Name of the symbol

Do we have a reliable source for the name 'falsum' for this symbol? Unicode has several characters that look like this, namely the Up tack (U+22A5 ⊥), Perpendicular symbol (27C2 ⟂), and Large up tack (27D8 ⟘).

I suspect that the name 'falsum' is a name for the meaning in logic (after all, it means 'false' in Latin), not for the symbol itself.

I propose to move this page to up tack. macrakis (talk) 14:24, 12 April 2010 (UTC)[reply]

Yes, indeed. Falsum is the name of the logical nullary connective/truth constant, not of the symbol itself.—Emil J. 18:50, 13 September 2010 (UTC)[reply]
