Gas Mark
The gas mark is a temperature scale used on gas ovens and cookers in the United Kingdom, Republic of Ireland, Ireland and some Commonwealth of Nations countries. History Early gas ovens had no thermostats and it was up to the cook to continually adjust a manual valve to keep the oven at the desired temperature. For this and other reasons gas cookers were not popular; most users preferred the coal-fired open kitchen range. The breakthrough came in the 1920s when a manufacturer introduced the Regulo. REGULO was originally a proprietary name chosen by Radiation Ltd. to denote their new automatic temperature controller. In a series of press advertisements published on 13 May 1923 to announce their "New World" cooker it was stated that, by simply setting a pointer, the oven would go to the desired temperature and stay there without requiring further attention. The current (2025) online edition of the ''Oxford English Dictionary'' indicates that Radiation Ltd. applied to register ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Degrees Fahrenheit
The Fahrenheit scale () is a temperature scale based on one proposed in 1724 by the German-Polish physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (a salt). The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F (about 2.6 °F less than the modern value due to a later redefinition of the scale). For much of the 20th century, the Fahrenheit scale was defined by two fixed points with a 180 °F separation: the temperature at which pure water freezes was defined as 32 °F and the boiling point of water was defined to be 212 °F, both at sea level and under standard atmo ...

Degrees Celsius
The degree Celsius is the unit of temperature on the Celsius temperature scale "Celsius temperature scale, also called centigrade temperature scale, scale based on 0 ° for the melting point of water and 100 ° for the boiling point of water at 1 atm pressure." (originally known as the centigrade scale outside Sweden), one of two temperature scales used in the International System of Units (SI), the other being the closely related Kelvin scale. The degree Celsius (symbol: °C) can refer to a specific point on the Celsius temperature scale or to a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who proposed the first version of it in 1742. The unit was called ''centigrade'' in several languages (from the Latin ''centum'', which means 100, and ''gradus'', which means steps) for many years. In 1948, the International Committee for Weights and Measures renamed it to honor Celsius and also to remove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Balderdash And Piffle
''Balderdash and Piffle'' is a British television programme on BBC in which the writers of the ''Oxford English Dictionary'' asked the public for help in finding the origins and first known citations of a number of words and phrases. Presented by Victoria Coren, it was a companion to the dictionary's Wordhunt project. The '' OED'' panel consisted of John Simpson, the Chief Editor of the ''OED''; Peter Gilliver, who was also the captain of the Oxford University Press team in '' University Challenge: The Professionals''; and etymologist Tania Styles, who also appeared in the "dictionary corner" in '' Countdown''. Series 1 The first series of ''Balderdash and Piffle'' was originally broadcast in January 2006.Each programme was based around a letter; the first season covered the letters P, M, N, S, C, and B in that order. Following the conclusion of the first series, a follow-up seventh episode aired on 16 April 2006 with updates on the discoveries members of the public had made ...

Temperature
Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measurement, measured with a thermometer. It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), with the third being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible ...

Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the principal historical dictionary of the English language, published by Oxford University Press (OUP), a University of Oxford publishing house. The dictionary, which published its first edition in 1884, traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, and provides ongoing descriptions of English language usage in its variations around the world. In 1857, work first began on the dictionary, though the first edition was not published until 1884. It began to be published in unbound Serial (literature), fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 b ...
