Wonders Of The Universe
''Wonders of the Universe'' is a 2011 television series produced by the BBC, Discovery Channel, and Science Channel, hosted by physicist Professor Brian Cox. ''Wonders of the Universe'' was first broadcast in the United Kingdom on BBC Two from 6 March 2011. The series comprises four episodes, each of which focuses on an aspect of the universe and features a 'wonder' relevant to the theme. It follows on from Cox's 2010 series for the BBC, ''Wonders of the Solar System''. An accompanying book with the same title was also published. Episodes 1. "Destiny" In the first episode, Cox considers the fundamental nature of time while pondering the ruins at Chankillo in Peru. He explores the familiarly brief cycles of time that define the lives of humans on Earth (such as days, months, and years), and compares them to the cycles of time on a cosmically universal scale (such as the Solar System's 250 million year circuit around the Milky Way). At the Perito Moreno Glacier Cox introduces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Milky Way
The Milky Way is the galaxy that includes our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term ''Milky Way'' is a translation of the Latin ', from the Greek ('), meaning "milky circle". From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies. The Milky Way is a barred spiral galaxy with an estimated D25 isophotal diameter of , but only about 1,000 light years thick at the spiral arms (more at the bulge ...

Eduard Bohlen
''Eduard Bohlen'' was a ship that was wrecked on the Skeleton Coast of German Southwest Africa (now Namibia) on 5 September 1909 in a thick fog. The wreck currently lies in the sand from the shoreline. Service The ship was a 2,272 gross ton cargo ship with a length of . In September 1909, it ran aground in thick fog and was wrecked at Conception Bay while on a voyage from Swakopmund to Table Bay. Wreck The Bohlen lies near two wrecks of ''Otavi'', which foundered here and sank in 1945, and , among the many wrecks of the Skeleton Coast. In popular culture A 1990s documentary on another vessel lost on the same beach miles away, the MV ''Dunedin Star'', also featured the Bohlen. The wreck was featured in the 2011 television series ''Wonders of the Universe ''Wonders of the Universe'' is a 2011 television series produced by the BBC, Discovery Channel, and Science Channel, hosted by physicist Professor Brian Cox.

Namib Desert
The Namib ( ; pt, Namibe) is a coastal desert in Southern Africa. The name is of Khoekhoegowab origin and means "vast place". According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to inland to the foot of the Great Escarpment. Annual precipitation ranges from in the most arid regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and con ...

Skeleton Coast
The Skeleton Coast is the northern part of the Atlantic coast of Namibia and south of Angola from the Kunene River south to the Swakop River, although the name is sometimes used to describe the entire Namib Desert coast. The indigenous San people (formerly known as Bushmen), of the Namibian interior called the region "The Land God Made in Anger", while Portuguese sailors once referred to it as "The Gates of Hell". On the coast, the upwelling of the cold Benguela current gives rise to dense ocean fogs (called ''cassimbo'' by the Angolans) for much of the year. The winds blow from land to sea, rainfall rarely exceeds annually, and the climate is highly inhospitable. There is a constant, heavy surf on the beaches. In the days before engine-powered ships and boats, it was possible to get ashore through the surf but impossible to launch from the shore. The only way out was by going through a marsh hundreds of kilometres long and only accessible via a hot and arid desert. The c ...

Red Dwarf
''Red Dwarf'' is a British science fiction comedy franchise created by Rob Grant and Doug Naylor, which primarily consists of a television sitcom that aired on BBC Two between 1988 and 1999, and on Dave since 2009, gaining a cult following. The series follows low-ranking technician Dave Lister, who awakens after being in suspended animation for three million years to find that he is the last living human, and that he is alone on the mining spacecraft ''Red Dwarf''—save for a hologram his deceased bunkmate Arnold Rimmer and "Cat", a life form which evolved from Lister's pregnant cat. As of 2020, the cast includes Chris Barrie as Rimmer, Craig Charles as Lister, Danny John-Jules as Cat, Robert Llewellyn as the sanitation droid Kryten, and Norman Lovett as the ship's computer, Holly. To date, twelve series of the show have aired, (including one miniseries), in addition to a feature-length special ''The Promised Land''. Four novels were published from 1989 to 1996. Two pilo ...

Proxima Centauri
Proxima Centauri is a small, low-mass star located away from the Sun in the southern constellation of Centaurus. Its Latin name means the 'nearest tarof Centaurus'. It was discovered in 1915 by Robert Innes and is the nearest-known star to the Sun. With a quiescent apparent magnitude of 11.13, it is too faint to be seen with the unaided eye. Proxima Centauri is a member of the Alpha Centauri star system, being identified as component Alpha Centauri C, and is 2.18° to the southwest of the Alpha Centauri AB pair. It is currently from AB, which it orbits with a period of about 550,000 years. Proxima Centauri is a red dwarf star with a mass about 12.5% of the Sun's mass (), and average density about 33 times that of the Sun. Because of Proxima Centauri's proximity to Earth, its angular diameter can be measured directly. Its actual diameter is about one-seventh (14%) the diameter of the Sun. Although it has a very low average luminosity, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stellar Evolution
Stellar evolution is the process by which a star changes over the course of time. Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the age of the universe. The table shows the lifetimes of stars as a function of their masses. All stars are formed from collapsing clouds of gas and dust, often called nebulae or molecular clouds. Over the course of millions of years, these protostars settle down into a state of equilibrium, becoming what is known as a main-sequence star. Nuclear fusion powers a star for most of its existence. Initially the energy is generated by the fusion of hydrogen atoms at the core of the main-sequence star. Later, as the preponderance of atoms at the core becomes helium, stars like the Sun begin to fuse hydrogen along a spherical shell surrounding the core. This process causes the star to gradually grow in size, passin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entropy
Entropy is a scientific concept, as well as a measurable physical property, that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory. It has found far-ranging applications in chemistry and physics, in biological systems and their relation to life, in cosmology, economics, sociology, weather science, climate change, and information systems including the transmission of information in telecommunication. The thermodynamic concept was referred to by Scottish scientist and engineer William Rankine in 1850 with the names ''thermodynamic function'' and ''heat-potential''. In 1865, German physicist Rudolf Clausius, one of the leading founders of the field of thermodynamics, defined it as the quotient of an infinitesimal amount of h ...

Arrow Of Time
The arrow of time, also called time's arrow, is the concept positing the "one-way direction" or "asymmetry" of time. It was developed in 1927 by the British astrophysicist Arthur Eddington, and is an unsolved general physics question. This direction, according to Eddington, could be determined by studying the organization of atoms, molecules, and bodies, and might be drawn upon a four-dimensional relativistic map of the world ("a solid block of paper"). Physical processes at the microscopic level are believed to be either entirely or mostly time-symmetric: if the direction of time were to reverse, the theoretical statements that describe them would remain true. Yet at the macroscopic level it often appears that this is not the case: there is an obvious direction (or ''flow'') of time. Overview The symmetry of time ( T-symmetry) can be understood simply as the following: if time were perfectly symmetrical, a video of real events would seem realistic whether played for ...

Kolmanskop
Kolmanskop (Afrikaans for “Coleman's head”, german: Kolmannskuppe) is a ghost town in the Namib in southern Namibia, ten kilometres inland from the port town of Lüderitz. It was named after a transport driver named Johnny Coleman who, during a sand storm, abandoned his ox wagon on a small incline opposite the settlement. Once a small but very rich mining village, it is now a tourist destination run by the joint firm Namibia- De Beers. History Foundation and peak In 1908, in what was then German South-West Africa, the worker Zacharias Lewala found a diamond while working in this area and showed it to his supervisor, the German railway inspector August Stauch. Realizing the area was rich in diamonds, German miners began settlement, and soon after the German Empire declared a large area as a "'' Sperrgebiet''", starting to exploit the diamond field. Driven by the enormous wealth of the first diamond miners, the residents built the village in the architectural style of a German ...
