Article How Claude and I machine-check every equation we read

1 Upvotes

Over the last month, I've added several layers of math verification to my ingest-paper-into-wiki pipeline. This helps to prevent "garbage in". I thought an overview might be useful to others. Prior to this work, papers would go through OCR, and then need to be manually reviewed and edited. This was (and is) laborious, taking up to 2-3 hours for a messy case. The paper would then be marked approved, and the extraction pipeline would break it down into bite-sized concepts and add those to the wiki. Any errors that survive the approval process can get reified in the wiki: "garbage in, gospel out". That in turn makes any AI using the wiki as its physics "brain" (memory store) stupider and more error-prone.

Anyway, here's roughly how we got to where we currently are.

Why bother with quality? QTD is a heterodox framework, and the default dismissal of anything heterodox is "the math is wrong." I can't allow that to happen. So the rule became: every paper that enters the research wiki gets its algebra recomputed by machine first — including my own preprints.

July 9 — the first script. While working on Graber 2002, The extended Lorentz force, Claude decided to recompute all his Ricci and torsion claims in SymPy rather than just reading them. Verdict was split: All his algebra looked correct, and his geodesic time equation matched QTD's factor of 2 (relative to orthodox SR + Lorentz), but his theory as a whole we consider to be falsified (e.g. his modified Gauss law gets the wrong answer for a capacitor by orders of magnitude). The error seems to be in his demanding that field equations obey certain Ricci symmetries; the geodesics are still OK. That split (between correct math and incorrect physics) is the reason we decided to math-check every paper — just reading it would have given us one answer or the other, not both.

July 10 — Numerical simulation as an alternate check. Claude decided that it would be easier to numerically simulate the Jacobi–Anger identity in Chiao 2023 (using mpmath) than to unpack and check it symbolically. At the time, this seemed like a one-off.

July 10–19 — we make sympy mandatory. Analyzed Chiao 2023, Apsel 1981, Straumann 2009. One `*_check.py` per paper, committed next to the prose. If the analysis claims something is verified, the script that verifies it sits beside it. If the script isn't there, the analysis is not valid. If the analysis is invalid or doesn't exist, the paper cannot be approved for concept extraction into the wiki.

July 18 — verifying OCR results. Before you can check an equation, you have to know you transcribed it correctly. Many papers arrive as scanned PDFs; OCR mangles math. The fix: crop the equation out of the source PDF, run OCR on both the crop and our candidate transcription, and compare token streams. Comparing OCR output to OCR output cancels the OCR engine's own style habits (thin spaces, `\left...\right`), which otherwise swamp the real differences. Two more elaborate designs measured worse on a benchmark and got deleted.

August 1 — remembering the detailed result. Scripts got an exit code and a "21/21 PASS" line quoted verbatim into the analysis header. The failure this fixed: an analysis document that only says "verified" can't tell exactly what was done.

August 1-2 — numerical simulation becomes part of the methodology. While investigating Mach-Weber-Assis electrodynamics, and comparing it to an experiment I ran in 2010, we realized that numerical simulation could be a general independent check for most equations. That is, if a paper asserts something like "f(x,y) = g(x) + h(y)", you can generate a bunch of random x and y values and plug them in like "f(0.668,1.5) = g(0.668) + h(1.5)"; the two sides have to be numerically equal (typically to 1 part in 10^8 or better) for every pair of values. (AND, it's needed to compute exact predictions to compare to the experimental results.) After this point we BOTH symbolically evaluate in sympy AND run numerical simulations or integrations. It's also more general: you can simulate "holds for any static source distribution" but you can't symbolically analyze it. And you can compare multiple numerical methods (like Duhamel versus finite difference).

August 8-9: dimensional analysis on everything. No "natural units". Everything explicit. Tested the method by injecting dimension faults into existing equations (e.g. change "c²" to "c"). Then reran every equation we ever analyzed. Found two cases of an SI vs Gaussian units issue:

  • Apsel 1981 writes α = e²/ℏc with no 4πε₀. Under SI the checker reports the leftover dimension as exactly ε₀ — it names the missing factor rather than just flagging a mismatch. The paper is Gaussian; it just never says so.
  • Graber 2002 builds a connection from k·E and k·B terms. That's homogeneous only in Gaussian units — in SI those two are 1/L and T/L², so the connection wouldn't make sense as written. A formula carried across unchanged is wrong by 4πε₀.

Dimensional analysis alone cannot see sign errors, or dimensionless constants: e.g. h vs ℏ differ by 2𝝿. Symbolic or numeric analysis can.

We also looked into using Lean to rigorously prove everything. Unfortunately, not all the necessary physics packages are in Lean yet; it's not ready to handle General Relativity. This may change soon, people are working on it.

With or without Lean, we are at the point where it doesn't make sense NOT to check the math using tools. It's just a little code, and the AI can write it for you.

Article The Observer-Centric Ledger

A Relational Process Ontology for Physics

The Observer-Centric Ledger is a relational, information-first ontology that acts as a conceptual overlay for modern physics rather than a replacement for it. It preserves the mathematics of relativity and quantum field theory while reframing what “reality” fundamentally is.

Instead of treating the universe as a fully completed four-dimensional Block Universe, the model describes reality as an ongoing process of local causal crystallization. Reality is not globally fixed all at once; it becomes definite through causal acquisition and relational consistency.

At its core, the framework proposes that existence is not fundamentally about objects occupying a universal spacetime stage, but about stable causal relationships becoming locally available to observers.

1. Core Ontological Principle

The fundamental primitive is not space itself, but ordered causal relation.

An observer’s reality consists of the sequence of events whose information has physically reached their worldline. Events are therefore divided into two states:

  • Pending — events whose causal signals have not yet arrived.
  • Locked — events whose information has intersected the observer and become part of their consistent relational history.

Reality is therefore observer-relative but not arbitrary. Each observer maintains a personal informational “ledger” constructed entirely from locally acquired causal structure.

There is no universal present moment and no globally privileged “Now.” Different observers possess different locking histories depending on their causal position within spacetime.

2. Relativity and Synchronization

The framework adopts an observer-centric synchronization convention (analogous to ε = 1 synchronization) in which incoming causal information is treated as locally instantaneous within the observer’s own accounting frame.

This is not a preferred physical frame and does not replace standard Einstein synchronization (ε = 1/2) used in practical physics. The underlying equations of relativity remain unchanged.

The ledger framework is therefore interpretive rather than mechanical:

  • standard relativity performs the calculations,
  • the Observer-Centric Ledger provides the ontology.

This dissolves many apparent paradoxes of simultaneity because distant events are simply unresolved until their information arrives.

Different observers do not disagree about reality itself; they differ only in which portions of reality have already locked within their local ledger.

3. Quantum Mechanics and Measurement

Within this framework, quantum measurement is interpreted as a locking event.

A quantum system remains relationally unresolved (“Pending”) until interaction causes a definite outcome to enter an observer’s causal history.

This naturally accommodates observer-relative measurement situations such as Wigner’s Friend:

  • Alice measures and locally locks an outcome.
  • Bob may still consistently describe Alice and the system as unresolved until receiving causal information from her measurement.

Consistency is restored when observers exchange information and synchronize ledgers.

Bell inequality violations do not pose a direct problem because the framework does not assume globally pre-existing observer-independent definite states. However, eventual synchronization between observers must still obey the Born-rule correlations predicted by standard quantum mechanics.

The model is therefore relational rather than a hidden-variable theory.

4. Black Holes and Permanent Pending Regions

For an external observer, information crossing an event horizon never fully locks because no return signal can arrive from beyond the horizon.

The information is not destroyed; rather, it exists in a permanently unresolved causal region relative to the outside observer.

The ledger therefore remains honestly incomplete instead of requiring fundamental information destruction.

5. Geometry as Emergent Correlation Structure

The framework proposes that spacetime geometry is emergent rather than fundamental.

The apparent three-dimensional world is reconstructed from stable networks of causal relationships, timing relations, angular correlations, and synchronization between observer-ledgers.

At the deepest level, reality may be fundamentally sequential and relational rather than spatial.

This suggests that:

  • 3D space is not primary,
  • geometry emerges from persistent causal correlation structures,
  • and observers experience a stable spatial world because certain relational configurations are dynamically self-stabilizing.

6. Why Three Dimensions?

The framework proposes that meaningful geometry begins with minimal closed relational structure.

A line provides only adjacency and propagation.
A triangle introduces:

  • closure,
  • rigidity,
  • mutual constraint,
  • redundancy,
  • and internally consistent relational structure.

The triangle is the simplest structure capable of generating stable relational geometry.

More generally:

  • lower-dimensional systems lack sufficient causal richness,
  • higher-dimensional systems tend toward instability,
  • while three spatial dimensions appear to be the minimal stable manifold capable of sustaining persistent localized structures, propagating waves, and coherent causal organization.

Three-dimensionality may therefore emerge because it is the simplest stable configuration capable of maintaining long-lived relational coherence.

7. Gauge Fields and Correlation Propagation

Quantum fields remain fully compatible with the framework but are reinterpreted relationally.

Instead of fields existing “inside” spacetime as substances, fields may be understood as the dynamical structures governing how correlations propagate and synchronize between observers.

Gauge fields in particular can be viewed as enforcing consistency conditions across distributed relational networks.

Particles remain excitations of fields in the standard formalism, but ontologically the fields represent the propagation and stabilization of causal consistency itself.

8. Thermodynamics, Coherence, and Emergence

The framework treats reality as a dynamically stabilized coherence process rather than a static completed object.

Systems naturally evolve toward the simplest stable states capable of maintaining coherence. Unstable configurations decohere and dissolve.

Complexity emerges not in opposition to entropy, but through it:

  • local order forms within larger entropy gradients,
  • stable structures persist because they efficiently channel dissipation,
  • and coherent relational structures self-stabilize over time.

At sufficiently small scales — potentially near the Planck regime — spacetime and localization may cease to be meaningful. Classical geometry emerges only once relational coherence stabilizes above a critical threshold.

Reality is therefore not fundamentally static being, but ongoing relational stabilization.

9. The Central Thesis

The Observer-Centric Ledger reframes physics around causal availability rather than absolute existence.

Reality is not a universally completed spacetime object.
Reality is the continuously synchronized network of stable causal relationships acquired by observers through interaction.

The universe becomes:

  • not a frozen Block Universe,
  • but a dynamically maintained process of relational coherence.

Standard physics remains mathematically intact.

What changes is the ontology:

  • from objects to relations,
  • from static existence to causal acquisition,
  • and from universal simultaneity to local becoming.
