Alpha particle → body temperature in four steps
He-4 binding energy × register scaling factor K_bio = 460,800 = body temperature 36.864°C = 2⁹×3²/5³ degrees Celsius. The same alpha particle that powers stellar nucleosynthesis encodes the human thermal set-point.
He-4 B = 800/(9π) MeV = 28.281 MeV (529 ppm from measured)
Key Results
He-4 binding energy B = 800/(9π) MeV = 28.281 MeV. Alternatively B = 5¹⁰/(2⁴×3⁷×π²). Both are {2,3,5,π} lattice nodes.
T_body = He-4 × K_bio = 36.864°C = 2⁹×3²/5³ = 4608/125°C. Pure {2,3,5} rational.
Two π-register positions: normothermia 36.864°C (π⁰) and fever threshold ~37.0°C (π¹ offset). Separation ≈ G-bond step × 36.864°C. Fever = G-bond register crossing.
The same He-4 that drives stellar triple-alpha fusion encodes human body temperature. Stellar and biological Tau-registers are connected by a pure {2,3,5} scaling chain.
