Magnetism
Magnetism is the class of physical attributes that are mediated by a magnetic field, which refers to the capacity to induce attractive and repulsive phenomena in other entities. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomena of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, and nickel and their alloys. The rare-earth metals neodymium and samarium are less common examples. The prefix ' refers to iron because permanent magnetism was first observed in lodestone, a form of natural iron ore called magnetite, Fe3O4. All substances exhibit some type of ...

LZ 127 Graf Zeppelin
LZ 127 ''Graf Zeppelin'' () was a German passenger-carrying, hydrogen-filled rigid airship that flew from 1928 to 1937. It offered the first commercial transatlantic passenger flight service. Named after the German airship pioneer Ferdinand von Zeppelin, a count () in the German nobility, it was conceived and operated by Dr. Hugo Eckener, the chairman of Luftschiffbau Zeppelin. ''Graf Zeppelin'' made 590 flights totalling almost 1.7 million kilometres (over 1 million miles). It was operated by a crew of 36, and could carry 24 passengers. It was the longest and largest airship in the world when it was built. It made the first circumnavigation of the world by airship, and the first nonstop crossing of the Pacific Ocean by air; its range was enhanced by its use of Blau gas as a fuel. It was built using funds raised by public subscription and from the German government, and its operating costs were offset by the sale of special postage stamps to collectors, the support of the ...

North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole. The North Pole is by definition the northernmost point on the Earth, lying antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the North Pole, so any time can be used as the local time. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about away, though some perhaps semi-permanent gravel banks lie slightly clos ...

Italia (airship)
The ''Italia'' was a semi-rigid airship belonging to the Italian Air Force. It was designed by Italian engineer and General Umberto Nobile who flew the dirigible in his second series of flights around the North Pole. The ''Italia'' crashed in 1928, with one confirmed fatality from the crash, one fatality from exposure while awaiting rescue, and six missing crew members who were trapped in the still-airborne envelope. At the end of the rescue operations there were a total of 17 dead (crew and rescuers). Design and specifications ''Italia'' was an N-class semi-rigid airship, designation N-4. It was almost identical in design to the N-1 but slightly larger in gas capacity. * First flight: 1928 * Length: * Diameter: * Gas capacity: * Performance: * Payload: * Power plant: 3 Maybach diesel engines, total Polar expedition At the end of 1927, after much insistence, Nobile gained permission to use this airship for a new scientific expedition to the North Pole under the ae ...

Krasin (1916 Icebreaker)
The first icebreaker ''Krassin'', or ''Krasin'', (russian: Красин) was built for the Imperial Russian Navy as ''Svyatogor''. She had a long, distinguished career in rescue operations, as well as a pathfinder and explorer of the Northern Sea Route. She has been fully restored to operating condition and is now a museum ship in Saint Petersburg. History The icebreaker was built by Armstrong Whitworth in Newcastle upon Tyne under the supervision of Yevgeny Zamyatin. (updates articles by Myers published in ''Slavonic and East European Review'') The vessel was launched as the ''Svyatogor'' on 3 August 1916 and completed in February 1917. Up to the beginning of the 1950s she remained the most powerful icebreaker in the world. During the allied intervention against the Bolsheviks in Northern Russia (1918–19) she was scuttled by Bolshevik forces to block the port at Arkhangelsk. The Royal Navy raised her for use in the White Sea and later brought her to England. She was moved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
