  • BibTeX-friendly PDF management with Zotero

    For years I’ve been jealous of colleagues with Macs who apparently all use BibDesk for managing their article PDF collections and BibTeX citations in one nice program. I think I’ve finally figured out how to do both things on Linux: Zotero, with the Better BibTeX and ZotFile add-ons. Zotero is first of all a citation…

    Proof by legerdemain

    Peli Grietzer shared a blog post by David Auerbach on Twitter yesterday containing the following lovely quote about Smullyan and Carnap: I particularly delighted in playing tricks on the philosopher Rudolf Carnap; he was the perfect audience! (Most scientists and mathematicians are; they are so honest themselves ‘that they have great difficulty in seeing through…

  • Why φ?

    Why φ?

    Yesterday, @gravbeast asked on Twitter, Does anyone know why we traditionally use Greek phi and psi for metasyntactic variables representing arbitrary logic formulas? Is it just because ‘formula’ begins with an ‘f’ sound? And chi was being used for other things? Although Whitehead and Russell already used φ and ψ for propositional functions, the convention…
