A chicken can be hypnotized, or put into a trance, by holding its head down against the ground, and drawing a line along the ground with a stick or a finger, starting at the beak and extending straight outward in front of the chicken. If the chicken is hypnotized in this manner, it will continue to stare at the line, remaining immobile for as long as 30 minutes. Other methods of inducing this state are also known. Ethologists refer to this state as 'tonic immobility' i.e. a natural state of semi-paralysis that some animals enter when presented with a threat, which is probably a defensive mechanism intended to feign death, albeit rather poorly.

The first known written reference for this method came in 1646, in Mirabele Experimentum de Imaginatione Gallinae by Athanasius Kircher in Rome.

Hachikō (ハチ公, November 10, 1923 – March 8, 1935) was a Japanese Akita dog remembered for his remarkable loyalty to his owner, Hidesaburō Ueno, for whom he continued to wait for over nine years following Ueno's death.

Hachikō was born on November 10, 1923, at a farm near the city of Ōdate, Akita Prefecture. In 1924, Hidesaburō Ueno, a professor at the Tokyo Imperial University, brought him to live in Shibuya, Tokyo, as his pet. Hachikō would meet Ueno at Shibuya Station every day after his commute home. This continued until May 21, 1925, when Ueno died of a cerebral hemorrhage while at work. From then until his death on March 8, 1935, Hachikō would return to Shibuya Station every day to await Ueno's return.

During his lifetime, the dog was held up in Japanese culture as an example of loyalty and fidelity. Well after his death, he continues to be remembered in worldwide popular culture, with statues, movies, books, and appearances in various media. Hachikō is known in Japanese as chūken Hachikō (忠犬ハチ公) "faithful dog Hachikō", hachi meaning "eight" and the suffix -kō indicating affection.

This list of eponymous laws provides links to articles on laws, principles, adages, and other succinct observations or predictions named after a person. In some cases the person named has coined the law – such as Parkinson's law. In others, the work or publications of the individual have led to the law being so named – as is the case with Moore's law. There are also laws ascribed to individuals by others, such as Murphy's law; or given eponymous names despite the absence of the named person.

In computer programming jargon, a heisenbug is a software bug that seems to disappear or alter its behavior when one attempts to study it. The term is a pun on the name of Werner Heisenberg, the physicist who first asserted the observer effect of quantum mechanics, which states that the act of observing a system inevitably alters its state. In electronics the traditional term is probe effect, where attaching a test probe to a device changes its behavior.

Similar terms, such as bohrbug, mandelbug, hindenbug, and schrödinbug (see the section on related terms) have been occasionally proposed for other kinds of unusual software bugs, sometimes in jest; however, unlike the term heisenbug, they are not widely known or used.

It's often said that Wikipedia is dying. This is the latest in a long line of technological deaths. Earlier, the WikiWikiWeb died. Before that, Usenet died.

Reasons why Wikipedia is dying include and may not be limited to:

• most of the major editors are leaving
• most edits are now made by robots
• article syntax is too complicated for readers and new editors
• pop culture articles are longer than science or history articles
• power-hungry administrators are warring against content creators so they can delete everything and rule a perfect, empty wiki [Is this right? -- Ed.]
• the people with the most time to edit are also those with the most time and inclination to argue in perpetuity
• the Great Space Wombat said it is dying
• bias is going to destroy the entire neutral point of view we uphold so much
• vandalism. No elaboration required.
• the WMF is more corrupt than governments
• discussion here is more toxic than on Twitter
• nobody is donating (why else do they keep asking for money?)
• people will stop visiting the main site and just get blurbs from search engines or chatbots instead
• insert additional reasons here

Wikipedia has been dying since at least 100 years ago.

Benford's law, also called the Newcomb–Benford law, the law of anomalous numbers, or the first-digit law, is an observation about the frequency distribution of leading digits in many real-life sets of numerical data. The law states that in many naturally occurring collections of numbers, the leading digit is likely to be small. For example, in sets that obey the law, the number 1 appears as the leading significant digit about 30% of the time, while 9 appears as the leading significant digit less than 5% of the time. If the digits were distributed uniformly, they would each occur about 11.1% of the time. Benford's law also makes predictions about the distribution of second digits, third digits, digit combinations, and so on.

The graph to the right shows Benford's law for base 10, one of infinitely many cases of a generalized law regarding numbers expressed in arbitrary (integer) bases, which rules out the possibility that the phenomenon might be an artifact of the base 10 number system. Further generalizations were published by Hill in 1995 including analogous statements for both the nth leading digit as well as the joint distribution of the leading n digits, the latter of which leads to a corollary wherein the significant digits are shown to be a statistically dependent quantity. ).

It has been shown that this result applies to a wide variety of data sets, including electricity bills, street addresses, stock prices, house prices, population numbers, death rates, lengths of rivers, and physical and mathematical constants. Like other general principles about natural data—for example the fact that many data sets are well approximated by a normal distribution—there are illustrative examples and explanations that cover many of the cases where Benford's law applies, though there are many other cases where Benford's law applies that resist a simple explanation. It tends to be most accurate when values are distributed across multiple orders of magnitude, especially if the process generating the numbers is described by a power law (which are common in nature).

The law is named after physicist Frank Benford, who stated it in 1938 in a paper titled "The Law of Anomalous Numbers", although it had been previously stated by Simon Newcomb in 1881.

In mathematical logic, Goodstein's theorem is a statement about the natural numbers, proved by Reuben Goodstein in 1944, which states that every Goodstein sequence eventually terminates at 0. Laurence Kirby and Jeff Paris showed that it is unprovable in Peano arithmetic (but it can be proven in stronger systems, such as second-order arithmetic). This was the third example of a true statement about natural numbers that is unprovable in Peano arithmetic, after the examples provided by Gödel's incompleteness theorem and Gerhard Gentzen's 1943 direct proof of the unprovability of ε₀-induction in Peano arithmetic. The Paris–Harrington theorem gave another example.

Kirby and Paris introduced a graph-theoretic hydra game with behavior similar to that of Goodstein sequences: the "Hydra" (named for the mythological multi-headed Hydra of Lerna) is a rooted tree, and a move consists of cutting off one of its "heads" (a branch of the tree), to which the hydra responds by growing a finite number of new heads according to certain rules. Kirby and Paris proved that the Hydra will eventually be killed, regardless of the strategy that Hercules uses to chop off its heads, though this may take a very long time. Just like for Goodstein sequences, Kirby and Paris showed that it cannot be proven in Peano arithmetic alone.

Tymnet was an international data communications network headquartered in Cupertino, California that used virtual call packet-switched technology and X.25, SNA/SDLC, BSC and Async interfaces to connect host computers (servers) at thousands of large companies, educational institutions, and government agencies. Users typically connected via dial-up connections or dedicated asynchronous connections.

The business consisted of a large public network that supported dial-up users and a private network that allowed government agencies and large companies (mostly banks and airlines) to build their own dedicated networks. The private networks were often connected via gateways to the public network to reach locations not on the private network. Tymnet was also connected to dozens of other public networks in the United States and internationally via X.25/X.75 gateways.

As the Internet grew and became almost universally accessible in the late 1990s, the need for services such as Tymnet migrated to the Internet style connections, but still had some value in the Third World and for specific legacy roles. However the value of these links continued to decrease, and Tymnet shut down in 2004.

Fart lighting also known as pyroflatulence, or flatus ignition is the practice of igniting the gases produced by flatulence. The resulting flame is often of a blue hue hence the act being known colloquially as a "blue angel", "blue dart" or in Australia, a "blue flame". The fact that flatus is flammable and the actual combustion of it through this practice gives rise to much humorous derivation. Other colors of flame such as orange and yellow are possible depending on the mixture of gases formed in the colon.

In 1999 author Jim Dawson observed that fart lighting has been a novelty practice primarily among young men or college students for decades but is discouraged for its potential for causing harm. Such experiments typically occur on camping trips and in same-sex group residences, such as tree-houses, dormitories, or fraternity houses. With the advent of video sharing features online, hundreds of self-produced videos, both documentary as well as spoof, have been posted to sites such as YouTube. The people appearing in the videos are predominantly young teen males. In his book The Curse of the Self: Self-Awareness, Egotism, and the Quality of Human Life author Mark Richard Leary explains how a great deal of unhappiness is due to people's inability to exert control over their thoughts and behavior and that "stupid stunts", including lighting flatulence, were a way to make an impression and be included in group bonding or hazing.

Although there is little scientific discourse on the combustive properties of flatus, there are many anecdotal accounts of flatus ignition and the activity has increasingly found its way into popular culture with references in comic routines, movies, and television; including cartoons. In Electric Don Quixote: The Definitive Story of Frank Zappa author Neil Slaven quotes Frank Zappa for calling fart lighting "The manly art of fart-burning", and another book quotes the musician Kenny Williams for saying that it demonstrates "compression, ignition, combustion and exhaust."

There have been documented cases of flatulence during surgery being inadvertently ignited causing patient injury and the risk of death.
