## Key Features
- Real-time 3D visualization: See a central 2D slice through a 32×32×32 periodic lattice
- Adjustable parameters: Sweep the dimensionless coupling strength (βJ = J/kBT) through the critical point (≈0.22) and tune the external field (βh = h/kBT)
- Monte Carlo updates: Uses the Metropolis algorithm, updating the display every 200 × N³ flip attempts (≈33 million total)
- Live observables: Watch energy and magnetization evolve as you change parameters
## Why this matters The Ising model is a cornerstone of statistical physics and computational science courses. This tool makes it easy to:
- Visualize how temperature and field affect domain formation
- Observe the sharp change in magnetization near Tc
- Experiment with finite-size effects
Try it out and let me know what you think! I’d love feedback on performance, usability, or ideas for new features (e.g., different lattice sizes or algorithms).
