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
It's also Einstein's Birthday
From San Francisco to New York, in museums, universities, classrooms and in
the privacy of one’s 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 Francisco’s Exploratorium. Join Exploratorium staff Paul Doherty and Robyn Higdon as they discuss the Transit of Mercury. On November 8, 2006, Mercury slowly slid across the face of the sun during a relatively rare event known as a transit. The Exploratorium's Live@ crew was at the Kitt Peak National Observatory in Arizona to cover the event. This webcast includes a brief history of Kitt Peak and its 21 telescopes. On March 29, 2006, a total solar eclipse occurred as the moon moved directly between the earth and the sun. The moon's shadow fell on the earth, first darkening the eastern tip of Brazil, and then moved across the Atlantic Ocean to make landfall in Ghana, Africa. It continued moving northeast through Nigeria, Niger, Libya, Egypt, across the Mediterranean and into Turkey, where an Exploratorium team was waiting. A telescope-only view of the 2006 eclipse, as seen from Turkey. In this zany competition teachers will have ten minutes to create a science activity from a special St. Patrick's Day secret ingredient-things that are green! Celebrate the spring equinox at the Mayan ruins of Chichén Itzá, in the state of Yucatan, Mexico. The alignment of the sun on this day creates the appearance of a shadow, in the form of a serpent, that descends the main staircase of the great pyramid. The Live@Exploratorium crew is there to capture the snake on film and to speak with local archaeologists, archeoastronomers, and solar scientists about this amazing phenomenon. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week's "secret" ingredient - Valentine gifts! Join the Live@ crew and NASA scientists as we delve into the ancient knowledge of the Chacoans, daily sky watchers who amassed a great knowledge about the movements of the sun. And learn why today's astronomers and solar physicists continue to watch the sun, using modern ground-based observatories and orbiting space telescopes.
