   Format: MarkdownItextoday a kind soul alerted me by email that the nLab entry _[[synthetic differential geometry]], in linking to "John Bell" inadvertently pointed to the page that refers to the physicist John Stewart Bell (the one with the inequalities), instead of to the mathematician and philosopher _[[John Lane Bell]]_ . I have fixed that now. And I have added warning/disambiguation to both category:people entries.
