Reflections: Snow Mirror by Daniel Rozin (Clip)

Running Time:
00:01:59

Snow Mirror is the first in a series of pieces that celebrate slowness and black and white, in this piece the image of the viewer is created by the congregation and accumulation of white snow flakes in areas of the image that are brighter. The result is projected on a transparent silk fabric which creates a feeling of the flakes being suspended in space. Artist Daniel Rozin will be featured in the Exploratorium's 2009 exhibition, Reflections.

Reflections: Shaking Time by Daniel Rozin (Clip)

Running Time:
00:00:40

Shaking Time Mirror is the forth of the "Time Series" Software Mirrors. This series of software mirrors examines notions of time, scanning, motion and stagnation. In Shaking Time Mirror only areas of movement on the screen are refreshed with current video, the rest of the screen ages and turns into a gray stagnant crust. When a viewer moves in front of the piece the crust flakes of and revels the full colored image of the viewer, which gradually grays back. Artist Daniel Rozin will be featured in the Exploratorium's summer exhibition, Reflections.

Reflections: Mirrors Mirror by Daniel Rozin (Clip)

Running Time:
00:01:18

Mirrors Mirror creates the viewers' image by directing 768 small mirror tiles in a way that reflects different portions of their image. The piece is made of 24 columns of "pixels" that form a concaved curved surface that is aimed at the viewer. Brighter pixels reflect the upper body of the viewer and the wall behind him and dark ones are aimed lower. Artist Daniel Rozin will be featured in the Exploratorium's 2009 summer exhibition, Reflections.

The Nobel Prize: 100 Years of Creativity: From Special Relativity to String Theory: How Einstein Turned Physics into (Webcast)

Running Time:
00:48:31

A century after publication of Einstein's famous papers on light and relativity, this most celebrated of Nobel Laureates will be the subject of a talk by award-winning science writer K.C. Cole. She'll discuss the ways in which Einstein continues to influence physics today, from detecting gravity waves to understanding string theory.

Origins: Astrobiology: Life's Ingredients (Webcast)

Running Time:
00:43:30

Julia Child and physicist Philip Morrison once cooked up (and sampled) "primordial soup," a mixture of ingredients said to be the materials from which life sprang on Earth. How accurate is this notion? David Deamer studies how some molecules self-assemble into order, and has developed new theories about how life evolved from components on Earth. We’ll talk with him, do hands-on experiments, and watch vintage footage of Julia Child tasting the soup. Guests: David Deamer, Director, UC Berkeley SETI Program, and Karen Kalumuk, Exploratorium staff scientist.
