Mengenlehreuhr
The ''Mengenlehreuhr'' (German for "Set Theory Clock") or Berlin-Uhr ("Berlin Clock") is the first public clock in the world that tells the time by means of illuminated, coloured fields, for which it entered the ''Guinness Book of Records'' upon its installation on 17 June 1975. Commissioned by the Senate of Berlin and designed by Dieter Binninger, the original full-sized Mengenlehreuhr was originally located at the Kurfürstendamm on the corner with Uhlandstraße. After the Senate decommissioned it in 1995, the clock was relocated to a site in Budapester Straße in front of Europa-Center, where it stands today. Time encoding The Mengenlehreuhr consists of 24 lights which are divided into one circular blinking yellow light on top to denote the seconds, two top rows denoting the hours and two bottom rows denoting the minutes. The clock is read from the top row to the bottom. The top row of four red fields denote five full hours each, alongside the second row, also of four red fi ...

Kryptos
''Kryptos'' is a sculpture by the American artist Jim Sanborn located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Since its dedication on November 3, 1990, there has been much speculation about the meaning of the four encrypted messages it bears. Of these four messages, the first three have been solved, while the fourth message remains one of the most famous unsolved codes in the world. The sculpture continues to be of interest to cryptanalysts, both amateur and professional, who are attempting to decipher the fourth passage. The artist has so far given four clues to this passage. Description The main part of the sculpture is located in the northwest corner of the New Headquarters Building courtyard, outside of the Agency's cafeteria. The sculpture comprises four large copper plates with other elements consisting of water, wood, plants, red and green granite, white quartz, and petrified wood. The most prominent feature is a large vertical S-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europa-Center
The Europa-Center is a building complex on Breitscheidplatz in the Charlottenburg district of Berlin, with a shopping mall and an high-rise tower. Erected between 1963 and 1965, it is today a historically preserved building. History of the site From 1897 a residential building was erected at the site of the present-day Europa-Center, vis-à-vis the Kaiser Wilhelm Memorial Church and likewise designed in a Neo-Romanesque style according to plans by Franz Schwechten. Then part of Berlin's fashionable "New West" (today also known as "City West"), it was, from 1916, home to the ''Romanisches Café'', a popular meeting place for writers, artists and people in the theatre business, as well as those who aspired to join them. During a RAF air raid in World War II on the night of 22/23 November 1943, the building burnt down and laid in ruins. After the war, the cleared premises were used only intermittently for more than a decade, according to need. Makeshift constructions were us ...

Clocks In Germany
A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year. Devices operating on several physical processes have been used over the millennia. Some predecessors to the modern clock may be considered as "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with the sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels., pp. 103–104., p. 31. Traditionally, in horology, the term ''clock'' was used for a striki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Individual Clocks
An individual is that which exists as a distinct entity. Individuality (or self-hood) is the state or quality of being an individual; particularly (in the case of humans) of being a person unique from other people and possessing one's own needs or goals, rights and responsibilities. The concept of an individual features in diverse fields, including biology, law, and philosophy. Etymology From the 15th century and earlier (and also today within the fields of statistics and metaphysics) ''individual'' meant " indivisible", typically describing any numerically singular thing, but sometimes meaning "a person". From the 17th century on, ''individual'' has indicated separateness, as in individualism. Law Although individuality and individualism are commonly considered to mature with age/time and experience/wealth, a sane adult human being is usually considered by the state as an "individual person" in law, even if the person denies individual culpability ("I followed instruct ...

Set Theory
Set theory is the branch of mathematical logic that studies sets, which can be informally described as collections of objects. Although objects of any kind can be collected into a set, set theory, as a branch of mathematics, is mostly concerned with those that are relevant to mathematics as a whole. The modern study of set theory was initiated by the German mathematicians Richard Dedekind and Georg Cantor in the 1870s. In particular, Georg Cantor is commonly considered the founder of set theory. The non-formalized systems investigated during this early stage go under the name of '' naive set theory''. After the discovery of paradoxes within naive set theory (such as Russell's paradox, Cantor's paradox and the Burali-Forti paradox) various axiomatic systems were proposed in the early twentieth century, of which Zermelo–Fraenkel set theory (with or without the axiom of choice) is still the best-known and most studied. Set theory is commonly employed as a foundational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Inventions
German inventions and discoveries are ideas, objects, processes or techniques invented, innovated or discovered, partially or entirely, in Germany or abroad by a person from Germany (that is, someone born in Germany – including to non-German parents – or born abroad with at least one German parent and who had the majority of their education or career in Germany).

Clock Of Flowing Time
The Clock of Flowing Time (german: Uhr der fließenden Zeit) is a 13 meter high water clock extending over three floors in the Berlin Europa-Center. The clock was designed by the French artist Bernard Gitton and set up in 1982. The water clock displays the time by filling glass spheres with brightly colored liquid, in a cycle that repeats every 12 hours. The whole system is controlled by a pendulum A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the ... swinging in the lower half of the clock.
