🔗 Biography 🔗 Medicine 🔗 COVID-19 🔗 China 🔗 Biography/science and academia

Li Wenliang (Chinese: 李文亮; pinyin: Lǐ Wénliàng; 12 October 1986 – 7 February 2020) was a Chinese ophthalmologist who worked as a physician at Wuhan Central Hospital. Li warned his colleagues in December 2019 about a possible outbreak of an illness that resembled severe acute respiratory syndrome (SARS), later acknowledged as COVID-19. He became a whistleblower when his warnings were later shared publicly. On 3 January 2020, Wuhan police summoned and admonished him for "making false comments on the Internet". Li returned to work, later contracted the virus from an infected patient (who had been originally treated for glaucoma) and died from the disease on 7 February 2020, at age 33. A subsequent Chinese official inquiry exonerated him and the Communist Party formally offered a "solemn apology" to his family and revoked its admonishment of him.

🔗 Antarctica 🔗 Transport

The Antarctic Snow Cruiser was a vehicle designed from 1937 to 1939 under the direction of Thomas Poulter, intended to facilitate transport in Antarctica during the United States Antarctic Service Expedition (1939–41). The Snow Cruiser was also known as "The Penguin," "Penguin 1" or "Turtle" in some published material.

Poulter had been second in command of Byrd's Second Antarctic Expedition, launched in 1934. From his time in the Antarctic, Poulter had devised several innovative features. However, the massive Snow Cruiser generally failed to operate as hoped under the difficult conditions, and was eventually abandoned in Antarctica. Rediscovered under a deep layer of snow in 1958, it later disappeared again due to shifting ice conditions.

🔗 Novels

Celine's Laws are a series of three laws regarding government and social interaction attributed to the fictional character Hagbard Celine from Robert Anton Wilson's and Robert Shea's Illuminatus! Trilogy. Celine, a gentleman anarchist, serves as a mouthpiece for Wilson's libertarian, anarchist and sometimes completely uncategorizable ideas about the nature of humanity. Celine's Laws are outlined in the trilogy by a manifesto titled Never Whistle While You're Pissing. Wilson later goes on to elaborate on the laws in his nonfiction book, Prometheus Rising, as being inherent consequences of average human psychology.

A piece entitled Celine's Laws appears in Robert Anton Wilson's The Illuminati Papers, which features articles written by Wilson under the guise of many of his characters from The Illuminatus! Trilogy alongside interviews with the author himself. One article pulls from another, as well as from the original Trilogy.

Celine, in his manifesto, recognizes these are generalities, but also says that their basic principles can be used to find the source of every great decline and fall of nations, and goes on to claim they are as universal as Newton's Laws in applying to everything.

🔗 China 🔗 Politics

Document Number Nine (or Document No. 9), more properly the Communiqué on the Current State of the Ideological Sphere (also translated as the Briefing on the Current Situation in the Ideological Realm), is a confidential internal document widely circulated within the Communist Party of China in 2013 by the General Office of the Communist Party of China. The document was first circulated in July 2012. The document warns of seven dangerous Western values, allegedly including media freedom and judicial independence. Teaching on any of the seven topics is forbidden. There is an emphasis on controlling and preventing communication using the internet of ideas subversive to one party rule. The document was issued in the context of planned economic reforms and increased calls for political reform. It has been described as a critique of the "liberal ways of thinking".

The document was not made available to public by the Communist Party or any branches of the Chinese government, but in July 2013 was allegedly leaked by Chinese dissident journalist Gao Yu, who was in turn sentenced to a seven-year imprisonment for "leaking state secrets".

It is unclear whether this document is official Chinese policy or just a faction within the party. However, The New York Times suggests that it "bears the unmistakable imprimatur of Xi Jinping". It is thought that Document No. 9 was issued by the Central Committee General Office, and would have required the approval of Mr. Xi and other top leaders. A severe crackdown against human rights lawyers, media outlets, academics, and other such independent thinkers has followed the document's publication.

🔗 Psychology 🔗 Education

Bloom's 2 sigma problem refers to an educational phenomenon observed by educational psychologist Benjamin Bloom and initially reported in 1984 in the journal Educational Researcher. Bloom found that the average student tutored one-to-one using mastery learning techniques performed two standard deviations better than students who learn via conventional instructional methods — that is, "the average tutored student was above 98% of the students in the control class". Additionally, the variation of the students' achievement changed: "about 90% of the tutored students ... attained the level of summative achievement reached by only the highest 20%" of the control class. Bloom's graduate students J. Anania and A. J. Burke conducted studies of this effect at different grade levels and in different schools, observing students with "great differences in cognitive achievement, attitudes, and academic self-concept".

🔗 Books 🔗 Psychology

The Myth of Mental Illness: Foundations of a Theory of Personal Conduct is a 1961 book by the psychiatrist Thomas Szasz, in which the author criticizes psychiatry and argues against the concept of mental illness. It received much publicity, and has become a classic, well known as an argument that "mentally ill" is a label which psychiatrists have used against people "disabled by living" rather than truly having a disease.

🔗 Technology 🔗 Computing 🔗 Electronics

A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, there are supercomputers which can perform over a hundred quadrillion FLOPS (petaFLOPS). Since November 2017, all of the world's fastest 500 supercomputers run Linux-based operating systems. Additional research is being conducted in China, the United States, the European Union, Taiwan and Japan to build faster, more powerful and technologically superior exascale supercomputers.

Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in various fields, including quantum mechanics, weather forecasting, climate research, oil and gas exploration, molecular modeling (computing the structures and properties of chemical compounds, biological macromolecules, polymers, and crystals), and physical simulations (such as simulations of the early moments of the universe, airplane and spacecraft aerodynamics, the detonation of nuclear weapons, and nuclear fusion). They have been essential in the field of cryptanalysis.

Supercomputers were introduced in the 1960s, and for several decades the fastest were made by Seymour Cray at Control Data Corporation (CDC), Cray Research and subsequent companies bearing his name or monogram. The first such machines were highly tuned conventional designs that ran faster than their more general-purpose contemporaries. Through the decade, increasing amounts of parallelism were added, with one to four processors being typical. From the 1970s, vector processors operating on large arrays of data came to dominate. A notable example is the highly successful Cray-1 of 1976. Vector computers remained the dominant design into the 1990s. From then until today, massively parallel supercomputers with tens of thousands of off-the-shelf processors became the norm.

The US has long been the leader in the supercomputer field, first through Cray's almost uninterrupted dominance of the field, and later through a variety of technology companies. Japan made major strides in the field in the 1980s and 90s, with China becoming increasingly active in the field. As of November 2018, the fastest supercomputer on the TOP500 supercomputer list is the Summit, in the United States, with a LINPACK benchmark score of 143.5 PFLOPS, followed by, Sierra, by around 48.860 PFLOPS. The US has five of the top 10 and China has two. In June 2018, all supercomputers on the list combined broke the 1 exaFLOPS mark.

🔗 Sociology

The Matthew effect of accumulated advantage, Matthew principle, or Matthew effect for short, is sometimes summarized by the adage "the rich get richer and the poor get poorer". The concept is applicable to matters of fame or status, but may also be applied literally to cumulative advantage of economic capital. In the beginning, Matthew effects were primarily focused on the inequality in the way scientists were recognized for their work. However, Norman Storer, of Columbia University, led a new wave of research. He believed he discovered that the inequality that existed in the social sciences also existed in other institutions.

The term was coined by sociologist Robert K. Merton in 1968 and takes its name from the Parable of the talents or minas in the biblical Gospel of Matthew. Merton credited his collaborator and wife, sociologist Harriet Zuckerman, as co-author of the concept of the Matthew effect.

🔗 Video games 🔗 Computing

The ZX81 is a home computer that was produced by Sinclair Research and manufactured in Dundee, Scotland, by Timex Corporation. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and designed to be a low-cost introduction to home computing for the general public. It was hugely successful; more than 1.5 million units were sold. In the United States it was initially sold as the ZX-81 under license by Timex. Timex later produced its own versions of the ZX81: the Timex Sinclair 1000 and Timex Sinclair 1500. Unauthorized ZX81 clones were produced in several countries.

The ZX81 was designed to be small, simple, and above all, inexpensive, with as few components as possible. Video output is to a television set rather than a dedicated monitor. Programs and data are loaded and saved onto compact audio cassettes. It uses only four silicon chips and a mere 1 KB of memory. There is no power switch or any moving parts with the exception of a VHF TV channel selector switch present in some models. It has a pressure-sensitive membrane keyboard. The ZX81's limitations prompted a market in third-party peripherals to improve its capabilities. Its distinctive case and keyboard brought designer Rick Dickinson a Design Council award.

The ZX81 could be bought by mail order preassembled or, for a lower price, in kit form. It was the first inexpensive mass-market home computer to be sold by high street stores, led by W. H. Smith and soon many other retailers. The ZX81 marked the point when computing in Britain became an activity for the general public rather than the preserve of businessmen and electronics hobbyists. It produced a huge community of enthusiasts, some of whom founded their own businesses producing software and hardware for the ZX81. Many went on to play major roles in the British computer industry. The ZX81's commercial success made Sinclair Research one of Britain's leading computer manufacturers and earned a fortune and an eventual knighthood for the company's founder Sir Clive Sinclair.

🔗 China 🔗 Economics

Tang ping (Chinese: 躺平; pinyin: tǎng píng; lit. 'lying flat') is a lifestyle choice and social protest movement in China by some young people who reject societal pressures on hard work or even overwork (such as the 996 working hour system, which is generally regarded as a rat race with ever diminishing returns), and instead choose to "lie down flat and get over the beatings" via a low-desire, more indifferent attitude towards life. Novelist Liao Zenghu described "lying flat" as a resistance movement, and The New York Times called it part of a nascent Chinese counterculture. It has also been compared to the Great Resignation that began in America (and the western world) around the same time.

Unlike the hikikomori in Japan (who are socially withdrawn), these young Chinese people who subscribe to "lying flat" are not socially isolated, but merely choose to lower their professional and economic ambitions and simplify their goals, still being fiscally productive for their own essential needs, and prioritize psychological health over economic materialism.
