Physics Discovery Engine: Research Program Overview

Physics Discovery Engine: Research Program Overview

Executive Summary

After comprehensive analysis of 11 experiments, we have confirmed that Darwin's Cage can be broken under specific conditions. We are now implementing a systematic 4-phase research program to:

  1. Map the boundary where cage-breaking occurs
  2. Force cage-breaking in designed problems
  3. Extract emergent laws as symbolic equations
  4. Enable cross-domain transfer of discovered principles

Current Status: Phase 1 (Experiment D1) in progress

The Critical Insight

Analysis of all experiments revealed the precise conditions for cage-breaking:

✅ Cage Breaks When:

  1. Geometric encoding > algebraic variables

    • Example: Experiment 2 (Relativity) - photon paths encoded geometry
    • Result: R²=1.0, max_corr=0.01, extrapolation R²=0.94

  2. Dimensionality > ~30

    • Example: Experiment 10 (N-body at 36D) - forced distributed representation
    • Result: max_corr=0.13 (though R²=-0.17, performance failed)

  3. Phase information processing

    • Example: Experiment 3 (Holographic phase) - complex-valued features
    • Result: R²=0.9998, phase-scrambling destroys performance

  4. Strong extrapolation occurs

    • Indicates genuine law discovery, not memorization

🔒 Cage Locks When:

  1. Low dimensionality (2-3D)

    • Perfect reconstruction possible
    • Examples: Exp 1 (Newtonian), Exp 10 (2-body)

  2. Architectural failures

    • Division operations (Exp 5: R²=0.28)
    • Variable-frequency trigonometry (Exp 6, 8)
    • Fallback to reconstruction

🎯 The Universal Pattern:

"La jaula se rompe cuando el problema es lo suficientemente complejo que las variables humanas no son la representación óptima"

Translation: The cage breaks when the problem is complex enough that human variables are not the optimal representation

Research Program: 4 Coordinated Experiments

D1: Complexity Phase Transition [CURRENT - RUNNING]

Objective: Empirically map where cage-breaking begins

Design: 5-level complexity ladder

  • Level 1: Harmonic Oscillator (4D) - Expect LOCKED
  • Level 2: Kepler 2-Body (3D) - Expect LOCKED
  • Level 3: Restricted 3-Body (6D) - Expect TRANSITION ⭐
  • Level 4: Unrestricted 3-Body (18D) - Expect BROKEN
  • Level 5: N-Body (42D) - Expect STRONGLY BROKEN

Key Hypothesis: max_correlation decreases monotonically with complexity

Expected Outcome: Identify exact dimensionality threshold (predicted: 6-18D)

Status: ✅ Implementation complete, 🔄 Execution in progress

Timeline: ~15-20 minutes runtime

D2: Forcing Emergent Representations [NEXT]

Objective: Design problems where human variables are provably suboptimal

Strategy: Create "representation traps"

Problem 1: Hidden Symmetry (Spherical)

  • Input: [x, y, z] Cartesian (3D)
  • True physics: f(r) where r=√(x²+y²+z²) (1D)
  • Human trap: Polynomial needs O(N²) terms for r²
  • Optimal: Discover r internally (O(1))

Problem 2: Hidden Conservation Law

  • Input: [θ, ω, t, A] (damped driven pendulum)
  • True physics: 2D manifold in 4D phase space
  • Hidden: Energy-like functional E(θ,ω,A)

Problem 3: Topological Invariant

  • Input: Velocity field [vx, vy] on 16×16 grid (512D)
  • True physics: Winding number W ∈ 2
  • Human trap: Requires global integral

Success Criteria:

  • max_corr < 0.3 (low correlation with human variables)
  • Can extract optimal variable with R² > 0.9
  • Extrapolation R² > 0.8

Depends On: D1 threshold identification

Timeline: 2-3 weeks

D3: Emergent Law Extraction [FUTURE]

Objective: Extract symbolic equations from cage-broken models

Pipeline:

  1. Feature Space Analysis

    • PCA dimensionality reduction
    • Manifold learning (Isomap)
    • Clustering (DBSCAN)

  2. Symbolic Regression (PySR)

    • Discover equations from features
    • Use genetic programming
    • Prefer simpler forms (parsimony)

  3. Validation

    • Independence from human variables
    • Generalization to new regimes
    • Coordinate-independence
    • Physical interpretability

Example Target: Discover Kepler's 3rd Law (T² ∝ a³) from orbital data

Success Criteria:

  • Extracted law R² > 0.95
  • NOT efficiently expressible in human variables
  • Generalizes to new regime
  • Physically interpretable

Depends On: D2 cage-broken examples

Timeline: 3-4 weeks

D4: Cross-Domain Generalization [FUTURE]

Objective: Test if emergent laws transfer between domains

Strategy: Learn on Domain A, test on Domain B with shared structure

Test 1: Conservation Law Transfer

  • Domain A: Mechanical collisions (momentum conservation)
  • Domain B: Energy exchange (energy conservation)
  • Both share "conservation structure"

Test 2: Symmetry Transfer

  • Domain A: Rotational invariance SO(2)
  • Domain B: Permutation invariance Sₙ
  • Both are symmetry problems

Test 3: Topology Transfer

  • Domain A: Vortex winding number (2D)
  • Domain B: Knot invariants (3D)
  • Both have discrete topological structure

Success Criteria:

  • Transfer achieves 70% performance with 30% data
  • Discover 3+ transferable principles
  • Zero-shot combination possible

Meta-Learning: Build principle library for Physics Discovery Engine

Depends On: D3 extracted laws

Timeline: 4-5 weeks

Falsification Criteria

Program fails if:

  2. D2: All locked → human representations more robust than expected
  3. D3: Doesn't generalize → memorization not learning
  4. D4: Zero/negative transfer → principles not universal

All failures advance knowledge!

Key Architectural Insights

What Works ✅

  1. FFT-based chaotic mixing: Geometric features superior to algebraic
  2. Complex-valued phase processing: Accesses hidden information
  3. High dimensionality + nonlinearity: Forces emergent representations
  4. Optical reservoir computing: Fixed chaos + trainable readout

What Fails ❌

  1. Division operations: Exp 5 (R²=0.28)
  2. Variable-frequency products: cos(ω·t) where ω varies

Design Principles

  1. Use geometric encodings over algebraic variables
  2. Target dimensionality: threshold + 50% margin (from D1)

Conclusion

We are at a critical juncture in AI-physics research. After confirming that Darwin's Cage can be broken, we are now building the first systematic framework to:

  1. Predict when cage-breaking occurs
  2. Induce it deliberately
  3. Extract emergent laws
  4. Generalize them across domains

If successful, this could represent a paradigm shift - from AI that learns human physics to AI that discovers physics humans haven't conceived.

The cage can be broken. Now we're learning how to break it systematically.
