Portuguese inventions — The 'chart of latitudes' is a misleading term; the correct term is 'regimento do astrolábio' (rule of the astrolabe), a navigational table, and its attribution is nuanced.
Portuguese inventions — The 'Carracks black sword' is not a standard historical term; the 'espada preta' (black sword) existed but is not specifically tied to the carrack ship type in historical canon.
Caravel — The entry states the final recorded usage in printed maritime records dates to 1766, which is not part of the established canon; most historical accounts place the caravel's decline in the 16th or early 17th century.
Caravel — The entry says 'The Niña was re-rigged by Columbus with square rig', which is misleading; the re-rigging occurred at the Canary Islands before the first voyage, not during the crossing.
Cerebral angiography — Egas Moniz did not contribute to creating thorotrast; thorotrast was developed by others (e.g., introduced by the Heyden company in 1928) and Moniz used it as a contrast agent, but he did not invent or co-create it.
Cerebral angiography — The entry states Moniz developed cerebral angiography in 1927 at the University of Lisbon; while Moniz was a professor at the University of Lisbon, the first successful cerebral angiogram was performed in 1927 at the Hospital de Santa Marta in Lisbon, not spec
Chip log — The entry states that the Dutchman's log is attributed to Portuguese Bartolomeu Crescêncio, late 15th or early 16th century, but this attribution is not supported by reliable historical sources and appears to be invented or unsupported.
Chip log — The LORE section claims the Dutchman's log is an earlier device than the chip log, yet gives its first reference as 1623, which is later than the chip log's first known print description in 1574, creating a factual inconsistency.
Eslicarbazepine acetate — The entry states as fact that in May 2025 the medication's primary US patents expired and generic versions became available, but as of October 2023 this is a future event that cannot be verified as factual; it should be presented as an anticipated or projected
Via Verde — The claim 'Motorcycles are considered Class 1 for manual toll collection but Class 5 when using Via Verde' is factually incorrect; motorcycles are Class 1 for both.
