80th meridian west

The meridian 80° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, North America, the Atlantic Ocean, the Caribbean Sea, Central America, South America, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole.

In Antarctica, the meridian defines the western limit of the British territorial claim and passes through the Chilean claim - the two claims overlap.

The 80th meridian west forms a great circle with the 100th meridian east.

Pittsburgh

Pittsburgh ( PITS-burg) is a city in the Commonwealth of Pennsylvania in the United States, and is the county seat of Allegheny County. As of 2017, a population of 305,704 lives within the city limits, making it the 63rd-largest city in the U.S. The metropolitan population of 2,353,045 is the largest in both the Ohio Valley and Appalachia, the second-largest in Pennsylvania (behind Philadelphia), and the 26th-largest in the U.S.

Pittsburgh is located in the south west of the state, at the confluence of the Allegheny, Monongahela, and Ohio rivers, Pittsburgh is known both as "the Steel City" for its more than 300 steel-related businesses and as the "City of Bridges" for its 446 bridges. The city features 30 skyscrapers, two inclined railways, a pre-revolutionary fortification and the Point State Park at the confluence of the rivers. The city developed as a vital link of the Atlantic coast and Midwest, as the mineral-rich Allegheny Mountains made the area coveted by the French and British empires, Virginians, Whiskey Rebels, and Civil War raiders.Aside from steel, Pittsburgh has led in manufacturing of aluminum, glass, shipbuilding, petroleum, foods, sports, transportation, computing, autos, and electronics. For part of the 20th century, Pittsburgh was behind only New York and Chicago in corporate headquarters employment; it had the most U.S. stockholders per capita. America's 1980s deindustrialization laid off area blue-collar workers and thousands of downtown white-collar workers when the longtime Pittsburgh-based world headquarters moved out. This heritage left the area with renowned museums, medical centers, parks, research centers, and a diverse cultural district.Today, Google, Apple Inc., Bosch, Facebook, Uber, Nokia, Autodesk, Microsoft and IBM are among 1,600 technology firms generating $20.7 billion in annual Pittsburgh payrolls. The area has served as the long-time federal agency headquarters for cyber defense, software engineering, robotics, energy research and the nuclear navy. The area is home to 68 colleges and universities, including research and development leaders Carnegie Mellon University and the University of Pittsburgh. The nation's eighth-largest bank, eight Fortune 500 companies, and six of the top 300 U.S. law firms make their global headquarters in the area, while RAND, BNY Mellon, Nova, FedEx, Bayer and NIOSH have regional bases that helped Pittsburgh become the sixth-best area for U.S. job growth.In 2015, Pittsburgh was listed among the "eleven most livable cities in the world"; The Economist's Global Liveability Ranking placed Pittsburgh as the first- or second-most livable city in the United States in 2005, 2009, 2011, 2012 and 2014. The region is a hub for Leadership in Energy and Environmental Design and energy extraction.In 2019, Pittsburgh was deemed “Food City of the Year” by the San Francisco-based restaurant and hospitality consulting firm af&co. Many restaurants were mentioned favorable, among them were Superior Motors in Braddock, Driftwood Oven in Lawrenceville, Spork in Bloomfield, Fish nor Fowl in Garfield and Bitter Ends Garden & Luncheonette in Bloomfield.

Polar motion

Polar motion of the Earth is the motion of the Earth's rotational axis relative to its crust. This is measured with respect to a reference frame in which the solid Earth is fixed (a so-called Earth-centered, Earth-fixed or ECEF reference frame). This variation is only a few meters.
