Geographic North Pole - Geographic North Pole The Geographic North Pole, also known as true North, is the northern point at which the Earth's axis of rotation meets the surface. For other definitions of the North Pole, see North Pole. Geographic North has a known fixed position, at latitude 90° North. In whichever direction you travel from here, you are always heading south. The boundaries of Canada extend all the way to the Geographic North Pole. There is no land at this location, which is usually covered by sea ice. The first expedition to the pole is generally accepted to have been made by Navy engineer Robert Edwin Peary, his servant Matthew Henson, and four Inuit men, Ootah, Seegloo, Egingway, and Ooqueah, on April 9, 1909. However, some have estimated that.
Geomagnetic North Pole - Geomagnetic North Pole The Geomagnetic North Pole is the pole of the Earth's geomagnetic field closest to true north. For other places known as the North Pole, see North Pole. Like the Magnetic North Pole, is it a south magnetic pole, because it attracts the north pole of a bar magnet. It is the centre of the region in the magnetosphere in which the Aurora Borealis can be seen. Its present location is 78°30' North, 69° West, near Thule in Greenland. The first voyage to this pole was by David Hempleman-Adams in 1992..
Austro-Hungarian North Pole Expedition - Austro-Hungarian North Pole Expedition This expedition was from 1872-74 and discovered Franz-Josef Land. According to Julius von Payer, one of the leaders, the journey was to find the north-eastern passage. It actually explored the area northwest of Novaya Zemlya. According to the other leader, Karl Weyprecht, the north pole was a secondary target. The financing was an estimated total costs 175,000 florins from Austro-Hungarian nobles. The main ship was the "Tegetthoff," named from an Austrian Admiral under whon Weyprecht served, built by Teklenborg & Beurmann in Bremerhaven. It was a three-masted schooner of 220 tons, 38.34m long, with a 100 hp steam engine..
North Pole - North Pole The North Pole, the northernmost point on the Earth, can be defined in four different ways. Only the first two definitions are commonly used. However it is defined, the North Pole lies in the Arctic Ocean. The Geographic North Pole, also known as True North, is the northernmost point on the Earth as determined by the planet's rotation. It has a known fixed position, at latitude 90° North. The boundaries of Canada extend all the way to the Geographic North Pole. There is no land at this location, which is usually covered by sea ice. The Magnetic North Pole is the northern point at which the geomagnetic field points vertically, i.e. the dip is 90°. This definition was proposed by Sir William Gilbert, a.

Dipole - product of the charge or magnetic strength of one of the poles and the distance separating the two poles. The direction of the dipole moment corresponds to the direction from the negative to the positive charge or from the south to the north pole. (Because of the absence of magnetic monopoles, magnetic dipoles are actually created by current loops or by quantum-mechanical spin.) When placed in an electric (E) or magnetic (B) field, equal but opposite forces arise on each side of the dipole creating a torque Ï„: Ï„ = p × E (Electric dipole moment p) Ï„ = μ × B (Magnetic dipole moment μ) (note: × corresponds to a vector cross product) which will tend to align the dipole with the field. Strictly speaking a dipole contains only two.
Celestial pole - Celestial pole The two celestial poles are the imaginary points where the Earth's spin axis intersects the celestial sphere. The sky appears to drift overhead from east to west, completing a full circuit around the sky in 24 (sideral) hours. This phenomenon is due to the spinning of the Earth on its axis. The Earth's spin axis intersects the celestial sphere at two points. These points are the celestial poles. As the Earth spins, they remain fixed in the sky, and all other points seem to rotate around them. The celestial poles are also the poles of the celestial equatorial coordinate system, meaning they have declinations of +90 degrees and -90 degrees (for the north and south celestial poles, respectively). The north celestial pole currently has nearly.
Totem pole - Totem pole Totem poles are carved from great trees, often cedar, along the Pacific coast of North America. The poles often have lineage crests on them. During the nineteenth century, the great houses had poles in front of them. Many villages also had mortuary poles. The Northwest Coast Native Americans carved poles. Today, poles are being carved and erected up and down the coast. See totem.
True north - True north True north is a navigation term referring to the direction of the North Pole relative to the navigator's position. True north is compared to: Magnetic North Grid north The direction of true north is marked in the skies by the celestial north pole. For most practical purposes, this is the position of Polaris. However, due to the precession of the Earth's axis, true north rotates in an arc that takes approximately 25,000 years to complete. Currently, in 2002, Polaris is at its closest approach to the celestial north pole. 2,000 years ago, the closest star to the celestial north pole was Vega. On maps issued by the United States military, the U.S. Geographical Survey, and the U.S. Navy, true north is marked with a line.
Pole vault - Pole vault Pole vaulting is an athletics event where competitors use a long, flexible pole as an aid to leap over a bar, similar to the high jump, but at much greater heights. High Schooler Chip Heuser clearing a personal best of 5.20 meters at the Texas Relays, April, 2003. "Pole jumping" competitions were known to the ancient Greeks, as well as the Cretans and Celts, but with these exceptions there is no record of its ancient practice as a sport. As a practical means of passing over such natural obstacles as canals and brooks it has been made use of in many parts of the world, for instance in the marshy provinces along the North Sea and the great level of the fens of Cambridgeshire,.
Pole - Pole A magnetic pole is an end point of a magnet. The poles of the Earth, or other planet, are the points where its axis of rotation passes through its surface. See: geographical pole, North Pole, South Pole, polar region. The celestial poles are the ends of the celestial sphere. A pole is a long and straight stick, usually vertical or intended to be used vertically. See barber, pole vault, pole (object). In complex analysis, a pole of a function is a certain simple type of singularity. See pole (complex analysis). A pole is also a unit of length, also called a rod, equal to 5.5 yards or 16.5 feet (5.029 meters in SI units), see pole (length). A Pole is a native of Poland. See.
North - North North is one of the four primary cardinal directions, specifically the direction treated, in Western culture, as the primary direction and used (explicitly or implicitly) to define all other directions. (As to the arbitrary nature of this choice, and psycho-social consequences of it, see boreocentrism.) Table of contents showTocToggle("show","hide") 1 Definitions 2 Magnetic North and Declination 3 Roles of North as Prime Direction 4 Roles of East and West as Inherantly Subsidiary Directions Definitions North can mean: true north, the direction along the earth's surface toward one pole of the earth's rotation, namely the pole that is clearly on one's left when standing at the Equator while facing the rising sun. magnetic north, the direction along the earth's surface in which horizontal magnetic field strength.
North Star - North Star The North Star is that star which is best suited for navigation northwards. A candidate must be visible and circumpolar to the north celestial pole. The North Star has been historically used by explorers to determine their latitude. At any point north of the Equator the angle from the horizon to the North Star (its altitude) is the same as the latitude from which that angle was taken. For example, the angle to the North Star for a person at 30° lattitude will be about 30°. Polaris is the current North Star, but has a visual magnitude of only 1.97. On the other hand, in 3000 BC the faint star Thuban in the constellation Draco was the North Star; and at magnitude 3.67 it.
Kawiti - British in the First Maori War. Descended from Nukutawhiti and Rahiri he was born in the north of New Zealand to the Ngati Hine hapu, one of the subtribes of the Ngapuhi. From his youth he was trained in leadership and warfare. He was present at the Battle of Moremonui when many of the Ngapuhi were slughtered by the Ngati Whatua, then almost twenty years later, in 1825, he was at the Battle of Te Ika a Ranganui when it was the Ngapuhi's turn to slaughter the Ngati Whatua. However he took captive a number of Ngati Whatua and refused to hand them over to Hongi Hika prefering instead to return them to their own people. Kawiti refused to sign the Treaty of Waitangi on 6 February, 1840 seeing that it.
Krypton - atmosphere is about 1 ppm. It can be extracted from liquid air by fractional distillation. Compounds Like the other rare gases krypton is widely considered to be chemically inert. However, studies conducted since the 1960s have uncovered some compoundss of krypton. Krypton difluoride has been made in gram quantities and can be produced in several different ways. Other fluorides and a salt of a krypton called oxyacid have also been found. ArKrKr+ and KrH+ molecule-ions have been investigated and there is evidence for KrXe or KrXe+. Isotopes Naturally occurring krypton is composed of six stable isotopes. Krypton's spectral signature is easily produced with some very sharp lines. Kr-81 is the product of atmospheric reactions with the other naturally occurring isotopes of krypton. It is radioactive with a half-life of 250,000 years..
Venera 15 and 16 - approximately 4 degrees relative to one another. This made it possible to reimage an area if necessary. Each spacecraft was in a nearly polar orbit with a periapsis at 62 N latitude. Together, the two spacecraft imaged the area from the north pole down to about 30 degrees N latitude over the 8 months of mapping operations. In June 1984, Venus was at superior conjunction and passed behind the Sun as seen from Earth. No transmissions were possible, so the orbit of Venera 16 was rotated back 20 degrees at this time to map the areas missed during this period. Venera 15 was launched on June 2 1983, and Venera 16 four days later. Venera 16 reached Venus' orbit on October 14 1983. At one point in time, in 1984, Venus.

James Clark Ross - Parry from 1819 to 1827. In 1831, Ross and his uncle, Sir John Ross, located the North Magnetic Pole as part of a magnetic survey. In 1839 - 1843 James Ross led an Antarctic expedition (1839-43) which charted much of the coastline of the continent. In 1841, he discovered the Ross Sea, Victoria Land and Mount Erebus (a volcano named after one of his ships). The Victoria Barrier later gained the name "Ross Ice Shelf" in his honour. A blue plaque marks Ross's home in Blackheath, London..
