In finance and economics, the greater fool theory states that the price of an object is determined not by its intrinsic value, but rather by the local and relative demand of a specific consumer.
In an inflated market, a consumer, despite having broader market knowledge might pay an inflated price because of their needs and the local related-market value. Another consumer, relative to their needs and assessment of market value, may deem the price excessive. Thus, to one consumer, the commodity has a greater value than to another, making the former look like a fool to the latter. Continue reading →

Venatio [ven-ah-tee-oh] (‘hunting’) was a type of entertainment in Roman amphitheaters involving the hunting and killing of wild animals.
The event was introduced by Roman General Marcus Fulvius Nobilior, who celebrated his Greek campaign in 189 BCE by celebrating games where gladiators would fight lions and panthers. He was possibly inspired by Alexander the Great’s purported pastime of pitting lions against both men and dogs. Continue reading →

A diving horse is an attraction that was popular in the mid-1880s, in which a horse would dive into a pool of water, sometimes from as high as 60 feet.
In Lake George, New York, the Magic Forest theme park hosts the only remaining diving horse feature in New York state. It has been in operation since 1977, originally featuring a horse named Rex, later replaced by a gelding named Lightning. The manager states, ‘There is no rider, no prods, no electrical jolts, and no trap doors.’ The horse jumps twice daily during a two-month season and has the rest of the year off. Continue reading →

A boardwalk is an elevated footpath, walkway, or causeway built with wooden planks that enables pedestrians to cross wet, fragile, or marshy land. They are also in effect a low type of bridge. Such timber trackways have existed since at least Neolithic times (12,000 years ago).
An early example is the ‘Sweet Track’ that Neolithic people built in the Somerset levels, England, around 6,000 years ago. This track consisted mainly of planks of oak laid end-to-end, supported by crossed pegs of ash, oak, and lime, driven into the underlying peat (partially decayed vegetation). Continue reading →

Coquina [koh-kee-nuh] is a sedimentary rock that is composed either wholly or almost entirely of the transported, abraded, and mechanically-sorted fragments of the shells of mollusks, trilobites, brachiopods, or other invertebrates. The term coquina comes from the Spanish word for ‘cockle’ and ‘shellfish.’
Coquinas accumulate in high-energy marine and lacustrine environments where currents and waves result in the vigorous winnowing, abrasion, fracturing, and sorting of the shells that compose them. As a result, they typically exhibit well-developed bedding or cross-bedding, close packing, and good orientation of the shell fragments. The high-energy marine or lacustrine (lake) environments associated with coquinas include beaches, shallow submarine raised banks, swift tidal channels, and barrier bars. Continue reading →

George Barris (1925 – 2015) was an American designer and builder of many famous Hollywood custom cars, most notably the Munster Koach and 1966 Batmobile.
George and his brother Sam were born in Chicago in the 1920s. Barris was three years old when their father, a Greek immigrant from Chios, sent the brothers to live with an uncle and his wife in Roseville, California, following the death of their mother. By age 7, Barris was making models of cars employing balsa wood and modifying their design and appearance with careful attention to details so his entries won contests sponsored by hobby shops.

Payot [pey-oht] is the Hebrew word for sidelocks or sideburns. Payot are worn by some men and boys in the Orthodox Jewish community based on an interpretation of the Biblical injunction against shaving the ‘corners’ of one’s head. Literally, ‘pe’ah’ means ‘corner, side, edge.’
There are different styles of payot among Hasidic, Yemenite, and Chardal (Zionist Israeli) Jews. Yemenite Jews call their sidelocks ‘simonim,’ literally, ‘signs,’ because their long-curled sidelocks served as a distinguishing feature in the Yemenite society (differentiating them from their non-Jewish neighbors).

A zombie satellite is a satellite that is no longer under human control due to an extended malfunction. At the end of their service life, the majority of satellites suffer from orbital decay and are destroyed by the heat of atmospheric entry. Zombie satellites, however, maintain a stable orbit but are either partially or completely inoperable, preventing operators from communicating with them.
One of the oldest known zombie satellites is Transit 5B-5, which was launched in 1965 as part of the Transit system. Also known as NAVSAT or NNSS (for Navy Navigation Satellite System), it is one of the first satellite navigation systems (or satnav). Transit 5B-5 is nuclear powered and still in a stable polar orbit, though operators are unable to control it. Continue reading →

Dueling scars have been seen as a ‘badge of honor’ since as early as 1825. Known variously as ‘Mensur scars,’ ‘the bragging scar,’ ‘smite,’ or ‘Schmitte,’ dueling scars were popular among upper-class Austrians and Germans involved in academic fencing at the start of the 20th century.
Among university students, it was seen as a mark of their class and honor. It is an early example of scarification (body modification) in European society. The practice of dueling and the associated scars was also present to some extent in the German military. Continue reading →

Tensegrity [ten-seg-ri-tee], tensional integrity or floating compression is a structural principle based on a system of isolated components under compression inside a network of continuous tension, and arranged in such a way that the compressed members (usually bars or struts) do not touch each other while the prestressed tensioned members (usually cables or tendons) delineate the system spatially.
The term was coined by inventor Buckminster Fuller in the 1960s as a portmanteau of ‘tensional integrity.’ The other denomination of tensegrity, floating compression, was used mainly by the constructivist artist Kenneth Snelson. Shorter columns or struts in compression are stronger than longer ones. This in turn led Fuller to make claims that tensegrity structures could be scaled up to cover whole cities. Continue reading →

Pumpernickel [puhm-per-nik-uhl] is a typically heavy, slightly sweet rye bread traditionally made with sourdough starter and coarsely ground rye. It is often made today with a combination of rye flour and whole rye grains.
Some mass produced pumpernickel in North America may incorporate natural colorants such as molasses, caramel color, coffee, or cocoa powder among others to imitate the various shades of brown of traditional German pumpernickel, which is derived from long baking times and the maillard reaction (a chemical reaction between amino acids and reducing sugars).

‘Lies, damned lies, and statistics‘ is a phrase describing the persuasive power of numbers, particularly the use of statistics to bolster weak arguments. It is also used colloquially to doubt statistics cited to prove an opponent’s point.
The phrase derives from the full sentence, ‘There are three kinds of lies: lies, damned lies, and statistics.’ It was popularized by Mark Twain and others, who mistakenly attributed it to the British prime minister Benjamin Disraeli. The true originator is uncertain, but it has, at times, been attributed to an anonymous writer in mid-1891 and later that year to English politician Sir Charles Dilke. Continue reading →
