Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time is a 1995 best-selling book by Dava Sobel about John Harrison, an 18th-century clockmaker who created the first clock (chronometer) sufficiently accurate to be used to determine longitude at sea—an important development in navigation.
Longitude lines are perpendicular to and latitude lines are parallel to the Equator. A geographic coordinate system ( GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used of the various spatial reference ...
Science fiction is "a literary genre whose necessary and sufficient conditions are the presence and interaction of estrangement and cognition, and whose main formal device is an imaginative framework alternative to the author's empirical environment." [6] [26] Thomas M. Disch. 1973.
World map. A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
Latitude is given as an angle that ranges from −90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude and longitude are used together as a coordinate pair to specify a location on the surface of the Earth.
Linguistics has an intrinsic connection to science fiction stories given the nature of the genre and its frequent use of alien settings and cultures. As mentioned in Aliens and Linguists: Language Study and Science Fiction by Walter E. Meyers, science fiction is almost always concerned with the idea of communication, such as communication with aliens and machines, or communication using dead ...
ISO 6709, Standard representation of geographic point location by coordinates, is the international standard for representation of latitude, longitude and altitude for geographic point locations. The first edition ( ISO 6709:1983) was developed by ISO/IEC JTC 1 /SC 32. Later the standard was transferred to ISO/TC211, Geographic information ...
Fictional country. A fictional country is a country that is made up for fictional stories, and does not exist in real life, or one that people believe in without proof. Sailors have always mistaken low clouds for land masses, and in later times this was given the name Dutch capes. [1] Other fictional lands appear most commonly as settings or ...
