Science in the City: Synesthesia: The Smell of a Sound, The Taste of a Color (Clip)

Running Time:
00:05:30

Monday is spiky. The number nine is orange. The letter F smells like smoke. Roughly one percent of people experience such blending of the senses, known as synesthesia. In this episode we meet Bryan Alvarez, a doctoral candidate at the University of California at Berkeley, who is researching the neural mechanisms of synesthesia in an effort to explain why only some of us experience this cognitive crosstalk.

Science in the City: Lost and Found (Clip)

Running Time:
00:04:58

Obsidian points, Spanish terra-cotta tiles, Prohibition-era liquor bottles—history lies buried underfoot in the Presidio, one of the earliest settlements in San Francisco, occupied in turn by the Ohlone Indians, Spanish, Mexicans, and the U.S. Army. Archaeologist Kari Jones shares tales of recent digs and discoveries in this national park, and explains why most artifacts are dug up only to be reburied.

Exploratorium at the Piers: Exploratorium at the Piers: The Observatory Takes Shape (Clip)

Running Time:
00:07:05

Framing of the Exploratorium's Observatory Building, the only completely new construction at at the piers, began in April 2011. Iron workers placed various sizes of steel beams in piles around the concrete base of the Observatory. Then, while a crane raised and held each beam aloft, the workers used metal spikes to line up the holes of the beams and inserted bolts, tightening them down to tie the structure together. Because the Observatory Building is less than two stories tall, the iron workers were allowed to shimmy across the beams without harnesses. Once this process was finished, the beams were plumbed and welded together.
