Walking (also known as ambulation) is one of the main gaits of locomotion among legged animals, and is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the number of limbs - even arthropods with six, eight or more limbs.

The word walk is descended from the Old English wealcan "to roll". In humans and other bipeds, walking is generally distinguished from running in that only one foot at a time leaves contact with the ground and there is a period of double-support. In contrast, running begins when both feet are off the ground with each step. This distinction has the status of a formal requirement in competitive walking events. For quadrupedal species, there are numerous gaits which may be termed walking or running, and distinctions based upon the presence or absence of a suspended phase or the number of feet in contact any time do not yield mechanically correct classification. The most effective method to distinguish walking from running is to measure the height of a person's center of mass using motion capture or a force plate at midstance. During walking, the center of mass reaches a maximum height at midstance while during running, it is at a minimum. Definitions based on the percent of the stride during which a foot is in contact with the ground (averaged across all feet) of greater than 50% contact corresponds well with identification of 'inverted pendulum' mechanics and are indicative of walking for animals with any number of limbs, although this definition is incomplete. Running humans and animals may have contact periods greater than 50% of a gait cycle when rounding corners, running uphill or carrying loads.

Kelly Maria Ripa (born October 2, 1970) is an American actress, talk show host, and television producer. Ripa, who played Hayley Vaughan on the television soap opera All My Children from 1990–2002, is best known as host of the popular syndicated morning talk show Live! with Kelly. Additionally, Ripa and her husband Mark Consuelos own a New York based production company, Milojo.

In 2012, The Hollywood Reporter named her one of the Most Powerful People in Media.

Ripa was born in Stratford, New Jersey, the daughter of Esther, a homemaker, and Joseph Ripa, a labor-union president and bus driver. She has a younger sister, Linda, who is a children's book author. She is of Italian and Irish descent. Her father has been the Democratic County Clerk for Camden County, New Jersey since June 2009. She is the first in her family to enter the acting profession. She has studied ballet since age three, plays the piano, and, in her words, is "no Barbra Streisand," but can carry a tune.

Ripa graduated from Eastern High School in Voorhees Township, New Jersey, where she became a cheerleader and was later encouraged by her drama teacher to pursue acting. "I owe so much of my career to Jim Beckley," she said. "He thought I was a natural performer and so he gave me the lead in the next show." She starred in local theatre productions and was discovered while performing in the comedy play The Ugly Duckling (c. 1941), by A.A. Milne, during her senior year. She attended Camden County College studying psychology, but dropped out and moved to New York City to be an actress.

Ludovico Einaudi OMRI (Italian pronunciation: [ludoˈviːko eiˈnaudi]) (born 23 November 1955 in Turin, Piedmont) is an Italian pianist and composer.

Einaudi was born in Turin, Italy. His mother played to him on the piano as a child. He began his musical training at the Conservatorio Verdi in Milan, gaining a diploma in composition in 1982. That same year, he studied with Luciano Berio and gained a scholarship to the Tanglewood Music Festival.

After studying at the Conservatory in Milan, and subsequently with Berio, he spent several years composing in traditional forms. In the mid-1980s he began to search for a more personal expression in a series of works for dance and multimedia, and later for piano. His music is ambient, meditative and often introspective, drawing on minimalism, world music, and contemporary pop. He has made a significant impact in the film world, with four international awards to his name.^{[citation needed]}

His father, Giulio Einaudi, was a publisher, and his grandfather, Luigi Einaudi, was President of Italy between 1948 and 1955. He currently resides on a vineyard in the Italian region of Piedmont.
