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.

List of Gurren Lagann characters

This is a list of primary characters from the anime series Tengen Toppa Gurren Lagann. Most of them are people who became the first members of Kamina's Team Gurren. The plot of Tengen Toppa Gurren Lagann is divided into two main story arcs, separated by a seven-year timeskip. After the timeskip, most characters pass through important changes in their appearances and/or personalities, and some of them have their own unique roles in the overall story.

Simon

Personal Gunmen

The series protagonist, Simon (pronounced as See-mon) originally started off as a boy in the beginning of the story who suffered a low self-esteem due to his lack of parents and fear of earthquakes. Though physically underdeveloped for his age and ignored by adults and snubbed by girls, Simon is a valued digger in Giha Village. Simon is eventually befriended by Kamina, whose inspirational speeches start to give him enough confidence to muster his courage and take action in bouts of intense determination. Finding Lagann during his dig, Simon joins Kamina in going to the surface where he develops a crush on Yoko before learning she has feelings for Kamina. When Kamina died during the formation of Team Dai-Gurren, Simon is thrown into a maddened and pervasive depression, driving him to be overly aggressive in combat while isolating himself among the Team. But Simon's meeting with Nia helps him come to a revelation about his own nature, leading to him discarding his fears and doubts as he takes over Kamina's role as Team Dai-Gurren's leader.

Simon (cipher)

Simon is a family of lightweight block ciphers publicly released by the National Security Agency (NSA) in June 2013. Simon has been optimized for performance in hardware implementations, while its sister algorithm, Speck, has been optimized for software implementations.

Description of the cipher

The Simon block cipher is a balanced Feistel cipher with an n-bit word, and therefore the block length is 2n. The key length is a multiple of n by 2, 3, or 4, which is the value m. Therefore, a Simon cipher implementation is denoted as Simon2n/nm. For example, Simon64/128 refers to the cipher operating on a 64-bit plaintext block (n=32) that uses a 128-bit key. The block component of the cipher is uniform between the Simon implementations; however, the key generation logic is dependent on the implementation of 2, 3 or 4 keys.

Simon supports the following combinations of block sizes, key sizes and number of rounds:
