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.

Cun (unit)

The cun (Chinese: 寸; pinyin: cùn; Wade–Giles: ts'un; Japanese: sun; Korean: chon) is a traditional Chinese unit of length. Its traditional measure is the width of a person's thumb at the knuckle, whereas the width of the two forefingers denotes 1.5 cun and the width of all fingers side-by-side is three cuns. In this sense it continues to be used to chart acupuncture points on the human body in various uses of traditional Chinese medicine.

The cun was part of a larger system, and represented one-tenth of a chi ("Chinese foot"). In time the lengths were standardized, although to different values in different jurisdictions. (See chi (unit) for details).

In Hong Kong, using the traditional standard, it measures ~3.715 cm (~1.463 in) and is called a "tsun". In the twentieth century in the Republic of China, the lengths were standardized to fit with the metric system, and in current usage in People's Republic of China and Taiwan it measures 3 ¹⁄₃ cm (~1.312 in).

In Japan, the corresponding unit, sun (寸（すん）, sun), was standardized at ¹⁰⁰⁰⁄₃₃ mm (~3.030 cm, ~1.193 in, or ~0.09942 ft).

Switch (house DJ)

David James Andrew Taylor, better known his stage name Switch, is a British DJ, songwriter, sound engineer, and record producer. He is best known for his work with M.I.A.. In the fidget house genre, Switch runs his own music label "Dubsided", as well as the label Counterfeet, established in 2006 with fellow producer Sinden. He has released various singles under his own name, and is also well known for remixing and producing for many major artists. He is a former member of the American electronic dancehall group Major Lazer.

Most notably Switch has worked extensively with fellow British artist M.I.A. co-producing tracks on her albums Arular and Kala. For the latter, he travelled to work with M.I.A. in A. R. Rahman's Panchathan Record Inn and AM Studios and other locations such as Kodambakkam, Chennai and Trinidad and Tobago. He says "When you go somewhere like India, and especially Jamaica, it puts you in a different train of thought, outside of your usual working conditions. They use music as their voice; they use it for politics, for religion. So, I think for people that are struggling, they can use it to vent frustrations, or to celebrate.”

Switch (2012 film)

Switch is a documentary film on global energy directed by Harry Lynch, produced and distributed by Arcos Films, and featuring Scott W. Tinker, a geologist and energy researcher who runs the Bureau of Economic Geology, a 200-person research unit of The University of Texas at Austin. and is a professor at the Jackson School of Geosciences.

The film is part of a larger energy education and efficiency project, which also includes the Switch Energy Project website, with additional video content and educational programs. The website includes interviews with some of the world's leading energy policy analysts. Interviews including Ernie Moniz, former Under Secretary of Energy, Steven E. Koonin, Deputy Executive Director of the International Energy Agency, Richard Jones and physicist Richard A. Muller.

The film aims to be a nonpartisan, scientifically based exploration of the energy transition from the traditional energies of coal and oil to future energies. It has been accepted by many environmental groups, government agencies, fossil and renewable energy companies and academic institutions.

Switch (ad campaign)

Switch was an advertising campaign launched by Apple Computer, Inc. (now Apple, Inc.) on June 10, 2002. It featured what the company referred to as "real people" who had "switched" from the Microsoft Windows platform to the Mac. An international television and print ad campaign directed users to a website where various "myths" about the Mac platform were "dispelled". The television commercials were directed by Errol Morris.

Switchers

One of the people who appeared in the commercials, Ellen Feiss, gained immense notoriety overnight in a kind of Internet phenomenon. (Feiss was a friend of Morris's son Hamilton Morris, who also appeared in a commercial.

Localized versions of the commercials, with local "switchers", aired in Iceland and Japan.

Certain ads featured celebrities, such as Tony Hawk, DJ Q-Bert, Yo-Yo Ma, Kelly Slater, Will Ferrell, and the members of De La Soul.

Campaign

The Switch campaign, while distinctive, was not very effective, and was gradually phased out in 2003. This can be somewhat blamed, however, for the Macintosh lineup as the iMac G3 was becoming obsolete while the new iMac G4 that was showcased was considerably more expensive than comparable Wintel offerings. The advertising concept of the Mac's advantages over the PC was later revived for the Get a Mac campaign in 2006.
