Locomotive
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was f ...

Vacuum Tube
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplification and current rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irving Langmuir
Irving Langmuir (; January 31, 1881 – August 16, 1957) was an American chemist, physicist, and engineer. He was awarded the Nobel Prize in Chemistry in 1932 for his work in surface chemistry. Langmuir's most famous publication is the 1919 article "The Arrangement of Electrons in Atoms and Molecules" in which, building on Gilbert N. Lewis's cubical atom theory and Walther Kossel's chemical bonding theory, he outlined his "concentric theory of atomic structure". Langmuir became embroiled in a priority dispute with Lewis over this work; Langmuir's presentation skills were largely responsible for the popularization of the theory, although the credit for the theory itself belongs mostly to Lewis. While at General Electric from 1909 to 1950, Langmuir advanced several fields of physics and chemistry, inventing the gas-filled incandescent lamp and the hydrogen welding technique. The Langmuir Laboratory for Atmospheric Research near Socorro, New Mexico, was named in his honor, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pupin Hall
Pupin Physics Laboratories , also known as Pupin Hall, is home to the physics and astronomy departments of Columbia University in New York City. The building is located on the south side of 120th Street, just east of Broadway. In 1965, Pupin was named a National Historic Landmark for its association with experiments relating to the splitting of the atom, achieved in connection with the later Manhattan Project. In 2009 the American Physical Society named Pupin Hall a historic site and honored Isidor Isaac Rabi for his work in the field of magnetic resonance. History Pupin Hall was built in 1925–1927 to provide more space for the Physics Department which had originally been housed in Fayerweather Hall. In 1935, it was renamed after Mihajlo Idvorski Pupin (also known as Michael I. Pupin), a Serbian-American scientist and graduate of Columbia. Returning to the university's engineering school as a faculty member, he played a key role in establishing the department of electrical en ...

Interborough Rapid Transit Company
The Interborough Rapid Transit Company (IRT) was the private operator of New York City's original underground subway line that opened in 1904, as well as earlier elevated railways and additional rapid transit lines in New York City. The IRT was purchased by the city in June 1940, along with the younger BMT and IND systems, to form the modern New York City Subway. The former IRT lines (the numbered routes in the current subway system) are now the A Division or IRT Division of the Subway. History The first IRT subway ran between City Hall and 145th Street at Broadway, opening on October 27, 1904. It opened following more than twenty years of public debate on the merits of subways versus the existing elevated rail system and on various proposed routes. Founded on May 6, 1902, by August Belmont, Jr., the IRT's mission was to operate New York City's initial underground rapid transit system after Belmont's and John B. McDonald's Rapid Transit Construction Company was aw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early History Of The IRT Subway
The first regularly operated subway in New York City was opened on October 27, 1904, and was operated by the Interborough Rapid Transit Company (IRT). The early IRT system consisted of a single trunk line below 96th Street in Manhattan, running under Broadway, 42nd Street, Park Avenue, and Lafayette Street. The line had three northern branches in Upper Manhattan and the Bronx, and a southern branch to Brooklyn.

Charles F
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in '' Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its ...
