Mike the Headless Chicken (April 20, 1945 – March 17, 1947), also known as Miracle Mike, was a Wyandotte chicken that lived for 18 months after his head had been cut off. Although the story was thought by many to be a hoax, the bird's owner took him to the University of Utah in Salt Lake City to establish the facts.

A shotgun clause (or Texas Shootout Clause) is a term of art, rather than a legal term. It is a specific type of exit provision that may be included in a shareholders' agreement, and may often be referred to as a buy-sell agreement. The shotgun clause allows a shareholder to offer a specific price per share for the other shareholder(s)' shares; the other shareholder(s) must then either accept the offer or buy the offering shareholder's shares at that price per share.

The Boom XB-1 Baby Boom is a one-third-scale supersonic demonstrator designed by Boom Technology, designed as part of development of the Boom Overture supersonic transport airliner. It is planned to maintain Mach 2.2, with over 1,000 nmi (1,900 km) of range. Powered by three 4,300 lbf (19 kN) dry General Electric CJ610s, it is expected to be flight tested in 2020.

🔗 Linguistics 🔗 Linguistics/Applied Linguistics 🔗 Writing systems

The orthographic depth of an alphabetic orthography indicates the degree to which a written language deviates from simple one-to-one letter–phoneme correspondence. It depends on how easy it is to predict the pronunciation of a word based on its spelling: shallow orthographies are easy to pronounce based on the written word, and deep orthographies are difficult to pronounce based on how they are written.

In shallow orthographies, the spelling-sound correspondence is direct: from the rules of pronunciation, one is able to pronounce the word correctly. In other words, shallow (transparent) orthographies, also called phonemic orthographies, have a one-to-one relationship between its graphemes and phonemes, and the spelling of words is very consistent. Such examples include Hindi, Spanish, Finnish, Turkish, Latin and Italian.

In contrast, in deep (opaque) orthographies, the relationship is less direct, and the reader must learn the arbitrary or unusual pronunciations of irregular words. In other words, deep orthographies are writing systems that do not have a one-to-one correspondence between sounds (phonemes) and the letters (graphemes) that represent them. They may reflect etymology (English, Faroese, Mongolian script, Thai, French, or Franco-Provençal) or be morphophonemic (Korean or Russian).

Written Korean represents an unusual hybrid; each phoneme in the language is represented by a letter but the letters are packaged into "square" units of two to four phonemes, each square representing a syllable. Korean has very complex phonological variation rules, especially regarding the consonants rather than the vowels, in contrast to English. For example, the Korean word 훗일, which should be pronounced as [husil] based on standard pronunciations of the components of the grapheme, is actually pronounced as [hunnil]. Among the consonants of the Korean language, only one is always pronounced exactly as it is written.

Italian offers clear examples of differential directionality in depth. Even in a very shallow orthographic system, spelling-to-pronunciation and pronunciation-to-spelling may not be equally clear. There are two major imperfect matches of vowels to letters: in stressed syllables, e can represent either open [ɛ] or closed [e], and o stands for either open [ɔ] or closed [o]. According to the orthographic principles used for the language, [ˈsɛtta] 'sect', for example, with open [ɛ] can only be spelled setta, and [ˈvetta] 'summit' with closed [e] can only be vetta — if a listener can hear it, they can spell it. But since the letter e is assigned to represent both [ɛ] and [e], there is no principled way to know whether to pronounce the written words setta and vetta with [ɛ] or [e] — the spelling does not present the information needed for accurate pronunciation. A second lacuna in Italian's shallow orthography is that although stress position in words is only very partially predictable, it is normally not indicated in writing. For purposes of spelling, it makes no difference which syllable is stressed in the place names Arsoli and Carsoli, but the spellings offer no clue that they are ARsoli and CarSOli (and as with the letter e above, the stressed o of Carsoli, which is [ɔ], is unknown from the spelling).

🔗 Philosophy 🔗 Psychology 🔗 Philosophy/Social and political philosophy 🔗 Sociology

In social psychology, social loafing is the phenomenon of a person exerting less effort to achieve a goal when he or she works in a group than when working alone and is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals. Research on social loafing began with rope pulling experiments by Ringelmann, who found that members of a group tended to exert less effort in pulling a rope than did individuals alone. In more recent research, studies involving modern technology, such as online and distributed groups, have also shown clear evidence of social loafing. Many of the causes of social loafing stem from individual members feeling their individual effort will not matter to the group.

The French professor of agricultural engineering called Max Ringelman demonstrated what “social loafing” was in the 1890s. Ringelman, who was also considered one of the founders of social psychology, made people pull on ropes separately and in groups, and he measured and compared how hard they pulled. After collecting the results he realized that members of a group tended to exert less effort in pulling a rope than did individuals alone. In more recent research, studies involving modern technology, such as online and distributed groups, have also shown clear evidence of social loafing. Many of the causes of social loafing stem from individual members feeling that his or her effort will not matter to the group. This is seen as one of the main reasons groups are sometimes less productive than the combined performance of their members working as individuals, but should be distinguished from the accidental coordination problems that groups sometimes experience.

Several studies found, a lack of an understanding of individual contributions, unchallenging tasks given to the individual, low personal satisfaction from the task, and a lack of a united group to be the most prevalent motivational origins of social loafing. Theories investigating why social loafing occurs range from a group member feeling their contribution will not be noticed to a group member realizing their efforts are not necessary. In a work setting, most managers agree if a task is new or complex employees should work alone. While tasks that are well known and have room for individual effort are better when done in groups.

In order to diminish social loafing from a group, several strategies could be put forward. Social loafing primarily happens when an individual unconscious or conscious exerts less effort due to a decrease in social awareness. In order to counteract the likelihood of this happening, Miguel Herraez, conducted a study on students where he used accountability and cooperation when unequal participation is found. The students were encouraged to do provide equal participation in the work and to point out sources of conflict that could arise. The conclusion of the study found that providing support to the group members lacking in commitment and creating options for independence among group members lowered social loafing. The support for the weaker students improves their standing while also benefiting the other students.

Social loafing should be distinguished from the accidental coordination problems that groups sometimes experience.

"Prawo Jazdy" was a supposed Polish national who was listed by the Garda Síochána in a police criminal database as having committed more than 50 traffic violations in Ireland. A 2007 memorandum stated that an investigation revealed prawo jazdy [ˈpra.vɔ ˈjaz.dɨ] to be Polish for 'driving licence', with the error arising due to officers mistaking the phrase, printed on Polish driving licenses, to be a personal name while issuing traffic tickets.

The Dyatlov Pass incident (Russian: Гибель тургруппы Дятлова) was an event where nine Russian hikers died in the northern Ural Mountains between 1 and 2 February 1959, in uncertain circumstances. The experienced trekking group, who were all from the Ural Polytechnical Institute, had established a camp on the slopes of Kholat Syakhl, in an area now named in honor of the group's leader, Igor Dyatlov. During the night, something caused them to tear their way out of their tents and flee the campsite, all while inadequately dressed for the heavy snowfall and sub-zero temperatures.

After the group's bodies were discovered, an investigation by Soviet authorities determined that six had died from hypothermia while the other three showed signs of physical trauma. One victim had a fractured skull; two others had major chest fractures and the body of one of the group was missing both its eyes. One of the victims was missing a tongue. The investigation concluded that a "compelling natural force" had caused the deaths. Numerous theories have been put forward to account for the unexplained deaths, including animal attacks, hypothermia, avalanche, katabatic winds, infrasound-induced panic, military involvement, or some combination of these.

The Hierapolis sawmill was a Roman water-powered stone sawmill at Hierapolis, Asia Minor (modern-day Turkey). Dating to the second half of the 3rd century AD, the sawmill is considered the earliest known machine to combine a crank with a connecting rod to form a crank slider mechanism.

The watermill is evidenced by a raised relief on the sarcophagus of a certain Marcus Aurelius Ammianos, a local miller. On the pediment a waterwheel fed by a mill race is shown powering via a gear train two frame saws cutting rectangular blocks by the way of connecting rods and, through mechanical necessity, cranks (see diagram). The accompanying inscription is in Greek and attributes the mechanism to Ammianos' "skills with wheels".

🔗 Toys

A pop-pop boat is a toy with a very simple steam engine without moving parts, typically powered by a candle or vegetable oil burner. The name comes from the noise made by some versions of the boats. Other names are putt-putt boat, crazy boat, flash-steamer, hot-air-boat, pulsating water engine boat. Around the world they may be called Can-Can-boot, Knatterboot, toc-toc, Puf-Puf boat, Poof Poof craft, Phut-Phut, or Pouet-Pouet.

🔗 Linguistics

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.
