Reported Tc Timeline

Reported transition temperature versus year, with the date basis, result origin, sample state, pressure, and source retained for each result. Marker colours identify families; symbols identify origins. This is neither a discovery-history chronology nor a world-record leaderboard. Legacy reports are not independently confirmed results.

Reviewed-only mode is unavailable until accepted result-level reviews exist. “Observed only” selects a reported result origin, not experimental confirmation or scientific approval.

Full filtered dataset · before display sampling

19,338 reported results · 8,150 materials · 7,940 linked sources

Sources count distinct bibliographic identifiers, not independent works or independent replications.

Reported Tc range: 0.01 K (10 mK) – 250 K. These are extrema in this filtered dataset, not world-record claims or independently confirmed Tc values.

Temperature view

Markers describe reported result origin, not scientific approval. Catalogue eligibility is governed separately; each hover includes its visibility status. Exact year/Tc overlaps are display clusters only: no results are merged. Click a marker or use the overlap selector below to inspect every received member. Server sampling may omit additional results at the same coordinates; cluster counts refer to this received selection. Years are not jittered.

Inspectable reported results

All 2,000 received results are available here, including coordinate overlaps and results omitted by the SVG renderer budget. This table does not include results omitted by server sampling. Linked sources count bibliographic identifiers, not independent works. An occurrence count is not independent replication; legacy records remain unreviewed.
