 ||1979 – A bright flash, resembling the detonation of a nuclear weapon, is observed near the Prince Edward Islands. Its cause is never determined.
+||Charles Ehresmann (d. 22 September 1979) was a French mathematician who worked in differential topology and category theory. He was an early member of the Bourbaki group, and is known for his work on the differential geometry of smooth fiber bundles, notably the Ehresmann connection, the concept of jets of a smooth map, and his seminar on category theory.
