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. Join artist Alex Warren as he demonstrates the relationship of pigments and binders in the creation of paint. Tsering Wangmo Dhompa is a poet who collects inspiration from the everyday--walking in the city, looking at people, listening to language--as well as from her imagination and memory. In this show we explore her process and product. 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. An homage to the color of passion and pageantry, Red featured special presentations, classic exhibits, and fiery performances by San Francisco’s Theatre Flamenco. Goerte once described architecture as "frozen music," observing their common foundation in mathematics, geometry, and aesthetics. But what is the sound of a skyscraper? A warehouse? A bridge? Here we explore the connections between architecture and music, juxtaposing San Francisco buildings with musical compositions influenced by architecture. This experimental segment of Science in the City asks more questions than it answers.

XTech at the Exploratorium empowers high school students through the practical use of Science, Technology, Engineering, Art, and Mathematics. Students develop skills - designing and building, creating media, and facilitating community education events - that will lead them into college and beyond.
In this show, we will be investigating lasers. Did you know that that LASER was an acronym? It stands for Light Amplification Stimulated by the Emission of Radiation. Join us in learning how a laser works, as well as a real world application for lasers, and finally, how they can create stunning light patterns.
