The mineral topaz is a silicate of aluminium and fluorine with the chemical formula Al2SiO4(F,OH)2. It crystallizes in the orthorhombic system and its crystals are mostly prismatic terminated by pyramidal and other faces, the basal pinacoid often being present. It has an easy and perfect basal cleavage and so gemstones or other fine specimens should be handled with care to avoid developing cleavage flaws. The fracture is conchoidal to uneven. Topaz has a hardness of 8, a specific gravity of 3.4-3.6, and a vitreous lustre. Pure topaz is transparent but is usually tinted by impurities; typical topaz is wine or straw-yellow. They may also be white, gray, green, blue, or reddish-yellow and transparent or translucent. When heated, yellow topaz often becomes reddish-pink. It can also be irradiated, turning the stone a light and distinctive shade of blue. A recent trend in jewelry is the manufacture of topaz specimens that display iridescent colors, by applying a thin layer of titanium oxide via physical vapor deposition.
Topaz is found associated with the more acid rocks of the granite and rhyolite type and may be found with fluorite and cassiterite. It can be found in the Ural and Ilmen mountains, Czech Republic, Saxony, Norway, Sweden, Japan, Brazil, Mexico, and the United States.
Etymology and historical/mythical usage
The name "topaz" is derived from the Greek topazos, "to seek," which was the name of an island in the Red Sea that was difficult to find and from which a yellow stone (now believed to be a yellowish olivine) was mined in ancient times.

In the 1990s, student activists tended to focus on university and statewide concerns, such as union recognition, the expansion of the Chicano/a Studies Center, Proposition 187, which denied social services to undocumented immigrants, and Proposition 209, which ended affirmative action in California. Campus political debate in the 1980s centered primarily on the South African government's apartheid policies, the U.S.'s Central American policy, as well as the implementation of affirmative action in the state. This demonstration and many others at UC campuses throughout the state caused then-Governor Ronald Reagan to shut down the state's colleges and universities for the first time in California's history.

This report was presented to Congress and was so influential on then-Senator Al Gore that it proved to be the foundation for what would be passed as the High Performance Computing Act of 1991, written and developed by Gore. In 1988, Kleinrock also chaired a group which produced the report Toward a National Research Network. This work proved foundational for their later development of the Transmission Control Protocol - TCP/IP protocol. He would later team with Bob Kahn in the writing of the seminal 1974 paper A Protocol for Packet Network Intercommunication.
Turing Award laureate Vinton Cerf was a doctoral student in the computer science department under Kleinrock in early 1970s and also worked on the ARPANET.

Students are currently guaranteed three years of on-campus housing, but the Housing Master Plan aims to guarantee housing to all undergraduates for four years by 2010. Housing facilities also include four restaurants and three boutique-style eateries. Undergraduate housing for nearly 8,000 residents is spread across 14 complexes on a ridge on the western side of the campus, which is called "the Hill."

Appropriate legislation was signed into law on May 23, 1919 which turned the school into the Southern Branch of the University of California (SBUC) and added its general undergraduate program, the College of Letters and Science. In 1917, Director Ernest Carroll Moore suggested that the State Normal School at Los Angeles should be added as the second campus of the University of California. In 1914, the school moved to a new campus on Vermont Avenue in Hollywood. The new facility included an elementary school where teachers-in-training could practice their teaching technique on real children.
The State Normal School at Los Angeles opened on August 29, 1882, on what is now the site of the Central Library of the Los Angeles Public Library system. In March 1881, after heavy lobbying by Los Angeles residents, the California Legislature authorized the creation of a second State Normal School in downtown Los Angeles to train teachers for the growing population of Southern California. .
