OK, back from Ohio. Wonderful trip, everybody very welcoming and helpful,

real Midwestern hospitality. Many, many thanks to all who made it so

enjoyable, especially the math faculties at Denison and Kenyon colleges, and

most especially Mike Westmoreland at Denison. Among many other high points,

I got to ride in Ben Schumacher’s van, which has license plate QUBIT. (This

is a key term of art in the field of quantum computing. Ben coined it –

see here).

I came back with one math joke I hadn’t heard before. Apparently the great

Hungarian algebraic-analyst Alfred Haar had

an elder brother who, though not famous, was a competent mathematician. The

two brothers once co-authored a very important paper jointly with the great

English mathematician G.H. Hardy

This paper is known to history as the Hardy-Haar-Haar paper…..
