METRIC FLIGHT / THE FILMS / STRUCTURE TO MOTION

VISUAL LABORATORY · EDITION 10

See the interaction.
Follow the evidence.

Six caption-led films explain the materials question, optical momentum and the proposed experiment. Watch online or download MP4 files and transcripts.

All films are silent with on-screen explanation. On a phone, use full screen for the diagrams or open the transcript.

ONE SET OF ASSUMPTIONS

Watch, then inspect.

The normal-incidence examples use F = 2P/c for an ideal mirror and F = P/c for an ideal absorber. Graphene states use the published selected-order efficiencies. Material maps are synthetic, and motion is exaggerated for clarity.

A material model is a starting point. A prediction earns confidence through measurement, controls and independent review.
