The San Francisco Bay Area Portal
The San Francisco Bay Area (referred to locally as the Bay Area) is a populous region surrounding the San Francisco and San Pablo estuaries in Northern California. The region encompasses the major cities and metropolitan areas of San Jose, San Francisco, and Oakland, along with smaller urban and rural areas. The Bay Area's nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. Home to approximately 7.68 million people, the nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a network of roads, highways, railroads, bridges, tunnels, and commuter rail. The combined statistical area of the region is the second-largest in California (after the Greater Los Angeles area), the fifth-largest in the United States, and the 43rd-largest urban area in the world with 8.80 million people.
The Bay Area has the second-most Fortune 500
companies in the United States, after the New York metropolitan area
, and is known for its natural beauty, liberal
politics, entrepreneurship, and diversity
. The area ranks second in highest density of college graduates, after the Washington, D.C. metropolitan area
and performs above the state median household income in the 2010 census; it includes the five highest California counties by per capita income
and two of the top 25 wealthiest counties in the United States
. Based on a 2013 population report from the California Department of Finance
, the Bay Area is the only region in California where the rate of people migrating in from other areas in the United States is greater than the rate of those leaving the region, led by Alameda and Contra Costa counties. (more...)
The Castro District
commonly referenced as The Castro
, is a neighborhood in Eureka Valley
in San Francisco, California
. The Castro was one of the first gay neighborhoods
in the United States and has been one of the most lively for several decades. Having transformed from a working-class neighborhood through the 1960s and 1970s, the Castro remains one of the most prominent symbols of lesbian
, and transgender
) activism and events.
San Francisco's gay village is mostly concentrated in the business district that is located on Castro Street from Market Street to 19th Street. It extends down Market Street toward Church Street and on both sides of the Castro neighborhood from Church Street to Eureka Street. Although the greater gay community was, and is, concentrated in the Castro, many gay people live in the surrounding residential areas bordered by Corona Heights, the Mission District, Noe Valley, Twin Peaks, and Haight-Ashbury neighborhoods. Some consider it to include Duboce Triangle and Dolores Heights, which both have a strong LGBT presence. (more...)
Emilio Gino Segrè
(30 January 1905 – 22 April 1989) was an Italian physicist
and Nobel laureate
who discovered the elements technetium
, and the antiproton
, a sub-atomic antiparticle
, for which he was awarded the in Nobel Prize in Physics
Born in Tivoli, near Rome, Segrè studied engineering at the University of Rome La Sapienza before taking up physics in 1927. Segrè was appointed assistant professor of physics at the University of Rome in 1932 and worked there until 1936, becoming one of the Via Panisperna boys. From 1936 to 1938 he was Director of the Physics Laboratory at the University of Palermo. After a visit to Ernest O. Lawrence's Berkeley Radiation Laboratory, he was sent a molybdenum strip from the laboratory's cyclotron deflector in 1937 which was emitting anomalous forms of radioactivity. After careful chemical and theoretical analysis, Segrè was able to prove that some of the radiation was being produced by a previously unknown element, dubbed technetium, which was the first artificially synthesized chemical element which does not occur in nature.
