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.

Sun (Thomas Bergersen album)

Sun is the second stand-alone production album created by Thomas J. Bergersen from Two Steps from Hell, released on September 30, 2014. The release contains 16 tracks, featuring vocal performances by Merethe Soltvedt, Molly Conole and other vocalists. The album cover and artwork are designed by Bergersen himself. The album was announced for pre-order on September 9 across iTunes, Amazon, and CD Baby, with the tracks "Empire of Angels," "Final Frontier," and "Starchild" made available on iTunes prior to the full release. In addition, a signed limited deluxe edition CD version has been scheduled for somewhere in 2015, set to include additional music, notes on each track written by Thomas, and a large-size poster featuring his artwork.

Sun (Cat Power album)

Sun is the ninth studio album by American musician Cat Power. Her first album of all-original material since 2006's The Greatest, it was released on September 3, 2012, in the United Kingdom and in the United States on September 4, 2012, via Matador Records. The album was issued in a variety of formats, including a limited edition deluxe LP containing a 7" vinyl of bonus tracks.

The album's lead single, "Ruin", was released for free download at Matador Record's store on June 20, 2012. A music video for album opener "Cherokee", directed by Marshall, was later released, while an ambient remix of the song by Nicolas Jaar is available to download from Cat Power's official website. The song was premièred on NPR's All Songs Considered on June 26, whose host Bob Boilen described the album as "[going in] yet another direction. A lot more drive, a lot more electronics, drum machines, synths—it's very bold."

On April 10, 2013, Cat Power performed the previously unreleased track "Bully" on the opening episode of the forty-second series of Later... with Jools Holland. Immediately following the broadcast, a new version of the album containing "Bully" as a bonus track was made available for download through iTunes.

Utility frequency

The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the frequency of the oscillations of alternating current (AC) in an electric power grid transmitted from a power plant to the end-user. In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz. Current usage by country or region is given in the list of mains power around the world.

During the development of commercial electric power systems in the late 19th and early 20th centuries, many different frequencies (and voltages) had been used. Large investment in equipment at one frequency made standardization a slow process. However, as of the turn of the 21st century, places that now use the 50 Hz frequency tend to use 220–240 V, and those that now use 60 Hz tend to use 100–127 V. Both frequencies coexist today (Japan uses both) with no great technical reason to prefer one over the other and no apparent desire for complete worldwide standardization.

Solar (room)

The solar was a room in many English and French medieval manor houses, great houses and castles, generally situated on an upper storey, designed as the family's private living and sleeping quarters. In such houses, the main ground-floor room was known as the Great Hall, in which all members of the household, including tenants, employees and servants, would eat. Those of highest status would be at the end, often on a raised dais, and those of lesser status further down the hall. But a need was felt for more privacy to be enjoyed by the head of the household, and, especially, by the senior women of the household. The solar was a room for their particular benefit, in which they could be alone and away from the hustle, bustle, noise and smells (including cooking smells) of the Great Hall.

The solar was generally smaller than the Great Hall, because it was not expected to accommodate so many people, but it was a room of comfort and status, and usually included a fireplace and often decorative woodwork or tapestries/wall hangings.

Solar (Red Garland album)

Solar is an album by jazz musician Red Garland, recorded in 1962 and released the same year on Jazzland as JLP 73.
