A Subway Named Mobius
"A Subway Named Mobius" is a 1950 science fiction short story by American astronomer Armin Joseph Deutsch. It imagines the results of increasing the complexity of the Boston MTA system (now the MBTA) with a new interconnection. It has been collected in anthologies since its original publication, and was nominated for a Retro Hugo Award in 2001, placing fourth in the final vote. Plot Shortly after the opening of a new track known as the Boylston Shuttle, Boston MTA train No. 86 goes missing. Whyte, the manager of the system, cannot explain its disappearance nor account for the fact that the system acts as though it was still there, drawing power and causing signals to operate automatically, sometimes miles apart. It falls to mathematician Professor Roger Tupelo of Harvard to attempt an explanation. Though not a topologist himself, he believes that the new shuttle connection caused the topological complexity of the system to increase to the point where the connectivity became in ...

Science Fiction
Science fiction (sometimes shortened to Sci-Fi or SF) is a genre of speculative fiction which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, extraterrestrial life, sentient artificial intelligence, cybernetics, certain forms of immortality (like mind uploading), and the singularity. Science fiction predicted several existing inventions, such as the atomic bomb, robots, and borazon, whose names entirely match their fictional predecessors. In addition, science fiction might serve as an outlet to facilitate future scientific and technological innovations. Science fiction can trace its roots to ancient mythology. It is also related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers. Science fiction, in literature, film, television, and other media, has beco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Möbius Strip
In mathematics, a Möbius strip, Möbius band, or Möbius loop is a surface that can be formed by attaching the ends of a strip of paper together with a half-twist. As a mathematical object, it was discovered by Johann Benedict Listing and August Ferdinand Möbius in 1858, but it had already appeared in Roman mosaics from the third century CE. The Möbius strip is a non-orientable surface, meaning that within it one cannot consistently distinguish clockwise from counterclockwise turns. Every non-orientable surface contains a Möbius strip. As an abstract topological space, the Möbius strip can be embedded into three-dimensional Euclidean space in many different ways: a clockwise half-twist is different from a counterclockwise half-twist, and it can also be embedded with odd numbers of twists greater than one, or with a knotted centerline. Any two embeddings with the same knot for the centerline and the same number and direction of twists are topologically equivalent. All of t ...

Massachusetts Bay Transportation Authority
The Massachusetts Bay Transportation Authority (abbreviated MBTA and known colloquially as "the T") is the public agency responsible for operating most public transportation services in Greater Boston, Massachusetts. The MBTA transit network includes the MBTA subway with three metro lines (the Blue, Orange, and Red lines), two light rail lines (the Green and Ashmont–Mattapan lines), and a five-line bus rapid transit system (the Silver Line); MBTA bus local and express service; the twelve-line MBTA Commuter Rail system, and several ferry routes. In , the system had a ridership of , or about per weekday as of , of which the rapid transit lines averaged and the light rail lines , making it the fourth-busiest rapid transit system and the third-busiest light rail system in the United States. As of , average weekday ridership of the commuter rail system was , making it the sixth-busiest commuter rail system in the U.S. The MBTA is the successor of several previous public a ...

1950 Short Stories
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Buenos Aires
Buenos Aires ( or ; ), officially the Autonomous City of Buenos Aires ( es, link=no, Ciudad Autónoma de Buenos Aires), is the capital and primate city of Argentina. The city is located on the western shore of the Río de la Plata, on South America's southeastern coast. "Buenos Aires" can be translated as "fair winds" or "good airs", but the former was the meaning intended by the founders in the 16th century, by the use of the original name "Real de Nuestra Señora Santa María del Buen Ayre", named after the Madonna of Bonaria in Sardinia, Italy. Buenos Aires is classified as an alpha global city, according to the Globalization and World Cities Research Network (GaWC) 2020 ranking. The city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include t ...

Klein Bottle
In topology, a branch of mathematics, the Klein bottle () is an example of a non-orientable surface; it is a two-dimensional manifold against which a system for determining a normal vector cannot be consistently defined. Informally, it is a one-sided surface which, if traveled upon, could be followed back to the point of origin while flipping the traveler upside down. Other related non-orientable objects include the Möbius strip and the real projective plane. While a Möbius strip is a surface with boundary, a Klein bottle has no boundary. For comparison, a sphere is an orientable surface with no boundary. The concept of a Klein bottle was first described in 1882 by the German mathematician Felix Klein. Construction The following square is a fundamental polygon of the Klein bottle. The idea is to 'glue' together the corresponding red and blue edges with the arrows matching, as in the diagrams below. Note that this is an "abstract" gluing in the sense that trying to realize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Argosy (UK Magazine)
''Argosy'' magazine (also known as ''The Argosy'') was the title of three magazines published in the United Kingdom, one in the late 19th century, another in the middle of the 20th century, and the other, very briefly, in the early 21st century. 1865 The original ''Argosy'' was founded and edited by Alexander Strahan in 1865, and later owned and edited by Ellen Wood. A somewhat racy tone was set from the outset by serializing Charles Reade's novel ''Griffith Gaunt'', which concerns a case of bigamy. Among the many well-known contributors were Hesba Stretton, Julia Kavanagh, Christina Rossetti, Sarah Doudney, Rosa Nouchette Carey, Anthony Trollope, Henrietta Keddie (as Sarah Tytler), Helen Zimmern, and the traveller and linguist Arminius Vambery. Wood continued as its editor until her death in 1887, when her son Charles Wood took over. It ran until 1901. 1926 A later British ''Argosy'' was a short story magazine in paperback size focusing on reprints, and was published from 19 ...

Astounding Science Fiction
''Analog Science Fiction and Fact'' is an American science fiction magazine published under various titles since 1930. Originally titled ''Astounding Stories of Super-Science'', the first issue was dated January 1930, published by William Clayton, and edited by Harry Bates. Clayton went bankrupt in 1933 and the magazine was sold to Street & Smith. The new editor was F. Orlin Tremaine, who soon made ''Astounding'' the leading magazine in the nascent pulp science fiction field, publishing well-regarded stories such as Jack Williamson's '' Legion of Space'' and John W. Campbell's "Twilight". At the end of 1937, Campbell took over editorial duties under Tremaine's supervision, and the following year Tremaine was let go, giving Campbell more independence. Over the next few years Campbell published many stories that became classics in the field, including Isaac Asimov's ''Foundation'' series, A. E. van Vogt's ''Slan'', and several novels and stories by Robert A. Heinl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
