Module 3
Quantum Mechanics & The Standard Model
The measurement problem, QED, QCD, and the fermion/boson taxonomy.
This module covers the 20th-century abstractions you need to re-familiarise yourself with before OFT reduces them to continuous field topology. The goal is not to re-learn quantum mechanics — it is to map the territory clearly enough to see what OFT replaces and why.
Concepts to Cover
The Measurement Problem Wave-particle duality, the Copenhagen interpretation, wavefunction collapse, and the Born rule. Why does the wavefunction give probabilities? What happens at measurement? Why has no one agreed on an answer for a century? OFT dissolves this problem entirely — but you need to understand why it was a problem first.
Quantum Electrodynamics (QED) Virtual particles, Feynman diagrams, the running coupling constant, and the infinities that require renormalisation. The extraordinary predictive precision of QED, and the extraordinary ugliness of the procedure that produces it. OFT explains what virtual particles actually are.
Quantum Chromodynamics (QCD) The strong force, colour charge, asymptotic freedom, and the mass gap. Why quarks cannot be isolated. Why the proton is so much heavier than the sum of its quarks. OFT 5 resolves the mass gap from pure topology.
Fermions vs. Bosons Standard definitions, the Pauli exclusion principle, and spin — specifically spin-½. Why does an electron need to rotate 720° to return to its original state? OFT explains this geometrically from the toroidal soliton structure.
Resources
Stanford / Leonard Susskind — Quantum Mechanics (The Theoretical Minimum)
Essential viewing for re-orienting with the measurement problem, states, operators, and the standard taxonomy of bosons and fermions. Susskind is rigorous without being pedantic.

PBS Space Time — Quantum Field Theory, QED, and QCD
Their dedicated playlists on the Standard Model provide deep, visually rich insights into renormalisation, the running coupling constant, asymptotic freedom, and the Yang-Mills mass gap. This maps the exact orthodox terrain you need to understand before transitioning to a topological field view.
