Core tier

cpt-core  /  cpt-physics

  • Physical constants (CODATA 2018/2022, container a0 = 1.1169e-10 m/s^2)
  • Stellar astrophysics (Herschel filaments, Bennett pinch, 6 archetypes, Crab pulsar 1.35e18 V)
  • S³ Cosmology (Heegaard solid torus 3.499e80 m^3, Salpeter 45.05 Myr clock, MOTS throats)
  • Nuclear binding engine (Euler edge law 3n_α-6, continuous iron peak A*=59.864, u_nuc)
  • Topology & Higher Hopf fibrations (S⁷→S⁴ Jacobian 16, S¹⁵→S⁸ Jacobian 256, neutrino triad)
  • Particle spectrum & Clifford tension quantum (M_0C = 69.8 MeV)
  • Weber electrodynamics & point-current two-seat Darwin recovery

Pro tier

cpt-pro  /  cpt-physics-pro

  • Vectorized topology APIs
  • Nuclear structure engine
  • Extended precision computational modes
  • Advanced electrodynamics modeling

Featured: V4 Nuclear Engine

Topological nuclear binding energy model

The V4 engine predicts binding energies, decay modes, and drip lines across the entire periodic table with ~1% mean error on total binding energy — SEMF-class accuracy (comparable to the 1935 semi-empirical mass formula). It is calibrated to measured inputs (the α-particle and deuteron binding energies) and uses per-region geometry families; it is a topological phenomenological model, not a zero-parameter first-principles derivation.

Current distribution mode

Core packages are now freely available from the CPT Physics Store. Download as TypeScript (.tgz), Python (.whl / .tar.gz), or as a universal .zip containing both languages with a getting-started guide.

Download Core Packages

Pro packages remain in controlled distribution. Early access is available to qualified collaborators by request. See the Licensing Notice for details.
