Capabilities

Built for precision.
Designed for intuition.

We combined professional-grade numerical solvers with beautiful real-time rendering. No downloads required.

Interactive Sandbox

Drag and drop physics objects — masses, charges, lenses, wave sources. Build your own experiments with real-time feedback.

Real-Time Data Output

Every simulation generates live graphs, vector overlays, and exportable data tables alongside the 3D visual.

Save & Share Labs

Serialize experiments to JSON. Save to the cloud. Generate shareable links so anyone can load your exact setup.

WebGPU Compute

GPU-accelerated compute shaders for N-body simulations, field solvers, and DFT band structure — all in-browser.

LaTeX-Grade Theory

Every simulation includes governing equations rendered in KaTeX, theoretical context, and guided exercises.

Five Physics Domains

Classical Mechanics, Electromagnetism, Quantum Mechanics, Special Relativity, and Density Functional Theory.

Simulation Library

27 simulations.
Six physics domains.

From projectile motion to quantum tunneling, each simulation features interactive controls and real-time data output.
