Sky

The sky (or celestial dome) is everything that lies above the surface of the Earth, including the atmosphere and outer space.

In the field of astronomy, the sky is also called the celestial sphere. This is viewed from Earth's surface as an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling. The celestial sphere is conventionally divided into regions called constellations. Usually, the term sky is used informally as the point of view from the Earth's surface; however, the meaning and usage can vary. In some cases, such as in discussing the weather, the sky refers to only the lower, more dense portions of the atmosphere.

During daylight, the sky appears to be blue because air scatters blue sunlight more than it scatters red. At night, the sky appears to be a mostly dark surface or region scattered with stars. During the day, the Sun can be seen in the sky unless obscured by clouds. In the night sky (and to some extent during the day) the moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning and precipitation can also be seen in the sky during storms. Birds, insects, aircraft, and kites are often considered to fly in the sky. Due to human activities, smog during the day and light pollution during the night are often seen above large cities.

Sky (building)

Sky (also known as 605 West 42nd Street) is a mixed-use building in Midtown Manhattan developed by the Moinian Group. The building was originally known as "Atelier II" due to its proximity to another Moinian rental, Atelier. The building contains residences and retail space. The building is one of two major developments by Moinian in the Special Hudson Yards District, the other being 3 Hudson Boulevard. At 656 ft., is the 59th tallest building in New York City.

History and construction

The Moinian Group purchased the site in 2005. It originally held a gas station and a parking facility. The project first broke ground in 2008, but construction was stalled due to the recession from 2009 until 2012, and the project was dubbed, like several nearby developments, a "zombie project" because Moinan retained ownership of the site but did not continue development. Activity resumed with a redesign by David Rockwell, replacing the original by Costas Kondylis. Construction began again in 2013, and was completed by the end of 2015.Tishman Realty & Construction was the firm responsible for the construction of the building.

Sky blue

Sky blue is the name of a color that resembles the color of the sky at noon. The entry for "sky-blue" in Murray's New English Dictionary (1919) reports a first sighting of the term in the article on "silver" in Ephraim Chambers's Cyclopaedia of 1728. However, many writers had used the term "sky blue" to name a color before Chambers. For example, we find "sky blue" in A Collection of Voyages and Travels (London: Awnsham and John Churchill, 1704), vol. 2, p. 322, where John Nieuhoff describes certain flowers: "they are of a lovely sky blue colour, and yellow in the middle". The sense of this color may have been first used in 1585 in a book by Nicolas De Nicolay where he stated "the tulbant of the merchant must be skie coloured".

Variations of sky blue

Celeste

Celeste (pronounced che-les-te in Italian se-lest in English) is the colloquial name for the pale turquoise blue colour associated with Italian bicycle manufacturer Bianchi S.p.A and sometimes known as Bianchi Green. In Italian, as the name indicates (Celestial), it is an attempt to reproduce the colour of clear skies. In English, this colour may also be referred to as Italian sky blue.

Eye

Eyes are the organs of vision. They detect light and convert it into electro-chemical impulses in neurons. In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods.

The simplest "eyes", such as those in microorganisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment and to the pretectal area to control the pupillary light reflex.

Eyes (video game)

Eyes is an arcade game released in 1982 by Rock-Ola.

Gameplay

The player controls a hat-wearing eyeball in a maze. As in Pac-Man the goal is to collect all of the dots to advance to next level, but in Eyes you shoot the dots rather than eat them. Computer-controlled eyes chase and shoot at the player. Shooting a computer eye gives points and removes it from the level, but it will reappear a short time later. Being shot by a computer eye is fatal.

As the game progresses, more computer eyes are added to levels and they take less time to shoot at the player. They also move faster.
