Equinox

An equinox is an astronomical event in which the plane of Earth's equator passes through the center of the Sun, making night and day of approximately equal length all over the planet. An equinox occurs twice each year, around 21 March and 23 September.

The equinoxes are the only times when the solar terminator (the "edge" between night and day) is perpendicular to the equator. As a result, the northern and southern hemispheres are equally illuminated.

In other words, the equinoxes are the only times when the subsolar point is on the equator, meaning that the Sun is exactly overhead at a point on the equatorial line. The subsolar point crosses the equator moving northward at the March equinox and southward at the September equinox.

The equinoxes, along with solstices, are directly related to the seasons of the year. In the northern hemisphere, the vernal equinox (March) conventionally marks the beginning of spring in most cultures and is considered the New Year in the Persian calendar, while the autumnal equinox (September) marks the beginning of autumn. In the southern hemisphere, the vernal equinox occurs in September and the autumnal equinox in March.

Ace

An ace is a playing card. In the standard French deck, an ace has a single suit symbol (a heart, diamond, spade, or club) located in the middle of the card, sometimes large and decorated, especially in the case of the Ace of Spades. This embellishment on the Ace of Spades started when King James VI of Scotland and I of England required an insignia of the printing house to be printed on the Ace of Spades. This insignia was necessary for identifying the printing house and stamping it as having paid the new stamp tax. Although this requirement was abolished in 1960, the tradition has been kept by many card makers. In other countries the stamp and embellishments are usually found on ace cards; clubs in France, diamonds in Russia, and hearts in Genoa because they have the most blank space.

The word "ace" comes from the Old French word as (from Latin 'as') meaning 'a unit', from the name of a small Roman coin. It originally meant the side of a die with only one mark, before it was a term for a playing card. Since this was the lowest roll of the die, it traditionally meant 'bad luck' in Middle English, but as the ace is often the highest playing card, its meaning has since changed to mean 'high-quality, excellence'. This connotation has seen the word applied to an unreachable tennis serve, a successful fighter pilot and more generally as a person proficient in his or her field, especially a sporting field.

Counter-Strike: Global Offensive

Counter-Strike: Global Offensive (CS:GO) is an online first-person shooter developed by Hidden Path Entertainment and Valve Corporation. It is the fourth game in the main Counter-Strike franchise. Counter-Strike: Global Offensive was released for Microsoft Windows, OS X, Xbox 360, and PlayStation 3 on August 21, 2012. The Linux version was released in September 2014. It features classic content, such as revamped versions of classic maps, as well as brand new maps, characters and game modes. Cross-platform multiplayer was planned between Windows, OS X, Linux, and PlayStation 3 players, but was ultimately limited to Windows, OS X, and Linux because of the differences in update-frequency between systems. The PlayStation 3 version offers three input control methods, which include using either the DualShock 3 controller, PlayStation Move or USB keyboard/mouse.

Gameplay

Like the previous games in the series, Global Offensive is an objective-based multiplayer first-person shooter. Each player joins either the Terrorist or Counter-Terrorist team and attempts to complete objectives or eliminate the enemy team. The game operates in short rounds that end when all players on one side are dead or a team's objective is completed. For most game modes, once a player dies, they must wait until the round ends to respawn.
