Independent theoretical & metrological research

Quantized Dimensional Ledger (QDL)

QDL is the minimal representational framework capable of expressing all physical theories within a single dimensional language.

𝒟 = ⟨L, F⟩3+2
Dimensional closure basis

Dimensional closure enforces admissibility across models and domains.

Latest Results

Three executed, reproducible residual-first benchmarks using public data across metrology-relevant domains.

Residual-first benchmarking treats coherent residual structure as the primary model-adequacy diagnostic under declared model families and a stated parameter budget. These records are designed for straightforward external replication. No new physical effects are claimed; the contribution is methodological.

Full benchmark summaries, replication materials, and the broader validation roadmap are on the Experiments page.

Experimental Program

QDL is designed to be testable. The experimental validation roadmap focuses on four complementary tabletop platforms that probe QDL-driven scaling laws in distinct physical regimes.

Validation roadmap
Falsifiable tests of a 3L + 2F ledger

The QDL Experimental Validation Protocol outlines how a conserved Quantized Dimensional Cell could leave measurable signatures in precision experiments. Each platform is designed so that standard theories and QDL give clearly distinguishable scaling behavior.

  • Precision torsion-balance scaling – torque and deflection vs. arm length and mass structure.
  • NV-center frequency-shift measurements – structured offsets in spin resonance under QDL-motivated fields.
  • Cavity-mode length–frequency scaling – resonance structure vs. cavity geometry in the L–F ledger.
  • Metamaterial dispersion-collapse tests – engineered media approximating QDC-like coherence.

Why QDL Matters

A concise view of how the QDL program fits into 21st-century theoretical and experimental physics.

QDL represents a unified dimensional-closure architecture for modern physics. By linking effective field theory structure, gravitation, and dimensional constants through a single conserved cell, it proposes a foundation for physical law that is explicit about its dimensional and metrological commitments.

As manuscripts enter peer-reviewed journals and experimental groups assess the proposed tests, the QDL framework becomes accessible to broader scientific scrutiny. The Institute’s goal is to make every step—from ledger construction to experimental design—transparent, auditable, and falsifiable.
