The Shavian alphabet (also known as the Shaw alphabet) is an alphabet conceived as a way to provide simple, phonetic orthography for the English language to replace the difficulties of conventional spelling. It was posthumously funded by and named after Irish playwright Bernard Shaw. Shaw set three main criteria for the new alphabet: it should be (1) at least 40 letters; (2) as "phonetic" as possible (that is, letters should have a 1:1 correspondence to phonemes); and (3) distinct from the Latin alphabet to avoid the impression that the new spellings were simply "misspellings".

TV-B-Gone is a universal remote control device for turning off a large majority—about 85%—of the available brands of television sets in 2015. It was created to allow people in a public place to turn off nearby television sets. Its inventor has referred to it as "an environmental management device". The device is part of a key-chain, and, like other remote devices, is battery-powered. Although it can require up to 72 seconds for the device to find the proper code for a particular television receiver, the most popular televisions turn off in the first few seconds.

An emirp (prime spelled backwards) is a prime number that results in a different prime when its decimal digits are reversed. This definition excludes the related palindromic primes. The term reversible prime is used to mean the same as emirp, but may also, ambiguously, include the palindromic primes.

The sequence of emirps begins 13, 17, 31, 37, 71, 73, 79, 97, 107, 113, 149, 157, 167, 179, 199, 311, 337, 347, 359, 389, 701, 709, 733, 739, 743, 751, 761, 769, 907, 937, 941, 953, 967, 971, 983, 991, ... (sequence A006567 in the OEIS).

All non-palindromic permutable primes are emirps.

As of November 2009, the largest known emirp is 10¹⁰⁰⁰⁶+941992101×10⁴⁹⁹⁹+1, found by Jens Kruse Andersen in October 2007.

The term 'emirpimes' (singular) is used also in places to treat semiprimes in a similar way. That is, an emirpimes is a semiprime that is also a (distinct) semiprime upon reversing its digits.

The half cent was the smallest denomination of United States coin ever minted. It was first minted in 1793 and last minted in 1857. It was minted with five different designs.

Fractal compression is a lossy compression method for digital images, based on fractals. The method is best suited for textures and natural images, relying on the fact that parts of an image often resemble other parts of the same image. Fractal algorithms convert these parts into mathematical data called "fractal codes" which are used to recreate the encoded image.

McDonald's Corporation v Steel & Morris [1997] EWHC QB 366, known as "the McLibel case", was an English lawsuit for libel filed by McDonald's Corporation against environmental activists Helen Steel and David Morris (often referred to as "The McLibel Two") over a factsheet critical of the company. Each of two hearings in English courts found some of the leaflet's contested claims to be libellous and others to be true.

The original case lasted nearly ten years which, according to the BBC, made it the longest-running libel case in English history. McDonald's announced it did not plan to collect the £40,000 it was awarded by the courts. Following the decision, the European Court of Human Rights (ECHR) ruled in Steel & Morris v United Kingdom the pair had been denied a fair trial, in breach of Article 6 of the European Convention on Human Rights (right to a fair trial) and their conduct should have been protected by Article 10 of the Convention, which protects the right to freedom of expression. The court awarded a judgement of £57,000 against the UK government. McDonald's itself was not involved in, or a party to, this action, as applications to the ECHR are independent cases filed against the relevant state.

Franny Armstrong and Ken Loach made a documentary film, McLibel, about the case.

Simpson's paradox, which goes by several names, is a phenomenon in probability and statistics, in which a trend appears in several different groups of data but disappears or reverses when these groups are combined. This result is often encountered in social-science and medical-science statistics and is particularly problematic when frequency data is unduly given causal interpretations. The paradox can be resolved when causal relations are appropriately addressed in the statistical modeling.

Simpson's paradox has been used as an exemplar to illustrate to the non-specialist or public audience the kind of misleading results mis-applied statistics can generate. Martin Gardner wrote a popular account of Simpson's paradox in his March 1976 Mathematical Games column in Scientific American.

Edward H. Simpson first described this phenomenon in a technical paper in 1951, but the statisticians Karl Pearson et al., in 1899, and Udny Yule, in 1903, had mentioned similar effects earlier. The name Simpson's paradox was introduced by Colin R. Blyth in 1972.

It is also referred to as or Simpson's reversal, Yule–Simpson effect, amalgamation paradox, or reversal paradox.

Dogme 95 is a 1995 avant-garde filmmaking movement founded by the Danish directors Lars von Trier and Thomas Vinterberg, who created the "Dogme 95 Manifesto" and the "Vows of Chastity" (Danish: kyskhedsløfter). These were rules to create films based on the traditional values of story, acting, and theme, and excluding the use of elaborate special effects or technology. It was supposedly created as an attempt to "take back power for the directors as artists", as opposed to the studio. They were later joined by fellow Danish directors Kristian Levring and Søren Kragh-Jacobsen, forming the Dogme 95 Collective or the Dogme Brethren. Dogme (pronounced [ˈtʌwmə]) is the Danish word for dogma.

PBworks (formerly PBwiki) is a commercial real-time collaborative editing (RTCE) system created by David Weekly, with Ramit Sethi and Nathan Schmidt, who joined shortly thereafter as co-founders. Based in San Mateo, California, United States, the company operates on a freemium basis, offering basic features free of charge and more advanced features for a fee.

PBworks' investors include Mohr Davidow Ventures and the Seraph Group, as well as angel investors Ron Conway and Chris Yeh.

Dry cask storage is a method of storing high-level radioactive waste, such as spent nuclear fuel that has already been cooled in a spent fuel pool for at least one year and often as much as ten years. Casks are typically steel cylinders that are either welded or bolted closed. The fuel rods inside are surrounded by inert gas. Ideally, the steel cylinder provides leak-tight containment of the spent fuel. Each cylinder is surrounded by additional steel, concrete, or other material to provide radiation shielding to workers and members of the public.

There are various dry storage cask system designs. With some designs, the steel cylinders containing the fuel are placed vertically in a concrete vault; other designs orient the cylinders horizontally. The concrete vaults provide the radiation shielding. Other cask designs orient the steel cylinder vertically on a concrete pad at a dry cask storage site and use both metal and concrete outer cylinders for radiation shielding. Until 2024/25, there was no long term permanent storage facility anywhere in the world, and most countries still don't have a facility; dry cask storage is designed as an interim safer solution than spent fuel pool storage.

Some of the cask designs can be used for both storage and transportation. Three companies – Holtec International, NAC International and Areva-Transnuclear NUHOMS – are marketing Independent Spent Fuel Storage Installations (ISFSI) based upon an unshielded multi-purpose canister which is transported and stored in on-site vertical or horizontal shielded storage modules constructed of steel and concrete.
