Randomness

Randomness is the lack of pattern or predictability in events. A random sequence of events, symbols or steps has no order and does not follow an intelligible pattern or combination. Individual random events are by definition unpredictable, but in many cases the frequency of different outcomes over a large number of events (or "trials") is predictable. For example, when throwing two dice, the outcome of any particular roll is unpredictable, but a sum of 7 will occur twice as often as 4. In this view, randomness is a measure of uncertainty of an outcome, rather than haphazardness, and applies to concepts of chance, probability, and information entropy.

The fields of mathematics, probability, and statistics use formal definitions of randomness. In statistics, a random variable is an assignment of a numerical value to each possible outcome of an event space. This association facilitates the identification and the calculation of probabilities of the events. Random variables can appear in random sequences. A random process is a sequence of random variables whose outcomes do not follow a deterministic pattern, but follow an evolution described by probability distributions. These and other constructs are extremely useful in probability theory and the various applications of randomness.

Sweetness

Sweetness is one of the five basic tastes and is universally regarded as a pleasurable experience, except perhaps in excess. Foods rich in simple carbohydrates such as sugar are those most commonly associated with sweetness, although there are other natural and artificial compounds that are sweet at much lower concentrations, allowing their use as non-caloric sugar substitutes. Examples of foods that may be used as non-sugar sweet substitutes include saccharin, aspartame, acesulfame potassium, sucralose, xylitol, erythritol, and stevia. Other compounds, such as miraculin, may alter perception of sweetness itself.

The chemosensory basis for detecting sweetness, which varies between both individuals and species, has only begun to be understood since the late 20th century. One theoretical model of sweetness is the multipoint attachment theory, which involves multiple binding sites between a sweetness receptor and a sweet substance.

Earth, Wind & Fire

Earth, Wind & Fire (EWF) is an American band that has spanned the musical genres of R&B, soul, funk, jazz, disco, pop, rock, Latin and African. They are one of the most successful bands of the 20th century. Rolling Stone Magazine described them as "innovative, precise yet sensual, calculated yet galvanizing" and declared that the band "changed the sound of black pop".

The band was founded in Chicago by Maurice White in 1969. Other members have included Philip Bailey, Verdine White, Ralph Johnson, Larry Dunn, Al McKay and Andrew Woolfolk. The band has received 20 Grammy nominations; they won six as a group and two of its members, Maurice White and Bailey, won separate individual awards. Earth, Wind & Fire have 12 American Music Awards nominations and four(20) awards. They have been inducted into the Rock and Roll Hall of Fame, the Vocal Group Hall of Fame, received a star on the Hollywood Walk of Fame, and sold over 100 million records, making them one of the world's best-selling bands of all time. Five members of Earth, Wind & Fire were also inducted into the Songwriters Hall of Fame: Maurice White, Philip Bailey, Verdine White, Larry Dunn and Al McKay. The music industry and fans have bestowed Lifetime Achievement honors from the American Society of Composers, Authors and Publishers (Rhythm & Soul Heritage Award – 2002), NAACP (Hall of Fame – 1994) and the BET Awards (Lifetime Achievement Award – 2002).

Christina Aguilera

Christina María Aguilera (born December 18, 1980) is an American singer-songwriter and actress. In the early 1990s, she appeared on television series Star Search and The Mickey Mouse Club. In 1998, Aguilera signed with RCA Records and recorded her self-titled debut album, which was released in 1999. The album was a commercial success in the United States, spawning three U.S. Billboard Hot 100 number-one singles—"Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby (All I Want Is You)", and helped Aguilera win the Grammy Award for Best New Artist. In 2000, RCA released Aguilera's Spanish-language album Mi Reflejo and holiday-theme album My Kind of Christmas. Her 2002 fourth studio album, Stripped, ventured into various genres including hip hop, Latin, and rock, and won a Grammy Award for Best Female Pop Vocal Performance for its second single "Beautiful".

Aguilera's 2006 fifth studio album, Back to Basics, was inspired by blues, soul, and jazz music of the 1920s-40s. The album peaked at number one on record charts of thirteen countries and won a Grammy Award for Best Female Pop Vocal Performance for its first single "Ain't No Other Man". In 2010, RCA released Aguilera's electronic-influenced album, Bionic, which failed to match the success of her previous albums; later that year, she starred in the film Burlesque. The following year, Aguilera was featured on Maroon 5's top-ten single "Moves like Jagger" and became an original coach on the U.S. television series The Voice, having since appeared on five of its nine seasons. Her 2012 seventh studio album, Lotus, became the lowest-selling album of her career. However, she later experienced rehabilitated commercial success in 2013, being featured on the top-ten singles "Feel This Moment" and "Say Something", which won a Grammy Award for Best Pop Duo/Group Performance.
