Smile

A smile is a facial expression formed primarily by flexing the muscles at the sides of the mouth. Some smiles include a contraction of the muscles at the corner of the eyes, an action known as a "Duchenne smile". Smiles performed without the eye contraction can be perceived as "fake".

Among humans, smiling is an expression denoting pleasure, sociability, happiness, or amusement. It is distinct from a similar but usually involuntary expression of anxiety known as a grimace. Although cross-cultural studies have shown that smiling is a means of communication throughout the world, there are large differences between different cultures, with some using smiles to convey confusion or embarrassment.

Historical background

Primatologist Signe Preuschoft traces the smile back over 30 million years of evolution to a "fear grin" stemming from monkeys and apes who often used barely clenched teeth to portray to predators that they were harmless. The smile may have evolved differently among species and especially among humans. Apart from Biology as an academic discipline that interprets the smile, those who study kinesics and psychology such as Freitas-Magalhaes view the smile as an affect display that can communicate feelings such as love, happiness, pride, contempt, and embarrassment.

Smile! (novel)

Smile! is a children's book by Geraldine McCaughrean. In 2004 it won the Nestlé Smarties Book Prize Bronze Award.

Smile (The Beach Boys album)

Smile (occasionally typeset as SMiLE) was a projected album by American rock band the Beach Boys intended to follow their 11th studio album Pet Sounds. After the group's songwriting leader Brian Wilson abandoned large portions of music recorded between 1966 and 1967, the band recorded and released the dramatically scaled-down Smiley Smile album in its place. Some of the original Smile tracks eventually found their way onto subsequent Beach Boys studio and compilation albums. As more fans learned of the project's origins, details of its recordings acquired considerable mystique, and it was later acknowledged as the most legendary unreleased album in the history of popular music.

Working with lyricist Van Dyke Parks, Smile was composed as a multi-thematic concept album, existing today in its unfinished and fragmented state as an unordered series of abstract musical vignettes. Its genesis came during the recording of Pet Sounds, when Wilson began recording a new single: "Good Vibrations". The track was created by an unprecedented recording technique: over 90 hours of tape was recorded, spliced, and reduced into a three-minute pop song. It quickly became the band's biggest international hit yet; Smile was to be produced in a similar fashion. Wilson touted the album "a teenage symphony to God," incorporating a diverse range of music styles including psychedelic, doo-wop, barbershop singing, ragtime, yodeling, early American folk, classical music, and avant-garde explorations into noise and musical acoustics. Its projected singles were "Heroes and Villains", a Western musical comedy, and "Vega-Tables", a satire of physical fitness.

Pop (Gas album)

Pop is the final album by Wolfgang Voigt's Gas project, released on 28 March 2000 on Mille Plateaux. At the time of its release, reviews noted 'a striking left turn' in the sound, compared to other Gas releases; the album sounds considerably crisper, with a less muffled kickdrum and less of the 'underwater' quality present on other releases under the name. Like all Gas albums, the tracks are untitled.

Reception

Pop was named the sixth best album of the 2000s by Resident Advisor, and the 85th best of the decade by online magazine Pitchfork Media.

Stack (abstract data type)

In computer science, a stack is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and pop, which removes the most recently added element that was not yet removed. The order in which elements come off a stack gives rise to its alternative name, LIFO (for last in, first out). Additionally, a peek operation may give access to the top without modifying the stack.

The name "stack" for this type of structure comes from the analogy to a set of physical items stacked on top of each other, which makes it easy to take an item of the top of the stack, while getting to an item deeper in the stack may require taking off multiple other items first.

Considered as a linear data structure, or more abstractly a sequential collection, the push and pop operations occur only at one end of the structure, referred to as the top of the stack. This makes it possible to implement a stack as a singly linked list and a pointer to the top element.
