In physics and mathematics, the dimension of a mathematical space is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it – for example, the point at 5 on a number line. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it – for example, both a latitude and longitude are required to locate a point on the surface of a sphere. The inside of a cube, a cylinder or a sphere is three-dimensional because three coordinates are needed to locate a point within these spaces.
In mathematics, a dynamical system is a system in which a function describes the time dependence of a point in a geometrical space. Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a pipe, and the number of fish each springtime in a lake.
An equinox is commonly regarded as the instant of time when the plane of Earth's equator passes through the center of the Sun. This occurs twice each year: around 20 March and 23 September. In other words, it is the moment at which the center of the visible Sun is directly above the Equator. In the northern hemisphere, the equinox in March is called the Vernal or Spring Equinox; the September equinox is called the Autumnal or Fall Equinox.
Longitude, is a geographic coordinate that specifies the east–west position of a point on the Earth's surface. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians connect points with the same longitude. By convention, one of these, the Prime Meridian, which passes through the Royal Observatory, Greenwich, England, was allocated the position of 0° longitude. The longitude of other places is measured as the angle east or west from the Prime Meridian, ranging from 0° at the Prime Meridian to +180° eastward and −180° westward. Specifically, it is the angle between a plane through the Prime Meridian and a plane through both poles and the location in question.
Right ascension is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the point above the earth in question.
When paired with declination, these astronomical coordinates specify the direction of a point on the celestial sphere in the equatorial coordinate system.
Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to maneuver the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.
The United States Military Academy (USMA), also known as West Point, Army, Army West Point, The Academy, or simply The Point, is a four-year federal service academy in West Point, New York. It was originally established as a fort that sits on strategic high ground overlooking the Hudson River with a scenic view, 50 miles (80 km) north of New York City. It is one of the four U.S. military service academies, and one of the five U.S. service academies.
An electric potential is the amount of work needed to move a unit of positive charge from a reference point to a specific point inside the field without producing an acceleration. Typically, the reference point is the Earth or a point at infinity, although any point beyond the influence of the electric field charge can be used.
Microsoft PowerPoint is a presentation program, created by Robert Gaskins and Dennis Austin at a software company named Forethought, Inc. It was released on April 20, 1987, initially for Macintosh computers only. Microsoft acquired PowerPoint for $14 million three months after it appeared. This was Microsoft's first significant acquisition, and Microsoft set up a new business unit for PowerPoint in Silicon Valley where Forethought had been located. Microsoft PowerPoint is one of many programs run by the company Microsoft and can be identified by its trademark orange, and P initial on the logo. It offers users many ways to display information from simple presentations to complex multimedia presentations.
Dirk Werner Nowitzki is a German professional basketball player for the Dallas Mavericks of the National Basketball Association (NBA). An alumnus of Röntgen Gymnasium and the DJK Würzburg basketball club, Nowitzki was chosen as the ninth pick in the 1998 NBA draft by the Milwaukee Bucks and was immediately traded to the Mavericks, where he has played ever since.
The point guard (PG), also called the one or point, is one of the five positions in a regulation basketball game. A point guard has perhaps the most specialized role of any position. Point guards are expected to run the team's offense by controlling the ball and making sure that it gets to the right player at the right time. Above all, the point guard must totally understand and accept their coach's game plan; in this way, the position can be compared to a quarterback in American football or a playmaker in association football (soccer). While the point guard must understand and accept the coach's gameplan, they must also be able to adapt to what the defense is allowing, and they also must control the pace of the game.
Gary Dwayne Payton Sr. is an American retired professional basketball player. He started at the point guard position. He is best known for his 13-year tenure with the Seattle SuperSonics, and holds Seattle franchise records in points, assists, and steals. He also played with the Milwaukee Bucks, Los Angeles Lakers, Boston Celtics and Miami Heat, the last with whom he won an NBA championship. He was nicknamed "The Glove" for his excellent defensive abilities. He was inducted into the Naismith Basketball Hall of Fame on September 8, 2013.
Walter Ray Allen Jr. is an American former professional basketball player. He played 18 seasons in the National Basketball Association (NBA) and was inducted into the Naismith Memorial Basketball Hall of Fame as a player in 2018.
Folsom points are a distinct form of knapped stone projectile points associated with the Folsom tradition of North America. The style of tool-making was named after the Folsom Site located in Folsom, New Mexico, where the first sample was found by George McJunkin within the bone structure of a bison in 1908. The Folsom point was identified as a unique style of projectile point in 1926.
A three-point field goal is a field goal in a basketball game made from beyond the three-point line, a designated arc surrounding the basket. A successful attempt is worth three points, in contrast to the two points awarded for field goals made within the three-point line and the one point for each made free throw.
UTC+03:00 is an identifier for a time offset from UTC of +03. In areas using this time offset, the time is three hours later than the Coordinated Universal Time (UTC).
Following the ISO 8601 standard, a time with this offset would be written as, for example, 2019-02-08T23:36:06+03:00.
UTC±00:00 is the following time:
The Celsius scale, also known as the centigrade scale, is a temperature scale used by the International System of Units (SI). As an SI derived unit, it is used by all countries except the United States, the Bahamas, Belize, the Cayman Islands and Liberia. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale. The degree Celsius (°C) can refer to a specific temperature on the Celsius scale or a unit to indicate a difference between two temperatures or an uncertainty. Before being renamed to honor Anders Celsius in 1948, the unit was called centigrade, from the Latin centum, which means 100, and gradus, which means steps.
The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. The kelvin is the base unit of temperature in the International System of Units (SI).
Two Point Hospital is a 2018 business simulation game developed by Two Point Studios and published by Sega for Linux, MacOS, and Microsoft Windows. A spiritual successor to Bullfrog Productions' 1997 game Theme Hospital, Two Point Hospital puts players in the role of a hospital administrator tasked with constructing and operating a hospital with the goal of curing patients of fictitious, comical ailments. The game was designed and developed by some of the creators of Theme Hospital, including Mark Webley and Gary Carr. They made use of their expertise in developing games such as Theme Hospital and Black & White and wanted players to be confident in using the menus. The use of humour was deemed important because visiting real hospitals is unpopular.
