# Episode 04: Observe without remote control

Correlations are not instant messages

## Narration script

The two outcomes are related statistically, but each local result remains random. This panel models a polarization singlet, different from the previous Bell state. The formula uses twice the analyzer-angle difference. When both observers later compare records, the correlation varies with their settings. Alice cannot choose Bob’s result to send an instant signal. Do not animate a controllable influence travelling from one photon to its partner.

## Exact footage

Capture step 4 with A=0 and B=0,45,90. Show the numeric probabilities and graph together. Zoom on each local marginal staying one half.

## Recording steps

1. Use a clean browser profile and 1920×1080 capture; enable a visible cursor.
2. Record the introduction, then the listed demo in one deliberate pass.
3. Pause on each prediction before showing the output; record narration separately if needed.
4. Review captions, mathematical symbols and scientific claims against the sources.
5. Check for private data; export a local draft. Publishing requires a separate decision.

## Acceptance

Explain a joint correlation while preserving random local outcomes.
