World championship

A world championship is generally an international sports competition open to elite competitors from across the world, representing their nations, and winning such an event will be considered the highest or near highest achievement in the sport or contest.

The title is usually awarded through a combination of specific contests or, less commonly, ranking systems (e.g. the ICC Test Championship), or a combination of the two (e.g. World Triathlon Championships in Triathlon). This determines a 'world champion', who or which is commonly considered the best nation, team, individual (or other entity) in the world in a particular field, although the vagaries of sport ensure that the competitor recognised at the best in an event is not always the 'world champion' (see Underdog).

Certain sports do not have a world championship, instead they may organise a world cup competition, or they may organize both. Often, the use of the term cup or championship in this sense is just a choice of words. Some sports have multiple champions because of multiple organizations such as mixed martial arts, boxing and wrestling.

World

World is a common name for the whole of human civilization, specifically human experience, history, or the human condition in general, worldwide, i.e. anywhere on Earth or pertaining to anywhere on Earth.

In a philosophical context it may refer to:

In a theological context, world usually refers to the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred. The "end of the world" refers to scenarios of the final end of human history, often in religious contexts.

World history is commonly understood as spanning the major geopolitical developments of about five millennia, from the first civilizations to the present.

World population is the sum of all human populations at any time; similarly, world economy is the sum of the economies of all societies (all countries), especially in the context of globalization. Terms like world championship, gross world product, world flags etc. also imply the sum or combination of all current-day sovereign states.

Championship

In sport, a championship is a competition in which the aim is to decide which individual or team is the champion.

Championship systems

Various forms of competition can be referred to by the term championship.

Title match system

In this system, a competitor has to challenge the current champion to win the championship. A competitor can challenge the current champion after defeating other challengers. This form of championship is used in wrestling, boxing, mixed martial arts and other combat sports.

Tournament system

The term championships (in the plural) is often used to refer to tournament competitions, either using a knockout format, such as at Wimbledon and other championships in tennis, or a mixed format with a group stage followed by knockout rounds, such as used in the European Football Championships.

A variation of the knockout format is the "best-of-X" or series format where two teams face each other for a specified number of times until one team wins the majority of specified games, most of the time the remaining games are not played anymore; only then is the losing team eliminated from contention and the winning team advances to the next level. This format is predominant in American sports such as baseball, ice hockey and basketball, and on test cricket.

Black operation

A black operation or black op is a covert operation by a government, a government agency, or a military organization. This can include activities by private companies or groups. Key features of a black operation are that it is secret and it is not attributable to the organization carrying it out. The main difference between a black operation and one that is merely secret is that a black operation involves a significant degree of deception, to conceal who is behind it or to make it appear that some other entity is responsible ("false flag" operations).

A single such activity may be called a "black bag operation"; that term is primarily used for covert or clandestine surreptitious entries into structures to obtain information for human intelligence operations. Such operations are known to have been carried out by the FBI, the Central Intelligence Agency,Mossad, MI6, ISI (Pakistan), RAW, MSS, and the intelligence services of other nations.

Etymology

"Black" may be used as a generic term for any government activity that is hidden or secret. For example, some activities by military and intel agencies are funded by a classified "black budget," of which the details, and sometimes even the total, are hidden from the public and from most congressional oversight.

Easter egg

Easter eggs, also called Paschal eggs, are decorated eggs that are often given to celebrate Easter or springtime. As such, Easter eggs are common during the season of Eastertide (Easter season). The oldest tradition is to use dyed and painted chicken eggs, but a modern custom is to substitute chocolate eggs, or plastic eggs filled with confectionery such as chocolate. Eggs, in general, were a traditional symbol of fertility, and rebirth.

History

The practice of decorating eggshells is ancient, predating Christian traditions. Ostrich eggs with engraved decoration that are 60,000 years old have been found in Africa. Decorated ostrich eggs, and representations of ostrich eggs in gold and silver, were commonly placed in graves of the ancient Sumerians and Egyptians as early as 5,000 years ago.

The Christian custom of the Easter egg, can be traced as far back as the early Christians of Mesopotamia, who stained eggs red in memory of the blood of Christ. The Christian Church officially adopted the custom, regarding the eggs as a symbol of the resurrection. The Roman Ritual, the first edition of which was published in 1610 but which contains texts of much older date, has among the Easter Blessings of Food, along with those for lamb, bread, and new produce, the following blessing for eggs:
