Surround sound

Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound from a 360° radius in the horizontal plane (2D) as opposed to "screen channels" (centre, [front] left, and [front] right) originating only from the listener's forward arc.

Surround sound is characterized by a listener location or sweet spot where the audio effects work best, and presents a fixed or forward perspective of the sound field to the listener at this location. The technique enhances the perception of sound spatialization by exploiting sound localization; a listener's ability to identify the location or origin of a detected sound in direction and distance. Typically this is achieved by using multiple discrete audio channels routed to an array of loudspeakers.

There are various surround sound based formats and techniques, varying in reproduction and recording methods along with the number and positioning of additional channels.

Star Wars

Star Wars is an American epic space opera franchise, centered on a film series created by George Lucas. It depicts the adventures of various characters "a long time ago in a galaxy far, far away".

The first film in the series, Star Wars (later subtitled Episode IV: A New Hope), was released on May 25, 1977 by 20th Century Fox and became a worldwide pop culture phenomenon. It was followed by the similarly successful sequels The Empire Strikes Back (1980) and Return of the Jedi (1983); these three films constitute the original Star Wars trilogy. A prequel trilogy was later released between 1999 and 2005, which received a more mixed reaction from critics and fans, compared to the original trilogy. All seven films were nominated for or won Academy Awards, and were commercial successes, with a combined box office revenue of $4.38 billion, making Star Wars the fourth highest-grossing film series. The series has spawned an extensive media franchise—the Star Wars expanded universe—including books, television series, computer and video games, and comic books, resulting in significant development of the series's fictional universe. Star Wars also holds a Guinness World Records title for the "Most successful film merchandising franchise." In 2012, the total value of the Star Wars franchise was estimated at USD $30.7 billion, including box-office receipts as well as profits from their video games and DVD sales.

Michelle Obama

Michelle LaVaughn Robinson Obama (born January 17, 1964) is an American lawyer and writer. She is married to the 44th and current President of the United States, Barack Obama, and is the first African-American First Lady of the United States. Raised on the South Side of Chicago, she is a graduate of Princeton University and Harvard Law School, and spent the early part of her legal career working at the law firm Sidley Austin, where she met Barack. Subsequently, she worked as part of the staff of Chicago mayor Richard M. Daley, and for the University of Chicago Medical Center.

Throughout 2007 and 2008, Obama helped campaign for her husband's presidential bid. She delivered a keynote address at the 2008 Democratic National Convention and spoke at the 2012 Democratic National Convention. She and her husband have two daughters together. She has become a fashion icon and role model for women, and an advocate for poverty awareness, nutrition, physical activity, and healthy eating.

First Lady

First Lady is an unofficial title used for the wife or hostess of a non-monarchical head of state or chief executive. The term is also used to describe a woman seen to be at the top of her profession or art. Collectively, the President of the United States and his spouse are known as the First Couple and, if they have a family, they are usually referred to as the First Family.

The term is sometimes used, particularly in the US, to refer to the spouse of other non-monarchical heads of state, even if they do not have that style in their own country. Some other countries have a title, formal or informal, that is or can be translated as first lady. The title is not normally used for the wife of a head of government who is not also head of state. It is sometimes employed for the wife of a prime minister; an incorrect usage, as prime ministers do not precede the head of state.

The term in the United States is also used to refer to wives of governors and, less formally, to wives of college and university presidents. It has even been used in reference to female spouses of men who were chairmen of major corporations. There has not yet been a female US president, but the term "First Gentleman" is used in the United States for the husband of a governor.
