Cities may be the defining element of human civilization.
The path from hunter-gatherers in the Paleolithic era 25,000 years ago to the high-tech, high-wonder jumble we inhabit today runs straight through cities. In traveling that path, our construction of cities has always been a dance with physics. In some cases, that physics was explicitly understood; in others, its manifestation was only recognized in hindsight.
As our cities have become more complex the physics embodying their behavior and organization has also become more nuanced, subtle and profound.

From the window of my room at the Courtyard Marriott in downtown Pittsburgh, I can see a sliver of the hotel fitness center. This morning I looked down there and saw a guy with an earpiece. Secret Service.
So I wasn't entirely surprised to walk into the tiny exercise room a little after 7 a.m. and find the Republican vice presidential candidate working out. There was a row of about half a dozen elliptical machines and treadmills, one workout bench, a small rack of dumbbells, an inflatable exercise ball, and a folding workout mat.
An aircraft that had been set to fly Joint Chiefs of Staff Chairman Gen. Martin Dempsey out of Afghanistan today was damaged by shrapnel from rockets fired at the Bagram air field north of Kabul from outside its fences.
Two maintenance workers on the ground were slightly wounded, NPR's Tom Bowman reports. Dempsey was not near the aircraft at the time. He later left Afghanistan on another plane.
