Sun

The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 109 times that of Earth, and it has a mass about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.About three quarters of the Sun's mass consists of hydrogen; the rest is mostly helium, with much smaller quantities of heavier elements, including oxygen, carbon, neon and iron.

The Sun is a G-type main-sequence star (G2V) based on spectral class and it is informally referred to as a yellow dwarf. It formed approximately 4.567 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became increasingly hot and dense, eventually initiating nuclear fusion in its core. It is thought that almost all stars form by this process.

Sol (given name)

Sol is a given name, usually a form of "Solomon". Notable people with the name include:

Sol (computer)

The SOL is a rugged, waterproof solar-powered laptop computer intended for use in African schools that do not have access to an electrical network. Sol was created by London, Ontario-based WeWi Telecommunications.

The laptop is preloaded with the Ubuntu variant of Linux.

Design and features

The SOL is available in two editions, a standard edition and the Marine edition which uses hydrophobic coating to provide water repletion instead of waterproofing the laptop. The laptop has a reinforced polymer-based clam shell casing that houses the solar panels and makes the laptop more durable. The device uses four detachable monocrystalline photovoltaic panels which fold into the unit.

Developer

WeWi Telecommunications was founded by David M. Snir in 2009 as an Internet service provider and then shifted to research and development. The company does ad hoc disaster recovery and connectivity services.

Man (Middle-earth)

In J. R. R. Tolkien's Middle-earth books, such as The Hobbit and The Lord of the Rings, the terms Man and Men refer to humankind – in contrast to Elves, Dwarves, Orcs and other humanoid races – and does not denote gender.

The Elves call the race of Men Atani in Quenya, literally meaning "Second People" (the Elves being the First), but also Hildor (Followers), Apanónar (After-born), and Fírimar or Firyar (Mortals). Less charitably they were called Engwar (The Sickly), owing to their susceptibility to disease and old age, and their generally unlovely appearance in the Elves' eyes. The name Atani becomes Edain in Sindarin, but this term is later applied only to those tribes of Men who are friendly to the Elves. Other names appear in Sindarin as Aphadrim, Eboennin, and Firebrim or Firiath.

Origins

The race of Men is the second race of beings created by the One God, Ilúvatar. Because they awoke at the start of the Years of the Sun, while the Elves awoke at the start of the First Age during the Years of the Trees, they are called the Afterborn by the Elves.

Man (disambiguation)

A man is an adult male Human. Man may also mean the entire human species, its individuals and nearest extinct relatives. See man (word) for the etymology.

Mandø

Mandø is one of the Danish Wadden Sea islands off the southwest coast of Jutland, Denmark in the Wadden Sea, part of the North Sea. The island covers an area of 7.63 km² and has 62 inhabitants. The island is situated approximately 12 kilometers southwest of the ancient town of Ribe.

Mandø is barely accessible at high tide over an unpaved surface level causeway of about four kilometers in length that connects the island to the mainland. Extensive mudflats and tidal marshes encircle the island and provide breeding areas to multitudes of birds and other organisms. In the past centuries a large earthen dike has been constructed around the perimeter of the island, although substantially set back from the shoreline. This artifice has allowed conventional farming in the form of grain growing and sheep grazing. Mandø is technically a hallig, although it is far from the ten German islands commonly described by that term. The name was formerly often spelled Manø.

Logistics of access

Conventional motor vehicles can access Mandø Island via a causeway unpaved roadway, although this route is compromised in storms at high tide. The nearest village on the mainland which is the gateway to Mandø Island is Vester Vedsted. This simple causeway road is no more than copious gravel laid down on an immense mudflat, with required frequent periodic maintenance of added gravels. Alternatively many visitors reach the island by way of a specially designed tractor pulled bus with greatly oversized tires. This vehicle is capable of traversing some of the firmer mudflats, but only at the lowest tides. In any case private vehicles or the "Mandø bus" leave the mainland at the point of the Wadden Sea Centre, which offers nature information and boasts a small museum devoted to the natural history of Mandø. Mandø is located midway between the two larger islands Fanø and Rømø which are connected to the mainland by a ferry and a road running across a causeway, respectively.
