What Happens in Washington, D.C. Stays in Washington, D.C.

I suppose that truer words were never written.

In any event, today I am heading off to Washington, D.C. to principal-investigator workshop that is related to a new NSF grant of mine.

On Thursday, I'll be giving a seminar in the Department of Mathematical Sciences at George Mason University. It will be Mason@Mason — a fixed point!

The first sentence of the abstract of this paper is wonderful!

In case you're wondering, it is from this song

Charles Babbage and "Street Nuisances"

Wow!

One of my fave things about Charles Babbage is he dedicated 28 pages (!!) of his autobiography to street nuisances, in which he classified:

1) Instruments of torture permitted by the govt to be in
daily & nightly use in the streets of London
2) Encouragers of Street Music
