Erie, Pennsylvania

Erie /ˈɪəri/ is a city located in northwestern Pennsylvania, United States. Named for the lake and the Native American tribe that resided along its southern shore, Erie is the state's fourth-largest city (after Philadelphia, Pittsburgh and Allentown), with a population of 102,000. It was the third-largest city in the state until 1999. It is the 2nd largest city in Western Pennsylvania (after Pittsburgh). Erie's Metropolitan Area consists of approximately 280,000 residents and an Urbanized Area population of approximately 195,000. The city is the seat of government for Erie County and the principal city of the Erie, PA Metropolitan Statistical Area.

Erie is near Buffalo, New York, Cleveland, Ohio, and Pittsburgh, Pennsylvania. Once teeming with heavy industry, Erie's manufacturing sector remains prominent in the local economy, though service industries, healthcare, higher education, and tourism are emerging as greater economic drivers. Millions visit Erie for recreation at Presque Isle State Park, as well as attractions like the casino and horse racetrack named for the state park.

Newport (PATH station)

Newport (formerly known as Pavonia – Newport, Pavonia, or Erie) is a PATH station located on Town Square Place (formerly Pavonia Avenue) at the corner of Washington Boulevard in Newport, Jersey City, New Jersey.

History

The station was opened on August 2, 1909 as part of the Hudson and Manhattan Railroad (H&M), originally constructed to connect to the Erie Railroad's Pavonia Terminal. The capitals of the station's columns are adorned with the "E", and recall its original name, Erie. After the Port Authority of New York and New Jersey 1960s takeover of the system, the station was renamed Pavonia, or Pavonia Avenue, itself named for the 17th New Netherland settlement of Pavonia. In 1988, the station became known as Pavonia/Newport to reflect the re-development of the former railyards along the banks of the Hudson River to residential, retail, and recreational uses as Newport. In 2010, the name became Newport.

Union Station (Erie, Pennsylvania)

Union Station is an Amtrak railroad station and mixed-use commercial building in downtown Erie in the U.S. state of Pennsylvania. The Lake Shore Limited provides passenger service between Chicago, New York City, and Boston—Erie is the train's only stop in Pennsylvania. The station's ground floor has been redeveloped into commercial spaces, including The Brewerie at Union Station, a brewpub. The building itself is privately owned by the global logistics and freight management company Logistics Plus and serves as its headquarters.

The first railroad station in Erie was established in 1851 but was replaced with the Romanesque Revival-style Union Depot in 1866. Through a series of mergers and acquisitions by competing railroad companies, which started not long after the establishment of Erie's first railroads, Union Depot became jointly owned and operated by the New York Central and Pennsylvania railroads. To meet the changing needs of the rapidly growing city, planners designed a more modern structure to replace the original depot. The new Art Deco Union Station, dedicated on December 3, 1927, was the first railroad station of that style in the United States.

Siméon Denis Poisson

Siméon Denis Poisson (French: [si.me.ɔ̃ də.ni pwa.sɔ̃]; 21 June 1781 – 25 April 1840), was a French mathematician, geometer, and physicist. He obtained many important results, but within the elite Académie des Sciences he also was the final leading opponent of the wave theory of light and was proven wrong on that matter by Augustin-Jean Fresnel.

Biography

Poisson was born in Pithiviers, Loiret, the son of soldier Siméon Poisson.

In 1798, he entered the École Polytechnique in Paris as first in his year, and immediately began to attract the notice of the professors of the school, who left him free to make his own decisions as to what he would study. In 1800, less than two years after his entry, he published two memoirs, one on Étienne Bézout's method of elimination, the other on the number of integrals of a finite difference equation. The latter was examined by Sylvestre-François Lacroix and Adrien-Marie Legendre, who recommended that it should be published in the Recueil des savants étrangers, an unprecedented honour for a youth of eighteen. This success at once procured entry for Poisson into scientific circles. Joseph Louis Lagrange, whose lectures on the theory of functions he attended at the École Polytechnique, recognized his talent early on, and became his friend (the Mathematics Genealogy Project lists Lagrange as his advisor, but this may be an approximation); while Pierre-Simon Laplace, in whose footsteps Poisson followed, regarded him almost as his son. The rest of his career, till his death in Sceaux near Paris, was nearly occupied by the composition and publication of his many works and in fulfilling the duties of the numerous educational positions to which he was successively appointed.

Poisson (crater)

Poisson is a lunar crater that is located in the southern highlands of the Moon's near side. It lies to the east of the crater Aliacensis and northwest of Gemma Frisius. To the northwest of Poisson is Apianus.

This heavily eroded crater shares a common floor with the satellite crater Poisson T to the west-southwest, and the two craters have more or less merged into a single formation with a narrower neck in between. The rim of Poisson is heavily eroded, and is overlain by several craters. Poisson U is intruding into the southern rim at the junction of Poisson and Poisson T. A low-walled formation is joined to the northern rim at the opposite side of the neck from Poisson U.

The interior floor of Poisson and Poisson T has been resurfaced by basaltic lava, leaving a level surface within the inner walls. A pair of old, worn craters lies along the inner wall in the southeast part of the crater.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Poisson.
