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.

The Sky (magazine)

The Sky was a magazine for amateur astronomers published between 1935 and 1941. It was the successor to a monthly bulletin called The Amateur Astronomer, which was published by the Amateur Astronomers Association (AAA) of New York City, and a precursor to Sky & Telescope before merging with The Telescope.

Cốm

Cốm, or green rice, is a dish in Vietnamese cuisine. It is not dyed green, as can be done with pandan, but is immature rice kernels roasted over very low heat then pounded in a mortar and pestle until flattened. Cốm is seasonal dish associated with autumn. It can be eaten plain or with coconut. The taste is slightly sweet with a nutty flavor.

A traditional pastry, bánh cốm (green rice cake) is made using cốm with mung bean filling. Cốm is often offered to worship the ancestors in the Mid Autumn Festival. The green rice can also be used in sweet soup, chè cốm. Cốm is similar to flat green rice of the Khmer people.

Guqin

The guqin (simplified/traditional: 古琴; pinyin: gǔqín; Wade–Giles ku-ch'in; pronounced [kùtɕʰǐn]; literally "ancient stringed instrument") is a plucked seven-string Chinese musical instrument of the zither family. It has been played since ancient times, and has traditionally been favoured by scholars and literati as an instrument of great subtlety and refinement, as highlighted by the quote "a gentleman does not part with his qin or se without good reason," as well as being associated with the ancient Chinese philosopher Confucius. It is sometimes referred to by the Chinese as "the father of Chinese music" or "the instrument of the sages". The guqin is not to be confused with the guzheng, another Chinese long zither also without frets, but with moveable bridges under each string.

Traditionally, the instrument was simply referred to as qin (Wade–Giles ch'in) but by the twentieth century the term had come to be applied to many other musical instruments as well: the yangqin hammered dulcimer, the huqin family of bowed string instruments, and the Western piano are examples of this usage. The prefix "gu-" (meaning "ancient") was later added for clarification. Thus, the instrument is called "guqin" today. It can also be called qixianqin (lit. "seven-stringed instrument"). Because Robert Hans van Gulik's famous book about the qin is called The Lore of the Chinese Lute, the guqin is sometimes inaccurately called a lute. Other incorrect classifications, mainly from music compact discs, include "harp" or "table-harp".
