Meet Pi Day founder Larry Shaw, and join hosts Ron Hipschman and Lori Lambertson to find out whats so special about pithe irrational number that results from dividing the circumference of a circle by its diameter. Learn the history of pi and how pi is calculated, be entertained by pi limericks, and see a cool pi demo. Pie. Senior Exploratorium Scientist, Paul Doherty demonstrates how you can make your own sun viewer. You can safely view sunspots, eclipses and transits with this equipment that you may have laying around the house!

Cornucopia and Shelly Valdez share their impressions of the phenomena of light cycles in Chaco Canyon. Astronomer Dr. Isabel Hawkins's journey to the stars began with two chance moments of enchantment with celestial bodies in her native Argentina. Inspired by the mystery of the sky, she went on to study physics and astronomy in California and then to work for 20 years as a research astronomer at UC Berkeley. Now retired from research and devoted to inciting a love of the stars and sky in young people, Dr. Hawkins reflects on her own initial moments of inspiration, on sharing her love of stars with others, and on how astronomy can, and should, remind us of our connection to one another, under a canopy of mystery.
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 While in the field, the Exploratorium Eclipse remote team had a love/hate relationship with the clouds. The cloudscape of the Weizi Gorge was so spectacular it was easy to overlook that our fluffy friends could have potentially blocked our main reason for lugging 1700 lbs. of gear out to the edge of the Gobi Desert-the total solar eclipse! This is a short time-lapse video of the sky at our camp one day before the eclipse. Why do the hands on clocks go "clockwise?" Seems like a circular definition, but if you looked closely at sundials in the northern hemisphere, you'd notice that the shadow of the sun moves around the sundial in a "clockwise" direction. This was adopted by clock-makers and became the standard we know today.
In the southern hemisphere, the sun's shadow moves around the dial in the opposite direction, so if clocks had been invented there, our watches would move the other way. On August 1, 2008, a total solar eclipse occurred as the new moon moved directly between the sun and the earth. The moon's umbral shadow fell on parts of Canada, Greenland, the Arctic Ocean, Russia, Mongolia, and China. The Exploratorium's eclipse expedition team (our fifth!) Webcast the eclipse live from the remote Xinjiang Uygur Autonomous Region in northwestern China near the Mongolian border. The Exploratorium celebrates the 20th anniversary of Pi Day with a pie-throwing contest, Pi Day exhibits in Second Life, and more activities honoring everyone's favorite mathematical constant. 3/14 at 1:59 pm

From San Francisco to New York, in museums, universities, classrooms and in
the privacy of ones own home - and of course on Second Life - people are
celebrating Pi. In 2008, we celebrate the 20th anniversary of Pi Day, an
international holiday born at San Franciscos Exploratorium.
