πŸ”— Variolation

πŸ”— Medicine πŸ”— Viruses

Variolation or inoculation was the method first used to immunize an individual against smallpox (Variola) with material taken from a patient or a recently variolated individual, in the hope that a mild, but protective, infection would result. The procedure was most commonly carried out by inserting/rubbing powdered smallpox scabs or fluid from pustules into superficial scratches made in the skin. The patient would develop pustules identical to those caused by naturally occurring smallpox, usually producing a less severe disease than naturally acquired smallpox. Eventually, after about two to four weeks, these symptoms would subside, indicating successful recovery and immunity. The method was first used in China and the Middle East before it was introduced into England and North America in the 1720s in the face of some opposition. The method is no longer used today. It was replaced by smallpox vaccine, a safer alternative. This in turn led to the development of the many vaccines now available against other diseases.

πŸ”— Community Memory Terminal

πŸ”— Internet culture

Community Memory (CM) was the first public computerized bulletin board system. Established in 1973 in Berkeley, California, it used an SDS 940 timesharing system in San Francisco connected via a 110 baud link to a teleprinter at a record store in Berkeley to let users enter and retrieve messages. Individuals could place messages in the computer and then look through the memory for a specific notice.

While initially conceived as an information and resource sharing network linking a variety of counter-cultural economic, educational, and social organizations with each other and the public, Community Memory was soon generalized to be an information flea market, by providing unmediated, two-way access to message databases through public computer terminals. Once the system became available, the users demonstrated that it was a general communications medium that could be used for art, literature, journalism, commerce, and social chatter.

πŸ”— Asemic Writing

πŸ”— Writing systems πŸ”— Writing

Asemic writing is a wordless open semantic form of writing. The word asemic means "having no specific semantic content", or "without the smallest unit of meaning". With the non-specificity of asemic writing there comes a vacuum of meaning, which is left for the reader to fill in and interpret. All of this is similar to the way one would deduce meaning from an abstract work of art. Where asemic writing distinguishes itself among traditions of abstract art is in the asemic author's use of gestural constraint, and the retention of physical characteristics of writing such as lines and symbols. Asemic writing is a hybrid art form that fuses text and image into a unity, and then sets it free to arbitrary subjective interpretations. It may be compared to free writing or writing for its own sake, instead of writing to produce verbal context. The open nature of asemic works allows for meaning to occur across linguistic understanding; an asemic text may be "read" in a similar fashion regardless of the reader's natural language. Multiple meanings for the same symbolism are another possibility for an asemic work, that is, asemic writing can be polysemantic or have zero meaning, infinite meanings, or its meaning can evolve over time. Asemic works leave for the reader to decide how to translate and explore an asemic text; in this sense, the reader becomes co-creator of the asemic work.

In 1997, visual poets Tim Gaze and Jim Leftwich first applied the word asemic to name their quasi-calligraphic writing gestures. They then began to distribute them to poetry magazines both online and in print. The authors explored sub-verbal and sub-letteral forms of writing, and textual asemia as a creative option and as an intentional practice. Since the late 1990s, asemic writing has blossomed into a worldwide literary/art movement. It has especially grown in the early part of the 21st century, though there is an acknowledgement of a long and complex history, which precedes the activities of the current asemic movement, especially with regards to abstract calligraphy, wordless writing, and verbal writing damaged beyond the point of legibility. Jim Leftwich has recently stated that an asemic condition of an asemic work is an impossible goal, and that it is not possible to create an art/literary work entirely without meaning. He has begun to use the term "pansemic" too. He also explained (in 2020): "The term 'pansemia' didn't replace the term 'asemia' in my thinking (nor did 'pansemic' replace 'asemic'); it merely assisted me in expanding my understanding of the theory and practice of asemic writing". Others such as author Travis Jeppesen have found the term asemic to be problematic because "it seems to infer writing with no meaning."

πŸ”— 1561 Celestial Phenomenon over Nuremberg

πŸ”— Germany πŸ”— Skepticism πŸ”— Paranormal

An April 1561 broadsheet by Hans Glaser described a mass sighting of celestial phenomena or unidentified flying objects (UFO) above Nuremberg (then a Free Imperial City of the Holy Roman Empire). Ufologists have speculated that these phenomena may have been extraterrestrial spacecraft. Skeptics assert that the phenomenon was likely to have been another atmospheric phenomenon, such as a sun dog, although the print doesn't fit the usual classic description of the phenomena.

πŸ”— Aztec Diamond

πŸ”— Science

In combinatorial mathematics, an Aztec diamond of order n consists of all squares of a square lattice whose centers (x,y) satisfy |x| + |y| ≀ n. Here n is a fixed integer, and the square lattice consists of unit squares with the origin as a vertex of 4 of them, so that both x and y are half-integers.

The Aztec diamond theorem states that the number of domino tilings of the Aztec diamond of order n is 2n(n+1)/2. The Arctic Circle theorem says that a random tiling of a large Aztec diamond tends to be frozen outside a certain circle.

It is common to color the tiles in the following fashion. First consider a checkerboard coloring of the diamond. Each tile will cover exactly one black square. Vertical tiles where the top square covers a black square, is colored in one color, and the other vertical tiles in a second. Similarly for horizontal tiles.

Knuth has also defined Aztec diamonds of order n + 1/2. They are identical with the polyominoes associated with the centered square numbers.

πŸ”— 1957 German Grand Prix

πŸ”— Germany πŸ”— Formula One

The 1957 German Grand Prix was a Formula One motor race held on 4 August 1957 at NΓΌrburgring. It was race 6 of 8 in the 1957 World Championship of Drivers. The 22 lap race was won by Juan Manuel Fangio, and is often cited as one of the greatest victories in racing history. It was Fangio's fourth victory out of the seven races in the season contested by Formula 1 cars - excluding the Indianapolis 500, in which only US drivers competed, using USAC Championship cars. Furthermore, due to the number of points he had accumulated in the season (34 to Luigi Musso's 16), his victory at the NΓΌrburgring mathematically clinched Fangio's fifth World Championship title with two races to go. The race was also notable for being Fangio's 24th and last victory in F1; his career still stands as having the highest win percentage ever, with 46.15% of his 52 race entries being wins.

πŸ”— Cheeger constant as a measure of β€œbottleneckedness”

πŸ”— Computing πŸ”— Mathematics πŸ”— Computing/Networking

In mathematics, the Cheeger constant (also Cheeger number or isoperimetric number) of a graph is a numerical measure of whether or not a graph has a "bottleneck". The Cheeger constant as a measure of "bottleneckedness" is of great interest in many areas: for example, constructing well-connected networks of computers, card shuffling. The graph theoretical notion originated after the Cheeger isoperimetric constant of a compact Riemannian manifold.

The Cheeger constant is named after the mathematician Jeff Cheeger.

πŸ”— Basic income

πŸ”— Finance & Investment πŸ”— Economics πŸ”— Sociology πŸ”— Sociology/social movements πŸ”— Basic Income πŸ”— Social Work πŸ”— International development

Basic income, also called universal basic income (UBI), citizen's income, citizen's basic income in the United Kingdom, basic income guarantee in the United States and Canada, or basic living stipend or guaranteed annual income or universal demogrant, is a governmental public program for a periodic payment delivered to all on an individual basis without means test or work requirement. The incomes would be:

  • Unconditional: A basic income would vary with age, but with no other conditions. Everyone of the same age would receive the same basic income, whatever their gender, employment status, family structure, contribution to society, housing costs, or anything else.
  • Automatic: Someone's basic income would be automatically paid weekly or monthly into a bank account or similar.
  • Non-withdrawable: Basic incomes would not be means-tested. Whether someone's earnings increase, decrease, or stay the same, their basic income will not change.
  • Individual: Basic incomes would be paid on an individual basis and not on the basis of a couple or household.
  • As a right: Every legal resident would receive a basic income, subject to a minimum period of legal residency and continuing residency for most of the year.

Basic income can be implemented nationally, regionally or locally. An unconditional income that is sufficient to meet a person's basic needs (at or above the poverty line) is sometimes called a full basic income while if it is less than that amount, it is sometimes called partial. A welfare system with some characteristics similar to those of a basic income is a negative income tax in which the government stipend is gradually reduced with higher labour income. Some welfare systems are sometimes regarded as steps on the way to a basic income, but because they have conditionalities attached they are not basic incomes. If they raise household incomes to specified minima they are called guaranteed minimum income systems. For example, Bolsa FamΓ­lia in Brazil is restricted to poor families and the children are obligated to attend school.

Several political discussions are related to the basic income debate. Examples include the debates regarding robotization, artificial intelligence (AI), and the future of work. A key issue in these debates is whether robotisation and AI will significantly reduce the number of available jobs. Basic income often comes up as a proposal in these discussions.

πŸ”— Euthanasia Coaster

πŸ”— Death πŸ”— Lithuania πŸ”— Amusement Parks πŸ”— Amusement Parks/Roller Coasters

The Euthanasia Coaster is a hypothetical steel roller coaster designed to kill its passengers. In 2010, it was designed and made into a scale model by Lithuanian artist Julijonas Urbonas, a PhD candidate at the Royal College of Art in London. Urbonas, who has worked at an amusement park, stated that the goal of his concept roller coaster is to take lives "with elegance and euphoria". As for practical applications of his design, Urbonas mentioned "euthanasia" or "execution". John Allen, who served as president of the Philadelphia Toboggan Company, inspired Urbonas with his description of the "ultimate" roller coaster as one that "sends out 24 people and they all come back dead".
