๐ Distributism
Distributism is an economic theory asserting that the world's productive assets should be widely owned rather than concentrated.
Developed in Europe in the late 19th and early 20th centuries, distributism was based upon the principles of Catholic social teaching, especially the teachings of Pope Leo XIII in his encyclical Rerum novarum (1891) and Pope Pius XI in Quadragesimo anno (1931). It views both capitalism and socialism as equally flawed and exploitative, and it favors economic mechanisms such as cooperatives and member-owned mutual organizations as well as small businesses, and large-scale antitrust regulations.
Some Christian democratic political parties have advocated distributism in their economic policies.

๐ Primer (film)
Primer is a 2004 American science fiction film about the accidental discovery of time travel. The film was written, directed, produced, edited and scored by Shane Carruth, who also stars with David Sullivan.
Primer is of note for its extremely low budget, experimental plot structure, philosophical implications, and complex technical dialogue, which Carruth, a college graduate with a degree in mathematics and a former engineer, chose not to simplify for the sake of the audience. The film collected the Grand Jury Prize at the 2004 Sundance Film Festival, before securing a limited release in the United States, and has since gained a cult following.

๐ 1989 California Medfly Attack
In 1989, a sudden invasion of Mediterranean fruit flies (Ceratitis capitata, "medflies") appeared in California and began devastating crops. Scientists were puzzled and said that the sudden appearance of the insects "defies logic", and some speculated "biological terrorists" were responsible. Analysis suggested that an outside hand played a role in the dense infestation.
A person or group calling itself "The Breeders" took responsibility for the bioterrorist attack, as financial retaliation for the environmental damage caused by the state's Malathion aerial spraying; the group's members were never identified. Subsequently, three months after "The Breeders" announced the medfly release, the state ended its decade-long Malathion program and sought alternate ways to handle destructive insects.

๐ Kei Car
Kei car (or keijidลsha, kanji: ่ปฝ่ชๅ่ป, "light automobile", pronouncedย [keหdสidoหษa]), known variously outside Japan as Japanese city car, ultramini, or Japanese microcar, is the Japanese vehicle category for the smallest highway-legal passenger cars. Similar Japanese categories exist for microvans, and kei trucks. These vehicles are most often the Japanese equivalent of the EU A-segment (city cars).
The kei-car category was created by the Japanese government in 1949, and the regulations have been revised several times since. These regulations specify a maximum vehicle size, engine capacity, and power output, so that owners may enjoy both tax and insurance benefits. In most rural areas they are also exempted from the requirement to certify that adequate parking is available for the vehicle.
Kei cars have become very successful in Japan, consisting of over one-third of domestic new-car sales in fiscal 2016, despite dropping from a record 40% market share in 2013, after the government increased the kei-car tax by 50% in 2014. In 2018, seven of the 10 top-selling models were kei cars, including the top four, all boxy passenger vans: Honda N-Box, Suzuki Spacia, Nissan Dayz, and Daihatsu Tanto. Isuzu is the only manufacturer that has never offered a kei-sized vehicle for either private ownership or commercial trucks and microvans.
In export markets, though, the genre is generally too specialized and too small for most models to be profitable. Notable exceptions exist, though, for instance the Suzuki Alto and Jimny models, which were exported consistently from around 1980. Kei cars are not only popular with the elderly, but they are also popular with youths because of their affordability.
Nearly all kei cars have been designed and manufactured in Japan, but a version of the French-made Smart was briefly imported and officially classified as a kei car, and since then, the British Caterham 7 160 has also received such classification.

๐ Better Portable Graphics
Better Portable Graphics (BPG) is a file format for coding digital images, which was created by programmer Fabrice Bellard in 2014. He has proposed it as a replacement for the JPEG image format as the more compression-efficient alternative in terms of image quality or file size.
It is based on the intra-frame encoding of the High Efficiency Video Coding (HEVC) video compression standard. Tests on photographic images in July 2014 found that BPG produced smaller files for a given quality than JPEG, JPEG XR and WebP.
The format has been designed to be portable and work in low memory environments, and used in portable handheld and IoT devices, where those properties are particularly important. Current research works on designing and developing more energy-efficient BPG hardware which can then be integrated in portable devices such as digital cameras.
While there is no built-in native support for BPG in any mainstream browsers, websites can still deliver BPG images to all browsers by including a JavaScript library written by Bellard.

๐ Underarm Bowling Incident of 1981
The underarm bowling incident of 1981 is a sporting controversy that took place on 1 February 1981, when Australia played New Zealand in a One Day International cricket match, the third in the best-of-five final of the 1980โ81 World Series Cup, at the Melbourne Cricket Ground.
With one ball of the final over remaining in the match, New Zealand required a six to tie the match. To ensure that New Zealand were unable to achieve this, the Australian captain Greg Chappell instructed his bowler (and younger brother) Trevor Chappell to deliver the last ball to batsman Brian McKechnie underarm along the ground. Trevor did so, forcing McKechnie to play the ball defensively, meaning Australia won. This action, although legal at the time, was nevertheless widely perceived as being wholly against the traditional spirit of cricketing fair play.
The outrage caused by the incident eventually led to an official amendment to the international laws of cricket to prevent it from occurring again.

๐ British Post Office Scandal
The British Post Office scandal is a widespread and long-lasting series of individual miscarriages of justice which, between 1999 and 2015, involved over 700 subpostmasters being wrongly convicted of theft, false accounting and fraud when shortfalls at their branches were in fact due to errors of the Post Office's Horizon accounting software. In 2019, the High Court ruled that the Horizon system was faulty and in 2020 the government established a public inquiry. Courts began to quash convictions from 2010. As of January 2024, some victims are still fighting to have their convictions overturned and receive compensation, the public inquiry is ongoing, and the Metropolitan Police is investigating the Post Office for potential fraud offences.
The Horizon accounting system was developed by ICL Pathway, owned by the Japanese company Fujitsu. In 1999, the Post Office started to roll out the new software to its branch and sub-offices, the latter managed by subpostmasters on a self-employed basis under contracts with the Post Office. Almost immediately, some subpostmasters noticed the new system reporting false shortfalls, sometimes for thousands of pounds. The Post Office insisted that the system was robust and, when shortfalls occurred, prosecuted the subpostmasters or forced them to make up the amount. The impact of court cases, criminal convictions, imprisonment, loss of livelihood and homes, debt and bankruptcy took a heavy toll on victims and their families, leading to stress, illness, divorce and, in at least four cases, suicide. In May 2009, Computer Weekly broke the story about problems with Horizon software and in September 2009 subpostmaster Alan Bates set up the Justice for Subpostmasters Alliance (JFSA). In 2012, as a result of pressure from campaigners and Members of Parliament, the Post Office appointed forensic accountants Second Sight to conduct an investigation into Horizon. The investigators concluded that Horizon contained faults that could result in accounting discrepancies, but the Post Office insisted that there were no system-wide problems with the software.
In 2019 a group of 555 subpostmasters led by Bates won a group action brought in court against the Post Office, with the judge ruling that Horizon contained bugs, errors and defects. The Post Office agreed to settle out of court for ยฃ58 million. The subpostmasters' legal costs amounted to ยฃ47 million of, leaving them with only about ยฃ20,000 each. The government later agreed to supplement the settlement, as they were excluded from the compensation scheme set up by the Post Office for other victims of the scandal. The first convictions to be quashed were those of six subpostmasters who had been convicted in magistrates' courts and whose appeals were heard at Southwark Crown Court in December 2020. In allowing the appeal by 39 subpostmasters in April 2021, the Court of Appeal judges ruled that in cases that relied on Horizon data a fair trial was not possible. Further appeal cases followed.
In September 2020, the government established the Post Office Horizon IT Inquiry, chaired by retired judge Sir Wyn Williams, to look into the implementation and failings of the Horizon system that led to the prosecution of subpostmasters and termination of their contracts. Evidence was due to be heard from subpostmasters, the Post Office, UK Government Investment, the Department for Business and Trade, and others.
A four-part television drama, Mr Bates vs the Post Office, was broadcast on ITV in January 2024, after which the scandal became a major news story and political issue.

๐ Gravitation water vortex power plant
The gravitation water vortex power plant is a type of micro hydro vortex turbine system which is capable of converting energy in a moving fluid to rotational energy using a low hydraulic head of 0.7โ3 metres (2ย ft 4ย inโ9ย ft 10ย in). The technology is based on a round basin with a central drain. Above the drain the water forms a stable line vortex which drives a water turbine.
It was first patented by Greek-Australian Lawyer & Inventor Paul Kouris in 1996, who was searching for a way to harness the power inherent in a vortex.
Later, Austrian Inventor Franz Zotlรถterer created a similar turbine while attempting to find a way to aerate water without an external power source.

๐ Entropic Gravity
Entropic gravity, also known as emergent gravity, is a theory in modern physics that describes gravity as an entropic forceโa force with macro-scale homogeneity but which is subject to quantum-level disorderโand not a fundamental interaction. The theory, based on string theory, black hole physics, and quantum information theory, describes gravity as an emergent phenomenon that springs from the quantum entanglement of small bits of spacetime information. As such, entropic gravity is said to abide by the second law of thermodynamics under which the entropy of a physical system tends to increase over time.
At its simplest, the theory holds that when gravity becomes vanishingly weakโlevels seen only at interstellar distancesโit diverges from its classically understood nature and its strength begins to decay linearly with distance from a mass.
Entropic gravity provides the underlying framework to explain Modified Newtonian Dynamics, or MOND, which holds that at a gravitational acceleration threshold of approximately 1.2ร10โ10ย m/s2, gravitational strength begins to vary inversely (linearly) with distance from a mass rather than the normal inverse-square law of the distance. This is an exceedingly low threshold, measuring only 12ย trillionths gravity's strength at earth's surface; an object dropped from a height of one meter would fall for 36 hours were earth's gravity this weak. It is also 3,000 times less than exists at the point where Voyager 1 crossed our solar system's heliopause and entered interstellar space.
The theory claims to be consistent with both the macro-level observations of Newtonian gravity as well as Einstein's theory of general relativity and its gravitational distortion of spacetime. Importantly, the theory also explains (without invoking the existence of dark matter and its accompanying math featuring new free parameters that are tweaked to obtain the desired outcome) why galactic rotation curves differ from the profile expected with visible matter.
The theory of entropic gravity posits that what has been interpreted as unobserved dark matter is the product of quantum effects that can be regarded as a form of positive dark energy that lifts the vacuum energy of space from its ground state value. A central tenet of the theory is that the positive dark energy leads to a thermal-volume law contribution to entropy that overtakes the area law of anti-de Sitter space precisely at the cosmological horizon.
The theory has been controversial within the physics community but has sparked research and experiments to test its validity.

๐ Burning Ship Fractal
The Burning Ship fractal, first described and created by Michael Michelitsch and Otto E. Rรถssler in 1992, is generated by iterating the function:
in the complex plane which will either escape or remain bounded. The difference between this calculation and that for the Mandelbrot set is that the real and imaginary components are set to their respective absolute values before squaring at each iteration. The mapping is non-analytic because its real and imaginary parts do not obey the CauchyโRiemann equations.
