We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Emile Berliner — The entry states Berliner completed an apprenticeship to become a merchant before migrating, but established biographies indicate he worked as a clerk and studied, not that he completed a formal merchant apprenticeship.
Emile Berliner — The entry states Berliner founded the Gyro Motor Company in 1909 to develop helicopter technologies, but the company was focused on developing rotary engines for aviation, not specifically helicopter technologies.
Guanahani — The entry states that Guanahaní means 'small upper waters land' in the Lucayan language, but the widely accepted meaning is 'small land above water' or 'small upper land.'
Guanahani — The entry says Columbus wrote the letter to Luis de Santangel in the spring of 1493, but the letter is dated February 15, 1493, and was likely written shortly after that, not specifically in the spring.
Controversy over the discovery of Haumea — The Caltech team first imaged Haumea on May 6, 2004, from Palomar Observatory, but the entry conflates the discovery image taken at Palomar with the SMARTS telescope at Cerro Tololo.
Controversy over the discovery of Haumea — The 'DID YOU KNOW' section says Eris was the first IAU-recognized dwarf planet discovered since Pluto in 1930, which is misleading because Ceres was discovered in 1801 and later reclassified as a dwarf planet; the phrasing is factually incorrect.
Incandescent light bulb — The LORE section states that Marcellin Jobard's 1838 incandescent light bulb used a carbon filament in air, but it actually used a carbon filament in a vacuum.
