Creeping normality (also called landscape amnesia) is a process by which a major change can be accepted as normal and acceptable if it happens slowly through small, often unnoticeable, increments of change. The change could otherwise be regarded as objectionable if it took place in a single step or short period.

American scientist, Jared Diamond, first coined the phrase creeping normality in his 2005 book, Collapse: How Societies Choose to Fail or Succeed. Prior to releasing his book, Diamond explored this theory while attempting to explain why, in the course of long-term environmental degradation, Easter Island natives would, seemingly irrationally, chop down the last tree:

"I suspect, though, that the disaster happened not with a bang but with a whimper. After all, there are those hundreds of abandoned statues to consider. The forest the islanders depended on for rollers and rope didn't simply disappear one day—it vanished slowly, over decades."

The Tulsa race massacre (also called the Tulsa race riot, the Greenwood Massacre, or the Black Wall Street Massacre) of 1921 took place on May 31 and June 1, 1921, when mobs of white residents attacked black residents and businesses of the Greenwood District in Tulsa, Oklahoma. It has been called "the single worst incident of racial violence in American history." The attack, carried out on the ground and from private aircraft, destroyed more than 35 square blocks of the district – at that time the wealthiest black community in the United States, known as "Black Wall Street".

More than 800 people were admitted to hospitals and as many as 6,000 black residents were interned at large facilities, many for several days. The Oklahoma Bureau of Vital Statistics officially recorded 36 dead, but the American Red Cross declined to provide an estimate. A 2001 state commission examination of events was able to confirm 39 dead, 26 black and 13 white, based on contemporary autopsy reports, death certificates and other records. The commission gave overall estimates from 75–100 to 150–300 dead.

The massacre began over Memorial Day weekend after 19-year-old Dick Rowland, a black shoeshiner, was accused of assaulting Sarah Page, the 17-year-old white elevator operator of the nearby Drexel Building. He was taken into custody. A subsequent gathering of angry local whites outside the courthouse where Rowland was being held, and the spread of rumors he had been lynched, alarmed the local black population, some of whom arrived at the courthouse armed. Shots were fired and twelve people were killed: ten white and two black. As news of these deaths spread throughout the city, mob violence exploded. White rioters rampaged through the black neighborhood that night and morning killing men and burning and looting stores and homes, and only around noon the next day Oklahoma National Guard troops managed to get control of the situation by declaring martial law. About 10,000 black people were left homeless, and property damage amounted to more than $1.5 million in real estate and $750,000 in personal property (equivalent to $32.25 million in 2019).

Many survivors left Tulsa. Black and white residents who stayed in the city were silent for decades about the terror, violence, and losses of this event. The massacre was largely omitted from local, state, and national histories.

In 1996, seventy-five years after the massacre, a bipartisan group in the state legislature authorized formation of the Oklahoma Commission to Study the Tulsa Race Riot of 1921 (renamed Oklahoma Commission to Study the Tulsa Race Massacre, in November 2018). Members were appointed to investigate events, interview survivors, hear testimony from the public, and prepare a report of events. There was an effort toward public education about these events through the process. The Commission's final report, published in 2001, said that the city had conspired with the mob of white citizens against black citizens; it recommended a program of reparations to survivors and their descendants. The state passed legislation to establish some scholarships for descendants of survivors, encourage economic development of Greenwood, and develop a memorial park in Tulsa to the massacre victims. The park was dedicated in 2010. In 2020, the massacre became part of the Oklahoma school curriculum.

🔗 Philosophy 🔗 Philosophy/Logic

In logic, a many-valued logic (also multi- or multiple-valued logic) is a propositional calculus in which there are more than two truth values. Traditionally, in Aristotle's logical calculus, there were only two possible values (i.e., "true" and "false") for any proposition. Classical two-valued logic may be extended to n-valued logic for n greater than 2. Those most popular in the literature are three-valued (e.g., Łukasiewicz's and Kleene's, which accept the values "true", "false", and "unknown"), the finite-valued (finitely-many valued) with more than three values, and the infinite-valued (infinitely-many-valued), such as fuzzy logic and probability logic.

On 11 March 2022, Mark Izraylevich Bernstein (Russian: Марк Израйлевич Бернштейн), a Belarusian blogger and editor of the Russian-language Wikipedia based in Minsk, was detained by the Belarusian GUBOPiK security force after online accusations of violating the 2022 Russian fake news law for his editing of Wikipedia articles on the topic of the 2022 Russian invasion of Ukraine. He was sentenced to 15 days' administrative arrest under Article 24.3 of the Administrative Code of Belarus (for disobedience to police officers).

🔗 Jazz

The Real Book is a musicians' fake book – a compilation of lead sheets for jazz standards. Fake books had been around at least since the late 1920s, but their organization was haphazard, and their content did not always keep pace with contemporary musical styles. The Real Book was initially produced by two students at the Berklee College of Music in the 1970s, as an updated fake book. It became so popular that the books was eventually "legitimized" by publisher Hal Leonard, and re-released in a series of editions and transpositions for various instruments.

🔗 Physics

A Halbach array (German: [ˈhalbax]) is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. This is achieved by having a spatially rotating pattern of magnetisation.

The rotating pattern of permanent magnets (on the front face; on the left, up, right, down) can be continued indefinitely and have the same effect. The effect of this arrangement is roughly similar to many horseshoe magnets placed adjacent to each other, with similar poles touching.

This magnetic orientation process replicates that applied by a magnetic recording tape head to the magnetic tape coating during the recording process. The principle was further described by James (Jim) M. Winey of Magnepan in 1970, for the ideal case of continuously rotating magnetization, induced by a one-sided stripe-shaped coil.

The effect was also discovered by John C. Mallinson in 1973, and these "one-sided flux" structures were initially described by him as a "curiosity", although at the time he recognized from this discovery the potential for significant improvements in magnetic tape technology.

Physicist Klaus Halbach, while at the Lawrence Berkeley National Laboratory during the 1980s, independently invented the Halbach array to focus particle accelerator beams.

On the x86 computer architecture, a triple fault is a special kind of exception generated by the CPU when an exception occurs while the CPU is trying to invoke the double fault exception handler, which itself handles exceptions occurring while trying to invoke a regular exception handler.

x86 processors beginning with the 80286 will cause a shutdown cycle to occur when a triple fault is encountered. This typically causes the motherboard hardware to initiate a CPU reset, which, in turn, causes the whole computer to reboot.

A red herring is something that misleads or distracts from a relevant or important question. It may be either a logical fallacy or a literary device that leads readers or audiences toward a false conclusion. A red herring may be used intentionally, as in mystery fiction or as part of rhetorical strategies (e.g., in politics), or may be used in argumentation inadvertently.

The term was popularized in 1807 by English polemicist William Cobbett, who told a story of having used a strong-smelling smoked fish to divert and distract hounds from chasing a rabbit.

Abram Petrovich Gannibal, also Hannibal or Ganibal, or Abram Hannibal or Abram Petrov (Russian: Абра́м Петро́вич Ганниба́л; c. 1696 – 14 May 1781), was a Russian military engineer, major-general, and nobleman of African origin. Kidnapped as a child, Gannibal was taken to Russia and presented as a gift to Peter the Great, where he was freed, adopted and raised in the Emperor's court household as his godson.

Gannibal eventually rose to become a prominent member of the imperial court in the reign of Peter's daughter Elizabeth. He had 11 children, most of whom became members of the Russian nobility; he was a great-grandfather of the author and poet Alexander Pushkin.
