While I'm on the subject of events, I'll be speaking at the University of Pennsylvania School of Design this coming Monday, November 16; I'm giving a talk called The Turbulence Biennial. It's free and open to the public, and it starts at 6pm in Room B1 of Meyerson Hall.

The basic idea will be to revisit and extend some of the material from the climate change/weather control chapter of The BLDGBLOG Book—looking at everything from John Constable and the Cloud Appreciation Society to urban weather-engineering and airplane turbulence as a kind of invisible landscape in the sky.

So if the sky is a geography, how can we both map and design it?

If you're near Philadelphia, definitely come by; I'd love to see you there, and it should be a fun night.
