Heck, that’s rather surprising! Over sixteen hundred and sixty people have now downloaded the notes on the Galois connection between syntax and semantics which I posted a link to here just a few days ago. Who knows why some pieces really hit the button and others seemingly provoke no interest at all?
(Now, c’mon guys, if you like the Galois piece, your students might just love my intro logic book, which I happened to be checking out today. It would be nice if that book were used some more, having made the effort to write it, as it isn’t at all bad, although I say so myself …)
