Emma Rowena (Caldwell) Gatewood, known as Grandma Gatewood, (October 25, 1887 – June 4, 1973), was an American ultra-light hiking pioneer. After a difficult life as a farm wife, mother of eleven children, and survivor of domestic violence, she became famous as the first solo female thru-hiker of the 2,168-mile (3,489 km) Appalachian Trail (A.T.) in 1955 at the age of 67. She subsequently became the first person (male or female) to hike the A.T. three times, after completing a second thru-hike two years later, followed by a section-hike in 1964. In the meantime, she hiked 2,000 miles (3,200 km) of the Oregon Trail in 1959. In her later years, she continued to travel and hike, and worked on a section of what would become the Buckeye Trail. The media coverage surrounding her feats was credited for generating interest in maintaining the A.T. and in hiking generally. Among many other honors, she was posthumously inducted into the Appalachian Trail Hall of Fame in 2012.

The Magdeburg Water Bridge (German: Kanalbrücke Magdeburg) is a large navigable aqueduct in central Germany, located near Magdeburg. The largest canal underbridge in Europe, it spans the river Elbe and directly connects the Mittellandkanal to the west and Elbe-Havel Canal to the east of the river, allowing large commercial ships to pass between the Rhineland and Berlin without having to descend into and then climb out of the Elbe itself.

🔗 Mathematics 🔗 Statistics

Anscombe's quartet comprises four data sets that have nearly identical simple descriptive statistics, yet have very different distributions and appear very different when graphed. Each dataset consists of eleven (x,y) points. They were constructed in 1973 by the statistician Francis Anscombe to demonstrate both the importance of graphing data when analyzing it, and the effect of outliers and other influential observations on statistical properties. He described the article as being intended to counter the impression among statisticians that "numerical calculations are exact, but graphs are rough."

🔗 Politics

In political jargon, a self-licking ice cream cone is a self-perpetuating system that has no purpose other than to sustain itself. The phrase appeared to have been first used in 1992, in On Self-Licking Ice Cream Cones, a paper by Pete Worden about NASA's bureaucracy. James A. Vedda described it as "Why do humans go into space? So we can go farther into space!"

Since then, the term has been used to describe the habit of government funded organisations and programs spending taxpayer money to lobby for more funding from the taxpayer. Other things compared have included financial bubbles, chatshows and reality television. In The Irish Times, Kevin Courtney observed that "many organisations are also stuck in limbo, destined to keep lurching on without ever achieving their stated goal. That’s because their real goal is simply to carry on regardless." The Cold War infrastructure has also been compared to a self-licking ice cream cone, given that expensive projects continued to be financed long after world communism had ceased to pose a viable threat.

Richard Hoggart used the term to describe certain United Nations programmes.

In sport, the Bowl Alliance was criticised using the term.

Taqi al-Din Muhammad ibn Ma'ruf ash-Shami al-Asadi (Arabic: تقي الدين محمد بن معروف الشامي‎, Ottoman Turkish: تقي الدين محمد بن معروف الشامي السعدي‎, Turkish: Takiyüddin) (1526-1585) was an Ottoman polymath active in Cairo and Istanbul. He was the author of more than ninety books on a wide variety of subjects, including astronomy, clocks, engineering, mathematics, mechanics, optics and natural philosophy.

In 1574 the Ottoman Sultan Murad III invited Taqī ad-Dīn to build the Constantinople observatory. Using his exceptional knowledge in the mechanical arts, Taqī ad-Dīn constructed instruments like huge armillary and mechanical clocks that he used in his observations of the Great Comet of 1577. He also used European celestial and terrestrial globes that were delivered to Istanbul in gift-exchange.

The major work that resulted from his work in the observatory is titled "The tree of ultimate knowledge [in the end of time or the world] in the Kingdom of the Revolving Spheres: The astronomical tables of the King of Kings [Murād III]" (Sidrat al-muntah al-afkar fi malkūt al-falak al-dawār– al-zij al-Shāhinshāhi). The work was prepared according to the results of the observations carried out in Egypt and Istanbul in order to correct and complete Ulugh Beg's Zij as-Sultani. The first 40 pages of the work deal with calculations, followed by discussions of astronomical clocks, heavenly circles, and information about three eclipses which he observed at Cairo and Istanbul. For corroborating data of other observations of eclipses in other locales like Daud ar-Riyyadi (David the Mathematician), David Ben-Shushan of Salonika.

As a polymath, Taqī al-Dīn wrote numerous books on astronomy, mathematics, mechanics, and theology. His method of finding coordinates of stars were reportedly so precise that he got better measurements than his contemporaries, Tycho Brahe and Nicolas Copernicus. Brahe is also thought to have been aware of al-Dīn's work.

Taqī Ad-Dīn also described a steam turbine with the practical application of rotating a spit in 1551. He worked on and created astronomical clocks for his observatory. Taqī Ad-Dīn also wrote a book on optics, in which he determined the light emitted from objects, proved the Law of Reflection observationally, and worked on refraction.

🔗 United States 🔗 Finance & Investment

The term 3-6-3 Rule describes how the United States retail banking industry operated from the 1950s to the 1980s. The name 3-6-3 refers to the impression that bankers had a stable, comfortable existence by paying 3 percent interest on deposits, lending money out at 6 percent, and being able to "tee off at the golf course by 3 p.m."

The implication was that the banks were less competitive during that period than in subsequent years due to tight regulations that limited the formation and location of banks as well as restrictions on interest rates that could be charged or paid. As a result, bankers had "power and prestige ... while profits were steady and certain". These regulations were loosened in the 1980s.

Richmond Federal Reserve senior economist John R. Walter argues that, although there is evidence that restrictions on banks before the 1980s did limit the competitiveness of banking markets and thereby granted some banks monopoly power, "the regulatory restrictions probably had a limited effect on competition" during the time in question. Chicago Federal Reserve researchers Robert DeYoung and Tara Rice argue that, "Like most good jokes, the 3-6-3 rule mixes a grain of truth with a highly simplified view of reality."

The rule has been noted positively following the late-2000s financial crisis as a preferable way for banks to operate following the bailout of major banks.

Australia's banking system, which was deregulated in the 1990s in a manner similar to that in the U.S., also came to be characterized in the same way as did the United Kingdom's.

🔗 Languages 🔗 Ottoman Empire 🔗 Western Asia

The language of the court and government of the Ottoman Empire was Ottoman Turkish, but many other languages were in contemporary use in parts of the empire. Although the minorities of the Ottoman Empire were free to use their language amongst themselves, if they needed to communicate with the government they had to use Ottoman Turkish.

The Ottomans had three influential languages: Turkish, spoken by the majority of the people in Anatolia and by the majority of Muslims of the Balkans except in Albania, Bosnia, and various Aegean Sea islands; Persian, initially used by the educated in northern portions of the Ottoman Empire before being displaced by Ottoman Turkish; and Arabic, used in southern portions of the Ottoman Empire; Arabic was spoken mainly in Arabia, North Africa, Mesopotamia and the Levant. Throughout the vast Ottoman bureaucracy Ottoman Turkish language was the official language, a version of Turkish, albeit with a vast mixture of both Arabic and Persian grammar and vocabulary.

Virtually all intellectual and literate pursuits were taken in Turkish language. Some ordinary people had to hire special "request-writers" (arzuhâlcis) to be able to communicate with the government. The ethnic groups continued to speak within their families and neighborhoods (mahalles) with their own languages (e.g., Jews, Greeks, Armenians, etc.) In villages where two or more populations lived together, the inhabitants would often speak each other's language. In cosmopolitan cities, people often spoke their family languages, many non-ethnic Turks spoke Turkish as a second language. Educated Ottoman Turks spoke Arabic and Persian, as these were the main foreign languages in the pre-Tanzimat era, with the former being used for science and the latter for literary affairs.

In the last two centuries, French and English emerged as popular languages, especially among the Christian Levantine communities. The elite learned French at school, and used European products as a fashion statement. The use of Ottoman Turkish for science and literature grew steadily under the Ottomans, while Persian declined in those functions. Ottoman Turkish, during the period, gained many loanwords from Arabic and Persian. Up to 88% of the vocabulary of a particular work would be borrowed from those two languages.

Linguistic groups were varied and overlapping. In the Balkan Peninsula, Slavic, Greek and Albanian speakers were the majority, but there were substantial minorities of Turks and Romance-speaking Vlachs. In most of Anatolia, Turkish was the majority language, but Greek, Armenian and, in the east and southeast, Kurdish were also spoken. In Syria, Iraq, Arabia, Egypt and north Africa, most of the population spoke varieties of Arabic with, above them, a Turkish-speaking elite. However, in no province of the Empire was there a unique language.

🔗 United States 🔗 Politics 🔗 Spirits

Andrew Johnson was drunk when he made his inaugural address as Vice President of the United States on March 4, 1865. Multiple sources suggest Johnson had been drunk for at least a week prior, he drank heavily the night before the inauguration, and he consumed either three glasses of whisky or one glass of French brandy the morning of the ceremony. Witnesses variously described Johnson's speech as incoherent, inane, self-aggrandizing, repetitive, hostile, sloppy, and overly long. He kissed the Bible when he took the oath of office, and he was too drunk to administer the oath of office to incoming senators. The incident presaged some of Johnson's difficulties as chief executive when he succeeded to the presidency 42 days later, following the assassination of Abraham Lincoln.

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.
