Open thread, Tuesday

A nice shot by Lesley from our recent trip to the Mendocino County coast.

Since you're reading this, so you're not vacationing, there are several gigs this week to check out: jazz jam at The Raven Thursday 8-10, the trio at Tlaquepaque Friday afternoon, the quartet featuring Susannah Martin at Ken's Creekside in VOC Friday 9-12, and Big Daddy in front of the PV Harkins on Saturday 5-9. Hope to see you out and about.

Scene from my window: Talking nonstop, holding his cellphone to his left ear, a driver tries to manhandle his street-sweeper with one hand through a U-turn among the parked cars in front of my house, wiping out some edging and narrowly missing my fence, backing up nervously, then sailing back down the street, leaving the usual dirt cloud and muddy trail behind him and missing the gutter completely. Who trains these guys?

And just for fun, a nine-minute instant mind-expansion on what this means to a physicist or mathematician.
