π Eagle Cash
Eagle Cash (stylized as EagleCash), and sister program EZpay, are cash management applications that use stored-value card technology to process financial transactions in "closed-loop" operating environments. The United States Department of the Treasury sponsors the programs for the U.S. Armed Forces. The Federal Reserve Bank of Boston administers the programs for the Treasury, and they are in use at approved U.S. military facilities inside and outside the continental United States. The systems use a plastic payment card, similar to a credit or debit card, which has an embedded microchip that tracks the card's balance and interfaces with encrypted card readers. This method allows soldiers to purchase goods and services at U.S. military posts and canteens, without carrying cash, or manage their personal bank accounts while on deployment or in training. The program reduces the amount of American currency required overseas, reduces theft, saves thousands of man-hours in labor, helps reduce the risk of transporting cash in combat environments, and increases security and convenience for service members. It helped reduce or eliminate the need for cash and money orders.

π Amplituhedron
An amplituhedron is a geometric structure introduced in 2013 by Nima Arkani-Hamed and Jaroslav Trnka. It enables simplified calculation of particle interactions in some quantum field theories. In planar N = 4 supersymmetric YangβMills theory, also equivalent to the perturbative topological B model string theory in twistor space, an amplituhedron is defined as a mathematical space known as the positive Grassmannian.
Amplituhedron theory challenges the notion that spacetime locality and unitarity are necessary components of a model of particle interactions. Instead, they are treated as properties that emerge from an underlying phenomenon.
The connection between the amplituhedron and scattering amplitudes is at present a conjecture that has passed many non-trivial checks, including an understanding of how locality and unitarity arise as consequences of positivity. Research has been led by Nima Arkani-Hamed. Edward Witten described the work as "very unexpected" and said that "it is difficult to guess what will happen or what the lessons will turn out to be".

π Paradox of Plenty
The resource curse, also known as the paradox of plenty or the poverty paradox, is the phenomenon of countries with an abundance of natural resources (such as fossil fuels and certain minerals) having less economic growth, less democracy, or worse development outcomes than countries with fewer natural resources. There are many theories and much academic debate about the reasons for and exceptions to the adverse outcomes. Most experts believe the resource curse is not universal or inevitable but affects certain types of countries or regions under certain conditions.

π Idiocracy
Idiocracy is a 2006 American science fiction comedy film co-produced and directed by Mike Judge from a screenplay written by Judge and Etan Cohen based on a story written by Judge. The plot follows United States Army librarian Joe Bauers and prostitute Rita, who undergo a government hibernation experiment. Joe and Rita awake five hundred years later in a dystopian anti-intellectual society. The cast includes Luke Wilson, Maya Rudolph, Dax Shepard, Terry Crews, David Herman, Justin Long, Andrew Wilson, and Brad Jordan.
The concept of Idiocracy dates back to a concept Judge envisioned in 1996. Judge finished a script with the working title 3001 in 2001, rewriting the film a year later. Filming took place throughout 2004 at Austin Studios and other cities in Texas. Idiocracy serves as a social satire that touches on issues including anti-intellectualism, commercialism, consumerism, dysgenics, voluntary childlessness, and overpopulation. 20th Century Fox was hesitant to promote the film, refusing to grant it a wide release, and did not screen the film for critics. The decision not to market Idiocracy was seen as unexpected, following the success of Office Space (1999), and led to speculation. According to Crews, the film's satirical depiction of corporations made the film financially unviable, while Judge attributed 20th Century Fox's decision to negative test screenings; Judge stated that 20th Century Fox believed that the film would develop a cult following through its DVD release, similar to Office Space.
The film was released in the United States on September 1, 2006. Despite its lack of a major theatrical release, which resulted in a $495,000 gross at the box office, the film received positive reviews from critics and has since become a cult film.

π Unethical human experimentation in the United States
Unethical human experimentation in the United States describes numerous experiments performed on human test subjects in the United States that have been considered unethical, and were often performed illegally, without the knowledge, consent, or informed consent of the test subjects. Such tests have occurred throughout American history, but particularly in the 20th century. The experiments include: the exposure of humans to many chemical and biological weapons (including infection with deadly or debilitating diseases), human radiation experiments, injection of toxic and radioactive chemicals, surgical experiments, interrogation and torture experiments, tests involving mind-altering substances, and a wide variety of others. Many of these tests were performed on children, the sick, and mentally disabled individuals, often under the guise of "medical treatment". In many of the studies, a large portion of the subjects were poor, racial minorities, or prisoners.
Funding for many of the experiments was provided by the United States government, especially the United States military, the Central Intelligence Agency, or private corporations involved with military activities. The human research programs were usually highly secretive, and in many cases information about them was not released until many years after the studies had been performed.
The ethical, professional, and legal implications of this in the United States medical and scientific community were quite significant, and led to many institutions and policies that attempted to ensure that future human subject research in the United States would be ethical and legal. Public outrage in the late 20th century over the discovery of government experiments on human subjects led to numerous congressional investigations and hearings, including the Church Committee and Rockefeller Commission, both of 1975, and the 1994 Advisory Committee on Human Radiation Experiments, among others.

π Bakelite β first commercial synthetic plastic
Bakelite ( BAY-kΙ-lyte) was the first plastic made from synthetic components. It was developed by chemist Leo Baekeland in Yonkers, New York, in 1907, and patented on December 7, 1909.
Bakelite was a commercial success because it could be molded into any shape. It was used for such diverse products as kitchenware, jewelry, pipe stems, children's toys, and firearms. Because Bakelite is heat-resistant and electrically nonconductive, it was also used to make products such as electrical insulators and casings for radios and telephones.
The creation of a synthetic plastic was revolutionary for the chemical industry, which at the time was mostly focused on cloth dyes and explosives. Bakelite's commercial success led to other synthetic plastics. As the world's first commercial synthetic plastic, Bakelite was named a National Historic Chemical Landmark by the American Chemical Society.
Formally, Bakelite is polyΒoxyΒbenzylΒmethyleneΒglycolΒanhydride, a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde.
The retro appeal of old Bakelite products has made them collectible.

π Jacquard Machine
The Jacquard machine (French:Β [ΚakaΚ]) is a device fitted to a power loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassΓ©. It was invented by Joseph Marie Jacquard in 1804, based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740). The machine was controlled by a "chain of cards"; a number of punched cards laced together into a continuous sequence. Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design. Several such paper cards, generally white in color, can be seen in the images below. Chains, like Bouchon's earlier use of paper tape, allowed sequences of any length to be constructed, not limited by the size of a card.
Both the Jacquard process and the necessary loom attachment are named after their inventor. This mechanism is probably one of the most important weaving inventions as Jacquard shedding made possible the automatic production of unlimited varieties of pattern weaving. The term "Jacquard" is not specific or limited to any particular loom, but rather refers to the added control mechanism that automates the patterning. The process can also be used for patterned knitwear and machine-knitted textiles, such as jerseys.
This use of replaceable punched cards to control a sequence of operations is considered an important step in the history of computing hardware.

π Airbus Beluga
The Airbus A300-600ST (Super Transporter), or Beluga, is a version of the standard A300-600 wide-body airliner modified to carry aircraft parts and outsize cargo. It received the official name of Super Transporter early on; however, the name Beluga, a whale it resembles, gained popularity and has since been officially adopted. The Beluga XL, based on the Airbus A330 with similar modifications and dimensions, was developed by Airbus to replace the type in January 2020.

π Democracy Distribution of the World
The Democracy Index is an index compiled by the Economist Intelligence Unit (EIU), a UK-based company. It intends to measure the state of democracy in 167 countries, of which 166 are sovereign states and 164 are UN member states.
The index was first published in 2006, with updates for 2008, 2010 and later years. The index is based on 60 indicators grouped in five different categories, measuring pluralism, civil liberties and political culture. In addition to a numeric score and a ranking, the index categorises each country in one of four regime types: full democracies, flawed democracies, hybrid regimes and authoritarian regimes.
