The Pale Blue Dot

In 1990, at the suggestion of astronomer Carl Sagan, NASA used the Voyager 1 space probe to take a picture of Earth as the probe was leaving the Solar System. From 3.7 billion miles away, the Earth appeared as a pale blue dot against the vastness of space, among bands of light reflected by the camera. During a lecture at Cornell University in 1994, Sagan shared his thoughts about the photograph and its larger implications:

"We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam. 
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. 
Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity – in all this vastness – there is no hint that help will come from elsewhere to save us from ourselves. It is up to us. It's been said that astronomy is a humbling, and I might add, a character-building experience. To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known."

Word of the Week 08/25/19: Plenipotentiary

From Merriam-Webster:
1. invested with full power
2. a person and especially a diplomatic agent invested with full power to transact business

The adjective plenipotentiary is typically used, as in our second example, after the noun it modifies in the ranking of diplomatic hierarchy. Plenipotentiary gets its power from its Latin roots: plenus, meaning "full," and potens, "powerful." When government leaders dispatch their ambassador plenipotentiary, minister plenipotentiary, or envoy plenipotentiary, they are not just sending an agent to deal with foreign affairs but one having full power to act on the behalf of his or her country and government. The word extraordinary is also found in titles of government representatives-sometimes in combination with plenipotentiary (as in "Ambassador Extraordinary and Plenipotentiary")-to denote an agent assigned to a particular (or extraordinary) diplomatic mission. Both the adjective and the noun plenipotentiary (meaning "a person invested with full power to transact business") appeared in the mid-17th century.

From Wikipedia:
Before the era of rapid international transport or essentially instantaneous communication (such as telegraph in the mid-19th century and then radio), diplomatic mission chiefs were granted full (plenipotentiary) powers to represent their government in negotiations with their host nation. Conventionally, any representations made or agreements reached with a plenipotentiary would be recognized and complied with by their government.

Historically, the common generic term for high diplomats of the crown or state was minister. It therefore became customary to style the chiefs of full ranking missions as Minister Plenipotentiary. This position was roughly equivalent to the modern Ambassador, a term that historically was reserved mainly for missions between the great powers and also relating to the dogal (city) state of Venice.

Permanent missions at a bilateral level were chiefly limited to relations between large, neighboring or closely allied powers, rarely to the very numerous small principalities, hardly worth the expense. However, diplomatic missions were dispatched for specific tasks, such as negotiating a treaty bilaterally, or via a conference, such as the Imperial Diet of the Holy Roman Empire. In such cases, it was normal to send a representative minister empowered to cast votes. For example, in the Peace Treaty of Versailles (1783), ending the American Revolution, John Adams, Benjamin Franklin and John Jay were named "minister plenipotentiary of the United States" to the Netherlands, France and Spain, respectively.

Word of the Week 08/18/19: Execrable

From Dictionary.com:
1. utterly detestable; abominable; abhorrent.

From Vocabulary.com:
1. unequivocally detestable
2. of very poor quality or condition
3. deserving a curse

From Lexico.com:
1. Extremely bad or unpleasant

From Merriam-Webster:
He or she who is cursed faces execrable conditions. Keep this in mind to remember that execrable is a descendant of the Latin verb exsecrari, meaning "to put under a curse." Since its earliest uses in English, beginning in the 14th century, execrable has meant "deserving or fit to be execrated," the reference being to things so abominable as to be worthy of formal denouncement (such as "execrable crimes"). But in the 19th century we lightened it up a bit, and our "indescribably bad" sense has since been applied to everything from roads ("execrable London pavement" - Sir Walter Scott) to food ("The coffee in the station house was ... execrable." - Clarence Day) to, inevitably, the weather ("the execrable weather of the past fortnight" - The (London) Evening Standard).

Word of the Week 08/04/19: Kingmaker

(in the context of game theory):

From Wikipedia:
A kingmaker scenario in a game of three or more players, is an endgame situation where a player who is unable to win has the capacity to determine which player among others will. Said player is referred to as the kingmaker or spoiler. No longer playing for themselves, they may make game decisions to favor a player who played more favorably (to them) earlier in the game. Except in games where interpersonal politics, by design, play a decisive role, this is undesirable.

Consider this simple game: Three gladiators play, with strengths 3, 4, 5. In turn, each gladiator must engage another, and they begin combat. The result of combat is that the weaker player is eliminated, and the stronger player loses strength equal to that of the weaker player. (For example, if "5" attacks "3", "3" will die and "5" will have strength 2.) The winning gladiator is the last one standing.

Each round of combat eliminates one gladiator, so there will be two rounds of combat. The first round of combat will eliminate one participant and weaken the other to a strength no greater than 2. The nonparticipant's strength is at least 3, so they are guaranteed to win the second round of combat, and the entire contest. Therefore, the game collapses: The winning gladiator is the one not involved in the first battle.

Hence, the gladiator whose turn comes first is the kingmaker. They must be involved in the first battle, hence cannot win, but with the liberty of choosing their opponent in that battle, can elect either of the other two players to be the winner of the contest.

Because they allow the outcome of the game to be determined by a player of (presumably) inferior strategy, kingmaker scenarios are usually considered undesirable, though to some extent they may be unavoidable in strategy games. Of course the argument can be made that this means the winner, chosen by the kingmaker, played with the additional restriction of not annoying the other players as much, presumably a more difficult task. In these games, the game mechanics, players' outcomes and strategies are often so interconnected that to eliminate all possibilities of this situation is almost impossible.

In tournament situations where for instance the first few teams proceed to the next round, a player that is already guaranteed to proceed can experience a situation similar to a kingmaker. They can sometimes influence who of the remaining players comes in second (when 2 players proceed). For such a player it can be profitable to make sure the weakest player proceeds, because this reduces his competition in subsequent rounds. This is often seen as undesirable because it conflicts with the concept that the strongest few are allowed to proceed to the next round.
