Galaxy

A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few thousand (10³) stars to giants with one hundred trillion (10¹⁴) stars, each orbiting their galaxy's own center of mass. Galaxies, are categorized according to their visual morphology, including elliptical,spiral, and irregular. Many galaxies are thought to have black holes at their active centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As of July 2015, EGSY8p7 is the oldest and most distant observed galaxy with a light travel distance of 13.2 billion light-years from Earth, and observed as it existed 570 million years after the Big Bang. Previously, as of May 2015, EGS-zs8-1 was the most distant known galaxy, estimated to have a light travel distance of 13.1 billion light-years away and to have 15% of the mass of the Milky Way.

Young Galaxy

History

Young Galaxy formed in Montreal as a duo including Stephen Ramsay and Catherine McCandless. Through that summer of 2005 and the spring of 2006 they recorded with appearances and contributions of friends at Jace Lasek’s Breakglass Studio. Their sound has been described as similar to the bands Slowdive, Galaxie 500 and Luna as well as Pink Floyd and Spiritualized. The band has toured in Canada, The United States and Europe, opening for Arcade Fire, Peter, Bjorn and John, Stars and Death Cab For Cutie. They later moved to Montreal, where they recorded their self-titled debut. The album was released April 24, 2007 on Arts & Crafts.

They recorded their second album Invisible Republic in Montreal at Hotel2Tango studio with Radwan Moumneh engineering (A Silver Mt. Zion, Pas Chic Chic) and at Breakglass Studios with Jace Lasek of The Besnard Lakes engineering. Invisible Republic was released independently on August 25, 2009. It was mixed by Tony Doogan (Mogwai, Belle & Sebastian, Snow Patrol) in Glasgow, Scotland. It was subsequently released in July 2010 in the US by Paper Bag Records, and received a long list nomination for the 2010 Polaris Music Prize. The band followed up in fall 2010 with YG No Art EP, an EP comprising unreleased tracks and remixes from the Invisible Republic sessions.

The United States of America (USA), commonly referred to as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major territories and various possessions. The 48 contiguous states and Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is in the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The territories are scattered about the Pacific Ocean and the Caribbean Sea. At 3.8 million square miles (9.842 million km²) and with over 320 million people, the country is the world's third or fourth-largest by total area and the third most populous. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States are also extremely diverse, and the country is home to a wide variety of wildlife.

Vietnamese language

Vietnamese ⁱ/ˌviɛtnəˈmiːz/ (tiếng Việt) is an Austroasiatic language that originated in the north of Vietnam and is the national and official language of the country. It is the native language of the Vietnamese (Kinh) people, as well as a first or second language for the many ethnic minorities of Vietnam. As the result of Vietnamese emigration and cultural influence, Vietnamese speakers are found throughout the world, notably in East and Southeast Asia, North America, Australia and Western Europe. Vietnamese has also been officially recognized as a minority language in the Czech Republic.

It is part of the Austroasiatic language family of which it has by far the most speakers (several times as many as the other Austroasiatic languages combined). Vietnamese vocabulary has borrowings from Chinese, and it formerly used a modified set of Chinese characters called chữ nôm given vernacular pronunciation. The Vietnamese alphabet (quốc ngữ) in use today is a Latin alphabet with additional diacritics for tones, and certain letters.

Acoustic guitar

An acoustic guitar is a guitar that produces sound acoustically—by transmitting the vibration of the strings to the air—as opposed to relying on electronic amplification (see Electric guitar). The sound waves from the strings of an acoustic guitar resonate through the guitar's body, creating sound. This typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings.

The main source of sound in an acoustic guitar is the string, which is plucked or strummed with the finger or with a plectrum. The string vibrates at a necessary frequency and also create many harmonics at various different frequencies. The frequencies produced can depend on string length, mass, and tension. The string causes the soundboard and sound box to vibrate, and as these have their own resonances at certain frequencies, they amplify some string harmonics more strongly than others, hence affecting the timbre produced by the instrument.

History

Gitterns, a small plucked guitar were the first small like guitar instruments created during the Middle Ages with a round back like that of a lute. Guitar like shaped instruments were not seen until the Renaissance era where the body and size began to take a guitar like shape.
