Dettifoss2
Dettifoss () is a waterfall in Vatnajökull National Park in Northeast Iceland, and is reputed to be the second most powerful waterfall in Europe after the Rhine Falls. Dettifoss is situated on the Jökulsá á Fjöllum river, which flows from the Vatnajökull glacier and collects water from a large area in Northeast Iceland. The sediment-rich runoff colours the water a greyish white. The falls are wide and have a drop of down to the canyon Jökulsárgljúfur.

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Second
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chronology Of The Universe
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level. The Planck Collaboration in 2015 published the estimate of 13.799 ± 0.021 billion years ago (68% confidence interval). See PDF: page 32, Table 4, Age/Gyr, last column. Outline Chronology in five stages For the purposes of this summary, it is convenient to divide the chronology of the universe since it originated, into five parts. It is generally considered meaningless or unclear whether time existed before this chronology: The very early universe The first picosecond (10−12) of cosmic time. It includes the Planck epoch, during which currently established laws of physics may not apply; the emergence in stages of the four known fundamental interactions or ...

Prometheus (2012 Film)
''Prometheus'' ( ) is a 2012 science fiction horror film co-produced and directed by Ridley Scott, written by Jon Spaihts and Damon Lindelof and starring Noomi Rapace, Michael Fassbender, Guy Pearce, Idris Elba, Logan Marshall-Green, and Charlize Theron. It is set in the late 21st century and centers on the crew of the spaceship ''Prometheus'' as it follows a star map discovered among the artifacts of several ancient Earth cultures. Seeking the origins of humanity, the crew arrives on a distant world and discovers a threat that could cause the extinction of the human species. Development of the film began in the early 2000s as a fifth installment in the ''Alien'' franchise. Scott and director James Cameron developed ideas for a film that would serve as a prequel to Scott's 1979 science-fiction horror film ''Alien''. In 2002, the development of ''Alien vs. Predator'' took precedence, and the project remained dormant until 2009 when Scott again showed interest. Spaihts wr ...

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 become po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jón Leifs
Jón Leifs (born Jón Þorleifsson on 1 May 1899 – 30 July 1968) was an Icelandic composer, pianist, and conductor. Life Jón Leifs was born ''Jón Þorleifsson,'' at the farm Sólheimar, then in the Húnavatnssýsla, northwestern Iceland. He left for Germany in 1916 to study at the Leipzig Conservatory. He graduated in 1921 having studied piano with Robert Teichmüller, but decided not to embark on a career as a pianist, devoting his time instead to conducting and composing. During this period he also studied composition with Ferruccio Busoni, who urged him to "follow his own path in composition". In the 1920s Jón Leifs conducted a number of symphony orchestras in Germany, Czechoslovakia, Norway and Denmark, thus becoming the only internationally successful Icelandic conductor to date, although he failed to obtain a fixed position. During a tour of Norway, the Faroe Islands and Iceland with the Hamburger Philharmoniker, he gave the very first symphonic concerts in Iceland ...

Mývatn
() is a shallow lake situated in an area of active volcanism in the north of Iceland, not far from Krafla volcano. It has a high amount of biological activity. The lake and the surrounding wetlands provides a habitat for a number of waterbirds, especially ducks. The lake was created by a large basaltic lava eruption 2300 years ago, and the surrounding landscape is dominated by volcanic landforms, including lava pillars and rootless vents (pseudocraters). The effluent river is known for its rich fishing for brown trout and Atlantic salmon. The name of the lake ( Icelandic ("midge") and ("lake"); "the lake of midges") comes from the large numbers of midges present in the summer. The name is sometimes used not only for the lake but the whole surrounding inhabited area. The river , the lake and the surrounding wetlands are protected as a nature reserve (the – Nature Conservation Area, which occupies ). Since the year 2000, a marathon around the lake takes place in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Húsavík
Húsavík () is a town in Norðurþing municipality on the north coast of Iceland on the shores of Skjálfandi bay with 2,307 inhabitants. The most famous landmark of the town is the wooden church Húsavíkurkirkja, built in 1907. Húsavík is served by Húsavík Airport. Overview Income is derived from tourism and fishing, as well as retail and small industry. Until recently, Húsavík was the export harbour for silica that was extracted from nearby lake Mývatn. According to the ''Landnámabók'' ("Book of Settlement"), Húsavík was the first place in Iceland to be settled by a Norseman. The Swedish Viking Garðar Svavarsson stayed there for one winter around 870 A.D. When he left the island in spring of 870, after a winter's stay, he left behind a man named Náttfari and two slaves, a man and a woman, and they established a farm here. The name of the town means "bay of houses", probably referring to Garðar's homestead, which may have been the only houses then in Iceland. ...

Diamond Circle
The Diamond Circle ( is, Demantshringurinn ) is a popular tourist route around Húsavík and Lake Mývatn in North Iceland. The route is fully paved and easily accessible during the summer. The southern section of the route follows Route 1 (Ring road) from Akureyri, before turning north along Route 862, the new road to Dettifoss. Then it joins Route 85 at Ásbyrgi Canyon and follows the coast through Húsavík and eventually re-joining Route 1. The four primary stops on the route are The town of Húsavík, Ásbyrgi Canyon, Lake Mývatn and Dettifoss Waterfall, the most powerful waterfall in Europe. Other stops include Vatnajökull National Park, Goðafoss Waterfall, Dimmuborgir (Dark Castles), Eider Falls, The Whispering Cliffs and Laugar. The Diamond Circle covers an area rich in volcanic and geothermal features. The completion of the 55km new paved road to Dettifoss, Route 862, replaced a difficult old gravel road which was impassable during winter. The road was opened ...

Gravel Road
A gravel road is a type of unpaved road surfaced with gravel that has been brought to the site from a quarry or stream bed. They are common in less-developed nations, and also in the rural areas of developed nations such as Canada and the United States. In New Zealand, and other Commonwealth countries, they may be known as metal roads. They may be referred to as "dirt roads" in common speech, but that term is used more for unimproved roads with no surface material added. If well constructed and maintained, a gravel road is an all-weather road. Characteristics Construction Compared to sealed roads, which require large machinery to work and pour concrete or to lay and smooth a bitumen-based surface, gravel roads are easy and cheap to build. However, compared to dirt roads, all-weather gravel highways are quite expensive to build, as they require front loaders, dump trucks, graders, and roadrollers to provide a base course of compacted earth or other material, sometimes maca ...

Asphalt Concrete
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century. It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The process was refined and enhanced by Belgian-American inventor Edward De Smedt. The terms ''asphalt'' (or ''asphaltic'') ''concrete'', ''bituminous asphalt concrete'', and ''bituminous mixture'' are typically used only in engineering and construction documents, which define concrete as any composite material composed of mineral aggregate adhered with a binder. The abbreviation, ''AC'', is sometimes used for ''asphalt concrete'' but can also denote ''asphalt content'' or ''asphalt cement'', ...

Urriðafoss
Urriðafoss (, "sea trout waterfall") is a waterfall located in the river Þjórsá in southwest Iceland. With a flow rate of 360 m³/s, it has the highest average water flow of any waterfall in Iceland, and the second highest in Europe behind the Rheinfall. The Fossafélagið Títan company was given permission in 1927 to build a power plant in Urriðafoss in connection with a railway to Reykjavík from the waterfall. It did not happen but now Landsvirkjun is planning to build hydropower stations on the lower part of Þjórsár river, at Urriðafoss and Núpur. The proposed Urriðafoss Power Plant is expected to have a capacity of approximately 125 MW and a power-generating capacity of 930 GWh per year. The powerhouse will be underground and a tunnel leading from the powerhouse will open out into Þjórsá river below Urriðafoss waterfall. The waterfall is expected to disappear if the powerhouse is built. Local residents in the area are protesting against the construction in ...
