The expert wizard amendment was a proposed amendment by New Mexico state senator Duncan Scott, which would require psychologists and psychiatrists to dress up as wizards when they were in court proceedings providing expert testimony regarding a defendant's competency. The amendment, proposed in 1995, passed New Mexico's Senate unanimously. Scott revealed the amendment was satirical prior to a vote in New Mexico House of Representatives following which it was removed and thus never signed into law.

Scott said that he crafted the amendment because he felt that there were an excessive number of mental health practitioners acting as expert witnesses.

In professional wrestling, kayfabe (also called work or worked) is the portrayal of staged events within the industry as "real" or "true", specifically the portrayal of competition, rivalries, and relationships between participants as being genuine and not of a staged or predetermined nature of any kind. The term kayfabe has evolved to also become a code word of sorts for maintaining this "reality" within the direct or indirect presence of the general public.

Kayfabe is often seen as the suspension of disbelief that is used to create the non-wrestling aspects of promotions, such as feuds, angles, and gimmicks in a manner similar to other forms of fictional entertainment. In relative terms, a wrestler breaking kayfabe during a show would be likened to an actor breaking character on-camera. Also, since wrestling is performed in front of a live audience, whose interaction with the show is crucial to its success, kayfabe can be compared to the fourth wall in acting, since hardly any conventional fourth wall exists to begin with. In general, everything in a professional wrestling show is to some extent scripted, or "kayfabe", even though at times it is portrayed as real-life.

Kayfabe was fiercely maintained for decades, but with the advent of the Internet wrestling community, and the sports entertainment movement, the pro wrestling industry has become less concerned with protecting so-called backstage secrets and typically maintains kayfabe only during the shows. Kayfabe is, however, occasionally broken during shows, usually when dealing with genuine injuries during a match or paying tribute to wrestlers.

The 1983 U.S. Senate bombing was a bomb explosion at the United States Senate on November 7, 1983, motivated by United States military involvement in Lebanon and Grenada. The attack led to heightened security in the DC metropolitan area, and the inaccessibility of certain parts of the Senate Building. Six members of the radical left-wing Resistance Conspiracy were arrested in May 1988 and charged with the bombing, as well as related bombings of Fort McNair and the Washington Navy Yard which occurred April 25, 1983, and April 20, 1984, respectively.

Banana equivalent dose (BED) is an informal measurement of ionizing radiation exposure, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by eating one average-sized banana. Bananas contain naturally occurring radioactive isotopes, particularly potassium-40 (⁴⁰K), one of several naturally-occurring isotopes of potassium. One BED is often correlated to 10⁻⁷ sievert (0.1 μSv); however, in practice, this dose is not cumulative, as the principal radioactive component is excreted to maintain metabolic equilibrium. The BED is only meant to inform the public about the existence of very low levels of natural radioactivity within a natural food and is not a formally adopted dose measurement.

The winter solstice, hiemal solstice or hibernal solstice, also known as midwinter, occurs when one of the Earth's poles has its maximum tilt away from the Sun. It happens twice yearly, once in each hemisphere (Northern and Southern). For that hemisphere, the winter solstice is the day with the shortest period of daylight and longest night of the year, when the Sun is at its lowest daily maximum elevation in the sky. At the pole, there is continuous darkness or twilight around the winter solstice. Its opposite is the summer solstice.

The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (usually 21 or 22 December) and in the Southern Hemisphere, this is the June solstice (usually 20 or 21 June). Although the winter solstice itself lasts only a moment, the term sometimes refers to the day on which it occurs. Other names are "midwinter", the "extreme of winter" (Dongzhi), or the "shortest day". Traditionally, in many temperate regions, the winter solstice is seen as the middle of winter, but today in some countries and calendars, it is seen as the beginning of winter. In meteorology, winter is reckoned as beginning about three weeks before the winter solstice.

Since prehistory, the winter solstice has been seen as a significant time of year in many cultures, and has been marked by festivals and rituals. It marked the symbolic death and rebirth of the Sun. The seasonal significance of the winter solstice is in the reversal of the gradual lengthening of nights and shortening of days.

The gömböc (Hungarian: [ˈɡømbøt͡s]) is a convex three-dimensional homogeneous body that when resting on a flat surface has just one stable and one unstable point of equilibrium. Its existence was conjectured by the Russian mathematician Vladimir Arnold in 1995 and proven in 2006 by the Hungarian scientists Gábor Domokos and Péter Várkonyi. The gömböc shape is not unique; it has countless varieties, most of which are very close to a sphere and all with a very strict shape tolerance (about 0.1 mm per 100 mm).

The most famous solution, capitalized as Gömböc to distinguish it from the generic gömböc, has a sharpened top, as shown in the photo. Its shape helped to explain the body structure of some tortoises in relation to their ability to return to equilibrium position after being placed upside down. Copies of the gömböc have been donated to institutions and museums, and the largest one was presented at the World Expo 2010 in Shanghai in China. In December 2017, a 4.5 m gömböc statue was installed in the Corvin Quarter in Budapest.

The Limits to Growth (often abbreviated LTG) is a 1972 report that discussed the possibility of exponential economic and population growth with finite supply of resources, studied by computer simulation. The study used the World3 computer model to simulate the consequence of interactions between the Earth and human systems. The model was based on the work of Jay Forrester of MIT,^: 21 as described in his book World Dynamics.

Commissioned by the Club of Rome, the study saw its findings first presented at international gatherings in Moscow and Rio de Janeiro in the summer of 1971.^: 186 The report's authors are Donella H. Meadows, Dennis L. Meadows, Jørgen Randers, and William W. Behrens III, representing a team of 17 researchers.^: 8

The report's findings suggest that, in the absence of significant alterations in resource utilization, it is highly likely that there will be an abrupt and unmanageable decrease in both population and industrial capacity. Despite the report's facing severe criticism and scrutiny upon its release, subsequent research consistently finds that the global use of natural resources has been inadequately reformed since to alter its basic predictions.

Since its publication, some 30 million copies of the book in 30 languages have been purchased. It continues to generate debate and has been the subject of several subsequent publications.

Beyond the Limits and The Limits to Growth: The 30-Year Update were published in 1992 and 2004 respectively; in 2012, a 40-year forecast from Jørgen Randers, one of the book's original authors, was published as 2052: A Global Forecast for the Next Forty Years; and in 2022 two of the original Limits to Growth authors, Dennis Meadows and Jørgen Randers, joined 19 other contributors to produce Limits and Beyond.

The men's marathon at the 1904 Summer Olympics in St. Louis, United States, took place on August 30 of that year, over a distance of 24.85 miles (40 km).

The race was run during the hottest part of the day on dusty country roads with minimal water supply; while thirty-two athletes representing four nations competed, only 14 managed to complete the race, which was a bizarre affair due to poor organization and officiating. While Fred Lorz was greeted as the apparent winner, he was later disqualified as he had hitched a ride in a car for part of the race. The actual winner, Thomas Hicks, was near collapse and hallucinating by the end of the race, a side effect of being administered brandy, raw eggs, and strychnine by his trainers. The fourth-place finisher, Andarín Carvajal, took a nap during the race after eating spoiled apples.

Speed tape is an aluminium pressure-sensitive tape used to perform minor repairs on aircraft and racing cars. It is used as a temporary repair material until a more permanent repair can be carried out. It has an appearance similar to duct tape, for which it is sometimes mistaken, but its adhesive is capable of sticking on an airplane fuselage or wing at high speeds, hence the name.

🔗 Aviation 🔗 Aviation/aircraft

A ram air turbine (RAT) is a small wind turbine that is connected to a hydraulic pump, or electrical generator, installed in an aircraft and used as a power source. The RAT generates power from the airstream by ram pressure due to the speed of the aircraft.
