Memetics is a theory of the evolution of culture based on Darwinian principles with the meme as the unit of culture. The term "meme" was coined by biologist Richard Dawkins in his 1976 book The Selfish Gene, to illustrate the principle that he later called "Universal Darwinism". All evolutionary processes depend on information being copied, varied, and selected, a process also known as variation with selective retention. The information that is copied is called the replicator, and genes are the replicator for biological evolution. Dawkins proposed that the same process drives cultural evolution, and he called this second replicator the "meme". He gave as examples, tunes, catchphrases, fashions, and technologies. Like genes, memes are selfish replicators and have causal efficacy; in other words, their properties influence their chances of being copied and passed on. Some succeed because they are valuable or useful to their human hosts while others are more like viruses.

Just as genes can work together to form co-adapted gene complexes, so groups of memes acting together form co-adapted meme complexes or memeplexes. Memeplexes include (among many other things) languages, traditions, scientific theories, financial institutions, and religions. Dawkins famously referred to religions as "viruses of the mind".

Among proponents of memetics are psychologist Susan Blackmore, author of The Meme Machine, who argues that when our ancestors began imitating behaviours, they let loose a second replicator and co-evolved to become the "meme machines" that copy, vary, and select memes in culture. Philosopher Daniel Dennett develops memetics extensively, notably in his books Darwin's Dangerous Idea, and From Bacteria to Bach and Back. He describes the units of memes as "the smallest elements that replicate themselves with reliability and fecundity." and claims that "Human consciousness is itself a huge complex of memes." In The Beginning of Infinity, physicist David Deutsch contrasts static societies that depend on anti-rational memes suppressing innovation and creativity, with dynamic societies based on rational memes that encourage enlightenment values, scientific curiosity, and progress.

Criticisms of memetics include claims that memes do not exist, that the analogy with genes is false, that the units cannot be specified, that culture does not evolve through imitation, and that the sources of variation are intelligently designed rather than random. Critics of memetics include biologist Stephen Jay Gould who calls memetics a "meaningless metaphor". Philosopher Dan Sperber argues against memetics as a viable approach to cultural evolution because cultural items are not directly copied or imitated but are reproduced. Anthropologist Robert Boyd and biologist Peter Richerson work within the alternative, and more mainstream, field of cultural evolution theory and gene-culture coevolution. Dual inheritance theory has much in common with memetics but rejects the idea that memes are replicators. From this perspective, memetics is seen as just one of several approaches to cultural evolution and one that is generally considered less useful than the alternatives of gene-culture coevolution or dual inheritance theory. The main difference is that dual inheritance theory ultimately depends on biological advantage to genes, whereas memetics treats memes as a second replicator in its own right. Memetics also extends to the analysis of Internet culture and Internet memes.

The Nika riots (Greek: Στάσις τοῦ Νίκα, romanized: Stásis toû Níka), Nika revolt or Nika sedition took place against Byzantine emperor Justinian I in Constantinople over the course of a week in 532 C.E. They are often regarded as the most violent riots in the city's history, with nearly half of Constantinople being burned or destroyed and tens of thousands of people killed.

A mondegreen ( ) is a mishearing or misinterpretation of a phrase in a way that gives it a new meaning. Mondegreens are most often created by a person listening to a poem or a song; the listener, being unable to hear a lyric clearly, substitutes words that sound similar and make some kind of sense. The American writer Sylvia Wright coined the term in 1954, recalling a childhood memory of her mother reading the Scottish ballad "The Bonnie Earl o' Moray", and mishearing the words "laid him on the green" as "Lady Mondegreen".

"Mondegreen" was included in the 2000 edition of the Random House Webster's College Dictionary, and in the Oxford English Dictionary in 2002. Merriam-Webster's Collegiate Dictionary added the word in 2008.

In pipeline transportation, pigging is the practice of using devices known as pigs or scrapers to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline. These devices are known as pigs because they scrape or clean just like a normal pig.

These operations include but are not limited to cleaning and inspecting the pipeline. This is accomplished by inserting the pig into a "pig launcher" (or "launching station") — an oversized section in the pipeline, reducing to the normal diameter. The launching station is then closed and the pressure-driven flow of the product in the pipeline is used to push the pig along down the pipe until it reaches the receiving trap — the "pig catcher" (or "receiving station").

🔗 Computing 🔗 Computer science

Ousterhout's dichotomy is computer scientist John Ousterhout's categorization that high-level programming languages tend to fall into two groups, each with distinct properties and uses: system programming languages and scripting languages – compare programming in the large and programming in the small. This distinction underlies the design of his language Tcl.

System programming languages (or applications languages) usually have the following properties:

• They are typed statically
• They support creating complex data structures
• Programs in them are compiled into machine code
• Programs in them are meant to operate largely independently of other programs

System programming languages tend to be used for components and applications with large amounts of internal functionality such as operating systems, database servers, and Web browsers. These applications typically employ complex algorithms and data structures and require high performance. Prototypical examples of system programming languages include C and Modula-2.

By contrast, scripting languages (or glue languages) tend to have the following properties:

• They are typed dynamically
• They have little or no provision for complex data structures
• Programs in them (scripts) are interpreted

Scripting languages tend to be used for applications where most of the functionality comes from other programs (often implemented in system programming languages); the scripts are used to glue together other programs or add additional layers of functionality on top of existing programs. Ousterhout claims that scripts tend to be short and are often written by less sophisticated programmers, so execution efficiency is less important than simplicity and ease of interaction with other programs. Common applications for scripting include Web page generation, report generation, graphical user interfaces, and system administration. Prototypical examples of scripting languages include AppleScript, C shell, DOS batch files, and Tcl.

"Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo" is a grammatically correct sentence in American English, often presented as an example of how homonyms and homophones can be used to create complicated linguistic constructs through lexical ambiguity. It has been discussed in literature in various forms since 1967, when it appeared in Dmitri Borgmann's Beyond Language: Adventures in Word and Thought.

The sentence employs three distinct meanings of the word buffalo:

• as a proper noun to refer to a specific place named Buffalo, the city of Buffalo, New York, being the most notable;
• as a verb (uncommon in regular usage) to buffalo, meaning "to bully, harass, or intimidate" or "to baffle"; and
• as a noun to refer to the animal, bison (often called buffalo in North America). The plural is also buffalo.

An expanded form of the sentence which preserves the original word order is: "Buffalo bison, that other Buffalo bison bully, also bully Buffalo bison."

🔗 Automobiles 🔗 Cycling

The Twike (a portmanteau of the words twin and bike) is a human-electric hybrid vehicle (HEHV) designed to carry two passengers and cargo. Essentially a velomobile with an electrical hybrid engine, it can be driven in electric-only mode or electric + pedal power mode. Pedaling warms the user, making electric heating in winter unnecessary, extends the range of the vehicle but does not substantially add to the vehicle's top speed.

Constructed of lightweight materials such as aluminium (frame) and plastic (shell), the 246 kg (542 lb) (unladen, varying with battery weight) tricycle vehicle first used NiCd batteries, later Li-Mn, LiFePO₄ and LiIon. Typically ranges reach from 50 to over 500 km depending on battery size, type, status on one side and speed and altitude profile and load on the other. Energy is reclaimed while driving through regenerative braking, and load is removed from the electric system by use of the pedalling system which transfers its input directly to the drivetrain (i.e., both systems operate in parallel, not in series).

🔗 Linguistics

Oi is an interjection used in various varieties of the English language, particularly Australian English, British English, Indian English, Irish English, New Zealand English, and South African English, as well as non-English languages such as Chinese, Tagalog, Tamil, Hindi/Urdu, Japanese, and Portuguese to get the attention of another person or to express surprise or disapproval. It is sometimes used in Canadian English and very rarely in American English. The word is also common in the Indian subcontinent, where it has varied pronunciations of "O-ee" and "O-ye".

"Oi" has been particularly associated with working class and Cockney speech. It is effectively a local pronunciation of "hoy" (see H-dropping), an older expression. A study of the Cockney dialect in the 1950s found that whether it was being used to call attention or as a challenge depended on its tone and abruptness. The study's author noted that the expression is "jaunty and self-assertive" as well as "intensely cockney".

A poll of non-English speakers by the British Council in 2004 found that "oi" was considered the 61st most beautiful word in the English language. A spokesman commented that "Oi is not a word that I would've thought turned up in English manuals all that often." "Oi" was added to the list of acceptable words in US Scrabble in 2006.

Bourton-on-the-Water model village is a scale model village in the grounds of the Old New Inn in Bourton-on-the-Water, Gloucestershire, England. One of the first model villages in the country, it was started in 1936 and completed in 1940. The model represents the core of Bourton-on-the-Water as it appeared in 1936 in 1:9 scale. The model village contains around 100 buildings. It is open to the public and includes exhibitions of other models on smaller scales.

The Bourton-on-the-Water model village was one of the first to be built in England, being completed between 1936 and 1940. Possibly the only earlier example is the Bekonscot model village in Beaconsfield, Buckinghamshire, which is the oldest in the world, being begun in 1929, though not finished until the later 20th century. Bourton-on-the-Water was a fledgling tourist destination in the early 20th century and the landlord of the New Inn, Mr C A Morris, decided to build the model village to attract motorists to his public house. Morris had originally intended to convert the pub's vegetable garden into a village green with a stream with a waterfall and scale replicas of the arch bridges in the village. He soon decided to instead construct a 1:9 scale model of the entire village.

Morris and his wife carefully measured each building in the village and commissioned eight local craftsmen to construct scale replicas of around 100 structures. The craftsmen were construction workers rather than model makers so the methods used were scaled down versions of those used to construct real buildings. The walls are made from ashlars of local limestone, carefully cut to minimise joints and engraved to depict smaller courses of stone. The roofs are covered with slates of Cotswold stone from the Huntsman's Quarry located 3 miles (4.8 km) from the village. The drystone walls are real and have cock and hen or flatstone copings to correspond with the real walls in the village. Two of the buildings have full interiors, visible through perspex panels in their walls: the Church of England parish church of St Lawrence and the village's Baptist chapel. The church has intricate tracery windows and the windows on the models are glazed with real glass. The model village includes examples of 17th- to 19th-century Cotswold architecture. A recording of hymns being sung is played from the village's churches. The roads include model benches and post boxes. Miniature shrubs, including some bonsai trees planted in the 1930s, and pruned real trees represent the trees and bushes of the full-size village and alpine plants the flowers.

The model village covers the core of the historic village stretching from the Old Mill (now home to the Cotswold Motoring Museum) to the New Inn (which is now known as the Old New Inn). This includes High Street, Station Road, Moore Road, Victoria Street and Sherborne Street. The only building not shown in its correct relative position is St Lawrence's church, which would otherwise fall outside of the area covered. A running stream stands in for the River Windrush.

The model village includes a scale model of the model village (which would be at 1:81 scale). This model, in turn, contains a scale model of the model of the model village; being at 1:729 scale this measures around 1 foot (30 cm) in width. This model also contains a scale model (in paint only) of the model of the model of the model village (which would be at 1:6561 scale).

The model village opened to the public on 13 May 1937, as part of the celebrations for the coronation of George VI. The model village was the first tourist attraction in Bourton-on-the-Water; the village has since become one of the main tourist destinations in the Cotswolds. Construction of the models continued until 1940. No significant changes to the architecture have been made since, so the model village preserves Bourton-on-the-Water as it was in 1936, except that shop logos and window displays are updated to reflect changing occupants.

The Morris family maintained and operated the site until 1999 when the model village and the Old New Inn were sold to Julian and Vicki Atherton. In 2004 they purchased a collection of 30 miniature scenes that had been on display in a shop in the village; these form a separate exhibition. The model village became a grade II listed building on 22 March 2013, receiving the same protection as the early 18th-century Old New Inn, which was listed in 1983. In 2014 the Athertons bought a collection of seven 1:32 scale model buildings. These had been built by John Constable in Somerset, part funded by philanthropist Sir Paul Getty. They included a representation of Willy Lott's Cottage, the building depicted in John Constable's The Hay Wain. The collection, out of scale with the model village, were opened as a separate exhibition at the site. In 2016 when renovations were made to the roof of the St Lawrence's Church model, a penny dated 1937 was recovered, which is believed to indicate the date of its construction.

During the Athertons' ownership the village attracted around 100,000 visitors per year and was open every day except Christmas Day. The buildings remain outdoors all year round, while some model villages close in the winter when the models are put into storage. The Athertons employed a full time stone mason to repair damage caused by frost as well as three other employees to repaint the models and maintain the trees and bushes.

In April 2018 the Old New Inn and model village were put up for sale as the Athertons retired. The pub and model village were purchased by Andrew and Julie Lund-Yates, who had lived in Bourton-on-the-Water for 25 years.
