Ramon Llull (en castellano : Raimundo Lulio ) (c. 1232 - 29 de junio de 1315 ), también conocido como Raimundus o Raymundus Lullus en latín , como رامون لیول en árabe , como Raymond Lully por los ingleses o como Raymond Lulle por los franceses , fue un laico próximo a los franciscanos (pudo haber pertenecido a la Orden Tercera de los frailes Menores ), filósofo , poeta , místico , teólogo y misionero mallorquín del siglo XIII . Fue declarado beato y su fiesta se conmemora el 27 de noviembre . Se le considera uno de los creadores del catalán literario [ 1 ] y uno de los primeros en usar una lengua neolatina para expresar conocimientos filosóficos , científicos y técnicos , además de textos novelísticos . Se le atribuye la invención de la rosa de los vientos y del nocturlabio . [ 2 ]

Coordinates : UZB76 (sometimes referred to as UVB76 , but recently MDZhB ) is the call sign of a shortwave radio station that usually broadcasts on the frequency 4625 kHz ( AM suppressed lower sideband ). It is known among English speaking radio listeners by the nickname The Buzzer , and by Russian listeners as Russian : жужжалка 'the hummer'. [ 1 ] It features a short, monotonous buzz tone , repeating at a rate of approximately 25 tones per minute, for 24 hours per day. The station has been observed since around 1982. [ 2 ] On rare occasions, the buzzer signal is interrupted and a voice transmission in Russian takes place. [ 3 ] Despite much speculation, the actual purpose of this station remains unknown to the public. [ 4 ] [ edit ] Normal transmission

Icono de un Meme Un meme (o mem ) es, en las teorías sobre la difusión cultural , la unidad teórica de información cultural [ 1 ] transmisible de un individuo a otro, o de una mente a otra, o de una generación a la siguiente. Es un neologismo acuñado por Richard Dawkins en El gen egoísta ( The Selfish Gene ), por la semejanza fonética con «gene» — gen en idioma inglés — y para señalar la similitud con « memoria » y « mimesis ». [ editar ] La tesis de Dawkins Según Dawkins, poseemos dos tipos de procesadores informativos distintos:
" Why The Future Doesn't Need Us " is an article written by Bill Joy (then Chief Scientist at Sun Microsystems ) in the April 2000 issue of Wired magazine. In the article, he argues (quoting the sub title) that "Our most powerful 21st-century technologies — robotics , genetic engineering , and nanotech — are threatening to make humans an endangered species ." Joy warns: While some critics have characterized Joy's stance as obscurantism or neo-Luddism , others share his concerns about the consequences of rapidly expanding technology. [ 1 ]
Grey goo (alternatively spelled gray goo ) is a hypothetical end-of-the-world scenario involving molecular nanotechnology in which out-of-control self-replicating robots consume all matter on Earth while building more of themselves, [ 1 ] [ 2 ] a scenario that has been called ecophagy ("eating the environment"). [ 3 ] The original idea assumed machines designed to have this capability, while popularizations have assumed that machines might somehow gain this capability by accident. Self-replicating machines of the macroscopic variety were originally described by mathematician John von Neumann , and are sometimes referred to as von Neumann machines .
Moravec's paradox is the discovery by artificial intelligence and robotics researchers that, contrary to traditional assumptions, high-level reasoning requires very little computation, but low-level sensorimotor skills require enormous computational resources. The principle was articulated by Hans Moravec , Rodney Brooks , Marvin Minsky and others in the 1980s. As Moravec writes, "it is comparatively easy to make computers exhibit adult level performance on intelligence tests or playing checkers, and difficult or impossible to give them the skills of a one-year-old when it comes to perception and mobility." Linguist and cognitive scientist Steven Pinker considers this the most significant discovery uncovered by AI researchers.
The (French) sign reads 3 January 1900 instead of 3 January 2000 The Year 2000 problem (also known as the Y2K problem , the Millennium bug , the Y2K bug , or simply Y2K ) was a problem for both digital (computer-related) and non-digital documentation and data storage situations which resulted from the practice of abbreviating a four-digit year to two digits. In 1997, The British Standards Institute (BSI) developed a standard, DISC PD2000-1, [ 1 ] which defines "Year 2000 Conformity requirements" as four rules:
A lucid dream is any dream in which one is aware that one is dreaming. The term was coined by the Dutch psychiatrist and writer Frederik (Willem) van Eeden (1860–1932). [ 1 ] In a lucid dream, the dreamer can exert some degree of control over their participation within the dream or be able to manipulate their imaginary experiences in the dream environment. [ 2 ] Lucid dreams can be realistic and vivid. [ 3 ] It is shown that there are higher amounts of beta-1 frequency band (13–19 Hz) experienced by lucid dreamers, hence there is an increased amount of activity in the parietal lobes making lucid dreaming a conscious process. [ 4 ] Lucid dreaming has been researched scientifically, and its existence is well established. [ 5 ] [ 6 ] [ edit ] Scientific history
Socotra ( Arabic : سُقُطْرَى Suquṭra ), also spelled Soqotra , is a small archipelago of four islands in the Indian Ocean . The largest island, also called Socotra, is about 95% of the landmass of the archipelago. It lies some 240 kilometres (150 mi) east of the Horn of Africa and 380 kilometres (240 mi) south of the Arabian Peninsula . [ 2 ] The island is very isolated and through the process of speciation , a third of its plant life is found nowhere else on the planet.

"Sea Shadow" redirects here. For the 2011 Emirati film, see Sea Shadow (film) . Sea Shadow (IX-529) was an experimental stealth ship built by Lockheed for the United States Navy to determine how a low radar profile might be achieved and to test high stability hull configurations which have been used in oceanographic ships. [ edit ] Development Sea Shadow was built in 1984 to examine the application of stealth technology on naval vessels. It was used in secret but normal service until a public debut in 1993.
New Wave is a term applied to science fiction produced in the 1960s and 1970s and characterized by a high degree of experimentation, both in form and in content, a "literary" or artistic sensibility, and a focus on "soft" as opposed to hard science. New Wave writers often saw themselves as part of the modernist tradition and sometimes mocked the traditions of pulp science fiction, which some of them regarded as stodgy, adolescent and poorly written.

Johnston Atoll is a 1.03 sq mi (2.7 km 2 ) atoll in the North Pacific Ocean [ 1 ] about 750 nmi (860 mi ; 1,390 km ) west of Hawaii. The atoll, which is located on the coral reef platform, comprises four islands. Johnston and Sand islands are both enlarged natural features, while North ( Akau ) and East ( Hikina ) are two artificial islands formed by coral dredging. [ 1 ] Johnston Atoll is grouped as one of the United States Minor Outlying Islands . For nearly 70 years, the atoll was under the control of the American military .
