Common nightingale

The common nightingale or simply nightingale (Luscinia megarhynchos), also known as rufous nightingale, is a small passerine bird best known for its powerful and beautiful song. It was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It belongs to a group of more terrestrial species, often called chats.

Description

The common nightingale is slightly larger than the European robin, at 15–16.5 cm (5.9–6.5 in) length. It is plain brown above except for the reddish tail. It is buff to white below. Sexes are similar. The eastern subspecies L. m. hafizi and L. m. africana have paler upperparts and a stronger face-pattern, including a pale supercilium. The song of the nightingale has been described as one of the most beautiful sounds in nature, inspiring songs, fairy tales, opera, books, and a great deal of poetry.

Distribution and habitat

It is a migratory insectivorous species breeding in forest and scrub in Europe and south-west Asia, and wintering in west Africa. It is not found naturally in the Americas. The distribution is more southerly than the very closely related thrush nightingale Luscinia luscinia. It nests on or near the ground in dense vegetation. Research in Germany found that favoured breeding habitat of nightingales was defined by a number of geographical factors.

Nightingale (film)

Nightingale is a 2014 American drama film directed by Elliott Lester and written by Frederick Mensch. The film stars David Oyelowo. The film premiered on HBO on May 29, 2015.

Plot

The movie begins with Peter Snowden, a man in his late 30s, recording a video of his confession to murdering his mother. He explains that she was unwilling to allow him, an equal contributor to their household expenses, to have the house to himself for the purpose of entertaining an old military buddy. He goes on to explain that he feels no guilt for the crime but does regret the amount of blood. Peter appears to be a type of YouTube vlogger as he admonishes himself that he can not upload this video and shuts the camera off.

The next day Peter sits at the kitchen table singing happily and enjoying a bowl of what appears to be fruit loops. And as he heads off to work he seems to forget for a moment that the previous night he murdered his mother because he calls to her closed bedroom door to let her know he's leaving. His face registers the new reality.

Pitch contour

In linguistics, speech synthesis, and music, the pitch contour of a sound is a function or curve that tracks the perceived pitch of the sound over time.

Pitch contour may include multiple sounds utilizing many pitches, and can relate to frequency function at one point in time to the frequency function at a later point.

It is fundamental to the linguistic concept of tone, where the pitch or change in pitch of a speech unit over time affects the semantic meaning of a sound. It also indicates intonation in pitch accent languages.

One of the primary challenges in speech synthesis technology, particularly for Western languages, is to create a natural-sounding pitch contour for the utterance as a whole. Unnatural pitch contours result in synthesis that sounds "lifeless" or "emotionless" to human listeners, a feature that has become a stereotype of speech synthesis in popular culture.

In music, the pitch contour focuses on the relative change in pitch over time of a primary sequence of played notes. The same contour can be transposed without losing its essential relative qualities, such as sudden changes in pitch or a pitch that rises or falls over time.

Contour (linguistics)

In phonetics, contour describes speech sounds which behave as single segments, but which make an internal transition from one quality, place, or manner to another. These sounds may be tones, vowels, or consonants.

Many tone languages have contour tones, which move from one level to another. For example, Mandarin Chinese has four lexical tones. The high tone is level, without contour; the falling tone is a contour from high pitch to low; the rising tone a contour from mid pitch to high, and, when spoken in isolation, the low tone takes on a dipping contour, mid to low and then to high pitch. These are transcribed with series of either diacritics or tone letters, which with proper font support fuse into an iconic shape: [ma˨˩˦].

In the case of vowels, the word diphthong is used instead of 'contour'. These are vowels that glide from one place of articulation to another, as in English boy and bow. These are officially transcribed with a non-syllabic sign under one of the vowel letters: [bɔɪ̯], [baʊ̯], though when there is no chance of confusion, the diacritic is often left off for simplicity.

CONTOUR

The COmet Nucleus TOUR (CONTOUR) was a NASA Discovery-class space probe that failed shortly after its July 2002 launch. It had as its primary objective close flybys of two comet nuclei with the possibility of a flyby of a third known comet or an as-yet-undiscovered comet.

The two comets scheduled to be visited were Encke and Schwassmann-Wachmann-3, and the third target was d'Arrest. It was hoped that a new comet would have been discovered in the inner Solar System between 2006 and 2008, in which case the spacecraft trajectory would have been changed if possible to rendezvous with the new comet. Scientific objectives included imaging the nuclei at resolutions of up to 4 meters (13 ft), performing spectral mapping of the nuclei at resolutions of up to 100 meters (330 ft), and obtaining detailed compositional data on gas and dust in the near-nucleus environment, with the goal of improving knowledge of the characteristics of comet nuclei.

After the solid rocket motor intended to inject the spacecraft into solar orbit was ignited on August 15, 2002, contact with the probe could not be re-established. Ground-based telescopes later found three objects along the course of the satellite, leading to the speculation that it had disintegrated. Attempts to contact the probe were ended on December 20, 2002. The probe thus accomplished none of its primary scientific objectives, but did prove some spaceflight technologies, such as the APL-developed non-coherent spacecraft navigation technique, which was later used on the New Horizons spacecraft.
