- Sperrgebiet (German, meaning “Prohibited Area”) is a diamond mining area in south-western Namibia, in the Namib Desert. It spans the Atlantic Ocean-facing coast from Oranjemund on the border with South Africa, to around 45 miles north of Lüderitz, a distance of 320 km (200 miles) north. The Sperrgebiet makes up three percent of Namibia’s land mass. Mining only takes place in five percent of the Sperrgebiet, with most of the area acting as a buffer zone. Members of the public are banned from entering most of the area, despite the creation of a national park in 2004.
- Claridge’s is a luxury hotel in Mayfair, central London. After the First World War, Claridge’s flourished due to demand from aristocrats who no longer maintained a London house, and under the leadership of Carte’s son, Rupert D’Oyly Carte, a new extension was built in the 1920s. Peter II of Yugoslavia and his wife spent much of the Second World War in exile at Claridge’s, and suite 212 was ceded by the United Kingdom to Yugoslavia for a single day (17 June 1945) to allow their heir, Crown Prince Alexander, to be born on Yugoslav soil.
- Graham’s number, named after Ronald Graham, is a large number that is an upper bound on the solution to a certain problem in Ramsey theory. The number is unimaginably larger than other well-known large numbers such as a googol, googolplex, and even larger than Skewes’ number and Moser’s number. Indeed, the observable universe is far too small to contain an ordinary digital representation of Graham’s number, assuming that each digit occupies at least one Planck volume.
- Highgate Cemetery is a cemetery located in Highgate, London, England. It soon became a fashionable place for burials and was much admired and visited. The Victorian attitude to death and its presentation led to the creation of a wealth of Gothic tombs and buildings. It occupies a spectacular south-facing hillside site slightly downhill from the top of the hill of Highgate itself. Although its most famous occupant in the east cemetery is probably Karl Marx (whose tomb’s attempted bombing in 1970 is still recalled by some Highgate residents), there are many other prominent figures, Victorian and otherwise, buried at Highgate Cemetery.
- Juche Thought/Idea is the official state ideology of North Korea. It teaches that “man is the master of everything and decides everything,” and that the Korean people are the masters of Korea’s revolution. Juche is a component of Kimilsungism, North Korea’s political system. The word literally means “main body” or “subject”; it has also been translated in North Korean sources as “independent stand” and the “spirit of self-reliance”.
- Pitot tube is a pressure measurement instrument used to measure fluid flow velocity. The pitot tube was invented by the French engineer Henri Pitot in the early 1700s and was modified to its modern form in the mid 1800s by French scientist Henry Darcy. It is widely used to determine the airspeed of an aircraft and to measure air and gas velocities in industrial applications.
