A kleroterion (Ancient Greek: κληρωτήριον) was a randomization device used by the Athenian polis during the period of democracy to select citizens to the boule, to most state offices, to the nomothetai, and to court juries.

The kleroterion was a slab of stone incised with rows of slots and with an attached tube. Citizens' tokens—pinakia—were placed randomly in the slots so that every member of each of the tribes of Athens had their tokens placed in the same column. There was a pipe attached to the stone which could then be fed dice that were coloured differently (assumed to be black and white) and could be released individually by a mechanism that has not survived to posterity (but is speculated to be by two nails; one used to block the open end and another to separate the next die to fall from the rest of the dice above it). When a die was released, a complete row of tokens (so, one citizen from each of the tribes of Athens) was either selected if the die was coloured one colour, or discarded if it was the alternate colour. This process continued until the requisite number of citizens was selected.

The man or boy test was proposed by computer scientist Donald Knuth as a means of evaluating implementations of the ALGOL 60 programming language. The aim of the test was to distinguish compilers that correctly implemented "recursion and non-local references" from those that did not.

There are quite a few ALGOL60 translators in existence which have been designed to handle recursion and non-local references properly, and I thought perhaps a little test-program may be of value. Hence I have written the following simple routine, which may separate the man-compilers from the boy-compilers.

The Andreev Bay nuclear accident took place at Soviet naval base 569 in February 1982. Andreev Bay is a radioactive waste repository, located 55 km (34 mi) northwest of Murmansk and 60 km (37 mi) from the Norwegian border on the western shore of the Zapadnaya Litsa (Kola Peninsula). The repository entered service in 1961. In February 1982, a nuclear accident occurred in which radioactive water was released from a pool in building #5. Cleanup of the accident took place from 1983 to 1989. About 700,000 tonnes (770,000 tons) of highly radioactive water leaked into the Barents Sea during that time period. About 1,000 people took part in the cleanup effort. Vladimir Konstantinovich Bulygin, who was in charge of the naval fleet's radiation accidents, received the Hero of the Soviet Union distinction for his work.

The Boltzmann brain argument suggests that it is more likely for a single brain to spontaneously and briefly form in a void (complete with a false memory of having existed in our universe) than it is for our universe to have come about in the way modern science thinks it actually did. It was first proposed as a reductio ad absurdum response to Ludwig Boltzmann's early explanation for the low-entropy state of our universe.

In this physics thought experiment, a Boltzmann brain is a fully formed brain, complete with memories of a full human life in our universe, that arises due to extremely rare random fluctuations out of a state of thermodynamic equilibrium. Theoretically over a period of time on the order of hundreds of billions of years, by sheer chance atoms in a void could spontaneously come together in such a way as to assemble a functioning human brain. Like any brain in such circumstances, it would almost immediately stop functioning and begin to deteriorate.

The idea is ironically named after the Austrian physicist Ludwig Boltzmann (1844–1906), who in 1896 published a theory that tried to account for the fact that we find ourselves in a universe that is not as chaotic as the budding field of thermodynamics seemed to predict. He offered several explanations, one of them being that the universe, even one that is fully random (or at thermal equilibrium), would spontaneously fluctuate to a more ordered (or low-entropy) state. One criticism of this "Boltzmann universe" hypothesis is that the most common thermal fluctuations are as close to equilibrium overall as possible; thus, by any reasonable criterion, actual humans in the actual universe would be vastly less likely than "Boltzmann brains" existing alone in an empty universe.

Boltzmann brains gained new relevance around 2002, when some cosmologists started to become concerned that, in many existing theories about the Universe, human brains in the current Universe appear to be vastly outnumbered by Boltzmann brains in the future Universe who, by chance, have exactly the same perceptions that we do; this leads to the conclusion that statistically we ourselves are likely to be Boltzmann brains. Such a reductio ad absurdum argument is sometimes used to argue against certain theories of the Universe. When applied to more recent theories about the multiverse, Boltzmann brain arguments are part of the unsolved measure problem of cosmology. Boltzmann brains remain a thought experiment; physicists do not believe that we are actually Boltzmann brains, but rather use the thought experiment as a tool for evaluating competing scientific theories.

Grigori Yakovlevich Perelman (Russian: Григорий Яковлевич Перельман, IPA: [ɡrʲɪˈɡorʲɪj ˈjakəvlʲɪvʲɪtɕ pʲɪrʲɪlʲˈman] (listen); born 13 June 1966) is a Russian mathematician who is known for his contributions to the fields of geometric analysis, Riemannian geometry, and geometric topology.

In the 1990s, partly in collaboration with Yuri Burago, Mikhael Gromov, and Anton Petrunin, he made influential contributions to the study of Alexandrov spaces. In 1994, he proved the soul conjecture in Riemannian geometry, which had been an open problem for the previous 20 years. In 2002 and 2003, he developed new techniques in the analysis of Ricci flow, thereby providing a detailed sketch of a proof of the Poincaré conjecture and Thurston's geometrization conjecture, the former of which had been a famous open problem in mathematics for the past century. The full details of Perelman's work were filled in and explained by various authors over the following several years.

In August 2006, Perelman was offered the Fields Medal for "his contributions to geometry and his revolutionary insights into the analytical and geometric structure of the Ricci flow", but he declined the award, stating: "I'm not interested in money or fame; I don't want to be on display like an animal in a zoo." On 22 December 2006, the scientific journal Science recognized Perelman's proof of the Poincaré conjecture as the scientific "Breakthrough of the Year", the first such recognition in the area of mathematics.

On 18 March 2010, it was announced that he had met the criteria to receive the first Clay Millennium Prize for resolution of the Poincaré conjecture. On 1 July 2010, he rejected the prize of one million dollars, saying that he considered the decision of the board of the Clay Institute to be unfair, in that his contribution to solving the Poincaré conjecture was no greater than that of Richard S. Hamilton, the mathematician who pioneered the Ricci flow partly with the aim of attacking the conjecture. He had previously rejected the prestigious prize of the European Mathematical Society, in 1996.

The Gopher protocol is a communications protocol designed for distributing, searching, and retrieving documents in Internet Protocol networks. The design of the Gopher protocol and user interface is menu-driven, and presented an alternative to the World Wide Web in its early stages, but ultimately fell into disfavor, yielding to the Hypertext Transfer Protocol (HTTP). The Gopher ecosystem is often regarded as the effective predecessor of the World Wide Web.

The protocol was invented by a team led by Mark P. McCahill at the University of Minnesota. It offers some features not natively supported by the Web and imposes a much stronger hierarchy on the documents it stores. Its text menu interface is well-suited to computing environments that rely heavily on remote text-oriented computer terminals, which were still common at the time of its creation in 1991, and the simplicity of its protocol facilitated a wide variety of client implementations. More recent Gopher revisions and graphical clients added support for multimedia. Gopher was preferred by many network administrators for using fewer network resources than Web services.

Gopher's hierarchical structure provided a platform for the first large-scale electronic library connections. The Gopher protocol is still in use by enthusiasts, and although it has been almost entirely supplanted by the Web, a small population of actively-maintained servers remains.

Occasionally, even experienced Wikipedians lose their heads and devote every waking moment to edit warring over the most trivial thing, wasting time debating topics of no practical value, or wrestling over questions whose answers hold no practical consequence. This page documents our lamest examples. It isn't comprehensive or authoritative, but it serves as a showcase of situations where people lose sight of the big picture and obsessively expend huge amounts of energy fighting over something that, in the end, isn't really so important.

Edit warring is believed by some to be important, possibly due to the historical regularity and frequency of the occurrence of these wars. A careful and scholarly study of available archeological evidence has even suggested that edit wars may have recurred on a regular basis going back all the way to the beginning of recorded history, even before the advent of proper writing circa 2001 C.E. (see Wikipedia). In some earlier instances of edit warring, dating back from before the good old days, participants would simply utilize their swords and fight a battle, or later, their guns and fight a duel.

In modern times, physical combat has been outlawed and replaced by the careful inciting of personal attacks, strategic 3RR templating and canvassing, timely notices on WP:AN/I, and (in some cases) marking the changes as a minor edit. Truly, the revolutionary Wikipedia outlook has changed the way things get done. It has changed them from actually getting done to never getting done. On the other hand, nobody gets dispatched (so far!).

The Deseret alphabet ( (listen); Deseret: 𐐔𐐯𐑅𐐨𐑉𐐯𐐻 or 𐐔𐐯𐑆𐐲𐑉𐐯𐐻) is a phonemic English-language spelling reform developed between 1847 and 1854 by the board of regents of the University of Deseret under the leadership of Brigham Young, the second president of the Church of Jesus Christ of Latter-day Saints (LDS Church). George D. Watt is reported to have been the most actively involved in the development of the script,^: 159 as well as being its first serious user.^: 12

The Deseret alphabet was an outgrowth of the idealism and utopianism of Young and the early LDS Church. Young and the Mormon pioneers believed "all aspects of life" were in need of reform for the imminent millenniumand the Deseret alphabet was just one of many ways they sought to bring about a complete "transformation in society",^: 142 in anticipation of the Second Coming of Jesus. Young wrote of the reform that "it would represent every sound used in the construction of any known language; and, in fact, a step and partial return to a pure language which has been promised unto us in the latter days," the Adamic language spoken before the Tower of Babel.

In public statements, Young claimed the alphabet would replace the traditional Latin alphabet with an alternative, more phonetically accurate alphabet for the English language. This would offer immigrants an opportunity to learn to read and write English, he said, the orthography of which is often less phonetically consistent than those of many other languages.^: 65–66 Similar neographies have been attempted, the most well-known of which for English is the Shavian alphabet.

Young also prescribed the learning of Deseret to the school system, stating "It will be the means of introducing uniformity in our orthography, and the years that are now required to learn to read and spell can be devoted to other studies."

During the alphabet's heyday between 1854 and 1869, scriptural passages in newspapers, selected church records, a $5 gold coin, and occasional street signs and correspondence used the new letters. In 1868-9, after much difficulty creating suitable fonts, four books were printed: two school primers, the full Book of Mormon, and a portion of it titled the Book of Nephi.

Despite heavy and costly promotion by the early LDS Church, the alphabet never enjoyed prolonged widespread use and has been regarded by historians as a failure. However, in recent years, aided by digital typography, the Deseret Alphabet has been revived as a cultural heirloom.

A teasmade is a machine for making tea automatically, which was once common in the United Kingdom and some British Commonwealth countries. Teasmades generally include an analogue alarm clock and are designed to be used at the bedside, to ensure tea is ready first thing in the morning. Although crude versions existed in Victorian times, they only became practical with the availability of electric versions in the 1930s. They reached their peak in popularity in the 1960s and 1970s, since when their use has declined, but they are now enjoying a revival, partly as a retro novelty item.

The name teasmade is an example of a genericised trademark, now commonly used to refer to any automatic tea-making appliance.
