature — anything where 'which frame?' or 'is this invariant?' is the crux
• Statistical mechanics and thermodynamicsUse whenever a microscopic model must be connected to macroscopic thermodynamics — or whenever a thermodynamic quantity is claimed and must be trusted.
• Symmetry and conservation lawsUse whenever you are about to solve, or have just solved, a dynamical system — before choosing coordinates and after writing an answer.
• Waves and oscillationsUse whenever a system oscillates, resonates, or propagates a disturbance — a mass on a spring, a driven damped circuit, coupled pendula, a plucked string, a wave packet.
