Particles & fields

Everything that has ever existed is made of seventeen things. This is the catalogue.

The companion to Hydrogenic eigenstates. Where Volume I teaches the orbital, Volume II teaches the particles inside it.

A deep-space photograph: thousands of distant galaxies scattered across black sky.
Hubble Ultra Deep Field — every point of light is an entire galaxy. All of it, built from these.

§ Table of contents

  1. i
    The particle table A periodic table for fundamental particles: three generations of fermions, the gauge bosons, the Higgs. Mass, charge, spin, colour at a glance.
    Start here →
  2. ii
    The mass ladder Thirteen orders of magnitude — from the sub-eV neutrino to the 173 GeV top quark — on one log-scale axis. The Standard Model's most uncomfortable plot.
    read →
  3. iii
    Hadron builder Combine quarks. The interface enforces colour neutrality (qq̄ for mesons, RGB for baryons); the rest is bookkeeping. Build π⁺, K⁰, Λ, the proton.
    read →
  4. iv
    Feynman diagrams Compton, β-decay, μ-decay, gluon exchange. Vertices show their coupling constants; the time axis is animatable; the matrix element is printed alongside.
    read →
  5. v
    Fields as particles A scalar field on a line, oscillating. Excite a single Fourier mode and watch it move like a particle. The conceptual leap from QM to QFT, in one canvas.
    read →
  6. vi
    Decay trees Pick something unstable. Watch it cascade — branching ratios, mean lifetimes, generations — until everything that remains is stable.
