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.

Yoga

Yoga (/ˈjoʊɡə/;Sanskrit, Listen) is a physical, mental, and spiritual practice or discipline which originated in India. There is a broad variety of schools, practices, and goals in Hinduism, Buddhism and Jainism. Among the most well-known types of yoga are Hatha yoga and Rāja yoga.

The origins of yoga have been speculated to date back to pre-Vedic Indian traditions, is mentioned in the Rigveda, but most likely developed around the sixth and fifth centuries BCE, in ancient India's ascetic and śramaṇa movements. The chronology of earliest texts describing yoga-practices is unclear, varyingly credited to Hindu Upanishads and Buddhist Pāli Canon, probably of third century BCE or later. The Yoga Sutras of Patanjali date from the first half of the 1st millennium CE, but only gained prominence in the West in the 20th century. Hatha yoga texts emerged around the 11th century with origins in tantra.

Yoga gurus from India later introduced yoga to the west, following the success of Swami Vivekananda in the late 19th and early 20th century. In the 1980s, yoga became popular as a system of physical exercise across the Western world. Yoga in Indian traditions, however, is more than physical exercise, it has a meditative and spiritual core. One of the six major orthodox schools of Hinduism is also called Yoga, which has its own epistemology and metaphysics, and is closely related to Hindu Samkhya philosophy.

Yoga (Hindu astrology)

As per Jyotisa a Yoga is given rise to when one planet, sign or house is related to another of the same kind or different kind by way of placement, aspect or conjunction. It is the active consideration of planetary yogas and the active consideration of the planetary Dashas i.e. directional effects, which are the two most important factors that distinguish Hindu astrology from Western astrology.

Background

Laghu Parashari is the concise version of the predictive side of the Hora Shastra, and the Parashari System is most widely followed, having stood the test of time and because it is simple and unambiguous. The ancient Hindu astrologers seem to have confined their exercises to the seven planets – the Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn; Rahu and Ketu, these two that are mathematical points, are referred to but rarely. Parashara also refers to five more Chayagrahas which are all actually invisible mathematical solar positions but having impact on the life of individuals and nations. The Rigveda does refer to the total of thirty-four, comprising twenty-seven Nakshatra-divisions of the Zodiac and the seven planets which was the general format then in use. However, elsewhere it also refers to the total of forty-nine by adding to the said thirty-four the two Chayagrahas (the lunar nodes), the twelve rasis (signs) and the Ayanamsa. Varahamihira favoured Satyacharya’s Dasha system though he says many had spoiled it by useless multiplications but Satyacharya did not deviate from the basic Parashari principles. Because of there being nine active planets and equally active twelve signs (including their numerous sub-divisions) and twenty seven nakshatra divisions, yoga-formations are unavoidable.

1-center problem

The 1-center problem or minimax or minmax location problem is a classical combinatorial optimization problem in operations research of facilities location type. In its most general case the problem is stated as follows: given a set of n demand points, a space of feasible locations of a facility and a function to calculate the transportation cost between a facility and any demand point, find a location of the facility which minimizes the maximum facility-demand point transportation cost.

The simple special case when the feasible locations and demand points are in the plane with Euclidean distance as transportation cost (planar minmax Euclidean facility location problem, Euclidean 1-center problem in the plane, etc.), it is also known as the smallest circle problem. Its generalization to n-dimensional Euclidean spaces is known as the smallest enclosing ball problem. A further generalization (weighted Euclidean facility location) is when the set of weights is assigned to demand points and the transportation cost is the sum of the products of distances by the corresponding weights. Another special case, the closest string problem, arises when the inputs are strings and their distance is measured using Hamming distance.
