Hisab-Mimamsa — Theoretical Physics Engine

Hisab (Arabic: حساب — calculation) + Mimamsa (Sanskrit: मीमांसा — critical inquiry)

Computational theoretical physics built on the hisab math foundation. General relativity, quantum field theory, cosmology, and unified field models.

Architecture

Four domain modules, each feature-gated:

• relativity — General & special relativity: spacetime metrics, geodesics, Lorentz transforms, gravitational lensing, black hole thermodynamics
• quantum_field (feature qft) — Quantum field theory: field quantization, propagators, Feynman diagrams, renormalization (extends kana beyond circuits)
• cosmology (feature cosmology) — Friedmann equations, dark energy models, CMB power spectrum, large-scale structure, cosmic expansion history
• unified (feature unified) — Bridge between QFT and GR: effective field theory, holographic principle, information-theoretic bounds, fixed point convergence

bhava Bridge (Scale 3-7)

The unified module provides bridge functions for bhava’s consciousness model:

• Scale 3: Planetary field → personality manifestation (via jyotish)
• Scale 4: Stellar influence → soul motivation layers (via tara)
• Scale 5: Galactic structure → civilizational personality fields
• Scale 6: Cosmic expansion → manifestation intensity scalar
• Scale 7: Cosmic breath phase → unity/differentiation cycle

The fixed point at zero (Unity) emerges from the cosmological model: at heat death / maximum entropy, all fields converge to ground state, all manifestation intensity → 0.0, all bridge outputs → identity element.

Examples

Special relativity — muon time dilation at 0.994c:

use hisab_mimamsa::relativity::lorentz;

let gamma = lorentz::lorentz_factor(0.994 * lorentz::C).unwrap();
assert!((gamma - 9.14).abs() < 0.1);

General relativity — Schwarzschild radius of the Sun:

use hisab_mimamsa::relativity::metric;

let rs = metric::schwarzschild_radius(1.989e30).unwrap();
assert!((rs - 2953.0).abs() < 5.0);

Black hole thermodynamics — Hawking temperature:

use hisab_mimamsa::relativity::black_hole;

let t = black_hole::hawking_temperature(1.989e30).unwrap();
assert!(t > 1e-9 && t < 1e-6);
