๐ Women-Are-Wonderful Effect
The women-are-wonderful effect is the phenomenon found in psychological and sociological research which suggests that people associate more positive attributes with women compared to men. This bias reflects an emotional bias toward women as a general case. The phrase was coined by Alice Eagly and Antonio Mladinic in 1994 after finding that both male and female participants tend to assign positive traits to women, with female participants showing a far more pronounced bias. Positive traits were assigned to men by participants of both genders, but to a far lesser degree.
The authors supposed that the positive general evaluation of women might derive from the association between women and nurturing characteristics. This bias is suggested as a form of misandry/'benevolent misogyny', the latter being a concept within the theoretical framework of ambivalent sexism.

๐ Fall of Saigon
The Fall of Saigon, also known as the Liberation of Saigon by North Vietnamese, was the capture of Saigon, the capital of South Vietnam, by the People's Army of Vietnam (PAVN) and the Viet Cong on 30 April 1975. The event marked the end of the Vietnam War and the start of a transition period to the formal reunification of Vietnam into the Socialist Republic of Vietnam.
The PAVN, under the command of General Vฤn Tiแบฟn Dลฉng, began their final attack on Saigon on 29 April 1975, with the Army of the Republic of Vietnam (ARVN) forces commanded by General Nguyแป n Vฤn Toร n suffering a heavy artillery bombardment. By the afternoon of the next day, the PAVN had occupied the important points of the city and raised their flag over the South Vietnamese presidential palace. The city was renamed Hแป Chรญ Minh City, after the late North Vietnamese President Hแป Chรญ Minh.
The capture of the city was preceded by Operation Frequent Wind, the evacuation of almost all American civilian and military personnel in Saigon, along with tens of thousands of South Vietnamese civilians who had been associated with the Republic of Vietnam. A few Americans chose not to be evacuated. United States ground combat units had left South Vietnam more than two years prior to the fall of Saigon and were not available to assist with either the defense of Saigon or the evacuation. The evacuation was the largest helicopter evacuation in history. In addition to the flight of refugees, the end of the war and the institution of new rules by the communists contributed to a decline in the city's population.

๐ South Georgia and the South Sandwich Islands
South Georgia and the South Sandwich Islands (SGSSI) is a British Overseas Territory in the southern Atlantic Ocean. It is a remote and inhospitable collection of islands, consisting of South Georgia Island and a chain of smaller islands known as the South Sandwich Islands. South Georgia is 165 kilometres (103ย mi) long and 35 kilometres (22ย mi) wide and is by far the largest island in the territory. The South Sandwich Islands lie about 700 kilometres (430ย mi) southeast of South Georgia. The territory's total land area is 3,903ย km2 (1,507ย sqย mi). The Falkland Islands are about 1,300 kilometres (810ย mi) west from its nearest point.
No permanent native population lives in the South Sandwich Islands, and a very small non-permanent population resides on South Georgia. There are no scheduled passenger flights or ferries to or from the territory, although visits by cruise liners to South Georgia are increasingly popular, with several thousand visitors each summer.
The United Kingdom claimed sovereignty over South Georgia in 1775 and the South Sandwich Islands in 1908. The territory of "South Georgia and the South Sandwich Islands" was formed in 1985; previously, it had been governed as part of the Falkland Islands Dependencies. Argentina claimed South Georgia in 1927 and claimed the South Sandwich Islands in 1938.
Argentina maintained a naval station, Corbeta Uruguay, on Thule Island in the South Sandwich Islands from 1976 until 1982 when it was closed by the Royal Navy. The Argentine claim over South Georgia contributed to the 1982 Falklands War, during which Argentine forces briefly occupied the island. Argentina continues to claim sovereignty over South Georgia and the South Sandwich Islands.
Toothfish are vital to the islands' economy; as a result, Toothfish Day is celebrated on 4 September as a bank holiday in the territory.

๐ Brownian Ratchet
In the philosophy of thermal and statistical physics, the Brownian ratchet or FeynmanโSmoluchowski ratchet is an apparent perpetual motion machine of the second kind, first analysed in 1912 as a thought experiment by Polish physicist Marian Smoluchowski. It was popularised by American Nobel laureate physicist Richard Feynman in a physics lecture at the California Institute of Technology on May 11, 1962, during his Messenger Lectures series The Character of Physical Law in Cornell University in 1964 and in his text The Feynman Lectures on Physics as an illustration of the laws of thermodynamics. The simple machine, consisting of a tiny paddle wheel and a ratchet, appears to be an example of a Maxwell's demon, able to extract mechanical work from random fluctuations (heat) in a system at thermal equilibrium, in violation of the second law of thermodynamics. Detailed analysis by Feynman and others showed why it cannot actually do this.

๐ Carolyn Shoemaker has died
Carolyn Jean Spellmann Shoemaker (June 24, 1929 โ August 13, 2021) was an American astronomer and a co-discoverer of Comet ShoemakerโLevyย 9. She once held the record for most comets discovered by an individual.
Although Shoemaker earned degrees in history, political science and English literature, she had little interest in science until she met and married geologist Eugene M. ("Gene") Shoemaker in 1950โ51. She later said that his explanations of his work thrilled her. Despite her relative inexperience and lack of a science degree, California Institute of Technology (Caltech) had no objection to her joining Gene's team there as a research assistant. She had already shown herself to be unusually patient, and demonstrated exceptional stereoscopic vision, which were particularly valuable qualities for looking for objects in near-Earth space.

๐ List of Countries by Vehicles per Capita
This article is a list of countries by the number of road motor vehicles per 1,000 inhabitants. This includes cars, vans, buses, and freight and other trucks; but excludes motorcycles and other two-wheelers.
China has the largest fleet of motor vehicles in the world in 2021, with 292 million cars, and in 2009 became the world's largest new car market as well. In 2011, a total of 80 million cars and commercial vehicles were built, led by China, with 18.4 million motor vehicles manufactured.
๐ Jackson structured programming
Jackson structured programming (JSP) is a method for structured programming developed by British software consultant Michael A. Jackson and described in his 1975 book Principles of Program Design. The technique of JSP is to analyze the data structures of the files that a program must read as input and produce as output, and then produce a program design based on those data structures, so that the program control structure handles those data structures in a natural and intuitive way.
JSP describes structures (of both data and programs) using three basic structures โ sequence, iteration, and selection (or alternatives). These structures are diagrammed as (in effect) a visual representation of a regular expression.

๐ Buridan's Ass
Buridan's ass is an illustration of a paradox in philosophy in the conception of free will. It refers to a hypothetical situation wherein an ass that is equally hungry and thirsty is placed precisely midway between a stack of hay and a pail of water. Since the paradox assumes the ass will always go to whichever is closer, it dies of both hunger and thirst since it cannot make any rational decision between the hay and water. A common variant of the paradox substitutes two identical piles of hay for the hay and water; the ass, unable to choose between the two, dies of hunger.
The paradox is named after the 14th-century French philosopher Jean Buridan, whose philosophy of moral determinism it satirizes. Although the illustration is named after Buridan, philosophers have discussed the concept before him, notably Aristotle, who used the example of a man equally hungry and thirsty, and Al-Ghazali, who used a man faced with the choice of equally good dates.
A version of this situation appears as metastability in digital electronics, when a circuit must decide between two states based on an input that is in itself undefined (neither zero nor one). Metastability becomes a problem if the circuit spends more time than it should in this "undecided" state, which is usually set by the speed of the clock the system is using.
๐ Richard Jewell
Richard Allensworth Jewell (born Richard White; December 17, 1962 โ August 29, 2007) was an American security guard and law enforcement officer who alerted police during the Centennial Olympic Park bombing at the 1996 Summer Olympics in Atlanta, Georgia. For months afterwards he was suspected of planting the bomb, leading to adverse publicity that "came to symbolize the excesses of law enforcement and the news media."
While working as a security guard at the Olympic Park, Jewell discovered a backpack containing three pipe bombs on the park grounds. He alerted law enforcement and helped evacuate the area before the bomb exploded, probably saving many people from injury or death.
Initially hailed by the media as a hero, Jewell was soon considered a suspect by the FBI and local law enforcement based on scientific profiling. Though never charged, he underwent a "trial by media", which took a toll on his personal and professional life. Jewell was cleared as a suspect after 88 days of public scrutiny. Eric Rudolph eventually confessed and pleaded guilty to that bombing and other attacks. The media circus surrounding the investigation, which was leaked to the press, has been widely cited as an example of law enforcement and media excesses.
In recent years, Jewell's heroic legacy has been the subject of popular culture, including the 2019 film Richard Jewell, and the drama anthology series Manhunt.
๐ Penny Universities
English coffeehouses in the 17th and 18th centuries were public social places where men would meet for conversation and commerce. For the price of a penny, customers purchased a cup of coffee and admission. Travellers introduced coffee as a beverage to England during the mid-17th century; previously it had been consumed mainly for its supposed medicinal properties. Coffeehouses also served tea and hot chocolate as well as a light meal.
The historian Brian Cowan describes English coffeehouses as "places where people gathered to drink coffee, learn the news of the day, and perhaps to meet with other local residents and discuss matters of mutual concern." Topics like the Yellow Fever would also be discussed. The absence of alcohol created an atmosphere in which it was possible to engage in more serious conversation than in an alehouse. Coffeehouses also played an important role in the development of financial markets and newspapers.
Topics discussed included politics and political scandals, daily gossip, fashion, current events, and debates surrounding philosophy and the natural sciences. Historians often associate English coffeehouses, during the 17th and 18th centuries, with the intellectual and cultural history of the Age of Enlightenment: they were an alternate sphere, supplementary to the university. Political groups frequently used coffeehouses as meeting places.
