The Exploratorium is a museum in San Francisco whose stated mission is to change the way the world learns. It has been described by the New York Times as the most important science museum to have opened since the mid-20th century, an achievement attributed to "the nature of its exhibits, its wide-ranging influence and its sophisticated teacher training program". Characterized as "a mad scientist's penny arcade, a scientific funhouse, and an experimental laboratory all rolled into one", the participatory nature of its exhibits and its self-identification as a center for informal learning has led to it being cited as the prototype for participatory museums around the world.

The Exploratorium was founded by physicist and educator Frank Oppenheimer and opened in 1969 at the Palace of Fine Arts, its home until January 2, 2013. On April 17, 2013, the Exploratorium reopened at Piers 15 and 17 on San Francisco's Embarcadero. The historic interior and exterior of Pier 15 was renovated extensively prior to the move, and is divided into several galleries mainly separated by content, including the physics of seeing and listening (Light and Sound), Human Behavior, Living Systems, Tinkering (including electricity and magnetism), the Outdoor Gallery, and the Bay Observatory Gallery, which focuses on local environment, weather, and landscape.(more...)

Ronald Vernie "Ron" Dellums (born November 24, 1935) served as Oakland's forty-fifth (and third African-American) mayor. From 1971 to 1998, he was elected to thirteen terms as a Member of the U.S. House of Representatives from Northern California's 9th Congressional District, after which he worked as a lobbyist in Washington D.C..

Dellums was born into a family of labor organizers, and enlisted in the United States Marine Corps before serving on the Berkeley, California, City Council. Dellums was the first African American elected to Congress from Northern California and the first openly Socialist successful non-incumbent Congressional candidate since World War II. His politics earned him a place on President Nixon's enemies list.

During his career in Congress, he fought the MX Missile project and opposed expansion of the B-2 Spirit stealth bomber program. When President Ronald Reagan vetoed Dellums' Comprehensive Anti-Apartheid Act of 1986, a Democratic-controlled House and a Republican-controlled Senate overrode Reagan's veto, the first override of a presidential foreign policy veto in the 20th century.

Bay to Breakers is an annual footrace in San Francisco on the third Sunday of May. The name reflects the fact that the race starts at the The Embarcadero adjacent to San Francisco Bay and finishes at the Great Highway adjacent to Ocean Beach and its "breaking waves". It is well known for many participants wearing costumes, and a few engaging in public nudity. The event was officially the world's largest footrace from 1986 (with 110,000 participants) until it was surpassed in 2010 by City2Surf in Sydney, Australia.
