The Ford Nucleon is a concept car developed by Ford in 1957 designed as a future nuclear-powered car, one of a handful of such designs during the 1950s and '60s. The concept was only demonstrated as a scale model. The design did not include an internal-combustion engine; rather, the vehicle was to be powered by a small nuclear reactor in the rear of the vehicle, based on the assumption that this would one day be possible by reducing sizes. The car was to use a steam engine powered by uranium fission similar to those found in nuclear submarines.

The mock-up of the car can be viewed at the Henry Ford Museum in Dearborn, Michigan.

🔗 Statistics

Berkson's paradox also known as Berkson's bias or Berkson's fallacy is a result in conditional probability and statistics which is often found to be counterintuitive, and hence a veridical paradox. It is a complicating factor arising in statistical tests of proportions. Specifically, it arises when there is an ascertainment bias inherent in a study design. The effect is related to the explaining away phenomenon in Bayesian networks, and conditioning on a collider in graphical models.

It is often described in the fields of medical statistics or biostatistics, as in the original description of the problem by Joseph Berkson.

Mandaeism or Mandaeanism (Arabic: مَنْدَائِيَّة‎, Mandāʾīyah), also known as Sabaeanism (Arabic: صَابِئِيَّة‎, Ṣābiʾīyah), is a monotheistic and gnostic religion with a strongly dualistic cosmology. Its adherents, the Mandaeans, revere Adam, Abel, Seth, Enos, Noah, Shem, Aram, and especially John the Baptist. The Mandaeans have been counted among the Semites and speak a dialect of Eastern Aramaic known as Mandaic. The name 'Mandaean' is said to come from the Aramaic manda meaning "knowledge", as does Greek gnosis. Within the Middle East, but outside of their community, the Mandaeans are more commonly known as the Ṣubba (singular: Ṣubbī) or Sabians. The term Ṣubba is derived from the Aramaic root related to baptism, the neo-Mandaic is Ṣabi. In Islam, the "Sabians" (Arabic: الصَّابِئُون‎, aṣ-Ṣābiʾūn) are described several times in the Quran as People of the Book, alongside Jews and Christians. Occasionally, Mandaeans are called "Christians of Saint John".

According to most scholars, Mandaeaism originated sometime in the first three centuries AD, in either southwestern Mesopotamia or the Syro-Palestinian area. However, some scholars take the view that Mandaeanism is older and dates from pre-Christian times.

The religion has been practised primarily around the lower Karun, Euphrates and Tigris and the rivers that surround the Shatt-al-Arab waterway, part of southern Iraq and Khuzestan Province in Iran. There are thought to be between 60,000 and 70,000 Mandaeans worldwide. Until the Iraq War, almost all of them lived in Iraq. Many Mandaean Iraqis have since fled their country because of the turmoil created by the 2003 invasion of Iraq and subsequent occupation by U.S. armed forces, and the related rise in sectarian violence by Muslim extremists. By 2007, the population of Mandaeans in Iraq had fallen to approximately 5,000.

The Mandaeans have remained separate and intensely private. Reports of them and of their religion have come primarily from outsiders: particularly from Julius Heinrich Petermann, an Orientalist as well as from Nicolas Siouffi, a Syrian Christian who was the French vice-consul in Mosul in 1887, and British cultural anthropologist Lady E. S. Drower. There is an early if highly prejudiced account by the French traveller Jean-Baptiste Tavernier from the 1650s.

The year 1816 is known as the Year Without a Summer (also the Poverty Year and Eighteen Hundred and Froze To Death) because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.72–1.26 °F). This resulted in major food shortages across the Northern Hemisphere.

Evidence suggests that the anomaly was predominantly a volcanic winter event caused by the massive 1815 eruption of Mount Tambora in April in the Dutch East Indies (now Indonesia). This eruption was the largest eruption in at least 1,300 years (after the hypothesized eruption causing the extreme weather events of 535–536), and perhaps exacerbated by the 1814 eruption of Mayon in the Philippines.

Tilt! How to get bias into a Wikipedia article

To all you budding propagandists in Wikiland: too many of you are working like a bunch of amateurs. Sorry to be so negative, but you have to understand that getting bias into the Wikipedia is a skill; it requires practice, finesse and imagination. It has to be learned; it is not a natural thing, though some have more talent for it than others.

I have been following the Middle East Wikipedia battleground for a few years now, and have been very impressed with the skill of some editors in introducing bias into articles. To ingenuous editors, some of these techniques may seem innocuous enough; in many cases, it is hard to see how proposed edits are biasing an article one way or another. It is, in fact, only in the last few months that I have been able to define what these techniques are and how they work to introduce bias.

The first thing you need to know as a budding propagandist is this: there are two levels at which bias is introduced into the Wikipedia: at the article level, and at the topic level. You need to set your sights high: you don't want to merely bias a single article, you want the entire Wikipedia on your side. Without understanding the importance of topic bias, it is hard to understand many of the article-level techniques, so I will start with the topic level.

The person from Porlock was an unwelcome visitor to Samuel Taylor Coleridge during his composition of the poem Kubla Khan in 1797. Coleridge claimed to have perceived the entire course of the poem in a dream (possibly an opium-induced haze), but was interrupted by this visitor from Porlock while in the process of writing it. Kubla Khan, only 54 lines long, was never completed. Thus "person from Porlock", "man from Porlock", or just "Porlock" are literary allusions to unwanted intruders who disrupt inspired creativity.

🔗 Linguistics 🔗 Czech Republic 🔗 Slovakia 🔗 Linguistics/Phonetics

Strč prst skrz krk (pronounced [str̩tʃ pr̩st skr̩s kr̩k] (listen)) is a Czech and Slovak tongue-twister meaning "stick a finger through the throat".

The sentence is well known for being a semantically and syntactically valid clause without a single vowel, the nucleus of each syllable being a syllabic r, a common feature among many Slavic languages. It is often used as an example of such a phrase when learning Czech or Slovak as a foreign language.

In fact, both Czech and Slovak have two syllabic liquid consonants, the other being syllabic l. (There is also the syllabic bilabial nasal m in sedm in Czech.) As a result, there are plenty of words without vowels. Examples of long words of this type are scvrnkls, čtvrthrst, and čtvrtsmršť, the latter two being artificial occasionalisms.

There are other examples of vowelless sentences in Czech and Slovak, such as prd krt skrz drn, zprv zhlt hrst zrn, meaning "a mole farted through grass, having swallowed a handful of grains".

The longest Czech vowelless sentence (with 25 words and 82 consonants) as of 2013 is Škrt plch z mlh Brd pln skvrn z mrv prv hrd scvrnkl z brzd skrz trs chrp v krs vrb mls mrch srn čtvrthrst zrn. The meaning of the sentence is: Stingy dormouse from Brdy mountains fogs full of manure spots firstly proudly shrank a quarter of handful seeds, a delicacy for mean does, from brakes through bunch of Centaurea flowers into scrub of willows. IPA pronunciation of this sentence is [ʃkr̩t pl̩x zml̩x br̩t pl̩n skvr̩n zmr̩f pr̩f ɦr̩t st͡svrn̩kl̩ zbr̩st skr̩s tr̩s xr̩p fkr̩s vr̩p ml̩s mr̩x sr̩n t͡ʃtvrdɦr̩st zr̩n].

🔗 Software 🔗 Software/Computing

Maestro I was an early integrated development environment for software. developed by Softlab Munich in the 1970s and 1980s.

The system was originally called "Programm-Entwicklungs-Terminal-System" ("program development terminal system") abbreviated as PET; it was renamed after Commodore International introduced a home computer called the Commodore PET in 1977.

At one time there were 22,000 installations worldwide. The first USA installations were at Boeing in 1979, with eight Maestro I systems and Bank of America with 24 system and 576 developer terminals. Until 1989, there were 6,000 installations in the Federal Republic of Germany [1].

One of the last Maestro I systems is at the Museum of Information Technology at Arlington.

Thomas Harriot (Oxford, c. 1560 – London, 2 July 1621), also spelled Harriott, Hariot or Heriot, was an English astronomer, mathematician, ethnographer and translator who made advances within the scientific field. Thomas Harriot was recognized for his contributions in astronomy, mathematics, and navigational techniques. Harriot worked closely with John White to create advanced maps for navigation. While Harriot worked extensively on numerous papers on the subjects of astronomy, mathematics, and navigation the amount of work that was actually published was sparse. So sparse that the only publication that has been produced by Harriot was The Briefe and True Report of the New Found Land of Virginia. The premise of the book includes descriptions of English settlements and financial issues in Virginia at the time. He is sometimes credited with the introduction of the potato to the British Isles. Harriot was the first person to make a drawing of the Moon through a telescope, on 26 July 1609, over four months before Galileo Galilei.

After graduating from St Mary Hall, Oxford, Harriot travelled to the Americas, accompanying the 1585 expedition to Roanoke island funded by Sir Walter Raleigh and led by Sir Ralph Lane. Harriot was a vital member of the venture, having learned and translating the Carolina Algonquian language from two Native Americans: Wanchese and Manteo. On his return to England, he worked for the 9th Earl of Northumberland. At the Earl's house, he became a prolific mathematician and astronomer to whom the theory of refraction is attributed.

🔗 France

Flâneur (French: [flɑnœʁ]) is a French term popularized in the nineteenth-century for a type of urban male "stroller", "lounger", "saunterer", or "loafer". The word has some nuanced additional meanings (including as a loanword into English). Traditionally depicted as male, a flâneur is an ambivalent figure of urban affluence and modernity, representing the ability to wander detached from society with no other purpose than to be an acute observer of industrialized, contemporary life. Flânerie is the act of strolling, with all of its accompanying associations. A near-synonym of the noun is boulevardier.

The flâneur was first a literary type from 19th-century France, essential to any picture of the streets of Paris. The word carried a set of rich associations: the man of leisure, the idler, the urban explorer, the connoisseur of the street. However, the flâneur's origins are to be found in journalism of the Restoration, and the politics of post-revolutionary public space. Drawing on the work of Charles Baudelaire who described the flâneur in his poetry and 1863 essay "The Painter of Modern Life", Walter Benjamin promoted 20th-century scholarly interest in the flâneur as an emblematic archetype of urban, modern (even modernist) experience. Following Benjamin, the flâneur has become an important symbol for scholars, artists, and writers. The classic French female counterpart is the passante, dating to the works of Marcel Proust, though a 21st-century academic coinage is flâneuse, and some English-language writers simply apply the masculine flâneur also to women. The term has acquired an additional architecture and urban planning sense, referring to passers-by who experience incidental or intentional psychological effects from the design of a structure.
