Add QuantaLab: interactive virtual science laboratory on Cloudflare Python Workers

[Copilot]

Bootstraps the QuantaLab application from scratch — a browser-based virtual lab with real-time Canvas simulations across physics, chemistry, and biology, guided by an AI mentor via Cloudflare Workers AI.

Architecture

• Cloudflare Python Worker (src/index.py) — HTTP router serving the API and delegating static assets via wrangler.toml assets binding
• AI Mentor (src/ai_mentor.py) — calls @cf/meta/llama-3.1-8b-instruct through env.AI.run(); Socratic system prompt, 10-turn history window
• Experiment catalogue (src/experiments.py) — 9 experiments (3 per domain) as typed dicts with parameter ranges, defaults, and learning objectives; JSON-serialisable for the API

API surface

Method	Path	Description
GET	/api/experiments	Full catalogue
GET	/api/experiments/{domain}/{id}	Single experiment
POST	/api/mentor	AI mentor chat
GET	/api/health	Health check

Frontend (static/)

Single-page app — fixed header with domain nav, experiment sidebar, Canvas simulation panel, and AI chat pane. No framework dependencies.

Nine Canvas simulations, each driven by live sliders:

Domain	Experiments
Physics	Pendulum (SHM), Projectile motion, Ohm's Law
Chemistry	Acid–base pH, Boyle's Law (PV), Titration curve
Biology	Mitosis phases, Natural selection, Photosynthesis rate

# Mentor endpoint — POST /api/mentor
body = {"message": "Why does a longer pendulum swing slower?",
        "domain": "physics", "experiment": "pendulum", "history": [...]}

# Worker delegates to Cloudflare AI
reply = await env.AI.run("@cf/meta/llama-3.1-8b-instruct", {"messages": messages})

Tests

22 pytest unit tests covering the experiment catalogue (field presence, parameter range validation, JSON serialisability, uniqueness constraints).

Original prompt

Interactive virtual laboratory where students can explore physics, chemistry, and biology experiments in simulation. Guided by an AI mentor that explains concepts, answers questions, and suggests experiments. Designed to make scientific exploration accessible, safe, and engaging through hands-on digital experimentation. using cloudflare python workers and cloudflare ai
