The Scottish Book (Polish: Księga Szkocka) was a thick notebook used by mathematicians of the Lwów School of Mathematics in Poland for jotting down problems meant to be solved. The notebook was named after the "Scottish Café" where it was kept.

Originally, the mathematicians who gathered at the cafe would write down the problems and equations directly on the cafe's marble table tops, but these would be erased at the end of each day, and so the record of the preceding discussions would be lost. The idea for the book was most likely originally suggested by Stefan Banach, or his wife, Łucja, who purchased a large notebook and left it with the proprietor of the cafe.

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.

The Office of Censorship was an emergency wartime agency set up by the United States federal government on December 19, 1941 to aid in the censorship of all communications coming into and going out of the United States, including its territories and the Philippines. The efforts of the Office of Censorship to balance the protection of sensitive war related information with the constitutional freedoms of the press is considered largely successful. The agency's implementation of censorship was done primarily through a voluntary regulatory code that was willingly adopted by the press. The phrase "loose lips sink ships" was popularized during World War II, which is a testament to the urgency Americans felt to protect information relating to the war effort. Radio broadcasts, newspapers, and newsreels were the primary ways Americans received their information about World War II and therefore were the medium most affected by the Office of Censorship code. The closure of the Office of Censorship in November 1945 corresponded with the ending of World War II.

The North American Phalanx was a secular utopian socialist commune located in Colts Neck Township, Monmouth County, New Jersey. The community was the longest-lived of about 30 Fourierist Associations in the United States which emerged during a brief burst of popularity during the decade of the 1840s.

The North American Phalanx was established in September 1843 and included the active participation of writer Albert Brisbane and newspaper publisher Horace Greeley, two of the leading figures of the Fourierist movement. The Association was disbanded in January 1856, following a catastrophic fire which destroyed a number of the community's productive enterprises. At the time of its termination it was the last of about 30 Fourierist Associations established during the 1840s still in existence and thus was the longest-lived.

The main residential dwelling of the phalanx, a three-story wooden structure, stood vacant until it was itself destroyed by fire in November 1972.

A Nipkow disk (sometimes Anglicized as Nipkov disk; patented in 1884), also known as scanning disk, is a mechanical, rotating, geometrically operating image scanning device, patented in 1885 by Paul Gottlieb Nipkow. This scanning disk was a fundamental component in mechanical television through the 1920s and 1930s.

Great ape personhood is a movement to extend personhood and some legal protections to the non-human members of the Hominidae or great ape family: chimpanzees, bonobos, gorillas, and orangutans.

The surprisingly popular answer is a wisdom of the crowd technique that taps into the expert minority opinion within a crowd. For a given question, a group is asked both "What do you think the right answer is?" and "What do you think the popular answer will be?" The answer that maximizes the average difference between the "right" answer and the "popular" answer is the "surprisingly popular" answer.
