🔗 China 🔗 Spirits

Baijiu (Chinese: 白酒; pinyin: báijiǔ; literally: 'white (clear) liquor'), also known as shaojiu (烧酒/燒酒), is a clear Chinese distilled liquor of typically 40%-50%. Each type of baijiu uses a distinct type of Qū during the fermentation process in the distillery for the distinct and characteristic flavour profile.

Báijiǔ is a clear liquid usually distilled from fermented sorghum, although other grains may be used; some southeastern Chinese styles may employ rice or glutinous rice, while other Chinese varieties may use wheat, barley, millet, or even Job's tears (Chinese: 薏苡 yìyǐ) in their mash bills. The qū starter culture used in the production of baijiu is usually made from pulverized wheat grain or steamed rice.

Because of its clarity, baijiu can appear similar to several other East Asian liquors, but it often has a significantly higher alcohol content than, for example, Japanese shōchū (25%) or Korean soju (20–45%). Despite being a white spirit, its flavour more closely resembles a rich spirit like whisky in terms of complexity of flavour and sensation.

Baijiu is the world's bestselling spirit, with five billion litres sold in 2016. That number was up to 10.8 billion liters sold in 2018, more than whisky, vodka, gin, rum and tequila combined. Baijiu's popularity in China makes it the world's most consumed spirit, but outside of China it is not well known.

🔗 Mathematics

In mathematical logic, Tarski's high school algebra problem was a question posed by Alfred Tarski. It asks whether there are identities involving addition, multiplication, and exponentiation over the positive integers that cannot be proved using eleven axioms about these operations that are taught in high-school-level mathematics. The question was solved in 1980 by Alex Wilkie, who showed that such unprovable identities do exist.

🔗 China 🔗 Linguistics 🔗 Food and drink 🔗 Linguistics/Etymology 🔗 Food and drink/Beverages

The etymology of the word tea can be traced back to the various Chinese pronunciations of the word. Nearly all the words for tea worldwide, fall into three broad groups: te, cha and chai, which reflected the history of transmission of tea drinking culture and trade from China to countries around the world. The few exceptions of words for tea that do not fall into these three broad groups are mostly from the minor languages from the botanical homeland of the tea plant, and likely to be the ultimate origin of the Chinese words for tea. Notably, none of these words mean 'dinner' or a late afternoon meal.

Gambling on papal elections has at least a 500-year history. Betting on 16th-century papal conclaves are among the first documented examples of gambling on election outcomes. During the same period, gambling was also common on the outcomes of secular Italian elections, such as that of the Doge of Venice. Leighton Vaughan Williams and David Paton employ a unique dataset to investigate betting on the 2013 papal election, set within the context of the history of betting on papal conclaves.

Boaty McBoatface (also known as Boaty) is the British lead boat in a fleet of three robotic lithium battery–powered autonomous underwater vehicles (AUVs) of the Autosub Long Range (ALR) class. Launched in 2017 and carried on board the polar scientific research vessel RRS Sir David Attenborough, she is a focal point of the Polar Explorer Programme of the UK Government.

Boaty and her two fleet-mates are part of the UK National Marine Equipment Pool and owned by the National Oceanography Centre in Southampton. She is classified as an "autosub long range (ALR) autonomous underwater vehicle", and will use her onboard sensors to map the movement of deep waters that play a vital role in regulating the Earth's climate.

🔗 Medicine 🔗 Dance

Dancing mania (also known as dancing plague, choreomania, St. John's Dance and St. Vitus's Dance) was a social phenomenon that occurred primarily in mainland Europe between the 14th and 17th centuries. It involved groups of people dancing erratically, sometimes thousands at a time. The mania affected men, women, and children who danced until they collapsed from exhaustion. One of the first major outbreaks was in Aachen, in the Holy Roman Empire, in 1374, and it quickly spread throughout Europe; one particularly notable outbreak occurred in Strasbourg in 1518, also in the Holy Roman Empire.

Affecting thousands of people across several centuries, dancing mania was not an isolated event, and was well documented in contemporary reports. It was nevertheless poorly understood, and remedies were based on guesswork. Often musicians accompanied dancers, due to a belief that music would treat the mania, but this tactic sometimes backfired by encouraging more to join in. There is no consensus among modern-day scholars as to the cause of dancing mania.

The several theories proposed range from religious cults being behind the processions to people dancing to relieve themselves of stress and put the poverty of the period out of their minds. It is speculated to have been a mass psychogenic illness, in which physical symptoms with no known physical cause are observed to affect a group of people, as a form of social influence.

🔗 Africa 🔗 Highways 🔗 Highways/Road transport 🔗 Highways/African Highways

The Trans-African Highway network comprises transcontinental road projects in Africa being developed by the United Nations Economic Commission for Africa (UNECA), the African Development Bank (ADB), and the African Union in conjunction with regional international communities. They aim to promote trade and alleviate poverty in Africa through highway infrastructure development and the management of road-based trade corridors. The total length of the nine highways in the network is 56,683 km (35,221 mi).

In some documents the highways are referred to as "Trans-African Corridors" or "Road Corridors" rather than highways. The name Trans-African Highway and its variants are not in wide common usage outside of planning and development circles, and as of 2014 one does not see them signposted as such or labelled on maps, except in Kenya and Uganda where the Mombasa–Nairobi–Kampala–Fort Portal section (or the Kampala–Kigali feeder road) of Trans-African Highway 8 is sometimes referred to as the "Trans-Africa Highway".

The Kearny fallout meter, or KFM, is an expedient radiation meter. It is designed such that someone with a normal mechanical ability would be able to construct it before or during a nuclear attack, using common household items.

The Kearny fallout meter was developed by Cresson Kearny from research performed at Oak Ridge National Laboratory and published in the civil defense manual Nuclear War Survival Skills (ISBN 0-942487-01-X). The plans were originally released in Oak Ridge National Laboratory publication ORNL-5040, The KFM, A Homemade Yet Accurate and Dependable Fallout Meter and have been formatted in a newsprint-ready layout so that they may be quickly printed with accurate dimensions in local newspapers. It must be built from a correctly scaled copy of the plans; photocopies and printouts of digital copies may not be to scale.

🔗 Food and drink

MagiCans were special, mechanical cans used by The Coca-Cola Company in the United States of America as a part of their $100-million "Magic Summer '90" promotion. The MagiCan promotion began on May 7, 1990, and ended on May 31.

In this promotion, some Coca-Cola cans had cash prizes or gift certificates inside instead of Coca-Cola. The prizes were spring-loaded to pop out of the opening once the can was opened. The prize would either be money, from $1 to $500, or coupons redeemable for trips or merchandise. The total giveaway of cash and prize coupons was $4 million. The original plan was to randomly distribute about 750,000 MagiCans among the 200 million cans of Coca-Cola Classic in circulation at any one time. To make the cans feel and weigh normal, and prevent people from easily finding the prize cans, a sealed area within the cans was filled with a mixture of chlorinated water and a foul-smelling substance to discourage drinking. Though initially a great success, leading to a rise in sales, technical difficulties led to the promotion's early termination.
