Black Lady
Black Lady is an American card game of the Hearts group for three to six players and the most popular of the group. It emerged in the early 20th century as an elaboration of Hearts and was initially also called Discard Hearts. It is named after its highest penalty card, the Queen of Spades or "Black Lady". It is a trick-avoidance game in which the aim is to avoid taking tricks containing hearts or the Black Lady. American author and leading bridge exponent, Ely Culbertson, describes it as "essentially Hearts with the addition of the queen of spades as a minus card, counting thirteen" and goes on to say that "Black Lady and its elaborations have completely overshadowed the original Hearts in popularity." The game is often called Hearts in America, although that is the proper name for the basic game in which only the cards of the heart suit incur penalty points. It is known by a variety of other names including American Hearts, Black Lady Hearts, Black Widow and Slippery Anne. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trick-avoidance
A trick-taking game is a card or tile-based game in which play of a ''hand'' centers on a series of finite rounds or units of play, called ''tricks'', which are each evaluated to determine a winner or ''taker'' of that trick. The object of such games then may be closely tied to the number of tricks taken, as in plain-trick games such as contract bridge, whist, and spades, or to the value of the cards contained in taken tricks, as in point-trick games such as pinochle, the tarot family, briscola, and most evasion games like hearts. Trick-and-draw games are trick-taking games in which the players can fill up their hands after each trick. In most variants, players are free to play any card into a trick in the first phase of the game, but must ''follow suit'' as soon as the stock is depleted. Trick-avoidance games like reversis or polignac are those in which the aim is to avoid taking some or all tricks. The domino game Texas 42 is an example of a trick-taking game that is not a ca ...

Standard 52-card Pack
The standard 52-card deck of French-suited playing cards is the most common pack of playing cards used today. In English-speaking countries it is the only traditional pack used for playing cards; in many countries of the world, however, it is used alongside other traditional, often older, standard packs with different suit systems such as those with German-, Italian-, Spanish- or Swiss suits. The most common pattern of French-suited cards worldwide and the only one commonly available in Britain and the United States is the English pattern pack. The second most common is the Belgian-Genoese pattern, designed in France, but whose use spread to Spain, Italy, the Ottoman Empire, the Balkans and much of North Africa and the Middle East.''Pattern Sheet 80'' at i-p-c-s.org.

Gong Zhu
Gong Zhu (拱猪) is a Chinese four-player trick-taking card game A trick-taking game is a card game, card or tile-based game in which play of a ''Hand (card games), hand'' centers on a series of finite rounds or units of play, called ''tricks'', which are each evaluated to determine a winner or ''taker'' of th ..., and is a Chinese version of the game Hearts. It differs from the standard Hearts game by assigning special point values to cards. The objective of the game is to score positive points and avoid penalty points. Gong Zhu means: ''Chase the Pig'', for "pig" is the name given to the Q♠. All players start with 0 points. The goal is to not be the first person to go past -1000 points (thus losing the game) and in some variations, also not more than 1000 points. The loser(s) becomes the pig, as ''Gong Zhu'' means "chase the pig" in Chinese. All points accumulate until any player(s) have lost, for which the game ends and all points will be reset to 0.

Absolute Value
In mathematics, the absolute value or modulus of a real number x, is the non-negative value without regard to its sign. Namely, , x, =x if is a positive number, and , x, =-x if x is negative (in which case negating x makes -x positive), and For example, the absolute value of 3 and the absolute value of −3 is The absolute value of a number may be thought of as its distance from zero. Generalisations of the absolute value for real numbers occur in a wide variety of mathematical settings. For example, an absolute value is also defined for the complex numbers, the quaternions, ordered rings, fields and vector spaces. The absolute value is closely related to the notions of magnitude, distance, and norm in various mathematical and physical contexts. Terminology and notation In 1806, Jean-Robert Argand introduced the term ''module'', meaning ''unit of measure'' in French, specifically for the ''complex'' absolute value,Oxford English Dictionary, Draft Revision, June 2008 an ...

Imaginary Unit
The imaginary unit or unit imaginary number () is a solution to the quadratic equation x^2+1=0. Although there is no real number with this property, can be used to extend the real numbers to what are called complex numbers, using addition and multiplication. A simple example of the use of in a complex number is 2+3i. Imaginary numbers are an important mathematical concept; they extend the real number system \mathbb to the complex number system \mathbb, in which at least one root for every nonconstant polynomial exists (see Algebraic closure and Fundamental theorem of algebra). Here, the term "imaginary" is used because there is no real number having a negative square. There are two complex square roots of −1: and -i, just as there are two complex square roots of every real number other than zero (which has one double square root). In contexts in which use of the letter is ambiguous or problematic, the letter or the Greek \iota is sometimes used instead. For example, ...

Complex Number
In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted , called the imaginary unit and satisfying the equation i^= -1; every complex number can be expressed in the form a + bi, where and are real numbers. Because no real number satisfies the above equation, was called an imaginary number by René Descartes. For the complex number a+bi, is called the , and is called the . The set of complex numbers is denoted by either of the symbols \mathbb C or . Despite the historical nomenclature "imaginary", complex numbers are regarded in the mathematical sciences as just as "real" as the real numbers and are fundamental in many aspects of the scientific description of the natural world. Complex numbers allow solutions to all polynomial equations, even those that have no solutions in real numbers. More precisely, the fundamental theorem of algebra asserts that every non-constant polynomial equation with real or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blue Moon
A blue moon is an additional full moon that appears in a subdivision of a year: the third of four full moons in a season. The phrase in modern usage has nothing to do with the actual color of the Moon, although a visually blue Moon (the Moon appearing with a bluish tinge) may occur under certain atmospheric conditions—for instance, if volcanic eruptions or fires release particles in the atmosphere of just the right size to preferentially scatter red light. Definition The term has traditionally, in the ''Maine Farmer's Almanac'', referred to an "extra" full moon, where a year which usually has 12 full moons has 13 instead. The "blue moon" reference is applied to the third full moon in a season with four full moons, thus correcting the timing of the last month of a season that would have otherwise been expected too early. This happens every two to three years (seven times in the Metonic cycle of 19 years). The author of a March 1946 article in ''Sky & Te ...

Pluto
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of trans-Neptunian object, bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is slightly less massive than Eris (dwarf planet), Eris. Like other Kuiper belt objects, Pluto is made primarily of ice and rock and is much smaller than the inner planets. Compared to Moon, Earth's moon, Pluto has only one sixth its mass and one third its volume. Pluto has a moderately orbital eccentricity, eccentric and inclined orbit, ranging from from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its average distance (). Pluto's eccentric orbit periodically brings it closer to the Sun than Neptune, but a stable orbital resonance prevents them from colliding. Pluto has moons of Pluto, five known moons: Charon (moon), Charon, the larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
