Life Sciences & Medicine

From molecule to genome to patient to stride — four apps spanning genomics, pharmacology, clinical medicine, and biomechanics — all at ≤ 0.1% error, all Zeqond-ticked.

This chapter has three sub-sections mapping the scale ladder: Molecular & Genomic (1 app), Pharmacology & Clinical Medicine (2 apps), and Biomechanics (1 app). Every anchor app is live and solves a real problem.

The four anchor apps​

The math — four operators, four scales​

CS43  T(n) = O(n log n)                   (alignment, assembly, phylogeny)
CS47  E(n) = −∑ p log p                   (Shannon entropy of sequence, drug selectivity)
QM12  (iγ^μ ∂_μ − m)ψ = 0                 (Dirac — small-molecule electronic structure)
QM14  n_i = 1/[e^((E−µ)/kT) − 1]          (Bose-Einstein — populated receptor binding)
QM15  n_i = 1/[e^((E−µ)/kT) + 1]          (Fermi-Dirac — saturable transport)
NM19  F = ma                              (joint dynamics)
NM28  L = r × p                           (angular momentum in gait)
NM29  τ = r × F                           (joint torques)

Pharma apps use QM statistics because receptor binding follows a saturable distribution that matches Bose-Einstein/Fermi-Dirac statistics exactly under low-concentration asymptotics. Biomechanics is classical rigid-body. Genomics is information-theoretic.

Runnable worked example — one-compartment IV bolus PK​

Patient weight 70 kg, dose 500 mg IV bolus, volume of distribution V_d = 0.3 L/kg = 21 L, half-life t_{1/2} = 4 h. Closed-form C(t) = (500 / 21) · e^(−0.693 t / 4). At t = 1 h, C = 20.05 mg/L.
