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 Middle Ages the name topaz was used to refer to any yellow gemstone, but now the name is only properly applied to the silicate described above.
According to Rebbenu Bachya, the word "Leshem" in the verse Exodus 28:19 means "Topaz" and was the stone on the Ephod representing the tribe of Dan.

The supercomputer, called System X, was disassembled shortly after it was ranked in order for it to be replaced with Apple's rack-based servers which consume both less space and power.
It can be found in the Ural and Ilmen mountains, Czech Republic, Saxony, Norway, Sweden, Japan, Brazil, Mexico, and the United States. The system was made from 1100 dual processor Power Macintosh G5s and cost $5.2 million. Topaz is found associated with the more acid rocks of the granite and rhyolite type and may be found with fluorite and cassiterite.

The Hokies developed a controversial reputation for late-season slides in the early 2000s, rising into the top 5 in October or November four times before losing and falling out of the national championship race. The mineral topaz is a silicate of aluminium and fluorine with the chemical formula Al2SiO4(F,OH)2. Since the 1995 season, the Hokies have finished with a top-10 ranking four times, won four conference championships (three Big East and one ACC), and played once for the national championship, losing to Florida State University 46-29 in the 2000 Sugar Bowl.

Virginia Tech has become a major power in college football in recent years. Webmineral. This rivalry continued until 1970 when VPI's football program became too large and too competitive for VMI.
This rivalry developed into the original "Military Classic of the South," which was an annual football game between VMI and VPI. During the early years of VTCC, a rivalry developed between the Virginia Military Institute and Virginia Tech. Virginia Tech's fight song, which was created in 1919, is Tech Triumph. It remains in use today, although the Old Hokie spirit yell is more widely known. The school's major athletic rivalries include the University of Virginia, West Virginia University, and the University of Miami.
The "athletic VT" symbol is trademarked by the university, and appears frequently on licensed merchandise. The stylized VT (the abbreviation for Virginia Tech) is used primarily by the athletic department as a symbol for Virginia Tech athletic teams. Originally the teams were known as the "Fighting Gobblers" and the turkey motif was retained despite the name change. The mascot is the Hokie Bird, a turkey-like creature.
The word "Hokies" originated in the 1890s; see Hokies for more information. The word "Hokies," which originated from the Old Hokie spirit yell, is often used interchangeably with "Fighting Gobblers" to refer to the sports team, fans, students, or alumni, although the former is the official usage. Its teams participate in the NCAA's Division I-A in the Atlantic Coast Conference, which the school joined in 2004 after leaving the Big East. Virginia Tech's sports teams are called the Hokies; the mascot is the Hokie Bird.
The limestone is mined from various quarries in Southwestern Virginia, Tennessee, and Alabama, one of which has been operated by the university since the 1950s. Each block of Hokie Stone is some combination of gray, brown, black, pink, orange, and maroon. Hokie Stone is a medley of different colored limestone, often including dolomite. On the Blacksburg campus, the majority of the buildings incorporate Hokie Stone as a building material.
The university also has several commonwealth branch campus centers: Hampton Roads (Virginia Beach), National Capital Region (Falls Church- Alexandria, Virginia), Richmond, Roanoke, and the Southwest Virginia Higher Education Center in Abingdon. The Virginia Tech campus is located within Blacksburg; the central campus is roughly bordered by Prices Fork Road to the northwest, Plantation Drive to the west, Main Street to the east, and 460-bypass to the south, though it has several thousand acres beyond the central campus. The College of Agriculture and Life Sciences offers the only two-year associate's degree program on campus, in agricultural technology. Bachelor's, master's, and doctoral programs are offered through the College of Agriculture & Life Sciences, the College of Architecture & Urban Studies, the College of Liberal Arts and Human Sciences, the Pamplin College of Business, the College of Engineering, the College of Natural Resources, the College of Science, and the Virginia-Maryland Regional College of Veterinary Medicine.
From 1970 for the next five years, the student population grew from about 13,500 to 22,000. Similarly, the abbreviation VT is far more common today than VPI or VPI&SU, and appears everywhere from athletic uniforms (most notably on football helmets) to the university's Internet domain vt.edu. In the early 1990s, the school quietly authorized the official use of Virginia Tech as equivalent to the full VPI&SU name; most school documents today use the shorter name, though diplomas still spell out the formal name. The new acronym of VPISU was derisively spoken as Vippy-sue by students and Hahn detractors.
As a compromise, the school added "and State University" to its name in 1970, yielding the current formal name of Virginia Polytechnic Institute and State University. As part of this move, Tech would have taken over control of the state's other land-grant institution, a historically black college in Ettrick, Virginia south of Richmond then called Virginia State College; this failed, and that school eventually became Virginia State University. One of Hahn's more controversial missions was only partially achieved; he had visions of renaming the school from VPI to Virginia State University, reflecting the status it had achieved as a full-fledged public research university. The merger with Radford was dissolved in 1964, and in 1966, the school dropped the two-year Corps requirement for male students (in 1973, women were allowed to join the Corps; Tech was the first school in the nation to open its military wing to women).
Marshall Hahn (1962-74) was responsible for many of the changes that shaped the modern institution of Virginia Tech. President T. Later, throughout the early 20th century, another rivalry developed between Virginia Tech and the University of Virginia (founded 1819). This heartfelt and robust rivalry continued into the late 1970's, when Virginia Tech simply became too large and competitive in its athletic programs for VMI to continue competing (VMI enrolls 1,200 cadets and is the Nation's only all-cadet or classical state military college).
In fact, "The Military Classic of the South" began as a rivalry between VMI and VPI. Shortly after its founding as a Military college, a rivalry began with VPI and Virginia Military Institute (founded 1839). Virginia Tech, for a time, was the largest university in the Commonwealth of Virginia until recently being surpassed by Virginia Commonwealth University and George Mason University. VPI achieved full accreditation in 1923, and the requirement of participation in the Corps of Cadets was dropped from four years to two that same year (for men only; women, when they began enrolling in the 1920s, were never required to join).
The "Agricultural and Mechanical College" section of the name was popularly omitted almost immediately, though the name was not officially changed to Virginia Polytechnic Institute until 1944 as part of a short-lived merger with what is now Radford University. McBryde, the school reorganized its academic programs into a traditional four-year college setup (including the renaming of the mechanics department to engineering); this led to an 1896 name change to Virginia Agricultural and Mechanical College and Polytechnic Institute. Under the 1891-1907 presidency of John M. The school considers this to be its founding date, although some would like to date it to 1851 because the school purchased land and facilities from a private Methodist school on the same site.
Founded under the provisions of the Morrill Act, the institution became a state-supported land grant military institute called the Virginia Agricultural and Mechanical College in 1872. .
Virginia Tech has the largest full-time student population in the Commonwealth of Virginia and is best known for its academic programs in agriculture, engineering, architecture, veterinary medicine, and recently for the success of its football program.
