What coin would just barely cover the full moon? You may be surprised. TI director (and recovering astrophysicist) Linda Shore explains how our brains distort the actual size of the moon. Composer and performer Pauline Oliveros has been a pioneering figure in American music for over four decades. In this intimate talk recorded at the Exploratorium on February 21, 1985, Oliveros discusses her decision to quit teaching and flee to Italy with her accordion, her appreciation of the Grateful Dead's concert sound system, and the perils of the squeezebox. She also takes audience questions and performs "Rattlesnake Mountain" live. Take a little sound quiz with our host, Stephanie Chasteen, and learn something about how our brains locate sounds.

Despite my better judgment, I invite TI staff educator Eric Muller to do one more set of activities—several things you can do with soda straws.

Video teaser for the upcoming launch of the new Exploratorium website, 'Never Lost'. Learn a little bit about Polynesian Navigation in anticipation of the full website
