The development of recording that took place at the end of the 19th century signified big changes in society. It marked the end of the oral tradition and signaled the beginnings of the information age. Now deep in that age, Seattle's Climax Golden Twins fuse both worlds by creating live, improvised performances that uses the sights and sounds from recordings made during those early days.

Listen with the ears of an auto mechanic to interpret what problems exist in a new interactive exhibit, What's Wrong With This Car? at the Exploratorium in San Francisco. The exhibit, which includes the front half of a new car, encourages visitors to sharpen their listening skills by having them focus on sound as a source of information about an underlying problem, just as a trained mechanic does.

Stanford University's Dr. Stephen Smith, an authority on microscope imaging techniques and the biology of brain cells, will talk about the eye-brain connection in the developing embryo, in the second in the Exploratorium's Cutting Edge Biology Lecture Series. This event, Wiring a Brain to See, is free and open to the public and takes place on Thursday, February 8, 2007 at 7pm in the Exploratorium's McBean Theater.

Liminality: Art on the Threshold, a new exhibition at the Exploratorium, on view from March 8-June 3, 2007, builds on a rich history of boundary-bending projects that play with the Exploratorium's home, the airplane-hangar-like Palace of Fine Arts interior.

Here he tackles the current debate in the United States over intelligent design and looks at its place in science and in the classroom.

This spring at the Exploratorium, children can explore the ways that seeing may or may not be believing at a day of science classes. Families must be Exploratorium members to participate on March 3, 2007 (For Members Only). The class schedule is as follows:

The first collaboration between the Exploratorium and a science research laboratory has resulted in the development of an educational center that is already making waves with students, educators, and scientists. Opened in November 2006, the new Science Education Center at the Laser Interferometer Gravitational-Wave Observatory (LIGO) in Livingston, Louisiana, incorporates the accumulated knowledge of the Exploratorium's decades of experience in developing techniques for the informal learning of science.

Come watch the world's greatest solvers of the Rubik's Cube compete for the fastest times under improbable circumstances. New World Records have been set at the last three Exploratorium-hosted Rubik's Cube events.
