Data

Data (/ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) is a set of values of qualitative or quantitative variables; restated, pieces of data are individual pieces of information. Data is measured, collected and reported, and analyzed, whereupon it can be visualized using graphs or images. Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing.

Raw data, i.e. unprocessed data, is a collection of numbers, characters; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data is raw data that is collected in an uncontrolled in situ environment. Experimental data is data that is generated within the context of a scientific investigation by observation and recording.

The Latin word "data" is the plural of "datum", and still may be used as a plural noun in this sense. Nowadays, though, "data" is most commonly used in the singular, as a mass noun (like "information", "sand" or "rain").

Astronaut

An astronaut or cosmonaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. Although generally reserved for professional space travelers, the terms are sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists.

Starting in the 1950s up to 2002, astronauts were sponsored and trained exclusively by governments, either by the military or by civilian space agencies. With the suborbital flight of the privately funded SpaceShipOne in 2004, a new category of astronaut was created: the commercial astronaut.

Definition

The criteria for what constitutes human spaceflight vary. The Fédération Aéronautique Internationale (FAI) Sporting Code for astronautics recognizes only flights that exceed an altitude of 100 kilometers (62 mi). In the United States, professional, military, and commercial astronauts who travel above an altitude of 50 miles (80 km) are awarded astronaut wings.

Dream

Dreams are successions of images, ideas, emotions, and sensations that occur usually involuntarily in the mind during certain stages of sleep. The content and purpose of dreams are not definitively understood, though they have been a topic of scientific speculation, as well as a subject of philosophical and religious interest, throughout recorded history. The scientific study of dreams is called oneirology.

Dreams mainly occur in the rapid-eye movement (REM) stage of sleep—when brain activity is high and resembles that of being awake. REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However, these dreams tend to be much less vivid or memorable.

The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes. People are more likely to remember the dream if they are awakened during the REM phase. The average person has three to five dreams per night, and some may have up to seven; however, most dreams are immediately or quickly forgotten. Dreams tend to last longer as the night progresses. During a full eight-hour night sleep, most dreams occur in the typical two hours of REM.

Yuri Gagarin

Yuri Alekseyevich Gagarin (Russian: Ю́рий Алексе́евич Гага́рин; IPA: [ˈjʉrʲɪj ɐlʲɪˈksʲejɪvʲɪtɕ ɡɐˈɡarʲɪn]; 9 March 1934 – 27 March 1968) was a Russian Soviet pilot and cosmonaut. He was the first human to journey into outer space, when his Vostok spacecraft completed an orbit of the Earth on 12 April 1961.

Gagarin became an international celebrity, and was awarded many medals and titles, including Hero of the Soviet Union, the nation's highest honour. Vostok 1 marked his only spaceflight, but he served as backup crew to the Soyuz 1 mission (which ended in a fatal crash). Gagarin later became deputy training director of the Cosmonaut Training Centre outside Moscow, which was later named after him. Gagarin died in 1968 when the MiG-15 training jet he was piloting crashed. The Yuri Gagarin Medal is awarded in his honor.

Early life and education

Yuri Gagarin was born in the village of Klushino, near Gzhatsk (renamed Gagarin in 1968 after his death), on 9 March 1934. His parents worked on a collective farm: Alexey Ivanovich Gagarin as a carpenter and bricklayer, and Anna Timofeyevna Gagarina as a milkmaid. Yuri was the third of four children: older brother Valentin, older sister Zoya, and younger brother Boris.

Red Bull

Red Bull is an energy drink sold by Austrian company Red Bull GmbH, created in 1987. In terms of market share, Red Bull is the highest-selling energy drink in the world, with 5.387 billion cans sold in 2013.

Austrian entrepreneur Dietrich Mateschitz was inspired by an existing energy drink named Krating Daeng, which was first invented and sold in Thailand. He took this idea, modified the ingredients to suit the tastes of Westerners, and, in partnership with Chaleo Yoovidhya, founded Red Bull GmbH in 1987 in Chakkapong, Thailand. In Thai, daeng means red, and krating is the large bovine called "gaur". Red Bull is sold in a tall and slim blue-silver can, while Krating Daeng is in a gold shorter can. The two are different products, produced separately.

The Red Bull company slogan is "Red Bull gives you wings", and the product is marketed through advertising, events (Red Bull Cliff Diving World Series, Red Bull Air Race, Red Bull Crashed Ice), sports team ownerships (RB Leipzig, FC Red Bull Salzburg, Red Bull Brasil, New York Red Bulls, Red Bull Racing, Scuderia Toro Rosso), celebrity endorsements, and music, through its record label Red Bull Records.
