Incompatible birth dates
Sources disagree: August 19, 1584 (Encyclopædia Britannica; MacTutor History of Mathematics archive; The Galileo Project; Complete Dictionary of Scientific Biography) or September 8, 1580 (No external source identified).
The main date retains its own sources. These alternatives overlap neither all other statements nor the main date. Rank is Wikidata editorial priority, not proof.
