๐Ÿ”— ร‰variste Galois

๐Ÿ”— Biography ๐Ÿ”— Mathematics ๐Ÿ”— France ๐Ÿ”— Biography/science and academia

ร‰variste Galois (; French: [evaสist ษกalwa]; 25 October 1811ย โ€“ 31 May 1832) was a French mathematician and political activist. While still in his teens, he was able to determine a necessary and sufficient condition for a polynomial to be solvable by radicals, thereby solving a problem that had been open for 350 years. His work laid the foundations for Galois theory and group theory, two major branches of abstract algebra.

Galois was a staunch republican and was heavily involved in the political turmoil that surrounded the French Revolution of 1830. As a result of his political activism, he was arrested repeatedly, serving one jail sentence of several months. For reasons that remain obscure, shortly after his release from prison, Galois fought in a duel and died of the wounds he suffered.

Bicameral mentality is a hypothesis introduced by Julian Jaynes who argued human ancestors as late as the ancient Greeks did not consider emotions and desires as stemming from their own minds but as the consequences of actions of gods external to themselves. The theory posits that the human mind once operated in a state in which cognitive functions were divided between one part of the brain which appears to be "speaking", and a second part which listens and obeysโ€”a bicameral mind, and that the breakdown of this division gave rise to consciousness in humans. The term was coined by Jaynes who presented the idea in his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind, wherein he made the case that a bicameral mentality was the normal and ubiquitous state of the human mind as recently as 3,000 years ago, near the end of the Mediterranean bronze age.

"We begin bombing in five minutes" is the last sentence of a controversial, off-the-record joke made by U.S. President Ronald Reagan in 1984, during the Cold War.

While preparing for a scheduled radio address from his vacation home in California, President Reagan joked with those present about outlawing and bombing Russia. This joke was not broadcast live, but was recorded and later leaked to the public. The Soviet Union criticized the president's joke, as did Reagan's opponent in the 1984 United States presidential election, Walter Mondale.

The Mummy! A Tale of the Twenty-Second Century is an 1827 three-volume novel written by Jane Webb (later Jane C. Loudon). It concerns the Egyptian mummy of Cheops, who is brought back to life in the year 2126. The novel describes a future filled with advanced technology, and was the first English-language story to feature a reanimated mummy.

After her father's death, making her an orphan at the age of 17, Webb found that:

on the winding up of his affairs that it would be necessary to do something for my support. I had written a strange, wild novel, called the Mummy, in which I had laid the scene in the twenty-second century, and attempted to predict the state of improvement to which this country might possibly arrive.

She may have drawn inspiration from the general fashion for anything pharaonic, inspired by the French researches during the Napoleonic invasion of Egypt; the 1821 public unwrappings of Egyptian mummies in a theatre near Piccadilly, which she may have attended as a girl; and, very likely, the 1818 novel by Mary Shelley, Frankenstein; or, The Modern Prometheus. As Shelley had written of Frankenstein's creation, "A mummy again endued with animation could not be so hideous as that wretch," which may have triggered her later concept. In any case, at many points she deals in greater clarity with elements from the earlier book such as the loathing for the much-desired object and the immediate arrest for crime and attempt to lie one's way out of it. However, unlike the Frankenstein monster, the hideous revived Cheops is not shuffling around dealing out horror and death, but giving canny advice on politics and life to those who befriend him. In some ways The Mummy! may be seen as her reaction to themes in Frankenstein: her mummy specifically says he is allowed life only by divine favour, rather than being indisputably vivified only by mortal science, and so on, as Hopkins' 2003 essay covers in detail.

Unlike many early science fiction works (Shelley's The Last Man, and The Reign of King George VI, 1900โ€“1925, written anonymously in 1763), Loudon did not portray the future as her own day with only political changes. She filled her world with foreseeable changes in technology, society, and even fashion. The hero, Edric Montague, lived in a peaceful and Catholic England under the rule of Queen Claudia. Her court ladies wear trousers and hair ornaments of controlled flame. Surgeons and lawyers may be steam-powered automatons. Air travel, by balloon, is commonplace. A kind of Internet is predicted in it. Besides trying to account for the revivification of the mummy in scientific termsโ€”galvanic shock rather than incantationsโ€”"she embodied ideas of scientific progress and discovery, that now read like prophecies" to those later in the 19th century. Many of the incidents in the book can be seen as satirical or humorous. Her social attitudes have resulted in this book being ranked among feminist novels.

The Mummy!: Or a Tale of the Twenty-Second Century was published anonymously in 1827 by Henry Colburn in three volumes, as was usual in that day so that each small volume could be easily carried around. It drew many favourable reviews, including one in 1829 in The Gardener's Magazine on the inventions proposed in it. In 1830, the 46-year-old reviewer, John Claudius Loudon, sought out the 22-year-old Webb, and they married the next year.

๐Ÿ”— I Am Sitting in a Room (1969)

๐Ÿ”— Electronic music

I am sitting in a room is a sound art piece composed in 1969 and one of composer Alvin Lucier's best known works.

The piece features Lucier recording himself narrating a text, and then playing the tape recording back into the room, re-recording it. The new recording is then played back and re-recorded, and this process is repeated. Due to the room's particular size and geometry, certain frequencies of the recording are emphasized while others are attenuated. Eventually the words become unintelligible, replaced by the characteristic resonant frequencies of the room itself.

In his book on the origins of minimalism, Edward Strickland wrote that "In its repetition and limited means, I am sitting in a room ranks with the finest achievements of Minimal tape music. Furthermore, in its ambient conversion of speech modules into drone frequencies, it unites the two principal structural components of Minimal music in general."

The Vespa 150 TAP was an anti-tank scooter made in the 1950s from a Vespa scooter for use with French paratroops (troupes aรฉroportรฉes, TAP). Introduced in 1956 and updated in 1959, the scooter was produced by Ateliers de Construction de Motocycles et Automobiles (ACMA), the licensed assembler of Vespas in France at the time. Modifications from the civilian Vespa included a reinforced frame and a 75ย mm (3.0ย in) recoilless rifle mounted to the scooter.

The 150 TAPs mounted a M20 75ย mm recoilless rifle, a U.S.-made light anti-armour weapon. It was very light in comparison to a standard 75ย mm (3.0ย in) cannon but was still able to penetrate 100ย mm (3.9ย in) of armour with its HEAT warhead. The recoil was counteracted by venting propellant gases out the rear of the weapon which eliminated the need for a mechanical recoil system or heavy mount.

The scooters would be parachute-dropped in pairs, accompanied by a two-man team. The gun was carried on one scooter, while the ammunition was loaded on the other. Due to the lack of any kind of aiming devices the recoilless rifle was never designed to be fired from the scooter; the gun was mounted on a M1917 Browning machine gun tripod, which was also carried by the scooter, before being fired. However, in an emergency it could be fired while in the frame, and while the scooter was moving.

The "Bazooka Vespa" was relatively cheap: Vespas cost roughly US$500 at the time, and the M20s were plentiful. 600 of them were produced, between 1956 and 1959. It had a cart, and also came with two cans of fuel.

The scooter themselves were original civilian produced VB1T models, 150 cc capacity engine. The engine was two stroke, top speed of 60ย km/h (37ย mph), enough speed to ram any vehicles if needed in an emergency, or move the user from the drop site to the area where the paratrooper was needed.

๐Ÿ”— Made in China 2025

๐Ÿ”— China ๐Ÿ”— Economics

Made in China 2025 (Chinese: ไธญๅ›ฝๅˆถ้€ 2025; pinyin: Zhลngguรณzhรฌzร o รจrlรญng'รจrwว”) (MIC25, MIC 2025, or MIC2025) is a national strategic plan and industrial policy of the Chinese Communist Party (CCP) to further develop the manufacturing sector of China, issued by CCP general secretary Xi Jinping and Chinese Premier Li Keqiang's cabinet in May 2015. As part of the Thirteenth and Fourteenth Five-year Plans, China aims to move away from being the "world's factory"โ€”a producer of cheap low-tech goods facilitated by lower labour costs and supply chain advantages. The industrial policy aims to upgrade the manufacturing capabilities of Chinese industries, growing from labor-intensive workshops into a more technology-intensive powerhouse.

Made in China 2025's goals include increasing the Chinese-domestic content of core materials to 40 percent by 2020 and 70 percent by 2025. To help achieve independence from foreign suppliers, the initiative encourages increased production in high-tech products and services, with its semiconductor industry central to the industrial plan, partly because advances in chip technology may "lead to breakthroughs in other areas of technology, handing the advantage to whoever has the best chips โ€“ an advantage that currently is out of Beijingโ€™s reach."

Since 2018, following a backlash from the U.S., Europe, and elsewhere, the phrase "MIC 2025" has been de-emphasized in government and other official communications, while the program remains in place. The Chinese government continues to invest heavily in identified technologies. In 2018, the Chinese government committed to investing roughly US$300 billion into achieving the industrial plan. In the wake of the COVID-19 pandemic, at least an additional $1.4 trillion was also invested into MIC 2025 initiatives. Given China's current middle income country status, the practicality of its disproportionate expenditure on pioneering new technologies has been called into question.

๐Ÿ”— Never Event

๐Ÿ”— Medicine

A never event is the "kind of mistake (medical error) that should never happen" in the field of medical treatment. According to the Leapfrog Group never events are defined as "adverse events that are serious, largely preventable, and of concern to both the public and health care providers for the purpose of public accountability."

A 2012 study reported there may be as many as 1,500 instances of one never event, a retained foreign object, per year in the United States. The same study suggests an estimated total of surgical mistakes at just over 4,000 per year in the United States, but these statistics are extrapolations from small samples rather than actual event counts.

Oink's Pink Palace (frequently stylized as OiNK) was a prominent BitTorrent tracker which operated from 2004 to 2007. Following a two-year investigation by the International Federation of the Phonographic Industry (IFPI) and the British Phonographic Industry (BPI), the site was shut down on 23 October 2007, by British and Dutch police agencies. These music industry organisations described OiNK as an "online pirate pre-release music club", whereas former users described it as one of the world's largest and most meticulously maintained online music repositories. About a month before the shut-down, music magazine Blender elected OiNK's creator, British software engineer Alan Ellis, to their The Powergeek 25 โ€” the Most Influential People in Online Music list. Alan Ellis was tried for conspiracy to defraud at Teesside Crown Court, the first person in the UK to be prosecuted for illegal file-sharing, and found not guilty on 15 January 2010.
