๐Ÿ”— Rain Follows the Plow

๐Ÿ”— Australia ๐Ÿ”— United States History ๐Ÿ”— Australia/Australian history ๐Ÿ”— Australia/South Australia

Rain follows the plow is the conventional name for a now-discredited theory of climatology that was popular throughout the American West and Australia during the late 19th century. The phrase was employed as a summation of the theory by Charles Dana Wilber:

God speed the plow. ... By this wonderful provision, which is only man's mastery over nature, the clouds are dispensing copious rains ... [the plow] is the instrument which separates civilization from savagery; and converts a desert into a farm or garden. ... To be more concise, Rain follows the plow.

The basic premise of the theory was that human habitation and agriculture through homesteading effected a permanent change in the climate of arid and semi-arid regions, making these regions more humid. The theory was widely promoted in the 1870s as a justification for the settlement of the Great Plains, a region previously known as the "Great American Desert". It was also used to justify the expansion of wheat growing on marginal land in South Australia during the same period.

According to the theory, increased human settlement in the region and cultivation of soil would result in an increased rainfall over time, rendering the land more fertile and lush as the population increased. As later historical records of rainfall indicated, the theory was based on faulty evidence arising from brief climatological fluctuations that happened to coincide with settlement, an example of the logical fallacy that correlation means causation. The theory was later refuted by climatologists and is now definitively regarded as pure superstition.

๐Ÿ”— One red paperclip

๐Ÿ”— Internet culture

One red paperclip is a website created by Canadian blogger Kyle MacDonald, who bartered his way from a single red paperclip to a house in a series of fourteen online trades over the course of a year. MacDonald was inspired by the childhood game Bigger, Better. His site received a considerable amount of notice for tracking the transactions. "A lot of people have been asking how I've stirred up so much publicity around the project, and my simple answer is: 'I have no idea'", he told the BBC.

๐Ÿ”— Japanese Aesthetics

๐Ÿ”— Philosophy ๐Ÿ”— Philosophy/Aesthetics ๐Ÿ”— Japan ๐Ÿ”— Japan/Culture

Japanese aesthetics comprise a set of ancient ideals that include wabi (transient and stark beauty), sabi (the beauty of natural patina and aging), and yลซgen (profound grace and subtlety). These ideals, and others, underpin much of Japanese cultural and aesthetic norms on what is considered tasteful or beautiful. Thus, while seen as a philosophy in Western societies, the concept of aesthetics in Japan is seen as an integral part of daily life. Japanese aesthetics now encompass a variety of ideals; some of these are traditional while others are modern and sometimes influenced by other cultures.

๐Ÿ”— The Origin of Consciousness in the Breakdown of the Bicameral Mind (1976)

๐Ÿ”— Books ๐Ÿ”— Psychology

The Origin of Consciousness in the Breakdown of the Bicameral Mind is the 1976 book by the Princeton psychologist, psychohistorian and consciousness theorist Julian Jaynes (1920-1997). The book addresses the problematic nature of consciousness โ€“ โ€œthe ability to introspectโ€ โ€“ which in Jaynesโ€™s view must be distinguished from sensory awareness and other processes of cognition. Jaynes presents his proposed solution: that consciousness is a โ€œlearned behaviorโ€ based more on language and culture than on biology; this solution, in turn, points to the origin of consciousness in ancient human history rather than in metaphysical or evolutionary processes; furthermore, archaeological and historical evidence indicates that prior to the โ€œlearningโ€ of consciousness, human mentality was what Jaynes called "the bicameral mind" โ€“ a mentality based on verbal hallucination.

The first edition was released in January 1977 in English. Two later editions, in 1982 and in 1990, were released by Jaynes with additions but without alterations. It was Jaynes's only book, and it is still in print, in several languages. In addition to numerous reviews and commentaries, there are several summaries of the book's material, for example, in the journal Behavioral and Brain Sciences, in lectures and discussions published in Canadian Psychology, and in Art/World.

The Scottish Cafรฉ (Polish: Kawiarnia Szkocka) was a cafรฉ in Lwรณw, Poland (now Lviv, Ukraine) where, in the 1930s and 1940s, mathematicians from the Lwรณw School of Mathematics collaboratively discussed research problems, particularly in functional analysis and topology.

Stanislaw Ulam recounts that the tables of the cafรฉ had marble tops, so they could write in pencil, directly on the table, during their discussions. To keep the results from being lost, and after becoming annoyed with their writing directly on the table tops, Stefan Banach's wife provided the mathematicians with a large notebook, which was used for writing the problems and answers and eventually became known as the Scottish Book. The bookโ€”a collection of solved, unsolved, and even probably unsolvable problemsโ€”could be borrowed by any of the guests of the cafรฉ. Solving any of the problems was rewarded with prizes, with the most difficult and challenging problems having expensive prizes (during the Great Depression and on the eve of World War II), such as a bottle of fine brandy.

For problem 153, which was later recognized as being closely related to Stefan Banach's "basis problem", Stanisล‚aw Mazur offered the prize of a live goose. This problem was solved only in 1972 by Per Enflo, who was presented with the live goose in a ceremony that was broadcast throughout Poland.

The cafรฉ building now houses the Szkocka Restaurant & Bar (named for the original Scottish Cafรฉ) and the Atlas Deluxe hotel at the street address of 27 Taras Shevchenko Prospekt.

๐Ÿ”— Pournelle's Iron Law of Bureaucracy

๐Ÿ”— Biography ๐Ÿ”— Science Fiction ๐Ÿ”— Biography/arts and entertainment ๐Ÿ”— Journalism

Jerry Eugene Pournelle (; August 7, 1933 โ€“ September 8, 2017) was an American polymath: scientist in the area of operations research and human factors research, science fiction writer, essayist, journalist, and one of the first bloggers. In the 1960s and early 1970s, he worked in the aerospace industry, but eventually focused on his writing career. In an obituary in gizmodo, he is described as "a tireless ambassador for the future."

Pournelle is particularly known for writing hard science fiction, and received multiple awards for his writing. In addition to his solo writing, he wrote several novels with collaborators, most notably Larry Niven. Pournelle served a term as President of the Science Fiction and Fantasy Writers of America.

Pournelle's journalism focused primarily on the computer industry, astronomy, and space exploration. From the 1970s until the early 1990s, he contributed to the computer magazine Byte, writing from the viewpoint of an intelligent user, with the oft-cited credo, โ€œWe do this stuff so you wonโ€™t have to.โ€ He created one of the first blogs, entitled "Chaos Manor", which included commentary about politics, computer technology, space technology, and science fiction.

Pournelle was also known for his paleoconservative political views, which were sometimes expressed in his fiction. He was one of the founders of the Citizens' Advisory Council on National Space Policy, which developed some of the Reagan Administration's space initiatives, including the earliest versions of what would become the Strategic Defense Initiative.

๐Ÿ”— Antifuse, the opposite of a fuse

๐Ÿ”— Electronics

An antifuse is an electrical device that performs the opposite function to a fuse. Whereas a fuse starts with a low resistance and is designed to permanently break an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance, and programming it converts it into a permanent electrically conductive path (typically when the voltage across the antifuse exceeds a certain level). This technology has many applications.

๐Ÿ”— IKEA Effect

๐Ÿ”— Philosophy ๐Ÿ”— Psychology

The IKEA effect is a cognitive bias in which consumers place a disproportionately high value on products they partially created. The name derives from the name of Swedish manufacturer and furniture retailer IKEA, which sells many furniture products that require assembly.

The IKEA effect has been described as follows: "The price is low for IKEA products largely because they take labor out of the equation. With a Phillips screwdriver, an Allen wrench and rubber mallet, IKEA customers can very literally build an entire home's worth of furniture on a very tight budget. But what happens when they do?" They "fall in love with their IKEA creations. Even when there are parts missing and the items are incorrectly built, customers in the IKEA study still loved the fruits of their labors."

๐Ÿ”— Gรถdel's Completeness Theorem

๐Ÿ”— Mathematics

Gรถdel's completeness theorem is a fundamental theorem in mathematical logic that establishes a correspondence between semantic truth and syntactic provability in first-order logic. It makes a close link between model theory that deals with what is true in different models, and proof theory that studies what can be formally proven in particular formal systems.

It was first proved by Kurt Gรถdel in 1929. It was then simplified in 1947, when Leon Henkin observed in his Ph.D. thesis that the hard part of the proof can be presented as the Model Existence Theorem (published in 1949). Henkin's proof was simplified by Gisbert Hasenjaeger in 1953.

๐Ÿ”— Internet ๐Ÿ”— Computing ๐Ÿ”— Blogging ๐Ÿ”— Podcasting

RSS (RDF Site Summary or Really Simple Syndication) is a web feed that allows users and applications to access updates to websites in a standardized, computer-readable format. Subscribing to RSS feeds can allow a user to keep track of many different websites in a single news aggregator, which constantly monitor sites for new content, removing the need for the user to manually check them. News aggregators (or "RSS readers") can be built into a browser, installed on a desktop computer, or installed on a mobile device.

Websites usually use RSS feeds to publish frequently updated information, such as blog entries, news headlines, episodes of audio and video series, or for distributing podcasts. An RSS document (called "feed", "web feed", or "channel") includes full or summarized text, and metadata, like publishing date and author's name. RSS formats are specified using a generic XML file.

Although RSS formats have evolved from as early as March 1999, it was between 2005 and 2006 when RSS gained widespread use, and the ("") icon was decided upon by several major web browsers. RSS feed data is presented to users using software called a news aggregator and the passing of content is called web syndication. Users subscribe to feeds either by entering a feed's URI into the reader or by clicking on the browser's feed icon. The RSS reader checks the user's feeds regularly for new information and can automatically download it, if that function is enabled.
