- Earlier this year, DeepMind published groundbreaking work on detecting unstable
singularities in fluid dynamics—one of the deepest open problems in mathematical
physics (arXiv:2509.14185).
- The challenge? No public code. - Extreme numerical precision requirements. - Complex multi-stage training. This makes independent verification nearly impossible. - So I built an open-source re-implementation to bridge that gap.

### What It Does
Detects finite-time blow-ups in PDEs using Physics-Informed Neural Networks:
- Lambda prediction formulas (<1% error vs. published methodology) - Automated parameter discovery via funnel inference - High-precision Gauss-Newton optimization (residuals to 10⁻¹³) - Multi-stage training with configurable precision targets
Think: Making century-old fluid dynamics problems tractable with modern ML.

### Who This Is For
- Researchers studying singularities in PDEs - Practitioners working with PINNs - Anyone frustrated by non-reproducible ML papers - Students learning scientific machine learning
---
### Built For Reproducibility
- 119 comprehensive tests (all passing) - GPU-accelerated with PyTorch + CUDA - Automated validation CI/CD - Professional documentation + limitations clearly stated - Not just "research code"—designed to actually work in other people's hands.
---
### Current Implementation Status
- Lambda prediction formulas (formula-based validation) - Funnel inference (secant method) - Enhanced Gauss-Newton optimizer (test problem verified) - PINN solver framework - Multi-stage training (framework complete, full validation pending) - Full 3D Navier-Stokes solver (future work) - Transparency matters: This shows exactly what works today vs. what's roadmap.
