# The naming of graphs is a difficult matter

There's an interesting discussion going on at the Secret Blogging Seminar about graph-theoretic terminology. It started out being about what to call a directed graph that is not acyclic, and somehow segued from there into whether the empty graph is connected.

I believe it's a continuation of an discussion from Tea at Berkeley, where a lot of mathematicians have the sort of conversation one would assume mathematicians have when stoned (though I promise most of us are on nothing stronger than tea and cookies at the time).

I assume it must happen often enough, but I don't recall ever seeing a stoned mathematician.

Hang around the town of Berkeley long enough, and you'll see someone from just about any walk of life you can think of stoned eventually.

There used to be (and maybe still is) a regular and well-attended "Green Seminar" at Berkeley, held on the Evans 10th-floor balcony. Or so I'm told.
