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.

The Loma Prieta earthquake also known as the Quake of '89 and the World Series Earthquake, struck the San Francisco Bay Area of California on Tuesday, October 17, 1989, at 5:04 pm local time. Caused by a slip along the San Andreas Fault, the quake lasted 10–15 seconds and measured 6.9 on both the moment magnitude scale and on the Richter magnitude scale. The quake killed 63 people throughout Northern California, injured 3,757 and left some 3,000–12,000 people homeless.

The earthquake occurred during the warm-up practice for the third game of the 1989 World Series, featuring both of the Bay Area's Major League Baseball teams, the Oakland Athletics and the San Francisco Giants. Because of game-related sports coverage, this was the first major earthquake in the United States to have its initial jolt broadcast live on television. (more...)

Selected biography

Edward Teller (Hungarian: Teller Ede; January 15, 1908 – September 9, 2003) was a Hungarian-born American theoretical physicist who, although he claimed he did not care for the title, is known colloquially as "the father of the hydrogen bomb". He made numerous contributions to nuclear and molecular physics, spectroscopy (in particular, the Jahn–Teller and Renner–Teller effects) and surface physics. His extension of Enrico Fermi's theory of beta decay, in the form of the so-called Gamow–Teller transitions, provided an important stepping stone in its application, while the Jahn–Teller effect and the Brunauer–Emmett–Teller (BET) theory have retained their original formulation and are still mainstays in physics and chemistry. Teller also made contributions to Thomas–Fermi theory, the precursor of density functional theory, a standard modern tool in the quantum mechanical treatment of complex molecules. In 1953, along with Nicholas Metropolis and Marshall Rosenbluth, Teller co-authored a paper which is a standard starting point for the applications of the Monte Carlo method to statistical mechanics.

Teller emigrated to the United States in the 1930s, and was an early member of the Manhattan Project charged with developing the first atomic bombs. During this time he made a serious push to develop the first fusion-based weapons as well, but these were deferred until after World War II. After his controversial testimony in the security clearance hearing of his former Los Alamos colleague J. Robert Oppenheimer, Teller was ostracized by much of the scientific community. He continued to find support from the U.S. government and military research establishment, particularly for his advocacy for nuclear energy development, a strong nuclear arsenal, and a vigorous nuclear testing program. He was a co-founder of Lawrence Livermore National Laboratory (LLNL), and was both its director and associate director for many years. (more...)

Selected city

Milpitas /mɪlˈptəs/ is a city in Santa Clara County, California. It is located with San Jose to its south and Fremont to its north, at the eastern end of State Route 237 and generally between Interstates 680 and 880 which run roughly north/south through the city. With Alameda County bordering directly on the north, Milpitas sits in the extreme northeast section of the South Bay, bordering the East Bay and Fremont. Milpitas is also located within the Silicon Valley. The corporate headquarters of Maxtor, LSI Corporation, Flextronics, Adaptec, Intersil, FireEye, Cisco Systems, JDSU, KLA-Tencor, and SanDisk sit within the industrial zones of Milpitas. The population was 66,790 at the 2010 census. (more...)
