Principia is a multi-agent pipeline built on Gemini that translates natural language into mathematically rigorous, visually stunning numerical simulations. To overcome LLM hallucinations, Principia introduces a "System 2" workflow with a self-correcting loop. First, a Formalizer agent extracts strict math (ODEs, PDEs, SDEs, Quantum mechanics) from user prompts. Then, a Critic peer-reviews it, running dimensional homogeneity cross-checks using SymPy via a Python execution tool. If flawed, the Critic forces the Formalizer to revise using contextual feedback. Once verified, an Execution agent compiles the math into SciPy solvers and Matplotlib rendering scripts. Wrapped in a sleek Next.js UI inspired by Google Antigravity, Principia actively reasons about physics to bring complex concepts to life, paving the way for AI-driven scientific discoveries.
