Remove a source. Watch an uncertainty interval meet a boundary. Inspect what supports the result—and what the experiment cannot establish.
Knowledge carried forward
Pacific wayfinding brings observations of stars, the sun and ocean swells together to navigate at sea. Nainoa Thompson learned from Mau Piailug, a master navigator from Satawal, carrying knowledge between people and generations.
Polynesian Voyaging Society ↗Harrison’s H4 longitude watch, completed in 1759, is one example of navigation advancing through careful instrument making. Its history places measurement and timekeeping alongside the practice of observation.
Royal Museums Greenwich ↗These histories inform the questions we ask. The linked accounts provide cultural and historical context; the source-loss investigation has its own inspectable model and assumptions.
