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.
Last full accuracy audit: 2026-09-07 · 31 entries checked · 11 flagged · 20 issues confirmed · 11 corrected · 9 still open
Acoustic microscopy — The entry conflates SLAM (Scanning Laser Acoustic Microscope) with SAM (Scanning Acoustic Microscope), which are distinct technologies; the first commercial SAM was not in 1975.
Acoustic microscopy — The entry states Sokolov proposed a device using 3-GHz sound waves in 1936, but historically his proposal was for frequencies up to 3 GHz, not necessarily exactly 3 GHz.
Aluminothermic reaction — The claim that 'the most important application of aluminothermic reactions is the production of ferroalloys' is misleading; historically, the most prominent and widely known application is thermite welding (especially rail track welding), not ferroalloy produc
Aluminothermic reaction — The statement that 'the IEEE recognizes aluminothermic-welded copper cable as the only type of continuous un-spliced cable for grounding applications' is not verifiable as a widely established canon fact; IEEE standards do not exclusively recognize aluminother
ANS synthesizer — The claim 'Only one ANS exists; the original was destroyed and this is an improved version' is incorrect. The original ANS synthesizer was not destroyed; it still exists and is housed at the Glinka Museum of Musical Culture in Moscow.
Anthropometric cosmetology — The claim that Ilizarov discovered in 1965 that bone fragments could be pulled apart and regrown is inaccurate; his discovery of distraction osteogenesis dates to the early 1950s, with first clinical applications in the 1950s, not 1965.
Anthropometric cosmetology — The claim that Ilizarov initially used his apparatus to treat chondrodysplasia is misleading; his early work focused on non-unions, fractures, and congenital deformities, and chondrodysplasia was not his primary initial application.
Bashni — The entry states that Bashni is 'also known as ... rarer Chinese checkers.' This is incorrect: Chinese checkers is a completely different game, not a name for column draughts.
Bashni — The entry says 'When a tower is jumped over, only the uppermost piece is removed from the opponent's column.' This is incorrect for standard Bashni rules: when a tower is jumped, the entire tower is captured, not just the uppermost piece.
Brassicoraphanus — The entry states 'first_published=1825 by Augustin Sageret (as Brassico-raphanus)'. However, Sageret's 1825 work described a hybrid but did not publish the name 'Brassico-raphanus' as a formal genus name; the name 'Brassicoraphanus' was first validly published
Budenovka — The hat was designed by famous Russian painter Viktor Vasnetsov: This is disputed; while Vasnetsov is often credited in popular accounts, the actual designer is unknown or attributed to a commission including artists like Boris Kustodiev and Mikhail Ezuchevsky
Budenovka — Originally called the bogatyrka: The name 'bogatyrka' was a popular nickname, not the official original name; the official name was 'broadcloth helmet' (шлем суконный).
Children's railway — The first children's railway did not open in Moscow's Gorky Park in 1932; it opened in Tbilisi, Georgia on June 24, 1935.
Children's railway — By the time the USSR dissolved in 1991, there were not 52 children's railways operating simultaneously; the peak number of about 52 includes railways that had already closed, so the number operating at dissolution was lower.
