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.

Felix Baumgartner

Felix Baumgartner (German: [ˈfeː.lɪks ˈba͡ʊ̯mˌɡaɐ̯t.nɐ]; born 20 April 1969) is an Austrian skydiver, daredevil and BASE jumper. He is best known for his participation in the Red Bull Stratos project, in which he jumped to Earth from a helium balloon in the stratosphere on October 14, 2012. Doing so, he set world records for skydiving an estimated 39 km (24 mi), reaching an estimated speed of 1,357.64 km/h (843.6 mph), or Mach 1.25, . He became the first person to break the sound barrier without vehicular power relative to the surface on his descent. He broke skydiving records for exit altitude, vertical freefall distance without drogue, and vertical speed without drogue. Though he still holds the latter records, the first was broken two years later, when on 24 October 2014, Alan Eustace jumped from 135,890 feet - or, 41.42 km (25.74 mi) with a drogue.

Baumgartner is also renowned for the particularly dangerous nature of the stunts he has performed during his career. Baumgartner spent time in the Austrian military where he practiced parachute jumping, including training to land on small target zones.

Red Bull Stratos

Red Bull Stratos was a space diving project involving Austrian skydiver Felix Baumgartner. On 14 October 2012, Baumgartner flew approximately 39 kilometres (24 mi) into the stratosphere over New Mexico, United States, in a helium balloon before free falling in a pressure suit and then parachuting to Earth. The total jump, from leaving the capsule to landing on the ground, lasted approximately ten minutes. While the free fall was initially expected to last between five and six minutes, Baumgartner deployed his parachute after 4 minutes and 19 seconds.

Reaching 1,357.64 km/h (843.6 mph)—Mach 1.25—Baumgartner broke the sound barrier on his descent, thus becoming the first human to do so without any form of engine power. Measurements show Baumgartner also broke two other world records. With a final altitude of 38,969 m (127,851 ft) (23.3884 miles), Baumgartner broke the unofficial record for the highest manned balloon flight of 37,640 m (123,491 ft) previously set by Nicholas Piantanida. He also broke the record for the highest altitude jump, set in 1960 by retired USAF Colonel Joseph Kittinger, who was Baumgartner's mentor and capsule communicator at mission control. These claims were verified by the Fédération Aéronautique Internationale (FAI).

Free fall

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it and moves along a geodesic. The present article only concerns itself with free fall in the Newtonian domain.

An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. An object moving upwards would not normally be considered to be falling, but if it is subject to the force of gravity only, it is said to be in free fall. The moon is thus in free fall.

In a uniform gravitational field, in the absence of any other forces, gravitation acts on each part of the body equally and this is weightlessness, a condition that also occurs when the gravitational field is zero (such as when far away from any gravitating body). A body in free fall experiences "0 g".

The term "free fall" is often used more loosely than in the strict sense defined above. Thus, falling through an atmosphere without a deployed parachute, or lifting device, is also often referred to as free fall. The aerodynamic drag forces in such situations prevent them from producing full weightlessness, and thus a skydiver's "free fall" after reaching terminal velocity produces the sensation of the body's weight being supported on a cushion of air.

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").
