Explain the concept of Quantum Entanglement using simple analogies. Analogy: Magic dice that always show the same number when rolled, no matter how far apart they are. Key concepts: Spooky action at a distance, connection, information state. Avoid jargon. Use 'alice' and 'bob' characters.

Optimize Unity game physics for mobile performance. Techniques: 1. Adjust fixed timestep settings. 2. Use primitive colliders over mesh colliders. 3. Implement object pooling for projectiles. 4. Configure collision matrix to reduce checks. 5. Use raycast layers for efficiency. 6. Bake static physics objects. 7. Profile with Unity Profiler and Frame Debugger. 8. Limit rigidbodies on active scenes. Include multi-threading setup for physics calculations.
