At the time Recorde proposed this notation, there was no easy way of denoting the powers of numbers other than squares and cubes. The root word for Recorde's notation is zenzic, which is a German spelling of the medieval Italian word censo, meaning "squared". Since the square of a square of a number is its fourth power, Recorde used the word zenzizenzic (spelled by him as zenzizenzike) to express it. Some of the terms had prior use in Latin "zenzicubicus", "zensizensicus" and "zensizenzum". Similarly, as the sixth power of a number is equal to the square of its cube, Recorde used the word zenzicubike to express it; a more modern spelling, zenzicube, is found in Samuel Jeake's Logisticelogia. Finally, the word zenzizenzizenzic denotes the square of the square of a number's square, which is its eighth power: in modern notation,
Recorde proposed three mathematical terms by which any power (that is, index or exponent) greater than 1 could be expressed: zenzic, i.e. squared; cubic; and sursolid, i.e. raised to a prime number greater than three, the smallest of which is five. Sursolids were as follows: 5 was the first; 7, the second; 11, the third; 13, the fourth; etc.
Therefore, a number raised to the power of six would be zenzicubic, a number raised to the power of seven would be the second sursolid, hence bissursolid (not a multiple of two and three), a number raised to the twelfth power would be the "zenzizenzicubic" and a number raised to the power of ten would be the square of the (first) sursolid. The fourteenth power was the square of the second sursolid, and the twenty-second was the square of the third sursolid.
Curiously, Jeake's text appears to designate a written exponent of 0 as being equal to an "absolute number, as if it had no Mark", thus using the notation x0 to refer to x alone, while a written exponent of 1, in his text, denotes "the Root of any number", thus using the notation x1 to refer to what is now known to be x0.5.
The word, as well as the system, is obsolete except as a curiosity; the Oxford English Dictionary (OED) has only one citation for it. As well as being a mathematical oddity, it survives as a linguistic oddity: zenzizenzizenzic has more Zs than any other word in the OED.
Samuel Jeake the Younger gives zenzizenzizenzizenzike (the square of the square of the square of the square, or 16th power) in a table in A Compleat Body of Arithmetick:
Numerous reasons have been given by different people for the 2026 Iran war, which began when the United States and Israel launched surprise airstrikes on Iran on 28 February 2026. The reasons are described as diverse, changing, and at times contradictory.
US and Israeli officials have framed it as a preemptive war of self-defense. They argue that diplomacy had failed to contain the unacceptable and potentially existential threats of Iran's nuclear program and ballistic missiles. They also argued the strikes were justified as a response to Iran's regional activities (support for proxy groups, attacks on shipping, etc.) and its violent suppression of domestic protests in January 2026. Critics have described it as a war of choice. Some analysts describe the war as a classic "security dilemma", where both sides saw the other's military buildup as threatening, making conflict increasingly likely even if neither side necessarily wanted full-scale war. Regional actors, like Saudi Arabia and the United Arab Emirates, share many of the US and Israel's war aims though differing on whether to pursue war or diplomacy.
In times when women had a prescribed role, burrnesha gave up their preexisting sexual, reproductive and social identities to acquire the same freedoms as men. They could dress as men, be head of the household, move freely in social situations, and take work traditionally open only to men. National Geographic's Taboo estimated in 2002 that there were fewer than 102 Albanian sworn virgins left. As of 2022, while there were no exact figures, twelve burrnesha were estimated to remain in Northern Albania and Kosovo.
The impossibility of squaring the circle using only compass and straightedge constructions, suspected since ancient times, was rigorously proven in 1882 by Ferdinand von Lindemann. Better approximations of π than those implied by the bill have been known since ancient times.
It won a Hugo Award in 1968. The name was also used for a short story collection of Ellison's work, featuring this story. It was reprinted by the Library of America, collected in volume two (Terror and the Uncanny, from the 1940s to Now) of American Fantastic Tales.
The "fruit machine" was employed in Canada in the 1950s and 1960s during a campaign to eliminate all gay men from the civil service, the Royal Canadian Mounted Police (RCMP), and the military. A substantial number of workers did lose their jobs. Although funding for the "fruit machine" project was cut off in the late 1960s, the investigations continued, and the RCMP collected files on over 9,000 "suspected" gay people.
The chair employed resembled that used by dentists. It had a pulley with a camera going towards the pupils, with a black box located in front of it that displayed pictures. The pictures ranged from the mundane to sexually explicit photos of men and women. It had previously been determined that the pupils would dilate in relation to the amount of interest in the picture per the technique termed 'the pupillary response test'.
People were first led to believe that the machine's purpose was to rate stress. After knowledge of its real purpose became widespread, few people volunteered for it.
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.
The U.S. Army Corps of Engineers Bay Model is a working hydraulic scale model of the San Francisco Bay and Sacramento-San Joaquin River Delta System. While the Bay Model is still operational, it is no longer used for scientific research but is instead open to the public alongside educational exhibits about Bay hydrology. The model is located in the Bay Model Visitor Center at 2100 Bridgeway Blvd. in Sausalito, California.
The Caerphilly Heart Disease Study, also known as the Caerphilly Prospective Study (CaPS), is an epidemiological prospective cohort, set up in 1979 in a representative population sample drawn from Caerphilly, a typical small town in South Wales, UK.
The initial aim was to examine relationships between a wide range of social, lifestyle, dietary and other factors with incident vascular disease. Opportunity was also taken, in collaboration with a range of clinical and laboratory colleagues, to collect data on a wide range of factors with possible relevance to diseases other than vascular, and at the same time to collect clinical information on incident disease events. The study was initiated by Professor Peter Elwood, Director of the Medical Research Council (MRC) Epidemiology Unit for South Wales. The work has so far led to over 400 publications in the medical press.
Inferno is the fifth studio album by Scottish electronic music duo Boards of Canada, released on 29 May 2026 by Warp. It marks the duo's first studio album in thirteen years, following Tomorrow's Harvest (2013). An ambient and electronic album described as hauntology and IDM, the album was noted as the duo's response to a darker zeitgeist. Its instrumentation contains guitars, live drums, and synths, adopting a live sound. Recorded at Hexagon Sun studio in Pentland Hills, Scotland, both members are credited on the album as instrumentalists and sound designers; writing and production is credited solely to Mike Sandison.
The promotional campaign began in April 2026, with VHS tapes being mailed out to fans, and the track "Tape 05" being shared online later that month before the album was properly announced. The single "Introit / Prophecy at 1420 MHz" was released in early May, accompanied by a music video directed by Robert Beatty. Listening sessions occurred in various places across the world later that month. A day prior to release, use of the album's music and aesthetic was co-opted by the White House, which was received negatively by the public and denounced by Warp. Anticipated widely for release, Inferno received praise as a relevant return for Boards of Canada, and for its subject matter, musicality, and thematic content.
The Phaistos Disc (also spelled Phaistos Disk, Phaestos Disc) is a disk of fired clay from the Minoan palace of Phaistos on the island of Crete, possibly dating to the middle or late Minoan Bronze Age (second millennium B.C.). The disk is about 15 cm (5.9 in) in diameter and covered on both sides with a spiral of stamped symbols. Its purpose and meaning, and even its original geographical place of manufacture, remain disputed, making it one of the most famous mysteries of archaeology. This unique object is now on display at the archaeological museum of Heraklion.
The disc was discovered in 1908 by the Italian archaeologist Luigi Pernier in the Minoan palace-site of Phaistos, and features 241 tokens, comprising 45 distinct signs, which were apparently made by pressing hieroglyphic "seals" into a disc of soft clay, in a clockwise sequence spiraling toward the center of the disk.
The Phaistos Disc captured the imagination of amateur and professional archaeologists, and many attempts have been made to decipher the code behind the disc's signs. While it is not clear that it is a script, most attempted decipherments assume that it is; most additionally assume a syllabary, others an alphabet or logography. Attempts at decipherment are generally thought to be unlikely to succeed unless more examples of the signs are found, as it is generally agreed that there is not enough context available for a meaningful analysis.
Although the Phaistos Disc is generally accepted as authentic by archaeologists, a few scholars believe that the disc is a forgery or a hoax.
Research at Stanford University helped incorporate the concept into supply chain vernacular using a story about Volvo. Suffering a glut in green cars, sales and marketing developed a program to sell the excess inventory. While successful in generating the desired market pull, manufacturing did not know about the promotional plans. Instead, they read the increase in sales as an indication of growing demand for green cars and ramped up production.
Research indicates a fluctuation in point-of-sale demand of five percent will be interpreted by supply chain participants as a change in demand of up to forty percent. Much like cracking a whip, a small flick of the wrist - a shift in point of sale demand - can cause a large motion at the end of the whip - manufacturers' responses.
On 17 August 2009, the Swedish newspaper Aftonbladet published an article reporting how Israel stole the organs of Palestinians in custody. Before eventually admitting to theft of organs, the Israeli government initially denied the allegations and called them antisemetic. The Swedish government refused to condemn the article, and upheld Aftonbladet's freedom of speech, leading to a rift between the Swedish and the Israeli governments. Palestinian officials and families of the deceased called for an independent investigation. In December 2009, Israeli officials admitted that they had harvested the organs of Palestinians without their families' permission. These Palestinians had been killed by the Israeli military, but Israeli officials emphasized they did not kill Palestinians in order to harvest their organs.
The article that sparked the controversy was written by Swedish freelance photojournalist Donald Boström, with the title Våra söner plundras på sina organ ("Our sons are being plundered for their organs"). It presented allegations that in the late 1980s and the early 1990s, many young men from the West Bank and Gaza Strip had been seized by Israeli forces and their bodies returned to their families with organs missing. It was published by Aftonbladet, one of the largest daily newspapers in the Nordic countries.
The Israeli government and several US representatives claimed that the article was baseless and incendiary, alluding to the history of antisemitism and blood libels against Jews, and asked the Swedish government to denounce the article. The government refused, citing freedom of the press and the Swedish constitution. Swedish ambassador to Israel Elisabet Borsiin Bonnier condemned the article as "shocking and appalling" and stated that freedom of the press carries responsibility, but the Swedish government distanced itself from her remarks. The Swedish Newspaper Publishers' Association and Reporters Without Borders supported Sweden's refusal to condemn it. The former warned of venturing onto a slope with government officials damning occurrences in Swedish media, which may curb warranted debate and restrain freedom of expression by self-censorship. Italy made a stillborn attempt to defuse the diplomatic situation by a European resolution condemning antisemitism. A survey among the cultural editors of the other major Swedish newspapers found that all would have refused the article. The Palestinian National Authority announced that it would establish a commission to investigate the article's claims.
In December 2009, a 2000 interview with the chief pathologist at the L. Greenberg National Institute of Forensic Medicine Yehuda Hiss was released in which he had admitted taking organs from the corpses of Israelis, Palestinians and foreign workers without their families' permission. Israeli health officials confirmed Hiss's confession but stated that such incidents had ended in the 1990s and noted that Hiss had been removed from his post. The Palestinian press said the report "appeared to confirm Palestinians' allegations that Israel returned their relatives' bodies with their chests sewn up, having harvested their organs". Several news agencies claimed the Aftonbladet article accused Israel of killing Palestinians to harvest their organs, although the author, the culture editor for Aftonbladet, and Nancy Scheper-Hughes denied that it had made that claim.
The Liverpool and Manchester Railway (L&MR) was the first inter-city railway in the world. It opened on 15 September 1830 between the Lancashire towns of Liverpool and Manchester in England. It was also the first railway to rely exclusively on locomotives driven by steam power, with no horse-drawn traffic permitted at any time; the first to be entirely double track throughout its length; the first to have a true signalling system; the first to be fully timetabled; and the first to carry mail.
Trains were hauled by company steam locomotives between the two towns, though private wagons and carriages were allowed. Cable haulage of freight trains was down the steeply-graded 1.26-mile (2.03 km) Wapping Tunnel to Liverpool Docks from Edge Hill junction. The railway was primarily built to provide faster transport of raw materials, finished goods, and passengers between the Port of Liverpool and the cotton mills and factories of Manchester and surrounding towns.
Designed and built by George Stephenson, the line was financially successful, and influenced the development of railways across Britain in the 1830s. In 1845, the railway was absorbed by its principal business partner, the Grand Junction Railway (GJR), which in turn amalgamated the following year with the London and Birmingham Railway and the Manchester and Birmingham Railway to form the London and North Western Railway.
