[ TRACKS ]

5 TRACKS · AI AGENT · SIMULATION · EDUCATION · RESEARCH · OPEN WILDCARD

Five build tracks

Choose any track. Combine multiple. Use ZEQ in whatever way you find most interesting.

Track 01
AI Physics Agent
Build an AI agent that uses ZEQ for verified physics reasoning. Aerospace AI, drug discovery agent, grid fault predictor — anything where LLM + ZEQ beats LLM alone.
Track 02
Physics Simulation
Interactive simulation powered by real ZEQ operators. Orbital simulator, particle physics visualiser, climate model explorer — live physics on screen.
Track 03
Education Tool
Make physics concepts accessible. Interactive equations, step-by-step operator explanations, ZeqState visualisation — physics education powered by real computation.
Track 04
Research Application
A tool that accelerates scientific research using ZEQ operators. Cross-domain analysis, reproducible computation via zeqond, publishable results. CC BY 4.0 encouraged.
Track 05
Open Wildcard
Build anything that uses ZEQ in a way nobody expected. Game mechanics, financial model, music physics, sports analytics — surprise us. Best surprise wins.
